Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2007.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.

A Situated Conversational Assistant (SCA) is a system with sensing, acting and speech synthesis/recognition abilities, which engages in physically situated natural language conversation with human partners and assists them in carrying out tasks. This thesis addresses some prerequisites towards an ideal truly cooperative SCA through the development of a computational model of embodied, situated language agents and implementation of the model in the form of an interactive, conversational robot. The proposed model produces systems that are capable of a core set of situated natural language communication skills, and provides leverage for many extensions towards the ideal SCA, such as mind reading skills. The central idea is to endow agents with a sensor-updated "structured blackboard" representational structure called a Grounded Situation Model (GSM), which is closely related to the cognitive psychology notion of situation models. The GSM serves as a workspace with contents similar to a "theatrical stage" in the agent's "mind". The GSM may be filled either with the contents of the agent's present here-and-now physical situation, or a past situation that is being recalled, or an imaginary situation that is being described or planned.
(cont.) Furthermore, the GSM contains descriptions of both physical (such as objects) as well as mental aspects of situations (such as beliefs of others). Most importantly, the proposed GSM design enables bidirectional translation between linguistic descriptions and perceptual data / expectations. To demonstrate viability, an instance of the model was implemented on a manipulator robot with touch, vision, and speech synthesis/recognition. The robot grasps the semantics of a range of words and speech acts related to cooperative manipulation of objects on a table top situated between the robot and human. The robot's language comprehension abilities are comparable to those implied by a standard and widely used test of children's language comprehension (the Token Test), and in some directions also surpass those abilities. Not only the viability but also the effectiveness of the GSM proposal is thus demonstrated, through a real-world autonomous robot that performs comparably to those capabilities of a normally-developing three-year old child which are assessed by the token test.

Full textAbstract:
Conversational interfaces (CIs) have been a trending topic in recent years. As of the last decade, CIs have emerged with the aim of simplifying human-machine interactions and found a wide use case in the market. For example, Siri and Google Assistant are some of the most well-known CIs developed by the tech giants Apple and Google. The digital landscape has evolved from web, to mobile apps, to recently CIs. Nowadays, CIs, in particular chatbots and voicebots, are becoming increasingly common. Whether navigating the web or messaging on a phone, it is likely that CIs have been confronted offering the user help.However, CIs have not managed to reach a large-scale use. Furthermore, the reasons regarding the challenges faced by CIs as well as their usability are not greatly explored. In this thesis, we explore the most relevant uses of CIs and the reasons hindering a widespread use of CIs. Our goal is to provide an insight into CIs’ uses and list the reasons regarding the challenges faced by CIs. The research study followed a mixed method approach connecting an explorative qualitative literature study, a survey and an interview. The data was collected by using a systematic mapping approach for it being more suitable for conducting an effective literature review. The survey and the interview were conducted in order to confirm the findings.According to our research, it was found that the most common use cases of CIs were in customer service, sales, travel and bookings, education, healthcare and as voice assistants. The most prominent challenges faced by CIs were poor usability, language processing and understanding, speech recognition and natural language generation and security and privacy. As a conclusion, the future looks promising for CIs, however, they need to be furher researched and developed in order to help them reach a widespread use in the future.Konversation Gränssnitt (CIs) har varit ett trendande ämne de senaste åren. Sedan det senaste decenniet har CIs kommit fram i syfte att förenkla interaktioner mellan människor och maskiner och har hittat ett brett användningsfall på marknaden. Det digitala landskapet har utvecklats från webb, till mobila appar till nyligen CI. Numera blir CIs, i synnerhet chatbots och voicebots, allt vanligare. Vare sig du navigerar på webben eller meddelanden i en telefon, är det troligt att CIs har konfronterats med att erbjuda användaren hjälp.CIs har dock inte lyckats uppnå storskalig användning. Dessutom är orsakerna till de utmaningar som CIs står inför och deras användbarhet inte utforskas i hög grad. I den här avhandlingen undersöker vi de mest relevanta användningarna av CIs och orsakerna till en utbredd användning av CIs. Vårt mål är att ge en inblick i CI: s användningar och lista orsakerna till de utmaningar som CIs står inför. Forskningsstudien följde en blandad metodstrategi som ansluter en utforskande kvalitativ litteraturstudie, en undersökning och en intervju. Uppgifterna samlades in med hjälp av en systematisk kartläggningsätt för att göra dem mer lämpliga för att genomföra en effektiv litteraturgranskning. Undersökningen och intervjun genomfördes för att bekräfta resultaten.Enligt vår forskning konstaterades att de vanligaste användningsfallen för CIs var kundservice, försäljning, resor och bokningar, utbildning, sjukvård och som röstassistenter. De mest framstående utmaningarna för CIs var dålig användbarhet, språkhantering och förståelse, taligenkänning och naturlig språkgenerering och säkerhet och integritet. Sammanfattningsvis ser framtiden lovande ut för CIs, men de måste undersökas och utvecklas ytterligare för att hjälpa dem att uppnå utbredd användning i framtiden.

Kozlova, Iryna. "Negotiation of Identities by International Teaching Assistants through the Use of Humor in University Classrooms." Digital Archive @ GSU, 2008. http://digitalarchive.gsu.edu/alesl_diss/2.
Full textAbstract:
Research on international teaching assistants (ITAs) often highlights that ITAs have at least two identities, an identity of a teacher and a student (e.g., Jenkins, 2000). Since American classrooms foster a variety of behaviors that are negotiated by instructors and students, ITAs may identify themselves with students during behavior negotiation when building rapport, especially by exchanging jokes (Unger-Gallagher, 1991). Making their student identity relevant may distort the teacher-student relationship, which ITAs might need to renegotiate. Little research has been done to show whether ITA student identity actually emerges and if does, then how. This study addresses the questions of what attributes of ITA's identities emerge during humorous exchanges with their students, how these attributes shape the teacher-student relationship, and what role humor plays in the identity negotiation process between the ITAs and their students in the university classroom. Four ITAs, all non-native English speakers, participated in this microethnographic study. This study informs research on social identity in that, most of the time, participants made the attributes of their teacher identity relevant, with teacher authority emerging as the most important attribute. While enacting their teacher identity through humorous exchanges, ITAs built rapport and created affiliation with their students. Although humor led to establishing good relationships, it did not lead to the emergence of ITA student identity. This study also contributes to research on humor in that it makes a distinction between the concepts of the target and the butt which allows for deeper understanding of how humor is used to negotiate identity. It also introduces the target switch, or a particular type of counter teasing, in which the initial target redirects humorous aggression to the teaser, thus making her/him the target and a potential butt of the tease. An optimistic finding for ITA research and research on the use of humor by non-native speakers is that even without extensive experience with American culture in general, ITAs can use humor rooted in the local context to negotiate different classroom behaviors and their identities with their students.

Full textAbstract:
Ces dernières années, les progrès en sciences de la gestion et de l’information ont transformé la Gestion de Processus d’Affaires (Business Process Management, BPM) en un sujet important, tant du côté de l’industrie que de celui de la recherche. Le BPM utilise des processus métiers pour améliorer la performance opérationnelle des organisations. Les processus métiers établissent un lien entre les personnes, les systèmes, et les différentes organisations, dans le but de créer de la valeur pour les parties prenantes. La cible de notre travail est la famille des systèmes BPM. Un système BPM est un système logiciel générique guidé par des modèles explicites de processus métier avec pour objectif d’exécuter et de gérer des processus opérationnels. Malgré le vaste éventail de sujets traités par ce domaine de recherche, il reste encore quelques questions qui méritent une étude plus approfondie. Un problème particulier concerne la médiation entre les systèmes BPM et les humains. L’interaction homme-machine dans ces systèmes repose sur des interfaces standard basées sur des listes de taches et des formulaires, ce qui est très contraignant pour les utilisateurs.Ceux-ci ont non seulement des difficultés à exécuter leurs processus métier, mais aussi a trouver le processus métier le mieux adapté à leurs besoins. Il serait beaucoup plus efficace d’utiliser des dialogues en langage naturel. Malheureusement les langages de modélisation de processus ne permettent pas de capturer ni de modéliser un domaine de discours. Le travail présent propose une approche originale de gestion du dialogue basée sur des systèmes multi-agents pour l’exécution des processus métier. La motivation globale pour ce travail fut de concevoir un modèle de dialogue extensible à différents domaines. Ce modèle s’appuie sur les ontologies de domaine, nécessitant un minimum d’effort d’adaptation pour améliorer l’interaction. Les résultats montrent tout le potentiel de notre approche multi-agent pour réaliser une médiation automatiquement, sans qu’il soit nécessaire de reconstruire les modèles de processus métierOver the last few years, the advances in management science and information technology have transformed the business process management (BPM) discipline into an important topic for both industry and academy. BPM uses business processes as the means for improving the operational performance of organizations, and setting processes are at the heart of BPM allows linking together people, systems, and different organizations to deliver value to stakeholders. The target of our work is the family of BPM systems. A BPM system is a generic software system that is driven by explicit process designs to enact and manage operational business processes. Despite the wide range of topics addressed by the academy on business processes, there are still aspects not addressed by prior research. A particular problem in this regard is the mediation between BPM systems and humans. Human interaction in those systems follows a standard user interface based predominantly on work item lists and forms. Thus, there is little room for creativity for users. They have not only difficulties in enacting their processes but also for searching the most suitable one for their needs. It would be more efficient to let humans interact in natural language. However, process modeling languages are an insufficient means of capturing and representing the domain of discourse. The present thesis develops an original approach to agent dialog management for the problem of business process enactment. The overarching motivation for this work was to design a dialog model scalable to different domains. The model relies on domain and business process ontologies, and necessitates a minimum effort of adaptation on ontologies to improve the interaction. Results indicate the potential of our agent-based approach to generate natural language

Full textAbstract:
Afin d’être considérés comme des partenaires crédibles lors d’une interaction, les agents virtuels doivent transmettre une attitude sociale adéquate. Cette attitude sociale exprimée par l’agent doit refléter la situation dans laquelle il se trouve. L’agent doit donc prendre en compte son rôle et sa relation sociale vis à vis de son interlocuteur lorsqu’il choisit comment réagir au cours de l’interaction. Afin de construire un tel agent capable de raisonner en fonction de son rôle et de sa relation, et capable d’adapter son attitude sociale, nous avons construit un modèle de prise de décision sociale. Dans un premier temps, nous formalisons la dynamique de la relation sociale à travers une combinaison de buts et de croyances. Puis, nous définissons un modèle de prise de décision basé sur les buts sociaux et situationnels de l’agent. Pour finir, nous avons réalisé une étude perceptive dans un contexte d’interaction tuteur/enfant virtuels au cours de laquelle les participants évaluaient l’attitude sociale du tuteur envers l’enfant. La relation sociale et le rôle social du tuteur étaient manipulés par notre modèle. Les résultats montrent qu’à la fois le rôle et la relation du tuteur ont une influence sur son attitude sociale perçueTo be perceived as believable partners in human-machine interactions, virtual agents have to express adequate social attitudes. The social attitude expressed by an agent should reflect the social situation of the interaction. The agent ought to take into account its role and its social relation toward its interactants when deciding how to react in the interaction. To build such an agent able to reason about its role and relation and to adapt its social attitude, we built a model of social decision making. First, we formalized the dynamics of the social relation through a combination of goals and beliefs. Then, we designed a decision making model based on the social goals and the situational goals of the agent. Finally, we conducted an empirical study in the context of virtual tutor-child interaction where participants evaluated the tutor’s perceived social attitude towards the child while the tutor’s social role and relation were manipulated by our model. Results showed that both role and social relation have an influence on the agent’s perceived social attitude

Full textAbstract:
Chatbots, also called conversational agents, with speech interfaces are being used to a greater and greater extent, but there are still many areas that are not completely explored. The idea of this project was born out of the belief that there is a need for an assistant in the kitchen that is able to search for recipes, answer questions regarding them and guide and assist the user throughout the cooking process, all through conversation since the hands are busy. This paper begins with an introduction in the subject of conversational agents and the related technology, then similar, already existing studies and methods are presented with their pros and cons. After follows an in-depth explanation on how the program was constructed into a working kitchen assistant. Lastly, the users’ experiences of the performance and usability of the program was evaluated through tests and discussed. It turns out that conversational agents definitely can be integrated in the kitchen, and according to several sources, in a few years they will be implemented in all possible areas and change the technology of our time.Konversationsrobotar med talgränssnitt används i allt större och större utsträckning men det finns fortfarande många områden som inte är helt utforskade. Idén till det här arbetet föddes ur uppfattningen att det existerar ett behov av en hjälpreda till köket som kan söka recept, svara på frågor kring receptet och vägleda och hjälpa användaren genom hela matlagningsprocessen i muntligt form eftersom händerna är upptagna med annat. Det här arbetet börjar med en introduktion i ämnet kring konversationsrobotar och tekniken bakom, sedan presenteras liknande arbeten och metoder som redan existerar inom området. Sedan följer en djupdykning i hur det framtagna programmet i detta arbete utvecklats fram till en fungerande matlagningsassisten. Till slut presenteras och diskuteras upplevelsen och användbarheten av konversationsroboten hos människor baserat på tester som gjorts. Det visar sig att konversationsrobotar mycket väl kan vara av användning i köket, och enligt flera källor kommer de att inom en snar framtid lavinartat implementeras i alla möjliga områden och förändra tekniken i vårt samhälle.

Full textAbstract:
When reviewing the performance of Intelligent Virtual Assistants (IVAs), it is desirable to prioritize conversations involving misunderstood human inputs. These conversations uncover error in natural language understanding and help prioritize and expedite improvements to the IVA. As human reviewer time is valuable and manual analysis is time consuming, prioritizing the conversations where misunderstanding has likely occurred reduces costs and speeds improvement. A system for measuring the posthoc risk of missed intent associated with a single human input is presented. Numerous indicators of risk are explored and implemented. These indicators are combined using various means and evaluated on real world data. In addition, the ability for the system to adapt to different domains of language is explored. Finally, the system performance in identifying errors in IVA understanding is compared to that of human reviewers and multiple aspects of system deployment for commercial use are discussed.

People who are not professional storytellers sometimes have difficulty putting together a coherent and engaging story, even when it is about their own experiences. However, consider putting the same person in a conversation with a sympathetic, interested and questioning listener, suddenly the story comes alive. There's something about the situation of being in a conversation that encourages people to stay on topic, make coherent points, and make the story interesting for a listener. Raconteur is a system for conversational storytelling between a storyteller and a viewer. It provides intelligent assistance in illustrating a life story with photos and videos from a personal media library. Raconteur performs natural language processing on a text chat between two users and recommends appropriate media items from the annotated library, each file with one or a few sentences in unrestricted English. A large commonsense knowledge base and a novel commonsense inference technique are used to understand event relations and determine narration similarity using concept vector computation that goes beyond keyword matching or word co-occurrence based techniques. Furthermore, by identifying larger scale story patterns such as problem and resolution or expectation violation, it assists users in continuing the chatted story coherently. A small user study shows that people find Raconteur's suggestions helpful in real-time storytelling and its interaction design engaging to explore stories together.

Full textAbstract:
Purpose: The purpose of this phenomenological research study was to describe the behaviors that exemplary educational services assistant superintendents practice to lead their organizations through conversation as depicted by Groysberg and Slind’s (2012b) 4 elements of conversational leadership: intimacy, interactivity, inclusion, and intentionality.
Methodology: A qualitative, phenomenological approach was used in this study in order to describe the lived experiences and behaviors of exemplary leaders. The target population was educational services assistant superintendents in Southern California. Participants were selected using a purposeful, nonprobability, convenience sampling. Data gathering took the form of semistructured, in-depth interviews, observations, and artifact collection. Interviews were conducted using a protocol designed by the team of collaborative peer researchers in order to gain insight into leaders’ perceptions of their conversational leadership experiences. Triangulation with observational notes and artifacts served to increase the validity of interview data. All data were entered into NVivo software to assist in analyzing patterns and predicting themes for coding.
Findings: Close analysis of interview notes and transcripts, observations, and artifacts resulted in total of 25 themes and 447 frequencies among the 4 elements of conversational leadership. Ten key findings were identified across the areas of intimacy, interactivity, inclusion, and intentionality.
Conclusions: The study supported the 4 elements of conversational leadership proposed by Groysberg and Slind (2012b) and identified specific behaviors that exemplary leaders practice within each. Four conclusions were drawn based on the data and findings. Educational services assistant superintendents who want to become transformational conversational leaders should (a) practice careful listening to create an environment of trust and support intimate communication structures within their organizations, (b) facilitate a variety of collaborative groups using a process for the exchange of ideas to establish dynamically interactive organizations, (c) invite shared leadership opportunities to nurture a climate of inclusivity, and (d) continually focus conversation of the organization’s purpose to ensure collective understanding and clarity of direction.
Recommendations: Further research of private sector leaders and assistant superintendents in regions outside of Southern California should be conducted. In addition, the element of intimacy in the workplace requires more attention in the field of conversational leadership.

Full textAbstract:
Avec le nombre croissant d'utilisateurs novices des applications informatiques, le besoin d'une aide efficace est devenu critique. Afin de répondre à ce besoins, nous suggérons d'utiliser un Agent Conversationnel Assistant (ACA), c'est-à-dire une interface permettant l'utilisation de la langue naturelle (en effet celle-ci est utilisée spontanément dès qu'un problème surgit) ainsi qu'une présence rassurante pour les utilisateurs.Une étude préliminaire détaille la constitution (en combinant la collecte et l'utilisation de thesaurus) d'un corpus de requêtes dont nous justifions le besoin. Ce corpus de 11626 requêtes est comparé avec d'autres corpus existants et nous montrons qu'il couvre le domaine étudié d'aide et que de plus, il contient des requêtes portant d'une part sur le contrôle de l'application et d'autre part des phrases de 'clavardage'. Ce corpus fournit une base saine pour la conception d'un analyseur syntactico-sémantique de requêtes en langage naturel, utilisant un jeu de classes (keys) sémantiques, un jeu de règles d'analyse et un jeu de règles de transformation. En entrée, les requêtes sont exprimées dans un langage formel (DAFT) pour lequel nous proposons une syntaxe et une sémantique. L'analyseur est alors évalué en comparant une annotation manuelle avec les requêtes produites automatiquement et nous étudions l'usage de techniques d'apprentissage supervisé afin d'identifier les classes d'activités conversationnelles. La méthodologie employée est validée via l'intégration d'un ACA dans une application Web existante , dédiée au prototypage collectif de la musique sur Internet. Enfin, nous décrivons l'architecture requise pour implémenter un agent rationnel qui a pour rôle de définir les réactions aux requêtes formelles des usagers, exprimées en DAFT ainsi que le modèle de l'application assistée, mettant ainsi en lumière le besoin d'un modèle cognitif.

Para las comunidades más pequeñas y nativas en un país, es muy difícil encontrar información que se encuentre en su idioma original, esto debido a que su lengua no tiene el alcance ni la cantidad suficiente de hablantes, para poder seguir siendo transmitida. A este tipo de lengua se le denomina minoritaria o de pocos recursos.
Una de las principales formas en las que el gobierno incentiva el proceso de multilingüismo es proporcionando educación en el idioma nativo a su población, tal es el caso de los hablantes de Shipibo-Konibo que se encuentran dispersos a lo largo de la amazonía del Perú. Ellos cuentan con colegios donde se les imparten clases en su lengua nativa para los niveles de primaria y secundaria. Sin embargo, una necesidad con la que cuentan los pobladores es que la cantidad de material educativo completamente traducido a Shipibo-Konibo es reducida. Esto debido a que el proceso de traducción es muy costoso y poco confiable.
El Grupo de investigación en Inteligencia Artificial de la PUCP (IA-PUCP, ex GRPIAA) ha desarrollado una plataforma que utiliza corpus paralelos la creación de un modelo estadístico de traducción automática para las lenguas Shipibo-Konibo y español. Este modelo sufre de ciertas limitantes, entre las cuales tenemos: la cantidad de recursos bibliográficos y material completamente traducido, esto debido a que al ser una lengua minoritaria o de pocos recursos carecen de facilidades para la generación de nuevos corpus. Por otro lado, se desea mejorar el modelo actual en parámetros de eficiencia y obtener mejores resultados en las traducciones.
En este contexto nace la pregunta que motiva el presente trabajo: ¿de qué manera podemos incrementar el corpus paralelo de forma eficiente y confiable para la mejora del modelo actual de traducción automática? Por consiguiente, en el presente trabajo se propone desarrollar un agente conversacional que permita la generación de nuevos corpus paralelos entre Shipibo-Konibo y español que permitan mejorar un modelo de traducción automática neuronal en las lenguas ya mencionadas.Tesis

This problem is challenging because assistance models have to unify two different, sometimes contradictory, points of view upon the same entity: the application at runtime. The hypothesis defended in this work is that using a perceptual-driven representation to organize information in the assistance model resolves (at least partially) the unification problem. We explore this hypothesis on the issue of perceptual grouping of interface components (or widgets). To obtain the representation, we implement an algorithm derived from the gestalt theory. This work has led to the development of a family of so-called “dialogical components” used as modeling items. This family of components, called daft-swing, fits into a generic architecture of query/answer processing, called daft, developed in previous work. The problematic of perceptual grouping and the synthesis of assistance models are then handled via two case studies: the first one, which led to the development of a software tool called dom-filter, describes the implementation of the perceptual grouping algorithm in the context of an experience of model synthesis from a web application. The second one, which led to the development of a software tool called kiwi, is more focused on the synthesis of models involving user’s actions as the main source of information. Each tool produces assistance models based on daft-swing components. Hence these models are directly embeddable in the daft architecture and can be used by its assisting agent

Ce travail est une contribution à l'analyse des situations de travail à distance, dans une perspective psychosociale. Il porte, en particulier, sur l'étude de situations d'assistance-dépannage informatique, et notamment de conversations téléphoniques entre experts et utilisateurs. L'assistance-dépannage informatique par téléphone désigne, en fait, le support ou l'aide aux utilisateurs, et consiste à « réparer à travers l'usage du langage ». L'objectif de cette étude est, à la fois, de mieux comprendre ces situations de travail, et cette nouvelle professionnalité « être dépanneur à distance » ; et également de mettre en évidence les mécanismes en jeu dans les conversations entre experts et utilisateurs. Nous nous intéressons donc, ici, à la structure générale des appels et aux différentes séquences qui les composent ; à la façon dont l'expert s'adapte à son interlocuteur ; aux activités de gestion du problème et à celles de gestion du dialogue ; aux connaissances et aux compétences des partenaires de cet échangeThe dissertation offers a contribution from a psychosocial perspective to the analysis of distant work situations. It is concerned with situations in informatics involving helpdesk and support service, and focuses on telephone conversations between experts and users. Telephone-based helpdesk in informatics refers to a service of help and support and actually consists in "repairing through the use of language". The aim of this study is both to understand these particular working situations better, and to stress the mechanisms involved in an expert-user relationship. The point of interest is therefore the general structure of the different phone calls and of the different sequences composing those calls. In particular, the analysis is concerned with the way the expert adapt himself to the client in the conversation, with the various activities of problem management on a technical level and of dialogue management on a relational level, and with the skills and knowledge of the two participants in the exchange

Full textAbstract:
The subject of this study is language use in a special type of social activity: the exchange of goods, services and information in a commercial setting. The main aim is to gain an understanding of the work that shop assistants perform using language. In the analysis, the focus is on verbal routine work. One part of the analysis thus entails mapping the typical utterances and conversational sequences related to such activities. Another part involves investigating how much non-task-oriented interaction the various activities require or “tolerate”, for instance, in the form of “small talk”. A central theme in the study is the interactants’ conversational rights and obligations, from the perspective of politeness theory, especially Fraser’s theory of the conversational contract. The service encounters are categorised as activity types, according to Levinson’s activity theory. In the comparative parts of the study, the concept of pragmeme is used as a tool to examine different realisations of prototypical situated communicative acts. The empirical material consists of authentic conversations, analysed by methods borrowed from conversation analysis. The conversations were recorded at a supermarket checkout till, a deli counter with manual service and an information desk in a bookshop. It turned out that only a few of the customer conversations were without complications. At the supermarket till, for instance, only one out of four conversations was completely routine and unproblematic. Also presented is a diachronic investigation of the norms relating to service encounters that have been taking place in shops since the 1940s. The main sources here are manuals and study materials for shop employees, together with interviews and material gathered from role playing. In this part of the study, a number of features in the historical change process are described, for instance in the manner of addressing people and the use of politeness expressions.

Full textAbstract:
Background: E-commerce is widespread in today’s shopping routines and conversational commerce (CC) as an expansion, aims at integrating customers and businesses on a whole new level. Through the application of chatbots fueled by artificial intelligence, a more personal and individual way of remote shopping is offered. Purpose: Our research question What potential attributes of AI-fueled CC applications and their possible inherent characteristics are determining the willingness to use them and to what extent, in the context of digital natives living in Sweden and Germany? aims at identifying the demanded attributes of conversational commerce from a consumer perspective. Method: We facilitate a quantitative questionnaire with 118 valid answers to administer a traditional full-profile conjoint analysis. Conclusion: Our results indicate that German digital natives deem a CC application’s behavior as the most important attribute, followed by payment method, personality and communication form (voice or text). The Swedish digital natives however, attach the most importance to the payment method, followed by behavior, communication form and personality. Both have in common that they prefer a rather passive behavior over being actively approached, a personality that is balanced between humor and seriousness and text-based communication over voice. A difference is the Swedish preference for direct in-app payment while German digital natives would select a redirection to a secondary payment provider (e.g. PayPal).

Full textAbstract:
The emerging health care culture of accountability for patient outcomes compounds problems for already overwhelmed clinicians struggling to fit everything entailed in complicated office visits into 15-minute appointments. Unprocessed frustrations tempt clinicians to use ineffective and outdated methods for trying to get their patients to comply or adhere to their care plans, undermining effective health care management. The intention of this project was to evaluate whether educating medical assistants in the health coaching method of motivational interviewing can improve the patient care approach while simultaneously assisting clinicians struggling with insufficient time. Several individual scheduling conflicts limited the target population into two primary care medical assistants and two auxiliary primary care office staff who voluntarily chose to learn the new approach. Guided by the adult learning theory, an educational lecture project was designed to capture the spirit of motivational interviewing through basic descriptions and strategies that will assist learners to focus on person-centered conversation skills, helping to balance both the needs of the patient and clinician. Following the education, participants filled out an anonymous post-lecture evaluation questionnaire to provide immediate feedback about learner understanding. Responses indicated the project met its stated objectives, and results showed the versatility of the motivational interviewing method which can be learned and effectively applied by health care workers from a wide range of professional backgrounds. Motivational interviewing is an innovative approach that utilizes therapeutic communication to promote behavior changes that lead to improved health of our communities and country.

Full textAbstract:
Companies across a wide range of business areas are working hard to fulfill users wishes to speak to digital voice assistants. The trend of replacing chatbots in favour for voice assistants carries a risk of companies not considering which applications will actually benefit from getting a voice user interface (VUI) resulting in poor user experience. This thesis aims to investigate which help desk support task will benefit from being implemented in a VUI. By following the Service Design methodology, research on the topic has been conducted and a prototype has been build and tested on a target audience. The results from a user study were evaluated and conclusions have been drawn about which tasks are best suited for being handled by a digital voice assistant. Two kinds of help desk tasks were evaluated in a user study to compared users experience of the current text based digital assistant with a prototype of a voice based assistant. The aim of the user study was to find which task would benefit from becoming voice based by looking at users acceptance level and over all experience. The results from the user study showed that employees who use the current text based assistant for help desk tasks, will not choose to speak to a digital voice assistant because they are happy with the service available today. However, employees who don’t use the current text based assistant, will find the digital voice assistant useful. It was also found that short executing tasks such as unlocking accounts, are a better fit for the VUI compared to longer interactions providing information. Two conclusions were drawn, peoples’ preferences are different, meaning that it should be possible to interact with both a text based and voice based assistant when performing help desk tasks. Secondly, the voice based assistant should be implemented as a function in the help desk phone queue instead of being implemented in a browser. Because the users argued that they would be more comfortable speaking to a phone then to a screen.Företag i alla branscher jobbar hårt för att uppfylla sina användaresönskan om att interagera med röstassistenter. Trenden att byta en chattbot mot en röstassistent medför en risk att företag inte tar hänsyn till huruvida en tjänst faktiskt drar nytta av att göras om till ett röstbaserat användargränssnitt, vilket kan resultera i en försämrad användarupplevelse. Denna uppsats undersöker vilka funktioner i en kundtjänst som skulle gagnas av att implementeras i ett röstbaserat användargr ̈anssnitt. Genom att använda Service Design modellens forsknings- och idé-genererings fas har en röstbaserad prototyp tagits fram och testats på målgruppen. Resultaten från användarstudien har utvärderats och slutsatser har formulerats. Två typer av kundtjänstfunktioner har undersökts i en användarstudie som jämfört användarnas upplevelse av den befintliga chatbotten och en röstassistentsprototyp. Målet med användarstudien var att definiera vilka kundtjänstfunktioner som skulle gynnas av att bli röstbaserade genom att titta på användarnas acceptansnivå och övergripande upplevelse. Resultaten visar att, användare som idag använder, och är nöjda med, chatbotten förmodligen inte kommer att ersätta denna med röstassistenten. Samtidigt som användaren som idag inte använder chatbotten kan tänka sig att använda röstassistenten istället för att ringa till kundtjänsten. En annan upptäckt från användarstudien var att funktioner som utför en uppgift, så som att låsa upp ett konto, passar bättre i ett röstbaserat sammanhang i jämförelse med när längre information ska förmedlas. Slutligen formulerades två slutsatser. För det första, olika personer har olika preferenser, det borde alltså vara möjligt att interagera med både chatbotten och röstassistenten för kundtjänstärenden. För det andra, röstassistenten borde implementeras som en plugin som användaren kan utnyttja när denne sitter i telefonkön till kundtjänsten snarare än en egen funktion i på den befintliga hemsida. Detta på grund av att användarna uttryckte att det är mer bekväma med att prata i telefon snarare än till en skärm.

Dessa uppgifter inkluderar att svara på frågor, hantera scheman, hemkontroll, spela musik och mycket mer. Eftersom digitala assistenter är relativt nya så finns det ett behov av mer kunskap om hur man kan skapa applikationer för plattformen.Rapporten ger kunskap om hur utvecklingsprocessen ser ut för en röststyrd ap- plikation till Google Assistant. Detta görs med en fallstudie som ger en inblick i de olika design- och arkitekturval som ingår i mjukvaruutvecklingen. Resultatet beskriver lämpliga konversationsmönster för röstgränssnitt i röststyrda applikationer och ett lämpligt arkitekturmönster för kodbasen. Med hjälp av studien drogs slutsatser om vilka begränsningar som finns hos röststyrda applikationer.Voice control and voice interpretation is an interface between users and computers that have become more common in commercial products. The interface is used in digital assistants, which is a software-based service designed to help users perform digital tasks. These tasks include answering questions, managing their schedules, home control, playing music and more. Because digital assistants are relatively new, there is a need for more knowledge about how to create applications for the platform.The report provides information on how the development process looks like for a voice-controlled application for Google Assistant. This is done by a case study that provides insight into the various design and architecture choices that are included in the software development. The result describes a suitable conversation pattern for voice interfaces in voice-controlled applications and an appropriate architecture for the codebase. The study draws conclusions about the limitations of voice-controlled applications.

Full textAbstract:
Background: The registered nurses specific area of competence is nursing care, which must be performed in a trusting relationship with the patient. Within perioperative care nurse anaesthetists, registered nurses and assistant nurses work with varied specific tasks to provide patient good care, before, during and after surgery. Sometimes they care for patients with advanced abdominal cancer, whose surgery is crucial for the prognosis of their illness. This means they care for patients directly before and directly after they receive their updated prognosis. Sometimes this surgery for advanced abdominal cancer is considered inoperable shortly after start of surgery, abdominal cancer is often detected at a late stage due to diffuse symptoms. The survival rate after surgery is often short, and palliative care is therefore often initiated. Aim: To describe nurse anaesthetists, registered nurses and assistant nurses experiences when caring for patients directly after surgery whose abdominal cancer was deemed inoperable. Method: Explorative qualitative studied design. Data collection, focus group discussions with nurse anaesthetists, registered nurses and assistant nurses. Analysed using qualitative content analysis. Results: The result is described with three overarching themes. Feeling of inadequacy whitch described the feeling of not wanting to lie, of identifying with patients of the same age, insufficient information and that body language can inadvertently transmit information. Creating strategies describes the difficulty in answering questions and the need for recovery. A feeling of increased security is about the opportunity to prepare and feeling that the conversation with the patient is facilitated. The three themes are based on eight underlying categories. Discussion: No previous research could be found, whitch may indicate that the research question of the study is unique. The use of focus groups as a method was experienced positively, but the prevailing pandemic has affected the possibility of including participants. The experiences of nurse anaesthetists, registered nurses, assistant nurses was shown to be similar, probably unintentially provide to the fact that all participants worked with perioperative care. Conclusion: Nurse anaesthetists, registered nurses and assistant nurses considered it challenging to care for patients with inoperable abdominal cancer. The main challenge was to care for the patients of same age and to respond to patients questions without inadvertently conveying information with body language.Bakgrund: Den legitimerade sjuksköterskans specifika kompetensområde är omvårdnad, vilken skall utföras i en förtroendefull relation till patienter. Inom perioperativ vård arbetar anestesisjuksköterskor, legitimerade sjuksköterskor och undersköterskor med olika specifika arbetsuppgifter för att ge patienter god omvårdnad inför, under och efter operation. Ibland vårdas patienter med avancerad bukcancer, vars operation är avgörande för sjukdomens prognos, vilket innebär att de vårdar patienter både direkt innan beskedet om prognos och direkt efter. Det händer att patienter som skall opereras för avancerad bukcancer, ibland bedöms inoperabla en kort tid efter att operationen påbörjats. Bukcancer upptäcks ofta i sent skede på grund av diffusa symtom. Överlevnaden efter operation bedöms i dessa fall kort, vilket betyder att palliativ vård ofta behöver initieras. Syfte: Att beskriva anestesisjuksköterskors, legitimerade sjuksköterskors och undersköterskors upplevelser av att vårda patienter direkt postopertivt vars operation avbrutits pga. inoperabel bukcancer. Metod: Explorativ kvalitativ studiedesign. Datainsamling, fokusgruppsdiskussioner med anestesisjuksköterskor, legitimerade sjuksköterskor och undersköterskor. Analys enligt kvalitativ innehållsanalys. Resultat: Resultatet beskrivs utifrån tre övergripande tema, Känsla av otillräcklighet, som handlar om att inte vilja ljuga, att jämnåriga patienter berör, om otillräcklig information och att kroppsspråket oavsiktligt kan överföra information. Skapa strategier beskriver svårigheten att bemöta frågor och behov av återhämtning och Känsla av ökad trygghet handlar om möjlighet att förbereda sig och en känsla av att samtalet med patienter underlättas. De tre tema baseras på åtta underliggande kategorier. Diskussion: Ingen tidigare forskning kunde hittas, vilket kan betyda att föreliggande studies forskningsfråga är unik.Fokusgruppsdiskussion som metod upplevdes positivt, men rådande pandemi anses ha påverkat möjligheten att inkludera ytterligare deltagare. Upplevelserna hos anestesisjuksköterskor, legitimerade sjuksköterskor och undersköterskor visade sig vara liknande, troligtvis relaterat till att samtliga deltagare arbetade med perioperativ vård. Slutsats: Anestesisjuksköterskor, legitimerade sjuksköterskor och undersköterskor upplevde att det var en utmaning att vårda patienter med inoperabel bukcancer. Utmaningen bestod främst i att vårda jämnåriga patienter och att bemöta frågor utan att med kroppspråket oavsiktligt förmedla information.

Le développement actuel, en TAO personnelle, d'environnements interactifs pour rédacteur monolingue conduit à modéliser des fonctions de documentation, d'autodocumentation, d'autoformation, de gestion de bases de connaissances personnelles, portant sur les propriétés linguistiques de la langue de travail. D'autre part, de nombreux Occidentaux se motivent pour la découverte et l'apprentissage autonome des idéogrammes utilisés à la fois en chinois, japonais et coréen écrits. Locuteurs ou scripteurs autochtones sont également intéressés par de tels composants. Dans ces contextes se situe notre contribution à la modélisation et au prototypage d'une base des propriétés lexicographiques des caractères chinois ― le projet «Apprentissage Assisté par Ordinateur des Caractères Chinois», dont les prototypes prennent l'acronyme CACAO. La base d'informations, structurée en hyperdocument, place l'utilisateur en situation d'exploration encyclopédique, lui permettant de se construire une vue progressive, différenciée, des propriétés des caractères: propriétés «hors-langue» (morphologie, sémantique universelle), propriétés «en-langue» ― spécifiques d'une langue, ici chinoise (phonétique, sémantique contextuelle, utilisations en composition…). Nous proposons un modèle conceptuel des propriétés des caractères à stocker dans la base de connaissances. La démarche retenue est celle d'un prototypage évolutif, en HyperCard. Une première maquette valide les options de l'interface-apprenant. Un prototypage en vraie grandeur (1026 caractères) affine ensuite certains choix fonctionnels. Des prototypages parallèles explorent également différentes vues (Base à Objets en LOOPS, SGBD sous Oracle, système à règles en Prolog) des fonctions principales: structuration de la base, navigation, recherche multicritère des caractères, observatoire de l'activité de l'utilisateur. Ce multiprototypage est aussi une contribution au développement d'environnements hétérogènes, multiplateforme, de production de logiciels didactiques. Nous souhaitons conduire sur CACAO des expérimentations didactiques, ouvertes sur la modélisation des comportements d'apprenants. Indépendamment du développement possible d'un produit à finalité didactique, le système réalisé constitue le socle applicatif d'une recherche sur les interfaces coopérants et les architectures d'assistants intelligents de découverte de connaissances

Full textAbstract:
The very first artificial satellite, Sputnik, was launched in 1957 marking a new era. Concurrently,
satellite mission operations emerged. These start at launch and finish at the end of mission, when
the spacecraft is decommissioned. Running a satellite mission requires the monitoring and control
of telemetry data, to verify and maintain satellite health, reconfigure and command the spacecraft,
detect, identify and resolve anomalies and perform launch and early orbit operations.
The very first chatbot, ELIZA was created in 1966, and also marked a new era of Artificial Intelligence
Systems. Said systems answer users’ questions in the most diverse domains, interpreting
the human language input and responding in the same manner. Nowadays, these systems are
everywhere, and the list of possible applications seems endless.
The goal of the present master’s dissertation is to develop a prototype of a chatbot for mission
operations. For this purpose implementing a Natural Language Processing (NLP) model for satellite
missions allied to a dialogue flow model. The performance of the conversational assistant is
evaluated with its implementation on a mission operated by the European Space Agency (ESA),
implying the generation of the spacecraft’s Database Knowledge Graph (KG).
Throughout the years, many tools have been developed and added to the systems used to monitor
and control spacecrafts helping Flight Control Teams (FCT) either by maintaining a comprehensive
overview of the spacecraft’s status and health, speeding up failure investigation, or allowing to easily
correlate time series of telemetry data. However, despite all the advances made which facilitate the
daily tasks, the teams still need to navigate through thousands of parameters and events spanning
years of data, using purposely built user interfaces and relying on filters and time series plots.
The solution presented in this dissertation and proposed by VisionSpace Technologies focuses on
improving operational efficiency whilst dealing with the mission’s complex and extensive databases.O primeiro satélite artificial, Sputnik, foi lançado em 1957 e marcou o início de uma nova era. Simultaneamente, surgiram as operações de missão de satélites. Estas iniciam com o lançamento e terminam com desmantelamento do veículo espacial, que marca o fim da missão. A operação de satélites exige o acompanhamento e controlo de dados de telemetria, com o intuito de verificar e manter a saúde do satélite, reconfigurar e comandar o veículo, detetar, identificar e resolver anomalias e realizar o lançamento e as operações iniciais do satélite. Em 1966, o primeiro Chatbot foi criado, ELIZA, e também marcou uma nova era, de sistemas dotados de Inteligência Artificial. Tais sistemas respondem a perguntas nos mais diversos domínios, para tal interpretando linguagem humana e repondendo de forma similar. Hoje em dia, é muito comum encontrar estes sistemas e a lista de aplicações possíveis parece infindável. O objetivo da presente dissertação de mestrado consiste em desenvolver o protótipo de um Chatbot para operação de satélites. Para este proposito, criando um modelo de Processamento de Linguagem Natural (NLP) aplicado a missoões de satélites aliado a um modelo de fluxo de diálogo. O desempenho do assistente conversacional será avaliado com a sua implementação numa missão operada pela Agência Espacial Europeia (ESA), o que implica a elaboração do grafico de conhecimentos associado à base de dados da missão. Ao longo dos anos, várias ferramentas foram desenvolvidas e adicionadas aos sistemas que acompanham e controlam veículos espaciais, que colaboram com as equipas de controlo de missão, mantendo uma visão abrangente sobre a condição do satélite, acelerando a investigação de falhas, ou permitindo correlacionar séries temporais de dados de telemetria. No entanto, apesar de todos os progressos que facilitam as tarefas diárias, as equipas ainda necessitam de navegar por milhares de parametros e eventos que abrangem vários anos de recolha de dados, usando interfaces para esse fim e dependendo da utilização de filtros e gráficos de series temporais. A solução apresentada nesta dissertação e proposta pela VisionSpace Technologies tem como foco melhorar a eficiência operacional lidando simultaneamente com as suas complexas e extensas bases de dados.

Throughout the times it has been witnessed a continuous evolution in the way people make
business transactions, across sectors. This has been highly influenced by technological
developments and the constant need for companies to adjust to their clients’ needs and
expectations. The retail sector has been no exception, evolving alongside innovation, and
adapting to new trends. One of its results is the emergence of conversational commerce, a new
form of commerce that combines the trend of communicating via instant messages and the use
of artificial intelligence, introducing virtual assistants to the retail context.
The aim of this study is to better understand the potentialities virtual assistants have in the
Portuguese retail context, amongst young adults. By identifying which of the dimensions of the
interaction with a retailer virtual assistant - "Cognitive Perception, Affective Engagement, and
Communication Quality" - have a significant impact on the expectation users create towards their
customer experience and how this is determinant to their patronage intentions towards the
retailer. A quantitative methodology was used to perform this investigation, with the
development of an introductory chatbot and an online survey, completed by 385 individuals
(Portuguese young adults, with ages ranging from 18 to 35, and that had access to the Facebook
Messenger app).
The Customer Experience Expectation was proven to have a significant impact on the
respondent' patronage intentions towards the virtual assistant and the retailer. However, only
the cognitive dimension of the virtual assistant was confirmed to significantly impact the
expectations on the customer experienceAo longo dos tempos, tem-se vindo a testemunhar uma evolução na forma como o comércio é feito nos vários setores de atividade. As empresas têm de se reinventar constantemente para satisfazer as necessidades e expectativas dos consumidores, que resultam dos avanços tecnológicos. O mesmo acontece no setor do Retalho, que tem vindo a inovar, acompanhando a tecnologia e as tendências dos consumidores. Um exemplo disto é o aparecimento da uma nova forma de comércio, o comércio conversacional. Este combina a tendência de comunicação via mensagens instantâneas com o desenvolvimento da inteligência artificial, introduzindo assistentes virtuais neste setor. O principal objetivo deste estudo prende-se com a investigação do impacto que a inclusão de um assistente virtual teria no setor do retalho interagindo com os jovens adultos portugueses. Para tal, procurou identificar-se quais as dimensões da interação com um assistente virtual - cognitiva, afetiva e comunicativa - que influenciariam as expectativas relativas à experiência de compra e consequentemente as intenções de uso e compra dos consumidores. Para a investigação foi utilizada uma metodologia quantitativa, com a criação de um "chatbot" informativo e de um questionário "online", ao qual responderam 385 portugueses com idades desde os 18 até aos 35 anos, com acesso ao Facebook Messenger. Neste estudo foi provado que as expectativas dos consumidores em relação à experiência de compra influenciam as suas intenções de uso (assistente virtual) e compra (retalhista). No entanto, apenas a dimensão cognitiva mostrou ter um impacto significativo na criação de expectativas relativas à experiência de compra.

Dissertação de Mestrado em Engenharia Informática apresentada à Faculdade de Ciências e TecnologiaA assistência humana tem sido fundamental para os serviços de suporte a clientes. Contudo, o aparecimento de chatbots trouxe uma nova forma de alcançar casos de uso que antes eram cumpridos por humanos. Estes agentes virtuais ainda não são 100% assertivos, sendo insuficientes na maior parte das tarefas mais complexas.O WIT Bot Engine é uma plataforma para criar, desenhar e lançar bots em canais de conversação, como o Facebook Messenger, vivendo lado a lado com todos os outros contactos e são capazes de atuar de diferentes formas, incluindo serviço de suporte a cliente. Ainda assim, este produto não providencia planos de salvaguarda para situações em que os bots não são capazes de resolver. Dado que os bots ainda não são capazes de ocupar o lugar dos agentes humanos nesta matéria, a combinação da versatilidade dos chatbots e da experiência dos agentes humanos pode ser a resposta para estes sistemas de assistência a clientes. O módulo da Dashboard de Assistência Humana está completamente integrado na restante plataforma que disponibiliza um largo espectro de formas para o agente humano intervir nas conversas em que os bots não conseguem satisfazer.Este novo módulo, o resultado deste estágio, torna a plataforma WIT Bot Engine numa solução híbrida, composta por agentes humanos e virtuais e disponibilizando formas para os seus utilizadores assistirem os seus bots.
Human assistance has been essential for customer support services. The arising of chatbots, however, brought a new way to accomplish use-cases that before have been satisfied by humans. These virtual agents are not 100% accurate yet, being insufficient in most of the more complex and not trivial tasks.WIT Bot Engine is a platform to create, build and deploy bots in communication channels, like Facebook Messenger, living side-by-side with every other contact and being able to perform plentiful tasks, including customer support. Still, WIT Bot Engine does not have safeguard measures to situations that bots are not able to solve.Since bots are not entirely able to take the human’s place in this subject yet, the combination of the versatility of chatbots and the expertise of human agents can be the answer to recent customer support services. The Human Assistance Dashboard is a fully integrated module of WIT Bot Engine platform that enables an extensive set of ways for the intervention of human agents in conversations which bots fail to satisfy.This new module, the result of this internship, turns WIT Bot Engine platform into a hybrid solution, composed by virtual and human agents and enabling ways for businesses to assist their bots.

Internship Report presented as the partial requirement for obtaining a Master's degree in Data Science and Advanced Analytics, specialization in Business AnalyticsArtificial intelligence is changing the way how businesses are affronting their day-to-day difficulties. Chatbots are the perfect demonstration of how simple tasks and queries such as customer support or sales metrics and reporting could be solved without human intervention. This project introduced a task-oriented chatbot framework for Spanish language in a Point-Of-Sale webpage. We applied Natural Language Processing (NLP) techniques such as NER and evaluated two supervised learning methods: (i) an Artificial Neural Network (ANN) and (ii) a Support Vector Machines (SVM) model to create a contextualized chatbot that classifies the user’s intention in a text conversation, allowing bidirectional human-to-machine communication. These intents could go from simple chitchatting to detailed reports, always providing a natural flow in conversation. The results using an augmented and balanced corpus suggested that ANN model performed statistically better than SVM. Additionally, a real-word scenario with a small-talk survey made to five users gave positive feedback about the quality of predictions. Finally, a software architecture using a PaaS computing service and an API framework was proposed to implement this dialog system in further works.

The purpose of the research is to explore social workers' listening skills pertaining to
listening as communication skill during an experimental social work interview.
The research methodology comprised unique application of a social work interview. A
sample of five participating social workers was invited to listen to a video recording of
a social work interview requesting them to identify information presented by the client
through observation and listening by applying a set of predetermined theoretical
conversation elements.
The participation and involvement of participating social workers during the listening
experiment was video recorded for subsequent evaluation.
The conclusion reached from research findings indicates that the unique approach
adopted by participating social workers' achieved mixed results towards hypothetic
assistance offered to the experimental client. The researcher recommends that social
workers be developed and trained in the art of maintaining effective listening skills
during social work interviews to improve assistance to clients.Social Work
