Texto completo da fonteIn this thesis we deal with the problem of the synthesis of assistance models dedicated to the support of help systems based on natural language interaction with users of computer applications. 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

Texto completo da fonteKonversationsrobotar 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.

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.

Fuckner, Márcio. "A personal assistant for the enactment of business processes". Thesis, Compiègne, 2016. http://www.theses.fr/2016COMP2270/document.
Texto completo da fonteOver 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

Texto completo da fonteUsually, the task of annotation, used to train conversational assistants, relies on domain experts who understand the subject matter to model. However, data annotation is known to be a challenging task due to its complexity and subjectivity. Therefore, it requires strong analytical skills to model the text in dialogue intention. As a result, most annotation projects choose to train experts in analytical tasks to turn them into "super-experts". In this thesis, we decided instead to focus on the real knowledge of experts by proposing a new annotation method based on Interactive Clustering. This method involves a Human-Machine cooperation, where the machine performs clustering to provide an initial learning base, and the expert annotates MUST-LINK or CANNOT-LINK constraints between the data to iteratively refine the proposed learning base. Such annotation has the advantage of being more instinctive, as experts can associate or differentiate data according to the similarity of their use cases, allowing them to handle the data as they would professionally do on a daily basis. During our studies, we have been able to show that this method significantly reduces the complexity of designing a learning base, notably by reducing the need for training the experts involved in an annotation project. We provide a technical implementation of this method (algorithms and associated graphical interface), as well as a study of optimal parameters to achieve a coherent learning base with minimal annotation. We have also conducted a cost study (both technical and human) to confirm that the use of such a method is realistic in an industrial context. Finally, we provide a set of recommendations to help this method reach its full potential, including: (1) advice aimed at framing the annotation strategy, (2) assistance in identifying and resolving differences of opinion between annotators, (3) rentability indicators for each expert intervention, and (4) methods for analyzing the relevance of the learning base under construction. In conclusion, this thesis provides an innovative approach to design a learning base for a conversational assistant, involving domain experts for their actual knowledge, while requiring a minimum of analytical and technical skills. This work opens the way for more accessible methods for building such assistants

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.

Texto completo da fonteThe goal of the thesis is to evaluate new forms of Human-Computer Interaction. More precisely, the general set of themes of this work, divided into two parts at aims implementing and evaluating the contribution of Embodied Conversational Agent (ECAs) and of adaptive interfaces for the use of software. Thus, behaviours and reactions of users are collected using ergonomic methods and eye-tracking technologies. An experimental approach was adopted in order to evaluate the contribution of each part. For that, participants (student of bachelor's degree) handled a software of animation's creation which was unknown for them (Flash) in order to carry out three scenarios. Throughout their exploration of the software, participants were accompanied by a help system. In the first experiment an ECA (provided by FT R & D) enunciate help messages; in the second one a adaptive system (detection of intention and evolution according to knowledge) was used. The various studies carried out show that the two innovations employed were perceived positively by the majority of the participants. They showed in addition that a ECA has a reassuring effect and that it can probably be used in first experiences with a software. For the adaptive system, the fact that the system evolves in an autonomous way did not disturb the participants, but hardly improves the performances

Notwithstanding, the application of intelligent personal assistants for training and learning of professional workers has been limited and not well researched. This document will validate the proposal of a solution for the continuous training and learning of the medical visitors on the information of the medications using a voice-based conversation agent. This will allow pharmaceutical sales representatives to ask the agent about the properties of the drugs and conduct frequent reviews of the information available to verify their knowledge. This validation will be carried out through the monitoring and application of a research methodology focused on the existing solutions and architectures that provide a basis to start the development of the project.

Texto completo da fonteKonversation 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.
Cabrera, Paraiso Emerson. "Icai : une interface conversationnelle pour une aide intelligente". Compiègne, 2005. http://www.theses.fr/2005COMP1590.
Texto completo da fonteThis thesis concerns the design of a conversational interface for personal assistant agents. We studied the typical user interface used in personal assistants. We conclude that conversational interfaces are the one especially suitable for personal assistants. To design the conversational interface, we took in account several constraints related to the agent itself and the potential applications. As the result of this approach we expect to improve the quality of assistance and to reduce the user's cognitive load. Ln this thesis we present a new concept called ICAI: A Conversational Interface for an Intelligent Assistance. An ICAI is the result of the conjunction of a conversational spoken natural language mechanism and an intelligent management of such mechanism, enabling a cooperative dialogue between the user and the assistant agent. Our approach is based on ontologies that allow us to interpret messages from human and artificial agents

Texto completo da fonteTo 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

Texto completo da fonteThis thesis is part of a multidisciplinary context on the border between the domains of the ambient intelligence, the human-machine interaction and the conversational agents. We study the problem of contextual proactive assistance in the course of the ambient computing. In this regard, our challenge is to provide to the user who wish have a virtual assistant, a proactive services which can communicate according to the user’s context. However proactive ambient intelligence, or contextual proactive assistance, did not follow an important development as reactive ambient intelligence where the user must explicitly express their needs. This is why the objective of this CIFRE thesis is to study and evaluate the concept of contextual proactive assistance through the implementation of an online conversational agent named X-CAMPUS. This acronym stands for eXtensible Proactive Multichannel Conversational Agent for Ubiquitous Services. This system aims to assist the user in their daily tasks thanks to its ability to perceive the state of the environment and interact effectively according to user’s needs (weather, TV programs, etc.). We conducted an experimental study to investigate the interest of X-CAMPUS and evaluate the satisfaction that it provides to users. We describe quantitative and qualitative results of this study obtained through a set of scenarios using different parameters of interaction (multimodal, multi-channels, behavior reactive/proactive agent, type of sensors, context mono/multi-user…)

Texto completo da fonteO 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.

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.

Texto completo da fonteArtificial 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.

This project presents a technological solution for the selfcare of elderly people with type 2 diabetes, in which an avatar with an anthropomorphic representation and artificial intelligence are incorporated. The main goal is to fill a gap in the lack of follow-up between face-to-face diabetes medical appointments, responding to the patient's daily needs by: i) motivating him/her to practice physical activity, with plans adapted to his/her limitations; ii) advising on his/her food choices and meal planning; and iii) reminding him/her to take the medication prescribed by health professionals. The assistant will respond according to the users’ motivation, congratulating him/her on the steps already taken and promoting the continuation of a ‘good job’ by proposing new challenges. This system is available for tablet devices. The development of the solution has been followed by tests with real patients of the target group and health professionals in health centers in the Lisbon area and in Escola Superior de Enfermagem de Lisboa (ESEL).

Texto completo da fonteAo 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.
