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 textKonversation 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.

Full textThe increasing popularity and enhanced capabilities of intelligent personal assistants, such as Google Assistant, Siri, and Alexa, have allowed them to disrupt in many fields, some of which are: customer service, banking, and tourism. 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.

Fuckner, Márcio. "A personal assistant for the enactment of business processes." Thesis, Compiègne, 2016. http://www.theses.fr/2016COMP2270/document.
Full textOver 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
Pecune, Florian. "Modélisation de la prise de décision d'un agent conversationnel animé en fonction de son attitude sociale." Electronic Thesis or Diss., Paris, ENST, 2016. http://www.theses.fr/2016ENST0054.
Full textTo 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 textKonversationsrobotar 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.
Beaver, Ian. "Automatic Conversation Review for Intelligent Virtual Assistants." Thesis, The University of New Mexico, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10816823.
Full textWhen 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.

Paisley, Lisa Nicole. "The Role of Conversation in How Educational Services Assistant Superintendents Lead Change." Thesis, Brandman University, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10749555.
Full textPurpose: 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 textIn 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

Full textThe 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

This in spite of strong tensions between the two neighbour states as well as their armed conflicts. Considering these questions, our study seeks to reveal different political and educative factors, which contribute towards generating the exchange programme and keeping it alive. We particularly question its purpose and functions according to the viewpoints of assistants, teachers and institutions

Full textFöretag 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.

Full textVoice 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.

Thesis, Ersta Sköndal Bräcke högskola, Institutionen för vårdvetenskap, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:esh:diva-9121.
Full textBakgrund: 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.

Full textO 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.

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.

Full textA 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.

Full textArtificial 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.
