Abstract:

As research in Artificial Intelligence (AI) advances, it is crucial to focus on having seamless communication between humans and machines in order to effectively accomplish tasks. Smooth human-machine communication requires the machine to be sensible and human-like while interacting with humans, while simultaneously being capable of extracting the maximum information it needs to accomplish the desired task. Since a lot of the tasks required to be solved by machines today involve the understanding of images, training machines to have human-like and effective image-grounded conversations with h

Abstract:

Prior to 2012 artificial intelligence, the study of intelligent agents, followed Moore’s law which states that compute is doubling every two years. Post 2012 it has been doubling every 3.4 months. However, intelligent agents are focusing on human language, and conversation is rarely developed for education. This study investigates a student’s perceived benefits and limitations of chatbots in higher education, by exploring the relative advantage, complexity, and compatibility of a different chatbot functionality. By interviewing students the authors could establish four different themes that pe

Abstract:

Embodied Conversational Agents (ECA) form part of a range of virtual characters whose intended purpose include engaging in natural conversations with human users. While works in literature are ripe with descriptions of attempts at producing viable ECA architectures, few authors have addressed the role of episodic memory models in conversational agents. This form of memory, which provides a sense of autobiographic record-keeping in humans, has only recently been peripherally integrated into dialog management tools for ECAs. In our work, we propose to take a closer look at the shared characteris

Abstract:

The aim of this work is to simplify access to information for citizens of the city of Brno and at the same time to innovate the way of communication between the citizen and his city. The problem is solved by creating a conversational agent - chatbot Kroko. Using artificial intelligence and a Czech language analyzer, the agent is able to understand and respond to a certain set of textual, natural language queries. The agent is available on the Messenger platform and has a knowledge base that includes data provided by the city council. After conducting an extensive user testing on a total of 76

Abstract:

Assessing a conversational agent’s understanding capabilities is critical, as poor user interactions could seal the agent’s fate at the very beginning of its lifecycle with users abandoning the system. In this thesis we explore the use of paraphrases as a testing tool for conversational agents. Paraphrases, which are different ways of expressing the same intent, are generated based on known working input by performing lexical substitutions and by introducing multiple spelling divergences. As the expected outcome for this newly generated data is known, we can use it to assess the agent’s robust

Abstract:

Now-a-days the chatbot development has been moving from the field of Artificial-Intelligence labs to the desktops and mobile domain experts. In the fastest growing technology world, most smartphone users spend major time in the messaging apps such as Facebook messenger. A chatbot is a computer program that uses messaging channels to interact with users using natural Languages. Chatbot uses appropriate mapping techniques to transform user inputs into a relational database and fetch the data by calling an existing API and then sends an appropriate response to the user to drive its chats.

Les chatbots sont connus pour leur interface facile à utiliser et ils ne nécessitent que l'une des capacités les plus innées des humains qui est l'utilisation du langage naturel.

Denna uppsats undersöker hur elever som använder ett digitalt läromedel i form av en virtuell lärmiljö för matematiklärande upplever denna lärmiljö. Dessutom undersöks elevernas prestation i lärmiljöns matematiska uppgifter. Skillnader mellan elever i olika årskurser samt elever som är matematiskt låg- eller högpresterande studeras. Matematisk prestation beskrivs utifrån Goods (1981) passivitetsmodell som innebär att lågpresterande elever är mindre risktagande i klassrums

Toutefois, l'annotation de données est connue pour être une tâche difficile en raison de sa complexité et sa subjectivité : elle nécessite par conséquent de solides compétences analytiques dans le but de modéliser les textes en intention de dialogue. De ce fait, la plupart des projets d'annotation choisissent de former les experts aux tâches d'analyse pour en faire des "super-experts".

Abstract:

In this exciting era of cognitive computing, conversational agents have a promising utility and are the subject of this thesis. Conversational agents aim to offer an alternative to traditional methods for humans to engage with technology. This can mean to reduce human effort to complete a task using reasoning capabilities and by exploiting context, or allow voice interaction when traditional methods are not available or inconvenient. This thesis explores technologies that power conversational applications such as virtual assistants, chatbots and conversational agents to gain a deeper underst

Abstract:

INTRODUCTION: Conversational agents are of great interest in the field of mental health, often in the news these days as a solution to the problem of a limited number of clinicians per patient. Until very recently, little research was actually done in patients with mental health conditions, but rather, only in healthy controls. Little is actually known if those with mental health conditions would want to use conversational agents, and how comfortable they might feel hearing results they would normally hear from a clinician, instead from a chatbot.
