Papers about Human's perception of Agent

Demand for conversational interfaces is great and growing, especially for online commercial applications. Creating such interfaces so that the information is provided is accurate, believable and trusted is a complex engineering task. Various studies into how users react socially to an interface have shown that it is possible to improve the usability and general attraction of an interface by carefully implementing an appropriate personality. These findings are taken and applied to a true, reactive, real... Read more

This paper presents the evolution description and relevance of IVTE- Intelligent Virtual Teaching Environment project in terms of Artificial Intelligence and Artificial Intelligence in Education field. Furthermore, it describes the importance of Multi-agents modeling used in the IVTE software and also gives emphasis in the Cognitive Agent Model represented by an Animated Pedagogical Agent. The purpose of IVTE software is to educate children to preserve the environment. The IVTE software is implemented with Multi-agent (MAS) and... Read more

Research on embodied conversational agent interfaces has produced widely divergent results. We suggest that this is due to insufficient consideration of key factors that influence the perception and effectiveness of agent-based interfaces. Thus, we propose a framework for the evaluation of conversational agent interfaces that can systematize the research. The framework emphasizes features of the agent, characteristics of the user, and the task the user is performing. We have conducted experiments within this framework. The first study manipulated the agent's... Read more

This paper presents a preliminary evaluation of Alice, a chatterbot designed in order to elicit anthropomorphic attributions and emotional reactions from those who chat to ‘her’. The analysis is based on both transcripts of the interaction and user comments collected in a focus group. Results suggest that the introduction of explicit anthropomorphism in Human-Computer Interaction (HCI) is a complex phenomenon, which could generate strong negative reactions from the part of the user. The finding also... Read more

This article describes Artificial Life, Inc.’s WebGuide, an intelligent software bot that helps users navigate a Web site using natural language. The article describes the technology behind ALife-WebGuide, discusses some of the issues involved in commercialization of this type of user interface, and summarizes possible enhancements for future versions of this product.

Project COGITO aims at an agent-based interface for B-to-C applications that is not merely re-active to some user request, but pro-active and capable of engaging in a goal-directed conversation with the user, e.g., by taking the initiative to recommend new products. The approach combines content-based filtering, where user profiles are generated based on content features extracted from documents that users find relevant, with collaborative filtering which clusters users according to their...
