The purpose of the NECA project (http://www.oefai.at/ NECA/) is to develop a platform for the implementation of emotional conversational agents for Web-based applications. The users watch embodied conversational agents engage in verbal and nonverbal interaction in virtual "locations" on the internet. In the demonstrators, eShowroom and Socialite, two such "locations" are realized. While in the first project year the core techniques, programs and resources to enable the generation of animated conversation in web-based applications have been developed and implemented, the second project year is dedicated to the refinement of the system modules and the enhancement of the functionality of the demonstrators, with a focus on affective reasoning, and verbal and nonverbal realization of expressive behavior. The runtime of the project is 30 months. In the following we give an introduction to the demonstrators, followed by an overview of the NECA architecture, and then describe aspects of emotion modelling in NECA.
