KRISTINA: a knowledge-based virtual conversation agent

Comunicació presentada a: The 15th International Conference, PAAMS 2017, celebrada a Porto, Portugal, del 21 al 23 de juny de 2017We present an intelligent embodied conversation agent with linguistic, social and emotional competence. Unlike the vast majority of the state-of-the-art conversation agents, the proposed agent is constructed around an ontology-based knowledge model that allows for exible reasoning-driven dialogue planning, instead of using prede ned dialogue scripts. It is further complemented by multimodal communication analysis and generation modules and a search engine for the retrieval of multimedia background content from the web needed for conducting a conversation on a given topic. The evaluation of the 1st prototype of the agent shows a high degree of acceptance of the agent by the users with respect to its trustworthiness, naturalness, etc. The individual technologies are being further improved in the 2nd prototype.The presented work is funded by the European Commission as part of the H2020 Programme, under the contract number 645012-RIA
