This system demonstration paper presents IRIS (Informal Response Interactive System), a chat-oriented dialogue system based on the vector space model framework. The system belongs to the class of examplebased dialogue systems and builds its chat capabilities on a dual search strategy over a large collection of dialogue samples. | IRIS a Chat-oriented Dialogue System based on the Vector Space Model Rafael E. Banchs Human Language Technology Institute for Infocomm Research Singapore 138632 rembanchs@ Haizhou Li Human Language Technology Institute for Infocomm Research Singapore 138632 hli@ Abstract This system demonstration paper presents IRIS Informal Response Interactive System a chat-oriented dialogue system based on the vector space model framework. The system belongs to the class of examplebased dialogue systems and builds its chat capabilities on a dual search strategy over a large collection of dialogue samples. Additional strategies allowing for system adaptation and learning implemented over the same vector model space framework are also described and discussed. 1 Introduction Dialogue systems have been gaining popularity recently as the demand for such kind of applications have increased in many different areas. Additionally recent advances in other related language technologies such as speech recognition discourse analysis and natural language understanding have made possible for dialogue systems to find practical applications that are commercially exploitable Pieraccini et al. 2009 Griol et al. 2010 . From the application point of view dialogue systems can be categorized into two major classes task-oriented and chat-oriented. In the case of task-oriented dialogue systems the main objective of such a system is to help the user to complete a task which typically includes booking transportation or accommodation services requesting specific information from a service facility etc. Busemann et al. 1997 Seneff and Polifroni 2000 Stallard 2000 . On the other hand chat-oriented systems 37 are not intended to help the user completing any specific task but to provide a means for participating in a game or just for chitchat or entertainment. Typical examples of chat-oriented dialogue systems are the so called chat bots Weizenbaum 1966 Ogura et al. 2003 .
