This book constitutes the thoroughly refereed joint post-proceedings of five international workshops organized by the Japanese Society for Artificial Intelligence, held in Kitakyushu City, Japan, in June 2005, during the 19th Annual Conference JSAI 2005.

The volume starts with 5 award winning papers of the JSAI 2005 main conference that are presented along with the 40 revised full workshop papers, carefully reviewed and selected from the five co-located international workshops for inclusion in the volume. The workshop papers cover topics from areas such as logic and engineering of natural language semantics (LENLS 2005), learning with logics and logics for learning (LLLL 2005), agent network dynamics and intelligence (ANDI 2005), conversational informatics (CI 2005) and risk management systems with intelligent data analysis (RMSIDA 2005).
