AAAI-06 will include a special technical track on Artificial Intelligence and the Web (http://www.cs.umbc.edu/aaai06/). This year's conference will Celebrate "Fifty Years of Artificial Intellligence" and be held at the Seaport Hotel and World Trade Center in Boston 16-20 July 2006. The deadline for submitting papers is 16 February 2006. The track is especially interested in receiving papers in two active research areas: (i) using text and language analysis to interpret and understand natural language text found on the web and (ii) developing and exploiting Semantic Web languages and systems that explicitly encode knowledge using languages such as RDF and OWL. Innovative papers in other areas describing research involving both AI and the Web are also encouraged. For details, see the track web site, http://www.cs.umbc.edu/aaai06/.
