Intelligent Information Processing and Web Mining

This volume contains selected papers, presented at the international c- ference on Intelligent Information Processing and Web Mining Conference nd IIS:IIPWM'06, organized in Ustro? (Poland) on June 19-22 , 2006. The event was organized by the Institute of Computer Science of Polish Academy of Sciences, a leading Polish research institution in fundamental and applied research in the area of Arti?cial Intelligence (AI) and of Inf- mation Systems (IS), in cooperation with a number of scienti?c and business institutions. It was a continuation of a series of conferences on these subjects, initiated by Prof. M. D?browski and Dr. M. Michalewicz in 1992. The conference was addressed primarily to those who are active in - ti?cial Immune Systems (AIS) and other biologically motivated methods, Computational Linguistics (CL), Web technologies (WT), and Knowledge Discovery (KD), and all kinds of interactions between those ?elds. Thesubmitted paperscoverednewcomputing paradigms,amongothersin biologically motivated methods, advanced data analysis, new machine lea- ing paradigms, natural language processing, new optimization technologies, applied data mining using statistical and non-standard approaches. The - pers give an overview over a wide range of applications for intelligent systems: in operating systems design, in network security, for information extraction from multimedia (sound, graphics), in ?nancial market analysis, in medicine, in geo-science, etc. Though numerous papers have been submitted, only a fraction of them (about 40%) was accepted for publication in a rigorous reviewing process.
