Mastering and effective exploration of the web environment needs new ideas, adaptation of known methods as well as application of sophisticated and robust technical implementations. Among new research directions present in relation to Web applications, a remarkable place is occupied by intelligent methods defining the topic of soft computing. This edited book includes reports from the front of diverse fields of the Web: application of artificial intelligence, design, information retrieval and interpretation, user profiling, security, engineering, etc. The material has been presented at the 5th Atlantic Web Intelligence Conference AWIC2007 held in Fontainbleau (France) and organized by Esigetel, Technical University of Lodz, and Polish Academy of Sciences.
