The book contains an up-to-date collection of contributions from around the world that cover the wide spectrum of problems related to the World Wide Web. These problems include: organization of Web resources, information retrieval including browsing and Web data mining. Particular emphasis has been put on the creative and innovative application of intelligent methods for effective operations on the Web (information retrieval, extraction, and interpretation). The methods involve but are not restricted to fuzzy logic, neural networks, intelligent clustering, intelligent agents, and expert systems; and operate on textual and - in some cases - multimedia-based Web databases.
