World Wide Web (WWW) provides interlinked hypertext documents (Web pages) that may contain text, images, videos, and other multimedia. WWW is growing at a remarkable rate and finding appropriate information can therefore be challenging. Web information retrieval deals with the search for documents, for information within documents and for metadata about documents, as well as that of searching databases in the WWW. Web information retrieval is an interdisciplinary science and deals with this challenge by exploiting various information technologies and computational intelligence approaches to design the next generation of web-information retrieval technologies.

"Web Intelligence explores the impact of artificial intelligence and advanced information technologies representing the next generation of Web-based systems, services, and environments, and designing hybrid web systems that serve wired and wireless users more efficiently. Multimedia and XML-based data are produced regularly and in increasing way in our daily digital activities, and their retrieval must be explored and studied in this emergent web-based era. 'Emergent Web Intelligence: Advanced information retrieval' provides reviews of the related cutting-edge technologies and insights.It is valuable companion and comprehensive reference for undergraduate and postgraduate students who are taking a course in Web intelligence and need to study current concepts of retrieval of multimedia and XML-based data, developers who need to implement advanced search engine and make benefit of web intelligence technologies, researchers who desire to understand exiting approaches, pin down their limits, and identify several future directions.The book is organized in self-contained chapters to provide greatest reading flexibility."
