The hidden Web (or invisible Web or deep Web) is the name given to pages on the World Wide Web that are not indexed by search engines. It consists of pages which are not linked to by other pages, such as dynamic Web pages based on responses to database queries. The deep Web also includes sites that require registration or otherwise limit access to their pages.

Abstract
The evolution of Web information is of utmost importance in the design of good Web Information Systems applications. New emerging paradigms, like the Semantic Web, use ontologies for describing metadata and are defined, in part, to aid in Web evolution. In this chapter, we survey techniques for ontology evolution. After identifying the different kinds of evolution with which the Web is confronted, we detail the various existing languages and techniques devoted to Web data evolution, with particular attention to Semantic Web concepts, and how these languages and techniques can be adapted to evolving data in order to improve the quality of Web Information Systems applications.
