Collaborative information services on Web 2.0 are used by Internet users to produce digital information resources, and to furnish the contents of the resources with their own keywords, so-called tags. This book deals with collaborative information services and folksonomies as a method of representing knowledge and a tool for information retrieval. Collaborative information services on Web 2.0 are used by Internet users not only to produce digital information resources, but also to furnish the contents of the resources with their own keywords, so-called tags. Whilst doing so the user is not required to comply with rules, as is necessary with a library catalogue. The amount of user-generated tags in a collaborative information service is referred to as folksonomy. Folksonomies allow users to relocate their own resources and to search for other resources. This book deals with collaborative information services and folksonomies both as a method of representing knowledge and a tool for information retrieval.

In Web 2.0 users not only make heavy use of Col-laborative Information Services in order to create, publish and share digital information resources - what is more, they index and represent these re-sources via own keywords, so-called tags. The sum of this user-generated metadata of a Collaborative Information Service is also called Folksonomy. In contrast to professionally created and highly struc-tured metadata, e.g. subject headings, thesauri, clas-sification systems or ontologies, which are applied in libraries, corporate information architectures or commercial databases and which were developed according to defined standards, tags can be freely chosen by users and attached to any information resource. As one type of metadata Folksonomies provide access to information resources and serve users as retrieval tool in order to retrieve own re-sources as well as to find data of other users. The book delivers insights into typical applications of Folksonomies, especially within Collaborative Information Services, and discusses the strengths and weaknesses of Folksonomies as tools of knowl-edge representation and information retrieval. More-over, it aims at providing conceptual considerations for solving problems of Folksonomies and presents how established methods of knowledge representa-tion and models of information retrieval can successfully be transferred to them.
