3 A tag is a (relevant) keyword or term associated with or assigned to a piece of information (a picture, a geographic map, a blog entry, a video clip etc.), thus describing the item and enabling keyword- based classification and search of information…….keyword or term Tags are usually chosen informally and personally by item author/creator or by its consumer/viewers/community (Wikipedia…)

4 An index term or descriptor in Information Retrieval is a term that captures the essence of the topic of a document.Information Retrieval It is used as keyword to retrieve documents in an information system, for instance a catalog or a search engine מאגרי מידע סתם כבר לא דוגמה (Wikipedia….)

13 Tagging is manual indexing instead of automatic indexing. Ironically a focus of research is again on automatic systems that do data mining in tagging data

14 Controlled vocabularies are subsumed as knowledge organization systems (KOS) ]]These systems have been studied and developed in library and information science for more then 100 years. Popular examples are the Dewey Decimal Classification, Ranganathans faceted classification, and the first thesauri in the 1960s.

15 Beginning with the 1950s library and information science has lost its leading role in the development of information retrieval systems and a rich variety of KOS has come into existence.
