Merge Work

TODO: shorten redirects (what links to text retrieval).

Here is the content from Document retrieval that I will try and do my best to integrate.

Text retrieval is a branch of computerised information retrieval where the information is stored primarily in the form of text, and the user could retrieve any documents to which given keywords had been attached. Both indexing and searching were relatively skilled occupations.

The advent of full text searching made the job of the indexer redundant during the 1980s. Text databases moved from being large and centralised to local and personal, thanks to the personal computer and the CD-ROM.

Text retrieval is a critical area of study today, since it is the fundamental basis of all internet search engines.

Example: PubMed

The PubMed form interface features the "related articles" search which works through a comparison of words from the documents' title, abstract, and MeSH terms using a word-weighted algorithm. The details of this algorithm are explicated here [1].

Relationship to human indexing

The opening paragraph included "The advent of full text searching made the job of the indexer redundant during the 1980s" This is simply wrong, with a full explanation of why shown here http://jalamb.com/full_text_searches/ —Preceding unsigned comment added by Proindexer (talk • contribs) 10:57, 16 May 2009 (UTC)
