Review of Indexing Techniques Applied in Information Retrieval

Abstract

<span>Indexing is one of the important tasks of Information Retrieval<span> that can be applied to any form of data, generated from the<span> web, databases, etc. As the size of corpora increases, indexing<span> becomes too time consuming and labor intensive, therefore,<span> the introduction of computer aided indexer. A review of indexing<span> techniques, both human and automatic indexing has been done<span> in this paper. This paper gives an outline of the use of automatic<span> indexing by discussing various hashing techniques including<span> fuzzy finger printing and locality-sensitive hashing. Two different<span> processes of matching that are used in automatic subject<span> indexing are also reviewed. Accepting the need of automatic<span> indexing in a possible replacement to manual indexing, studies<span> in the development of automatic indexing tools must continue<br /><br class="Apple-interchange-newline" /></span></span></span></span></span></span></span></span></span></span></span></span></span>
