Comprehensive Study and Comparison of Information Retrieval Indexing Techniques

Abstract

Abstract-This research is aimed at comparing techniques of indexing that exist in the current information retrieval processes. The techniques being inverted files, suffix trees, and signature files will be critically described and discussed. The differences that occur in their use will be discussed. The performance and stability of each indexing technique will be critically studied and compared with the rest of the techniques. The paper also aims at showing by the end the role that indexing plays in the process of retrieving information. It is a comparison of the three indexing techniques that will be introduced in this paper. However, the details arising from the detailed comparison will also enhance more understanding of the indexing techniques.

Analysis on the use of Latent Semantic Indexing (LSI) for document classification and retrieval system of PNP files

“…The performance of a full-text search is applied here and the process of retrieving information usually begins with a query from a user into the system. Query is a formal statement indicating the need for particular information [5]. The relevance of available information is determined depending on the technique used with respect to the entered queries and the results given are based on their relevance to the queries.…”
