A Bacterial Textual Processing and Retrieval System

Abstract

In this paper, a web-based bacteria textual processing and retrieval system is presented with the purpose to support biological researchers a unified retrieval access as well as to ease their data management. The system contains two main parts, namely, thesaurus construction module and retrieval module. Three new thesauri are built on the basis of statistical approaches and they are verified with real corpora to be useful for document indexing, categorization and retrieval. On the other hand the proposed unified retrieval module simplifies users’ access task to deal with various kinds of databases either at local sites or remote sites. It is also embedded with ranking function for relevance judgment as well as on- line information extractors, such as indexer, bacteria predictor and the pattern extractor, for data management. All these proposed methods can be easily adaptable to other domains.
