Abstract

Retrieval of relevant documents from a large document collection is a challenging task. Document Retrieval is concerned with indexing and retrieving documents provided in a document collection. Documents are represented by document descriptors which are defined as terms or keywords extracted from the textual documents. Formulating an optimal query with a set of document descriptors involves searching a huge search space for the better permutation and combination of terms. As Genetic Algorithm is well suited for searching huge search spaces, in this paper, a two stage method is proposed for efficient information retrieval system using genetic algorithm. In our proposed method, Genetic Algorithm generates the best combination terms from a set of the document descriptors.
