Abstract—As information has been increasing enormously in the world, it is difficult to retrieve the proper information as per the user satisfaction. In our proposed work, document crawler is used for gathering and extracting information from the documents available from online databases and other databases. Since search space is too large, Genetic Algorithm (GA) is used to find out the combination terms. In the proposed document retrieval system, we extract the keywords from the document crawler and with these keywords GA generates combination terms. The proposed work is having three main features: First is to extract keywords and other information from the database by a document crawler. Second is to generate the combination terms using genetic algorithm. Third, results generated from the GA are applied to information retrieval system to generate better results. From the results obtained, the relevance of the documents are verified using evaluation measures namely precision and recall.
