Abstract

In this paper, we would like to represent our research in Natural Language Information Retrieval (NLIR) system using grammar analysis. In our system, the queries are small texts of description in natural language. The system tries to get searching conditions from these queries by grammar analyzing and searches for the expected documents. In many NLIR system, the descriptions are analyzed by either annotations[5] or predefined patterns[8]. These techniques can lead to miss-understanding the user's request and find inappropriate results. Therefore, the research in NLIR system focuses on understanding the user's descriptions in natural language by grammar analysis technique should be conducted to make found results more accurate.
