摘要：Increasing the relevance of the results of research tools remains a real challenge for users and researchers in the field of information retrieval. To overcome this problem, several studies have been conducted, mainly in the methods and techniques that focus on the treatment and the reformulation of queries, to meet the needs of the users. The purpose of this paper is to contribute to the improvement of approaches to reformulate queries by semantic enrichment based on definition sentences. Definitions and terminology have several features and components that can be used in information retrieval, especially in the enrichment of queries. The essential components of the definition sentences are generic and specific terms. Our approach consists of exploiting the definition sentences making use of their generic and specific terms.
