چکیده
RÉSUMÉ. La tâche de notre recherche est de fournir le contexte de recherche à un moteur de recherche, i.e. étendre une requête. Nous proposons une méthode d’expansion automatique de requêtes basée sur la proximité des termes. Elle estime l’importance des termes candidats selon la proximité des termes de la requête dans les premiers documents retrouvés. L’évaluation sur les collections TREC indique que la performance de la recherche est améliorée significativement.

Query expansion based on relevance feedback and latent semantic analysis
Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...
متن کاملQuery Expansion Approach Based On Ontology and Local Context Analysis
In information query process, query expansion can effectively resolve the problem related to low query efficiency caused by ambiguous short query terms. This study proposes a query expansion approach based on ontology and local context analysis. Ontology-based query expansion enables the addition of standardized descriptive information for search query, while local context analysis, through doc...
متن کاملImproving the Eeectiveness of Informational Retrieval with Local Context Analysis
Techniques for automatic query expansion have been extensively studied in information retrieval research as a means of addressing the word mismatch between queries and documents. These techniques can categorized as either global or local. While global techniques rely on analysis of a whole collection to discover word relationships, local techniques emphasize analysis of the top ranked documents...
متن کاملEvaluation of Different Query Expansion Techniques for Arabic Text Retrieval System
The word mismatch problem is fundamental to Information retrieval. Query expansion process helps to overcome this problem. Based on the Arabic corpuses, the comparisons between two query expansion techniques (global and local query) have been conducted to determine the query effectiveness. First one represents the local context analysis which represents a local method, while a global method was...
متن کاملCombining Global and Local Semantic Contexts for Improving Biomedical Information Retrieval
In the context of biomedical information retrieval (IR), this paper explores the relationship between the document’s global context and the query’s local context in an attempt to overcome the term mismatch problem between the user query and documents in the collection. Most solutions to this problem have been focused on expanding the query by discovering its context, either global or local. In ...
متن کاملA Hybrid Approach of Query Expansion for Vietnamese Query
The semantics of a user’s query plays an important role in supporting an Information Retrieval (IR), which returns results closer to the user's query. However, most of user’s queries sometimes do not fully reflect the semantics. Therefore, it is necessary to add semantics to the user’s query. The paper presents how to add semantics into a query in Vietnamese language using a hybrid method, whic...
