Improving Query Expansion for Information Retrieval Using Wikipedia
Query expansion (QE) is one of the key technologies to improve retrieval efficiency. Many studies on query expansion with relationships from single local corpus suffer from two problems resulting in low retrieval performance: term relationships are limited and unlisted query terms have no expansion terms. To address these problems, relationships between terms captured from Wikipedia are superim...
متن کاملQuery Translation for Cross-lingual Information Retrieval using Wikipedia
In this paper the system WikiTranslate is introduced that performs query translation for cross-lingual information retrieval (CLIR) that only uses Wikipedia. Queries will be mapped to Wikipedia concepts and the corresponding translations of these concepts in the target language are used to create the final query. WikiTranslate is evaluated by searching with topics in Dutch, French and Spanish i...
متن کاملQuery Expansion for Web Information Retrieval
Information retrieval (IR) systems utilize user feedback for generating optimal queries with respect to a particular information need. However the methods that have been developed in IR for generating these queries do not memorize information gathered from previous search processes, and hence can not use such information in new search processes. Thus a new search process can not profit from the...
متن کاملQuery Expansion for Khmer Information Retrieval
This paper presents the proposed Query Expansion (QE) techniques based on Khmer specific characteristics to improve the retrieval performance of Khmer Information Retrieval (IR) system. Four types of Khmer specific characteristics: spelling variants, synonyms, derivative words and reduplicative words have been investigated in this research. In order to evaluate the effectiveness and the efficie...
متن کاملSemantic Query Expansion for Arabic Information Retrieval
Traditional keyword based search is found to have some limitations. Such as word sense ambiguity, and the query intent ambiguity which can hurt the precision. Semantic search uses the contextual meaning of terms in addition to the semantic matching techniques in order to overcome these limitations. This paper introduces a query expansion approach using an ontology built from Wikipedia pages in ...
