摘要：XML retrieval has attracted more and more attention and many efforts on exploiting the available content and structural information have been made to improve retrieval system performance. This paper presents an approach of Reranking XML retrieval elements in which various methods are exploited including reranking the returned XML elements based on combining document and element scores and topics categorization by classifying the tags in the structural paths constraints expressed in their fields. The experiment results show that our method contributes to enhancing retrieval performance.
