Using rich document representation in XML information retrieval

Abstract

In this paper we present a method of document representation called Rich Document Representation (RDR) to build XML retrieval engines with high specificity. RDR is a form of document representation that utilizes single words, phrases, logical terms and logical statements for representing documents. The Vector Space model is used to compute index terms weight and similarity between each element and query. This system has participated in INEX 2006 and tested with the Content Only queries of the given collection. The results have been very weak but a failure analysis has revealed that it has been caused by an error in document processing which has produced inconsistent IDs and caused a mismatch between the IDs assigned to document elements such as single terms, phrases and logical terms. However similar experiment on INEX2004 collection yielded very good precision on high specificity task with s3e123 quantization. © Springer-Verlag Berlin Heidelberg 2007.
