A flexible model for retrieval of SGML documents

Abstract: In traditional information retrieval (IR) systems, a document as a whole is the target for a query. With increasing interests in structured documents like SGML documents, there is a growing need to build an LR system that can retrieve parts of documents, which satisfy not only content-based but also structure-based requirements.In this paper, we describe an inference-net-based approach to this problem. The model is capable of retrieving elements at any level in a principled way, satisfying certain containment … Show more

“…In this section we shall describe these two models and how they are used to retrieve document components from a document collection through probabilistic inference (see [2,3] for more details). Alternative probabilistic graphical models for structured information retrieval can also be found in the literature [6,7,9]. We assume a basic knowledge about graphical models.…”

“…Ribeiro and Muntz (1996), Indrawan et al (1994) and de Campos et al (2003a proposed other approaches also based on belief networks which were conceived for flat document retrieval. An extension of the Inquery model, designed to incorporate structural and textual information, has been proposed by Myaeng et al (1998). In this approach, a document is represented by a tree.…”

“…Crestani et al (2003aCrestani et al ( , 2003b propose an extension of the BN model of de Campos et al (2003a) for structured retrieval. Here the information goes in the reverse way compared to Myaeng et al (1998), i.e. it goes from term nodes up to the document node.…”
