Element Relationship: Exploiting Inline Markup for Better XML Retrieval

: With the increasing popularity of semi-structured documents (particularly in the form of XML) for knowledge management, it is important to create tools that use the additional information contained in the markup. Although research on textual XML retrieval is still in its early stages, many retrieval approaches and engines exist. The use of inline markup in these engines so far is very limited. We introduce the concept of element relationship and describe how it can improve similarity calculation. We illustrate our ideas with examples based on an existing document collection. 1 Textual XML Retrieval In traditional Information Retrieval (IR), a user has an information need and wants to obtain documents fulfilling that need from a document base [BYRN99]. The situation is essentially the same in retrieval on document-centric XML; one important difference is that documents are not assumed to be atomic units, that is, the retrieval engine should return the most specific fragments satisfy...
