An Exponentiation Method for XML Element Retrieval

Abstract EN

XML document is now widely used for modelling and storing structured documents.

The structure is very rich and carries importantinformation about contents and their relationships, for example, e-Commerce.

XML data-centric collections require query terms allowing users to specifyconstraints on the document structure; mapping structure queries and assigning the weight are significant for the set of possibly relevant documentswith respect to structural conditions.

In this paper, we present an extension to the MEXIR search system that supports the combinationof structural and content queries in the form of content-and-structure queries, which we call the Exponentiation function.

It has been shownthe structural information improve the effectiveness of the search system up to 52.60% over the baseline BM25 at MAP.
