Abstract

The focus in this article is on the use of structural hints to increase the retrieval performance of models for structured document retrieval. Based on an effective model for structured document retrieval for ‘content only’ queries, two extensions are defined that allow the retrieval model to include structural hints provided by the user into the retrieval process. The underlying hypothesis states that if the user is capable of providing structural clues, besides the content-based criteria of his/her information need, the retrieval performance can be increased. To test this hypothesis the two extensions are evaluated using a selection of the retrieval tasks defined for the INEX 2005 Ad-hoc track.
