TL;DR
Based on the document-centric view of XML, the query language XIRQL is presented, which integrates most IR-related features by using ideas from logic-based probabilistic IR models, in combination with concepts from the database area.
Abstract
Based on the document-centric view of XML, we present the query language XIRQL. Current proposals for XML query languages lack most IR-related features, which are weighting and ranking, relevance-oriented search, datatypes with vague predicates, and semantic relativism. XIRQL integrates these features by using ideas from logic-based probabilistic IR models, in combination with concepts from the database area. For processing XIRQL queries, a path algebra is presented, that also serves as a starting point for query optimization.

These methods are presented in the framework of a general query evaluation procedure using the relational calculus representation of queries, and nonstandard query optimization issues such as higher level query evaluation, query optimization in distributed databases, and use of database machines are addressed.

ACM Transactions on Information SystemsA probabilistic relational algebra for the integration of information retrieval and database systems
406 Citations1997Norbert Fuhr, Thomas Rölleke
The concept of vague predicates which yield probabilistic weights instead of Boolean values are introduced, thus allowing for queries with vague selection conditions and implements uncertainty and vagueness in combination with the relational model.
Subtopic structuring for full-length document access
330 Citations1993Marti A. Hearst, Christian Plaunt
It is argued that the advent of large volumes of full-length text, as opposed to short texts like abstracts and newswire, should be accompanied by corresponding new approaches to information access and a partition of the text into coherent multi-paragraph units that represent the pattern of subtopics that comprise the text.

The primary goal of this study is to promote an integration of methods and techniques for MIR by contributing a conceptual model that encompasses in a unified and coherent perspective the many efforts that are being produced under the label of MIR.

A model to query document databases by both their content and structure is presented, showing that it provides a good trade-off between expressiveness and efficiency.

This paper implemented the model and ran a series of experiments to show that, in addition to the added functionality, the use of the structural information embedded in SGML documents can improve the effectiveness of document retrieval, compared to the case where no such information is used.

It is shown that the theory provides a rule, the Dempster’s combination rule, that lowens the expression of the uncertainty with respect to parts of a document, and that is compatible with the iogica{ model developed by Chiaramella et al.
