What can Quantum Theory Bring to Information Retrieval?
In Proc. 19th International Conference on Information and
Knowledge Management, October 2010.
In this paper we describe and evaluate a quantum-inspired geometric
IR framework, where a user's informaton needs are represented as unit vectors
and documents as subspaces in a Hilbert space. Experiments show that this
approach can compete with standard IR methods like BM25 in an adhoc scenario,
with the potential to directly support different forms of user interactions
as well as different retrieval tasks like novelty and diversity search.

Supporting Polyrepresentation in a Quantum-inspired Geometrical
Retrieval Framework.
In Proceedings of the 2010 Information Interaction in Context
Symposium, pages 115-124, New Brunswick, August 2010. ACM.
We show on a conceptual basis how the principle of
polyrepresentation, which considers several forms of document context, can be
integrated in a quantum-inspired geometrical retrieval framework. Evidence
coming from several document representations is combined by means of the
tensor product, where dependencies between representations are modelled using
entanglement. Shortlisted for best paper award.

Probabilistic, Object-oriented Logics for Annotation-based Retrieval
in Digital Libraries.
In Michael Nelson, Cathy Marshall, and Gary Marchionini, editors,
Proc. of the 6th ACM/IEEE Joint Conference on Digital Libraries (JCDL
2006), pages 55-64, New York, 2006. ACM.
In this paper I specify POLAR, a logic-based probabilistic
object-oriented framework aimed at retrieval based on user annotations.
Integrating concepts from databases and information retrieval, POLAR supports
a wide range of fact, structure and content queries, exploiting annotations
as a document context. The evaluation shows performance gains in a
discussions search task.
