H.-M. Haav & J. F. Nilsson: Approaches to Concept Based Exploration of Information Sources, in W. Abrahamowicz & J. Zurada (eds), Knowledge Discovery for Business Information Systems, Kluwer (Int. Series in Engineeering and Computer Science vol. 600), 2000. ISBN 0-7923-7243-3. Discusses and compares two ways of achieving content-based search: One based on descriptions in relation to a formal ontology, one based on the so called concept analytic approach (devised by Wille and associates) relying on the notion of Galois connections in lattices.

P. Plaggio: "Parsing in OntoQuery - Experiments with LKB", in [Jensen & Skadhauge (eds.) 01]. This paper claims that unification-based parsers, and in particular the LKB parser, are good candidates for parsing nominal phrases in the OntoQuery project. It shows that the LKB formalism supports the definition of concept ontologies and semantic selectional restrictions associated with the concepts, in the form of feature structure types, and that these types can be used to produce semantic representations of nominal phrases in terms of concepts and semantic roles, pp. 89-102.
