The focus of this paper is approaches to measuring similarity for application in connection
with query evaluation. Rather than only comparing at the level of words the issue here is to …

This paper introduces to the main objectives of the OntoQuery project, with the agenda of
developing theories and methodologies for content-based retrieval from text databases …

In this article, we introduce principles for ontology‐based querying of information bases. We
consider a framework in which a basis ontology over atomic concepts in combination with a …

This paper deals with a new approach to ontology-based QA in which users ask questions in
natural language to knowledge bases of facts extracted from a federation of Web sites and …

This paper concerns the motivation for and subsequently the analysis of proposed additions,
in the form of new operators, to a concept language Ontolog for use in querying a content …

This paper outlines a relation-logical compositional semantics for the meaning content of
nominals using formal ontologies as semantic domains. Prepositions are conceived as …

The aim of this paper is to devise measures for similarity for querying an information base,
that utilizes the knowledge represented in an ontology. The basis for this approach is an …

This paper describes ongoing work, aimed at producing a lexicon of prepositions, ie
relations denoted by prepositions, to be used for information retrieval purposes. The work is …

Question Answering (QA) systems (as QA track of the Text Retrieval conference (TREC-QA)
