Conceptual Summaries as Query Answers

Abstract

In this paper we address an approach to retrieval where conceptual summaries are given as answers to queries. The idea is to restrict a general world knowledge ontology to a given set of concepts and thereby providing a structure, a so-called instantiated ontology, for navigation and further investigation of the concepts. Typically the restriction will be to the concepts appearing in a set of documents or an entire corpus. In this paper we are specifically concerned with the instantiated ontology as source for extracting summarizing concepts.
