Computing least common subsumers in description logics is an important reasoning service useful for a number of applications. As shown in the literature, it can, for instance, be used for similarity-based information retrieval where information retrieval is performed on the basis of the similarities of user-specified examples. In this article, we first show(More)
Due to the constantly growing number of information sources, intelligent information retrieval becomes a more and more important task. We model information sources by description logic (DL) terminologies. The commonalities of user-speci ed examples can be computed by the least common subsumer (LCS) operator. However, in some cases this operator delivers too(More)
Acknowledgments First of all I would like to thank Prof. Dr. Bernd Neumann. His encouraging comments and enthusiasm over the years shaped the whole work discussed in this monograph. Always emphasizing the importance of applications to demonstrate the adequacy of theoretical work, he suggested to particularly consider real-world problems. Thus, it is also(More)
