In this context, resources are commonly retrieved by checking if each available resource description satisfies the given query. This approach becomes inefficient with the increase of available resources. We propose a method for improving the retrieval process by constructing a tree index through a new conceptual clustering method for resources expressed as class definitions or as instances of classes in ontology languages. The available resource descriptions are located at the leaf nodes of the index, while inner nodes represent intensional descriptions (generalizations) of their child nodes. The retrieval is performed by following the tree branches whose nodes satisfy the query. Query answering time may be improved as the number of retrieval steps may be O(log n) in the best case. <\/jats:p>","DOI":"10.1142\/s1793351x10001085","type":"journal-article","created":{"date-parts":[[2011,6,1]],"date-time":"2011-06-01T11:51:49Z","timestamp":1306929109000},"page":"453-486","source":"Crossref","is-referenced-by-count":2,"title":["DL-LINK: A CONCEPTUAL CLUSTERING ALGORITHM FOR INDEXING DESCRIPTION LOGICS KNOWLEDGE BASES"],"prefix":"10.1142","volume":"04","author":[{"given":"CLAUDIA","family":"D'AMATO","sequence":"first","affiliation":[{"name":"Computer Science Department, University of Bari, Via Orabona, 4 Bari, 70125, Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"STEFFEN","family":"STAAB","sequence":"additional","affiliation":[{"name":"Institute for Computer Science, University of Koblenz-Landau, Universit\u00e4tsstra\u00dfe, 1, Koblenz, 56070, Koblenz, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"NICOLA","family":"FANIZZI","sequence":"additional","affiliation":[{"name":"Computer Science Department, University of Bari, Via Orabona, 4 Bari, 70125, Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FLORIANA","family":"ESPOSITO","sequence":"additional","affiliation":[{"name":"Computer Science Department, University of Bari, Via Orabona, 4 Bari, 70125, Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","volume-title":"Handbook on Ontologies","author":"Arndt R.","year":"2009"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jal.2006.03.002"},{"key":"rf6","volume-title":"The Description Logic Handbook","author":"Baader F.","year":"2003"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-57155-8"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1145\/176567.176569"},{"key":"rf11","volume-title":"Symbolic Logic and Mechanical Theorem Proving","author":"Chang C.
