As a result of its Logic Programming heritage, the system may also recursively interrogate other ontologies or data repositories, providing a semantic integration of multiple sources. The components required to behave as a SPARQL query engine are explained and examples of integration of deferent sources are shown - in particular, the case of multiple OWL ontologies is discussed. .<\/jats:p>","DOI":"10.2298\/csis0802039l","type":"journal-article","created":{"date-parts":[[2009,3,27]],"date-time":"2009-03-27T07:29:02Z","timestamp":1238138942000},"page":"39-62","source":"Crossref","is-referenced-by-count":0,"title":["Representing and querying multiple ontologies with Contextual Logic Programming"],"prefix":"10.2298","volume":"5","author":[{"given":"Nuno","family":"Lopes","sequence":"first","affiliation":[{"name":"National University of Ireland, Digital Enterprise Research Institute, Galway, Ireland"}]},{"given":"Cl\u00e1udio","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Universidade de \u00c9vora, Portugal"}]},{"given":"Salvador","family":"Abreu","sequence":"additional","affiliation":[{"name":"Universidade de \u00c9vora, Portugal"}]}],"member":"1078","container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:29:33Z","timestamp":1685348973000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02140802039L"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2008]]}},"URL":"https:\/\/doi.org\/10.2298\/csis0802039l","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008]]}}}
