In this context, we propose a method to substantially reduce the size of these graphs, allowing us to concentrate on the most relevant sections of the graph for a specific application or context. We define the notion of context graph as an extract from one or more general knowledge bases (such as DBpedia, Wikidata, Yago) that contains the set of information relevant to a specific domain while preserving the properties of the original graph. We validate the approach on a DBpedia excerpt for entities related to the Data&amp;Mus\u00e9e project and the KORE reference set according to two aspects: the coverage of the context graph and the preservation of the similarity between its entities. The results show that the use of context graphs makes the exploitation of large knowledge bases more manageable and efficient while preserving the features of the initial graph.<\/jats:p>","DOI":"10.3233\/ssw240023","type":"book-chapter","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T07:46:24Z","timestamp":1726472784000},"source":"Crossref","is-referenced-by-count":0,"title":["Towards Efficient Exploitation of Large Knowledge Bases by Context Graphs"],"prefix":"10.3233","author":[{"given":"Nada","family":"Mimouni","sequence":"first","affiliation":[{"name":"Center for Studies and Research in Computer Science and Communication, CNAM Paris"}]},{"given":"Jean-Claude","family":"Moissinac","sequence":"additional","affiliation":[{"name":"LTCI, T\u00e9l\u00e9com Paris, Institut polytechnique de Paris"}]}],"member":"7437","container-title":["Studies on the Semantic Web","Knowledge Graphs in the Age of Language Models and Neuro-Symbolic AI"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SSW240023","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T07:46:25Z","timestamp":1726472785000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SSW240023"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,9,11]]},"ISBN":["9781643685373"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/ssw240023","relation":{},"ISSN":["1868-1158","2215-0870"],"issn-type":[{"type":"print","value":"1868-1158"},{"type":"electronic","value":"2215-0870"}],"subject":[],"published":{"date-parts":[[2024,9,11]]}}}
