However, outputting the entire solution set may be prohibitively expensive if it is too big. In this case, outputting a small, sufficiently diverse subset of the solutions would be preferable. This leads to the Diverse-version of the original enumeration problem, where the goal is to achieve a certain level d of diversity by selecting k solutions. In this paper, we look at the Diverse-version of the query answering problem for Conjunctive Queries and extensions thereof. That is, we study the problem if it is possible to achieve a certain level d of diversity by selecting k answers to the given query and, in the positive case, to actually compute such k answers.<\/jats:p>","DOI":"10.46298\/lmcs-21(1:9)2025","type":"journal-article","created":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T17:40:08Z","timestamp":1738086008000},"source":"Crossref","is-referenced-by-count":0,"title":["Diversity of Answers to Conjunctive Queries"],"prefix":"10.46298","volume":"Volume 21, Issue 1","author":[{"given":"Timo Camillo","family":"Merkl","sequence":"first","affiliation":[]},{"given":"Reinhard","family":"Pichler","sequence":"additional","affiliation":[]},{"given":"Sebastian","family":"Skritek","sequence":"additional","affiliation":[]}],"member":"25203","published-online":{"date-parts":[[2025,1,28]]},"container-title":["Logical Methods in Computer Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/lmcs.episciences.org\/15156\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/lmcs.episciences.org\/15156\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T17:40:08Z","timestamp":1738086008000},"score":1,"resource":{"primary":{"URL":"https:\/\/lmcs.episciences.org\/12493"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,28]]},"references-count":0,"URL":"https:\/\/doi.org\/10.46298\/lmcs-21(1:9)2025","relation":{"has-preprint":[{"id-type":"arxiv","id":"2301.08848v3","asserted-by":"subject"},{"id-type":"arxiv","id":"2301.08848v2","asserted-by":"subject"}],"is-same-as":[{"id-type":"arxiv","id":"2301.08848","asserted-by":"subject"},{"id-type":"doi","id":"10.48550\/arXiv.2301.08848","asserted-by":"subject"}]},"ISSN":["1860-5974"],"issn-type":[{"type":"electronic","value":"1860-5974"}],"subject":[],"published":{"date-parts":[[2025,1,28]]},"article-number":"12493"}}
