Our model combines a regular link prediction model learned from a knowledge graph with word embeddings learned from a textual corpus. After training both independently, we learn a transformation to map the embeddings of an entity\u2019s name and description to the graph-based embedding space.In experiments on several datasets including FB20k, DBPedia50k and our new dataset FB15k-237-OWE, we demonstrate competitive results. Particularly, our approach exploits the full knowledge graph structure even when textual descriptions are scarce, does not require a joint training on graph and text, and can be applied to any embedding-based link prediction model, such as TransE, ComplEx and DistMult.<\/jats:p>","DOI":"10.1609\/aaai.v33i01.33013044","type":"journal-article","created":{"date-parts":[[2019,9,8]],"date-time":"2019-09-08T07:38:28Z","timestamp":1567928308000},"page":"3044-3051","source":"Crossref","is-referenced-by-count":56,"title":["An Open-World Extension to Knowledge Graph Completion Models"],"prefix":"10.1609","volume":"33","author":[{"given":"Haseeb","family":"Shah","sequence":"first","affiliation":[]},{"given":"Johannes","family":"Villmow","sequence":"additional","affiliation":[]},{"given":"Adrian","family":"Ulges","sequence":"additional","affiliation":[]},{"given":"Ulrich","family":"Schwanecke","sequence":"additional","affiliation":[]},{"given":"Faisal","family":"Shafait","sequence":"additional","affiliation":[]}],"member":"9382","published-online":{"date-parts":[[2019,7,17]]},"container-title":["Proceedings of the AAAI Conference on Artificial Intelligence"],"original-title":[],"link":[{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/4162\/4040","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/download\/4162\/4040","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T07:30:24Z","timestamp":1667806224000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.aaai.org\/index.php\/AAAI\/article\/view\/4162"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,17]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2019,7,23]]}},"URL":"https:\/\/doi.org\/10.1609\/aaai.v33i01.33013044","relation":{},"ISSN":["2374-3468","2159-5399"],"issn-type":[{"value":"2374-3468","type":"electronic"},{"value":"2159-5399","type":"print"}],"subject":[],"published":{"date-parts":[[2019,7,17]]}}}
