The cost of obtaining high quality triples is high and the data sources are facing a serious problem of data sparsity, which may result in insufficient training of long-tail entities. However, unstructured text encoding entities and relational knowledge can be obtained anywhere in large quantities. Word vectors of entity names estimated from the unlabelled raw text using natural language model encode syntax and semantic properties of entities. Yet since these feature vectors are estimated through minimizing prediction error on unsupervised entity names, they may not be the best for knowledge graphs. We propose a two-phase approach to adapt unsupervised entity name embeddings to a knowledge graph subspace and jointly learn the adaptive matrix and knowledge representation. Experiments on Freebase show that our method can rely less on the labelled data and outperforms the baselines when the labelled data is relatively less. Especially, it is applicable to zero-shot scenario.<\/jats:p>","DOI":"10.1155\/2020\/4741963","type":"journal-article","created":{"date-parts":[[2020,8,25]],"date-time":"2020-08-25T23:31:29Z","timestamp":1598398289000},"page":"1-10","source":"Crossref","is-referenced-by-count":3,"title":["Representation Learning of Knowledge Graphs with Embedding Subspaces"],"prefix":"10.1155","volume":"2020","author":[{"given":"Chunhua","family":"Li","sequence":"first","affiliation":[{"name":"Software and Service Outsourcing College, Suzhou Vocational Institute of Industrial Technology, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuefeng","family":"Xian","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Suzhou Vocational University, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xusheng","family":"Ai","sequence":"additional","affiliation":[{"name":"Software and Service Outsourcing College, Suzhou Vocational Institute of Industrial Technology, Suzhou 215104, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2960-2051","authenticated-orcid":true,"given":"Zhiming","family":"Cui","sequence":"additional","affiliation":[{"name":"School of Electronics and Information Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1145\/219717.219748"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2015.2483592"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/tpami.2013.50"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1613\/jair.5013"},{"key":"11","first-page":"809","volume":"11","year":"2011","journal-title":"ICML"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1007\/s10994-013-5363-6"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-46523-4_30"},{"key":"32","first-page":"1137","volume":"3","year":"2003","journal-title":"Journal of Machine Learning Research"},{"key":"33","first-page":"2493","volume":"12","year":"2011","journal-title":"Journal of Machine Learning Research"}],"container-title":["Scientific Programming"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2020\/4741963.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2020\/4741963.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/sp\/2020\/4741963.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,8,25]],"date-time":"2020-08-25T23:31:35Z","timestamp":1598398295000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/sp\/2020\/4741963\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,25]]},"references-count":9,"alternative-id":["4741963","4741963"],"URL":"https:\/\/doi.org\/10.1155\/2020\/4741963","relation":{},"ISSN":["1058-9244","1875-919X"],"issn-type":[{"type":"print","value":"1058-9244"},{"type":"electronic","value":"1875-919X"}],"subject":[],"published":{"date-parts":[[2020,8,25]]}}}
