However, most knowledge bases are incomplete, which can cause many downstream applications to perform poorly because they cannot find the corresponding facts in the knowledge bases. In this paper, we propose an extraction and verification framework to enrich the knowledge bases. Specifically, based on the existing knowledge base, we first extract new facts from the description texts of entities. But not all newly-formed facts can be added directly to the knowledge base because the errors might be involved by the extraction. Then we propose a novel crowd-sourcing based verification step to verify the candidate facts. Finally, we apply this framework to the existing knowledge base CN-DBpedia and construct a new version of knowledge base CN-DBpedia2, which additionally contains the high confidence facts extracted from the description texts of entities. <\/jats:p>","DOI":"10.1162\/dint_a_00017","type":"journal-article","created":{"date-parts":[[2019,6,21]],"date-time":"2019-06-21T19:11:15Z","timestamp":1561144275000},"page":"271-288","update-policy":"https:\/\/doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":15,"title":["CN-DBpedia2: An Extraction and Verification Framework for Enriching Chinese Encyclopedia Knowledge Base"],"prefix":"10.3724","volume":"1","author":[{"given":"Bo","family":"Xu","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Donghua University, Shanghai 200051, China"}]},{"given":"Jiaqing","family":"Liang","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Data Science, School of Computer Science, Fudan University, Shanghai 200433, China"}]},{"given":"Chenhao","family":"Xie","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Data Science, School of Computer Science, Fudan University, Shanghai 200433, China"}]},{"given":"Bin","family":"Liang","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Data Science, School of Computer Science, Fudan University, Shanghai 200433, China"}]},{"given":"Lihan","family":"Chen","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Data Science, School of Computer Science, Fudan University, Shanghai 200433, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8403-9591","authenticated-orcid":true,"given":"Yanghua","family":"Xiao","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Data Science, School of Computer Science, Fudan University, Shanghai 200433, China"}]}],"member":"2026","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1145\/1242572.1242667"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-76298-0_52"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1145\/1376616.1376746"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-60045-1_44"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1145\/2806416.2806523"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.3233\/SW-140134"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-89704-0_23"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-32025-0_28"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1145\/3269206.3271804"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1145\/3269206.3271809"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1162\/neco.1997.9.8.1735"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1613\/jair.2433"},{"volume-title":"Proceedings of the 51st Annual Meeting of the Association for Computational Linguistics","year":"2013","author":"Nakashole N.","key":"ref19"},{"key":"ref20","first-page":"5998","volume-title":"Advances in Neural Information Processing Systems 30","author":"Vaswani A.","year":"2017"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-39200-9_18"}],"container-title":["Data Intelligence"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mitpressjournals.org\/doi\/pdf\/10.1162\/dint_a_00017","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,14]],"date-time":"2025-03-14T07:42:51Z","timestamp":1741938171000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.sciengine.com\/doi\/10.1162\/dint_a_00017"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2019,6]]}},"alternative-id":["10.1162\/dint_a_00017"],"URL":"https:\/\/doi.org\/10.1162\/dint_a_00017","relation":{},"ISSN":["2641-435X"],"issn-type":[{"type":"electronic","value":"2641-435X"}],"subject":[],"published":{"date-parts":[[2019,6]]},"assertion":[{"value":"2019-01-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-05-24","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2019-06-21","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
