We propose a new approach that relies on\n            <jats:italic>endogenous<\/jats:italic>\n            signals, namely, the correctness of factual information provided by the source. A source that has few false facts is considered to be trustworthy.\n          <\/jats:p>\n          <jats:p>The facts are automatically extracted from each source by information extraction methods commonly used to construct knowledge bases. We propose a way to distinguish errors made in the extraction process from factual errors in the web source per se, by using joint inference in a novel multi-layer probabilistic model.<\/jats:p>\n          <jats:p>\n            We call the trustworthiness score we computed\n            <jats:italic>Knowledge-Based Trust (KBT)<\/jats:italic>\n            . On synthetic data, we show that our method can reliably compute the true trustworthiness levels of the sources. We then apply it to a database of 2.8B facts extracted from the web, and thereby estimate the trustworthiness of 119M webpages. Manual evaluation of a subset of the results confirms the effectiveness of the method.\n          <\/jats:p>","DOI":"10.14778\/2777598.2777603","type":"journal-article","created":{"date-parts":[[2015,5,15]],"date-time":"2015-05-15T16:09:36Z","timestamp":1431706176000},"page":"938-949","source":"Crossref","is-referenced-by-count":120,"title":["Knowledge-based trust"],"prefix":"10.14778","volume":"8","author":[{"given":"Xin Luna","family":"Dong","sequence":"first","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evgeniy","family":"Gabrilovich","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Murphy","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Van","family":"Dang","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilko","family":"Horn","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Camillo","family":"Lugaresi","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaohua","family":"Sun","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Google Inc."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2015,5]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1456650.1456651"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/1376616.1376746"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/1052934.1052942"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-7552(98)00110-X"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/1277741.1277814"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/1806596.1806638"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.14778\/1920841.1921008"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.14778\/1687627.1687690"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.14778\/1687627.1687691"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/2623330.2623623"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.14778\/2732951.2732962"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.14778\/1687553.1687620"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.14778\/2535568.2448938"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.5555\/2283396.2283398"},{"key":"e_1_2_1_15_1","first-page":"413","volume-title":"WWW","author":"Gal\u00e1rraga L.
