CogNet: Bridging Linguistic Knowledge, World Knowledge and Commonsense Knowledge

In this paper, we present CogNet, a knowledge base (KB) dedicated to integrating three types of knowledge: (1) linguistic from FrameNet, which schematically describes situations, objects and events. (2) world YAGO, Freebase, DBpedia Wikidata, provides explicit about specific instances. (3) commonsense ConceptNet, implicit general facts. To model these different consistently, introduce three-level unified frame-styled representation architecture. integrate free-form with other structured knowledge, propose strategy that combines automated labeling crowdsourced annotation. At present, CogNet integrates 1,000+ semantic frames KBs, 20,000,000+ frame instances as well 90,000+ assertions KBs. All data can be easily queried explored on our online platform, free download in RDF format for utilization under CC-BY-SA 4.0 license. The demo are available at http://cognet.top/.
