Multi-view Inference for Relation Extraction with Uncertain Knowledge.

Bo Li, Wei Ye, Canming Huang and Shikun Zhang. AAAI 2021, Regular Paper

We build and release a corpus named Probase_Desp, which contains high-quality descriptions of more than 15,000,000 entities and concepts. These descriptions are extracted from Wikipedia. Probase_Desp can be seen as the supplementary material for Probase, which provides a high-quality uncertain knowledge graph.

We apply Probase_Desp and uncertain knowledge graph on the sentence- and document-level relation extraction tasks and achieve significant improvements. Probase_Desp can serve as a valuable external knowledge resource for relation extraction and many other natural language processing tasks.
