RelationFactory: A Fast, Modular and Effective System for Knowledge Base Population

We present RelationFactory, a highly effective open source relation extraction system based on shallow modeling techniques. RelationFactory emphasizes modularity, is easily configurable and uses a transparent pipelined approach. The interactive demo allows the user to pose queries for whichRelationFactory retrieves and analyses contexts that contain relational information about the query entity. Additionally, a recall error analysis component categorizes and illustrates cases in which the system missed a correct answer.
