Count Information
Cont information is the relation between an entity and a set of entities that can be expressed individually, as X is an employee of Z, Y is an employee of Z or as a cardinality Z has N employees. Identifying such information in text and knowledge bases (KBs) and linking the two variants can
- identify incomplete entity enumerations
- ground counts in representative entities
- identify KB inconsistencies
- enhance downstream tasks like search and question answering
Most research focus on numerical facts without joining the dots between numerical facts specifying cardinal information and their corresponding entity-to-entity grounding facts. Popular general-purpose KBs have limited ability to recognize such predicates.
