Count Information

We define count information as a type of information that captures the cardinality of a set of entities, directly as a count or as enumerations. Here, we have two examples sets of entities with the set cardinality, or as we alternatively call them “count” and the instances which enumerate the set. The cardinality and enumeration have been obtained from authoritative sources.

We can already notice some differences between the two sets in terms of how much and how precise information exists of the two sets.

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.
