FactStatement Dataset

Overview

FactStatement is the foundational layer of FactNet, a cross-lingual, multi-layered fact knowledge graph. FactStatements are language-neutral, atomic fact units directly mapped from Wikidata statements, forming the core building blocks of the knowledge graph.

• core_id: Unique identifier for the fact statement
• subject_qid: Wikidata QID of the subject entity
• property_pid: Wikidata PID of the property
• value: Raw value from Wikidata
• value_qid: Entity QID if the value is an entity (otherwise null)
• normalized_value: Standardized representation of the value
• claim_hash: Standardized hash of subject|property|normalized_value|qualifiers
• qualifiers: Qualifier information (time, location, etc.)
• references: Source information
• rank: Wikidata rank (preferred, normal, deprecated)
• confidence: Computed confidence score

Usage

FactStatements are designed to be language-neutral representations of facts that can be linguistically realized through the FactSense layer and semantically grouped through the FactSynset layer.
