Models and Ontologies about Facts, Claims, and Statements

Semantic Web Interest Group,

Hello. I am recently thinking about large-scale knowledgebases which can notify interested end-users about events pertaining to the facts, claims, and statements in their published documents, e.g., as facts, claims, and statements relevant to end-users change, evolve, are updated, or as new and relevant fact-checking articles appear online. I am recently thinking about large-scale reactive knowledgebases and systems which process incoming data and documents and which can route individual event-related messages to, or aggregate these event-related messages into automatically-generated digests for, end-users (see also: [1]).

I wonder whether anyone might be interested in these topics and know of any relevant models or ontologies about facts, claims, and statements? For example: facts and statements can be claimed to be true by people and software systems; facts, claims, and statements can have provenance; facts, claims, and statements can be referred to in fact-checking documents; facts, claims, and statements can be logically interrelated; facts, claims, and statements can support and refute one another; facts, claims, and statements can be related to previously-occurring facts, claims, and statements as situations unfold or evolve…

Are there any existing models or ontologies about facts, claims, and statements?


Best regards,
