Representative embodiments disclose mechanisms to validate statements made as part of a document creation or editing process. As the user edits or creates a document using a document creation/editing application, statements made in the document can be submitted to a validation service in a proactive or reactive manner. The statement validation service receives the statement, resolves any coreferences using a coreference resolution process. Once coreferences in the statement have been resolved and replaced, entities are resolved using an entity resolution process. Predicates are then resolved using a predicate resolution process. Entity-predicate pairs are then used to traverse a knowledge graph to extract information relevant to the statement. Suggested corrections are created from the extracted information and presented to the user via the document creation/editing application.
