Abstract
A method for performing fact verification includes receiving a document for verification; identifying and extracting, on the computer network, at least two named entities from the document for verification and associated information as metadata; identifying, off-chain, identifiers of relevant documents corresponding to each of the at least two named entities, the relevant documents being authenticated documents including one or more of the at least two named entities; identifying a predetermined number of relevant documents among the identified relevant documents based on a number of the at least two named entities present and a number of occurrences for each of the named entities; and determining whether the document to be verified is supported by the predetermined number of relevant documents.
