Multi-modal network-based assertion verification

A non-transitory computer-readable medium storing instructions which, when executed by a processing system including at least one processor, cause the processing system to perform operations, the operations comprising:

• obtaining a first content comprising human language via at least one computing network;
• identifying at least one assertion in the first content, wherein the identifying comprises applying an open information extraction process to create a representation of the at least one assertion as a first formal relation comprising a first binary relation;
• identifying one or more content sources containing at least one second content relating to the at least one assertion;
• determining whether the at least one second content relating to the at least one assertion corroborates or contradicts the at least one assertion, wherein the determining whether the at least one second content corroborates or contradicts the at least one assertion comprises:
• identifying at least a second assertion in the at least one second content;
• creating a representation of the at least the second assertion as a second formal relation;
• and
• determining whether the second formal relation comprises an affirmation of the first formal relation or a negation of the first formal relation;
• and
• presenting the first content with an indication of whether the at least one second content relating to the at least one assertion corroborates or contradicts the at least one assertion.
