Claim 13:
14. The system of claim 8, wherein the operations further comprise:
forming a communicative discourse tree from the updated discourse tree by matching each fragment that has a verb to a verb signature;
identifying that the text comprises an argument corresponding to a claim by applying a classification model trained to detect argumentation to the communicative discourse tree;
evaluating a consistency of the argument with respect to itself and with respect to a domain definition clause that is associated with a domain of the text by solving a logic system that comprises:
(a) a fixed part comprising a term of the claim and the domain definition clause, and
(b) a variable part comprising a set of defeasible rules from the communicative discourse tree and a fact from a communicative action of the communicative discourse tree; and

responsive to determining that the evaluated consistency is greater than a threshold, forming a textual response from the text and outputting the textual response to an external device.
