1. A method for determining argumentation in text, the method comprising:

  • accessing text comprising fragments;

    creating a discourse tree from the text, wherein the discourse tree comprises a plurality of nodes, each nonterminal node representing a rhetorical relationship between at least two of the fragments and each terminal node of the nodes of the discourse tree is associated with one of the fragments;

    matching each fragment that has a verb to a verb signature, thereby creating a communicative discourse tree;

    determining whether the communicative discourse tree represents text that comprises affective argumentation by applying, to the communicative discourse tree, a classification model trained to detect a presence of affective argumentation; and

    responsive to determining that the text comprises affective argumentation, accessing a response that corresponds to the text and outputting the response.
