On the End-to-End Argument Validation System based on Communicative Discourse Trees
We formulate a problem of an assessment of argumentation validity based on rhetorical analysis of text. Argumentation structure can be detected in text in the form of discourse trees extended with edge labels for communicative actions. Extracted argumentation structureisrepresentedas a defeasible logic program and issubject to dialectical analysisto establish the validity of the arguments for the main claim being communicated. We evaluate the accuracy of argument mining and then argument validation as well as anoverall performanceof an end-to-end argumentation system.
