Message Validation Pipeline for Agents of the Internet of Everything

In the Internet of Everything environment, agents exchange messages, backing up and motivating their decisions. In this environment, validation of message validity, truthfulness, authenticity and consistency is essential. We formulate a problem of domain-independent assessment of argumentation validity based on rhetorical analysis of text. Argumentation structure is discovered in the form of discourse trees extended with edge labels for communicative actions. Extracted argumentation structures are then encoded as defeasible logic programs and are subject to dialectical analysis, to establish the validity of the main claim being communicated. We evaluate the accuracy of each step of this affect processing pipeline as well as overall performance.
