On Argumentation Analysis
For computational linguists, discourse analysis is mostly restricted to text organization and the forms of exchange in conversation. More attention is due to the analysis of argumentation proper, that is: the claim/proof core (claims, model description, explicit inferences, evidence, hypothesis formulation and testing), and its rhetorical supplements (irony; analogy,...). Argumentation analysis can render services in summarization, information extraction, information retrieval, critical reading, scientific communication, and decision making. I will present a draft notation for the mark-up of argumentation, and show ways to mark up texts automatically or semi-automatically.
