A Knowledge-Based Approach to Warrant Induction
Patrick Saint‐Dizier · Frontiers in artificial intelligence and applications · 2018
This contribution outlines the diversity of warrants which can connect a claim and a justification. Opposite justifications can support a claim and vice versa: two opposite claims can be supported by the same justification. Since warrants are seldom explicit, this contribution introduces a conceptual model, based on telicity, to automatically induce the content of warrants. This model is evaluated on a corpus of user generated content on various topics. The grammatical and conceptual subtleties of warrants, depending on the argument they support, is also analyzed.
