SummaryCommon-sense Argumentative Reasoning
Given a debate title, a claim and a reason choosea correct warrant to complete the argumentativereasoning chain (SemEval-2018 Task 12)
Motivation• External world knowledge is essential for reason-
ing comprehension•No shared task system focused on enriching mod-
els with external knowledge•Related work shows improvements for natural
language inference and question answering withsymbolic knowledge
Contributions• Explore external knowledge beyond lexical→WIKIDATA (fact knowledge about entities)→ FRAMENET (prototypical situations)!Both resources lead to a small improvement!More work needed on integration of multiple an-
notation types! Logic-based modeling of reasoning is missing

Can companies be trusted?
Corporations have only one goal : to make profit .Reason
They do not have to satisfy customers tomake a profit.
Warrant 1They have to satisfy customers to make aprofit.
Warrant 2
Companies can’t be trusted .Claim
Do police use deadly force too often?
Police use the excuse of fear for life to abuse use of force .Reason
The excuse is rarely warranted.Warrant 1
The excuse is sometimes warranted.Warrant 2
Police is too willing to use force.Claim
Results•We use the intra-warrant attention model from the dataset paper (Habernal et al., 2018)+Word embeddings are concatenated with FRAMENET and WIKIDATA embeddings
