  1. Intermediary Semantic Representation through Proposition Structures Gabriel Stanovsky, Jessica Ficler, IdoDagan and YoavGoldberg “Selfies may be used as passwords” Syntactic Abstraction Proposition Structure Semantic Scale Semantic Interpretation SRL • Modality Syntactic Parsing Full Semantic Interpretation DRTNeo-Davidsonian “The economy is going to slipinto recession” COND(IF) Open IE You are going to get more out of syntax, if you are willing to make an effort Proposition Structures “Stalin's joke sums up Obama's dilemma” “The company, Random House, doesn’t report its earnings” “Selfies can be used as passwords” Get the most semantics out of syntax Syntactic Abstraction Future Tense Markers • Canonicalization modality, tense, factuality, passive vs active, truth status • Implied Propositionspossessives, appositions, nominalizations, adjectives, conditionals Possessives • Apposition “The economy will slip into recession” Stalin has a joke & Obama has a dilemma Random House is a company Why Should We Use It? Soon! • Compared to dependency parse: • Making hidden semantics explicit and canonical • Removing syntactic clutter • Better starting point for semantic processing Down the Road
