Title:

Parsing Scoped Meaning Representations

Abstract:

In this talk I will present a new corpus of (short) texts annotated with formal meaning representations.  Using a parallel corpus, the resource is developed not only for English, but also for Dutch, German and Italian. The meaning representations comprise logical symbols (boolean and comparison operators) and non-logical symbols.  The non-logical symbols are completely grounded in WordNet concepts and VerbNet-style roles.  I will contrast two methods for semantic parsing on this corpus: a traditional technique using a categorial grammar and lambda-calculus, and an ultra-modern way using a (surprise, surprise) neural network. Guess which one performs better!
