Dear all,

Next week, we'll have (finally) a CLS meeting again - and we'll make it a double bill! The theme is Learning Compositional Semantics, but the to talks approach it from quite different directions.

Sander Latour and Frank Smit will present their game-like environment used to generate a semantically-annotated corpus that might be use for learning. Phong Le will review the recent literature on machine learning of semantic parsers - many of them learning from semantically annotated corpora.

Date: April 25th
Location: ScP B0.209

Program:
16h00-16h45 Sander Latour & Frank Smit, Semantics Construction Environment for Non-Experts (abstract below)
(including 15 mins discussion)
16h45-17h15 Phong Le: Learning Semantic Parsing

Not really CLS, but interesting for many of you, so don't forget Tecumseh Fitch's SMART Cognitive Science Lecture this Friday, at 4pm in UT3.01 (Nieuwe Doelenstraat 16). See http://smartcognitivescience.wordpress.com

Semantics Construction Environment for Non-Experts

Sander Latour & Frank Smit

Abstract:

Over a one month period we've developed a series of online games that require the user to convert pictorial scenes to natural language sentences and vice versa. The result of these games was a parallel corpus of english sentences aligned with a structural description of the scenes. These structural descriptions cater for conversion to a desired formal semantic representation. The games were played by non-expert users in the Amazon Mechanical Turk environment, of which the corpus was evaluated manually on usefulness. The result of this project is a proof of concept that shows the potential of the game-based approach in creating corpora.
