Minimized Models and Grammar-Informed Initialization for Supertagging with Highly Ambiguous Lexicons
13 years 5 months ago
We combine two complementary ideas for learning supertaggers from highly ambiguous lexicons: grammar-informed tag transitions and models minimized via integer programming. Each st...
