Lexical and Grammatical Inference

• Tom Armstrong

Children are facile at both discovering word boundaries and using those words to build higher-level structures in tandem. Current research treats lexical acquisition and grammar induction as two distinct tasks; doing so has led to unreasonable assumptions. State-ofthe-art unsupervised results presuppose a perfectly segmented, noise-free lexicon, while largely ignoring how the lexicon is used. This paper combines both tasks in a novel framework for bootstrapping lexical acquisition and grammar induction.

We develop two related themes, learning procedures and knowledge transfer. This paper introduces two methods for learning procedures and one for transferring previously-learned knowledge to a slightly different task. We demonstrate by experiment that transfer accelerates learning.
