Abstract

Building on the use of local contexts, or frames, for human category acquisition, we explore the treatment of contexts as categories. This allows us to examine and evaluate the categorical properties that local unsupervised methods can distinguish and their relationship to corpus POS tags. From there, we use lexical information to combine contexts in a way which preserves the intended category, providing a platform for grammatical category induction.
