Abstract

In this article, we investigate the use of semantic information in parse selection. We show that fully disambiguated sense-based semantic features smoothed using ontological information are effective for parse selection. Training and testing was undertaken using definition and example sentences taken from a Japanese dictionary corpus (Hinoki), which is manually annotated with senses. A model employing both syntactic and semantic information provides better parse selection accuracy than a model using only syntactic features.
