A Subcategory-based Parser Directed to Generating Representations for Text Understanding

This paper describes a parser in progress which is directed to generating representations for text understanding. For the purpose of reducing the proliferation of unwanted parse trees, and collecting information necessary for generating the semantic representations, the parser uses rules based on phrasal and lexical subcategories. These designs alleviate parsing problems such as PP attachment and coordination attachment, while capable of displaying the dependency of various types of phrases and clauses, thus facilitating the writing of grammar.
