Abstract
</SectionTitle>
    <Paragraph position="0"> This paper describes a novel system for acquiring adjectival subcategorization frames (SCFs) and associated frequency information from English corpus data.</Paragraph>
    <Paragraph position="1"> The system incorporates a decision-tree classifier for 30 SCF types which tests for the presence of grammatical relations (GRs) in the output of a robust statistical parser. It uses a powerful pattern-matching language to classify GRs into frames hierarchically in a way that mirrors inheritance-based lexica. The experiments show that the system is able to detect SCF types with 70% precision and 66% recall rate. A new tool for linguistic annotation of SCFs in corpus data is also introduced which can considerably alleviate the process of obtaining training and test data for subcategorization acquisition.</Paragraph>
