2 The TRIPS Parser and Logical Form
</SectionTitle>
    <Paragraph position="0"> The TRIPS grammar is a linguistically motivated uni cation formalism using attribute-value struc- null resentation is built in parallel with the syntactic representation. A sample logical form (LF) representation for Load the oranges into the truck is shown above. The TRIPS LF provides the necessary information for reference resolution, surface speech act analysis, and interpretations for a wide variety of fragmentary utterances and conventional phrases typical in dialog. The LF content comes from a domain-independent ontology adapted from FrameNet (Johnson and Fillmore, 2000; Dzikovska et al., 2004) and linked to a domain-independent lexicon (Dzikovska, 2004).</Paragraph>
    <Paragraph position="1"> The parser uses a bottom-up chart algorithm with beam search. Alternative parses are scored with factors assigned to grammar rules and lexical entries by hand, because due to the limited amount of corpus data we have not yet been able to train a statistical model that outperforms our hand-tuned factors.</Paragraph>
