5 Conclusion
</SectionTitle>
    <Paragraph position="0"> We have outlined a framework for lexical semantic research that we believe earl be uselifl for both cornpvtational linguists and theoretical linguists alike.</Paragraph>
    <Paragraph position="1"> We argued against the view that word meanings are fixed and inflexible, where lexical ambiguity must be treated by multiple word entries in the lexicon.</Paragraph>
    <Paragraph position="2"> Rather, the lexicon can be seen ~ a generative system, where word senses are related by logical operations defined by the well-formedness rules of the semantics. In this view, much of the lexical ambiguity of highly ambiguous lexical items is eliminated because the semantic load is spread more evenly throughout the lexicon to the other lexical categories; furthermore, the lexical knowledge we propose as neeessary for ambiguity resolution is seen ms factored out at different levels of lexical representation. We looked at two of these levels, qualia structnre and lexieal inheritance, as they turn out to be of particular relevance to the structuring of the semantic information carried by e.g. nouns and adjectives, and applying it, via composition, to the construction of semantic interpretation of complex expressions. The methods underlying the analysis of ambignous phrases and the construction of corresponding semantic expressions make extended use of Kt{. devices and techniques.</Paragraph>
