Abstract:
Interpretation of natural language is inherently context-sensitive.
Most words in natural language are ambiguous and their meaning is heavily
dependent on
the linguistic context in which they are used. The study of lexical
semantics can not be separated from the notion of context. This paper takes
a contextual
approach to lexical semantics and studies the linguistic context of
lexical atoms, or "sticky" phrases such as "hot dog". Since such lexical
atoms may occur
frequently in unrestricted natural language text, recognizing them
is crucial for understanding naturally-occuring text. The paper proposes
several heuristics
approaches to exploiting the linguistic context to identify lexical
atoms from arbitrary natural language text.
