A method for computing lexical semantic distance using linear functionals

This paper presents a novel, knowledge-based method for measuring semantic similarity in support of applications aimed at organizing and etrieving relevant textual information. We show how a quantitative context may be established for what is essentially qualitative in nature by ffecting a topological transformation of the lexicon into a metric space where distance is well-defined. We illustrate the technique with a simple xample and report on promising experimental results with a significant word similarity problem.
