1.2 WORD SENSE AMBIGUITY
</SectionTitle>
    <Paragraph position="0"> We will now discuss the issues connected with matching two different words based on their sernantie distance. Employing the notion of semantic similarity, it is necessary to address a number of problems. At first, we have to specify the semantic hierarchy. Second, we need to determine how to calculate the distance between two different concepts in the hierarchy. Finally we must determine how to select a sense of a word based on a context in which it appears.</Paragraph>
