    <Paragraph position="0"> After examining the meanings, the prepositional uses of over have been divided into two groups: those whose meanings are identifiable by their Complements and those by their Heads. Previous studies have focused on the identification of the meanings of over, whereas the present paper not only on the meanings, but on the contexts for interpreting the meanings.</Paragraph>
    <Paragraph position="1"> Two decision trees have been proposed for determining the meanings of the prepositional uses of over by using the semantic features of the Head and Complement components. The decision trees are fairly simple and easy to implement in a system. The decision trees have been successful in identifying the meanings of the prepositional uses of over in data taken from BNC.</Paragraph>
