There are several possible approaches to creating category systems for representing information about the world. One approach, which Smith calls the term orientation (see Chapter 4), is based on the observation that researchers often communicate their findings in the form of sentences[BS8]. What better way to create a category system than to base it on the meanings of the words in those sentences? One problem with this approach is that the meaning of a word often does not remain constant; it may change from context to context, as well as over the course of time[BS9]
