The Computational Dictionary, described in this paper, is structured on a knowledge base. The semantic features of each word, in a relevant grammatical category, can be determined through a hierarchical tree structure. Semantic knowledge of verbs is represented using predicate calculus definitions. This allows each expression, e.g. sentence or command, to be tested in order to determine whether it is meaningful and, if meaningful, what its meaning is or indeed whether it is ambiguous.
