Abstract

This paper describes a question answering system which is a limited instance of the general bidirectional architecture suggested by Appelt (1987), The novel features of our approach include the use of a linguistically well-motivated set of functional features; a bidirectional grammar which encodes these features directly; a question answering program which uses the thematic organisation of the user’s input to construct a cooperative reply; and a tactical generation component which can be used with Montague semantics.
