On Coherence Maintenance in Human-Machine Dialogue with Contextual Ellipses
نویسندگان
چکیده
The paper discusses a method for resolving referential ambiguity related with contextual ellipsis in human-machine dialogue. Necessary conditions for reconstructing elliptical phrases of a special kind—short answers or clarifications— are formulated. The first (most reliable) condition characterizes the lexical combinability; it is tested using a dictionary of collocations. The second one uses general information such as parts of speech, thus characterizing the most general syntactic combinability. The third one is based on the acceptability of the sentence with restored ellipsis. A heuristic algorithm for the restoration of the elliptical links using these three conditions is presented. The experimental results are discussed.
