Conjunctions in natural language understanding Vicky Snarr Department of Computer Science University of Toronto Tuesday, 11 September, 3pm, Sandford Fleming Bldg 1105 Although the conjunction "and" appears to have a simple function in the English language, it has proved to be a stumbling block for both theoretical and computational linguists. One of the theoretical problems of conjunction is to determine what governs the acceptability of a structure in which two elements are connected by "and". The corresponding computational problem is, given this knowledge, to incorporate it into an efficient parser for English. I propose a solution to the theoretical problem which is in the form of two general constraints -- a syntactic constraint and a semantic one; and then show how these constraints were incorporated into a ``strictly deterministic'' parser for English. -- \\\\ Graeme Hirst University of Toronto Computer Science Department //// utcsrgv!utai!gh / gh.toronto@csnet-relay / 416-978-8747

ARTIFICIAL INTELLIGENCE SEMINAR
Tuesday, January 8, 1985
3:00 P.M. Sandford Fleming Building 1105

"Evaluating the Intelligence in Dialogue Systems"
The talk presents a set of criteria for evaluating intelligence in AI
computer systems which engage in dialogue with human users. It is divided
in five sections as follows:
(1) A definition of dialogue, characterization of a dialogue system, and
brief discussion of the concept of intelligence in dialogue systems.
(2) An elaboration of eight aspects of dialogue and dialogue systems.
(3) A discussion of four evaluative dimensions and an illustration of how
they may be combined with the aspects above to generate criteria for
designing and evaluating dialogue systems.
(4) Applications of some of these criteria to three example dialogue
systems: ELIZA, GUS, and GUIDON.
(5) A discussion of the current state of evaluation and our evaluative
methodology, and directions for future work.
