Semantic feedback is an important source of informa- tion that a parser could use to deal with local ambigu- ities in syntax. However, it is difficult to devise a sys- tematic communication mechanism for interactive syn- tax and semantics. In this article, I propose a variant of left-corner parsing to define the points at which syntax and semantics should interact, an account of grammat- ical relations and thematic roles to define the content of the communication, and a conflict resolution strategy based on independent preferences from syntax and se- mantics. The resulting interactive model has been im- plemented in a program called COMPERE and shown to account for a wide variety of psycholinguistic data on structural and lexical ambiguities.
