This paper introduces MDRT, an extension of DRT to a multi-agent dialogue. The main issue handled is cross-speaker anaphora, whereby one speaker refers anaphorically to a discourse entity introduced by another speaker. We present a representation of multispeaker discourses that allows a a non-degenerate solution to the commitment problem: to what conditions about a discourse entity is a speaker committed when using cross-speaker anaphora? 1.

Two notable examples are the (similar) theories presented in [5, 4]. Also related is the theory in [3], striving, in addition, towards compositionality. A focus of attention in all of these theories is the treatment of inter-sentential anaphora. In these theories, meaning is ta...
