TAILIEUCHUNG - Báo cáo khoa học: "Combining Linguistic and Gaze Features to Resolve Second-Person References in Dialogue"

We explore the problem of resolving the second person English pronoun you in multi-party dialogue, using a combination of linguistic and visual features. First, we distinguish generic and referential uses, then we classify the referential uses as either plural or singular, and finally, for the latter cases, we identify the addressee. In our first set of experiments, the linguistic and visual features are derived from manual transcriptions and annotations, but in the second set, they are generated through entirely automatic means. Results show that a multimodal system is often preferable to a unimodal one. . | Who is You Combining Linguistic and Gaze Features to Resolve Second-Person References in Dialogue Matthew Frampton 1 Raquel Fernandez1 Patrick Ehlen1 Mario Christoudias2 Trevor Darrell and Stanley Peters xCenter for the Study of Language and Information Stanford University frampton raquelfr ehlen peters @ 2International Computer Science Institute University of California at Berkeley cmch@ trevor@ Abstract We explore the problem of resolving the second person English pronoun you in multi-party dialogue using a combination of linguistic and visual features.

This is perhaps not surprising since the vast amount of work on anaphora and reference resolution has focused on text or discourse - mediums where second-person deixis is perhaps not as prominent as it is in dialogue. For spoken dialogue pronoun resolution modules however resolving you is an essential task that has an important impact on the capabilities of dialogue summarization systems. We thank the anonymous EACL reviewers and Surabhi Gupta John Niekrasz and David Demirdjian for their comments and technical assistance.
