The pronoun /you/ is the second most frequent word in unrestricted spoken English dialogue. Despite this, its resolution has received very little attention in the literature. 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 conversation. 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.   

In this talk I shall present recent work on resolving second-person pronouns in multi-party dialogue using a machine learning approach. As it will be shown, the task is far from trivial. Firstly, there is the referentiality problem: while we generally conceive of the word /you/ as a deictic addressee-referring pronoun, it is often used in non-referential ways (including as a discourse marker and with a generic sense). Secondly, there is the reference problem: in utterances with referential cases, resolving a second person pronoun amounts to identifying the addressee(s) of the utterance in question. In conversations with multiple participants this is a complex problem where different kinds of linguistic and visual information play important roles.
