In recent years, the coefficient of agreement has become the de facto standard to evaluate intercoder agreement for tagging tasks. In this squib, we highlight issues that affect and that the community has largely neglected. First, we discuss the assumptions underlying different computations of the expected agreement component of . Second, we discuss how(More)
Centering theory is the best-known framework for theorizing about local coherence and salience; however, its claims are articulated in terms of notions which are only partially specified, such as “utterance,” “realization,” or “ranking.” A great deal of research has attempted to arrive at more detailed specifications of these parameters of the theory; as a(More)
In this paper we will present our ongoing work on a plan-based discourse processor developed in the context of the Enthusiast Spanish to English translation system as part of the JANUS multi-lingual speech-tospeech translation system. We will demonstrate that theories of discourse which postulate a strict tree structure of discourse on either the(More)
Based on an ongoing attempt to integrate Natural Language instructions with human figure animation, we demonstrate that agents' understanding and use of instructions can complement what they can derive from the environment in which they act. We focus on two attitudes that contribute to agents' behavior their intentions and their expectations and shown how(More)
This chapter explores the correlation between centering and different forms of pronominal reference in Italian, in particular zeros and overt pronouns in subject position. In previous work (Di Eugenio, 1990), I proposed that such alternation could be explained in terms of centering transitions. In this chapter, I verify those hypotheses by means of a small(More)
In this paper, we investigate the empirical correlates of the agreement process. Informally , the agreement process is the dialogue process by which collaborators achieve joint commitment on a joint action. We propose a speciic instantiation of the agreement process , derived from our theoretical model, that integrates the IRMA framework for rational(More)
We describe a corpus-based investigation of proposals in dialogue. First, we describe our DRI compliant coding scheme and report our inter-coder reliability results. Next, we test several hypotheses about what constitutes a well-formed proposal. 1 I n t r o d u c t i o n Our project's long-range goal (see http://www.isp. p i t t .edu/in tgen/) is to create(More)
This paper presents our experiments in applying Latent Semantic Analysis (LSA) to dialogue act classification. We employ both LSA proper and LSA augmented in two ways. We report results on DIAG, our own corpus of tutoring dialogues, and on the CallHome Spanish corpus. Our work has the theoretical goal of assessing whether LSA, an approach based only on raw(More)
We discuss Feature Latent Semantic Analysis (FLSA), an extension to Latent Semantic Analysis (LSA). LSA is a statistical method that is ordinarily trained on words only; FLSA adds to LSA the richness of the many other linguistic features that a corpus may be labeled with. We applied FLSA to dialogue act classification with excellent results. We report(More)
