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;(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)
This paper presents a first-order logic learning approach to determine rhetorical relations between discourse segments. Beyond linguistic cues and lexical information, our approach exploits compositional semantics and segment discourse structure data. We report a statistically significant improvement in classifying relations over attribute-value learning(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 show how(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)
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 multilingual speech-to-speech translation system. We will demonstrate that theories of discourse which postulate a strict tree structure of discourse on either the(More)
This paper presents an analysis of purpose clauses in the context of instruction understanding. Such analysis shows that goals affect the interpretation and / or execution of actions, lends support to the proposal of using generation and enablement to model relations between actions, and sheds light on some inference processes necessary to interpret purpose(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)
