The paper investigates an elliptical construction, Clarification Ellipsis, that occurs in dialogue. We suggest that this provides data that demonstrates that updates resulting from utterances cannot be defined in purely semantic terms, contrary to the prevailing assumptions of existing approaches to dynamic semantics. We offer a computationally oriented analysis of the resolution of ellipsis in certain cases of dialogue clarification. We show that this goes beyond standard techniques used in anaphora and ellipsis resolution and requires operations on highly structured, linguistically (...) heterogeneous representations. We characterize these operations and the representations on which they operate. We offer an analysis couched in a version of Head-Driven Phrase Structure Grammar combined with a theory of information states (IS) in dialogue. We sketch an algorithm for the process of utterance integration in IS which leads to grounding or clarification. The account proposed here has direct applications to the theory of attitude reports, an issue which is explored briefly in the concluding remarks of the paper. (shrink)

Healey et al. use experiments with chat dialogues to test the hypothesis that language co‐ordination is driven by ‘running repairs’. They replace signals of understanding such as “okay” with weaker, ‘spoof’ signals like “ummm”, and replace specific requests for clarification like “on the left?” with signals that suggest a higher degree of misunderstanding like “what?”. The latter manipulation causes participants to switch rapidly to more abstract forms of referring expression.

Anecdotal evidence suggests that participants in conversation can sometimes act as a coalition. This implies a level of conversational organization in which groups of individuals form a coherent unit. This paper investigates the implications of this phenomenon for psycholinguistic and semantic models of shared context in dialog. We present a corpus study of multiparty dialog which shows that, in certain circumstances, people with different levels of overt involvement in a conversation, that is, one responding and one not, can nonetheless access (...) the same shared context. We argue that contemporary models of shared context need to be adapted to capture this situation. To address this, we propose “grounding by proxy,” in which one person can respond on behalf of another, as a simple mechanism by which shared context can accumulate for a coalition as a whole. We explore this hypothesis experimentally by investigating how people in a task-oriented coalition respond when their shared context appears to be weakened. The results provide evidence that, by default, coalition members act on each other's behalf, and when this fails they work to compensate. We conclude that this points to the need for a new concept of collective grounding acts and a corresponding concept of collective contexts in psycholinguistic and semantic models of dialog. (shrink)

Dialogue has its origins in joint activities, which it serves to coordinate. Joint activities, in turn, usually emerge in hierarchically nested projects and subprojects. We propose that participants use dialogue to coordinate two kinds of transitions in these joint projects: vertical transitions, or entering and exiting joint projects; and horizontal transitions, or continuing within joint projects. The participants help signal these transitions with project markers, words such as uh-huh, m-hm, yeah, okay, or all right. These words have been studied mainly (...) as signals of listener feedback (back-channel signals) or turn-taking devices (acknowledgment tokens). We present evidence from several types of well-defined tasks that they are also part of a system of contrasts specialized for navigating joint projects. Uh-huh, m-hm and yeah are used for horizontal transitions, and okay and all right for vertical transitions. (shrink)

Herbert Clark argues that language use is more than the sum of a speaker speaking and a listener listening. It is the joint action that emerges when speakers and listeners, writers and readers perform their individual actions in coordination, as ensembles. In contrast to work within the cognitive sciences, which has seen language use as an individual process, and to work within the social sciences, which has seen it as a social process, the author argues strongly that language use embodies (...) both individual and social processes.

This book presents one of the first attempts at developing a precise, grammatically rooted, theory of conversation motivated by data from real conversations. The theory has descriptive reach from the micro-conversational - e.g. self-repair at the word level - to macro-level phenomena such as multi-party conversation and the characterization of distinct conversational genres. It draws on extensive corpus studies of the British National Corpus, on evidence from language acquisition, and on computer simulations of language evolution. The theory provides accounts of (...) the opening, middle game, and closing stages of conversation. it also offers a new perspective on traditional semantic concerns such as quanitifcation and anaphora. The Interactive Stance challenges orthodox views of grammar by aruging that, unless we wish to excluse from analysis a large body of frequently occurrring words and constructions, the right way to construe grammar is as a system that characterizes types of talk in interaction.

The article is the first Russian translation of the most well-known piece in conversation analysis, written by the founders of CA Harvey Sacks, Emanuel Schegloff and Gail Jefferson. It has become a milestone in the development of the discipline. The authors offer a comprehensive approach to the study of conversational interactions. The approach is based on the analysis of detailed transcripts of the records of natural conversations. The authors show that in the course of the conversation co-conversationalists use a number (...) of techniques to organize the turn-taking. These techniques are combined in four rules: the first option is the transfer of speakership via allocation of the next speaker by the current speaker; if this first option is not realized, turn-taking may happen via the self-selection by one of the participants; if the second option remains unrealized too, the current speaker continues speaking, with all three options being recurrently provided at all next transition relevant places. The result of the operation of these rules is an orderly conversation based on the principle “one speaker at a time.” According to the authors, this model is compatible with obvious observations concerning conversational practices that they make. The authors show that in every conversation there is a turn-taking system in operation, which provides for a flexible adaptation of the every conversation’s structure to any possible topics and any possible speakers’ identities. Such approach considers how the participants in social interactions order their communication with each other, achieving a sense of normally occurring interaction. (shrink)

I will explore possibilities for formulating linguistic semantics in terms of records and record types of the kind used in recent developments of Martin-L¨of type theory (Betarte, 1998, Betarte and Tasistro, 1998, Coquand, Pollock and Takeyama, 2003, Tasistro, 1997). I will suggest that they give us the tools to develop a theory which includes aspects of Montague semantics, using the lambda calculus1, Discourse Representation Theory (DRT)2, situation semantics3 and Head-Driven Phrase Structure Grammar (HPSG)4 in a single theory. I will also (...) argue that formulating these theories in terms of record types may provide us not only with a unified approach but also with certain improvements over the individual theories.
