Simons (2007) posits that parenthetical readings arise from the interaction between the report and the preceding discourse context, rather than from the syntax or semantics of the reports involved. However, no account of these discourse interactions has been developed in formal semantics. Research on parenthetical reports within frameworks of rhetorical structure has yielded hypotheses about the discourse interactions of parenthetical reports, but these hypotheses are not semantically sound. The goal of this paper is to unify and extend work in semantics and discourse structure to develop a formal, discourse-based account of parenthetical reports that does not suffer the pitfalls faced by current proposals in rhetorical frameworks.","PeriodicalId":37604,"journal":{"name":"Dialogue and Discourse","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83989305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While annotating opinions at the expression, the sentence or the document level is a well-established task and relatively straightforward, discourse annotation remains diffcult, especially for non experts. Therefore, combining both annotations poses several methodological problems that we address here. We propose a multi-layered annotation scheme that includes: the complete discourse structure according to the Segmented Discourse Representation Theory, the opinion orientation of elementary discourse units and opinion expressions, and their associated features. We detail each layer, explore the interactions between them and discuss our results. In particular, we examine the correlation between discourse and semantic category of opinion expressions, the impact of discourse relations on both subjectivity and polarity analysis and the impact of discourse on the determination of the overall opinion of a document. Our results demonstrate that discourse is an important cue for sentiment analysis, at least for the corpus genres we have studied.","PeriodicalId":37604,"journal":{"name":"Dialogue and Discourse","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80385907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obana, Michael Haugh","doi":"10.5087/DAD.2015.101","DOIUrl":"https://doi.org/10.5087/DAD.2015.101","url":null,"abstract":"The paper introduces a type of joint utterance construction in Japanese, in which two independent sentential-level units are amalgamated, which has hitherto received little attention in the literature. Unlike traditional joint utterance construction where one speaker maintains authority over the syntactic structure of the forthcoming continuation and the other accedes to this, thereby constituting a single TCU (turn constructional unit), our examples demonstrate that both speakers can have authority over the syntactic design of joint utterances. We call such collaborative utterances ‘co-authored joint utterances’ in this paper. \u0000The uniqueness of co-authored joint utterances lies in their syntactic architecture. While syntactic and semantic continuity are successfully achieved in constructing co-authored joint utterances, they represent a co-joined structure in which two sentential-level units are involved with their shared part constituting a point of amalgamation, and because of this, the structure of a co-authored joint utterance can no longer be parsed with extant grammar. \u0000In analysing co-authored joint utterances, we examine how they can be treated in relation to the distinction between TCU (Turn Constructional Unit) continuation and new TCUs. Due to the particularities of the syntactic architecture of co-authored joint utterances, their existence raises questions about the way in which this distinction is currently operationalised, because despite being syntactically an incremental continuation, and so seemingly a TCU continuation, the co-authored joint utterance implements an action beyond what was initially instantiated by the antecedent of that joint utterance, and so arguably constitutes a new TCU.","PeriodicalId":37604,"journal":{"name":"Dialogue and Discourse","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81321616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Miltsakaki","doi":"10.5087/dad.2014.101","DOIUrl":"https://doi.org/10.5087/dad.2014.101","url":null,"abstract":"Concession is one of the trickiest semantic discourse relations appearing in natural language. Many have tried to sub-categorize Concession and to define formal criteria to both distinguish its subtypes as well as for distinguishing Concession from the (similar) semantic relation of Contrast. But there is still a lack of consensus among the different proposals. In this paper, we focus on those approaches, e.g. Lagerwerf (1998), Winter and Rimon (1994), and Korbayova and Webber (2007), assuming that Concession features two primary interpretations, “direct” and “indirect”. We argue that this two way classification falls short of accounting for the full range of variants identified in naturally occurring data. Our investigation of one thousand Concession tokens in the Penn Discourse Treebank (PDTB) reveals that the interpretation of concessive relations varies according to the source of expectation. Four sources of expectation are identified. Each is characterized by a different relation holding between the eventuality that raises the expectation and the eventuality describing the expectation. We report a) a reliable inter-annotator agreement on the four types of sources identified in the PDTB data, b) a significant improvement on the annotation of previous disagreements on Concession-Contrast in the PDTB and c) a novel logical account of Concession using basic constructs from Hobbs (1998)’s logic. Our proposal offers a uniform framework for the interpretation of Concession while accounting for the different sources of expectation by modifying a single predicate in the proposed formulae.","PeriodicalId":37604,"journal":{"name":"Dialogue and Discourse","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77365011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such situations, verbal interactions are intertwined with \u0000actions, and shared goals can only be achieved via dynamic negotiation processes based on common ground constructed from discourse history as well as the interactants' knowledge about the status of actions. In this paper, we propose four major dimensions of collaborative tasks that affect the negotiation processes among interactants, and, hence, the structure of the dialogue. Based on a review of available dialogue corpora and annotation manuals, we show that existing annotation schemes so far do not adequately account \u0000for the complex dialogue processes in situated task-based scenarios.
