Focus Triggers and Focus Types from a Corpus Perspective

The article discusses several issues relevant for the annotation of written and spoken corpus data with information structure. We discuss ways to identify focus top-down (via questions under discussion) or bottom-up (starting from pitch accents). We introduce a two-dimensional labelling scheme for information status and propose a way to distinguish between contrastive and non-contrastive information. Moreover, we take side in a current debate, claiming that focus is triggered by two sources: newness and elicited alternatives (contrast). This may lead to a high number of semantic-pragmatic foci in a single sentence. In each prosodic phrase there can be one primary focus (marked by a nuclear pitch accent) and several secondary foci (marked by weaker prosodic prominence). Second occurrence focus is one instance of secondary focus

Acts of killing, acts of meaning:an application of corpus pattern analysis to language of animal-killing

We are currently witnessing unprecedented levels of ecological destruction and violence visited upon nonhumans. Study of the more-than-human world is now being enthusiastically taken up across a range of disciplines, in what has been called the ‘scholarly animal turn’. This thesis brings together concerns of Critical Animal Studies – along with related threads of posthumanism and new materialist thinking – and Corpus Linguistics, specifically Corpus Pattern Analysis (CPA), to produce a data-driven, lexicocentric study of the discourse of animal-killing. CPA, which has been employed predominantly in corpus lexicography, provides a robust and empirically well-founded basis for the analysis of verbs. Verbs are chosen as they act as the pivot of a clause; analysing them also uncovers their arguments – in this case, participants in material-discursive ‘killing’ events. This project analyses 15 ‘killing’ verbs using CPA as a basis, in what I term a corpus-lexicographical discourse analysis. The data is sampled from an animal-themed corpus of around 9 million words of contemporary British English, and the British National Corpus is used for reference. The findings are both methodological and substantive. CPA is found to be a reliable empirical starting point for discourse analysis, and the lexicographical practice of establishing linguistic ‘norms’ is critical to the identification of anomalous uses. The thesis presents evidence of anthropocentrism inherent in the English lexicon, and demonstrates several ways in which distance is created between participants of ‘killing’ constructions. The analysis also reveals specific ways that verbs can obfuscate, deontologise and deindividualise their arguments. The recommendations, for discourse analysts, include the adoption of CPA and a critical analysis of its resulting patterns in order to demonstrate the precise mechanisms by which verb use can either oppress or empower individuals. Social justice advocates are also alerted to potentially harmful language that might undermine their cause

Surface and Contextual Linguistic Cues in Dialog Act Classification: A Cognitive Science View

What role do linguistic cues on a surface and contextual level have in identifying the intention behind an utterance? Drawing on the wealth of studies and corpora from the computational task of dialog act classification, we studied this question from a cognitive science perspective. We first reviewed the role of linguistic cues in dialog act classification studies that evaluated model performance on three of the most commonly used English dialog act corpora. Findings show that frequency‐based, machine learning, and deep learning methods all yield similar performance. Classification accuracies, moreover, generally do not explain which specific cues yield high performance. Using a cognitive science approach, in two analyses, we systematically investigated the role of cues in the surface structure of the utterance and cues of the surrounding context individually and combined. By comparing the explained variance, rather than the prediction accuracy of these cues in a logistic regression model, we found that (1) while surface and contextual linguistic cues can complement each other, surface linguistic cues form the backbone in human dialog act identification, (2) with word frequency statistics being particularly important for the dialog act, and (3) the similar trends across corpora, despite differences in the type of dialog, corpus setup, and dialog act tagset. The importance of surface linguistic cues in dialog act classification sheds light on how both computers and humans take advantage of these cues in speech act recognition

Coordinating in dialogue: Using compound contributions to join a party

PhDCompound contributions (CCs) – dialogue contributions that continue or complete an earlier contribution – are an important and common device conversational participants use to extend their own and each other’s turns. The organisation of these cross-turn structures is one of the defining characteristics of natural dialogue, and cross-person CCs provide the paradigm case of coordination in dialogue. This thesis combines corpus analysis, experiments and theoretical modelling to explore how CCs are used, their effects on coordination and implications for dialogue models. The syntactic and pragmatic distribution of CCs is mapped using corpora of ordinary and task-oriented dialogues. This indicates that the principal factors conditioning the distribution of CCs are pragmatic and that same- and cross-person CCs tend to occur in different contexts. In order to test the impact of CCs on other conversational participants, two experiments are presented. These systematically manipulate, for the first time, the occurrence of CCs in live dialogue using text-based communication. The results suggest that syntax does not directly constrain the interpretation of CCs, and the primary effect of a cross-person CC on third parties is to suggest to them a strong form of coordination or coalition has formed between the people producing the two parts of the CC. A third experiment explores the conditions under which people will produce a completion for a truncated turn. Manipulations of the structural and contextual predictability of the truncated turn show that while syntax provides a resource for the construction of a CC it does not place significant constraints on where the split point may occur. It also shows that people are more likely to produce continuations when they share common ground. An analysis using the Dynamic Syntax framework is proposed, which extends previous work to account for these findings, and limitations and further research possibilities are outlined

Can structural priming answer the important questions about language? A commentary on Branigan and Pickering "An experimental approach to linguistic representation"

While structural priming makes a valuable contribution to psycholinguistics, it does not allow direct observation of representation, nor escape “source ambiguity.” Structural priming taps into implicit memory representations and processes that may differ from what is used online. We question whether implicit memory for language can and should be equated with linguistic representation or with language processing
