Modeling information structure in a cross-linguistic perspective

This study makes substantial contributions to both the theoretical and computational treatment of information structure, with a specific focus on creating natural language processing applications such as multilingual machine translation systems. The present study first provides cross-linguistic findings in regards to information structure meanings and markings. Building upon such findings, the current model represents information structure within the HPSG/MRS framework using Individual Constraints. The primary goal of the present study is to create a multilingual grammar model of information structure for the LinGO Grammar Matrix system. The present study explores the construction of a grammar library for creating customized grammar incorporating information structure and illustrates how the information structure-based model improves performance of transfer-based machine translation

Between syntax and morphology

Synopsis: This volume collects novel contributions to comparative generative linguistics that “rethink” existing approaches to an extensive range of phenomena, domains, and architectural questions in linguistic theory. At the heart of the contributions is the tension between descriptive and explanatory adequacy which has long animated generative linguistics and which continues to grow thanks to the increasing amount and diversity of data available to us. The chapters address research questions in comparative morphosyntax, including the modelling of syntactic categories, relative clauses, and demonstrative systems. Many of these contributions show the influence of research by Ian Roberts and collaborators and give the reader a sense of the lively nature of current discussion of topics in morphosyntax and morphosyntactic variation. This book is complemented by volume I available at https://langsci-press.org/catalog/book/275 and volume III available at https://langsci-press.org/catalog/book/277

Context and Composition: How Presuppositions Restrict the Interpretation of Free Variables

This dissertation develops a semantic analysis for frame-setting constructions, which operate at the interface between context and composition: Frame setters introduce a presupposition regarding the evaluation situation and thereby may restrict the interpretation of free variables.Die vorliegende Dissertation untersucht die Semantik von Rahmensetzungskonstruktionen. Der theoretische Kernbeitrag der Arbeit besteht in der formalsemantischen Analyse dieser Rahmensetzungskonstruktionen: Sie führen eine Präsupposition über mögliche Auswertungssituationen ein, welche freie Variablen indirekt, aber dennoch auf systematische und kompositionale Weise in ihren Wertzuweisungen beschränkt. Der empirische Haupteitrag der Dissertation besteht in der sprachvergleichenden Betrachtung dieser Konstruktionen

Incorporating Punctuation Into the Sentence Grammar: A Lexicalized Tree Adjoining Grammar Perspective

Punctuation helps us to structure, and thus to understand, texts. Many uses of punctuation straddle the line between syntax and discourse, because they serve to combine multiple propositions within a single orthographic sentence. They allow us to insert discourse-level relations at the level of a single sentence. Just as people make use of information from punctuation in processing what they read, computers can use information from punctuation in processing texts automatically. Most current natural language processing systems fail to take punctuation into account at all, losing a valuable source of information about the text. Those which do mostly do so in a superficial way, again failing to fully exploit the information conveyed by punctuation. To be able to make use of such information in a computational system, we must first characterize its uses and find a suitable representation for encoding them. The work here focuses on extending a syntactic grammar to handle phenomena occurring within a single sentence which have punctuation as an integral component. Punctuation marks are treated as full-fledged lexical items in a Lexicalized Tree Adjoining Grammar, which is an extremely well-suited formalism for encoding punctuation in the sentence grammar. Each mark anchors its own elementary trees and imposes constraints on the surrounding lexical items. I have analyzed data representing a wide variety of constructions, and added treatments of them to the large English grammar which is part of the XTAG system. The advantages of using LTAG are that its elementary units are structured trees of a suitable size for stating the constraints we are interested in, and the derivation histories it produces contain information the discourse grammar will need about which elementary units have used and how they have been combined. I also consider in detail a few particularly interesting constructions where the sentence and discourse grammars meet-appositives, reported speech and uses of parentheses. My results confirm that punctuation can be used in analyzing sentences to increase the coverage of the grammar, reduce the ambiguity of certain word sequences and facilitate discourse-level processing of the texts

Control, conflict, and motivation in socio-cultural context.

The central argument of this thesis is that unlike in the West, organizational behavior in the Middle East and the Indian sub-continent is, predominantly, not a function of work/task related imperatives but largely determined by the broader socio-cultural context, norms and values of the respective societies. Based on extensive interviews and participant and nonparticipant observation in the Middle East and sub-continent, and content analysis of media reports and lìterature, the effects of the respective socio-cultural contexts are documented in terms of three key determinants of organizational behavior, conflict, control and motivation. The thesis examines traditional and modern 'Western' sources of literature regarding control, conflict and motivation and the nature of culture itself and draws attention to the need for modification in certain 'Euroamerican' theories when applied to the strong social, familial and cultural structures, values, beliefs and assumptions present in the two other cultures investigated. Recommendations are put forward as to the kind of changes in the socio-cultural context of the Middle East and Indian sub-continent, if organizational behavior is to be transformed. In conclusion, a picture emerges of the stark differences between the cultures in terms of status, incomes, role of family and state, social control, family structure, population pressures and religious control - all of which are evidence of the predominance of the sociocultural context in determining organizational behavior. A theory is offered stating that organizational behavior is primarily a derivative of the structures and functions of broader socio-cultural institutions. A corollary of the said theory is that patterns of control, conflict, and motivation are strongly influenced by the structural-functional properties of a socio-cultural system, and hence, 'intrinsic motivation' is a rare phenomenon

On the boundaries between syntax and pragmatics in Ibero-Romance

Synopsis: This book offers a comparative perspective on the structural and interpretive properties of root-clause complementizers in Ibero-Romance. The driving question the author seeks to answer is where the boundaries between syntax and pragmatics lie in these languages. Contrary to most previous work on these phenomena, the author argues in favor of a relatively strict distribution of labor between the two components of grammar. The first part of the book is devoted to root complementizers with a reportative interpretation. The second part deals with root complementizers and commitment attribution. Finally, the last part presents the results of empirical studies on the topic

Chinese bank's credit risk assessment

This thesis studies the Chinese banks’ credit risk assessment using the Post Keynesian approach. We argue that bank loans are the major financial sources in emerging economies and it is uncertainty, an unquantifiable risk, rather than asymmetric information about quantifiable risk, as held by the mainstream approach, which is most important for the risk attached to credit loans, and this uncertainty is particularly important in China. With the universal existence of uncertainty, borrowers and lenders have to make decisions based on convention and experience. With regard to the nature of decision-making, this implies the importance of qualitative methods rather than quantitative methods. The current striking problem in Chinese banking is the large amount of Non-Performing Loans (NPLs) and this research aims to address the NPLs through improving credit risk management. Rather than the previous literature where Western models are introduced into China directly or with minor modification, this work advocates building on China’s conventional domestic methods to deal with uncertainty. We briefly review the background of the Chinese banking history with an evolutionary view and examine Chinese conventions in the development of the credit market. Based on an overview of this history, it is argued that Soft Budget Constraints (SBC) and the underdeveloped risk-assessing mechanism contributed to the accumulation of NPLs. Informed by Western models and experience, we have made several suggestions about rebuilding the Chinese convention of credit risk assessment, based on an analysis of publications and interviews with Chinese bankers. We also suggest some further development of the Asset Management Companies (AMCs) which are used to dispose of the NPLs
