Intelligent Sensor Networks

In the last decade, wireless or wired sensor networks have attracted much attention. However, most designs target general sensor network issues including protocol stack (routing, MAC, etc.) and security issues. This book focuses on the close integration of sensing, networking, and smart signal processing via machine learning. Based on their world-class research, the authors present the fundamentals of intelligent sensor networks. They cover sensing and sampling, distributed signal processing, and intelligent signal learning. In addition, they present cutting-edge research results from leading experts

Proceedings of the 11th Workshop on Nonmonotonic Reasoning

These are the proceedings of the 11th Nonmonotonic Reasoning Workshop. The aim of this series is to bring together active researchers in the broad area of nonmonotonic reasoning, including belief revision, reasoning about actions, planning, logic programming, argumentation, causality, probabilistic and possibilistic approaches to KR, and other related topics. As part of the program of the 11th workshop, we have assessed the status of the field and discussed issues such as: Significant recent achievements in the theory and automation of NMR; Critical short and long term goals for NMR; Emerging new research directions in NMR; Practical applications of NMR; Significance of NMR to knowledge representation and AI in general

The significance of silence. Long gaps attenuate the preference for ‘yes’ responses in conversation.

In conversation, negative responses to invitations, requests, offers and the like more often occur with a delay – conversation analysts talk of them as dispreferred. Here we examine the contrastive cognitive load ‘yes’ and ‘no’ responses make, either when given relatively fast (300 ms) or delayed (1000 ms). Participants heard minidialogues, with turns extracted from a spoken corpus, while having their EEG recorded. We find that a fast ‘no’ evokes an N400-effect relative to a fast ‘yes’, however this contrast is not present for delayed responses. This shows that an immediate response is expected to be positive – but this expectation disappears as the response time lengthens because now in ordinary conversation the probability of a ‘no’ has increased. Additionally, however, 'No' responses elicit a late frontal positivity both when they are fast and when they are delayed. Thus, regardless of the latency of response, a ‘no’ response is associated with a late positivity, since a negative response is always dispreferred and may require an account. Together these results show that negative responses to social actions exact a higher cognitive load, but especially when least expected, as an immediate response

31th International Conference on Information Modelling and Knowledge Bases

Information modelling is becoming more and more important topic for researchers, designers, and users of information systems.The amount and complexity of information itself, the number of abstractionlevels of information, and the size of databases and knowledge bases arecontinuously growing. Conceptual modelling is one of the sub-areas ofinformation modelling. The aim of this conference is to bring together experts from different areas of computer science and other disciplines, who have a common interest in understanding and solving problems on information modelling and knowledge bases, as well as applying the results of research to practice. We also aim to recognize and study new areas on modelling and knowledge bases to which more attention should be paid. Therefore philosophy and logic, cognitive science, knowledge management, linguistics and management science are relevant areas, too. In the conference, there will be three categories of presentations, i.e. full papers, short papers and position papers

An Information theoretic approach to production and comprehension of discourse markers

Discourse relations are the building blocks of a coherent text. The most important linguistic elements for constructing these relations are discourse markers. The presence of a discourse marker between two discourse segments provides information on the inferences that need to be made for interpretation of the two segments as a whole (e.g., because marks a reason). This thesis presents a new framework for studying human communication at the level of discourse by adapting ideas from information theory. A discourse marker is viewed as a symbol with a measurable amount of relational information. This information is communicated by the writer of a text to guide the reader towards the right semantic decoding. To examine the information theoretic account of discourse markers, we conduct empirical corpus-based investigations, offline crowd-sourced studies and online laboratory experiments. The thesis contributes to computational linguistics by proposing a quantitative meaning representation for discourse markers and showing its advantages over the classic descriptive approaches. For the first time, we show that readers are very sensitive to the fine-grained information encoded in a discourse marker obtained from its natural usage and that writers use explicit marking for less expected relations in terms of linguistic and cognitive predictability. These findings open new directions for implementation of advanced natural language processing systems.Diskursrelationen sind die Bausteine eines kohärenten Texts. Die wichtigsten sprachlichen Elemente für die Konstruktion dieser Relationen sind Diskursmarker. Das Vorhandensein eines Diskursmarkers zwischen zwei Diskurssegmenten liefert Informationen über die Inferenzen, die für die Interpretation der beiden Segmente als Ganzes getroffen werden müssen (zB. weil markiert einen Grund). Diese Dissertation bietet ein neues Framework für die Untersuchung menschlicher Kommunikation auf der Ebene von Diskursrelationen durch Anpassung von denen aus der Informationstheorie. Ein Diskursmarker wird als ein Symbol mit einer messbaren Menge relationaler Information betrachtet. Diese Information wird vom Autoren eines Texts kommuniziert, um den Leser zur richtigen semantischen Decodierung zu führen. Um die informationstheoretische Beschreibung von Diskursmarkern zu untersuchen, führen wir empirische korpusbasierte Untersuchungen durch: offline Crowdsourcing-Studien und online Labor-Experimente. Die Dissertation trägt zur Computerlinguistik bei, indem sie eine quantitative Bedeutungs-Repräsentation zu Diskursmarkern vorschlägt und ihre Vorteile gegenüber den klassischen deskriptiven Ansätzen aufzeigt. Wir zeigen zum ersten Mal, dass Leser sensitiv für feinkörnige Informationen sind, die durch Diskursmarker kodiert werden, und dass Textproduzenten Relationen, die sowohl auf linguistischer Ebene als auch kognitiv weniger vorhersagbar sind, häufiger explizit markieren. Diese Erkenntnisse eröffnen neue Richtungen für die Implementierung fortschrittlicher Systeme der Verarbeitung natürlicher Sprache

Intentionality in translation : (with a special reference to Arabic/English translation)

This work springs from the subjective need for limiting the translation bias. It has been noticed that a considerable amount of translation is allowed to be published and read mainly due to the importance of its readability in the target language and often overlooking the goal(s) of the source text. This seems to derive from two common presumptions: (1) That a text goal is the result of an irretrievable and indescribable intentionality and (2) That target text readability and the preservation of the source text goal are two incompatible goals of translation. And this is in turn the result of the long lived dichotomy of translation studies into literal and free or text-based and reader oriented approaches. This work attempts to show that both (I) and (2) are misconceptions. Given a reasonable characterisation, intentionality is retrievable from the text itself and revealing of the text goal, the preservation of which does not exclude the readability of the TT and vice versa. Based on pragmatic insights drawn mainly from the Gricean Maxims and Cooperative Principle, Speech Act theory and the Text Linguistic model, this work proceeds to argue the case by analysing three Arabic texts and their twenty-two translations (each text is translated seven to eight times by different translators). These are of three most common types of prose: the expository, the argumentative and the instructive types. The analysis revolves around the identification of the text goal in the SL and its preservation in the TL. During this process a number of models and theories that constitute a controversial view of intentionality are outlined and discussed with a view to breaking the polarity they form and finding a medium path that is apt for charting more plausibly the context, the text and the process of translation. It is hoped that the implications of such work will help improve the quality of translation, provide a more explicit and plausible contribution to the account for the process and to further the effort towards standardising the theory

Elements of Structural Syntax

This volume is now finally available in English, sixty years after the death of its author, Lucien Tesnière. It has been translated from the French original into German, Spanish, Italian, and Russian, and now at long last into English as well. The volume contains a comprehensive approach to the syntax of natural languages, an approach that is foundational for an entire stream in the modern study of syntax and grammar. This stream is known today as dependency grammar (DG). Drawing examples from dozens of languages, many of which he was proficient in, Tesnière presents insightful analyses of numerous phenomena of syntax. Among the highlights are the concepts of valency and head-initial vs. head-final languages. These concepts are now taken for granted by most modern theories of syntax, even by phrase structure grammars, which represent, in a sense, the opposite sort of approach to syntax from what Tesnière was advocating
