Download or read book Three Investigations of Extraction written by Paul Martin Postal and published by MIT Press. This book was released on 1998 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this technical monograph, Paul Postal deals with several issues that inexplicably have been treated only marginally in the development of current linguistic theorizing. He focuses on three problems in syntactic theory that are connected to "extraction" -- the occurrence of an element in a distinguished position distinct from its unmarked locus in simple clauses. He examines a largely ignored body of systematic contrasts among known extraction types, the status of the Coordinate Structure Constraint, and the phenomenon of Right Node Raising.

Download or read book Syntax Based Collocation Extraction written by Violeta Seretan and published by Springer Science & Business Media. This book was released on 2011-01-04 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Syntax-Based Collocation Extraction is the first book to offer a comprehensive, up-to-date review of the theoretical and applied work on word collocations. Backed by solid theoretical results, the computational experiments described based on data in four languages provide support for the book’s basic argument for using syntax-driven extraction as an alternative to the current cooccurrence-based extraction techniques to efficiently extract collocational data. The work described in Syntax-Based Collocation Extraction focuses on using linguistic tools for corpus-based identification of collocations. It takes advantage of recent advances in parsing to propose a novel deep syntactic analytic collocation extraction that has applicability to a range of important core tasks in Computational Linguistics. The book is useful for anyone interested in computational analysis of texts, collocation phenomena, and multi-word expressions in general.
Download or read book Investigations in Entity Relationship Extraction written by Sachin Sharad Pawar and published by Springer Nature. This book was released on 2022-10-17 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers several entity and relation extraction techniques starting from the traditional feature-based techniques to the recent techniques using deep neural models. Two important focus areas of the book are – i) joint extraction techniques where the tasks of entity and relation extraction are jointly solved, and ii) extraction of complex relations where relation types can be N-ary and cross-sentence. The first part of the book introduces the entity and relation extraction tasks and explains the motivation in detail. It covers all the background machine learning concepts necessary to understand the entity and relation extraction techniques explained later. The second part of the book provides a detailed survey of the traditional entity and relation extraction problems covering several techniques proposed in the last two decades. The third part of the book focuses on joint extraction techniques which attempt to address both the tasks of entity and relation extraction jointly. Several joint extraction techniques are surveyed and summarized in the book. It also covers two joint extraction techniques in detail which are based on the authors’ work. The fourth and the last part of the book focus on complex relation extraction, where the relation types may be N-ary (having more than two entity arguments) and cross-sentence (entity arguments may span multiple sentences). The book highlights several challenges and some recent techniques developed for the extraction of such complex relations including the authors’ technique. The book also covers a few domain-specific applications where the techniques for joint extraction as well as complex relation extraction are applied.
Download or read book Multi source Multilingual Information Extraction and Summarization written by Thierry Poibeau and published by Springer Science & Business Media. This book was released on 2012-08-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information extraction (IE) and text summarization (TS) are powerful technologies for finding relevant pieces of information in text and presenting them to the user in condensed form. The ongoing information explosion makes IE and TS critical for successful functioning within the information society. These technologies face particular challenges due to the inherent multi-source nature of the information explosion. The technologies must now handle not isolated texts or individual narratives, but rather large-scale repositories and streams---in general, in multiple languages---containing a multiplicity of perspectives, opinions, or commentaries on particular topics, entities or events. There is thus a need to adapt existing techniques and develop new ones to deal with these challenges. This volume contains a selection of papers that present a variety of methodologies for content identification and extraction, as well as for content fusion and regeneration. The chapters cover various aspects of the challenges, depending on the nature of the information sought---names vs. events,--- and the nature of the sources---news streams vs. image captions vs. scientific research papers, etc. This volume aims to offer a broad and representative sample of studies from this very active research field.

Download or read book Extraction Asymmetries written by Tanja Kiziak and published by John Benjamins Publishing. This book was released on 2010 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph addresses divergent views in the linguistic literature on whether German displays the "that"-trace effect and other subject/object asymmetries commonly found for long extractions in English and other languages. Using newly developed rating methodologies, the author exposes consistent and robust subject/object asymmetries in German a surprisingly unequivocal result given that the existence of these effects is controversial. This finding raises important questions: how can one account for the discrepancy between the clear experimental evidence on the one hand, and the lack of consensus in the linguistic literature on the other? And secondly, it raises again the old question of why subject extractions are dispreferred. This work also provides intriguing new insights into the long-standing question on how to analyse German constructions such as "Wer glaubst du hat recht"? the parenthesis versus extraction debate'. In this work decisive evidence points in favour of the parenthetical analysis."

Download or read book Knowledge Mining written by Spiros Sirmakessis and published by Springer Science & Business Media. This book was released on 2005-10-20 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Text mining is an exciting application ?eld and an area of scienti?c - search that is currently under rapid development. It uses techniques from well-established scienti?c ?elds (e. g. data mining, machine learning, infor- tion retrieval, natural language processing, case-based reasoning, statistics and knowledge management) in an e?ort to help people gain insight, und- stand and interpret large quantities of (usually) semi-structured and unstr- tured data. Despite the advances made during the last few years, many issues remain unresolved. Proper co-ordination activities, dissemination of current trends and standardisation of the procedures have been identi?ed, as key needs. There are many questions still unanswered, especially to the potential users; what is the scope of Text Mining, who uses it and for what purpose, what constitutes the leading trends in the ?eld of Text Mining – especially in relation to IT – and whether there still remain areas to be covered. Knowledge Mining draws upon many of the key concepts of knowledge management, data mining and knowledge discovery, meta-analysis and data visualization. Within the context of scienti?c research, knowledge mining is principally concerned with the quantitative synthesis and visualization of - search results and ?ndings. The results of knowledge mining are increased scienti?c understanding along with improvements in research quality and value. Knowledge mining products can be used to highlight research opportunities, assist with the p- sentation of “best” scienti?c evidence, facilitate research portfolio mana- ment, as well as, facilitate policy setting and decision making.

Download or read book On Extraction and Extraposition in German written by Uli Lutz and published by John Benjamins Publishing. This book was released on 1996-01-01 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extraction has traditionally been one of the main topics in generative grammar, and it retains this status in current variants of the theory. German provides a good testing ground for traditional as well as current theories of extraction. The nine contributions to this volume document the recent lively discussions on the adequate analyses of extraction constructions, on the impact of extraction on semantic interpretation, and, above all, on the question of which constructions are to be analysed as extractions and which not. Uli Lutz gives an overview of extraction theory. Marga Reis challenges the standard analysis of extraction from verb-second clauses and opts for a parenthetic analysis. Franz d’Avis confronts current approaches to wh-islands with the facts in German and investigates the semantic properties of topicalization from wh-clauses. Sigrid Beck derives various negative island effects from a constraint on Logical Form. Jürgen Pafel relates the differences between two kinds of extraction from noun phrases to the structure of the noun phrases. Daniel Büring and Katharina Hartmann argue for the traditional analysis of extraposition as rightward movement, based on a detailed comparison with alternative accounts. Gereon Müller derives the peculiar restrictions on extraposition from a theory of improper movement. Hubert Haider defends his analysis of extraposition as a base-generated construction against his critics. Chris Wilder develops a minimalist account of extraposition and takes extraposition and coordination ellipsis to be instances of the same process.

Download or read book Natural Language Processing for Online Applications written by Peter Jackson and published by John Benjamins Publishing. This book was released on 2007-06-05 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text covers the technologies of document retrieval, information extraction, and text categorization in a way which highlights commonalities in terms of both general principles and practical concerns. It assumes some mathematical background on the part of the reader, but the chapters typically begin with a non-mathematical account of the key issues. Current research topics are covered only to the extent that they are informing current applications; detailed coverage of longer term research and more theoretical treatments should be sought elsewhere. There are many pointers at the ends of the chapters that the reader can follow to explore the literature. However, the book does maintain a strong emphasis on evaluation in every chapter both in terms of methodology and the results of controlled experimentation.
