Parsing beyond context-free grammars by Laura Kallmeyer

By Laura Kallmeyer

Given that context-free grammars (CFG) can't correctly describe common languages, grammar formalisms past CFG which are nonetheless computationally tractable are of vital curiosity for computational linguists. This publication offers an in depth evaluation of the formal language panorama among CFG and PTIME, relocating from Tree adjacent Grammars to a number of Context-Free Grammars after which to variety Concatenation Grammars whereas explaining to be had parsing options for those formalisms. even if familiarity with the elemental notions of parsing and formal languages is beneficial whilst examining this booklet, it's not a strict requirement. The presentation is supported with many illustrations and examples with regards to the several formalisms and algorithms, and bankruptcy summaries, difficulties and recommendations. The ebook can be worthy for college kids and researchers in computational linguistics and in formal language theory.

Literary Detective Work on the Computer by Michael P. Oakes

By Michael P. Oakes

Computational linguistics can be utilized to discover mysteries in textual content which aren't regularly visible to visible inspection. for instance, the pc research of writing variety can convey who should be the real writer of a textual content in circumstances of disputed authorship or suspected plagiarism. The theoretical historical past to authorship attribution is gifted in a step-by-step demeanour, and complete reports of the sphere are given in expert components, the writings of William Shakespeare and his contemporaries, and many of the writing types noticeable in spiritual texts. the ultimate bankruptcy seems to be on the growth desktops have made within the decipherment of misplaced languages. This booklet is written for college kids and researchers of normal linguistics, computational and corpus linguistics, and computing device forensics. it is going to motivate destiny researchers to check those themes for themselves, and offers enough info of the tools and assets to get them began.

Empirical Methods for Exploiting Parallel Texts by I. Dan Melamed

By I. Dan Melamed

Parallel texts (bitexts) are a goldmine of linguistic wisdom, as the translation of a textual content into one other language might be seen as a close annotation of what that textual content capability. wisdom approximately translational equivalence, which are gleaned from bitexts, is of vital significance for purposes resembling handbook and desktop translation, cross-language info retrieval, and corpus linguistics. the supply of bitexts has elevated dramatically because the introduction of the net, making their examine an exhilarating new region of study in common language processing. This booklet lays out the idea and the sensible options for locating and utilizing translational equivalence on the lexical point. it's a start-to-finish advisor to designing and comparing many translingual applications.

Semantic Role Labeling (Synthesis Lectures on Human Language by Martha Palmer, Daniel Gildea, Nianwen Xue

By Martha Palmer, Daniel Gildea, Nianwen Xue

This booklet is aimed toward supplying an outline of numerous facets of semantic function labeling. bankruptcy 1 starts off with linguistic historical past at the definition of semantic roles and the controversies surrounding them. bankruptcy 2 describes how the theories have ended in established lexicons similar to FrameNet, VerbNet and the PropBank body documents that during flip give you the foundation for giant scale semantic annotation of corpora. this knowledge has facilitated the advance of computerized semantic function labeling platforms in keeping with supervised computer studying innovations. bankruptcy three provides the final rules of making use of either supervised and unsupervised laptop studying to this activity, with an outline of the normal levels and have offerings, in addition to giving information of a number of particular structures. contemporary advances comprise using joint inference to exploit context sensitivities, and makes an attempt to enhance functionality through nearer integration of the syntactic parsing job with semantic position labeling. bankruptcy three additionally discusses the effect the granularity of the semantic roles has on process functionality. Having defined the fundamental procedure with appreciate to English, bankruptcy four is going directly to speak about utilizing an analogous innovations to different languages, utilizing chinese language because the basic instance. even if large education information is obtainable for chinese language, this isn't the case for plenty of different languages, and methods for projecting English position labels onto parallel corpora also are offered. desk of Contents: Preface / Semantic Roles / to be had Lexical assets / laptop studying for Semantic position Labeling / A Cross-Lingual point of view / precis

Cross-language Information Retrieval (Synthesis Lectures on by Jian-Yun Nie, Graeme Hirst

By Jian-Yun Nie, Graeme Hirst

Look for info is not any longer solely constrained in the local language of the consumer, yet is increasingly more prolonged to different languages. this provides upward push to the matter of cross-language details retrieval (CLIR), whose target is to discover proper info written in a special language to a question. as well as the issues of monolingual info retrieval (IR), translation is the main challenge in CLIR: one may still translate both the question or the records from a language to a different. notwithstanding, this translation challenge isn't similar to full-text computer translation (MT): the objective isn't really to provide a human-readable translation, yet a translation appropriate for locating suitable records. particular translation tools are therefore required. The target of this booklet is to supply a accomplished description of the specifi c difficulties bobbing up in CLIR, the ideas proposed during this quarter, in addition to the remainder difficulties. The ebook begins with a normal description of the monolingual IR and CLIR difficulties. assorted sessions of techniques to translation are then provided: techniques utilizing an MT method, dictionary-based translation and ways in response to parallel and similar corpora. moreover, the common retrieval effectiveness utilizing diverse techniques is in comparison. will probably be proven that translation methods in particular designed for CLIR can rival and outperform top quality MT platforms. ultimately, the ebook deals a glance into the longer term that pulls a powerful parallel among question enlargement in monolingual IR and question translation in CLIR, suggesting that many ways constructed in monolingual IR will be tailored to CLIR. The e-book can be utilized as an advent to CLIR. complicated readers may also locate extra technical info and discussions in regards to the closing learn demanding situations sooner or later. it's appropriate to new researchers who intend to hold out examine on CLIR.

Knowledge Engineering: Building Cognitive Assistants for by Gheorghe Tecuci, Dorin Marcu, Mihai Boicu, David A. Schum

By Gheorghe Tecuci, Dorin Marcu, Mihai Boicu, David A. Schum

This ebook provides an important development within the concept and perform of information engineering, the self-discipline eager about the improvement of clever brokers that use wisdom and reasoning to accomplish challenge fixing and decision-making projects. It covers the most levels within the improvement of a knowledge-based agent: realizing the appliance area, modeling challenge fixing in that area, constructing the ontology, studying the reasoning ideas, and checking out the agent. The publication makes a speciality of a distinct classification of brokers: cognitive assistants for evidence-based reasoning that study advanced problem-solving services at once from human specialists, aid specialists, and nonexperts in challenge fixing and selection making, and train their problem-solving services to scholars. a strong studying agent shell, Disciple-EBR, is integrated with the publication, permitting scholars, practitioners, and researchers to boost cognitive assistants quickly in a large choice of domain names that require evidence-based reasoning, together with intelligence research, cybersecurity, legislation, forensics, drugs, and schooling.
