Designed as a wide-ranging guide to Domain Specific Languages (DSLs) and how to approach building them, this book covers a variety of different techniques available for DSLs. The goal is to provide readers with enough information to make an informed choice about whether or not to use a DSL and what kinds of DSL techniques to employ. Part I is a 150-page narrative overview that gives you a broad understanding of general principles. The reference material in Parts II through VI provides the details and examples you´ll need to get started using the various techniques discussed. Both internal and external DSL topics are covered, in addition to alternative computational models and code generation. Although the general principles and patterns presented can be used with whatever programming language you happen to be using, most of the examples are in Java or C#. Product Description When carefully selected and used, Domain-Specific Languages (DSLs) may simplify complex code, promote effective communication with customers, improve productivity, and unclog development bottlenecks. In Domain-Specific Languages , noted software development expert Martin Fowler first provides the information software professionals need to decide if and when to utilize DSLs. Then, where DSLs prove suitable, Fowler presents effective techniques for building them, and guides software engineers in choosing the right approaches for their applications. This book´s techniques may be utilized with most modern object-oriented languages; the author provides numerous examples in Java and C#, as well as selected examples in Ruby. Wherever possible, chapters are organized to be self-standing, and most reference topics are presented in a familiar patterns format. Armed with this wide-ranging book, developers will have the knowledge they need to make important decisions about DSLs-and, where appropriate, gain the significant technical and business benefits they offer. The topics covered include: . How DSLs compare to frameworks and libraries, and when those alternatives are sufficient . Using parsers and parser generators, and parsing external DSLs . Understanding, comparing, and choosing DSL language constructs . Determining whether to use code generation, and comparing code generation strategies .

DSLs in Boo: Domain-Specific Languages in .NET
€ 39.99 *
ggf. zzgl. Versand

HIGHLIGHT A Domain Specific Language lets you express the intent of a piece of code in more human-readable terms. Boo is an ideal language to create DSLs for .NET. DESCRIPTION Even good code can be tough to understand when you simply read it-even if you´re a developer and you know what it does! A Domain Specific Language (DSL) helps a developer clearly express the intent of the code, and thus make it easier to work on the core business problem. Developers who migrate to Ruby from Java love Boo´s ability to define a DSL for .NET in a just few lines of code. In Boo, the developer can define simple DSLs for .NET applications without suffering through the awkward XML usually required. Building Domain Specific Languages in Boo shows how to write DSLs for .NET. It starts by teaching what a DSL is. Then, it provides a fast-paced Boo tutorial. Readers immediately start putting this handy language to productive use as they learn how to implement DSLs in real code. The author shows how to create several types of DSLs, all with the goal of making the developer more productive. Along the way, readers learn the Boo they need techniques to scare away the evil XML. KEY POINTS . Author Ayende Rahien is world-famous as a speaker and blogger on this topic . This book covers both the theory and the practice of building DSLs . This is the only book available that teaches Boo MARKET INFORMATION Anything that makes coding faster and better is of interest to developers. Writing DSLs has the potential to improve both speed of development and quality of code! This approach is unique, in that it brings a common technique for Ruby and Java developers to the .NET platform.

Domain-Specific Knowledge Graph Construction
€ 46.99 *
ggf. zzgl. Versand

The vast amounts of ontologically unstructured information on the Web, including HTML, XML and JSON documents, natural language documents, tweets, blogs, markups, and even structured documents like CSV tables, all contain useful knowledge that can present a tremendous advantage to the Artificial Intelligence community if extracted robustly, efficiently and semi-automatically as knowledge graphs . Domain-specific Knowledge Graph Construction (KGC) is an active research area that has recently witnessed impressive advances due to machine learning techniques like deep neural networks and word embeddings. This book will synthesize Knowledge Graph Construction over Web Data in an engaging and accessible manner. The book will describe a timely topic for both early -and mid-career researchers. Every year, more papers continue to be published on knowledge graph construction, especially for difficult Web domains. This work would serve as a useful reference, as well as an accessible but rigorous overview of this body of work. The book will present interdisciplinary connections when possible to engage researchers looking for new ideas or synergies. This will allow the book to be marketed in multiple venues and conferences. The book will also appeal to practitioners in industry and data scientists since it will have chapters on both data collection, as well as a chapter on querying and off-the-shelf implementations. The author has, and continues to, present on this topic at large and important conferences. He plans to make the powerpoint he presents available as a supplement to the work. This will draw a natural audience for the book. Some of the reviewers are unsure about his position in the community but that seems to be more a function of his age rather than his relative expertise. I agree with some of the reviewers that the title is a little complicated. I would recommend ´´Domain Specific Knowledge Graphs´´.

Integrating Natural Language Processing Compone...
€ 79.00 *
ggf. zzgl. Versand

This book describes novel software architectures for the integration of deep and shallow natural language processing (NLP) components in language technology. The generic markup language XML and the XML transformation language XSLT are used for flexible combination of linguistic markup produced by multiple NLP components. Shallow NLP components such as tokenizers, part-of-speech taggers, named entity recognizers and shallow parsers are combined with a deep parser, operating grammars written in the spirit of the Head-Driven Phrase Structure Grammar (HPSG) theory. The integration paradigm enables synergy leading to more robust deep parsing with increased coverage. It also constitutes a division of labor: the deep grammar models general, correct language use, while shallow systems are responsible for domain-specific extensions. Applications are presented in question answering, information extraction, natural language understanding, ontologies and the Semantic Web. The book addresses to software engineers, computational linguists and language technology engineers.
