Description : Master modern web and network data modeling: both theory and applications. In Web and Network Data Science, a top faculty member of Northwestern University’s prestigious analytics program presents the first fully-integrated treatment of both the business and academic elements of web and network modeling for predictive analytics. Some books in this field focus either entirely on business issues (e.g., Google Analytics and SEO); others are strictly academic (covering topics such as sociology, complexity theory, ecology, applied physics, and economics). This text gives today's managers and students what they really need: integrated coverage of concepts, principles, and theory in the context of real-world applications. Building on his pioneering Web Analytics course at Northwestern University, Thomas W. Miller covers usability testing, Web site performance, usage analysis, social media platforms, search engine optimization (SEO), and many other topics. He balances this practical coverage with accessible and up-to-date introductions to both social network analysis and network science, demonstrating how these disciplines can be used to solve real business problems.

Description : In this book, Cinque takes a generative perspective on typological questions relating to word order and to the syntax of relative clauses. In particular, Cinque looks at: the position of the Head vis à vis the relative clause in relation to the position of the verb vis à vis his object; a general cross-linguistic analysis of correlatives; the need to distinguish a sentence-grammar, from a discourse-grammar, type of non-restrictives (with languages differing as to whether they possess both, one, the other, or neither); a selective type of extraction from relative clauses; and a tentative sketch of a more ample work in progress on a unified analysis of externally headed, internally headed, and headless relative clauses.

Next, we will cover pattern recognition in text data utilizing classification mechanisms, perform entity recognition, and develop an ontology learning framework. By the end of the book, you will develop a practical application from the concepts learned, and will understand how text mining can be leveraged to analyze the massively available data on social media. Style and approach This book takes a hands-on, example-driven approach to the text mining process with lucid implementation in R.
Description : How many languages are there? Are new languages still being discovered? Why are so many languages disappearing? In this Very Short Introduction, eminent linguist Stephen Anderson addresses such questions as he illuminates the science behind languages. Considering a wide range of different languages and linguistic examples, Anderson provides the basic facts about the world's major families of spoken languages and their distribution around the globe. He explores the basis for linguistic classification and raises questions about how we identify a language. Considering signed languages as well as spoken, Anderson also examines the wider social issues of losing languages, and their impact on vanishing cultures and peoples.
Description : Although Portuguese is one of the main world languages and researchers have been working on Portuguese electronic text collections for decades (e.g. Kelly, 1970; Biderman, 1978; Bacelar do Nascimento et al., 1984; see Berber Sardinha, 2005), this is the first volume in English that encapsulates the exciting and cutting-edge corpus linguistic work being done with Portuguese language corpora on different continents. The book includes chapters by leading corpus linguists dealing with Portuguese corpora across the world, and their contributions explore various methods and how they are applicable to a wide range of language issues. The book is divided into six sections, each covering a key issue in Corpus Linguistics: lexis and grammar, lexicography, language teaching and terminology, translation, corpus building and sharing, and parsing and annotation. Together these sections present the reader with a broad picture of the field.
Description : This study explores the contemporary phenomenon of English as an international language, and sets out to analyze how and why the language has become so dominant.
