OK for implementors
If you want to implement a compression scheme fast easily, or to havegeneral knowledge about compression algorithms this is a very good book. Ifyou really want to deeply understand compression algorithms, to have somekind of insight about them, and to know about the best algorithms availabletoday - this book is has less benefit (understatement).

a book which has its positive and negative sides...
PROs: 1. It is one of very few books on data compression available on the market. 2. Description of the IDEAS of compression techniques is very well written. 3. The books comes with the C code for most algorithms. 4. Fairlywide scope of data compression techniques is presented.

CONs: 1. Possiblyfor copyright reasons, the formats of commonly used file formats are notdisclosed; the enclosed propgrams are generic compression algorithms, whichdo not create (or open) actual .ZIP, .ARC, or .JPG files, which can beopened by commercial programs. Therefore, this book will not help you toopen standard compressed files from your home-made programs. 2. There is amissing link between the well described ideas (general principles) of thecompression techniques, and their actual algorithms presented as C programs- namely, the algorithms are not described verbally. You have to analyzetypically 6-page-long programs to understand how the actual encoding isdone. 3. Although there is a section on sound compression, the MP3 standardis not explained. The same applies to MPEG.

SUMMARY: Good to get ageneral idea how the data compression is performed. Helpful if you want todevelop your own compressed data format. Of very limited help if you wantto work with standard compressed files in your own program. Requiresknowledge of C and some time to study the enclosed code.

Too much about C programming, not enough about compression
This book's target audience is the novice C programmer who needs to implement data compression of some kind.The authors go to great pains to explain exactly how the code works, but they don't do as good a job on thealgorithms themselves.If you are a competent C programmer and/or have anyformal training in algorithms, this is probably not the book for you,though it may be a good jumping-off point if it's the only book you can getyour hands on.

The best book for programmers needing algorithms not theory.
This book did a better job than any other of teaching me sliding window dictionary encoding and adaptive huffman encoding.It got right to the point in an easy to understand fashon.There was no thick cloud of theorymasking the information I needed.Read this book before you read others onthe subject of data compression. ...

Needs a to be updated
Used it as a text book, mainly a reference. With communications rapidly changing it must be difficult to continually update.It is a fair background book, but it doesn't offer much else

Book is too dated to be effective in emerging technologies.
Although updated in 1994, most of the text material discusses old mainframe and terminal applications and was likely written during earliereditions of the text.Reading it did not provide a good basis for the telecommunications area, because it is so dated.In its day, it must have been a great text. ...

The presentation of a coherent methodology for the estimation of the parameters of mathematical models from experimental data is examined in this volume. Many topics are covered including the choice of the structure of the mathematical model, the choice of a performance criterion to compare models, the optimization of this performance criterion, the evaluation of the uncertainty in the estimated parameters, the design of experiments so as to get the most relevant data and the critical analysis of results. There are also several features unique to the work such as an up-to-date presentation of the methodology for testing models for identifiability and distinguishability and a comprehensive treatment of parametric optimization which includes greater consider ation of numerical aspects and which examines recursive and non-recursive methods for linear and nonlinear models. ...

Product Description

Gaining access to high-quality data is a vital necessity in knowledge-based decision making. But data in its raw form often contains sensitive information about individuals. Providing solutions to this problem, the methods and tools of privacy-preserving data publishing enable the publication of useful information while protecting data privacy. Introduction to Privacy-Preserving Data Publishing: Concepts and Techniques presents state-of-the-art information sharing and data integration methods that take into account privacy and data mining requirements.

The first part of the book discusses the fundamentals of the field. In the second part, the authors present anonymization methods for preserving information utility for specific data mining tasks. The third part examines the privacy issues, privacy models, and anonymization methods for realistic and challenging data publishing scenarios. While the first three parts focus on anonymizing relational data, the last part studies the privacy threats, privacy models, and anonymization methods for complex data, including transaction, trajectory, social network, and textual data.

This book not only explores privacy and information utility issues but also efficiency and scalability challenges. In many chapters, the authors highlight efficient and scalable methods and provide an analytical discussion to compare the strengths and weaknesses of different solutions.

The Dictionary of PC Hardware and Data Communications Terms coversterms in two of the most volatile and interesting areas of computerdevelopment: personal computers and networks.To create this comprehensivedictionary, the author combed the Internet and other online services to findthe latest and most vexing acronyms and terms.It contains up-to-dateinformation about everything from a common item like "batteries" to anobscure font technology called "Speedo." In a way it's inaccurate to call this a dictionary because it providesdetailed, useful descriptions of complex terms.For example, thedescription of PGP (Pretty Good Privacy), a popular data encryptionprotocol, covers three and one-half pages.The entry for PowerPCcontains a table listing the clock speed, transistors, width in bits,cache in kilobytes, and pins of each PowerPC processor currently in use. Terms are carefully cross-referenced as well. ... Read more

Still Not Lifeless
This "Dictionary of PC Hardware and Data Communications Terms" is really agreat book for those that want to know more than just what an acronymstands for. All the entries are longer discussions of the technology, withloads of tables, dates, which companies support the technology, where thetechnology is standardized, what it competes with and what its shortcomingsare. And all entries have cross-references to related entries in the book,and most have World Wide Web references as well. I use this dictionary fortwo years. Today it is old but still not dead.

Great to learn all the data terms
I would have to say that this is the most used book in my office. We havethe data down pat, but the telco's have so many terms and acronyms that Iwould not be able to talk to a telco person if I was not able to look upthe TLA's after the conversation. I highly recommend this book to anyone -from beginner to the advanced. ... Read more

Product Description
Text-based interaction among humans connected via computer networks, such as takes place via e-mail on the Internet and in synchronous modes such as "chat", MUDs and MOOs, has attracted considerable popular and scholarly attention. This collection of 14 articles on text-based computer-mediated communication (CMC) brings empirical evidence from a variety of disciplinary perspectives to bear on questions raised by the new medium. The first section, linguistic perspectives, addresses the question of how CMC compares with speaking and writing, and describes its structural characteristics. Section Two, on social and ethical perspectives, explores conflicts between the interests of groups and those of individual users, including issues of on-line sex and sexism. In the third section, cross-cultural perspectives, the advantages and risks of using CMC to communicate across cultures are examined in three studies involving users in East Asia and Mexico, and students of ethnically diverse backgrounds in remedial writing classes in the United States.The final section deals with the effects of CMC on group interaction: in a women's studies mailing list, a hierarchically-organized workplace, and a public protest on the Internet against corporate interests. The book also includes a bibliography with nearly 200 references to published research on CMC. ... Read more
