Wrought with errors.......2006-02-28
While some of the puzzles give enough information to solve them and some of the answers are correct, a great number of answers are incorrect or the puzzle doesn't give enough information to arrive at an any answer, much less the one given.
Case in point. I paraphrase so as not to spoil it: Question says people "were planning" to hand items out at a party. The items are consumed, it explains. Then asks "how many" of the items "did they take" to the event. The answer should be 0 as they consumed them all, but the book's answer states how many they "would have brought" or how many they started with. One, the answer and question don't match. Two, given the lack of info on the starting number and the use of 'half' etc, there can be multiple answers for what they started with. The question was how many they took. This book needs major editing.
For a man who is brilliant, he or the publisher should have made sure the questions were thorough and the answers accurate. Frankly I'm dissapointed in the book and do not recommmend this book.
Fast and Fun Puzzling.......2005-04-04
I love this book! All those who enjoy puzzles will love the format of this book - which are short puzzles that require nothing but a little brainpower to figure out.
Many of the puzzles you can't figure out will have you slapping your forehead and shouting, "Of COURSE!" when the answer is revealed. That's the fun of puzzles like these, in my opinion. Add to this the wide variety of puzzles you'll find in this book - something for everyone for sure - and you'll consider this book among your puzzle book favorites. It makes a great gift too!
A must-have for puzzle lovers!!.......2004-11-16
I picked up the "Little Book of Bathroom Brainteasers" and was pleased to find this book is filled with a wide range of very innovative and highly challenging puzzles. I was impressed by the unique puzzle content--definitely not your same old brain-teasers! This book is really a lot of fun and I very strongly recommend it for anyone who enjoys brain-teasers and puzzle solving.

Customer Reviews:
Good content overall.......2005-05-13
I used this book in graduate school while taking the Database Management System course. The book has usefull information. It help me understand and practice normalization. Some unfamiliar concepts also were learnt from the book. I can recommend this book to anyone getting into the database world.
Very practical........2004-04-26
Indeed, a brilliant rendition of practical information. I am currently working as a chief technical designer in a financial data warehouse project for a fortune 100 company. Chapter 11 (Data Warehousing) unfolded some time-critical points.
IT'S POORLY ORGANIZED AND DIFFICULT TO FOLLOW; NOT INTRO BK.......2003-07-20
This is a required textbook for an Intro to DB course. Once again, the University of Texas at Dallas has followed a constant pattern of requiring textbooks that are 1) Poorly organized/written books, 2) expensive and 3)The professor haven't read the book themselves AND are not using/following a required book when teaching their course! This said, my review of this book.
IT'S POORLY ORGANIZED AND DIFFICULT TO FOLLOW; NOT AN INTRO DB BOOK!
For example: "Relational Database" - The book begin this topic on "PAGE 11", but does not define nor clearly explain what this is; the book glorify how "...preliminary studies convinced management of the potential advantage of this approach...modern company should implement..." Then, it talks about "Implementing the Relational Database." Ok, but what the f**k is a Relational database! This continues on until finally at "PAGE 259" when it FINALLY defines what this is.
Good luck!
Explains in Depth, important Info.......2003-07-17
Much like Hoffer's other book, which focuses on an earlier stage in the Sys. Devel. Life Cycle (Analysis & Design), this is the next book in "the series".
This book goes over some of the fundamental concepts of modeling and relationship diagramming which were covered in the previous book. However, it picks up where the other left off and explain in-depth Database creation maintainence, and so on to a point where most can understand, and all can benefit from. Another good job from these strong Authors
Very Useful.......2003-06-19
I bought this book for my database class and I found this book to be very useful. If this is your area of study, I would suggest keeping the book as a reference guide. I regret selling mine to a friend, as there were plenty of times where I thought I could refer back to it in other courses and projects.
Book Description
Written from a multidisciplinary user/manager approach—rather than a designer approach, this text looks at data warehousing technologies necessary to support the business processes of the twenty-first century. It explores the basic concepts of data mining, warehousing, and visualization—with an emphasis on both technical and managerial issues and the implication of these modern emerging technologies on those issues. Includes mini-cases, narrative vignettes, and an abundance of graphics. Data mining and visualization exercises—using an included fully-enabled, but time-limited version of Megaputer's PolyAnalyst and TextAnalyst data mining and visualization software—give readers hands-on experience with real-world applications. The Data Warehouse. Data Mining and Data Visualization. Data Mining Technologies. Executive Information Systems. Designing and Building the Data Warehouse. The Future of Data Mining, Warehousing, and Visualization.
Customer Reviews:
Good book.......2007-01-18
Is a very good introduction in Information Retrieval from a modern perspective.The book approaches the field in a rigorous and complete way from a computer-science perspective.
Ok for basics.......2006-03-23
This book covers most of the basics but is far from being up to date in technology. The student would be better off looking at the TREC website and reading papers submitted by participants.
Excellent as a textbook and a practical guide.......2006-03-17
I used this book as a textbook in a course on information storage and retrieval that I took a few years back, and it is still my favorite book on the subject. It explains the concepts clearly yet has all of the necessary mathematical and algorithmic details needed to work with the subject matter.
Chapter one just acts as a guide to the rest of the book. The book is basically divided into four parts: text IR, human-computer interfacing for IR, multimedia IR, and applications of IR. The part on text IR is best for beginners trying to learn the overall subject of IR, and consists of chapters 2 through 9. Chapter 2 is a long and important chapter that introduces fundamental concepts in IR and lays foundations for later chapters. Models for "ranking" documents based on queries are presented, including the boolean, vector, probabilistic, and fuzzy models. Chapter 3 is far less technical than chapter 2 and focuses on evaluation of IR models. Chapter 4 is an introduction to query languages, which are necessary for the elegant presentation of complex queries. Chapter 5 deals with query operations, which is the transformation of queries from simple keywords into weighted sets of terms and also includes user feedback. As in previous chapters, there is quite a bit of mathematics involved. Chapter 6 is devoted to text languages such as HTML and SGML since the user might refer to the structure of a document in his/her query, and that structure must be defined somewhere. Chapter 7 is about operations on documents themselves for the purpose of simplifying them for quick search. Thus, it is important as a time saver to eliminate common words such as "the" and also to reduce words to their grammatical roots. The potentially large size of document collections requires special indexing techniques for efficient retrieval. This is the subject of Chapter 8. Query processing can be further accelerated by using the parallel and distributed IR techniques discussed in Chapter 9, which concludes the book's discussion of text IR.
Chapter 10 is a stand-alone chapter on HCI for IR that discusses the design of user interfaces that assist the user in forming a query and current approaches for visualization of large data sets.
Multimedia IR is discussed in chapters 11 and 12. Models and query languages for office and medical information systems are discussed in Chapter 11. Efficient indexing and searching of multimedia objects is discussed in Chapter 12.
The final three chapters of the book are about the applications of IR. There is a chapter each about searching the web, bibliographic systems, and digital libraries.
The chapter on text languages is starting to show its age, as are the chapters on IR applications at the end of the book. The chapters on algorithms, and particularly the algorithmic portions of the chapters on text IR cause this book to remain a worthwhile read. There is quite a bit of mathematics used in this book, and probability theory in particular. Thus, the reader should already be familiar with probability theory and the basics of pattern recognition to get the most from this book.
Excellent research source.......2005-10-24
This is an excellent book for those interested in getting an overview of IR. The book summarizes all the important milestones of IR up to 1999 (There are 852 references in the bibliography!). The writing is concise yet eloquent. The authors try to cover as much ground as possible, providing a gold-mine of information comparing the pros and cons of the various types of implementation. However, I believe that due to the breadth of the techniques covered, some of the explanations for the algorithms were rather brief and not very illuminating. But no worries, there are ample references to point you back to the writings of the orignal authors so you can get right back on track.
Great textbook for computer science undergraduate and graduate courses and reference for IR practitioners.......2005-09-06
Modern Information Retrieval is a textbook for computer science undergraduate and graduate courses and a reference book for IR practitioners.
The book structure consists of a Preface, Acknowledgements, Biographies, fifteen chapters, Appendix, Glossary, References and Index. The first part of the book is authored or co-authored and addresses query and text operations, retrieval and indexing. The second part consists of special topics authored by leading researchers in their fields. This part focuses on architecture, multimedia IR, bibliographical systems and digital libraries.
The Glossary section of this book consists of 18 pages and defines important technical terms used in IR. The References section consists of 45 pages of significant IR work. The Index section consists of 13 pages, which enhances the book usability. Each chapter ends with a Trends and Research Issues and a Bibliographic Discussion section.
The best features of the book are its cohesive presentation and organization. The use of a common nomenclature and notation helps students and readers to assimilate key concepts and with "connecting the dots" across chapters. The text is reinforced by a mirrored Web site with several resources, errata page and teaching material. In Chapter 1, the authors even "go the extra mile" with teachers and suggest how chapters could be used with different undergraduate and graduate courses. All this makes the book a great educational resource for students and teachers.
This book is recommended for computer science courses at the undergraduate and graduate level. It is also recommended for technical libraries and as a primary reference for IR practitioners.
