database management systems

This book give you a very usable way in Information Retrieval. Before I read this book, my knowledge in IR was almost zero. But after I finished, I can do an IR project in my grad program. This book also give you a modern concept in IR that you can apply in a real-use. But it requires some knowledge in Computer Science way.

This book suits IT professionals, Computer Scientists, and students in both grad and undergrad.

I have spent several weeks to read this book.

Includes a nice overview of different Information Retrieval techiques. The think I liked most is the uniformity of notation throughout the whole book, that let you compare different approaches withouth getting lost in myriads of mathematical symbols defined in different ways by different authors.
The authors also suggest you the most efficient and effective techniques, so that you can use this information to avoid implementing naive and inefficient solutions.

A very good approach to IR from a computer science perspective. Well organized and easy to read although some chapter could be dry for a novice. Excellent cover of visualization techniques, digital libraries, and web searching from a conceptual point of view. The reference list is large enough (and up-to-date) to keep you busy reading more material for several weeks.
