Sorting a Sea
of Information
anaging Gigabytes: Compressing
and Indexing Documents and
Images, Ian H. Witten, Alistair
Moffat, and Timothy C. Bell. Storing,
compressing, and retrieving information
can be challenging and frequently critical to many applications. This book
focuses on the theory, illustration, and
general discussion of this type of information management.
The authors discuss techniques such as block sorting, new
indexing techniques, and new loss-less compression strategies.
They also provide a summary of text and image compression,
indexing, and querying techniques.A history of relevant algorithm development along with a discussion of challenges, pitfalls, and specific solutions is explored.
Information is organized into topics such as compression
and indexing. In addition to diagrams and examples, the
authors use pseudocode to present algorithms in a languageindependent manner.
The book covers text and image compression models, including Huffman, LZW, and their variants; trends in information
management; index creation and compression; performance;
and overall system implementation.
nformation Storage and Retrieval, Robert R. Korfhage.
With a glut of information,
IT professionals are scrambling
for ways to store, retrieve, manage, and dissect it all. This book
tackles the complex problems
facing programmers and system
designers, addressing different
components of the problems; for
example, in addressing querying, the author explores
the familiar Boolean-logic queries along with vector,
weighted, fuzzy, and probabilistic queries. Another
useful section outlines techniques for determining the
similarity of two documents, methods for incorporating user profiles into queries, and nontraditional ways
of presenting query results. The book also presents
measures for rating information retrieval systems.
Other topics include shortcomings in current tools
for Internet searching; an overview of visual information retrieval interfaces; and a discussion of security
issues.The book shows how to handle full-text graphics, video, and audio; and how to distribute these massive databases over networks.

Finding Room
for Gigabytes
How to Create Effective SANs
esigning Storage Area Networks,
Thomas Clark.The sheer volume of
data generated by today’s commercial and academic institutions has created a
storage crisis for IT managers and administrators.
Although larger-capacity disk drives
absorb part of the growing data load, connecting the requisite number of disks to file
and application servers by traditional
means has become increasingly difficult.
Providing the bandwidth to keep up with the users’ requests is
also a continual challenge, as is allocating sufficient time and
bandwidth for backing up data to tape.
Fibre Channel, a standards-based architecture, provides
gigabit speeds over long distances and supports devices in an
extended network. Fibre Channel has become synonymous
with storage area networking because it supports the protocols most optimized for moving data to and from disk and its
inherent networking capabilities.
This book talks to IT managers who are considering
Fibre Channel SANs as a management resource.
Storage area networking represents a major shift from
previous storage models, introducing new networking
products and concepts between servers and storage.The
text does not assume prior knowledge of networking
concepts and discusses the most essential aspects of networking as they apply to SANs. Networking professionals who use SANs as an extension of the local and
wide area enterprise network may also find value in this
book. For these readers, discussions of basic server and
storage concepts should assist in bridging the gap
between networking and storage worlds.
Storage area networking based on Fibre Channel is
relatively new, and this book attempts to achieve a balance between the technical detail required to understand the basic principles of Fibre Channel SANs and
the technology’s most useful features.

Knowledge management (KM)
consulting has revenues of more
than $25 billion worldwide. Information systems and technology are
some of the most in-demand areas
for consulting services, followed
by training, strategic planning,
change management, and human
resources and compensation.
According to this Web site, KM
is the systematic process of finding, selecting, organizing, distilling, and presenting information in
a way that improves an employee’s comprehension in a specific
area of interest.
Knowledge management helps
an organization to gain insight
and understanding from its own
experience. Specific KM activities
help focus the organization on
acquiring, storing, and using
knowledge for problem solving,
dynamic learning, strategic planning, and decision making.

that focus on topics such as
benchmarking and best practices,
business ethics, change management, corporate governance,

he Conference on Information
and Knowledge Management
(CIKM) provides an international
forum for research on information and
knowledge management, as well as
recent advances in data and knowledge
bases. The conference identifies challenging problems in developing future
knowledge and information systems,
and solicits and reviews applied and
theoretical research findings. An
important part of the conference is the
workshops program, which focuses on
research challenges and initiatives.
Topics of interest to the CIKM community include application of knowledge representation techniques to
semantic modeling, development and
management of heterogeneous knowledge bases, automatic acquisition
of data and knowledge bases (especially raw text), object-oriented
database management systems, optimization techniques, transaction management, high performance online
transaction processing systems, and
security techniques.
The conference will also cover performance evaluation, unconventional
applications, parallel database systems,
physical and logical database design,
domain modeling and ontology building, knowledge discovery in databases,
and information storage and retrieval
and interface technology.
Making Tacit Knowledge
Explicit, Japanese Style
he Knowledge-Creating Company:How Japanese
Companies Create the Dynamics of Innovation,
Ikujiro Nonaka and Hirotaka Takeuchii. In this
book, Nonaka and Takeuchii provide an inside look
at how Japanese companies go about creating new
knowledge organizationally.
They point out the two types of knowledge: explicit
knowledge—contained in manuals and procedures—
and tacit knowledge—learned only by experience and
communicated only indirectly, through metaphor and
analogy. US managers seem to focus on explicit knowledge; the Japanese,
on tacit knowledge.And this, the authors argue, is the key to success—the
Japanese have learned how to transform tacit into explicit knowledge.
The authors illustrate the theory of organizational knowledge creation
with case studies drawn from Honda, Canon, Matsushita, NEC, Nissan,
3M, GE, and even the US Marines.
For instance, using Matsushita’s development of the Home Bakery (the
world’s first fully automated bread-baking machine for home use), they
show how to convert tacit knowledge to explicit knowledge: When the
designers couldn’t perfect the dough-kneading mechanism, a software
programmer apprenticed herself with a master baker, gained a tacit understanding of kneading, and conveyed this information to the engineers.
In addition, the authors show that, to create knowledge, the best management style is what they call “middle-up-down,” in which middle managers form a bridge between the ideals of top management and the front
line’s chaotic realities.
