I’ve recently found an interesting data analysis and visualization book: Reactive Business Intelligence: From Data to Models to Insight by Roberto Battiti and Mauro Brunato.

The book explains data analysis concepts in an easy and intuitive way, supported with visual elements. It is freely available for download at http://grapheur.com/static/Battiti-Brunato-RBI.pdf.








There are also funny pictures that depict the subject. Below are two examples of such pictures I find very nice. I hope the authors don’t mind me putting them here.

Figure 17.1 from page 167 – Local search.

Dear colleague:

Our latest book is now printed:

Reactive Business Intelligence. From Data to Models to Insight.
R. Battiti and M. Brunato,
Reactive Search Srl, Italy, February 2011.
ISBN: 978-88-905795-0-9

Full details at the book web site:

http://www.reactivebusinessintelligence.com/

Reactive Business Intelligence is about integrating data mining,
modeling and interactive visualization, into an end-to-end
discovery and continuous innovation process powered
by human and automated learning.
This holistic and unifying goal requires collecting and integrating
topics which are usually dissected in books dedicated to
different areas.

We plan to place figures and slides in the same place very soon.

– Roberto Battiti and Mauro Brunato

I want to introduce a new Data Mining book from Springer: Guide to Intelligent Data Analysis. This book provides a hands-on instructional approach to many basic data analysis techniques, and explains how these are used to solve data analysis problems.

Authors: Michael R. Berthold (University of Konstanz, Germany), Christian Borgelt (European Centre for Soft Computing, Spain), Frank Höppner (Ostfalia University of Applied Sciences, Germany), Frank Klawonn (Ostfalia University of Applied Sciences, Germany).
Publisher: Springer
ISBN: 978-1-84882-259-7

In the book, chapters proceed with examples where KNIME and/or R are used as analysis tools. In addition, two chapters of appendices are dedicated to KNIME and R.

This is an excellent book which contains a very good combination of both theory and practice of data analysis. I strongly recommend this book to data mining researchers. For more information you can visit Springer page of the book.

Last time I used awk to split single cisi.all file into small files like cisi.1, cisi.2 etc. Now, I have needed to join these small files into a single one in a kind of XML format. I have read some tutorials on awk but I am unable to find such a thing as looping over many text files. So, I have used another solution with Windows BATCH file scripting. I have written a little awk program to format and output the content of a given file to some output file. Then, in a batch file, I loop over the files in a directory and for each file, I run the awk program.

Here’s the batch file named JOIN.BAT:

del output.xml
for /r %%X in (dataset\*.*) do (awk -f join.awk %%X)

Here’s the awk file named JOIN.AWK:

BEGIN { print "<DOC>\n<BODY>" >>"output.xml"}
{print $0 >>"output.xml"}
END { print "</BODY>\n</DOC>\n">>"output.xml"}

As you see in the awk program, the content of each file is appended to the file output.xml. On Unix-like systems, you can write similar shell scripts instead of batch file.
