Hi Stanam Alag,

Interesting topic and all the best with your promotion. I noticed that you have an ebook as well and how do you envisage preventing/minimising copy right violation due to illegal upload of pdf files to file share sites? Do you use any ebook locking services?

Hi Satnam,

I'm very interested in your book because I'm working on a recommender system right now... It's my first foray into Collective Intelligence / Recommender systems and there's a lot of theory out there to digest.

I'm wondering what algorithms you cover for neighborhood detection, as I've seen some studies showing that the most popular one, the kMeans algorithm, seems to do a pretty poor job on a lot of data sets. Also, what algorithms are there for understanding people having multiple interests and being part of multiple neighborhoods. For example, I'm a Java programmer (obviously) but I'm also a photographer, father, etc. and each of those are separate interest neighborhood groupings.

Thanks!

Hi Jason,

First, congratulations on your book, Webwork in Action -- also from Manning.

Let me answer your question on the kinds of algorithms available. Within the area of collective intelligence, I classify intelligence into three main parts : explicit intelligence (e.g. recommendations, ratings), implicit intelligence (e.g., derived from unstructured text), and derived intelligence, which deals with applying machine learning algorithms to data.

The second part of the book deals with machine learning algorithms. Here, I cover the data mining process, build a text analyzing toolkit, clustering data and predictive analysis. Here, I cover WEKA, which is an open-source framework for data mining in Java and the Java Datamining (JDM) API's developed under JSR 73 and JSR 247. WEKA has an implementation for most of the data mining algorithms. The book provides code for leveraging WEKA and JDM in your application.

Also, there is a chapter on finding patterns from data using clustering. Here, I work through an example of clustering blog entries using k-means and hierarchical clustering algorithms.

Chapter 12 is devoted to the process of building recommendation systems using both content-based and collaborative-based techniques. I also cover three real-world examples: Amazon personalization, Google News personalization, and Netflix.

thanks
Satnam

I recently purchased an MEAP from Manning (Flex in Action) and it was just a plain PDF with your email address on it.

They are not like those from Apress which require you to type a password before you can open it.

I think it's up to the owner to protect his copy, that is if he doesn't want his email to get spammed.

Anyway, welcome Satnam to JavaRanch and looking forward to your interesting book.

 
I agree. Here's the link: http://aspose.com/file-tools
