Ritwik Banerjee’s Summary

Publications:
- An exploration of pages with high betweenness centrality on the World Wide Web: searching with inexact queries (Int. Conf. on Social Network Analysis and Applications, '09)

Work:
1. Data Mining and Natural Language Processing :
* Worked on Weka.
* Building an automated opinion-based classifier of web documents (news and UGC).
* Noise Elimination and Automatic identification of relevant portions of web-pages.
* Automatic detection of opinion holder from content.

2. Machine Learning Algorithms (all the following were implemented to be scalable to any extent):
* Naive Bayes Classifier
* Support Vector Machines (SVM)
* Hybrid SVM classifiers
* Decision Tree Learners: ID3, C4.5
* k-nearest neighbor (kNN)

3. Built an automating and a testing software for machine learning algorithms. (Think of it as Weka without GUI and without constraints on data size!)

4. Web Crawler: Involves ranking index, horizontal scalability, relevant content extraction, politeness, among several other issues.

5. Algorithm design for process/task automation : Built an automating software for generation of financial reports.

Ritwik Banerjee’s Specialties:

* Algorithms: Natural Language Processing, Data mining, Machine Learning.
* OO Design. Completely language-agnostic. Expertise in Ruby, Perl, Java.
