Education and Affiliations
My topics of interest span several fields including databases, data
mining, machine learning and statistics. My current research
interests are web information extraction, data integration, graphical
models and structured learning.
A good idea about my research interests can be obtained by following
my publications. Some specific problems and
projects on which I have worked are listed below.
- World Wide Tables: The goal of this project is to answer table queries by tapping partially structured sources like tables and lists on the web.
- Information Extraction and data integration: Recently, I have been interested in graphical models
and their use for various extraction and integration
problems. As part of this effort, I have developed a package for
Conditional Random Fields (CRF) that can be downloaded from
- ALIAS: This is a prototype of an interesting
and fairly compelling application of the use of machine learning
techniques like Active Learning to ease the duplicate elimination task
that arise in data cleaning.
- DATAMOLD: is a tool for Information Extraction (more like text
segmentation) using learning based on Hidden Markov Models. This
software has been licensed by a data cleaning consulting company to
solve real-life address cleaning tasks.
ICube: This is a project on which I worked actively between 1999-2001.
It is about enhanced mining of multidimensional OLAP products. A web demo of ICube is available.
New data mining operations: I have worked on temporal data mining. Currently
interested in various multi-class, multi-label and multi-taxonomy
Database mining integration: I have worked on two different aspects of
this problem. First on algorithmic and architectural issues related to
expressing association rule mining algorithm, in a relational engine.
Second, on deploying learnt models within a relational engine so as to
allow close integration with SQL querying and optimization.
- Some past projects (pre-1996): In the
past I have worked on various problems related to multidimensional
OLAP indexing and aggregation computation. My PhD thesis was on query
optimization and scheduling for tertiary memory databases.
- Ancient projects (pre-1991): I got my first glimpse to
research in computer science theory through search problems arising in
rectangle cutting and packing problems.
