HI,

An interesting paper is "10 CHALLENGING PROBLEMS IN DATA MINING RESEARCH" by Qiang Yang and Xindong Wu.

http://www.cs.uvm.edu/~icdm/10Problems/10Problems-06.pdf

It identifies top 10 major research problems in data mining:
- Developping an unified theory of data mining
- Scaling up for high dimensional data and high speed data streams
- Mining complex knowledge from complex data
- Data Mining in a network setting (social networks...)
- Mining in an for computer networks (high speed mining of high speed streams
- Distributed data mining and Mining Multi-agent data
- Data mining for biological and environmental problems
- Data Mining process-related problems
- Security, privacy and data integrity
- Dealing with non-static, unbalanced and Cost-sensitive Data

I think we should all read this carefully.

Thanks for sharing. Very interesting article.
