Data mining is one of the current hot fields of Computer Science. The new buzzword running around for data mining is 'Knowledge Discovery'.

Humans have limits to processing data, and one problem that many organizations are facing is the huge amount of data that have been collected, and the inability to gather relevant information from it. A lot of research is going into Artificial Intelligence algorithms and statistics to help data mining.

One example of data mining, is looking at a huge Excel spreadsheet, and being able to say, so-and-so will probably buy chocolate pretzels in her next trip to the supermarket.

Another issue with data mining is, how do you present information in such a way, that humans can make effective use of the information? This field needs to work with people who have intimate knowledge about visual perception, so that not only can data be mined, but it would be useful to the human users.
