http://www.almaden.ibm.com/cs/quest/
This website profiles the research being conducted at IBM's Almaden facility, "The Quest project at IBM Almaden Research Center has developed innovative technologies to discover useful patterns in large databases. Our technolgies include mining for association rules, sequential patterns, classification, and time-series clustering. IBM is making these technologies available through its data mining product, IBM Intelligent Miner for Data." It also provides the latest data mining news from IBM.
As can be expected from IBM, a forerunner in IT technology, its website is constantly updated with news and its latest products. It targets corporations that require advance data mining tools. Also includes Technical information for IT professionals to evaluate the products.
IBM's website has the standard navigation lying horizontally at the top of the page, with daughter pages linked on the menu bar vertically placed on the left. The menus are a bit cluttered, but an experienced net/computer user, and we can assume a person looking for datamining tools is relatively experenced in computers should get be aquanted with the website quickly.
