Data mining is an extraction activity with the goal
of discovering hidden facts contained in databases (Dalkir 465). Using “machine learning, statistical
analysis, modeling techniques and database technology, it can reveal patterns
of behavior that will allow future behavior to be predicted (Dalkir 272). It is significant in the areas of “market
segmentation, customer profiling, fraud detection, evaluation of retail
promotions, and credit risk analysis” (Dalkir 465). I liked the example in our text of the
relationship between the purchase of beer and diapers by new fathers.
Large numbers of inputs over long periods of time
can be used to forecast future results and can be as simple as a decision tree
or regression analyses or can be very complex models (Dalkir 272). I think the issue of privacy and data mining
is an interesting one. Shoppers are
happy to give up their privacy to stores with free rewards memberships. Stores then know when and where you shop,
what you buy, and how much you spend in exchange for small discounts. I don’t think that shoppers understand how
much information can be collected and stored about them. I watched a YouTube video from SAS, a company
that does data mining and analytics for business solutions. It makes the point about the huge amounts of
data available about your “stakeholders, operations, suppliers, and
customers”. They promise to “chew
through data” to discover “trends, patterns, and relationships” and apply
analytics so you can make business decisions based on facts (SAS). The comments after the video were interesting
in that a person points out that data mining can also be used for spyware,
malware and virus based activities.
Other uses for data mining have been in the area of
health care. The HIPAA or Health
Insurance Portability and Accountability Act of 1996 addressed, among other
things, the privacy of health information that became possible only after data
mining methods made it possible to discover and patients had not consented to
the disclosures. One current related
issue has resulted in a lawsuit by customers against Walgreens for selling
prescription information to data mining companies even though it no longer
identified individuals (Harlow). I think
there was fear that individuals could later be re-identified and that the
people had not consented to allow Walgreens to disclose their health
information.
I read about another interesting use of data mining in a story run by the Associated Press
in August that revealed that Mitt Romney was using a “secretive data-mining
project to identify new and wealthy donors” (Politico). The information was from consumers and the
data was used like businesses looking for sales leads based on past consumer activity. With the large amounts of information in
the world today, data mining will continue to be an important method of
managing knowledge.
