Dartmouth researchers say that PQS is the best approach

Dartmouth engineers George Cybenko and Vincent Berk think that PQS, or process query systems, are the way to go to make sense of the huge volume of data we collect each day from computer network monitors, video surveillance cameras, financial transaction records, databases of email exchanges, etc. The duo present their case in a paper published in this month's IEEE Computer, the flagship magazine of the Institute of Electrical and Electronics Engineers' Computer Society.

PQS has been an evolving algorithmic and software framework for the past few years. Cybenko and Berk say that PQS is a useful and incredibly powerful tool to quickly analyze credit reports for ID theft, discover attacks on computer networks, and measure activity at, say, national borders, mall parking lots, or wildlife refuge areas.
