Here we identify an important and previously ignored discovery task, which we call data archaeology. Data archaeology is a skilled human task, in which the knowledge(More)
Description logics have a history of success in configuration applications in major companies including AT&T (mentioned in this paper) and the Ford Motor Company. While we have produced a number of commercial configurators, we find a demonstration application to be the best expository tool for describing how description logics can be leveraged effectively(More)
Increased usage of online search by non-logicians has increased the need for a more eeective and friendlier search experience.
