data mining

the automated (computerized) examination of a large set of observations or measurements, particularly as collected in a complex database, in order to discover patterns, correlations, and other regularities that can be used for predictive purposes. Although a relatively new discipline, data mining has become a widely utilized technique within commercial and scientific research. For example, retailers often use data mining to predict the future buying trends of customers or to design targeted marketing strategies, whereas clinicians may use it to determine variables predicting hospitalization for psychological disorders. Data mining incorporates methods from statistics, logic, and artificial intelligence.

sedative, hypnotic, and anxiolytic drug

sedative, hypnotic, and anxiolytic drug

any of a group of CNS depressants that have been developed for therapeutic use because of their calming effect (i.e., sedative) and ability to induce sleep (i.e., hypnotic) and reduce anxiety (i.e., anxiolytic). They include the barbiturates, meprobamate, and the benzodiazepines. At low doses, these drugs are prescribed for daytime use to reduce anxiety; at higher doses, many of the same drugs are prescribed as sleeping pills. Although efficacious when used sparingly, over the long term all induce marked tolerance, and cessation of use can precipitate potentially life-threatening withdrawal phenomena. Acute abuse can yield dangerous intoxication effects, and chronic abuse can cause a range of serious, irreversible conditions.
