Semantic Enhancement

Lawmakers and privacy advocates are concerned that a powerful new data searching tool being tested by the Department of Homeland Security could pose a threat to Americans' privacy as it sifts through mountains of information for patterns that might reveal terrorists.
Called ADVISE — for Analysis, Dissemination, Visualization, Insight and Semantic Enhancement — the program is capable of linking and cross-matching material from websites and blogs to government records and personal data.
Homeland Security has quietly been developing the ADVISE program since 2003, the same year another powerful data mining program at the Pentagon called Total Information Awareness was scuttled over privacy concerns.
Some leading lawmakers believe Congress needs to scrutinize these programs carefully, fearing data analysis capability is advancing so quickly that government oversight can't keep pace with it.

Doublespeak is most reminiscent of Orwell's "newspeak" when it is used by a government agency to cover up something unpleasant. The government may find the need to talk about something that has negative connotations to large portions of the public, and avoids backlash by replacing the term with a new one that most people will not recognize as the same thing. Thus "area denial munitions" means "landmines", "physical persuasion" and "tough questioning" mean "torture", and "operational exhaustion" means "shell shock". The government even employs doublespeak against its own, for example the U.S. Army's recruitment motto is "Be an Army of One." This appeals to rugged individualism, yet the reality of soldiering is that of submission to authority and the following of orders without question. - Wikipedia
