Linguamatics, a text-mining firm based in Cambridge, UK, said this week that its 2009 revenue exceeded $5 million, which represented 50 percent year-over-year growth.

The privately held firm attributed the increase in revenues to improved sales of software licenses and "associated professional services."

Linguamatics' growth reflects its ability to "respond effectively to expanding demand for text mining" using its I2E software platform, John Brimacombe, executive chairman of Linguamatics, said in a statement.
