TextDigger, a San Jose, Calif. firm specializing in semantic search and text advertising, announced that it brought in $4.3 million in first-round funding from True Ventures, Intel Capital, CBS Interactive and a handful of angel investors. The money will be used to expand its sales and marketing presence.

The company claims its technology enhances web site findability through major search engines like Google by disambiguating the various meanings of words and by matching queries to relevant sites that may not contain the same language. These functions should help advertisers better target their strategies, increase the scope of their campaigns to sites they may not have thought of otherwise, and generally retain user eyeballs for longer periods of time.

Founded by a group of former CNET employees who worked on linguistic technology, TextDigger has now raised a total $5.8 million in capital since its start in 2007.
