In a move that underscores Internet search giant Google’s attempts to bring about an improvement in the quality of Google+ Circles, the company has recently acquired Katango – the startup behind the development of advanced people-sorting algorithms for enhancing people’s online social interaction.

Katango – which was founded around a year back, and was earlier called CafeBots - was the first firm to be funded by the Kleiner Perkins sFund. The company released an iPhone app earlier this year to facilitate messaging to groups of people across SMS, email and Facebook.

With algorithms for social organization being Katango’s key strength, the company essentially makes use of social cues to bring together the friends as well as colleagues of a user. The technology which Katango uses is notably more advanced that the code that is behind Smart Lists on Facebook.

Google’s takeover of Katango evidently hints that the company intends using Katango’s technology for working out an enhancement of its social network --- more so because the technology will simplify the Google+ Circles’ process of grouping friends into circles.

In a statement to Mashable, a Google spokesperson said that Google was highly impressed by the “innovative approiach” which the Katango team has devised for making the social circles “smarter” for millions of users; and added that the Katango team will be “a great addition to the Google+ team.”
