Mobile search company Mobile Content Networks has announced that it is buying up the assets of Caboodle Networks, which has developed an open-source “semantic” recommendation platform for mobile users. MCN plans to integrate Caboodle’s open-source-based technology into its search service.  Semantic search, which takes into account such factors as a user’s location, past searches and pre-determined recommendations, has been thought by some to be the next stage in search technology. Indeed in the mobile space a reduction in the number of “taps” that are needed for users to arrive a what they are looking for is definitely the holy grail for companies like Google, Yahoo and AOL. But semantic startups perhaps are having a slow start: Caboodle has been around since 2003 but has only managed to build up it users into the “hundreds.” The terms of the deal were not disclosed. release
