Apple (AAPL +0.4%) has bought BookLamp, a startup that delivered personalized book recommendations by tagging books based on theme and content (i.e. the book equivalent of Pandora's Music Genome Project).
TechCrunch reports the purchase price was in the $10M-$15M range. BookLamp's technology, which is based on natural language analysis, could be used to improve iBooks' recommendation features and categorization.
Swell would complement the music-focused iTunes Radio. It might also serve as a replacement for Apple's oft-criticized Podcasts app (1.5/5 stars in the App Store).
Tim Cook mentioned on the FQ3 CC Apple has closed 5 more acquisitions since the end of FQ2; aside from BookLamp, LuxVue and Spotsetter are the known purchases. The Beats deal is expected to close this quarter.
