Googel acquired MetaWeb today. The MetaWeb is a semantic search infrastructure. MetaWeb also has FreeBase database that has about 12 million topics and entities that can be person, place, books, films, products, etc. Its like a wikipedia information however in a structured format and can be available for semantic search. The Freebase can be downloaded or access via APIs. As of now, Google would allow the continuation. However, any restrictions on usage / licensing changes would impact the applications based on the same. Anyway, it is clearly seen that Google is being pressured to provide more relevant searches and this is its attempt to acquire technology as well as talent in the field.
