1. A method for semantic data projection, comprising: selecting, from a first database, a first subset of one or more first semantic formulae based on a comparison of respective weights of each of the one or more first semantic formulae and a predetermined threshold weight value; selecting, from a second database, a second subset of one or more second semantic formulae that are semantically relevant to the first subset of the one or more first semantic formulae; and generating one or more third semantic formulae based on the first subset of the one or more first semantic formulae and the second subset of the one or more second semantic formulae.
