Systems, methods and apparatus for relative frequency based phrase mining

摘要

Example systems, methods, processes, and apparatus identify phrases in electronic information. One or more phrase dictionaries (520) are created from content in one or more electronic documents (310, 505). A relative frequency value is generated for each phrase in each of the one or more phrase dictionaries (520). The relative frequency value for a phrase is based at least in part on a comparison between a frequency of the phrase in the electronic document (310, 505) and a frequency of each individual word in the phrase. One or more phrases are selected based at least in part on a threshold and the relative frequency value generated for each phrase. The selected one or more phrases and the relative frequency values associated with each of the selected one or more phrases are output for graphical display to a user.
