Abstract: A computer-implemented method for generating a machine-learning model can include receiving, at a computing device having one or more processors, a plurality of reported phone numbers from telephone users, a plurality of posted phone numbers from one or more websites, and transcriptions of messages associated with a plurality of calling phone numbers. The machine-learning model is generated based on these various inputs and stored at the computing device. The model is configured to determine a probability that an unknown phone message is unwanted based on a phone number from which the unknown phone message originated.

Abstract: Method, system, and computer readable medium for detecting the correct phone number format to use based on the user current country and an original country associated with a number to be dialed. This information can be used to allow a user to keep phone numbers in his/her contact list in any common format on his/her country of origin and still allow numbers to be dialed correctly when the user is travelling anywhere in the world.
