1. A method for filtering messages comprising:

  • storing a first semantic representation as a first vector corresponding to a first group of messages and a second semantic representation as a second vector corresponding to a second group of messages, wherein the first vector and the second vector were derived from a training corpus which comprised the first group of messages and the second group of messages, and wherein the first group of messages and the second group of messages are different;

    determining a mathematical representation corresponding to an incoming message;

    comparing the mathematical representation corresponding to the incoming message with the first semantic representation and the second semantic representation to obtain a first comparison value and a second comparison value; and

    filtering, by a processor, the incoming message through classifying the incoming message between the first and second groups based on the first comparison value and the second comparison value.
