Abstract: The present disclosure introduces a method, an apparatus, and a system of filtering information. In one example embodiment, a message is received and a text is retrieved from the message. It is then determined whether a filtering container includes a sample that is similar to the retrieved text. If a determination result is positive, a new sample is created for the retrieved text and the sample is added to an attribution sample database of the filtering container and the message is not transmitted. If a determination result is negative, a new sample is created for the retrieved text and the sample is added to a new sample database of the filtering container and the message is sent. The present techniques may reduce the probability of missing filtering information, improve the successful rate of filtering information, and improve the data processing efficiency.
