The present invention provide a harassing text message determining method. The method comprises the steps of: parsing an original text message content to acquire each word and digit information therein; with the digit information being a reference, calculating a distance from each word to each digit; using the distance as a weight and each word as a dimension, describing the text message content to generate a plurality of corresponding feature vectors; inputting each feature vector into a classification model to obtain an output result; and based on the output result, determining whether the text message is a harassing text message. According to the method and apparatus provided by the present invention, a harassing text message can be determined more accurately, and the probability of intercepting a harassing text message can be increased, and moreover, the probability of intercepting a text message useful to a user is reduced.
