The invention relates to the technical field of
network security and
data processing, and discloses a violation short message recognition method and
system based on deep semantic understanding, and the method comprises the steps: firstly cleaning an original short message, generating a mixed embedding vector through characters, sub-words and
pinyin, and carrying out the recognition of the violation short message; then
processing through a double-layer detection engine, wherein the first layer utilizes rules and a lightweight model for rapid preliminary screening; in the second layer, for suspected samples, a double-
tower fusion
neural network architecture is adopted, local and global features are combined, fusion is carried out through a gating unit, and a large
language model is input to carry out deep semantic reasoning. The
system executes strategies such as interception or flow limiting according to the risk
score, and realizes model iteration through a dynamic
knowledge base and
incremental learning. According to the method, the
resource consumption and the detection precision are balanced through the layered architecture, the antagonistic variants are effectively identified by utilizing multi-dimensional
feature fusion, and the method has the
adaptive evolution capability for a novel violation mode.
