This method combines the real-time filter with the call-bill analysis to filter the garbage notes (GN). It raises the intercepting rate of the GN supervision center and lowers the error judgment rate. Its advantages: 1) The Chinese key words adopt the blur-pinyin / keyword matching mould-board technique to effectively clear the interfere info in GN. 2) According to the behavior character of GN, this method regulates dynamically the user trust levels, integrates the Garbage Degree Value of notes to judge the note genus. 3) The parallel real-time filter programs run on the multi-core hardware platform to reduce the influence of the note supervision center on the processing ability of the note business center. 4) The new strategy of note sorting and processing is: letting legal notes pass, intercepting GN, attaching runner's prompt on the question note, then letting it pass. 5) This system adopts Beyes method to learn off-line the note specimen and generates the GN keyword dictionary.
