Abstract Bad information filtering is conducive to creating a healthy network. A two-level filtering method based on topic and sensitive words is proposed.

In the second stage, according to the frequency, position and sensitivity of sensitive words, the value of bad tendency is obtained by weighting the web text. Finally, taking the text set recognition of bad financial publicity content in the network as an example, the result proves that it can improve the efficiency and accuracy of filtering of bad investment information.
