| Abstract: | Keywords filtering is one of the most common methods in text content filtering and is widely used.Chinese characters are combinations of constituents,and splitting characters into constituents makes keywords filtering difficult.To deal with this problem,a keywords filtering technology based on combination of Chinese character constituents is proposed.It is based on Chinese characters structure library,and uses improved multiple patterns matching algorithm to deal with massive text contents.Tests show that t... |
