Modified DFS-based term weighting scheme for text classification
作者：
Highlights：
• For text classification, different terms have different levels of importance.
• Designing an appropriate term weighting scheme is crucial.
• Distinguishing feature selector (DFS) is a well-known term selection scheme.
• We propose a modified DFS-based term weighting scheme.
• The experimental results validate the effectiveness of the proposed scheme.
