Balancing between over-weighting and under-weighting in supervised term weighting
作者：
Highlights：
• Show the importance of the trade-off between over-weighting and under-weighting.
• Propose a revision of add-one smoothing on delta smoothed idf (dsidf).
• Present three regularization techniques to reduce over-weighting.
• Propose a new supervised term weighting scheme, regularized entropy (re).
