| Abstract: | A method of feature selection and weighting scheme based on text set density is proposed, by which the set containing least elements and representing all variable information of a text can be found. A more reasonable weighting scheme is presented also, with its validity proved by an evaluating criterion, meta-scoring. |

| Keywords: | information retrieval text set density weighting meta-scoring |
