Abstract：Based on years of massive manual indexing data, this paper constructs a natural language classification thesaurus with Mutual Information (MI), Chi-Square (χ2) and Maximum Likelihood Estimate (MLE) to analyze the corresponding relation between keywords and Chinese Library Classification Codes. The performances of the Keywords-Chinese Library Classification Codes Integrated Thesaurus used for automatic indexing of sci-tech literatures are tested by close and open testing.
