Research on text label classification of science and technology policy based on ESVM
Text label is a kind of text keywords,can simplify extraction of effective information from science and technology policy.For science and technology policy,this paper divides text label into four kinds,such as science and technology investment,intellectual property rights, rural science and technology,tax.Aimed at the shortcoming of the traditional SVM algorithm's label data unbalance,this paper provides a text label classification method of sci-ence and technology policy,w hich combines the Euclidean distance algorithm and ESVM algo-rithm with penalty factor.Finally,with comparing SVM and ESVM,the validity of the pro-pose method on science and technology policy text label is verified.
