The Study of Semi-Supervised Learning Algorithm for Web Information Classification

摘要

The paper reports a study on information categorizing based on high efficient feature selection and comprehensive semi-supervised learning algorithm. Feature selections or conversions are performed using maximum mutual information including linear and non-linear feature conversions. Entropy is made use of and extended to find right features commendably with machine learning method. Fuzzy Partition Clustering Method is presented and used to obtain a few labeled samples and some external clusters automatically by measuring the similarity of clustering correlation documents. So classification bases are found for supervised learning. Furthermore, Naive Bayes augment learning is combined to design and learn categorizers. And the approach of estimating the loss of classifying error facilitates to balance the selection of candidates. The all-around learning algorithm can greatly improve the precision and efficiency of web information classification.
