Abstract


Based statistical machine learning method and rule-based method combined and applied to the field of biological entity recognition , the use of a typical representative of the SVM statistical learning theory as a concrete realization of machine learning methods , and the use of conversion - based error-driven learning method SVM test results obtained amendments to improve the precision and recall rate of biological entity recognition . This article first by extracting more rich feature set , such as word features , context features , part of speech characteristics , characteristics of the word form the core word feature and stop word characteristics , use the training corpus released by JNLPBA SVM classifier training , and then use the training the SVM model after the announcement of the test corpus JNLPBA identification of biological entities . Training corpus and test corpus statistics based statistical machine learning methods applied to biological entities to identify areas of the existence of some problems , such as learning generalization ability , feature selection problems , the introduction of external resources issues and data uneven , and so on . To further improve the effect of identifying the experimental use of error - driven learning method based on the conversion of the results of SVM annotation correction , transformation rules better linguistic phenomena in biology text mining , to further improve the accuracy of SVM method and Zhao back rate . By the method used in comparison with other researchers , this paper has achieved considerable results with a lot of mature applications .
