分析生命科学领域中英文混编文本的内在特点,基于控制论原理,提出一种旨在提高中英文混编文本的信息自动标引准确性的整合新方法。该方法包含三个相对独立而又相互联系的部分,即前馈控制、中期控制和反馈控制。实验表明,该新方法可以被成功应用在乙肝专题文献知识数据库的标引中,并能大幅度提高信息标引的准确性。 Based on the theory of cybernetics, this paper proposes an integrated approach to improve the accuracy of automatic indexing of information mixed in Chinese and English. The method includes three relatively independent and interrelated parts, namely, feedforward control, medium-term control and feedback control. Experiments show that the new method can be successfully applied to the indexing of knowledge database of hepatitis B subject literature and can greatly improve the accuracy of information indexing.
