摘要
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。
This paper elaborates the inherent characteristics of the Chinese - English mixed text in the field of life sci- ences. On basis of the cybernetic principle, a new integrated indexing control method, which is conducted to improve the accuracy of automatic indexing for Chinese - English mixed text, is proposed in this paper. The method includes three rel- atively independent and interdependent parts, which are feed - forward control, in - progress control, and feed - back control. Subsequently, the three parts and their integrated application effectiveness for improving the indexing accuracy are introduced in detail. Experimental results show that the proposed new method is successfully applied in indexing of the lit- erature and knowledge database for Hepatitis B subject and the information indexing accuracy is greatly improved.
