摘要
从Shannon开始,已经有很多人讨论了关于信息的测度问题,Shannon等的测度方法主要从信息的功能方面进行了详细的分析,而N auta等的测度方法主要是从信息的组成结构方面来入手。目前,对于统一的信息测度方法的需求日益迫切,钟义信教授从全信息的角度提出了统一的信息概念和测度方法,而丹尼尔.弗德里克也提出了一种全新的方法。本文对以上这些信息的测度方法做了较为详细的介绍和对比,希望进一步推进统一的信息理论的发展,探索信息本质的绝对真理。
From the time of Shannon, there have been so many discussions for the measurement of information. An overview of those theories will be given in this paper. Shannon＇s methods of information measurement belong to the Functional-cybernetic information theories, as well as those of Nauta belong to the Structural-attributive information theories. At present, there is an urgent need for a universal definition and measurement methods of intormation. Professor Zhong Yixin proposed one kind of theory named “Entire Information”, and Doctor Daniel Federico of Universal Berne at Switzerland proposed another kind of new method also. Those theories above will be introduced and compared to each other in ths paper in order to promote the development of information theory and the research for the absolute truth of information essence.
