概率逻辑的研究

The Study of Probabilistic Logic

在人工智能科学中,不确定推理扮演着一个非常重要的角色,而其表示方法也很多,文中要讨论的概率逻辑便是其中之一,它是以逻辑表示为基础进行概率推理。首先,从知识表示和概率定义两个不同的角度系统地介绍了概率逻辑的产生及其发展,然后总结了它的一些基本概念,在此基础上给出了求得一致可能世界的一种逻辑系统,为概率逻辑的发展起到推动作用。最后将概率逻辑同与之容易混淆的模糊逻辑加以区分,且提出了概率逻辑的价值及其展望。

In artificial intelligence science,the uncertain reasoning plays a very important role,and there are many methods of it. The one of the methods is probabilistic logic which will be discussed in the article.Probabilistic logic is the probabilistic reasoning on the basis of logic representations. Firstly, introduced systemically the generation and development of probabilistic logic from knowledge representation and probabilistic definition. Then summarized some basic notions and gave a logic system to obtain a consistent possible world. So it prompted the development of probabilistic logic. Also distinguished it from fuzzy logic which was easy to be confused,and analysed the valuation and perspective, thus made us more clear to recognize the probabilistic logic.
