Logical reasoning mechanism being suitable for legal expert system

Abstract

The invention discloses a logical reasoning mechanism being suitable for a legal expert system, effectively overcomes the malady that the current legal expert system is based on regulation, and solves the problems that the majority of legal expert systems can not apply judging knowledge for reasoning, only provides simple explanation through regulation feedback, the problems that uncertainty how to stimulate the intuition, experience and reasoning result and other problems are expressed dissatisfactorily. The reasoning mechanism introduces a correlation theory and a method of fuzzy reasoning, abandons simple positive and negative two-value features of traditional logic, regards the logical world into gray level with continuous changes, allows a proposition to be this or that, and exists partial positive and partial negative. The invention provides a more natural and more reasonable operation environment, can describe target system behavior adopting a fuzzy logic technology, imitates people to judge and control behavior technology by cognition and experience, can transform some natural languages into algorithms of computer operation to achieve the purpose of using a simple program to process complex systems which can not be processed or is difficult to be processed by traditional control method. The fuzzy logic correlation theory and method are applied in the legal expert system, can well overcome the shortcomings of knowledge expression, reasoning mechanism and knowledge acquisition and the like of the traditional method in the legal expert system, are more convenient to express numerous uncompleted and inaccurate knowledge and relationship in legal fields, more appropriately describe uncertainty in legal reasoning, makes up for defects of traditional reasoning method, and are suitable for large-scale popularization.

Description

Technical field [0001] The invention relates to the design of a logical reasoning machine of an artificial intelligence legal system, and is especially suitable for the logical reasoning of a legal expert system in complex situations. Background technique [0002] The legal expert system is an important achievement in the application of artificial intelligence technology in the legal field in recent decades. It can not only provide effective legal advice and assistance for ordinary users, but also reduce the labor intensity of judges, lawyers and other professionals, and improve The efficiency and quality of legal work brings huge social and economic benefits. [0003] At present, the existing legal expert system can comprehensively use various representation methods of knowledge, realize the auxiliary retrieval of regulations and cases, legal assistance and auxiliary sentencing of electronic lawyers and electronic judges, and liberate part of judges and lawyers to a certain...

AI Technical Summary

Problems solved by technology

However, due to the particularity of the legal field and the limitations of the theory and technology that the legal expert system relies on when constructing, there are a lot of problems in the reasoning mechanism of the current legal expert system, mainly reflected in the fact that when using commonsense knowledge or A lot of knowledge of experts in empirical thinking is empirical. When experts think, they do not always follow the process of rational thinking. Most of them cannot use judgmental knowledge to reason, and can only provide simple explanations through rule feedback. Unsatisfactory performance on how to simulate the intuition, experience, and uncertainty of reasoning results of legalists, so it is not true intelligence
