Logical Analysis Of Legal Expert Systems

The Legal Expert System which is an research branch of Expert system inArtificial Intelligence and the result that Artificial Intelligence seepaged to the legaldomain have obtained the magnificent achievements in the past several decades, butsimultaneously also have many new problems in the development. To Legal ExpertSystem We can research it from the different angle and the different stratification plane. The logic which takes an important role in multitudinous discipline including inArtificial Intelligence Legal Expert System, not only has provided the rich thoughtorigin and the direct instruction for the Legal Expert System 'research, simultaneouslyalso is the key which the new generation of Legal Expert system' researches anddevelopments can be broached through. from the logic angle this article analyzed therelations between Logic ,Artificial Intelligence and the Legal, and pointed out thelogic' important status in the legal expert system; Through the discussing logic inpresent legal expert aspect the and system knowledge expression; inference mechanismand knowledge gain application, promulgated logic's theories and the methods in thelegal expert system research 'vital role. In addition, this article also through the analysisof the question and the reason which appears in the research process of Legal expertsystem, proposed the corresponding countermeasure and pointed out the logic in thelegal expert system research should matter of concern and promulgate the profoundrelation between the legal expert system and the logic in the mutual developing processproduction. The full text altogether divides four parts besides the introduction and theconcluding remark. Among them, The introduction elaborated the legal expert system domestic and foreign researchpresent situation, as well as this article selects a topic goal and significance. The first part of the article is about a legal expert system summary. In this part , theauthor simply introduced the legal expert system concept and the characteristic; thelegal expert system structure and the composition; The author wish readers can have anapproximate understanding to the legal expert system. The second part is about the legal expert system in the logical localization question.In this part of contents, the author through elaborating the relations between logic andlegal as well as logical and the artificial intelligence, has produced the logic'localization in the legal expert system. The third part in detail introduced some related application about logic theories andthe method in the legal expert system, the concrete content includes: Predicate logic inLegal Expert System in knowledge expression application; Indefinite inference of LegalExpert System logical method, induction logic in knowledge in gain application and soon. In the fourth part, the author has discussed some questions of the Legal ExpertSystem which appears in the research. Through analyzing the reason of these questions,the author had pointed out the in-depth reason of these questions produced in Legalexpert systems lay in the logic basic theory 'lagging. regarding this, the author proposedsome corresponding countermeasures from the logic angle, and propose individualopinion about that the logic will be concerned in the future legal expert system research. The last part is the article 'concluding remark, It is not only the brief summary of thispaper's research contents, but also is the prospect forecast about Legal Expert Systemsin future.
