The Medical Expert Diagnoses And Analogous System

This article mainly to introduce the basis and the Jilin University medicine education ministry's cooperation, carried on the design, develops one kind of new medical expert to diagnose the analogous system the method and the design theory.And introduced this new algorithm mathematical model and the rationale.And has made the summary introduction to the use development kit and the system platform.Relied on the support to the medical expert system the artificial intelligence study domain development situation and the main application theory has made the quite detailed elaboration.In the recent several years, the artificial intelligence technology already had the considerable progress in each domain.The artificial function technology already by the reputation was contemporary one of three big most advanced techniques.Artificial intelligence principle and technology, not only can help the people to develop has the intelligent behavior computer system, moreover can cause each kind of practical domain the computer system to be exquisiter and to be nimble, causes the people to use more convenient and freely.The medical diagnosis is a domain which the information processing has bright prospects, but must want to obtain the effective development in this domain, should extricate from the past expert system concept, from the medicine development mainstream direction, diagnosed the treatment from doctor to the patient the actual need to embark, studies the information processing the way which possibly developed in this domain, proposed the new thought, the concept, the method and the technology. This article proposed"the diagnosis treatment support program"new concept and method."The diagnosis treatment support program"is faces the clinical diagnosis to treat the entire process"the human - machine"alternately the metasynthesis system, it aims at is in the clinical scene doctor diagnoses the help to the patient which the treatment the behavior process and doctor request to obtain; It through doctor and the system dialogue, provides the knowledge, the experience, the method, the model for doctor in the diagnosis treatment entire journey which needs helps doctor the accurate thought, achieved reduces the medical expense effectively the goal;"The diagnosis treatment support program"simultaneously completes in the diagnosis course of treatment patient convention supervisory work and so on medical record automatic production, medical record management, curative effect automated analysis and statistics, realizes the patient medical record production and the management automation.In based on in above modular concept foundation, I has made the analogous system which a medical expert diagnoses, this system by gives illness collection by the domain expert, and gives each kind of disease separately the symptom collection, the medical history, the symptom, the symptom, important sorting, the laboratory inspection, the diagnosis method, the treatment plan, the complication and so on the related information.Related information gives which according to the domain expert, developed one to diagnose the analogous system based on the threshold value information judgment medical expert.The artificial intelligence throughout is in the most front which the computer develops.The high-quality machine language, the computer contact surface and the writing processor existence more or less all must give credit to the artificial intelligence research.The artificial intelligence research brings the theory and the insight have directed the computation technology development future direction.The existing artificial intelligence product is opposite in the artificial intelligence application which soon arrives may say not worthy of mentioning, but they indicate the artificial intelligence future.Already and could continue to the artificial intelligence higher level demand to interfere with our work, the study and the life.The mark principle and the joint principle are the artificial intelligence research center quite mature two methods, but these two methods in prompted the human intelligence the mystery and imitate in the human intelligence all to encounter the difficulty which was unable to overcome.How in studies seeks the new scientific method impetus artificial intelligence in the development process, has gradually formed the development thought science research, the multi-disciplinary collaborations, the man-machine union and so on the new method and the way.The expert system is one of artificial intelligence most important applications, its goal is lets the expert who the computer helps or substitutes some domain to a certain extent solve the problem.The expert system is one has the intelligent characteristic computer program, its intellectualized main performance for can imitate the human expert thought in the specific domain to solve the complex question.Therefore, the expert system must contain the domain expert's massive knowledge, has the similar human expert thought inference ability, and can use these knowledge to solve the actual problem. The expert system basic work flow is, the user through the man-machine contact surface answer system inquiry, the inducing equipment each rule condition carries on in the user input information and the knowledge library the match, and is matched the rule the conclusion to deposit to the comprehensive database in.Finally, the expert system will draw the final conclusion to present for the user.MYCIN is one through provides the advisory service to help ordinary internist to diagnose the bacterium infectious disease the expert system.MYCIN also designs for the model production pattern system, by the regular storehouse, the synthesis database and the control system three parts is composed; Only is selects the reversion method based on the rule inference, namely the goal which solves from the question embarks, the search primitive evidence regarding the goal establishment support, and transmits and the computation inference uncertainty.Looked from the KB system composition that, the regular storehouse is the MYCIN knowledge library, the comprehensive database and the control system form the inducing equipment jointly.Among them, the comprehensive database uses to preserve the primitive evidence which the question solves (original state) and the intermediate result.Because at that time not yet appeared the Windows technology, the user interface only provided based on the text question and answer process and the result demonstration.
