Abide card medicine is decision-making system (below)
Software of medicine of family approach force (Shenzhen) limited company Likewei
Medical of card of four, abide is decision-making the system implements plan (brief)
One, design train of thought
1) basis: Abide card medicine and artificial intelligence are decision-making system, both without conflict, can bring out the best in each other.
2) is told from the angle of computer software, medical artificial intelligence basically is the decision-making system that is based on built-in knowledge base, it can complete a few of abide card medicine main step, outside the exterior retrieval that what remove document material, OK interiorly is finished. So, the one part that is artificial intelligence knowledge base will be spent inside the exterior resource of abide card medicine, build with the means of artificial intelligence, use and managing is an important improvement, make exterior evidence resource can knowledge base of add up interiorly, have plan as a whole, have integration analysis, have key move, accord with a hospital to build a target, build knowledge base and match well of evidence of abide card medicine.
3) makes the abide card medicine henceforth carries out faced problem, it is to put forward temporarily no longer, search temporarily, temporarily analysis, individual make, approve system of quantities to make however, store reserve, improve efficiency, shorten scientific research of time, help, promotion is civilian.
4) realizes the practice mode of abide card medicine with the methodological interiorly of medical artificial intelligence, improve the practice efficiency of abide card medicine, reduce operation difficulty, drive abide card medicine whole process of perforative diagnosis and treatment; Strengthen medical artificial intelligence with train of thought of abide card medicine at the same time the reliability of decision-making knowledge base and from adaptability.
2, abide card medicine diagnoses stencil
1)Set is between diagnostic element C and disease D, it is to use former gather to show latter commonly, namely: The real significance of disease Dj explains jointly by Ci of a group of diagnostic element. Because Ci of this group of element is put in the internal composition of mutual correlation, call ‘ diagnostic stencil ‘ .
2)Either disease Dj is OK many more aleatoric diagnostic element Ci, the diagnostic element Ci of Dj of each corresponding disease has the unit structure of an element necessarily; Such, either disease can have random the unit structure of many element Ci, diagnose stencil namely, see a picture one.

3)Of diagnostic stencil form: Authority P states a priori of stencil interior concerns inside, authority R states stencil is exterior outside the prior probability that happen; Frequency F records element to use a situation correctly in this locality outside, undertake correction to R; Invariable K expresses F to differ constant to R amendatory class.
3, knowledge base and decision-making engine
The construction method of knowledge base of medicine of 1) abide card, move is as follows:
A. Build library list: Those who set a database ‘ diagnostic element is expressed ‘ , basically be being formed is Ci of vocabulary entry internal code; Diagnostic stencil and ill name are strict, build ‘ the disease is decision-making watch ‘ , set a field: Ill name structure of internal code of vocabulary entry, vocabulary entry, diagnostic unit. See a picture 2:

B. Decision-making knowledge base is basic and algorithmic: To diagnostic element the watch inputs corresponding content; To the disease decision-making watch inputs corresponding content; Initialization; Make choice of needs to build the disease name of diagnostic stencil; Spread out diagnostic stencil editor; The choice diagnoses element to express vocabulary entry of medium likely essential factor, buy enters the proper place of decision-making editor, relapse so, till satisfy a requirement.
2) builds based knowledge base decision-making engine, basic and decision-making technological process sees a picture 3:

Five, the advantage of decision-making system mixes abide card medical science the effect
Express below 1) one, system of medicine of card of current Western medicine, abide and abide card medicine 3 kinds of decision-making means have comparative:
Express one: Decision-making means contrasts watch

Medical of 2) abide card is decision-making the system is to belong to medical artificial intelligence to assist decision-making category, introduced multinomial innovation idea, excel before binary tree decision making techniques, Bayes decision making techniques, exceed text to link decision making techniques to wait; The decision-making query means of this system is batch processing form, alternant and respondent data capacity is large, realized much passageway collateral derivation, can shorten greatly interactive time.
Medical of 3) abide card is decision-making the system made full use of decision-making knowledge base, the initiative information content that makes two-way and respondent place needs is very little, lowered the first when cause by input difficulty use threshold thereby.
Medical of 4) abide card is decision-making the system made full use of decision-making knowledge base, make two-way and respondent, guide, contrast, conclude form emulate decision-making thinking, make whole and decision-making process can one pace approachs decision-making end, reflect decision-making intelligence to change a feature truly.
What 5) system comes true is flexible knowledge base frame, facilitating knowledge base makes large area safeguard revise, suit medical knowledge can accumulate sexual growth, conduce to knowledge base follow exterior medicine development undertakes the gender is built dogging.
6) uses computer method to blend in the decision-making mechanism of abide card medicine the decision-making plan of medical artificial intelligence, not only the evidential quality that enhanced intellectual data, raised decision-making efficiency and accuracy, at the same time the aristocratic application character abide card medicine pulls civilian to turn application.
Medical of 7) abide card is decision-making the system introduces mechanism of abide card medicine medical artificial intelligence, perhaps said to realize mechanism of abide card medicine with artificial intelligence, two kinds of technologies are mutual and shirt-sleeve, promote each other, develop the whole that drives medical informatics.
