Step 1: the structure in the standard card type of tcm diagnosis and the dialectical factor data of standard storehouse
1.1 determining of the standard card type of tcm diagnosis.
1.1.1 with reference to tcm diagnosis and the differential diagnosis in tcm teaching material writing and publish in recent years by differential diagnosis in tcm diagnostic field authoritative expert, national high traditional Chinese medicine universities and colleges' teaching materials " Diagnostics of Chinese Medicine " of People's Health Publisher's publication for example, " practical Diagnostics of Chinese Medicine ".
1.1.2 will get its total standard card type structure standard card type database with reference to the processing of occuring simultaneously of the TCM Syndrome Type in the teaching material.Choose with reference to total TCM Syndrome Type in the part of the differentiation of disease according to pathological changes of the viscera and their in the teaching material, structure standard card type input database.The differentiation of disease according to pathological changes of the viscera and their partly is divided into six big systems: liver and differentiation of gallbladder idsease, and the heart and the differentiation of small intestine disease, spleen and stomach trouble are dialectical, and the lung and the disease of large intestine are dialectical, and kidney and cystipathy are dialectical, and concurrent Zang-Fu syndrome is dialectical.There are some TCM Syndrome Type in each system, and for example liver and differentiation of gallbladder idsease comprise liver blood deficiency, the deficiency of the liver-yin, TCM Syndrome Type such as stagnation of QI due to depression of the liver.
The total certain attributes of card type 1.1.3 settle the standard.Each standard TCM Syndrome Type all has some attributes, and these attributes comprise attribute in the table of card type, fever and chills attribute, actual situation attribute, yin-yang attribute, sick bit attribute, characteristic of disease attribute, interpretation of the cause, onset and process of an illness attribute, cause of disease attribute etc.For example the fever and chills attribute is to accuse of the affiliated fever and chills of type, and sick bit attribute is to accuse of the affiliated position of type.
The field of standard card type database comprises standard card type numbering, standard card type name, the various attributes of standard card type.
1.2 determining of the dialectical factor of standard of tcm diagnosis.
1.2.1 according to standard card type database, will with a kind of demonstrate,prove type in difference with reference to the processing of occuring simultaneously of the dialectical factor in the teaching material, get its total dialectical factor and make up the dialectical factor data of standard storehouse.Some dialectical factors are arranged in each card type, and for example the dialectical factor of card type liver blood deficiency comprises " dizzy ", " yctalopia ", " lustrelessness of the nails ", " extremity numbness ", " the light arteries and veins of tongue is thin " etc.Choose card type liver blood deficiency difference with reference to teaching material in the total dialectical factor data of dialectical factor input standard storehouse.
The field in the dialectical factor data of standard storehouse comprises the dialectical factor numbering of standard, card type under the dialectical factor name of standard, the dialectical factor of standard, the various attributes of the dialectical factor of standard.
Step 2: the judgement of dialectical unit
2.1 the grouping of the dialectical factor:,, carry out dialectical factor grouping according to card type under the dialectical factor according to the dialectical factor data of standard storehouse for waiting to diagnose dialectical factor group.If a dialectical factor belongs to a plurality of card types simultaneously, then the dialectical factor grouping of these card type correspondences has this dialectical factor simultaneously.
The user " hopes, hears, ask, cut " four methods of diagnosis by the traditional Chinese medical science, obtains all symptoms of patient, promptly obtains waiting to diagnose dialectical factor group, with the dialectical system of form input computing machine of selecting or directly importing.For example wait to diagnose dialectical factor group E (5) to form by 5 dialectical factors, E (5)=yctalopia, and lustrelessness of the nails, extremity numbness, the light arteries and veins of tongue is thin, dry and hard excrement }.Dividing into groups according to card type under the dialectical factor in the dialectical factor data of the dialectical system of computing machine search criteria storehouse, obtains belonging to the dialectical factor group e (4) of card type | liver blood deficiency={ yctalopia, lustrelessness of the nails, extremity numbness, the light arteries and veins of tongue is thin }, e (1) | the dry body fluid deficiency of intestines={ dry and hard excrement }.
2.2 the dialectical factor in each grouping is carried out independent assortment, produces dialectical factor group in several card types.
To a grouping e (n) | Q={p1, p2, p3 ... pn}, wherein Q is a card type under the dialectical factor group e (n), carries out combination in any, produces e (n) | any nonvoid subset of Q.Promptly produce e (a) | Q={p1, p2}, e (b) | Q={p1, p2, p3}, e (c) | Q={p2, p3} ... wait the dialectical factor group in several card types Q, a＜=n wherein, b＜=n, c＜=n.
2.3 if dialectical factor group energy satisfies all properties value of this card type in certain card type, judge that then dialectical factor group in this card type forms the dialectical unit of this card type.
Each card type all has a property value to various attributes, and identifies and describe a card type uniquely with property value set.This attribute value set share a data structure C S|Q={u1, u2, u3 ... un} represents that wherein Q is certain card type, and u1 is an attribute in the table of card type Q, and u2 is the fever and chills attribute of card type Q, and u3 is the actual situation attribute of card type Q ... un is n the property value of card type Q.CS for example | the deficiency of the liver-yin={ " lining ", " heat ", " void " ....
Dialectical factor group is made up of some dialectical factors, and the property value set of each dialectical factor verification type all has one group to be worth accordingly, uses data structure CS|p={w1, w2, w3 ... wn} represents that wherein dialectical factor p is the dialectical factor of card type Q, and n represents that card type Q has n kind attribute.If dialectical factor p satisfies the u1 attribute, w1=1 then, otherwise w1=0; If dialectical factor p satisfies the u2 attribute, w2=1 then, otherwise w2=0, by that analogy.If dialectical factor group e (n) | Q={p1, p2 ... pn} calculates CS|p1={w11, w12, w13 ... w1m}, CS|p2={w21, w22, w23 ... w2m} ... CS|pn={wn1, wn2, wn3 ... wnm}, m represent that the card type has m attribute, and n represents that e (n) has n the dialectical factor.If dialectical factor group e (n) | i attribute of Q verification type with value for Sum_CS (e (n) | Q, i)=∑ wi=wi1+wi2+ ... win, ∑ represent summation.Sum_CS (e (n) | Q, i) i the attribute of expression dialectical factor group e (n) verification type Q and be worth, calculate all properties with value amass Mum_CS (e (n) | Q)=п w=∑ w1* ∑ w2 ... ∑ wm, п represents quadrature, and Mum_CS (e (n) | Q) all properties of expression dialectical factor group e (n) verification type Q is long-pending with value.If Mum_CS (e (n) | Q)＞=1, judge dialectical factor group e (n) | Q can constitute the dialectical unit of card type Q, and this dialectical unit is expressed as R[e (n)] | Q.
For example with attribute in the table, fever and chills attribute, actual situation attribute, sick bit attribute, characteristic of disease attribute description and the sign card type deficiency of the liver-yin, the CS| deficiency of the liver-yin={ " lining ", " heat ", " void ", " liver ", " deficiency of Yin " }, e (2) | the deficiency of the liver-yin={ two xerophtalmias, hectic fever }, CS| two xerophtalmias={ 1,1,0,1,0}, CS| hectic fever={ 1,1,1,0,1}, so e (2) | all properties of the deficiency of the liver-yin and long-pending Mum_CS value (e (2) | the deficiency of the liver-yin)=1, judge e (2) | the deficiency of the liver-yin={ two xerophtalmias, hectic fever } can constitute dialectical first R[e (2) of the card type deficiency of the liver-yin] | the deficiency of the liver-yin={ two xerophtalmias, hectic fever }.
Step 3: the decomposition of dialectical unit
3.1 the detection of similar dialectical unit: the attribute of all dialectical units of contrast card type, if certain dialectical unit is identical with value for the attribute of all properties of this card type with another dialectical unit, think that then these two dialectical units are similar dialectical unit.
If two dialectical factor group e (n) | Q, e (m) | Q constitutes dialectical first R[e (n) of card type Q] | Q and R[e (m)] | Q, m wherein, n is respectively the dialectical factor number of two dialectical factor groups.Calculate dialectical factor group e (n) | all properties of Q with value Sum_CS (e (n) | Q, 1), Sum_CS (e (n) | Q, 2) ... Sum_CS (e (n) | Q, k), wherein k represents that card type Q has k attribute.In like manner calculate dialectical factor group e (m) | all properties of Q with value Sum_CS (e (m) | Q, 1), Sum_CS (e (m) | Q, 2) ... Sum_CS (e (m) | Q, k).If exist certain attribute and value Sum_CS (e (n) | Q, i)=Sum_CS (e (m) | Q, i), wherein 1＜=i＜=k then judges dialectical first R[e (n)] | Q and dialectical first R[e (m)] | Q belongs to similar dialectical unit.
3.2 the selection of similar dialectical unit: for two similar dialectical units, select the less dialectical unit of dialectical factor number as the dialectical unit that keeps, the more dialectical unit of dialectical factor number is decomposed into some dialectical factors.If the dialectical factor number of two similar dialectical units is identical, then select one at random as the dialectical unit that keeps.
If dialectical first R[e (n)] | Q and dialectical first R[e (m)] | Q belongs to similar dialectical unit, and n＜=m, then keeps dialectical first R[e (n)] | Q, decompose dialectical first R[e (m)] | Q, promptly dialectical factor group e (m) does not constitute dialectical unit; Otherwise keep dialectical first R[e (m)] | Q, decompose dialectical first R[e (n)] | Q, promptly dialectical factor group e (n) does not constitute dialectical unit.
For example dialectical first R[e (2)] | the deficiency of the liver-yin={ two xerophtalmias, hectic fever }, R[e (3)] | the deficiency of the liver-yin={ two xerophtalmias, hectic fever, night sweat } then keeps dialectical first R[e (2)] | the deficiency of the liver-yin, R[e (3)] | the deficiency of the liver-yin does not constitute dialectical unit, and " night sweat " is the dialectical factor.
Step 4: the combination of dialectical unit produces higher dialectical first priority
4.1 the stack of dialectical first priority: the priority of several the non-similar dialectical units in same card type can superpose, priority after the stack is the priority sum of this several dialectical unit, and the priority after the stack is the dialectical group's of unit that forms of these several dialectical unit priority.
The priority of representing a dialectical unit or the dialectical group of unit with RL, RY (n) | Q represents the dialectical group of unit who is made up of n dialectical unit of card type Q, dialectical first R[e (n)] | and the priority RL of Q (R[e (n)] | Q)=Mum_CS (e (n) | Q) * ω, wherein Mum_CS (e (n) | Q) be dialectical first R[e (n)] | the attribute of each attribute and value are among the Q amasss, ω be one greater than 1 self-defined constant.If dialectical first R[e (n)] | Q and R[e (m)] | Q is non-similar dialectical unit, then the priority of these two dialectical units can superpose, the dialectical group RY (2) of unit is formed in the stack back | Q={R[e (n)] | Q, R[e (m)] | Q}, the dialectical group RY (2) of unit | the priority RL of Q (RY (2) | Q)=RL (R[e (n)] | Q)+RL (R[e (m)] | Q).
4.2 exciting of dialectical first priority: after two dialectical elements satisfy shooting conditions and excite, produce a new dialectical unit that belongs to certain card type, and the priority ratio of this new dialectical unit excites the priority of preceding two dialectical elements higher.
If two dialectical elements: the dialectical element X|Q1 of card type Q1 and the dialectical element Y|Q2 of card type Q2, and one of them is dialectical unit or the dialectical group of unit for X and Y, another is dialectical unit or the dialectical group of unit or the dialectical factor, when satisfying shooting conditions, X|Q1 and Y|Q2 can excite and be Z|Q3, wherein Z is the dialectical unit of card type Q3, Q1, Q2, Q3 are card type different between two, the priority RL of Z|Q3 (Z|Q3)=MAX (RL (X|Q1), RL (Y|Q2))+Ω, wherein to get RL (X|Q1) and RL (Y|Q2) bigger one among both for MAX (RL (X|Q1), RL (Y|Q2)) expression, Ω be one greater than 1 self-defined constant.
For example dialectical first R[e (3)] | liver blood deficiency={ lustrelessness of the nails, extremity numbness, the light arteries and veins of tongue is thin }, dialectical factor p| wind formation from blood deficiency={ brothers tremble }, R[e (3) then] | it is a new dialectical first R[e (4) that liver blood deficiency and p| wind formation from blood deficiency can excite] | wind formation from blood deficiency={ brothers tremble, lustrelessness of the nails, extremity numbness, the light arteries and veins of tongue is thin }, the priority RL of this dialectical unit (R[e (4)] | wind formation from blood deficiency)=RL (R[e (3)] | liver blood deficiency)+Ω.
Step 5: the expression of dialectical priority and calculating and comparison thereof
5.1 the expression of dialectical priority: the dialectical priority of a card type by three variablees sign with describe: dialectical first limit priority of this card type, the dialectical factor group priority of the independence of this card type, and numbering that should the card type.
The dialectical priority BL of a card type (MRL, MCL, id) | Q represents that wherein id is the numbering of card type Q, and MRL is dialectical unit or the dialectical group of the unit limit priority of card type Q, and MCL represents the dialectical factor group priority of the independence of card type Q.BL (8,13,1) for example | liver blood deficiency, the dialectical unit of expression card type liver blood deficiency or the dialectical group of unit limit priority are 8, and independent dialectical factor group priority is 13, and the card type is numbered 1.
5.2 the calculating of dialectical priority: the calculating of dialectical priority comprises that dialectical first limit priority of each card type calculates and dialectical factor group priority calculating.Dialectical first limit priority calculating is meant the dialectical unit or the dialectical group of the unit process stack of certain card type and excites the limit priority that can reach; Dialectical factor group priority is calculated the priority of the dialectical factor group of independence that is meant certain card type of calculating.When certain card type did not have dialectical unit to form, dialectical first limit priority of this card type was 0.
(1) calculating of independent dialectical factor group priority: a dialectical factor p|Q of independence who establishes card type Q, calculate CS|p={w1, w2, w3 ... wm}, m represents that the card type has m attribute, independent dialectical factor p | the priority of Q represents with CL, then CL (p|Q)=(w1+w2+w3+ ... wm) * ξ, ξ be one greater than 1 self-defined constant.If independent dialectical factor group is e (n) | Q={p1, p2 ... pn}, the priority CL of then independent dialectical factor group (e (n) | Q)=CL (p1|Q)+CL (p2|Q)+... CL (pn|Q).Calculate the dialectical factor group priority of independence of each card type in this way.
(2) dialectical first limit priority calculates: according to the stack of dialectical first priority with excite computing method, calculate issuable dialectical unit of each card type or the dialectical group of unit limit priority.
5.3 the comparison of dialectical priority: the dialectical priority comparative approach of different syndrome type is: carry out the comparison of dialectical first limit priority earlier, the dialectical priority of the card type that dialectical first limit priority is higher is higher; When dialectical first limit priority is identical, carry out the comparison of dialectical factor group priority again, the dialectical priority of the card type that dialectical factor group priority is higher is higher; When dialectical first limit priority is all identical with dialectical factor group priority, judge that dialectical priority is identical.
For two card type priority BL (MRLa, MCLa, ida) | Qa and BL (MRLb, MCLb, idb) | Qb, earlier relatively MRLa and MRLb, if MRLa＞MRLb, then BL (MRLa, MCLa, ida) | Qa＞BL (MRLb, MCLb, idb) | Qb; If MRLa＜MRLb, then BL (MRLa, MCLa, ida) | Qa＜BL (MRLb, MCLb, idb) | Qb; If MRLa=MRLb, then relatively MCLa and MCLb, if MCLa＞MCLb, then BL (MRLa, MCLa, ida) | Qa＞BL (MRLb, MCLb, idb) | Qb; If MCLa＜MCLb, then BL (MRLa, MCLa, ida) | Qa＜BL (MRLb, MCLb, idb) | Qb; If MCLa=MCLb, then BL (MRLa, MCLa, ida) | Qa=BL (MRLb, MCLb, idb) | Qb.
Step 6: the judgement of diagnosis card type
6.1 calculate the dialectical priority of each card type, the dialectical priority of each card type is sorted, judge the main symptom type of the highest card type of dialectical priority for diagnosis; Beginning downward search from sorting second, if dialectical first limit priority of certain card type is not 0, and should the card type not be father's card type of the main symptom type of diagnosis, then judged the inferior card type of this card type for diagnosis; Input wait diagnose in the dialectical factor group, if certain dialectical factor does not belong to the main symptom type of diagnosis and the dialectical factor of standard of time card type, do not belong to the dialectical factor of standard of father's card type of main symptom type and time card type yet, then determine that it is the double disease of diagnosis.
Calculate the dialectical priority of each card type and the BL that sorts from high to low (MRLj, MCLj, idj) | Qj, 1＜=j＜=t wherein, t is the card type number in the standard card type database, then Q1 is the main symptom type of diagnosis.From BL (MRL2, MCL2, id2) | Q2 begins search, if BL (MRLj, MCLj, idj) | among the Qj, j＞=2, MRLj ≠ 0, and Qj is not father's card type of Q1, then Qj is the inferior card type of diagnosis.Dialectical factor p|Qc diagnoses in the dialectical factor group waiting, and p is not the dialectical factor of standard of Q1 and Qj, neither Q1 and the dialectical factor of standard of father's card type of Qj, judge that then p|Qc is the double disease of diagnosis.
For example wait to diagnose that dialectical factor group={ the light arteries and veins of tongue is thin for lustrelessness of the nails, extremity numbness, cough }, calculate dialectical first R[e (3)] | liver blood deficiency={ lustrelessness of the nails, extremity numbness, the light arteries and veins of tongue is thin }, the dialectical priority BL of liver blood deficiency (8,0,1) | liver blood deficiency, the dialectical priority of liver blood deficiency is the highest as calculated, then card type liver blood deficiency is the main symptom type of diagnosis, and the dialectical factor " cough " is not the dialectical factor of standard of card type liver blood deficiency, then " cough " double disease for diagnosing.
The present invention is by calculating the judgement with the card type based on the dialectical priority of dialectical unit, not only simulated the logical thinking of differential diagnosis in tcm from the low layer to the high level, and significantly reduced needed quantization degree of computation process and statistics link, improved dialectical the objectifying of area of computer aided.The present invention has remedied the deficiency of active computer differential diagnosis in tcm assistant analysis technology, and certain application value is arranged, and can promote traditional Chinese medical science informationization, intellectuality and development of modernization effectively.
