How to introduce below according to the model answer of the answer of examinee's paper and examinee's paper and calculate degree of doubting between examinee's test paper.

The present invention is according to the relevant knowledge of information theory, mathematical statistics, in conjunction with education test and appraisal relative theory, the information rate of having constructed the degree of association (plagiarism degree) between the reflection examinee objective item test paper function of doubting, set up the objective item test paper discrimination model of doubting, thereby provide quantitative test examination hall after examination to examine the technological means of discipline situation.

The present invention is directed to 3 kinds of situations handles respectively: (1) is with the plagiarism between the volume kind examinee (volume kind number is used for the mark conversion to be rolled up, and is equivalent to change the identification code of volume); (2) the not conversion between the different volume kind examinees is plagiarized, and promptly plagiarizes the full-filling information point; (3) conversion between the different volume kind examinees is plagiarized, and promptly plagiarizes option.3 kinds of corresponding 3 alanysis objects of situation, the analytic target of the 1st kind of situation is with the objective item answer between the volume kind examinee; The analytic target of situation is not conversion of the objective item answer between the different volume kind examinees in the 2nd; The analytic target of the 3rd kind of situation is the objective item conversion answer between the different volume kind examinees.

In concrete application process, can be respectively handle according to a kind of, any two kinds or three kinds in the situation in above-mentioned 3.

Judge whether two parts of test papers exist the plagiarism phenomenon, main foundation is that objective item is with the answer rate with the wrong answer rate, for analytic target 1 and 3, can be according to objective item with the answer rate with the wrong answer rate, (, need change back original volume to the objective item answer of conversion volume) for situation 3.For analytic target 2, can only be according to objective item with the answer rate.Therefore, in the following description, analytic target 1,3 is classified as one type analyzes.

Determine reasonably to judge that the objective item that exceeds normal category between the examinee is with answer rate and as follows with the method for the critical value of wrong answer rate:

At first introduce the definition of mutual information and weighting mutual information.

Definition 1: mutual information

If X, Y are two stochastic variables, the mutual information between stochastic variable X and the Y is defined as:

$I(X;Y)=\underset{x,y}{\mathrm{\Σ}}p(x,y)\log \frac{Q\left(y\right|x)}{q\left(y\right)}---\left(1\right)$

Wherein, Q (y|x) expression stochastic variable Y is to the transition probability of X, and q (y) represents the probability distribution of stochastic variable Y, p (x, y) joint probability distribution of expression stochastic variable X, Y.

Mutual information I (X; Y) what of the quantity of information from X, obtained of expression Y.Consider other factors, introduce the notion of weighting mutual information.

Definition 2: weighting mutual information I ^*(X; Y)

Weighting mutual information between stochastic variable X and the Y is defined as:

$I^{*}(X;Y)=\underset{x,y}{\mathrm{\Σ}}\mathrm{\ω}(x,y)p(x,y)\log \frac{Q\left(y\right|x)}{q\left(y\right)}---\left(2\right)$

Wherein, and ω (x, y) 〉=the 0th, incident { X=x, the effectiveness weight coefficient of Y=y}.

Weighting mutual information I ^*(X; Y) another kind of statement:

$I^{*}(X;Y)=\underset{x,y}{\mathrm{\Σ}}\mathrm{\ω}(x,y)p(x,y)\log \frac{Q\left(y\right|x)}{q\left(y\right)}$

$=\underset{x,y}{\mathrm{\Σ}}\mathrm{\ω}(x,y)Q\left(y\right|x)p\left(x\right)\log \frac{Q\left(y\right|x)}{\underset{x^{\′}}{\mathrm{\Σ}}Q\left(y\right|x^{\′})p\left(x^{\′}\right)}$

$=I^{*}(P,Q)---\left(3\right)$

Wherein, P represents the probability distribution p (x) of information source, and Q represents transition probability p (y|x).

According to the definition of weighting mutual information, can release conclusion 1: weighting mutual information I ^*(X; Y) be following convex function, I about transition probability Q ^*(X; Y) be continuous function about transition probability Q.

Secondly, introduce the function of doubting, on average degree of doubting and the information rate definition of function of doubting:

Definition 3: the function d of doubting (x, y)

A nonnegative real number d on title A * C (x, y), x ∈ A, y ∈ C is the function of doubting, it represents the dubiety between x ∈ A and the y ∈ C.

Definition 4: average degree of doubting d

If X, Y are stochastic variable, the then on average definition of degree of doubting d:

$\stackrel{\‾}{d}=E\left(d(X,Y)\right)$

$=\underset{x,y}{\mathrm{\Σ}}d(x,y)p\left(x\right)Q\left(y\right|x)---\left(4\right)$

By conclusion 1 as can be known, under the given condition of information source, weighting mutual information I ^*(X; Y) be the following convex function of transition probability.Therefore,, can find a certain transition probability, make weighting mutual information I satisfying under the condition of d 〉=d ^*(X; Y) reach minimum value.For this reason, introduce the doubt definition of function of information rate.

Definition 5: the information rate function R (d) of doubting

The doubt definition of function R (d) of information rate:

$R\left(d\right)=\underset{Q\left(y\right|x)\∈P^d}{\min }{I}^{*}(X;Y)---\left(5\right)$

Wherein $P^d=\{Q\left(y\right|x):\stackrel{\‾}{d}=E\left(d(X,Y)\right)=\underset{x,y}{\mathrm{\Σ}}d(x,y)p\left(x\right)Q\left(y\right|x)\≥d\},$ D is the given limit of on average doubting.

According to the doubt definition of function of information rate, can release conclusion 2: the information rate function R (d) of doubting is dull increasing function.

Further release conclusion 3: the information rate function R (d) of doubting is a convex function down, thereby is continuous function.

According to the definition of above-mentioned introducing, the basic model of doubting of the present invention is proposed.

If stochastic variable X, Y represent two examinee's objective item answers respectively, when answer was A, the stochastic variable value was 0; When answer was B, the stochastic variable value was 1; When answer was C, the stochastic variable value was 2; When answer was D, the stochastic variable value was 3.The identical answer quantity of examinee has reflected and has plagiarized relevant information, therefore got the effectiveness weight coefficient:

Weighting mutual information then:

$I^{*}(X;Y)=\underset{x}{\mathrm{\Σ}}p(x,x)\log \frac{Q\left(x\right|x)}{q\left(x\right)}---\left(7\right)$

Reflected plagiarism degree between the examinee.

Because whether the suspection of plagiarizing between the examinee is come from their answer identical, therefore get the function of doubting:

Then on average degree of doubting is:

$\stackrel{\‾}{d}=\underset{x,y}{\mathrm{\Σ}}d(x,y)p\left(x\right)Q\left(y\right|x)=\underset{x}{\mathrm{\Σ}}p\left(x\right)Q\left(x\right|x)=\underset{x}{\mathrm{\Σ}}p(x,x)---\left(9\right)$

In fact,

It is exactly probability expression with the answer rate.

By the weighting mutual information of preceding surface construction and the function of doubting, can obtain the information rate function of doubting:

$R\left(d\right)=\underset{Q\left(x\right|x)\∈P^d}{\min }\underset{x}{\mathrm{\Σ}}p(x,x)\log \frac{Q\left(x\right|x)}{q\left(x\right)}---\left(10\right)$

Wherein $P^d=\{Q\left(x\right|x):\stackrel{\‾}{d}=\underset{x}{\mathrm{\Σ}}p(x,x)\≥d\},$ D is the given limit of on average doubting.

Above-mentioned information rate is doubted the visual interpretation of function R (d) on average doubting during limit d more than or equal to given with the answer rate between the examinee, plagiarizes the lower bound of degree between the examinee.

Conclusion 4: when 0≤d≤2/3, the information rate of the above-mentioned structure function R (d) of doubting is equivalent to:

Conclusion 4 can be interpreted as: when with the answer probability smaller or equal to p (0) ²+ p (1) ²+ p (2) ²+ p (3) ²The time, promptly there is not the plagiarism phenomenon in the degree of plagiarizing between the examinee smaller or equal to 0; Otherwise, when with the answer probability greater than p (0) ²+ p (1) ²+ p (2) ²+ p (3) ²The time, the degree of plagiarizing between the examinee promptly exists and plagiarizes phenomenon greater than 0.Therefore, will with the critical value setting of answer probability d ^*=p (0) ²+ p (1) ²+ p (2) ²+ p (3) ²

Judge whether exist between two examinees main foundation of plagiarizing phenomenon be two kinds with the answer rate, promptly objective item is with the answer rate with the wrong answer rate.Our purpose is to seek these two kinds of critical values with the answer rate, determines suspicious examinee in view of the above.Provide objective item below earlier with the answer rate with the mathematic(al) representation of wrong answer rate:

Definition 6: examinee i and examinee j objective item k topic are with answer fundamental function δ _Ij ^(k)

If the answer of examinee i objective item k topic is a _Ik, the answer of examinee j objective item k topic is a _Jk, then examinee i and examinee j objective item k topic is with answer fundamental function δ _Ij ^(k)Be defined as follows:

Definition 7: examinee i and examinee j objective item are with answer rate v _Ij

If the objective item answer string of examinee i is a _I1a _I2A _In, the objective item answer string of examinee j is a _J1a _J2A _Jn, the objective item sum of n for comparing between examinee i and the examinee j, then examinee i and examinee j objective item are with answer rate v _IjBe defined as follows:

$v_{\mathrm{ij}}=\underset{k=1}{\overset{n}{\mathrm{\Σ}}}{\mathrm{\δ}}_{\mathrm{ij}}^{\left(k\right)}/n\×100\%---\left(13\right)$

Definition 8: examinee i and examinee j objective item k topic are with wrong answer fundamental function δ _Ij ^{* (k)}

If the answer of examinee i objective item k topic is a _Ik, the answer of examinee j objective item k topic is a _Jk, then examinee i and examinee j objective item k topic is with wrong answer fundamental function δ _Ij ^{* (k)}Be defined as follows:

Define 9 examinee i and examinee j objective item with wrong answer rate u _Ij

If the objective item answer string of examinee i is a _I1a _I2A _In, the objective item answer string of examinee j is a _J1a _J2A _Jn, the objective item sum of n for comparing between examinee i and the examinee j, then examinee i and examinee j objective item are defined as follows with wrong answer rate uij:

$u_{\mathrm{ij}}=\underset{k=1}{\overset{n}{\mathrm{\Σ}}}{\mathrm{\δ}}_{\mathrm{ij}}^{*\left(k\right)}/n\×100\%---\left(15\right)$

In the basic model of front, X represents examinee's objective item answer of doubting, when the objective item of doubting with the answer probability greater than p (0) ²+ p (1) ²+ p (2) ²+ p (3) ²The time, then be judged to be the test paper of doubting.In view of the above, can determine that above-mentioned objective item is with answer rate v _IjAnd objective item is with wrong answer rate u _IjCritical value.

Fig. 2 illustrates the process flow diagram of an embodiment of the test paper of determining in the examination disposal route of the present invention to doubt.

As shown in Figure 2, in step 202, determine the critical value of objective item with the answer rate.

At first, think that examinee's objective item is with answer rate v _IjCan be divided into two parts: substantially with answer rate Ev (objective item is with the average of answer rate) with doubt with answer rate ε _Ij, objective item is with answer rate v between the examinee _IjCan be expressed as:

v _ij＝Ev+ε _ij (16)

Objective item less than Ev does not belong to suspect object with the answer rate, and is on the contrary, just doubtful with the answer rate greater than the objective item of Ev.Therefore, get B ₁={ answer is doubted } then utilizes the thought of frequency approaches probability, can get:

Establish stochastic variable X, Y again and represent two examinee's objective item answers respectively, then the objective item probability expression of doubting with the answer rate is:

Here

Just be exactly to doubt objective item with the answer probability, so objective item with the critical value of answer rate is:

v ^*＝Ev+(p′ ₁(0) ²+p′ ₁(1) ²+p′ ₁(2) ²+p′ ₁(3) ²)P(B ₁) (19)

In step 204, determine the critical value of objective item with the wrong answer rate.

Get B ₂={ answer mistake } then utilized the thought of frequency approaches probability, can get:

$p=\underset{i=1}{\overset{n}{\mathrm{\Σ}}}{p}_i/n---\left(20\right)$

Wherein, n is the objective item sum;

Establish stochastic variable X, Y again and represent two examinee's objective item answers respectively, then the suspicious probability expression with the answer rate of objective item is:

Equally,

Just be exactly to doubt objective item with the answer probability, so, determine the critical value of objective item with the wrong answer rate:

u ^*＝(p′ ₂(0) ²+p′ ₂(1) ²+p′ ₂(2) ²+p′ ₂(3) ²)P(B ₂) (22)

In step 206, according to judging the test paper of doubting with the answer rate with the critical value of wrong answer rate.

Determined that objective item with the answer rate with the critical value of wrong answer rate, judges the test paper of doubting below in view of the above.

For analytic target one, three, comprehensively objective item is judged with the answer rate with the dual critical value of wrong answer rate, i.e. same answer rate v between examinee's test paper _IjWith with wrong answer rate u _IjSatisfy v _Ij〉=v ^*And u _Ij〉=u ^*, then be judged to be the test paper of doubting, not to doubt test paper otherwise be judged to be.

For analytic target two, only judge with answer rate critical value, i.e. same answer rate v between examinee's test paper by objective item _IjSatisfy v _Ij〉=v ^*, then be considered as the test paper of doubting, otherwise not so.

The physical significance of degree of doubting model

At first, be that information source (examinee's first) is sent information in the communication system plagiarizing abstract between the examinee, after the process channel was disturbed, it was very directly perceived and feasible being received by the stay of two nights (examinee's second) then.Secondly, the weighting mutual information is represented the information relevant with plagiarism that examinee's second obtains from examinee's first place, and it has reflected the degree of plagiarizing between the examinee.Function representation is when on average doubting during limit the minimum degree of plagiarizing between the examinee with the answer rate more than or equal to given between the examinee and information rate is doubted.

Information rate is doubted function having connected with the minimum degree of plagiarizing between answer rate and the examinee between the examinee.Therefore,, just can determine when reaching what degree (promptly with answer rate critical value) with the answer rate between the examinee, just have between the examinee that plagiarize may by the analysis of function that information rate is doubted.

Fig. 3 illustrates the system schematic of another embodiment of examination processing system of the present invention.As shown in Figure 3, the examination processing system of this embodiment comprises standard volume memory storage 31, model answer memory storage 32, the examinee's answer deriving means 33 that is positioned at examination processing enter platform 3, the definite device 34 of the test paper of doubting, conversion volume generating apparatus 38 and paper output device 39.Wherein, standard volume memory storage 31, model answer memory storage 32, the examinee's answer deriving means 33 and the test paper of doubting determine that device 34 can for for purpose of brevity, be not described in detail at this referring to the description of corresponding intrument among Fig. 1.Conversion volume generating apparatus 38 is used for that the order of the examination question order of original volume and/or examination question option is carried out conversion and generates the conversion volume, and obtains the answer and the identification code of conversion volume.For example, conversion volume generating apparatus carries out conversion according to transformation matrix to the examination question order of original volume and/or the order of examination question option, generates the conversion volume; Obtain corresponding answer according to transformation matrix; Generate the identification code of conversion volume according to transformation matrix.Identification code, examination question numbering, the stem of examination question, the option standard that sends to that conversion volume generating apparatus 38 will change volume is rolled up memory storage 31 and is stored; The identification code of changing volume is sent to model answer memory storage 32 with corresponding answer to be stored.Paper output device 39 is used to export original volume and conversion volume and identification code thereof.For example, paper output device 39 is a papery paper printing device, prints the corresponding bar code of identification code with the conversion volume on the papery paper of output and the answer sheet thereof; Perhaps, paper output device 39 is the electronics display terminal.

Examination processing system of the present invention has the original volume import feature, can (for example word form) original volume and the automatic import system of model answer, and split into stem, option and model answer, be stored in respectively in standard volume memory storage 31 and the model answer memory storage 32.Conversion volume generating apparatus 38 is upset objective item exercise question and option automatically in proper order at random by rule, and produces the corresponding standard answer.Objective item exercise question and option after the conversion are recombinated, and export to for example word document automatically, generate conversion volume with standard volume equivalent homogeneity by the paper form.

By generating the conversion volume, can make adjacent examinee's paper different as far as possible, thereby reduce the possibility that the examinee makes a profit by back door.
