As shown in Figure 2, below be specific embodiment of the present invention, concrete comprise following step:
The match pattern figure of step 201, reception user input, and obtain the data plot of storage in advance;
(1) calculates match pattern figure Q at the matching relationship of simulating from antithesis on one's body, note binary relation S;
(2) based on S be among the match pattern figure Q each node to calculate corresponding node of equal value right, for example, for the node of equal value among the match pattern figure Q to u and v, not only need to satisfy (u, v) ∈ S and (v, u) ∈ S just requires the node of node centering of equal value need have identical type, and the node of node centering of equal value has parent node and filial generation node of equal value; For example the node C1 shown in Fig. 3 and node C2 are that node of equal value is right, and Node B 1 and Node B 2 are that node of equal value is right, and node D1 and node D2 are that node of equal value is right;
(3) generate node for each node of equal value that obtains in above-mentioned (2) to generating one, and it is right to replace original node of equal value, for example shown in Figure 4, node of equal value is replaced with generation node C to node C1 and node C2, node of equal value is replaced with the generation Node B to Node B 1 and Node B 2, node of equal value is replaced with generation node D to node D1 and node D2; In addition, if among the former match pattern figure, when between two right nodes of node of equal value, having the limit to be connected, then be that above-mentioned generation node increases the generation limit, example has the limit to connect as shown in Figure 3 and Figure 4 between node C1 and the node C2, then increased the generation limit for generating node C;
(4) it is right above-mentioned generation node to be replaced former node of equal value, obtain the match pattern figure after the minimization, and this match pattern figure has comprised possible generation limit.
In the concrete enforcement of the present invention, when obtaining match pattern figure in the antithesis pattern set of relationship of each coupling on spheroid, can realize by dual mode, the one, can carry out the coupling pre-service optimization of antithesis simulation earlier, and then draw antithesis pattern set of relationship, or directly draw antithesis pattern set of relationship, respectively can be referring to following step 204, or step 205.
The coupling pre-service that step 204, execution are simulated based on antithesis, this step are as the optimizing process of whole matching process, and it is very obvious to optimize effect when data plot is more sparse; What it was concrete can comprise following flow process:
(1) obtains the matching relationship S based on antithesis simulation of match pattern figure Q on data plot G;
(2) for data plot G each the coupling spheroid
Carry out following step (3) to step (7);
(3) S is projected to the coupling spheroid
In, the antithesis simulation set of relationship of obtaining after the projection is S
W, and the filtration of initialization simultaneously tag set filterSet, get it and be empty set;
(4) to S
WIn arbitrarily binary relation (u, v), wherein u is the node among the match pattern figure Q, and v is
Boundary node, and there is node u1 among the match pattern figure Q, u2, satisfy (u, u1) and (u2, u) be the limit of match pattern figure Q, make the descendent node set succ of v (v) gather sim (u1) common factor for empty with the antithesis simulation matched node of u1 simultaneously, or the parent node of v set pred (v) gathers sim (u2) common factor for empty with the antithesis simulation matched node of u2, namely in the coupling spheroid, in the coupling spheroid, do not have corresponding node if satisfy the descendent node of node u among the match pattern figure simultaneously, or the parent node of node u there is not corresponding node among the match pattern figure in the coupling spheroid, then with (u v) adds among the set filterSet;
(5) when filterSet is not sky, take out arbitrary element among the filterSet, the note work (u, v), with (u is v) from S
WMiddle deletion;
(6) to any u2, v2 satisfies (u
2, u) ∈ E
q, v
2∈ pred (v) ∩ sim (u
2) and
With (u2 v2) adds filterSet;
(7) to any u1, v1 satisfies (u, u
1) ∈ E
q, v
1∈ succ (v) ∩ sim (u
1) and
With (u1 v1) adds filterSet; Go to the execution of step (5) step;
If exist the some u among the match pattern figure Q to satisfy
Be that some u among the match pattern figure does not exist the node that satisfies antithesis simulation constraint condition in the spheroid in coupling, then empty
In addition, delete all in the above-mentioned steps (5) and do not met node and the antithesis matched node thereof of antithesis simulation constraint condition, removed the new ineligible matching result that the deletion processing brings in the step (5) in step (6) and the step (7).After executing above-mentioned steps, export binary set (S at last
W, v).
If carried out above-mentioned step 204, then can be from obtaining binary set (S at last
W, take out S in v)
W, mating spheroid as match pattern figure
In antithesis pattern set of relationship; Do not go up l if carry out
Q(u)=l
G(the v) step of stating 204, then for match pattern figure Q, and each coupling spheroid
All carry out following step:
(1) for each the node v among the match pattern figure, initialization its antithesis simulation matched node set sim of coupling in the spheroid (v), node u wherein in the coupling spheroid a bit, namely
Node u is identical with the type of node v, satisfies namely
With;
(2) for each node among each match pattern figure, execution in step (3) if all nodes are all finished, skips to step (6) to step (5) successively;
(3) if exist limit (v, v ') to belong to match pattern Q, i.e. (v, v ') ∈ E
Q, make to arbitrary node u ∈ sim (v), coupling spheroid
In all do not exist limit (u, u ') to satisfy u ' ∈ sim (v '); Then with u from sim (take out v), namely sim (v) :=sim (v) u}, this step is that the descendent node v ' that determines v among the match pattern figure Q does not exist matched node in the coupling spheroid;
(4) if exist the limit (v ', v) belong to match pattern figure Q, namely (v ', v) ∈ E
Q, make to arbitrary node u ∈ sim (v), coupling spheroid
In all do not exist the limit (u ', u) satisfy u ' ∈ sim (v '); Then with u from sim (take out v), namely sim (v) :=sim (v) u}, this step is that the parent node v ' that determines v among the match pattern figure Q does not exist matched node in the coupling spheroid;
(5) if
Be that node v does not exist the node that satisfies antithesis simulation constraint condition in the coupling spheroid, then return empty set
And termination is withdrawed from execution, otherwise is gone to step (2) the execution of this coupling spheroid;
(6) upgrade antithesis pattern set of relationship S
W, this S
WComprise that all satisfy the node set of antithesis simulation constraint condition, i.e. S in match pattern figure and the coupling spheroid
w:={ (v, u) | v ∈ V
q, u ∈ sim (v) }, return S
w
In the above embodiment of the present invention, wherein for step 205 and step 206, can obtain match pattern figure antithesis pattern set of relationship thereon to different coupling spheroids successively, and obtain the coupling subgraph, therefore, before execution in step 205, can further judge whether not carry out in addition the coupling spheroid that above-mentioned steps 205 and step 206 are carried out matching treatment, if.Then also need again execution in step 205 and step 206, otherwise can export the coupling subgraph of acquisition.
