Area's construction method is applied to the electric terminal 10 shown in Fig. 1.Below will be exemplified by knowing question and answer forum, with reference to Fig. 2 to the society
The idiographic flow and step of area's construction method are described in detail.
Step S110, its initial effects power is calculated for property value corresponding to each node in initial community network
Value.Alternatively, as shown in figure 3, the initial community network can be realized by following sub-step.
Sub-step S111, choose user's visit capacity in forum and be marked more than the topic of the 3rd preset value.
Sub-step S112, extract user data corresponding to the topic, and the user's phase included in the user data
Mutually concern information architecture forms community network.
Sub-step S113, the node that unallocated to any community is chosen from the community network form initial community network.
In the present embodiment, exemplified by knowing question and answer forum, multiple topics according to present in the forum and access are different
The user situation of topic, the 3rd is more than to user's visit capacity in the forum according to prefixed time interval using crawler algorithm etc. and is preset
The topic of value is chosen, marked.Wherein, the 3rd preset value can be 1200 etc., and the prefixed time interval can select
It is selected as one week, two weeks etc., the present embodiment is not limited herein.
Further, after the user data mark of the 3rd preset value is more than to visit capacity, it can extract marked use
User data, and it is initial according to the user included in user data mutually to pay close attention to the foundation such as the access relation between information or each user
Community network, wherein, the initial community network can have no right network, and the different use of different node on behalf in the network to be oriented
Family, alternatively, the network structure of the initial community network may be, but not limited to, as shown in Figure 4.
Alternatively, the property value can include, but are not limited to user's enquirement number, question answering number, obtain and praise number
And obtain number thanked etc..Wherein, the initial effects power of each node can pass through formula Wi=(0.15 × Nask+0.20
×Nans+0.30×Nagr+0.35×Ntha) be calculated.In formula, WiRepresent the value of the initial effects power of node i, Nask、Nans、
Nagr、NthaUser puts question to number, question answering number, obtains the number praised number and obtain thanks respectively corresponding to node i.
Step S120, initial effects force value and PageRank algorithms based on each node calculate real corresponding to each node
Border influences force value.
It should be noted here that calculating the actual influence force value of each node using PageRank algorithms, the present embodiment is simultaneously unlimited
In the algorithm.
Step S130, the maximum section of actual influence force value is chosen in unlabelled each node from the initial community network
Put as core node to form first community with a node, and the core node is marked.
Specifically, due to there may be node that is marked and being under the jurisdiction of other communities in the initial community network, because
This, when building the first community, unlabelled each node should be chosen from the initial community network and calculates its actual influence power,
First community is built using the maximum node of actual influence power as core node again, now first community is to possess one
The small community of core node, and the community fitness f of first communityC=0, the member node number n in communityc=1, community
Maximum adaptation degreeIt should be noted that in order to make a distinction, the core is tackled when core node is added into first community
Heart node is marked.
Property value in the present embodiment at first based on each node in network determines core node, then is built based on the core node
The problem of mode of vertical first community can avoid node selection from obscuring.In addition, during actual implementation, same initial community can be based on
Network establishes multiple multiple first communities for including a core node simultaneously, and the core node in each community is different.
Step S140, judge to whether there is the adjacent node of first community in the initial community network, if in the presence of,
For each adjacent node, node fitness of each adjacent node relative to first community is calculated；
Specifically, because the core node in first community is that actual influence power is maximum in the initial community network
Node, therefore, after the Primary Construction of the first community is completed, should also judge in the initial community network with the presence or absence of described the
The adjacent node of one community.Where it is assumed that the collection of the first community C adjacent node is combined into V (C), and if V (C) empty set, described
Adjacent node is not present in one community C, then performs step S140.Conversely, if V (C) is not empty set, the first community C
Adjacent node be present, then need to perform step S150 as shown in Figure 5, it is specific as follows.Alternatively, in the present embodiment, the adjoining
Calculation the present embodiment of node is not limited herein.
In addition, if V (C) is not empty set, need to calculate each adjacent node in the V (C) relative to first community
Node fitness.Specifically, in the present embodiment, first according to formulaAsk for the society of first community
Area fitness fC, further according to formulaAsk for adjacent node i node fitnessIn formula, fCFor first
Community C community's fitness,All company's side numbers between first community's C internal nodes,To be saved inside the first community C
All company's side numbers between point and community's external node, α is fitness parameter,Represent node of the node i on the first community C
Fitness, fC+{i}The community's fitness added for the first community C after node i, fC-{i}For the first community C do not add node i it
Preceding community's fitness.
Step S150, judges whether each node fitness meets the first preset value, if satisfied, will then meet that first is pre-
If the adjacent node of value adds first community, and the adjacent node is marked and to adding the after adjacent node
One community is updated.
Specifically, first preset value can be 0, for example, when choosing the adjacent node i of node fitness maximum,
IfThen node i is added in the first community C and plus mark.Now, the first community C community's maximum adaptation degreeCommunity nodes nc=nc+1.If conversely,Then illustrate that the first community C adjacent node is all not belonging to
One community, in other words, now the first community C community's fitness reaches peak value, that is, has obtained a first larger community, the
One community structure is completed.
In addition, actual when implementing, also need to search in the initial community network that institute is no to have the adjacent node not being labeled,
If being not present, optimal community network structure is completed.
Further, for the community network with overlapping community structure, the overlapping nodes between Liang Ge communities are Liang Ge societies
The main carriers of information transmission between area, therefore, if the overlapping nodes ignored in community ignore that it is each intercommunal overlapping
Effect of the node in community's evolution.So, for two stable communities, overlapping nodes other nodes that compare are dissolved into it
In a community possibility it is bigger, its EVOLUTION ANALYSIS to community has great importance, so the overlapping nodes by community
Also the core node collection of each community is addedCan more it be stablized and community network that structure is optimal.This implementation
In example, overlapping nodes are added by core node collection (the first community) by step as shown in Figure 6, it is specific as follows.
Step S160, the first community and each second intercommunal overlap coefficient are calculated respectively.
In the present embodiment, due to being removed in the initial community network outside the first newly-built community, it is also possible to it be present
His multiple second communities, therefore, in order that each community network is optimal, also need to merge the similar community of community network.
Specifically, formula can be passed throughThe first community and each second intercommunal overlap coefficient are calculated, and
Realize that community merges using overlap coefficient as judge index.In formula：OijFor the first community i and the second community j overlap coefficient, |
Si∩Sj| it is the first community i and the second jointly owned nodes of community j, | min (Si,Sj) | it is the first community i and the second society
The nodes of the community of scale is smaller in area j.
Step S170, judges whether each overlap coefficient is more than the second preset value, if being more than, overlap coefficient is more than
Second community of the second preset value is incorporated into first community, and the community network of the first community after merging is carried out more
Newly.
Specifically, second preset value can carry out flexible design according to the actual requirements, and the present embodiment is not limited herein.
Further, since there may be multiple second communities, and more than the second preset value overlap coefficient also likely to be present it is multiple, therefore,
When actually implementing, if more than the second preset value overlap coefficient to be multiple, also can be by being chosen most from multiple overlap coefficients
Big value, then the second community corresponding to the maximum is incorporated into first community, and the first community network after merging is entered
Row renewal.
Step S180, the first community after renewal and remaining each second intercommunal overlap coefficient are calculated, and held
Row judges whether the overlap coefficient is more than the second preset value, if being more than, overlap coefficient is more than into the second of the second preset value
The step of community to the first community, the first community and any one remaining second intercommunal overlapping system after renewal
Number is respectively less than the second preset value, then stops community's combining step, obtain optimal community network.In the present embodiment, community is being carried out
During merging, it is understood that there may be multiple community's combining steps, i.e., only when overlap coefficient is unsatisfactory for merging condition, stop merging step
Suddenly, so as to obtaining optimal community network.
, can walking always by core node collection at this it should be noted that the community's construction method provided in the present embodiment
Determine the forerunner of community under adjacent moment, follow-up thought, community's set G of adjacent time pointtAnd Gt+1In communityCore point collection meet relationAnd at this
It is not community to exist in setOverlapping nodes node, i.e. the node is pertaining only to communitySo communityAnd communityIt there is the Evolvement of forerunner-follow-up.If for example, communityFor communityForerunner, then
It is communityFor communityIt is follow-up thenAnd then it can be provided based on this method and every kind of community is developed
The detailed description of pattern, it is specific as follows.
