Specific implementation mode
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
Referring to Fig. 1, an embodiment of the present invention provides a kind of method of individual consumer's liveness in acquisition group, including it is as follows
Step：
Group information in S11, acquisition observation time obtains group in the observation time according to the group information
Size of message interval time probability distribution or/and size of message Length Pr distribution.
Wherein, size of message interval time is the interval time of continuous two size of messages record in group, and size of message length is
The character length that size of message records each time is sent in group.
Fig. 2 shows the group information schematic diagrames of group in a period of time obtained.Group information includes the base of group
This information and observation table.Wherein, group's essential information includes by number in group name, group, builds group purpose, observation period, is
No voluntary addition, group's classification, group's brief introduction and group's bulletin etc., wherein group's classification may include level-one class and two level class；It sees
Survey table include the observation date, initiate talk time, terminate talk time, participating in dialogue number, promoter, initiation reason and
Chat topic etc..
Since instant messaging group is that a chat collective such as typewrites so individual consumer sends the heterogeneity of size of message
Speed, frequency of surfing the Net, the enthusiasm etc. of hair message can be reduced significantly, to which the data obtained more have representative
Property, it can more reflect individual consumer's feature in group.Therefore according to the group information of acquisition, it is also necessary to obtain in observation time T
Group message amount interval time probability distribution or/and the distribution of group message amount Length Pr.
In an embodiment of the invention, pass through the probability distribution of the size of message interval time to different group's acquisitions
Or/and the distribution of size of message Length Pr is studied, and finds their probability distribution presentation consistency under log-log coordinate, it is main
Body portion all obeys power-law distribution.
Fig. 3 is group message amount interval time probability distribution example of the group under log-log coordinate.Although each group of notes
Number difference is recorded, the individual consumer member of group is different, but consistency is but presented in the probability distribution under its log-log coordinate, all
Apparent fat clients are presented, i.e., most of transmission size of message interval times are shorter, and a small amount of interval time is very long, removes sagging
Head and long long tail portion, the main body of probability distribution obeys power-law distribution, and power exponent concentrates on the model of about 1.85-2.11
In enclosing.Such distribution characteristics is to meet the potential rule of group mutual-action behavior, and group message, which is propagated, often to be talked about by one
Topic causes, and people initiates topic and causes the common participation of member in group, causes when topic occurs, when disturbance is more and interval
Between it is short, and the silence of some time is had after topic.
Fig. 4 is group message amount Length Pr distribution example of the group under log-log coordinate.Group is used as an Instant Messenger
News tool, interaction has instantaneity, wherein the length of every message generally will not be long.The cumulative distribution of number of characters has certain
Fluctuation, main part can use straight line approximate fits, it can be considered that the cumulative distribution of number of characters also obeys power law, power refers to
Number is between 1.55-2.64.Span scope is larger for interval time, and reason may is that each crowd of composition master
Topic is different, therefore the content for sending message is distinguished.Work together group such as group B, and wherein message is often relatively more brief, and character is few to disappear
Breath accounts for the larger specific gravity of total message count, therefore slope is larger.And interest group A often disappears then because of the sharing contents of interesting property
It is longer relatively more in breath, so as to cause the difference on slope.
In one embodiment of the invention, the size of message interval time according to the group in the observation time is general
Rate is distributed or/and the power exponent size of size of message Length Pr distribution, determines the liveness of group.
Determine the mode of the liveness of group, it can be according only to size of message interval time of the group in the observation time
One of the power exponent size of power exponent size or size of message Length Pr distribution of probability distribution is determining, can also be according to the two
Power exponent size and/or product determine.
In general, the liveness of power exponent Yue great groups is higher, therefore can be according to the size of message interval time of group
Probability distribution or/and the power exponent size of size of message Length Pr distribution, are ranked up the liveness of different groups.According to not
Liveness with group sorts, and preferably goes out a certain number of groups and is studied.
S12, the adjustment change rate after being disturbed by individual consumer and current state and equilibrium state are responded based on group
Between the directly proportional rule of difference, establish group's response model.
Group's response model of foundation, can be described with One first-order ordinary differential equation：
Wherein, y is the current state of group's response, yeFor the equilibrium state of group's response, dy/dt is the tune of group's response
Whole change rate, t are time, 0≤t≤observation time T；β is coefficient, and β can be changed over time in principle, but in order to solve
Conveniently here it is assumed that being constant.
Above formula is the basic model that individual consumer disturbs group's response, can be used for describing group's adjustment and group is flat
Weigh the process that changes with time, which has universal applicability.
S13, the multistep recurrence calculation pattern that group's response is obtained according to group's response model.
Wherein, the multistep recurrence calculation pattern referred to the result of calculation of a upper period as the initial of subsequent time period
Condition simultaneously obtains group's response after multiple periods by period recursion.
It is as follows to solve above-mentioned One first-order ordinary differential equation (1) process：
Due toBring into it is more complex after concrete numerical value, for the ease of solve formula (1) can be rewritten as it is following general
Form obtains：
Obvious formula (2) is First Order Nonhomogeneous linear equation, and general solution is：
Y=e-∫βdt[∫βyee-∫βdtdt+C1] (3)
Wherein, C1It is integral constant in formula.
When by t=0, y=y0Above-mentioned formula (3) is substituted into, the particular solution of the formula (2) is obtained：
In formula, y responds for group, yeFor the equilibrium valve of group's response；y0It is primary condition or initial value, t is the time；β is
Coefficient.β can be changed over time in principle, it is assumed that be constant.
Thus integral term direct solution on the right of formula (4) is obtained
Y=ye+(y0-ye)e-βt (5)
The y=y as t=00
The y=y as t=∞e
Or
Y=(1-e-βt)ye+y0e-βt (6)
Parse formula：
Since individual consumer for equilibrium state actively for group's adjusting stage as a result, regardless of whether will be used as next
The primary condition of a period has an impact simultaneously so that the size of message length and interval time condition pair of early period group's response
Group's response in later stage has an impact, it is thus possible to using the result of calculation of a upper period as the primary condition of subsequent period, and
The responsive state value after multiple periods can be obtained by period recursion.
For this purpose, observation time T is divided into n period, each period is denoted as Vt, and formula (6) is in first period
It can be denoted as
y1=(1-e-βVt)ye1+y0e-βVt (7)
Wherein, ye1For the equilibrium valve of the group within first period.
Accordingly, the 2nd period equally has
y2=(1-e-βVt)ye2+y1e-βVt (8)
Merge (7) and (8) to obtain
y2=(1-e-βVt)[ye2+y1e-βVt]+y0e-2βVt (9)
Thus recursion was obtained to n-th of period
Formula (10) is known as the multistep recurrence calculation pattern of group's response, wherein yeiFor the group within i-th of period
The equilibrium valve of group, Vt indicate observation time T being divided into n impartial period, y0The initial value of group's response.
S14, multistep recurrence calculation pattern and the group the disappearing in the observation time responded according to the group
Breath amount interval time probability distribution or/and the distribution of size of message Length Pr, statistics obtain each individual consumer in the group and exist
Liveness in the observation time.
In one embodiment of the invention, it is specifically included referring to Fig. 5, step S14：
S51, the group size of message interval time probability distribution of initial time and/or is disappeared in the observation time
The distribution of breath amount Length Pr is inputted as initial value in the multistep recurrence calculation pattern, obtains group's response of each period
Value.
A kind of embodiment, can only by group, the size of message interval time of initial time t=0 be general in the observation time
Rate is distributed W0Or size of message Length Pr is distributed R0It is inputted in the multistep recurrence calculation pattern as initial value, i.e. y0=W0, or
Person y0=R0。
A kind of embodiment, can be by the size of message interval time probability of group initial time t=0 in the observation time
It is distributed W0It is distributed R with size of message Length Pr0The sum of inputted in the multistep recurrence calculation pattern as initial value, i.e. y0=W0+
R0。
Another embodiment, can be by the group in the observation time when size of message interval of initial time t=0
Between probability distribution W0It is distributed R with size of message Length Pr0Product inputted in the multistep recurrence calculation pattern as initial value, i.e.,
y0=W0*R0。
After above-mentioned initial value is input in the multistep recurrence calculation pattern, the group that can obtain each period rings
It should value yn, ynFor discrete point, to ynIt carries out curve fitting, the active response curve disturbed to group of individual consumer can be obtained.
In view of the active diversity and complexity for group's change in time and space of individual consumer, individual consumer is active to group
The response curve of disturbance will have a series of different shapes, and corresponding reaction time and adjustment time are also different；We
Reaction time and adjustment time are referred to as the response time, the active response process disturbed to group of individual consumer is known as individual
The active response phenomenon that user develops group.
The characteristic of curve, acquisition group respond reflection stage, adjusting stage and the equilibrium stage of y according to response thus；Its
In：The reflection stage is that individual consumer is active disturbs required reaction time section for group；Adjusting stage lives for individual consumer
Jump adjusts to the period of equilibrium state group；Equilibrium stage is that individual consumer is active maintains equilibrium state for group
Period.
It is the schematic diagram of group's response curve four-stage referring to Fig. 6, Fig. 6.Response curve of the group in observation time T
Four parts can be divided into：1. before disturbance, 2. reflecting stage, 3. adjusting stage and 4. equilibrium stage.
It is S52, long according to size of message interval time probability distribution of the group in the observation time or/and size of message
Spend probability distribution, statistics obtains the active individual consumer of each period and its enlivens the frequency.
For example, in group message amount interval time probability distribution graph, it may be determined that go out in any one period Vt, often
The size of message interval time probability of secondary transmission is how many, and the size of message quantity sent altogether is how many, is which individual consumer respectively
Size of message (active) is had sent, active individual consumer has sent size of message (frequency) several times respectively, it is possible thereby to count to obtain
Active individual consumer and its frequency is enlivened in each period Vt.
Equally, on group message amount Length Pr distribution map, it may be determined that go out in any one period Vt, send out every time
The size of message Length Pr sent is how many, and the size of message quantity sent altogether is how many, is which individual consumer has sent and disappears respectively
Breath amount (active), active individual consumer has sent size of message (frequency) several times respectively, when thus can also count to obtain each
Between individual consumer active in section Vt and its enliven frequency.
Group message amount interval time probability distribution and group message amount Length Pr can certainly be combined to be distributed, altogether
It obtains individual consumer active in each period Vt with statistics and its enlivens frequency.
S53, according to group's response of each period, active individual consumer and its frequency is enlivened, counted
To each liveness of the individual consumer in the observation time in the group.
The step includes two sub-steps：
The first step according to group's response of each period, active individual consumer and its is enlivened the frequency, is obtained
Each alive data of the individual consumer in each period, the alive data include：The individual consumer of each period
Enliven the frequency and corresponding group's response.
Second step does statistical analysis to the alive data of each individual consumer in group respectively in the way of setting, obtains
To each liveness of the individual consumer in the observation time in the group.
Statistical example：In each period, by the group's response for enlivening frequency * and corresponding to the period of individual consumer
Value, obtains individual consumer's alive data of each period；Then the individual consumer of each period in observation time is lived
Jump data carry out cumulative or accumulate to obtain the liveness of each individual consumer.
