Wherein, u_iRepresent i-th account ID, d in account ID set_jRepresent in the set of the value of sample device attribute j-th Value, f (u_i,d_j) it is account ID u_iPass through the value d of sample device attribute_jAccess the number weight of an application or website, g (u_i,d_j) For account ID u_iPass through the value d of sample device attribute_jAccess the time weighting of the application or website, h (d_j) it is sample device category The value d of property_jReverse correlation weight, wherein, i and j are positive integer.

It should be noted that the weight w (u that the present embodiment is calculated_i,d_j) can apply to it is similar in embodiment one Spend in formula, i.e., w (r.a, r ' .a) value uses the weight that the present embodiment is calculated in the similarity formula of embodiment one.

In the present embodiment, account ID can be obtained according to the access record data preserved in the database of application or website With the following related information between the sample device attribute of the application or the identification equipment of website：As account ID u_iPass through sample The value d of this device attribute_jWhen accessing the application or website, account ID u_iPass through the value d of the sample device attribute_jAccess times d(u_i,d_j), access time lengths sets t (u_i,d_j) and nearest access moment T (u_i,d_j), and account ID set pass through sample The value d of this device attribute_jNearest access moment T (d_j), wherein, T (d_j)≥T(u_i,d_j)。

In the present embodiment, an account ID in gathering for account ID, can according to above-mentioned related information, by with Lower formula determines that the account ID accesses the number weight of the application or website by the value of sample device attribute：

Wherein, u_iRepresent i-th account ID, d in account ID set_jRepresent in the set of the value of sample device attribute j-th Value, d (u_i,d_j) represent account ID u_iPass through the value d of sample device attribute_jThe number of the application or website is accessed, wherein, i and j It is positive integer.

In general, account ID u_iPass through the value d of device attribute_jThe number for accessing application or website is more, then the account Contacting between family ID and the value of the device attribute is stronger, therefore, the weight f (u of access times_i,d_j) can be defined as：f (u_i,d_j)=d (u_i,d_j)；

But account ID intensive access in certain time period sometimes, access times d (u can be caused_i,d_j) abnormal big, in order to prevent this The weight of access times is taken the logarithm, is defined as follows by the appearance of problem, the embodiment of the present application：

In the present embodiment, an account ID in gathering for account ID, can according to above-mentioned related information, by with Lower formula determines that account ID accesses the time weighting of the application or website by the value of sample device attribute：

g(u_i,d_j)=p (u_i,d_j)×q(u_i,d_j)；

Wherein,

Wherein, u_iRepresent i-th account ID, d in account ID set_jRepresent in the set of the value of sample device attribute j-th Value, p (u_i,d_j) it is account ID u_iPass through the value d of sample device attribute_jAccess the weight at the nearest moment of the application or website, q (u_i,d_j) it is account ID u_iPass through the value d of sample device attribute_jAccess the weight of the maximum duration of the application or website, T (d_j) The value d for passing through sample device attribute for account ID set_jAccess the nearest moment of the application or website, T (u_i,d_j) it is account ID u_iPass through the value d of sample device attribute_jAccess the nearest moment of the application or website, max t (u_i,d_j) it is account ID u_iPass through The value d of sample device attribute_jAccess the maximum duration of the application or website, max_k∈[1,m]t(u_k,d_j) pass through for account ID set The value d of sample device attribute_jThe maximum duration of the application or website is accessed, wherein, i and j are positive integer.

Time factor contacts calculating power importance between account ID and the value of device attribute is self-evident, but by It is difficult to catch and quantifies in temporal information, current existing method is not taken time factor into account, therefore, correlation technique In weight be difficult relation between the value for reacting account ID and device attribute dynamic characteristic.

The present embodiment describes the relation between account ID and the value of device attribute using nearest moment and maximum duration.Its In, p (u_i,d_j) the nearest access of account ID is reflected, the value accessed in the recent period is more than access long ago, and therefore, distance is worked as The preceding time is more remote, p (u_i,d_j) smaller.And q (u_i,d_j) reflect account ID u_iPass through the value d of sample device attribute_jAccess when Long influence, time span is longer, illustrates account ID u_iWith the value d of sample device attribute_jRelation intensity it is stronger.

In the present embodiment, the value of sample device attribute can be determined by below equation according to above-mentioned related information Reverse correlation weight：

Wherein, d_jJ-th of value in the set of the value of sample device attribute is represented, m represents the account ID collection of above-mentioned bigraph (bipartite graph) Account ID sum in conjunction, k (d_j) be sample device attribute value d_jThe account ID numbers of association (that is, pass through sample device attribute Value d_jAccess the account ID numbers of the application or website), wherein, j is positive integer.

Usually, associate the value of multiple account ID device attribute node connect the weight on side should be more specific than associating some The weight that the node of the value of account ID device attribute connects side is low, because device attribute fewer interlock account ID Value, it and account ID relation are more binded.Therefore, the value of the device attribute for associating multiple account ID should increase this The ambiguity and uncertainty of the value of device attribute.Using information entropy theory, the entropy of the value of device attribute is defined as：

E(d_j)=- ∑ u_i∈Up(u_i|d_j)log₁₀p(u_i|d_j)；

Wherein, p (u_i|d_j) it is account ID u_iThe value d of associate device attribute_jProbability, according to events of equal probability,k(d_j) be device attribute value d_jThe account ID numbers of association, then the maximum of the value of device attribute Entropy is：

E(d_j)=log₁₀k(d_j)。

In this, calculated to simplify, the present embodiment regards maximum entropy approximation as the entropy of the value of device attribute.Device attribute Value and account ID relation intensity should be inversely proportional with the entropy of the value of device attribute, therefore the device attribute that interlock account ID is more Value, it is weaker with account ID relation intensity.Therefore, the reverse correlation weight of the value for the device attribute that the present embodiment provides is determined Justice is as follows：

Wherein, the sum that m is account ID in account ID set in bigraph (bipartite graph).

In summary, value of the present embodiment based on sample device attributes all account ID, COMPREHENSIVE CALCULATING account ID associations The weight of the value of sample device attribute；The access times Adjustable calculation weight that the value of sample device attribute is passed through based on account ID； The access time Adjustable calculation weight that the value of sample device attribute is passed through based on account ID；Value association based on sample device attribute Account ID number Adjustable calculation weight；So as to realize, the power that equipment Similarity Measure is used in equipment identification process is rationally set Weight.
