As shown in Figure 1, axis of abscissas is from left to right followed successively by the tetra- IP address libraries A, B, C, D, axis of ordinates is coverage rate.
As seen from Figure 1, in country level coverage rate, the ratio of B address bases is highest, in province and city rank, A
The coverage rate in location library is highest.Coverage rate of the D address bases under country, province, three, city rank is all minimum.So
From the point of view of coverage rate, A address bases are best, and D address bases are worst.
Through the embodiment of the present invention, it has also been found that national coincidence factor, province coincidence factor, city are heavy in different IP addresses library
The height of conjunction rate, and it can be found that the relationship of the height and address base confidence level of coincidence factor.As shown in Fig. 2, axis of abscissas is from a left side
It is followed successively by country, province and city rank to the right side, axis of ordinates is the coincidence factor in each IP address library under rank.From Fig. 2 I
It can be seen that, national coincidence factor, province coincidence factor, the city coincidence factor in 4 IP address libraries reduce successively.Illustrate from whole next
It sees, when the rank that comparison uses is lower, the ratio that 4 address bases overlap is lower, and 4 believable degree of address base are also just more
It is low.
Embodiment 2
The relationship analysis number of the intersection and registration between a kind of library by different IP addresses is additionally provided in the present invention
According to the method for library reliability.In the present invention, appointing from the tetra- IP address libraries A, B, C, D takes three libraries to be compared, i.e., different
The poor proportion that the intersection in arbitrary three IP address libraries is subtracted each other with another IP address library under rank, is shown in Fig. 3, one shares four
Kind situation.
As shown in figure 3, its axis of abscissas be from left to right followed successively by from the tetra- IP address libraries A, B, C, D appoint take three libraries into
Row compares, and axis of ordinates is its difference proportion.
It can be seen that under the country of comparison, province and three kinds of city rank, the coincidence factor of A, B, C address base all compares
It is high, that is to say, that in four IP address libraries, the similarity highest in these three libraries, D address bases are with other three in geography information
Statistically difference it is maximum.Meanwhile under country, province and three kinds of city different stage, the coincidence factor of A, B, C address base also exists
Constantly decline, the coincidence factor of three kinds of databases is rising in three kinds of situations in addition, and this also illustrates the ranks used when comparison
When lower, the ratio that four databases overlap is lower, and the credibility of four databases is also just worse.
Embodiment 3
If appointing from four address bases takes two libraries to be compared, i.e., the friendship in any two IP address library under different stage
The poor proportion that collection subtracts each other with other two IP address library, is shown in Fig. 4, shares six kinds of situations.
As shown in figure 3, its axis of abscissas be from left to right followed successively by from the tetra- IP address libraries A, B, C, D appoint take 2 libraries with
Other 2 are compared, and axis of ordinates is its difference proportion.
A, B coincidence factor highest under country level, and under province and city rank the IP address library of C and B coincidence factor
Highest.Coincidence factor of the D and B address bases under country, province and three kinds of city different stage is all minimum.In addition, at six kinds
In the case of, when the tri- IP address libraries A, B, C are compared with D, coincidence factor will be than comparing between the tri- IP address libraries A, B, C
Coincidence factor want low, this also illustrates three address bases of D address bases and other are larger in the statistically difference of geography information, A, B,
The coincidence factor of tri- address bases of C is higher.
Embodiment 4
In the present invention, additionally provide it is a kind of judge address base confidence level method, this method by assuming that any one
IP address library confidence level is true, it is assumed that the confidence level in any one IP address library is true, by the data overlapped two-by-two, can be obtained
To the confidence level in other three IP address libraries at this time, in the case of then four kinds are assumed, the summation of respective IP address library confidence level, just
It can obtain total confidence level in each IP address library.
As shown in table 1 below, in the case of describing four kinds of hypothesis, confidence level of each IP address library under the rank of city.Table
The true value that lattice assume the numerical value on line for four kinds, i.e., coverage rate of each IP address library under the rank of city, other numerical value are
The current confidence level for assuming other lower three IP address libraries.
The confidence level summation in respective IP address library in the case of assuming four kinds of the embodiment of the present invention, can obtain A, B, C, D
Confidence level of four IP address libraries under the rank of city is respectively 243.80%, 207.08%, 201.97%, 231.14%.Institute
With the confidence level highest of the A address bases under the rank of city, D address base confidence levels are minimum.Can similarly obtain, in country level and
The confidence level height of tetra- address bases of A, B, C, D under the rank of province.
City-level other data reliability % in each IP address library in the case of 1 four kinds of table
| IP address library | A | B | C | D |
| A | 60.04 | 43.00 | 51.51 | 52.53 |
| B | 43.00 | 60.33 | 50.01 | 48.63 |
| C | 51.51 | 50.01 | 81.89 | 60.39 |
| D | 52.53 | 48.63 | 60.39 | 69.59 |
By establishing IP address base value, to contrasting the case where coincidence in four IP address libraries, this four IP are found
Address base differs greatly, coverage rate maximum difference nearly 30%, and when the rank of comparison is lower, the coverage rate in IP address library with
And coincidence factor can all decline, the confidence level of data also declines therewith.In addition, in the IP address library of four domestic mainstreams, no matter
It is from the point of view of coverage rate or coincidence factor, the quality of data of D address bases will be less than other three IP address libraries.Therefore it can not find
Before other three IP address libraries are the evidences mutually used for reference, comprehensive four IP address libraries can in the performance of coverage rate and coincidence factor
To obtain, D address bases are that confidence level is minimum, the confidence level highest of A address bases.
