With reference to figure 1, show the process flow diagram of method embodiment one of a kind of definite file bag resource identification information of the embodiment of the invention, can may further comprise the steps:
Preferably, file that described literature kit comprised and/or file can for, file and/or file that the root directory layer of described literature kit (being ground floor catalogue in the literature kit) is comprised.Because generally the content information that the name information of the file or folder of the root directory layer of literature kit more can the representation file bag so can improve the efficient that file bag resource identification information is determined.In this case, only need be at the included file of literature kit root directory layer and/or the attribute information of file, whether satisfy pre-conditioned judgement, can determine the name information that satisfies some file or folders pre-conditioned, described literature kit root directory layer is the resource identification information of described literature kit.
In practice, each literature kit all has a corresponding file tabulation, is used for the information of log file bag All Files and file.The form that listed files shows in dissimilar literature kit is different, every kind of all corresponding agreement separately of compression type, so agreement according to each compression type, grasp the file header of literature kit by web crawlers (spider) or other instrument, file header is analyzed, just can be obtained corresponding listed files.
Particularly, the acquisition process of described listed files is: the spider program is creeped automatically according to the link between the page in the internet, in case find the literature kit (as the compressed file bag) of preset kind, then grasps; After the extracting, the file header of current file bag is analyzed, promptly obtained corresponding listed files.
Generally include in the listed files: size information, file type, modification time and annotation information after name information (filename), directory information (being embodied in the filename usually), document size information, the compression or the like.For example, the file header information of certain zip formatted file bag is as shown in the table:
| Compression method (compression algorithm) | 2bytes |
| Crc-32 (cyclic redundancy check (CRC)) | 4bytes |
| Compressed size (compression back size) | 4bytes |
| Uncompressed size (original size) | 4bytes |
| Filename length (filename length) | 2bytes |
| Filename (file name) | variable size |
Wherein, filename is exactly the name information of file, and uncompressed size is exactly the original size information of uncompressed.In practice, after the information extracting of spider with file header, can also extract filename, uncompressed size information deposits in the database.
In embodiments of the present invention, described attribute information can be document size information, in this case, in the described step 102 pre-conditioned can for:
The size of condition S1, file or folder is maximum in the described literature kit.
Perhaps,
The size of condition S2, file or folder accounts for the magnitude proportion of described literature kit more than or equal to a threshold value.
With reference to figure 2, show and use described condition S1 to determine the process flow diagram of the method embodiment two of file bag resource identification information as of the present invention another, can may further comprise the steps:
In the present embodiment, document size information based on the listed files reflection, the file of the root directory layer of statistics file bag and/or the size of file, the size of described file or folder is compared, if corresponding size is maximum file or folder, then represent the content of this document or file is occupied an leading position in this document bag, therefore, can determine the name information of the file or folder that this is maximum, be the resource identification information of this document bag.
For example, the listed files information of certain literature kit comprises: the rule political affairs Shinjin-O first collection .rmvb, the rule political affairs Shinjin-O second collection .rmvb, TV play are shone performer's picture Xin Wan .jpg of army, TV play according to performer's picture lily.jpg, player .exe; Wherein, the file of root directory layer and file are: rule political affairs Shinjin-O, TV play are shone, player .exe, the size information of supposing described each file and file is respectively: rule political affairs Shinjin-O-3GB, TV play photograph-2MB, player-23MB, because " rule political affairs Shinjin-O " corresponding file size is maximum, be the resource identification information of described literature kit so can choose " rule political affairs Shinjin-O " in the file of all root directory layers.
With reference to figure 3, show and use described condition S2 to determine the process flow diagram of the method embodiment three of file bag resource identification information as of the present invention another, can may further comprise the steps:
Step 301, each file that obtains a literature kit root directory layer and/or the size information of file;
Step 302, if the size information of certain file or folder in described literature kit root directory layer in the big or small sum in All Files and the literature kit, proportion is more than or equal to a threshold value, and the name information of then extracting this document or file is the resource identification information of described literature kit.
In the present embodiment, document size information based on described listed files reflection, the file of the root directory layer of statistics file bag and/or the size of file, if accounting for whole literature kit All Files size, the size of certain file or folder surpasses certain proportion, then represent this document or file are occupied an leading position in literature kit, therefore, just with the name information of this document or file, be defined as the resource identification information of this document bag.
For example, the listed files information of certain literature kit comprises: the rule political affairs Shinjin-O first collection .rmvb, the rule political affairs Shinjin-O second collection .rmvb, TV play are shone performer's picture Xin Wan .jpg of army, TV play according to performer's picture lily.jpg, player .exe; Wherein, the file of root directory layer is: rule political affairs Shinjin-O, TV play photograph, and, the file of root directory layer is: player .exe, in this case, then need from: rule political affairs Shinjin-O, TV play according to and player .exe determine resource identification information, be specifically as follows:
A. obtain described each file or file size w (i), calculate a total big or small total, for example, can pass through following formulate:
Total＝w(1)+w(2)+w(3)
B. the big or small w (i) that calculates each file or folder respectively accounts for the ratio f (i) of described total big or small total, for example, can pass through following formulate:
f(i)＝w(i)/total
If above-mentioned f (i) is greater than certain preset ratio, as 80%, then with the name information of this document or file as resource identification information.Suppose to go up in the example, the ratio of " rule political affairs Shinjin-O " reach 80% or more than, then will " rule political affairs Shinjin-O " as resource identification information of this document bag.
Need to prove, in embodiments of the present invention, because the file of corresponding different-format, compress mode also has difference, thereby causes the file size after each compression, and existence and itself size are not the problems that reduces in proportion, thereby in this case, if described literature kit is the compressed file bag, the document size information in the foregoing description is preferably the size information before the file or folder compression, but not the size information after the compression.In addition, have under a plurality of situations at file bag resource identification information, can choose a resource identification information wantonly as literature kit, perhaps, adopt Else Rule to choose a resource information as literature kit, perhaps, all be feasible as the resource identification information of literature kit directly with described a plurality of name informations, the present invention does not limit this.
In embodiments of the present invention, described attribute information can also be name information, in this case, in the described step 102 pre-conditioned can for:
The name information of condition S3, file or folder does not match with the invalid key that presets;
And/or,
The name information of condition S4, file or folder is complementary with the effective key word that presets.
In practice, the name information of some literature kit also can reflect the main contents of file bag resource truly, effectively, thereby preferred, and described candidate target can also comprise described literature kit itself, in this case, described pre-conditioned can for:
The name information of condition S3 ', described literature kit, or the name information of file or folder does not match with the invalid key that presets in the described literature kit;
