In step S11, obtain Web Community's data, and generate corresponding index data, this index data comprises text index data, authority index data and user index data.
In the present embodiment, Web Community's data of obtaining comprise text data, permissions data and user data.Wherein, permissions data is used for describing the authority that each user has the text data that obtains, such as the user who describes in the community text data 1 that obtains is had the authority of checking, the user outside the community does not then have the information of the authority of checking etc. to text data 1.Wherein, user data is used for describing the user owner of text data, and the user owner of text data and the relation between other users in the community, such as, supposing that user A has delivered text data 4, user B has delivered text data 5, and user A and user B are good friend's relation in the X of Web Community, then text data is user A for the user owner who describes text data 4, and the user owner of text data 5 is user B, and user B and user A are good friend's relation in the X of Web Community.
In order to be illustrated more clearly in the relation between text data, permissions data and the user data, the below uses form to describe, and is specifically as shown in table 1:
Table 1:
Content as shown in table 1, that user 1 and user 2 can check text 1, and user 3 cannot check the content of text 1; In like manner, user 1, user 2, user 3 have the authority of checking text 2; Text 3 only has user 3 to have the authority of checking, user 1 and user 2 do not have the authority of checking text 3.
Wherein, obtain Web Community's data, and the step that generates corresponding index data is specially:
A, obtain Web Community's data.In the present embodiment, obtain all Web Community's data from the network data provider of community, comprise and obtain text data, permissions data and user data.
B, resolve this Web Community's data, and generate the text index data according to text data, generate the authority index data according to permissions data, generate the user index data according to user data.In the present embodiment, resolve text data, permissions data and user data, generate the text index data, authority index data and the user index data that meet indexed format, wherein, the data that meet indexed format are scale-of-two input data.
Wherein, the step according to text data generation text index data is specially:
1, the text data that obtains being carried out re-scheduling processes.In the present embodiment, owing to having a lot of text datas to repeat to reprint in community's network data, may there be a plurality of identical text datas in the text data that therefore obtains.For conserve storage, need to carry out to the text data that obtains re-scheduling and process: if there are a plurality of identical text datas, then only keep one of them text data.Wherein, the step of the text data that generates being carried out the re-scheduling processing is specially: adopt fingerprint algorithm to calculate the md5 value of each text data, and the text data that will have identical md5 value is judged to be identical text data, and only keeps any text data corresponding to different md5 values.In the present embodiment, the md5 value of text index data is equivalent to the fingerprint of text data, is used for distinguishing different text datas.
2, generate the text index data according to the text data after the re-scheduling processing.In the present embodiment, the text data that obtains is carried out after re-scheduling processes, each text data that remains is different, thereby according to the different different text index data of text data generation, has saved storage space.
