Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0044] The implementation process of constructing PCU associated data from elements scattered on various pages and their logical relationships on Sina Weibo is as follows: figure 1 As shown, it can be divided into the following three processes:

[0045] (1) Acquisition of data access rights, including 5 steps.

[0046] Step 1: Start the IE browser through selenium, automatically enter the Sina Weibo login homepage http: / / www.weibo.com / login.php, locate the HTML tag and enter the account and password ;

[0047] Step 2: Use selenium to automatically fill in the registered user name and password according to the label in step 1, such as filling in the account "robbersunsohu.com" and password "897fgCKdf";

[0048] Step 3: According to whether the login page contains the HTML tag , determine whether it is necessary to enter the verification code; ...

Abstract

The invention discloses a method for acquiring PCU association data from microblogs, and aims to overcome the technical defect of incapability of acquiring associated microblog posts, comments and posters in the prior art. The method comprises the following steps: (1) gaining of a data access permission: automatically filling identity authentication information by analyzing login page HTML (Hypertext Markup Language) tags to gain the data access permission; (2) downloading of PCU association data pages: automatically and sequentially downloading pages containing PCU association data under the guidance of the logical relation of the PCU data according to the HTML structures and tag semantics of microblog pages; and (3) structured parsing and construction of the PCU association data: fusing post relations, user-friend relations and user-post sub-relations to construct a heterogeneous network, namely, a PCU association data network. Through adoption of the method, the PCU association data in Sina microblogs can be acquired automatically; the structured association data network is constructed; and a good data set is provided for subsequent social network mining.

Description

technical field [0001] The invention belongs to computer social network data acquisition technology, in particular to a method for automatically acquiring PCU related data of a specific topic in microblogs. Background technique [0002] The Internet and Web 2.0 promote the rapid development of social networks. Social networks have a large number of users and rapid data generation. The increasing accumulation of data and its complex correlation structure make it more and more difficult to obtain and understand information. [0003] Sina Weibo, the most influential social networking site in China, contains a large amount of potentially valuable information. An important aspect of studying this information is to analyze posts on specific topics, post comments, and posting users in Sina Weibo. These data are scattered in different pages, causing people to be unable to quickly and accurately find or understand these useful information from a large number of pages. [0004] There...
