DupPRDataset/pullreq_info

English description of the fields in pullreq.sql：

• repo_slug: The slug of the project (user_name/repository_name), which can compose the homepage URL of the project with a heading string https://github.com/.
• pr_num: The tracking number of the pull-request.
• pr_info: A Json object obtained via GitHub API, which contains the basic information of pull-request. The commonly used attributes can be directly parsed from this object, e.g., one can get the pull-request title by calling json_obj["title"]. More information demanded in specific context can be requested from the hyperlink value of the corresponding field, e.g., one can get the review comments of a pull-request from json["review_comments_url"].

文件pullreq.sql中字段的中文描述：

• repo_slug: pull-request所属项目的标识（用户名/仓库名）。
• pr_num: pull-request在项目追踪系统中的编号。
• pr_info: 这是使用GitHub API采集获得的json对象，包含了pull-request的基本信息。一些常用的信息可以直接从该对象解析，例如ppull-request 的标题可以通过json_obj["title"]获取。其它的信息需求可以通过字段所对应的链接进行二次采集，例如可以通过json["review_comments_url"]获取pull request的审查评论。
