博客评论数据集

Data Set Information: 这些数据来源于博客文章。对博客帖子的原始HTML文档进行了爬网和处理。与数据相关联的预测任务是预测未来24小时内的评论数量。整齐为了模拟这种情况，我们选择一个基准时间（过去）并选择在所选基准日期/时间之前最多72小时发布的博客文章。然后，我们根据basetime提供的信息计算所选博客文章的所有特征，因此每个实例对应一篇博客文章。目标是博客文章在未来24小时内相对于基准时间收到的评论数。 In the train data, the basetimes were in the years 2010 and 2011. In the test data the basetimes were in February and March 2012. This simulates the real-world situtation in which training data from the past is available to predict events in the future. The train data was generated from different basetimes that may temporally overlap. Therefore, if you simply split the train into disjoint partitions, the underlying time intervals may overlap. Therefore, the you should use the provided, temporally disjoint train and test splits in order to ensure that theevaluation is fair. Attribute Information: 1...50: Average, standard deviation, min, max and median of the Attributes 51...60 for the source of the current blog post With source we mean the blog on which the post appeared. For example, myblog.blog.org would be the source of the post myblog.blog.org/post_2010_09_10 51: Total number of comments before basetime 52: Number of comments in the last 24 hours before the basetime 53: Let T1 denote the datetime 48 hours before basetime, Let T2 denote the datetime 24 hours before basetime. This attribute is the number of comments in the time period between T1 and T2 54: Number of comments in the first 24 hours after the publication of the blog post, but before basetime 55: The difference of Attribute 52 and Attribute 53 56...60: The same features as the attributes 51...55, but features 56...60 refer to the number of links (trackbacks), while features 51...55 refer to the number of comments. 61: The length of time between the publication of the blog post and basetime 62: The length of the blog post 63...262: The 200 bag of words features for 200 frequent words of the text of the blog post 263...269: binary indicator features (0 or 1) for the weekday (Monday...Sunday) of the basetime 270...276: binary indicator features (0 or 1) for the weekday (Monday...Sunday) of the date of publication of the blog post 277: Number of parent pages: we consider a blog post P as a parent of blog post B, if B is a reply (trackback) to blog post P. 278...280: Minimum, maximum, average number of comments that the parents received 281: The target: the number of comments in the next 24 hours (relative to basetime) Relevant Papers: Buza, K.
