Microblog and Web corpus

The festival galleries dataset

by Eric SanJuan

This data set allows to experiment microblog search and stream summarization.

Microblog collection

The document collection is provided to registered participants by ANR GAFES project. It consists in a pool of more than 50M unique micro-blogs from different sources with their meta-information as well as ground truth for the evaluation.

The microblog collection contains a very large pool of public posts on Twitter using the keyword festival since June 2015. These micro-blogs are collected using private archive services based on streaming API. The average of unique microblog posts (i.e. without re-twitts) between June and September is 2, 616, 008 per month. The total number of collected micro-blog posts after one year (from May 2015 to May 2016) is 50, 490, 815 (24, 684, 975 without re-posts). These micro-blog posts are available online on a relational database with associated fields.

Because of privacy issues, they cannot be publicly released but can be analyzed inside the organization that purchased these archives and among collaborators under privacy agreement. The CM2 lab provides this opportunity to share this data among academic participants. These archives can be indexed, analyzed and general results acquired from them can be published without restriction.

Linked web pages

66% of the collected micro-blog posts contain Twittert.co compressed URLs. Sometimes these URLs refer to other online services like adf.ly, cur.lv, dlvr.it, ow.ly that hide the real URL. We used the spider mode of the GNU wget tool to get the real URL, this process required multiple DNS requests.

The number of unique uncompressed urls collected in one year is 11,580,788 from 641,042 distinct domains.
