BL Flickr image dataset: User Submitted Tags (til March 2016)

These illustrations, diagrams and decorations were extracted from 65,000 volumes of digitised works.The dataset is a table of the descriptive and other tags added by contributors to the images in order to better describe them, and contain all the user-submitted ones to date (March 2016).The data table (in TSV format) has the following columns:flickrid - The id of the image.enteredtext - The text typed in by a contributor.from - the epoch time (in seconds) since the last data harvest before the 'to' harvest.to - the epoch time of the metadata harvest that the change was detected intagid - The tag identifier supplied by Flickrauthor - The user's account who added the tagtag - The simplified version of the text, used in flickr's URLs and so on.mode - either 'add' or 'del', showing that a tag has either been added since last harvest, or that it has been removed since then.
