Public tags added to resources in Trove, 2008 to 2024

<p>This dataset contains details of 2,495,958 unique public tags added to 10,403,650 resources in <a href="https://trove.nla.gov.au/">Trove</a> between August 2008 and June 2024. I harvested the data using the Trove API and saved it as a CSV file with the following columns:</p> <ul> <li>`tag` &ndash; lower-cased text tag</li> <li>`date` &ndash; date the tag was added</li> <li>`zone` &ndash; API zone containing the tagged resource</li> <li>`record_id` &ndash; the identifier of the tagged resource</li> </ul> <p>I've documented the method used to harvest the tags in <a href="https://github.com/GLAM-Workbench/trove-lists/blob/master/harvest-tags.ipynb">this notebook</a>.</p> <p>Using the `zone` and `record_id` you can find more information about a tagged item. To create urls to the resources in Trove:</p> <ul> <li>for resources in the 'book', 'article', 'picture', 'music', 'map', and 'collection' zones add the `record_id` to `https://trove.nla.gov.au/work/`</li> <li>for resources in the 'newspaper' and 'gazette' zones add&nbsp;the `record_id` to `https://trove.nla.gov.au/article/`</li> <li>for resources in the 'list' zone add the `record_id` to `https://trove.nla.gov.au/list/`</li> </ul> <p>Notes:</p> <ul> <li>Works (such as books) in Trove can have tags attached at either work or version level. This dataset aggregates all tags at the work level, removing any duplicates.</li> <li>A single resource in Trove can appear in multiple zones &ndash; for example, a book that includes maps and illustrations might appear in the 'book', 'picture', and 'map' zones. This means that some of the tags will essentially be duplicates &ndash; harvested from different zones, but relating to the same resource. Depending on your needs, you might want to remove these duplicates.</li> <li>While most of the tags were added by Trove users, more than 500,000 tags were added by Trove itself in November 2009. I think these tags were automatically generated from related Wikipedia pages. Depending on your needs, you might want to exclude these by limiting the date range or zones.</li> <li>User content added to Trove, including tags, is available for reuse under a CC-BY-NC licence.</li> </ul> <p>See <a href="https://github.com/GLAM-Workbench/trove-lists/blob/master/analyse_tags.ipynb">this notebook</a> for some examples of how you can manipulate, analyse, and visualise the tag data.</p>
