Tagging content: copyright image, used under license from

Tags on this site are non-hierarchical terms assigned to categorise and describe the content of articles. Specifically, tags are defined here as 'buzz' keywords or as the names of organisations, projects, and authors of interest.

Our tagging system is designed to facilitate discovery of related content across more than 1600 articles and to help monitor trends in discussion since Ariadne started publication in 1996.  

Specifically, this system looks for designated terms of interest, automatically tagging articles containing these terms (or close variants and synonyms).

In addition to our standard list of target terms, our system allows for some manual tagging of articles by editors.

Yes, we are continuously expanding and refining the automated tagging system used on this site.  

Our tagging system readily accommodates the listing of new target terms, management of synonyms, and specification of canonical terms.

If you are interested in a term not currently in our list of all tags tracked on this website, let us know.

By using the option in our feedback form to suggest additional keywords you would like us to consider monitoring, you can help us tune our automated tagging system to the evolving interests of readers.

Our site provides several overviews of tags:

  • keywords overview: tags related to key topics tracked by this site
  • organisations overview: tags related to universities, companies, groups etc. discussed in Ariadne
  • projects overview: tags related to projects tracked by this site
  • authors overview: tags specifying names of authors and editors contributing to articles
  • issues overview: tags designating issue numbers

As illustrated below, each overview page includes descriptions, statistics, and links to charts related to tags.  Our next FAQs explain features of these overviews in more detail.

Among the statistics provided by our site is the number of items related to a tag.  

As illustrated below, near the top of each overview page you can see the total of items tagged.  

Even if the overview runs over several pages, this total accounts for all items in the overview.

Whenever you use  'Filter by ...' options in overview pages, totals of items change accordingly.

Each total number of tags displayed takes into account filters that have been applied to an overview.

When following any tag link, you will be presented with an overview of all articles related to your selected tag.

As illustrated below (with example of 'google' tag overview page), in addtion to a complete list of articles related to a tag each overview page also includes:

  • brief descriptions of tags
  • summaries of statistics
  • links to charts

As explained in 'Questions about filtering', tag overview pages include several 'Filter by ...' options to help you narrow the focus on specific topics of interest.

Depending upon the content of each article, a range of tags are displayed in the right column of each article page.  

You can use these tags to find all related content:

  • Issue number tag links to overview of all content within a specified issue
  • Article type tags link to overviews of all articles of a specified type
  • Author tags link to overviews of all content by a specified author
  • Organisation tags link to overviews of all content mentioning a specified organisation
  • Project tags link to overviews of all content referring to a specified project
  • Buzz tags links to overviews of all content related to a specified term

As explained in 'Questions about filtering', when following links to tag overviews you will find several options to filter results and narrow your focus to specific items of interest.

This site provides options for exporting content and metadata in structured formats, which we hope that you will find convenient.

You can use 'CSV' or 'XML' or 'RSS' links (provided near the bottom of overview pages) to download sets of tag descriptions and related metadata.  

As illustrated below, this site offers a range of export options from tag overview pages:

  • our default feeds in CSV, XML, and RSS formats provide convenient ways to access 'selected' sets of content and data (typically limited to 40 items in a set)
  • these default feeds can be filtered (see FAQs explaining filtering), so you can narrow focus to smaller sub-sets of content and data specifically related to your interests
  • in some cases we also provide options for 'complete, paged' feeds, designed for exporting larger content and data sets
  • these optional 'complete, paged' feeds can help you access large sets of content and data efficiently (see our FAQ explanation of feed paging arrangements)

A couple reminders:

In some cases, where datasets are large, we provide options for 'complete, paged' CSV, XML, and RSS feeds designed for efficiency of size and speed in downloads.

As illustrated below, paged feeds start with the query-string parameter page=0.  Such feeds can then be incremented by adjustments of the query string, so that page=1 fetches the next set of data, page=2 fetches the next, etc.

Note that if you provide an invalid number in the query string when paging, and no such page exists in the feed, then the paged feed returns to the start of the feed (as if you had requested page=0).

With this paging arrangement, you can cycle through feeds of content and data in relatively small chunks, optimised for efficiency.
