This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



Tagaroo gives you an integration between your WordPress blog and the Calais web service. Tagaroo fetches semantic data (people, places, events, etc.) relevant to your blog post that you can use as tags. Tagaroo will also use these tags to search Flickr for appropriately licensed images for you to use in your blog posts. Introduced in version 1.5 are Company PermID tags. These tags are denoted by an orange stripe, or can be filtered via the dropdown menu in the tag suggestion box. Company tags found within the content of a post will automatically link to their PermID page which includes company information.


When writing blog posts, click the “Suggest Tags” link at any time to fetch appropriate tags and photos for the post.

With 1.4 we have added the functionality where you can select a paragraph or part of the post and click the ‘Suggest Tags’ to fetch fetch appropriate tags and photos for only selected text.

You can enter your own tags, or use tags suggested by Tagaroo. You can drag tags from the suggested tags list to the Post Tags area, or click on them to add them.

You can also drag tags up to the Tagaroo images list and Tagaroo will search Flickr for photos for that tag. You can sort the returned photos by interestingness, date take and date posted.

Clicking on a photo will show you a larger preview of the photo, and you can choose the size of the photo you want to add to your post.

Tagaroo 1.3 will now identify 50 event types (up from 33 in the last version). We have made minor changes to the suggested tag names for some events.

New names are

  • More descriptive/real world, for example ‘Business Relationship’ instead of ‘Alliance’
  • Unify some of the old ones, for example now we will have ‘M&A’ for ‘Acquisition’ and ‘Merger’ or ‘Judicial Event’ for ‘Indictment’, ‘Trial’ and ‘Arrest’.

Old posts tagged with previous names will not be affected at all with this change. However, if you would like to use new naming for your old posts you just need to edit the post and save it with new names.
