Tagmatic is a service for automatically tagging your content.
It uses sophisticated machine learning techniques to learn how you tag your content on-the-fly and then will tag new content automatically.
Tagmatic uses your own tag dictionaries. Whether you tag with simple text terms, identifiers, taxonomies, or linked data, Tagmatic will tag with those.
There is no data mapping exercise needed, just send your content & tags to Tagmatic and it gets to work. Tagmatic quickly learns new tags too.
It is incredibly easy to integrate into your CMS or editorial workflows via two simple web service interfaces.
If you are looking for an automated tagging solution, then look no further.
If you are developing your own automated tagging solution, then pause, give Tagmatic a try - and be up and running quickly.
Update @ 2020:
Tagmatic has been renamed as "Text AI Services: Text Classification" as part of our "Data Language AI" product suite.
