Real World Example

SuperTagging came about when The Washington Times was looking for a cheap alternative method of tagging its contents. The previous method was the process of sending the content to a similar, but paid service, and that service would return keywords and the content in its marked up state. The content then was saved into our story body field with the links in place. These links went to a section of our site we then called “Themes”.

The first thing we wanted to get rid of was the monthly fee we had to paid for the service, we ended up finding OpenCalais, which gave us a free way to tag our content and also be able to easily markup our content with the links as before.

We now have a similar section on our site called Topics which is powered by SuperTagging, and most of our stories have the links to this section as before.

This section of the documentation, we will go through all the pieces of SuperTagging we use here at The Washington Times.

Our current SuperTagging settings

This first group of settings are the general settings.



We have USE_QUEUE set to True. Together with AUTO_PROCESS set to True, the objects are saved into the SuperTagQueue model for later processing. We run the management command provided by SuperTagging every 5 minutes.

This next group is what we call the processing settings for SuperTagging.





We process pretty much all OpenCalais gives us, that includes the Events/Facts (relations) and Topics, which are just tags but with no meta data.

We try to convert Calais ID’s to tag names (SUPERTAGGING_RESOLVE_PROPERTY_KEYS = True)

We tag all objects every time they are saved (SUPERTAGGING_ONLY_NON_TAGGED_OBJECTS = False). This is so we can efficiently markup up the content without worry of data being stale.

We only accept tags that have at least 200 relevance

We use Freebase to disambiguate the tag names.

Next group is the markup settings

SUPERTAGGING_MARKUP_EXCLUDES = ['his', 'her', 'he', 'she', 'him',]


We markup all the objects that get processed by OpenCalais, below is an example of content after it has been marked up.

<p><a href="/topics/charles-b-rangel/">Mr. Rangel</a>, the longtime top Democrat on the House
<a href="/topics/ways-and-means-committee/">Ways and Means Committee</a> who stepped down under
pressure in March, has been under investigation by the panel for two years. At issue is a
plethora of subjects, including <a href="/topics/charles-b-rangel/">Mr. Rangel</a>'s ownership
of several rent-controlled apartments in New York; his failure to report $75,000 in earnings
on tax returns; and use of his official position to raise money for the
<a href="/topics/charles-b-rangel-center/">Charles B. Rangel Center</a> for 
<a href="/topics/public-service/">Public Service</a> at
<a href="/topics/city-college-of-new-york/">City College of New York</a>.</p>

We exclude some markup values OpenCalais returns. OpenCalais returns exactly where, in the content sent over, the reference to the tags is. This will not just be the exact tag name but also references to the tag such as his, her, she. We found that there was just too many links in the content and needed a way to limit it. So combinations of SUPERTAGGING_MIN_RELEVANCE setting and SUPERTAGGING_MARKUP_EXCLUDES provided just that.

One of the things we did not like from the old tagging service, was that the links were added to the content directly. With SuperTagging the content field of your instance is never changed when your using the markup feature. Instead, another attribute is added to your instance during processing. SUPERTAGGING_MARKUP_FIELD_SUFFIX tells what the prefix for that field will be. For example, if we wanted to markup a field named ‘content’, after SuperTagging is done processing, another attribute will be available in that model called ‘tagged_content’. This attribute will contain the content in a marked up state. This way, if we ever decided to change the way we markup our data, or change the location of where the links in the content go, we don’t need to change the instance directly.

Vist the Markup page for more information

This next set of settings we use is to exclude the types (entities) and relation types (events/facts)



The ones that are commented out are the ones we do want. So so make sense of these to lists we only want the following:

  • Tag Types (Entities)
    • Company
    • Country
    • Holiday
    • Organization
    • Person
    • RadioProgram
    • SportsEvent
    • SportsGame
    • SportsLeague
    • TVShow
  • Relation Types (Events/Facts)
    • Acquisition
    • Arrest
    • Bankruptcy
    • BusinessRelation
    • CompanyAffiliates
    • CompanyEmployeesNumber
    • CompanyFounded
    • CompanyTicker
    • Conviction
    • EmploymentRelation
    • FamilyRelation
    • PersonAttributes
    • PersonCareer
    • PersonEducation
    • PoliticalRelationship
    • Quotation

This last section is the models we tag.

            {'name': 'body',
            {'name': 'caption'},)


This we very basic, since we only tag one field for both our stories and images. One thing that will change in the future for The Washington Times, will be that we will only tag stories with particular set of origins. For example, we currently have the following origins for our stories:

    (0, 'Unknown'),
    (1, 'Admin'),
    (2, 'SaxoTech Editorial'),
    (3, 'SaxoTech Online'),
    (4, 'AP News'),
    (5, 'Bernini'),
    (6, 'AP NetNews'),

Some of these origins are not used anymore, and we will want to limit which ones we do tag, so eventually the SUPERTAGGING_MODULES will look like this:

            {'name': 'body',
         'match_kwargs': {'origin__in': [1,2,3,5]}
            {'name': 'caption'},)

If this was our current setup, we would not tag stories that had an origin of (0) Unknown, (4) AP News or (6) AP NetNews.

Running the process

Last thing is to run the cron job every 5 minutes to process the Queued objects.
