Connection pool bug fix

Some users have experienced

“Timeout expired.  The timeout period elapsed prior to obtaining a connection from the pool.  This may have occurred because all pooled connections were in use and max pool size was reached.”

This happened because some database connections persisted longer than expected and as a result the connection pool was drained. This became obvious with the release of the URL API. The bug should have been fixed now.

I’m also really happy to see that we are getting a lot new users since the introduction of the URL API!

URL classification API with JSON responses

Many people have contacted me asking for JSON support. I’ve not used it myself earlier but it seems like a widely used format, so I decided to implement support in our new URL API.

Just add the the argument output=json on the end of a classification URL request.

Please let me know if there is anything that looks weird in the JSON API or if something should be redesigned.

Beer…. is the word more used by men or women?

If you click will be asked to save a file due to the MIME content type application/json, however this is how the response looks:

“version” : “1.00”,
“success” : true,
“statusCode” : 2000,
“errorMessage” : “”,
“cls1” :
“female” : 0.15623,
“male” : 0.84377

New API for classification

We are really happy to announce that we just have released an URL API to make it easier to access classifiers. This means that users can classify via an URL, for example finding out the language of the text snippet from Wiki:

“En apprentissage automatique, le terme de classifieur linéaire représente une famille d’algorithmes de classement statistique.”’algorithmes%20de%20classement%20statistique.

You can also classify URLs directly. For example this call confirms that Rogers blog is written by a male:

The new API is documented here.

Using published classifiers

We’ve just implemented so that everyone with a uClassify account (free) can access public classifiers.

Once a classifier is published everyone can use it via the GUI or the web API and in return authors get a link to their website from everyone who use their classifiers. This should hopefully inspire more people to share their cool classifiers!

As an example of a published classifier check out the mood classifier by Here is the list of all published classifiers.


As we suspected, most users who sign up think it’s to high threshold to get started as it requires some programming to create and train classifiers. Therefore we have decided to add more GUI features that allows users to do all the API calls without any programming! Once classifiers are set up developers can start building their web application around their classifiers via the API.


All GUI driven API calls will display the generated the XML so that users can easily see whats going on and copy the XML directly into the code (much like PhpMyAdmin does with SQL queries).

We expect this to take a couple of weeks.
