UrlAi.com

Classifies blogs on gender, age, mood and tonality. Blogs are followed over time to give more accurate results.

TrollGuard is a free WordPress plugin that protects your blog from spam comments.

Typealyzer.com

This innovative site finds out the blog author personality, using a psychological text analysis. Check it out!

GenderAnalyzer.com

This neat web site figures out if a blog is written by a man or woman, using the uclassify web service.

AgeAnalyzer.com

Tries to guess the author age from reading a blog.

We have created a new service called UrlAi.com, the basic concept is to run blog posts through a bunch of classifiers over time. To begin with we use Gender, Age, Mood and Tonality but the system is dynamic so we can add new classifiers at any time. If you have created a classifier that would fit on urlai.com let us know!

Some ideas

We have many ideas of how we can develop this project further, for example, now we are only showing a summary pie chart, it would be nice to see posts over time. User feedback for online training and classifier improvement may be possible. Another thing we could do is to have classified posts searchable, for example, enabling users to see the mood of everyone who mentioned ‘Avatar’.

Some kudos

Just want to thank the people that has been involved in this project, Roger Karlsson for coding, Johanna Forsman for the awesome logo and Mattias Östmar for sharing his Tonality and Mood classifiers. Mattias has also contributed with many ideas around this, being the idea fountain he is

We have just released ageanalyzer.com, a site that reads a blog and guesses the age of the author!

Background

Our writing style reflects us in many ways, for example texts written in anger probably differs from words written in joy.  Reading a text intuitively gives us a clue about the author as you start forming a picture in your head.  Sometimes it’s easy to pinpoint how you got this picture and at other times harder.

We wanted to know if we could give computers the same intuition, in this particular project we are interesting in finding out if a computer can tell the age of an author - only given a text.

To do this experiment we collected 7000 blogs that had age information in the profile and split it into 6 different age groups, 13-17, 18-25, 26-35, 36-50, 51-65 and 65+. We then created a classifier on uClassify and fed it with the training data. Viola!

Expected results

After running tests on the training data (10-fold-cross-validation) it was clear that our classifier was able to find differences between the six age groups. We expect the proportion of correctly classified blogs would be around 30% compared to a baseline of 17% which would be expected if the classifier was guessing out of the blue.

We have added a poll to the site to help us see how well (or poorly) it works!

If you read this and are using uClassify for a project feel more than free to contact me with any positive or negative feedback on any aspect (classifier performance, documentation, response times or any unclarity). You may leave a comment or e-mail me at this address: contact at uclassify dot com. <– Are spambots able to read this now days?

Over and out!

“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!

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
}
}

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

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

http://www.uclassify.com/browse/uClassify/GenderAnalyzer_v5/ClassifyUrl?readKey=YourReadKeyHere&url=http%3A%2F%2Fwww.rogerkarlsson.com&removeHtml=1

The new API is documented here.

As a result this site is much faster to browse, the biggest contrast can be seen when browsing the classifiers.

Keep the classifications going!!

Happy times!
