Learn About the Open Source Alternative to ClearForest

January 22, 2014

Did you know that there was an open source version of ClearForest called Calais? Neither did we, until we read about it in the article posted on OpenCalais called, “Calais: Connect. Everything.” Along with a short instructional video, is a text explanation about how the software works. OpenCalais Web Service automatically creates rich semantic metadata using natural language processing, machine learning, and other methods to analyze for submitted content. A list of tags are generated and returned to the user for review and then the user can paste them onto other documents.

The metadata can be used in a variety of ways for improvement:

“The metadata gives you the ability to build maps (or graphs or networks) linking documents to people to companies to places to products to events to geographies to… whatever. You can use those maps to improve site navigation, provide contextual syndication, tag and organize your content, create structured folksonomies, filter and de-duplicate news feeds, or analyze content to see if it contains what you care about.”

The OpenCalais Web Service relies on a dedicated community to keep making progress and pushing the application forward. Calais takes the same approach as other open source projects, except this one is powered by Thomson Reuters.

Except it’s not open source, the code is not available. It’s a web service free for commercial and non-commercial use. If you want open source entity extraction the best place to start is Stanford NLP which is properly open source software.

Hi there just wanted to give you a quick heads up.
The text in your post seem to be running off the screen in Ie.

I’m not sure if this is a format issue or something to do
with browser compatibility but I thought I’d post to let you know.
The design and style look great though! Hope you get
the problem resolved soon. Thanks
