Reuters have launched OpenCalais a service that will encourage the development and growth of the Semantic Web.
Aimed at developers and information publishers, OpenCalais is web service that can extract meaningful terms from well written text. When fed a newspaper article or business report the service will identify the people, places, monetary values, companies and institutions mentioned and will organize references to those terms to ease further research. In well structured business text Calais can also interpret and classify facts; recognizing and reporting joint ventures, mergers, acquisitions, earnings announcements etc.
End users will not interact with Calais directly, but will access the service through third party applications, plugins and utilities. Development of these will be encouraged through programming bounties, the first offers $5000 for the development of a Wordpress plugin.
In the long term, initiatives like OpenCalais will help us work more effectively with the increasing flow of information that surrounds us. These are distinct strategic and personal benefits to be gained from generating, and being able to work with, structured information instead of being swamped by raw data.
It was a welcome relief at Monday’s Vancouver Facebook Developer Garage to see so many useful, well-designed and well engineered applications. Of particular note is Active State’s Eat-O-Rama.

A restaurant discovery and rating application written in Python with a mySQL database, the application’s smooth and responsive interface shows the quality that can be expected from a dedicated, experienced team devoting months of focussed effort. Equally impressive is the commitment to a development philosophy that makes comparison testing an integral part of the design process.
Some notable quotes from the presentation are:
“People like to interact where no response is necessary, but a response is possible.”
“The most important thing is to deliver real value to the person using the application. Then impart additional value to their friends.”
Details of the other applications presented are on Miss 604’s blog, which amazingly was produced live during the event.
issuu™ is a beautiful way to publish documents on-line. Created to give a magazine look and feel to online documents issuu has a breathtaking interface combined with a simple publication process.
issuu documents are hosted free of charge and can be embedded in any web page or blog, or shared on social networks.
The embed gives a thumbnailed view of the entire document from which the publication can be opened for more comfortable reading. This in turn allows you to open a full screen view that is an absolute pleasure to use. In full screen the interface fades into the background leaving the viewer to enjoy the publication design with no distractions.
This is an ideal solution for presenting work where the fidelity of the graphical composition and typography is important.
It has limitations:
- Text is not exposed to search engines and cannot be copied to the clipboard.
- The hosted publications can be embedded by anyone, on any site; which means you must be very conscious of copyright issues.
- Comments can only be made on the publication as a whole, which can be a little coarse-grained for larger documents.
Other than that, issuu is an excellent technology that will be as useful in the publication of brochures, books and portfolios as it is in magazine publication and photography.
