After some digging around - I visited the SVN repo where the opencalais for stanbol is implemented - I think I found the issue. The current Stanbol implementation of the enhancer for opencalais is configured for the old URL ( http://api.opencalais.com/enlighten/rest/ ) whereas it should be configured to the new URL ( https://api.thomsonreuters.com/permid/calais ). As I am not a member of the Stanbol committers forum I cannot make the changes but I suppose you can request this small change from the Stanbol forum.
Alternatively you can try to configure the new Calais URL by using the 'Configuration' tab of the Apache Felix Web Console of your Stanbol instance.
Please let me know how you manage this.
Hi Eyal, thank you for your reply. I was testing within the browser, http://localhost:8080/enhancer/chain/all-active , below:
Enhancement Chain: all-active all 9 engines available < List of Enhancement Chains >
Paste some text below and submit the form to let the Enhancement Chain all-active enhance it:
The Stanbol enhancer can detect famous cities such as Paris and people such as Bob Marley
Execution of Chain R2_chain failed in 2.00sec.
The OpenCalais engine is configured and active, as shown in the screenshots
Is there anything else I need to set/change in order for it to function? Thanks.
Thank you Eyal for taking the time to dig into this.. "Unfortunately" Stanbol was already configured with the new URL ( https://api.thomsonreuters.com/permid/calais ) when I tested it, please see http://semantic.r-2apps.com/Stanbol.Calais_1.png.
OK then... it seems I'll have to access OpenCalais outside Stanbol. Thanks again. Adrian
