Alfresco Auto Tagging

jboss — Mon, 25 Jul 2011 15:28:47 GMT

I was wondering if Alfresco supported some kind of auto-tagging service out of the box. I know it allows for tagging, and you can use the API to add tags to uploads, but is there any kind of built in service to handle auto-tagging?If not would the OpenCalais integration I've read about on the foru

How do you imagine that "auto tagging" would work? What would your buisness rules look like.

There is already the ability to extract metadata from documents and the ability to run code when documents are added so it shouldn't be too difficult to apply some sort of tag.

I guess what I had in mind was parsing the document and tagging based on commonly used words, or possibly trying to correlate those with similar words from previous searches. But really I just needed an answer, so thanks . I'll look into other options/writing our own service.

The OpenCalais Integration Alfresco extension available in the Alfresco Forge can be used to auto tag your documents based on their content. http://forge.alfresco.com/projects/calais/ This extension also has Share UI with it http://integratedsemantics.org/2011/03/08/alfresco-opencalais-integration-share-ui/ in addition to UI for it being available in FlexSpaces. Calais / OpenCalais is not open src, its an"open api" web service that is free for low volumes.

IKS / Apache Stanbol is a completely open src / free stack (when it uses OpenNLP instead of the optional use of OpenCalais). Zaizi is working on an Alfresco integration to IKS / Apache Stanbol. Integrated Semantics will be doing additional UI for Apache Stanbol + Alfresco http://code.google.com/p/semantics4alfresco/

I added OpenCalais to my Alfresco installation, I'm still testing its semantic tagging, but what happens when I exceed these 'low volumes'? And do you have an idea of where that break might be, would it be a certain number of documents/kb per month?

Just saw this: http://www.opencalais.com/documentation/calais-web-service-api/usage-quotas
If a number of documents are submitted at the same time, is the processing rate automatically capped at 4 per second then?

You would have to check with OpenCalais support for more info on the limits. The Calais integration has been ported to Apache Stanbol, which is open source and won't have these limits http://code.google.com/p/semantics4alfresco/
