Hi Thomas,

yes, that's all.  Note that the current implementation
of the CAS doesn't do any garbage collection.  Removing
the FS from the indexes only means that it is no longer
accessible via indexes (and therefore not at all, if it's
not accessible as the feature value of some other FS).
Hope that makes sense.

RE: Asynchronous UIMA (workflow) ?

[Pascal Coupet <pa...@temis.com>]

Hi Thomas,

 

I think a way to do it is to split this process across 2 workflows. The first consumer will get the CAS, eventually store it in XML somewhere (file, database ...). A small application will manage the interaction with the user (sending mail, reminders ...), watch a return address mailbox, update the XCAS and make it available. The source of the second workflow will watch for available updated XCAS and continue from there. You can in theory make the consumer of the first workflow to send the mail and the source of the second watch for incoming emails but it will be more difficult I think to manage properly the interaction with users (reminder to responds, statistics, routing configuration ...). 

 

Just some thoughts,  

 

Pascal

Subject: Asynchronous UIMA (workflow) ?

 


Hi all -

I'm thinking about whether or not it would be possible to add an asynchronous step in a UIMA pipeline ? For example having an analysis engine that would ask for a user input or a user review of a CAS, or something like that. Well my point is that at some point in the pipeline, I would like a user to review the state of the CAS, maybe add some more information, delete some others, and so on; and then the rest of the pipeline would continue upon user validation. (by "user" here I don't mean someone that sits in front of a computer and watch the UIMA processing taking place, but maybe someone receiving an email saying "hey, you should have a look and validate that").

I know this a generic workflow question, but I was just wondering if some other people had the same question/requirements with a UIMA integration, and if you had some ideas on how it could be adressed/solved.

Best,
Thomas
