Can I do something > similar using that? The external resource mechanism allows you to share an object between UIMA components. You tell UIMA how to instantiate this object as part of your analysis engine description (or aggregate AE description). The object is instantiated once per UIMA root context, so should have the same scope as the session. I have no idea if external resources can be accessed from a FlowController. Your concept of "client" and that used in the documentation of the session may be slightly different. I am pretty sure the session documentation refers to a UIMA deployment which is distributed on a network. Every node (client) in that network, e.g. every UIMA-AS deployment, has its own session - they are not in any way synchronized across the network. In your case, to make sure a session (or external resource below) is not shared between clients accessing your web application, you need to make sure that your recognitionAE instance is not shared between web clients - or put it otherwise - it is not thread-safe when you store data in the session. I'd probably create a new UIMA type which holds such information and add it to the CAS. That way, the CAS has some metadata on how it was processed and it can be accessed by the FlowController. This also restores the thread-safety and if your annotator is programmed in a thread-safe way, you can instantiate it once and share it between all your clients. Since the instantiation of an analysis engine can be a costly process, you may want to consider that.

RE: Sessions
Thanks for the suggestion. I ended up casting like this:
FlowControllerContext_impl fcContext =
(FlowControllerContext_impl)getContext();
This is in my custom flow controller, so getContext() is a superclass
(FlowController_ImplBase) method.
The reason I want to use a session object to store my properties is that
the API says these sessions are per client. My UIMA app is running in a
JBoss container that is accessed by a web service call. So multiple
clients could be accessing it simultaneously, each one passing slightly
different parameters. In the web service method I do this:
protected AnalysisEngine recognitionAE;
...
recognitionAE.getUimaContext().getSession().put(STEMMER_KEY_NAME,
stemmerAlgorithmKey);
Then later in my custom flow controller I want to get this property and
use it to control the flow.
I'm not familiar with the external resource support. Can I do something
similar using that?
Thanks,
Larry

With a cast I think you can get the root context and use its session
object.
Session rootSession =
((UimaContextAdmin)aContext).getRootContext().getSession();
Note that the the Javadocs say developers should not use this interface!
It may be preferable to use the external resource support to share a map
amongst annotators.

Re: ConceptMapper dictionary entry variant
There are a few ways this can be done, depending on your needs. 1. Set the "ResultingAnnotationMatchedTextFeature" parameter in the descriptor. This should be the name of a String feature in your result annotation (e.g., DictTerm is used in the distributed example). In the resulting annotation instance, it will be filled with actual text that was matched in input document. 2. Set the "MatchedTokensFeatureName"parameter in the descriptor. This should be the name of an FSArray feature in your result annotation, and will be filled with tokens matched in input document. 3. Add some other indicator into your dictionary (e.g., a simple unique identifier for each variant, or perhaps an id for the parent and one for the variant--depends on your needs). Then use the fact that you can map any attribute in the dictionary into the resulting annotation by setting up the parameters "AttributeList" and "FeatureList". Let me know if this make sense, or if you need more information. Looking back at the documentation, I can see that things really need to be clarified a lot--sorry!

Re: UIMA in EU projects?
Hi Jens, back in 2009 I did a small presentation about UIMA and semantic search [1] for IKS EU project [2]. IKS then promoted the creation of the Apache Stanbol project [3] (which basically contains almost the entire codebase for the project) which also integrates Apache UIMA [4][5]. Hope this helps, Tommaso [1] : http://uima.apache.org/iks09.html [2] : http://www.iks-project.eu [3] : http://stanbol.apache.org [4] : http://blog.iks-project.eu/uima-apache-stanbol-integration/ [5] : http://blog.iks-project.eu/uima-apache-stanbol-integration-2/ 2013/1/7 Diman Karagiozov > Hi there, > > we are using UIMA in the ATLAS EU project ( http://www.atlasproject.eu/). > > greetings > Diman Karagiozov > > > On 01/07/2013 01:18 PM, Jens Grivolla wrote: > >> Hi, >> >> I would like to find some references to the use of UIMA in EU funded >> projects.

UIMA for multimodal annotation?
Hi,
we're thinking of using UIMA for multimodal multimedia annotation (text,
video, audio, ...), but have found little information of people actually
doing that. I did find an old post by Burn Lewis about donating the GALE
type system ("Donation of a widely used type system for multi-modal text
analysis") but not much more.
Thanks,
Jens
