operationalProperties

[Andreas Niekler <an...@informatik.uni-leipzig.de>]

Dear List,

can please anyone comment on the effect that the following settings in a 
analysisEngineDescription have? I wonder if they change the order of the 
processing in a multi-threaded run of a cpe. Does is change anything if 
i set those parameters or is it just to control things from outside?

I ask because i need to log which files where able to run through all 
processes Annotators since many of the annotators contanct web services. 
In the cas consumer i than write the list to a file. But what if there 
is one process that says modifiesCas=false. If an error happens in there 
does the CAS Consumer care and end the Chain or does it just don't care? 
IS there a documentation on this?

<operationalProperties>
       <modifiesCas>true</modifiesCas>
       <multipleDeploymentAllowed>true</multipleDeploymentAllowed>
       <outputsNewCASes>false</outputsNewCASes>
  </operationalProperties>

Thank you all

Hello Andreas,

as far as I know, the CPE executes components (casProcessors) in the order that they are defined in the CPE descriptor.

outputsNewCASes: should be set to true on a CAS multiplier. Mind that CPEs do not support these.

multipleDeploymentAllowed: the CPE creates multiple instances on all components with this set to true (usually AEs). Once the CPE hits the first component with this set to false, all following components are only instantiated once.

modifiesCas: I think this has no particular effect in a CPE. No idea really where this is used. A quick search on the UIMA source code didn't seem to produce any location where this setting has any effect.

Best,

-- Richard
