Subject RE: Regarding using cTakes production environment..

The models are generally read-only in the runtime prod environment- so there shouldn’t be
any reason why it can’t be made to be thread-safe.
LVG[1] was definitely one I remember that was problematic...

ytex has a web client for the semantic similarity service, but not for running ctakes pipelines.

I believe that the only issue with running ctakes (or any UIMA pipeline) in a web server is
thread safety - not all AnnotationEngines are thread safe (in fact I don't know which ones
are or aren't).  What is *not* thread safe is LVG, which is not needed for many use cases.

What really needs to be thread safe are all the models - they take up a lot of memory and
instantiating one per thread would be very costly.

If you were just looking to ‘package’ up your binaries, you may want to take a look at
the ctakes-distribution [1] module.
Essentially, if you do a mvn package, it will compile all of your modules and package them
up nicely into a single zip.

I am not completely sure of the architecture when you mean “by calling this from a different
web application which is written in a different language.”  But I presume you would need
to wrap cTAKES inside a service call of some sort.  I *think* ytex has a web client [2], or
you can also take a look at the simple web app (war) [3] in sandbox.

Subject: Regarding using cTakes production environment..


I have used cTakes developer version from eclipse. I have done some modifications to the code.
I want to now compile them into single jar file and using them for production version. I am
using maven for bundling them into single jar and then use them. Can anyone tell me if they
have done this ? Are can you suggest some ideas for using cTakes in a production environment.
I want to call this from different web application which is written different language.
