Hi Harpreet,
If you are willing to use cTakes 3.2, try the dictionary-lookup-fast module as
a replacement of the default dictionary-lookup. That module has a new
dictionary resource (hsql, not lucene) and slightly different methods for
lookup and matching. In time trials it has been faster than the default module
(hence the name). Accuracy depends upon the parameter settings, but in the
tests performed so far the results are comparable or better. The new
dictionary is much leaner than the current default dictionary, small enough to
port from the hsql cached version to a hsql in-memory version. Using the
in-memory version makes dictionary lookup practically instantaneous (hundredths
of a second). Limited documentation is available in the module's doc/
directory.
I will be on vacation for a week, but please don't hesitate to write if you
have any questions.
Sean

Subject: Lucene for UMLS2014
Hello,
I would be grateful if someone could help.
I created a lucene index for umls2014 but only for snomed vocabulary.
I did this because I thought this would reduce the dictionary look up
time.
But it still almost the same. Is there any other way to improve the
dictionary look up time?
Thank you,
Harpreet
