Hi Masoud, In this link - https://cwiki.apache.org/confluence/display/CTAKES/cTAKES+4.0+-+Fast+Dictionary+Lookup, I could see an information stating " A paper on rare word indexing is currently in progress."
May be Sean or Tim will be able to provide info on this I feel.

As a part of our comparisons, we are exploring the architecture of the NER and (UMLS) concept linking components of the tools. I was able to find the description on the cTAKES default/original dictionary look up in the Savova et. al. 2010 paper but I was not able to find a paper or tech report describing the fast UMLS dictionary lookup (Fast UMLS Processor) yet. Any description of the fast dictionary lookup algorithm is highly appreciated.
