Subject Re: ConceptMapper: Performance Matrix

The short answer is "no". Not yet, anyway.

But, here are some things that might help. First, if dictionary  
loading times are long, you can use the command line tool supplied in  
the package to compile the dictionary, and use the compiled  
dictionary. If you do this, remember that you will need to change the  
AE descriptors to use the correct implementation of the dictionary  
loader, e.g.:


That said, if you are using 13 dictionaries, that means you are  
running 13 copies of ConceptMapper in your pipeline, which means that  
you are traversing each file's text  at 13 times just for your  
ConceptMapper invocations. If you could merge the dictionaries into  
one, you should see a marked speedup. Clearly, it a near-term  
enhancement of ConceptMapper would be to enable the loading of  
multiple dictionaries, which get merged at initialization time.

One side note: I am going to be on vacation starting on June 25 and  
will only have occasional access to email until I return on July 12. I  
will try to answer questions during that time when I do have access,  
but I really have no idea how often that will be.
