Subject RE: UIMA Addons ConceptMapper - where to start

Marshall, you are right. It is the import problem.

It took me a little while to figure this out. So I think I should share with
others so new users won't have this problem again. 

The main example descriptor in ConceptMapper is: 
desc/analysis_engine/primitive/ConceptMapperOffsetTokenizer.xml

To make it work, apart from copying the descriptor xml files to your desc
folder, you need to do the following:

1. Open the following files using a text editor and delete all elements
inside the import tags
	OffsetTokenizerMatcher.xml
	ConceptMapperOffsetTokenizer.xml

2. Copy a TokenAnnotion.xml from the ConceptMapper package in the source
release to your desc folder

3. Open the above xml files using Component Descriptor Editor and manually
add the deleted items back to using import tag

Regards,

Debbie
