Sean, When I tried with pattern based approach , during the testing we got into issues for correctly identifying the segments. I was searching for better solution and could find couple of articles talks about NLP and statistical model based approaches. See below couple of links. Let me know if you have any insight into these approaches.

You could take a look at the BxvRegexSectionizer in ctakes-core. It is a little more robust than the CDASegmentAnnotator, but they are both pattern-based. One immediate advantage is that the BsvRegexSectionizer has a default list of section names and expressions in ctakes-core-res named DefaultSectionRegex.bsv that is much more populated than the ccda_sections.txt file. Though it is an ultimate goal, I don't know of any section annotator that can be plugged in and immediately catch every section for every domain at every institution. If you give me a little more to go on maybe I can be more helpful.

It is a pattern based annotator, I would like to know is there a better annotator available to segmenting the documents. It is very difficult to accommodate all the patterns in CDASegmentAnnotator as we are dealing with Medical records from multiple service providers.
