context token desc - apache/ctakes GitHub Wiki

This annotator creates annotations from one or more tokens, using surrounding tokens as clues. An example of an annotation created from multiple tokens is a range that includes 2 numbers

and a dash (e.g. 2-3).

See the CdtTypeSystem.xml descriptor for the list of annotation types this annotator might create.
This annotator depends on finite state machine (FSM) code in the project named core.
