I was just curious.

Actually, I write quite a lot rule-based annotators these days, but
always in a commercial context (and mostly for other sectors). So, I
cannot contribute them to UIMA or cTAKES unfortunately. I am still
planning to provide ready to use ASL rule-based components for Ruta, but
all the time I can invest is spent on the system itself (so that it
performs better in an industrial setting).

In case someone wants to create rule-based Ruta annotators for cTAKES,
be sure that he/she can count on my help and support.
