[ruta] How to efficiently delete an annotation only if it appears within the N first token of a document?

[Alexandre Patry]

Hi,

I use RUTA and I want to delete an annotation if it is within the first 
50 tokens of a document. I came up with the following rules :

   ANY{POSITION(Document, 1)-> Header};                // Annotate the
   first token in the document
   Header{->SHIFT(Header, 1, 2)} ANY[0,49];            // Appends the
   49 following tokens
   ToDelete{POSITION(Header, 1) -> UNMARK(ToDelete)};// Delete the
   first ToDelete if it is within the header


These rules work as expected but they are *really* slow. Is there a 
faster way to achieve that?

Thanks,

Alexandre
