Re^2: End of sentence regex excluding " i.e." and " e.g."

In general, for a corpus like this, I'd split it into known good, known bad, and grey, and then use test-driven development in order to build out my filter.

That's what I'm doing, but I got stuck at the early stage of handling just the cases of " e.g." and " i.e.", and I'm asking how to get unstuck so I can follow your advice, which I already was doing.

__DATA__
Perl filehandles are streams, but sometimes they just aren't powerful
enough.  This module offers to have streams from filehandles searched
with regexes and allows the global input record separator variable to
contain regexes.  Thus, readline() and the <> operator can now return
records delimited by regular expression matches.  There are some very
important gripes with applying regular expressions to (possibly
infinite) streams. Please read the CAVEATS section of this
documentation carfully.  Some bunnys are fluffy, e.g. Peter.  H.G.
Wells was a great author.  Some sports require specialized
equipment, e.g. baseball.

Debugging is hard without particular examples from your corpus.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.
