http://ptp.bitplan.com uses https://github.com/WolfgangFahl/ProceedingsTitleParser/blob/master/storage/query.py
this would also be useful for https://confident.dbis.rwth-aachen.de/dblpconf/ - so migrate here to make it available for other projects.
