An IndoEuropeanSentenceModel is a heuristic sentence designed primarily for English. Whehter or not it balances parentheses or forces the last token to be a boundary may be set in the constructor. It uses the default implementation of possible sentence starts and the following token sets:

Possible Stops . .. ! ? " '' ).

Impossible Penultimates any single letter personal and professional titles, ranks, etc. commas, colon, and quotes common abbreviations directions corporate designators times, months, etc. U.S. political parties U.S. states (not ME or IN) shipping terms address abbreviations

Impossible Starts possible stops (see above) close parentheses , ; : - -- --- %

Note that all of these sets are case insensitive.
