The sentence splitter uses a detailed set of hand-coded rules (adapted from Sekine's OAK system) to divide a span of text into sentences. It adds sentence annotations spanning each sentence.
A question mark or exclamation mark always ends a sentence. A period followed by an upper-case letter generally ends a sentence, but there are a number of exceptions. For example, if the period is part of an abbreviated title ("Mr.", "Gen.", ...), it does not end a sentence. A period following a single capitalized letter is assumed to be a person's initial, and is not considered the end of a sentence.
