The SentenceExtractor function extracts sentences from English input text. A sentence ends with a punctuation mark such as period (.), question mark (?), or exclamation mark (!).
Many Natural Language Processing (NLP) processing tasks (such as Part-Of-Speech tagging and chunking) begin by identifying sentences.
SentenceExtractor uses files that are preinstalled on ML Engine. For details, see Preinstalled Files That Functions Use.
