Such annotations have potential use for studying and testing mechanisms like pronoun resolution, which are important for text understanding and machine translation. Prosodic annotation Prosodic annotation aims to indicate patterns of intonation, stress and pauses in speech. A set of 14 special characters was used to represent prosodic features. Stressed syllables were marked with a symbol indicating the direction of the pitch movement. Unstressed syllables, whose pitch is predictable from the tone marks of surrounding accented syllables, were left unmarked.
Prosody is considerably more impressionistic than other linguistic levels in corpus annotation.
