Typical predicate semantic arguments include Agent, Patient, and Instrument, but semantic roles may also be found as adjuncts (., Locative, Temporal, Manner, and Cause). The identification of such event frames holds potential for significant impact in many NLP applications, such as Information Extraction, Question Answering, Summarization and Machine Translation. Recently, the.
