The spoken language understanding (SLU) module. During training, derivation rules are extracted based on partial sentence tree construction, and a derivation rule-dialogue act (DRDA) matrix is constructed. During testing, the trained DRDA matrix is used in DM for DA detection. Name entity class (NEC) inventory is referenced to convert certain words to word classes.
