CAIS (Chinese Artificial Intelligence Speakers)

Introduced by Liu et al. in CM-Net: A Novel Collaborative Memory Network for Spoken Language Understanding

We collect utterances from the Chinese Artificial Intelligence Speakers (CAIS), and annotate them with slot tags and intent labels. The training, validation and test sets are split by the distribution of intents, where detailed statistics are provided in the supplementary material. Since the utterances are collected from speaker systems in the real world, intent labels are partial to the PlayMusic option. We adopt the BIOES tagging scheme for slots instead of the BIO2 used in the ATIS, since previous studies have highlighted meaningful improvements with this scheme (Ratinov and Roth, 2009) in the sequence labeling field
