  Intent detection and slot filling are important tasks in spoken and natural
language understanding. However, Vietnamese is a low-resource language in these
research topics. In this paper, we present the first public intent detection
and slot filling dataset for Vietnamese. In addition, we also propose a joint
model for intent detection and slot filling, that extends the recent
state-of-the-art JointBERT+CRF model with an intent-slot attention layer in
order to explicitly incorporate intent context information into slot filling
via "soft" intent label embedding. Experimental results on our Vietnamese
dataset show that our proposed model significantly outperforms JointBERT+CRF.
We publicly release our dataset and the implementation of our model at:
