Joint Online Spoken Language Understanding and Language Modeling with Recurrent Neural Networks

Tensorflow implementation of joint modeling of SLU (intent & slot filling) and LM with RNNs.

This package implements joint model Number 14 and 15 in Table 1 of the below reference paper [1], i.e. the joint model with recurrent (& local) intent + slot label context. The other joint models in the paper can be made with simple modifications of generate_encoder_output.py and seq_labeling.py.

Setup

• Tensorflow, version >= r0.9 (https://www.tensorflow.org/versions/r0.9/get_started/index.html)

Usage:

data_dir=data/ATIS_samples
model_dir=model_tmp
max_sequence_length=50  # max length for train/valid/test sequence
use_local_context=False # boolean, whether to use local context
DNN_at_output=True # boolean, set to True to use one hidden layer DNN at task output

python run_rnn_joint.py --data_dir $data_dir \
      --train_dir   $model_dir\
      --max_sequence_length $max_sequence_length \
      --use_local_context $use_local_context \
      --DNN_at_output $DNN_at_output
