convlab2.nlu.svm.multiwoz.evaluate module

Evaluate SVMNLU models on Multiwoz test dataset

Metric:

dataset level Precision/Recall/F1

Usage:

PYTHONPATH=../../../.. python evaluate.py [usr|sys|all]

convlab2.nlu.svm.multiwoz.evaluate.da2triples(dialog_act)

convlab2.nlu.svm.multiwoz.nlu module

SVMNLU build a classifier for each semantic tuple (intent-slot-value) based on n-gram features. It’s first proposed by Mairesse et al. (2009). We adapt the implementation from pydial. For more information, please refer to convlab2/nlu/svm/multiwoz/README.md

class convlab2.nlu.svm.multiwoz.nlu.SVMNLU(mode='all')

Bases: convlab2.nlu.nlu.NLU

predict(utterance, context=[])

Predict the dialog act of a natural language utterance.

Args:
utterance (str):

A natural language utterance.

Returns:
output (dict):

The dialog act of utterance.

convlab2.nlu.svm.multiwoz.preprocess module

Preprocess multiwoz data for SVMNLU.

Usage:

python preprocess [mode=all|usr|sys] mode: which side data will be use

Require:

  • ../../../../data/multiwoz/[train|val|test].json.zip data file

  • ../../../../data/multiwoz/db database dir

Output:

  • configs/ontology_multiwoz_[mode].json ontology file

  • data/[mode]_data/ processed data dir
