PUB-R

This is the code and data of six expeiments mentioned in the paper "PUB-R: End-to-End TOD System via Turn-Based Positioning".

Description

Setting	Description	Action Span Used	Positioning Representation
1	Original method used in the 2021 AAAI paper UBAR	Y	-
2	Try to remove action span from Setting 1	N	-
3	Our final method - TPEM	Y	ATP
4	Try to remove action span from Setting 3	N	ATP
5	TPEM-variant 1	Y	RTP-F
6	TPEM-variant 2	Y	RTP-P

Requirements

• CUDA 10.1
• Python 3.6
• PyTorch 1.5
• spaCy
• transformers 2.11

We use the tokenization tool in SpaCy which can be installed through:

python -m spacy download en_core_web_sm

Data Preprocessing

The original data files are put under data/multi-woz, which includes:

• data.json: The orignal MultiWOZ 2.0 data released by researchers in University of Cambridge.
• annotated_user_da_with_span_full.json: A preprocessed and fully annotated version of MultiWOZ 2.0 data released by developers of Convlab. We mainly show the implementation process on MultiWOZ 2.0. If you want to implement later versions you'll have to get the dataset yourself and change the corresponding paths in the scripts or use the scripts postfixed with "21".
