QMSum

Overview

This repository maintains dataset for NAACL 2021 paper: QMSum: A New Benchmark for Query-based Multi-domain Meeting Summarization.

QMSum is a new human-annotated benchmark for query-based multi-domain meeting summarization task, which consists of 1,808 query-summary pairs over 232 meetings in multiple domains.

Dataset

You can access the train/valid/test set of QMSum through the data/ALL folder. In addition, QMSum is composed of three domains: data/Academic, data/Product and data/Committee contain data in a single domain.

Files in each folder:

• jsonl: data in .jsonl format.
• all: all data in .json format.
• train: training data.
• val: validation data.
• test: test data.

The format of json data is as follows:

        {
            "topic": "Introduction of petitions and prioritization of governmental matters",
            "relevant_text_span": [["0","19"]]
        },

        },
        {
            "speaker": "Mr. Garnett Genuis (Sherwood ParkFort Saskatchewan, CPC)",
            "content": "Mr. Chair, I'm pleased to be presenting two petitions today. The first petition is with respect to government Bill C-7 ..."
        },
        ...
	{
            "speaker": "Hon. Seamus O'Regan",
            "content": "Mr. Chair, we have been working with our provincial partners. We have been working with businesses of all sizes in the oil and gas industry ...."
        },
        {
            "speaker": "The Chair",
            "content": "That's all the time we have for questions today. I want to thank all the members for taking part. The committee stands adjourned until tomorrow at noon.  The committee stands adjourned until tomorrow at noon. Thank you."
        }
    ]
}

Please note that there may be multiple relevant text spans for a topic or a specific query. The general query has no corresponding text spans because it corresponds to the entire meeting transcript.

Data Processing

We provide a notebook to convert our data into the format required by some seq2seq models like BART or PGNet. For details, see data_process.ipynb. Besides, we set the maximum source length during training to 2048 for these two models.

Models

We run many popular models in this paper. Here we provide the code that can be used to implement each model.

For our Locator, we use the code from this link. Notably, we find that removing Transformers in Locator has little impact on performance, so the Locator without Transformer is used in all the experiments.

For PGNet, you can refer to the implementation of the original paper here.

For BART, we use the interface provided by fairseq, of course you can also refer to the implementation of transformers.

For HMNet, please use the official implementation here.

Extracted Span

The spans extracted by our Locator as the input of the Summarizer can be found in /extracted_span.

Model Outputs

We provide the summary generated by HMNet (with golden input) in /model_output. The ROUGE score of this output is 36.51/11.41/31.60 (R-1/R-2/R-L).
