Summarization benchmark for studying corpus bias of your system

BiasSum

Data and code for "Earlier Isn't Always Better: Sub-aspect Analysis on Corpus and System Biases in Summarization " by Taehee Jung*, Dongyeop Kang*, Lucas Mentch and Eduard Hovy (*equal contribution), EMNLP 2019. If you have any questions, please contact to Dongyeop Kang ([email protected]).

We provide a platform (BiasSum.com) for bias analysis of your system across different summarization corpora. Please evaluate your summarization system across differet domains of datasets and metrics, and measure general performance on robustness against the biases.

Note

• Some codes are still under development. We will be refactoring them soon.
• If you like to add a new dataset or a new evaluation metric, please contact to Dongyeop.

Installation

Please download the pre-processed nine summarization copora in task. Every corpora has the same format of dataset as follow:

Dataset format: 
[source sentences] \t [target sentences]
or
<s> I was at home .. </s> <s> It was rainy day ..</s> ... \t <s> Sleeping at home rainy day </s> ..

An example python script for loading each dataset is provided here

python example/data_load.py --dataset AMI

Summarization Corpora

Leaderboard

• Please contact to Dongyeop if you like to add your system to the leaderboard with your R/SO/VO/PDI scores across corpora.

biassum's Issues

cannot reach the platform

Hi, Thanks for this excellent code and published leaderboard. I am trying to use it to eval one dataset. However, I can not reach the platform (http://biassum.com/), Is it still working now?

Many Thanks!
