Revisiting Cross-Lingual Summarization: A Corpus-based Study and A New Benchmark with Improved Annotation

ConvSumX

ConvSumX is a cross-lingual conversation summarization benchmark, through a annotation schema that explicitly considers source input context.

ConvSumX consists of 2 sub-tasks: DialogSumX and QMSumX, with each covering 3 language directions: En2Zh, En2Fr and En2Ukr.

This work is accepted by ACL 2023. You may find the paper here.

    abstract = "Most existing cross-lingual summarization (CLS) work constructs CLS corpora by simply and directly translating pre-annotated summaries from one language to another, which can contain errors from both summarization and translation processes.To address this issue, we propose ConvSumX, a cross-lingual conversation summarization benchmark, through a new annotation schema that explicitly considers source input context.ConvSumX consists of 2 sub-tasks under different real-world scenarios, with each covering 3 language directions.We conduct thorough analysis on ConvSumX and 3 widely-used manually annotated CLS corpora and empirically find that ConvSumX is more faithful towards input text.Additionally, based on the same intuition, we propose a 2-Step method, which takes both conversation and summary as input to simulate human annotation process.Experimental results show that 2-Step method surpasses strong baselines on ConvSumX under both automatic and human evaluation.Analysis shows that both source input text and summary are crucial for modeling cross-lingual summaries.",
