Chinese Financial Announcements

The ChFinAnn dataset is a publicly available financial event dataset that includes five types of financial events: Equity Freeze, Equity Pledge, Equity Repurchase, Equity Overweight, and Equity Underweight. This dataset consists of 32040 samples and 48000 event records, of which approximately 29% of the documents contain more than one record. In addition, 98% of the records have arguments scattered across different sentences, which poses additional challenges for event extraction. This dataset was built to support document level event extraction asks, particularly in the financial field. It is not only large in scale, but also has the characteristics of multi event recording and argument dispersion, which make it a valuable resource for researching document level event extraction.

ChFinAnn数据集是一套公开可用的金融事件数据集，涵盖五类金融事件：股权冻结（Equity Freeze）、股权质押（Equity Pledge）、股票回购（Equity Repurchase）、股份增持（Equity Overweight）与股份减持（Equity Underweight）。该数据集包含32040个样本与48000条事件记录，其中约29%的文档包含多条事件记录。此外，98%的事件论元（argument）分布于不同句子中，这为事件抽取带来了额外挑战。该数据集旨在支撑文档级事件抽取任务，尤其聚焦金融领域。其不仅规模庞大，同时具备多事件记录与论元分散的特性，使其成为研究文档级事件抽取的宝贵资源。
