NumClaim: A Dataset for Investor's Fine-grained Claim Detection


Numerals provide important information in financial narratives. Our statistical result in the financial analysis reports shows that over 58.47% of sentences contain at least one numeral. Without the numerals, lots of fine-grained information in the analysis reports will be lost. This phenomenon evidences the importance of the numerals in the financial narrative. Based on our observation, investors always make a claim with an estimation. This estimation can be a cue for detecting the investor's fine-grained claim. Therefore, we propose an expert-annotated dataset, NumClaim, for probing argument mining in the financial narrative. Among 5,144 instances in the NumClaim dataset, 23.78% and 76.22% of instances containing numerals are annotated as ``In-claim'' and ``Out-of-claim'', respectively.


The NumClaim dataset is consisted of "file", "text", "numeral", "offset", "category" and "in-claim" in json format.

'text': '群光2019年動能推測以影像模組、高階鍵盤表現較佳,公司影像模組客戶包括G客戶與R客戶、Logitech、SportDV等,鍵盤輸入動能則來自於高階鍵盤包括平板外接、LED發光與電競鍵盤等出貨。群光1Q~3Q18一般鍵盤收入YoY-5%~-10%,高階鍵盤收入則超逾YoY+20%,主要係受惠於微軟Surface與電競需求增溫,而其電競客戶則包括Corsair、Logitech等,另外MSI、ASUS與中國品牌亦為供應商。群光2019年預期以電競鍵盤、LED發光鍵盤因市佔率提升而表現較佳。日盛預估群光2018年EPS5.03元,並預估2019年稅後EPS5.72元,群光2H18毛利率回溫,本益比僅約10倍,落於歷史低檔,維持買進評等。',
