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.
