NTCIR FinNum Task data(Research Purpose Use of Test Collection)


Numeral is the crucial part of financial documents. In order to understand the detail of opinions in financial documents, we should not only analyze the text, but also need to assay the numeric information in depth. Because of the informal writing style, analyzing social media data is more challenging than analyzing news and official documents. FinNum is a dataset for fine-grained numeral understanding in financial social media data - to identify the category of a numeral.

Task data




In provided dataset, participants will get "idx" (the index of the tweet), "id" (the id of the tweet), "target_num" (the target numeral), "category" (annotated result), "subcategory" (annotated result), and should rebuild the data via Stocktwits API. Note that, three categories (Indicator, Quantity, and Product/ Version number) do not have subcategory. Thus, the category and subcategory information are the same for these three categories.
