In FinNum-1 and FinNum-2, we focus on understanding the numerals in financial social media data. The task of understanding the meaning of numeral (FinNum-1) and the numeral attachment issue (FinNum-2) are explored. In FinNum-3, we pay attention to formal documents (professional analyst's report and earnings conference call), and propose multilingual datasets (Chinese and English) for participants to explore on new numeral-related task, named fine-grained claim detection.
