| Extracts numerals from financial texts and checks if they are in-claim or out-of claim | |
| Parameters: | |
| txt (str): Financial Text. This is to be given as input. Numerals present in this text will be evaluated. | |
| Returns: | |
| highlight (list): A list each element of which is a tuple. Each tuple has two elements i) word ii) whether the word is in-claim or out-of-claim. | |
| dff (pandas dataframe): A pandas dataframe having three columns 'numeral', 'prediction' (whether the word is in-claim or out-of-claim) and 'probability' (probabilty of the prediction). | |
