Using Intelligent Word Recognition (IWR)

Help Center RecognitionLast updated: 20 January, 2020

Intelligent word recognition, or IWR, is the recognition of unconstrained handwritten words. IWR recognizes entire words or phrases instead of individual characters Optical Mark Recognition, or OCR is using. For instance, when trying to extract the word 'paper' using OCR system, it will recognize all characters one by one ('p', 'a', 'p', 'e', 'e', and 'r'). On the other hand, the IWR will match letters to a user-defined dictionary to extract the whole word 'paper'. IWR significantly reduces character errors.

How to usit it?

To use IWR in Papersurvey.io go to Surveys -> Verify section and click the Dictionary tab. This will be helpful when you are expecting to have multiple repeating text answers that may similarly match (e.g. Course Name, Event Name, Location, Country, etc.).

IWR

To add a new verification rule click the 'Add Custom Rule' button. In the modal, select the question for which the rule should be applied (Only works with 'Short Text' and 'Number' questions).

Then select one of two methods - 'Text is similar to' or 'Text is equal to'. We recommend using 'Text is similar to' method with 'Number' questions and 'Text is equal to' with 'Short Text' questions to get the highest accuracy rates.

IWR

Enter text value which should be always accepted as a correct answer and would not need additional verification. You may add multiple values by separating each value with a line break.

IWR

After clicking 'Add', similar responses will be automatically verified.
