PureText Buyer API V3
Description: This API checks for the Open-Ended (OE) survey responses to ensure data quality. It performs language comparison, AI-generated answer detection, exclusion list checks, and response deduplication.
PureText Deduplication: Ensures the OE response is unique through deduplication.
Language Mismatch: Compares the language of the OE response with the survey language determined from the transaction ID.
AI Detection: Detects patterns to flag if the OE response is AI-generated content.
Incoherent Response: Flags the obviously unacceptable responses such as gibberish, curse words, etc
PureText can be effectively used:
For expected responses with at least one meaningful sentence (unlike categorical responses such as brand names, people and place names, etc)
Expected responses are in the same language as survey language (if the survey is in French, response should be only in French)
The API call can be made in two ways:
Individual response: after every open-ended question , or
Bulk processing: at the end of the survey for ALL open-ended responses
In either case, the API response shows you the result for each answer separately.
Please note: Upto 20 open-ended responses that can be processed in bulk at a time.
