Details:

In our continued efforts to enhance classification capabilities, we have added a new feature, Word-Breaker, to our existing Thai Language support in Classification. Words in Thai language sentences do not have spaces between them. And for classification purpose, we relied on the right keywords to be added while creating Sensitive Information Type for ensuring accurate match. However, with this feature, spaces will be added automatically in keywords which will ensure higher match accuracy across all cloud locations (Exchange, Teams, One Drive, SharePoint).

summary for non-techies**

Microsoft has introduced a "Word-Breaker" feature in its Purview compliance portal to improve keyword recognition and data protection for languages like Thai, where words are written without spaces, enhancing the accuracy of identifying and classifying sensitive information across platforms like Exchange, Teams, OneDrive, and SharePoint.

Direct effects for Operations**

Inaccurate Classification Results
Without proper preparation, the introduction of the Word-Breaker feature may lead to inaccurate classification of sensitive information, as existing keywords may not align with the new automatic spacing, resulting in missed or false positives in classification.
