Abstract: This disclosure describes techniques implemented partly by a cloud-based service provider for providing a sentiment-analysis service to determine whether sentiments, or attitudes, of users have significantly decreased. The sentiment-analysis service is composed of various services provided by the cloud-based service in order to determine significant negative deviations in sentiment of users towards an entity. Further, the sentiment-analysis service utilizes various techniques, such as encryption, to privatize the process such that private user information is protected. In some examples, an entity may not know the content of communications or the reasons the user's sentiment has dropped, but may be alerted of a general negative change in sentiment towards the entity by the user.
