Abstract: Systems and methods for inferring and contextualizing a stranger on an enterprise platform are provided. The method includes generating a familiarity score between a user and an individual. Based on the generated familiarity score, the individual is determined to be a stranger to the user and a contextualized summary of the stranger is generated. The generated contextualized summary of the stranger is presented to the user in response to an upcoming interaction between the user and the stranger or a detected interaction between the user and the stranger.

Abstract: Systems and methods for inferring and notifying an end user about reduced availability of a target user or group of target users in a time range of interest. For instance, the reduced availability service includes components for collecting calendar event information and calendar settings information corresponding to a calendar of a target user, generating an interval graph data structure based on the collected calendar information, determining working hours for the target user, identifying periods of time where reduced availability is determined in the target user's calendar, and generating a notification of the target user's reduced availability for alerting the end user.

Abstract: A method for detecting and exposing user communication preferences within a communication application includes accessing a user profile datastore to retrieve an inferred communication preference from each of a plurality of user profiles. The method further includes storing, within each of a plurality of contact cards of a communication application, the inferred communication preference downloaded from a corresponding one of the plurality of user profiles in the user profile datastore; detecting, via a user interface of the communication application, a user interaction with a user interface element associated with a select one of the contact cards; and responsive to detecting the user interaction, presenting, on the user interface of the communication application, the inferred communication preference stored within in the select one of the contact cards.
