Abstract: A method performed by one or more electronic devices for ascertaining a purpose of a meeting is described. In various embodiments, calendar event data and trip data are obtained. The calendar event data and the trip data are combined to produce aggregated data. A set of feature vectors are determined for the aggregated data. A neural network is utilized to determine whether the set of feature vectors indicate a meeting. A set of purpose clusters are generated based on at least one of the set of feature vectors and user-formulated purposes and a prototype purpose is formulated for each cluster in the set of purpose clusters. At least a subset of the feature vectors is mapped to one cluster of the set of purpose clusters in response to determining that the feature vectors indicate a meeting. The prototype purpose for the mapped cluster for the indicated meeting is presented.
