Abstract: Embodiments for providing rare topic detection using hierarchical topic modeling by a processor. A hierarchical topic model may be learned from one or more data sources. One or more dominant words in a selected cluster may be iteratively removed using the hierarchical topic model. The dominant words may relate to one or more primary topics of the cluster. The learned hierarchical topic model may be seeded with one or more words, n-grams, phrases, text snippets, or a combination thereof to evolve the hierarchical topic model and the removed domain words are reinstated upon completion of the seeding.

Abstract: Managing a geofence of a mobile device in a network is provided, which includes: identifying, by a first application operable with the mobile device, the geofence associated with the mobile device or a user of the mobile device; based on identifying the geofence, registering the identified geofence with a network component; identifying, to a first granularity, a first location for the identified geofence; monitoring, to a second granularity, a location of the mobile device, where the first granularity is more coarse-grained than the second granularity; and based on the mobile device triggering the geofence, pushing a notification to the application; and based on receiving the notification, performing an operation associated with the geofence.
