Given a TaSK query, we continuously maintain up-to-date top-k most relevant results over a stream of geo-textual objects (e.g., geo-tagged Tweets) for the query. ...
Massive amount of data that are geo-tagged and associated with text information are being generated at an unprecedented scale. These geo-textual data cover a wide range of topics. ...
These geo-textual objects can be modeled as continuously arriving streams, and many real-world applications can benefit from a publish/subscribe system for streams of such geo textual objects. ...
