Continuous Summarization of Streaming Spatio-Textual Posts
Abstract
In this paper, we address the problem of continuously maintaining a concise, diversified summary of the contents of a sliding window over a stream of geotagged posts. Selecting posts to include in the summary takes into account both the criteria of coverage and diversity, and the summary is updated dynamically when the window slides. Our proposed strategy provides a trade-off between information quality and performance. An experimental evaluation of our method is presented using two real-world datasets containing spatio-textual posts from Twitter and Flickr.
