讲座摘要:

In the past few years, the wide application of online map applications and location based services has significantly changed the ways of our life. Today, it is typical for us to search for directions or businesses on the Internet and find our ways through navigation services using cell phones. Lots of the location based services require providing answers to users continuously so that the users can interact with the applications in real time. For example, a tourist may ask for the nearest three restaurants to be reported continuously while traveling in a city, so that he or she may choose one at any time. As the answers may change over time, the continuous nature of the applications poses new challenges on the methods for processing the queries with extremely high efficiency. In this talk, we look at a few key strategies to process location based queries in a streaming fashion such as incremental and shared computation, safe regions, and time-constraint processing. These strategies are illustrated through the algorithms to several important types of continuous location based queries. We will also look at how the spatio-temporal queries develop and what are the current research trends in this area.
