school of csit, rmit university
学术报告简介: big data is now around every corner of our life - data is heterogeneous, of large volume and high rate of change. a very demanding task is how to make the data usable to data consumers. data cannot make one's life better unless we provide her a way to find her expected 'needle' in such big data ocean. in this talk, i would like to give an overview of my works on improving the usability over heterogeneous data. in particular, we will talk about the usability and performance issues on structured data (mismatch problem), spatial-textual data (fuzzy type-ahead search problem), spatio-temporal data (activity trajectory search problem), and graph data (e.g. personalized realtime search over social media). last i will introduce the system we are building for an interactive and visualized exploration of the location-centered real estate data in australia for the last ten years.
