摘要：Missing data is ubiquitous. It generally has incompleteness or uncertainty property, and widely exists in many real-life applications such as sensor networks, data integration, society survey, etc. Query processing plays an increasingly important role in these scenarios, especially for obtaining valuable information from complex missing data. However, traditional query techniques on complete data cannot (directly) support querying missing data. I will give a talk with the title of complex missing data query and management. My talk is mainly divided into four parts, including (i) querying incomplete data, (ii) querying uncertain graphs, (iii) optimizing query quality involving data uncertainty, and (iv) an application system with queries on missing data.
