Yichen Hu is currently working on temporal record linkage. Record linkage has been a research topic since 60s, it is about resolving records from different databases (such as databases from hostipitals, insurance companies, surveys etc.) to the real person to which the records refer. Record linkage techniques can also be used for the same type of databases but with records collected at different point of time, such as census and civil registry databases.
Temporal record linkage addresses the record linkage problem for databases with temporal information and uses the temporal information to improve the quality of record linkage.
