Research Abstract

Dealing with temporal variations of objects such as people and organizations is one of the important technical challenges to enable object-level search engines that treat an object as a retrieval unit. The contributions of this research include formalization of identifying time-varying objects as a cross temporal link prediction problem that infer the links among data in different time periods and development of a machine learning method that can enable accurate predictions.
