Topic Tracking is one of the important tasks of TDT.And temporal information plays a role in describing a topic.In this paper,we discusses how to embed temporal information in Topic Tracking system and compares the reciprocal manner with the span-cross manner.Experiments show that the span-cross manner displays better in improving the TT system performance.
