Timely Query

Researchers have recognized the importance of utilizing temporal features for improving the performance of information retrieval systems. Specifically, the timeliness of a web document can be a significant factor for determining whether it is relevant for a search query. In this project, we focus on this important type of queries, which we refer to as timely queries. Timely queries have the following properties:

• the interest on the query from document publishers or consumers does not showsignificant variance over time (normalized by the total query traffic or document volume respectively), and
• more recently published documents are strongly preferred over older ones.
