| Research Abstract |
This research has resulted in several novel methods and approaches for temporal information retrieval. First, we have provided methodology for estimating reference time of documents, which represents the time period to which the given document content refers to. For improving temporal information retrieval, we proposed a method for extracting collective future-related information from large document sets.
In another work, we have proposed a method for estimating age of images. Moreover, we have measured the extent to which users use time and temporal features in their search activities on the web. This online survey has been done on 110 Web users and its results were published at TempWeb2013 workshop. To further foster the research in temporal information retrieval we established Temporal Information Access task challenge in NTCiR. And we wrote a survey paper about Temporal Information Retrieval which is scheduled to appear in this year in ACM Computing Surveys journal.
