Time is an important dimension of any information space. It can be very useful for a wide range of information retrieval tasks such as document exploration, similarity search, summarization, and clustering. Traditionally, information retrieval applications do not take full advantage of all the temporal information embedded in documents to provide alternative search features and user experience. However, in the last few years there has been exciting work on analyzing and exploiting temporal information for the presentation, organization, and in particular the exploration of search results. In this paper, we review the current research trends and present a number of interesting applications along with open problems. The goal is to discuss interesting areas and future work for this exciting field of information management.
