Temporal Information Retrieval Revisited: A Focused Study on the Web

Temporal information retrieval has been an active area of research for a number of years. Most existing works focus on the utility of temporal information in specific types of corpora (such as news archives), specific types of retrieval approaches, and, specific applications that may benefit from temporal information (such as timeline summarization). Underrepresented in existing works are studies that investigate the impact of temporal information analyses on the Web and Web documents. In this paper we (i) describe the research gaps we identified around Web-based temporal information analysis, and, (ii) present an overview of our first results and observations when studying sub-document timestamping on the Web.
