Abstract
Information retrieval using time is described. In an embodiment a web-crawler creates time objects which are composites of content of different media types obtained from potentially different sources and, for example, are about the same date or date range. For example, a time object may comprise an image and a piece of text about an event in 1977. In this case the time object may have the date 1977 stored with it as well as URLs of originating web pages. In an embodiment a user is able to query a search engine to retrieve time objects which are displayed in a manner related to the dates of the time objects. For example, the time objects may be displayed in chronological order against a time line. In examples time objects may be dynamically created as a web page is requested and displayed with that web page.
