“The ASIS&T 2008 IA Summit, Experiencing Information, emphasized users who want to know, do or share something. A user experiences information by creating, organizing, browsing and searching for information. These actions contribute to the notion of exploratory search that can be described as an information process in which the importance of a search system’s query-document matching power is diminished in favor of the user assuming a more assertive role in making decisions about the search results and the next steps toward fulfilling their information needs. A straightforward and common way to distinguish an exploratory search system is to examine the presentation of search results. Typically some browsing facilities to supplement or replace the popular list-based result pages are introduced and they feature grouping as a primary mechanism for search result display.” (ASIS&T Bulletin 34.6)
