10. A system comprising: a query monitoring module to: monitor search queries associated with a search query category, the search query category associated with at least one search term and associated with a baseline frequency, the baseline frequency reflecting an average number of search queries detected during a time interval associated with the search query category, and detect a change in a search request frequency associated with the search query category with respect to the baseline frequency; an event detecting module to determine an event associated with the search query category; an item identifying module to identify one or more data items associated with the event, the one or more items comprising at least one item listing associated with an item for sale; and at least one processor to run a display generation module configured to generate a visual representation of a relationship between the one or more data items and the event, the display generation module configured to display the at least one item listing such that the at least one item listing appears visually related to the event.
