The value of showing important, yet separated, parts of a document simultaneously motivates head-tail display. 35% of Web documents tested benefit. A head-tail display provides a querydependent view of a document using a split window. One subwindow shows the beginning of the document, a particularly important part of many documents. The other subwindow shows the query-relevant document “tail,” starting from the first query term occurrence.
