7. An apparatus comprising: one or more processors; memory; an acquisition unit stored in the memory and executable by the one or more processors, used for obtaining one or more search keywords used by one or more users within a predetermined time period; a statistics unit stored in the memory and executable by the one or more processors, used for counting the one or more search keywords to obtain a primary keyword, one or more related keywords associated with the primary keyword, one or more co-search frequencies of the primary keyword and the one or more related keywords, and a search frequency of the primary keyword; a first computation unit stored in the memory and executable by the one or more processors, used for computing a first feature value based at least in part on the search frequency of the primary keyword; and a second computation unit stored in the memory and executable by the one or more processors, used for: computing one or more correlation levels based at least in part on the one or more co-search frequencies, and computing one or more second feature values based at least in part on the first feature value and the one or more correlation levels, wherein a second feature value of the one or more second feature values is served as a parameter for determining whether a corresponding related keyword of the related keywords is to be displayed constantly or in a rotating manner.

The apparatus as recited in claim 7 , wherein the corresponding related keyword is to be displayed in the rotating manner when the second feature value is less than a threshold.
