  For example, the portal site screen generation unit 110 determines the display position of the portlet so that the usage frequency becomes higher in the order of the usage frequency portlet in a predetermined time zone. Further, for example, on the portal site screen, the portlet is arranged so that the portlet with the highest access frequency is displayed at the upper left and the portlet content with the least access frequency is displayed at the lower right. At this time, the portlet arranged in the lower right may be displayed in a minimized manner. Furthermore, for example, the most frequently accessed portlet is adjusted to a size that can be displayed without scrolling by the user, and the display position is determined so as to be displayed at a position frequently used by the user (for example, above the portal site). May be.

  Further, the above-described time zone may be, for example, an arbitrary time zone immediately before the periodic access unit 230 makes a redraw request, or may be a predetermined time zone in the past (for example, one week before). This predetermined period is set in advance by the user or the administrator of the portal server 100.

  When the portal site screen (redraw screen) is generated, the portal site screen generation unit 110 transmits the generated portal site screen to the web browser 210 (S112). Thereby, the web browser 210 displays a portal site based on the received portal site screen.

  Next, a change in the display position of the portlet on the portal site will be described with reference to FIGS. FIG. 5 is a display example of the portal site based on the initial layout, and FIG. 6 is a display example of the portal site after the redrawing request is made.
