By executing step S23 or step S26, the URL acquired in step S17
URL information including information and U corresponding to the URL information
RL and are acquired. Hereinafter, the URL and the URL information acquired in step S23 or step S26 are related U
It is called RL. Multiple related URLs may be obtained,
In some cases, you cannot get it at all.

In step S27, when the related URL is obtained, the output content is generated by associating the obtained related URL with the URL information. The generated output content is described in HTML in this embodiment. Note that the output content may not be described in HTML, but may be data obtained by associating the obtained related URL with the URL information.

The output content generated in step S27 is stored in the output HTML 115 of the storage unit 110 (step S28).

FIG. 7 is a flowchart showing the flow of the new arrival information search processing executed in step S23 of FIG. Referring to FIG. 7, in step S31, the hyperlink [I] of the new arrival information [J] is acquired. The hyperlink [I] of the new arrival information [J] is acquired from the new arrival information database 113.

The new arrival information [J] is an array of a plurality of new arrival information stored in the new arrival information database 113. The new arrival information [0] indicates the latest new arrival information, and the created date and time is old. As the numbers increase, the sequence numbers increase. The variable J is an integer. The hyperlink [I] indicates a hyperlink of the content included in the new arrival information [J]. The variable I is an integer, and the hyperlink [0] is assigned to the first content and the hyperlink [I] is assigned to the second content in the order of the hyperlink [1]. The hyperlink [I] includes a URL and URL information for specifying the content included in the new arrival information [J].

Then, it is determined whether or not the content specified by the URL acquired in step S16 of FIG. 6 is image data (step S32). The URL acquired in step S16 of FIG. 6 is the URL of the content designated by the user of the information display device 100 clicking with the mouse or the like of the input device 155.

If the content is determined to be image data, the process proceeds to step S34, and if not, the process proceeds to step S33.

In step S33, since the content is not image data, a search is performed using the anchor character string of URL information corresponding to the content as a search keyword. If the anchor character string is a sentence, morpheme analysis is performed, the noun phrase is extracted, and the search keyword is cut out. This search keyword is compared with the hyperlink [I] of the new arrival information [J] acquired in step S31.

The hyperlink [I] of the new arrival information [J] may include an anchor character string, an image text and an extension. In this step, either the anchor string or the image text is compared. That is,
When the content specified by the hyperlink [I] of the new arrival information [J] is image data, the image text is compared, and when the content is not image data, it is compared with the anchor character string.
As a result of the comparison, if the search keyword is included in the anchor character string or the image text included in the hyperlink [I] of the new arrival information [J], the hyperlink [I] of the new arrival information [J] is extracted. If not, it is not extracted.

On the other hand, in step S34, since the clicked content is image data, the image text of the URL information of the content is used as a search keyword for the search.
If the image text is a sentence, morphological analysis is performed, the noun phrase is extracted, and the search keyword is cut out. This search keyword is compared with the hyperlink [I] of the new arrival information [J] acquired in step S31. As a result of the comparison, if the search keyword is included in the anchor character string or the image text included in the hyperlink [I] of the new arrival information [J], the hyperlink [I] of the new arrival information [J] is extracted. If not, it is not extracted.

UR of the clicked content after execution of either step S33 or step S34
The extension of L is hyperlink [I] of new arrival information [J]
It is determined whether the extension is the same or not. If the extension is the same, the hyperlink [I] of the new arrival information [J] is extracted.

Then, step S33 or step S
34 and the URL of the hyperlink [I] of the new arrival information [J] extracted in either step S35 is related U
RL is set (step S36).

At the next step S37, 1 is added to the variable I. This is because the next hyperlink is targeted for processing in order to sequentially process the hyperlinks included in the new arrival information [J].

In step S38, it is determined whether or not the new arrival information [J] has the next hyperlink [I] (step S38). If the hyperlink [I] included in the new arrival information [J] exists, the process returns to step S32.
If it does not exist, the process proceeds to step S39.

In the next step S39, 1 is added to the variable J. This is to select the next new arrival information in order to execute the search processing of the new arrival information for all the new arrival information stored in the new arrival information database 113.

At step S40, whether there is new arrival information [J] to be processed next, or whether it is set to a mode in which the new arrival information search processing is executed only for the latest new arrival information. To be judged. If the new arrival information [J] to be processed next does not exist, or
If only the latest new arrival information is selected, the process ends, otherwise, the process proceeds to step S32. In step S40, if all the new arrival information is selected in step S22 of FIG. 6, it is determined whether or not there is new arrival information [J] to be processed next. Further, when only the latest new arrival information is selected in step S21 of FIG. 6, the process ends as it is.
