[0012]

FIG. 1 shows an overall configuration diagram of a system according to an embodiment of the present invention. In FIG. 1, a search server 10 is configured by a computer system connected to the Internet 12. A communication carrier server 14 operated by a mobile communication carrier is connected to the Internet 12, and a mobile phone 16 having an Internet connection function connects to the Internet 12 from a base station 18 via the communication carrier server 14. be able to. The search server 10 provides a web search service to the mobile phone 16 having such an Internet connection function. In the present embodiment, the mobile phone 1
Reference numeral 6 denotes an i-mode compatible mobile phone capable of displaying a page described in cHTML.

As shown in FIG. 1, the search server 10 includes a robot engine unit 20, a level determination unit 22, a data registration unit 24, a web server unit 26, a search processing unit 28, and a web page database 30.

The robot engine unit 20 periodically (for example, once a day or once a week) periodically transmits data to the Internet 1
2, traverses various WEB pages, for example, by following a link from a predetermined start WEB page, and obtains WEB page data (that is, an HTML text sentence) describing each WEB page. The level determination unit 22 determines the suitability level representing the suitability for the mobile phone 16 for each WEB page data acquired by the robot engine unit 14 with reference to the point table 22a.

More specifically, as shown in FIG. 2, the point table 22a includes various tags which are components of an HTML sentence and other predetermined symbols (hereinafter, referred to as tags, etc.), meta information, and web pages. About data size,
An adaptation point indicating the degree of adaptation to the mobile phone 16 is recorded. This adaptation point is set so as to become larger as the adaptability to the display on the mobile phone 16 is higher. As shown in FIG. 2, the following point setting is performed in this example.

Tag specific to i-mode site: 5
Point For example, on a WEB page for i-mode, pictograms can be expressed by designating a 2-byte numerical value within a predetermined range after "&#". Therefore, it can be determined that the WEB page including the numerical value within the above predetermined range following the symbol “&#” is a site for i-mode. So, "&#[XXYY]"
(XXYY is the above 2-byte numerical value), 5 points are given as conforming points. Similarly, tags <A accesskey ~>, <A href="tel:~>, <INPUT ... is
Since tyle ~>"is used only on i-mode sites,
These points are also given 5 points.

Tags and the like commonly used for i-mode sites and personal computer sites: 1-point tags <A->(<Aaccesskey->,<A href = "tel:
~>), <BASE ~>, <BLOCKQUOTE>, etc. are tags commonly used for personal computer sites and i-mode sites. That is, just because these tags are included does not mean that the site is for i-mode,
There is no problem at least on the display on the mobile phone 16. Therefore, one point is given to these tags as conforming points.

Tags, etc., which are unlikely to be included in i-mode sites, but do not hinder display on mobile phones even if they are included: 0 point tags <ADDRESS>, <BIG>, <CODE>, etc. Although used only for sites for personal computers, even if these tags are included, there is no particular problem with the display on the mobile phone 16. That is, since the compatibility with the mobile phone 16 is neutral, 0 points are given as the matching points.

Tags etc. that may adversely affect the display on the mobile phone: -1 point For example, tags <CAPTION> and <TABLE> are tags used for table display, and may disturb the display on the mobile phone 16 There is. In this way, a tag that may adversely affect the display on the mobile phone 16 is given -1 point as a matching point.

Tags etc. which are premised on browsing on a personal computer and which have a large possibility of adversely affecting the display on a mobile phone: -3 point tags <FIELDSET>, <LEGEND> are tags relating to fields, and , <LINK> are tags relating to the style sheet, and in any case, the display on the mobile phone 16 is likely to disturb the display on the mobile phone. A tag that is likely to adversely affect the display on the mobile phone 16 is given -3 points as a matching point.

Tag or the like that is likely to cause a serious obstacle to the display on the mobile phone: -50 points For example, the tag <APPLET> is a tag for designating a JAVA (registered trademark) applet, and the tag <AREA > Is a tag for specifying a clickable map. If a web page including these tags is to be displayed on the mobile phone 16, it is certain that adverse effects such as a large disturbance in the layout will occur. The character code used on the web page is a code other than SJIS,
Or, if the media type of the web page is "text / htm
If the value is other than "l", "text / plain", or "image / gif", display cannot be performed on the mobile phone 16. In this way, a serious obstacle to display on the mobile phone 16 may occur. Since a reliable tag or the like has no suitability for the mobile phone 16 at all, -50 points are given as a matching point.The character code used in the web page is obtained by analyzing the web page data. The media type is determined when the robot engine unit 20 accesses the web page.
It is obtained by inquiring the WEB page about the media type.

When the data size exceeds the upper limit that can be displayed: -50 points An upper limit is set for the data size of the WEB page that can be displayed by the mobile phone 16, and the data size of the WEB page is set to this upper limit. Size (for example, 5k bytes)
If the number exceeds the limit, it cannot be viewed on the mobile phone 16. Therefore, if the size of the web page data exceeds the above upper limit size,-
50 points will be awarded.

Note that the point setting shown in the point table 22a of FIG. 2 is merely an example, and each matching point may be determined as appropriate so as to reflect the degree of suitability of the mobile phone 16 for displaying a WEB page.

The level determination unit 22 extracts tags and the like from the WEB page data acquired by the robot engine unit 20, and refers to the above-mentioned point table 22a for each tag and the like, meta information and page data size, and matches the corresponding points. To get. Then, the matching points are accumulated for the web page data, and the accumulated point number is set as the matching level of the web page data. that time,
If any of those matching points contains -50 points, the W
The relevance level of the EB page is -50.

On the other hand, the data registration unit 24 divides text information included in each WEB page data acquired by the robot engine unit 20 into word levels by morphological analysis so that keyword search processing described later can be performed at high speed. Then, a search index file is created. Then, this text information is stored in the U
In addition to recording in the web page database 30 in association with the RL, the compatibility level determined by the level determination unit 22 is recorded in association with the URL of the corresponding web page.

Next, the search server 1 is sent from the mobile phone 16.
The processing when access to 0 is performed will be described with reference to the flowchart shown in FIG. As shown in FIG. 3, when there is access from the mobile phone 16, first, in step 100, a search screen is transmitted from the WEB server unit 26 to the mobile phone 16. The search screen is provided with a keyword input field, and the user inputs a search keyword in this keyword input field and makes a search request.

At step 102, the search keyword input on the search screen is received, and the search keyword is passed to the search processing unit 28.

In step 104, the search processing unit 28 searches the web page database 30 for a web page that includes the search keyword in the text information with reference to the web page database 30 (primary search).

In step 106, the relevance level of each web page extracted in the primary search is acquired from the web database 30 in the search processing unit 28. Next, the acquired conformity level is set to a predetermined value (for example,-
50) The following web page is excluded from the primary search results as a site that cannot be displayed on the mobile phone 16 (secondary search). Then, the remaining WEB sites that have not been excluded are sorted in descending order of the relevance level.
It is delivered to the EB server unit 26.

In step 108, the web server unit 2
6 generates a search result screen displaying the secondary search result passed from the search processing unit 28 and transmits the search result screen to the mobile phone 16.

As described above, in the present embodiment, when a search request is issued from the mobile phone 16, the WEB page whose compatibility level is equal to or lower than a predetermined value (that is, the mobile phone 1).
6 can be excluded from the search results and presented to the mobile phone 16. That is, only the browseable WEB page is displayed as a search result on the mobile phone 16. in this way,
According to the search server 10 of the present embodiment, it is possible to provide a user-friendly search service for mobile phones without displaying unnecessary search results.

Further, on the search result screen, WEB pages corresponding to the search conditions are displayed in descending order of matching points. For this reason, the user can select each WEB from the search result screen.
The degree of adaptation of the page to the mobile phone 16 can also be known.

The function of the portable telephone 16 may be different depending on the model. Therefore, the setting of the matching point may be changed in accordance with the difference in the function of each model. For example, in the above embodiment, it is assumed that the image data format that can be displayed on the mobile phone 16 is only the GIF format, and if the media type is other than “image / gif”, the display on the mobile phone 16 is not suitable. -50 points are awarded as no. However, some models can display image data in JPEG format or PNG format, and in such models, even if the media type is "image / jpeg" or "image / png", there is no compatibility. You should not judge. In such a case, by determining the adaptation point according to the media type according to the model of the mobile phone 16, the suitability for the mobile phone 16 can be correctly determined. In addition, when tags and the like that can be processed differ depending on the model, not limited to the image data type, the matching point for each tag and the like may be changed according to the difference, and
When the maximum data size that can be displayed differs depending on the model, -50 points may be given when the size of the web page data exceeds the maximum data size. At the time of access from the mobile phone 16, information about the model of the mobile phone 16 is transmitted to the search server 10, so that the model of the mobile phone 16 as the access source can be detected based on this information.
