As shown in FIG. 1, the web server device 100 according to the first embodiment of the present invention connects to

terminal devices

201 and 202 via a computer communication network 10 (hereinafter simply referred to as the communication network 10) such as the Internet. .

When the web server device 100 receives an HTTP (HyperText Transfer Protocol) request for returning a web page from the terminal device 201 via the communication network 10, the web server output mode of the terminal device 201 is based on the received request. To decide. Thereafter, the web server device 100 replies with a web page according to the request and an instruction (hereinafter referred to as an aspect instruction) that specifies to output the web page in the determined output aspect. The web page may be any document published on the communication network 10, and includes, for example, an HTML (HyperText Markup Language) document or a PDF (Portable Document Format) document.

As shown in FIG. 2, the web server device 100 includes a CPU (Central Processing Unit) 100a, a ROM (Read Only Memory) 100b, a RAM (Random Access Memory) 100c, a hard disk 100d, a media controller 100e, a LAN card (Local Area Network). ) 100f, a video card 100g, an LCD (Liquid Crystal Display) 100h, a keyboard 100i, and a speaker 100j.

The CPU 100a performs overall control of the web server device 100 by executing software processing according to a program stored in the ROM 100b or the hard disk 100d. The RAM 100c temporarily stores information (that is, data) to be processed when the CPU 100a executes the program.

The hard disk 100d stores web server software such as Apache (Apache HTTP Server). In addition, the hard disk 100d acquires web pages published on the communication network 10 at a predetermined cycle, and stores analysis results obtained by analyzing the contents of the acquired web pages in a database. For example, a crawler or the like Memorize your Bot program. Furthermore, the hard disk 100d is a storage unit that stores a table (that is, a table) in which various types of information (that is, data) are stored. The table stored in the hard disk 100d will be described later. The web server device 100 may include a flash memory instead of the hard disk 100d.

The media controller 100e reads various data and programs from the recording medium. The recording medium includes a flash memory, a CD (Compact Disc), a DVD (Digital Versatile Disc), and a Blu-ray Disc (registered trademark).

The LAN card 100f is a receiving unit that transmits and receives data to and from the

terminal devices

201 and 202 that are connected via the communication network 10, and is a transmitting unit. The keyboard 100i inputs a signal corresponding to a user operation.

The video card 100g draws (that is, renders) an image based on the digital signal output from the CPU 100a, and outputs an image signal representing the drawn image. The LCD 100h displays an image according to the image signal output from the video card 100g. The speaker 100j outputs sound based on the signal output from the CPU 100a. The web server device 100 may include a PDP (plasma display panel) or EL (electroluminescence) display instead of the LCD 100h.

Here, before describing the software process executed by the web server apparatus 100 using the hardware described in FIG. 2, the process executed by the terminal apparatus 201 shown in FIG. 1 will be described. Since the

terminal devices

201 and 202 have the same configuration, the description of the terminal device 202 will be omitted below.

The terminal device 201 executes a reply request process as shown in FIG. 3, which transmits a request for a web page reply to the web server device 100.

When the execution of the reply request process shown in FIG. 3 is started, the terminal device 201 accepts a search keyword as shown in FIG. 4A input by the user's operation (step S01). The user is a 20-year-old woman, for example, and inputs the search keywords “boyfriend” and “present” displayed in the text box TB of FIG. This is because the user determines a present to be sent to the user's boyfriend by browsing a web page on which content related to a general present to be sent to a male during companionship is viewed.

Next, the terminal device 201 stores the search keyword in the parameter (step S02). Thereafter, the terminal device 201 searches for a web page on which the content of the search keyword is posted, and generates an HTTP request that requests the web server device 100 to return a web page representing the search result (step S03). Thereafter, the terminal device 201 adds a parameter to the URI (Uniform Resource Identifier) of the web server device 100 included in the HTTP request according to a predetermined rule (step S04). As a specific example, the terminal device 201 adds a parameter to the URI in a format representing an argument of CGI (Common Gateway Interface) or PHP (Hypertext Preprocessor). Next, the terminal device 201 transmits an HTTP request to the web server device 100 (step 05). Thereafter, the terminal device 201 ends execution of the reply request process.

1 executes a request response process as shown in FIG. 5 in response to the request for the HTTP request transmitted from the terminal device 201. Note that the CPU 100a of the web server device 100 shown in FIG. 2 executes the request response process, so that the parameter acquisition unit 120, the web page generation unit 130, the attribute specification unit 140, and the output mode determination as shown in FIG. It functions as the receiving unit 110 and the transmitting unit 160 by functioning as the unit 150 and cooperating with the LAN card 100f.

When the execution of the request response process shown in FIG. 5 is started, the receiving unit 110 in FIG. 6 receives an HTTP request from the terminal device 201 (step S11). Next, the parameter acquisition unit 120 acquires the URI from the HTTP request received by the reception unit 110, and then acquires a parameter storing the character strings “boyfriend” and “present” added to the end of the URI ( Step S12).

Next, the web page generation unit 130 represents a search result obtained by searching the web page on the communication network 10 based on the parameter acquired by the parameter acquisition unit 120 (that is, the web page requested by the HTTP request). ) Is generated (step S13). Specifically, the web page generation unit 130 posts the contents of the parameters based on the search results obtained by searching the analysis results of the web pages collected by the bot program stored in the hard disk 100d of FIG. 2 based on the parameters. A web page on which a link to the web page and a sentence representing a summary of contents posted on the linked page is generated.

Thereafter, the attribute specifying unit 140 specifies the user attribute using the parameter acquired by the parameter acquiring unit 120 (step S14). Here, the attributes include, for example, the user's age group and gender. However, it is not limited to this, and attributes include, for example, the user's educational background, annual income, occupation, work place, work area, residence area, marital status, number of dependents, smoking habits, alcohol consumption And may further include hobbies. In other words, information representing attributes (hereinafter simply referred to as attribute information) is demographic information, which is information that describes an individual and cannot be identified by itself.

Here, the process of step S14 will be specifically described. The attribute specifying unit 140, for example, assigns the attribute by the attribute information indicating the user attribute as shown in FIG. 7A and the user having the attribute. The identification character string “T, F1” associated with the keyword “boyfriend” is retrieved from a table storing information associated with information representing a search keyword that is used in the search more than users who do not have it. Note that the search keyword “present” is a keyword that almost all users use for the search at almost the same frequency, and therefore the character string “present” is not stored in the table of FIG.

Next, the attribute specifying unit 140 acquires the character “T” and the character string “F1” by separating the identification character string “T, F1” with a comma. Thereafter, the attribute specifying unit 140 searches the table shown in FIG. 7B based on the character “T” and the character string “F1”, so that the user is “male or female” who is “13 to 19 years old”. Or a woman who is “20 to 34 years old”. Here, in order to return a web page in an output mode more suitable for a boyfriend, the attribute specifying unit 140 finally specifies that the user is a woman “20 to 34 years old”.

After step S14 of FIG. 5 is executed, the output mode determination unit 150 outputs the web page generated by the web page generation unit 130 in the terminal device 201 based on the user attribute specified by the attribute specification unit 140. Output mode determination processing for determining the mode is executed (step S15). Specifically, the output mode determination unit 150 associates information indicating the user's age group with information indicating the output mode (that is, output style) of the web page in the terminal device 201 used by the user. 7 is acquired based on the user's age group “20 to 34 years” specified in step S14.

As shown in the table of FIG. 7 (d), the output style includes ruby (that is, hiragana or hiragana characters) and a mode that represents characters on a web page with a predetermined character size and non-common kanji (hereinafter referred to as emergency kanji). (A katakana name) is displayed with or without being displayed. Therefore, the output mode determination unit 150 changes the display mode of the web page based on the user's age group from “20 years to 34 years” to a ruby text size of “11” points and an emergency kanji. The mode of shaking is determined. Usually, knowledge about how to read kanji is accumulated in the user as the user gets older. Therefore, even if the user of the age group “50 years old or older” can easily read the emergency kanji, the age group is more than that. This is because it may be difficult for a user with low reading of emergency kanji.

Note that the definition that defines the output style as shown in FIG. 7D is described in a style sheet (Style シート Sheet) that defines the output mode of the web page. The definition described in the style sheet defines the output mode in the terminal device 201 used by the user as the user's age group is higher (that is, the older the user), the mode in which the character size is larger and the mode in which the ruby is less. . This is because the higher the age group, the weaker the eyesight and the more knowledge. This style sheet is stored in the hard disk 100d of FIG.

After step S15 of FIG. 5 is executed, the transmission unit 160 specifies that the web page is output in the web page generated by the web page generation unit 130 and the output mode determined by the output mode determination unit 150. The instruction is returned to the terminal device 201 (step S16). Note that the transmission unit 160 may further return a style sheet describing the determined output mode definition to the terminal device 201. Thereafter, the web server device 100 ends the execution of the request response process.

1 executes a page output process as shown in FIG. 8, in which the web page transmitted from the web server apparatus 100 is output in a manner designated by the web server apparatus 100.

When the execution of the page output process shown in FIG. 8 is started, the terminal device 201 receives the web page and the mode instruction from the web server device 100 (step S21). The terminal device 201 may further receive from the web server device 100 a style sheet that defines the output mode specified by the mode instruction.

Next, the terminal device 201 draws a web page in the mode specified by the mode instruction (that is, output style 3) (step S22). Specifically, the terminal device 201 refers to the definition of the output style 3 described in the style sheet. Thereafter, according to the definition of the output style 3, the terminal device 201 has a character size of the sentence RT1 representing the summary of the retrieved web page as shown in FIG. Draw a web page with the ruby “Bekkou” on the included emergency kanji “Shako”.

Thereafter, the terminal device 201 displays the drawn web page on the LCD provided in the terminal device 201 (step S23). Next, after the terminal device 201 receives the voice to be output on the web page from the web server device 100, the terminal device 201 outputs the received voice from the speaker included in the terminal device 201 (step S24). Thereafter, the terminal device 201 ends the execution of the page output process.

Note that the web page in FIG. 4B has a list box LB for displaying a list of output styles defined in the style sheet. For example, when the display mode of the web page is difficult to visually recognize or when the user does not meet the user's preference, the user can select one of the output styles displayed in the list box LB using the keyboard included in the terminal device 201 or To the mouse. After that, the terminal device 201 identifies the output style selected by the user based on the signal input according to the user's operation, and then changes the output style of the web page to the output style selected by the user. Display again.

Note that the user of the terminal device 201 browses the sentence RT1 displayed on the terminal device 201. In addition, when the user further displays and browses a web page representing a part of the content by the text RT1, the user operates the mouse included in the terminal device 201, for example, to operate the terminal device 201. The mouse is clicked after the displayed cursor is set to the link attached to the sentence RT1. After that, the terminal device 201 downloads the web page designated by the user according to the signal input from the mouse in response to the user's operation, and then the downloaded page has already been designated by the web server device 100. Display in output style 3.

Next, a case where the user of the terminal device 201 is a 70-year-old man and the search keywords “grandchild” and “present” displayed in the text box TB of FIG. 4C are input to the terminal device 201 will be described. .

The terminal device 201 transmits the HTTP request including the parameters storing the character strings “grandchild” and “present” to the web server device 100 by executing the processing of steps S01 to S05 in FIG.

The web server device 100 receives an HTTP request from the terminal device 201 (step S11 in FIG. 5). Next, the web server device 100 acquires a parameter storing the character strings “grandchild” and “present” from the HTTP request (step S12). Thereafter, the web server device 100 generates a web page (that is, the requested web page) representing the result of searching the web page based on the parameter contents “grandchild” and “present” (step S13).

After that, based on the parameter character strings “grandchild” and “present” and the table of FIG. 7A and the table of FIG. 7B, the attribute of the user is “male or female” of “50 years old or older”. (Step S14). Next, the web server device 100 executes the output mode determination process, so that the terminal device 201 used by the user based on the user's age group “50 years or older” and the table of FIG. The output mode of the web page is determined as “output style 5” (step S15). As shown in FIG. 7D, the output style 5 is a display mode in which the web page is displayed with the character size “18” points and the ruby “none”.

Next, the transmission unit 160 returns a web page and a mode instruction for designating the web page to be output in “output style 5” to the terminal device 201 (step S16).

The terminal device 201 receives the web page and the mode instruction from the web server device 100 (step S21 in FIG. 8). Next, the terminal device 201 draws a web page with “output style 5” designated by the mode instruction (step S22). Specifically, the terminal apparatus 201 sets the character size of the sentence RT2 shown in FIG. 4D to a size of “18” points that is “6” points larger than the size of the sentence RT1 shown in FIG. Draw and draw a web page that represents the emergency Chinese character “Kou” without ruby. Thereafter, the terminal device 201 displays the rendered web page (step S23) and outputs a sound (step S24).

Here, the contents included in the web page are often viewed by users having specific attributes. Specifically, the content included in the web page is often viewed by users belonging to a specific age group. Therefore, according to these configurations, not only can the attributes such as the age group to which the user belongs be specified based on the contents of the parameters related to the contents of the web page, but also in an output mode suitable for the user having the specified attributes. You can reply the output web page. That is, for example, when the specified attribute is an attribute common to a person with weak visual acuity such as an elderly person, a web page that is output in a manner that can be easily viewed even by a user with low visual acuity can be returned. In addition, when the specified attribute is an attribute common to those who have less knowledge than elderly people such as young people, for example, a web page that is output in a manner that is easy to read even for users with little knowledge is returned. it can.

Further, according to these configurations, it is possible to specify the user attribute based on the action of the user who searches the web page. In other words, since the user's demographic information can be identified based on the user's behavior information, the user's demographic information is not directly acquired, but the user's behavior information is directly acquired. The web page output in an output mode suitable for the user can be returned.

In addition, although the terminal device 201 demonstrated as changing the output mode of a web page based on a style sheet, it is not necessarily limited to this. The terminal device 201 may change the output mode of the web page by executing a Java (registered trademark) program received from the web server device 100, for example.

<Modification 1 of Example 1>
In the present embodiment, the web server device 100 receives a web page generated by the web page generation unit 130 and a mode instruction for designating output of the web page in the output mode determined by the output mode determination unit 150. It has been described as a reply to the device 201. However, the present invention is not limited to this, and the web server device 100 outputs the output mode (for example, character size) of the web page generated by the web page generation unit 130 as determined by the output mode determination unit 150. The web page of the output mode converted into the mode may be returned to the terminal device 201.

<Modification 2 of Example 1>
In the present embodiment, the attribute specifying unit 140 uses, for example, attribute information representing the user's attribute as shown in FIG. 7A and a user having the attribute to search more than the user who does not have the attribute. In the above description, the attribute information associated with the keyword is retrieved from the table in which information associated with the information representing the search keyword is stored. In this table, words representing the same content are associated with information representing a search keyword used by a user having a certain attribute more frequently than a user who does not have that attribute and information representing the word. May be stored. Specific examples of such words include “chest” and “best”, which are words representing “short sleeveless sleeveless”. The term “chest” is mainly used for users who are “50 years old or older”, and the word “best” is mainly used for users who are “under 50 years old”. In this manner, the user's age group can be more accurately specified based on whether or not words having the same content but used at different frequencies depending on the user's age group are used as search keywords.

<Modification 3 of Example 1>
In the first embodiment, the output mode determination unit 150 stores information in which information indicating the user's age group and information indicating the output mode in the terminal device 201 used by the user are associated with each other in FIG. It has been described that an output mode suitable for the age group of the user specified by the attribute specifying unit 140 is determined using the table. Further, as shown in FIG. 7D, the output mode (output style) is described as including a mode of displaying characters of a web page at a predetermined size and a mode of displaying characters with or without ruby. did.

However, the present invention is not limited to this, and the output mode determination unit 150 stores information in which information representing the user's age group and information representing the user's gender are associated with information representing the output mode. A configuration in which an output mode is searched from the table based on the age group and sex of the user specified by the attribute specifying unit 140 can be adopted. The output mode (output style) may further include a mode of displaying a web page with a predetermined image as a background. As a specific example, a background image that is generally preferred by women aged 20 to 35 over homosexual users and male users of other age groups, such as a background image representing a flower such as a rose, This is a display mode as an image. According to these structures, a web page can be displayed in the aspect suitable for a different preference for every user's age group and sex.

In the present embodiment, the terminal device 201 has been described as adding a parameter to the URI and transmitting, and the server device 100 has acquired the parameter from the URI using, for example, a GET method. However, the present invention is not limited to this, and the terminal device 201 may transmit the URI without adding the parameter, and the server device 100 may acquire the parameter using, for example, the POST method.

Next, Example 2 will be described. The web server device 300 according to the second embodiment estimates a user's ability to use the terminal device based on a request received from the terminal device, and then outputs a web page according to the request and an output suitable for the user having the estimated ability. A mode instruction specifying that the web page is output in a mode is returned.

The web server device 300 according to the present embodiment, the communication network connected to the web server device 300, the terminal device that communicates with the web server device 300 via the communication network, the web server device 100 according to the first embodiment, the communication The description of the configuration common to the network 10 and the

terminal devices

201 and 202 is omitted.

The CPU included in the web server device 300 executes a request response process as illustrated in FIG. 9, thereby performing a parameter acquisition unit 320, a web page generation unit 330, an attribute identification unit 340, and a capability estimation unit 348 as illustrated in FIG. 10. , Function as an output mode determination unit 350, a search engine 355, and an advertisement information search unit 358. In addition, the CPU cooperates with the hard disk included in the web server device 300 to perform attribute database (hereinafter referred to as attribute DB) 341, capability database (hereinafter referred to as capability DB) 349, and mode database (hereinafter referred to as mode DB) 351. , And an advertisement database (hereinafter referred to as advertisement DB) 359. The reception unit 310 and the transmission unit 360 are the same as the reception unit 110 and the transmission unit 160 of the first embodiment.

When the execution of the request response process in FIG. 9 is started, the receiving unit 310 in FIG. 10 receives an HTTP request for requesting a reply to the web page from the terminal device (step S31). Next, the parameter acquisition unit 320 acquires parameters from the HTTP request received by the reception unit 310 (step S32). Thereafter, the attribute specifying unit 340 uses the attribute DB 341 that manages the information stored in the table of FIG. 7A and the information stored in the table of FIG. The attributes including the age group and gender of the user are specified by searching for (step S33).

Next, the capability estimation unit 348 executes capability estimation processing as shown in FIG. 11 for estimating the capability of the user (step S34). The user's ability includes the user's visual acuity, hearing ability, and intelligence. In addition, the user's ability may further include the user's academic ability, reading ability of documents, and understanding of the language used in the web page.

11 is started, the capability estimation unit 348 of FIG. 10 estimates the user's visual acuity based on the user's age group specified by the attribute specifying unit 340 (step S41). Specifically, the ability estimation unit 348 stores information that associates information representing an age group with information representing average visual acuity in the age group, information representing average hearing ability, and information representing average intelligence. The average visual acuity associated with the age group specified in step S33 of FIG. 9 is searched from the table managed in the capability DB 349. Thereafter, the ability estimation unit 348 estimates the retrieved average visual acuity as the visual acuity of the user.

In general, as the user ages, the user's visual acuity and hearing decrease, so the table used by the ability estimation unit 348 represents information indicating a high age group, information indicating a low visual acuity, and low hearing. It is associated with information. On the other hand, since knowledge accumulates in the user as the user ages, the table used by the ability estimation unit 348 is associated with information representing higher intelligence as information representing a higher age group. Yes.

After the process of step S41 of FIG. 11 is executed, the ability estimation unit 348 estimates the user's hearing based on the user's age group specified by the attribute specifying unit 340 (step S42). Next, the ability estimation unit 348 estimates the user's intelligence based on the identified age group of the user (step S43). Thereafter, the capability estimation unit 348 terminates the capability estimation process.

In addition, although the capability estimation part 348 demonstrated as estimating a user's capability based on a user's age, it is not necessarily limited to this. For example, when the search keyword is “steel frame” and “construction”, the attribute identification unit 140 identifies that the workplace, which is one of the user attributes, is “ironworks” or “construction site”. The estimation unit 348 can employ a configuration that estimates the user's hearing ability based on the attribute specified by the attribute specifying unit 140. Users who work at "Iron Works" or "Construction Site" are exposed to noise on a daily basis, so they are prone to occupational deafness and are accustomed to noise, so their ability to withstand low noise and high noise on average. It is because it can be estimated that it has. In addition, since there are occupations such as pilots that can only be engaged by people with good vision, piano tuners that can only engage those with good hearing, and teachers that can only engage those with high intelligence, the ability estimation unit 348 The user's ability may be estimated based on the occupation. Further, the web server device 300 may acquire the average intelligence of the user engaged in the occupation based on the user's occupation, and may estimate the acquired average intelligence as the user's intelligence. According to these structures, compared with the case where a user's ability is estimated based on an age group, a user's ability can be estimated more correctly separately.

When the process of step 34 in FIG. 9 is completed, the output mode determination unit 350 determines the output mode based on the user's capability estimated by the capability estimation unit 348 (hereinafter referred to as estimation capability), as shown in FIG. An output mode determination process is executed (step 35). The estimated ability includes the visual acuity estimated by the ability estimation unit 348 (hereinafter referred to as estimated visual acuity), the estimated hearing (hereinafter referred to as estimated hearing), and the estimated intelligence (hereinafter referred to as estimated intelligence).

12 is started, the output mode determination unit 350 determines the character size based on the estimated visual acuity (step S51). Specifically, the output mode determination unit 350 includes information representing the average visual acuity managed by the mode DB 351, information representing a character size suitable for a user having the visual acuity, and information representing a contrast suitable for the user. Is retrieved from a table that stores information associated with the character size associated with the information representing the estimated visual acuity. Similarly, the output mode determination unit 350 determines the contrast based on the estimated visual acuity (step S52).

Next, the output mode determination unit 350 determines the volume of sound output from the web page based on the estimated hearing (step S53). Specifically, the output mode determination unit 350 includes information representing the average hearing, information representing the volume suitable for the user having the hearing (that is, the volume that is easy to hear), and the frequency suitable for the user (that is, the listening). The information representing the volume associated with the information representing the estimated hearing ability is searched from the table managed in the mode DB 351 that stores the information associated with the information representing the easy frequency). Similarly, the output mode determination unit 350 determines a frequency based on the estimated hearing (step S54).

Next, the output mode determination unit 350 determines a ratio of using hiragana or katakana on the web page based on the estimated intelligence (hereinafter referred to as “kana usage rate”) (step S55). Specifically, the output mode determination unit 350 associates information representing the average intelligence with information representing a kana usage rate suitable for a user having the intelligence (that is, a kana usage rate that facilitates reading a web page). Information representing the kana usage rate associated with the information representing the estimated intelligence is retrieved from the table managed in the mode DB 351 that stores the information. The kana usage rate is, for example, the number of characters in hiragana or katakana with respect to the total number of characters used in the web page.

Next, the output mode determination unit 350 determines the number of images used in the web page (hereinafter referred to as the number of used images) based on the estimated intelligence (step S56). Specifically, the output mode determination unit 350 represents information representing the average intelligence and the number of images suitable for the user having the intelligence (that is, the number of images necessary to help the user understand the web page). Information representing the number of used images associated with the information representing the estimated intelligence is retrieved from the table managed in the mode DB 351 that stores the information associated with the information. Thereafter, the output mode determination unit 350 ends the execution of the output mode determination process.

After the execution of step S35 in FIG. 9 is completed, the search engine 355 in FIG. 10 searches the web page based on the parameters acquired by the parameter acquisition unit 320 (step S36). Specifically, as in the first embodiment, the web page analysis results collected by the bot program are searched based on the parameters.

Next, the advertisement information search unit 358 uses the output mode determination unit 350 to select products that are purchased more than other users by the user having the specified attribute based on the attribute specified by the attribute specifying unit 340. The advertisement to be advertised in the determined mode is searched (step S37). Specifically, the advertisement information search unit 358 represents the attribute specified by the attribute specifying unit 340 from a table managed in the advertisement DB 359 that stores information in which attribute information is associated with advertisement information representing an advertisement. Search for advertisement information associated with attribute information.

Here, the advertisement information includes information representing the URI of the advertisement image of the product, information representing the URI of the web page on which the advertisement text of the product is posted, and information representing the URI of the advertisement voice of the product. Next, the advertisement information search unit 358 searches the searched advertisement information for the advertisement information for advertising the product with the contrast advertisement image determined by the output mode determination unit 350 and the advertisement sound of the determined volume and frequency. To do. Further, the advertisement information search unit 358 publishes an advertisement that satisfies the kana usage rate determined by the output mode determination unit 350 from the searched advertisement information, and publishes an advertisement image of the determined number of used images. You may search the advertisement information showing the URI of a page.

After the process of step S <b> 37 is executed, the web page generation unit 330 is a web page representing the search result of the search engine 355 and the advertisement information searched by the advertisement information search unit 358, and the output mode determination unit 350. A web page having the output mode determined in (i.e., the determined mode) is generated (step S38).

Specifically, in the web page generation unit 330, the output mode determination unit 350 determines the contrast image determined by the output mode determination unit 350 from the images posted on the web page searched by the search engine 355. Search for the number of used images. Specifically, as illustrated in FIG. 13A, when the searched web page is a page on which an image RG11 and an explanatory text of “Blind Business Card Holder” are posted, The URI of the image RG11 representing the “blade card case” posted on the web page is acquired.

Further, the web page generation unit 330 uses, for example, a dictionary (that is, a library) in which kanji used in the search result of the web page searched by the search engine 355 is associated with kanji and kanji reading kana, An amount that satisfies the kana usage rate determined by the output mode determination unit 350 is converted into hiragana or katakana. Note that the web page generation unit 330 may generate a sentence in which a kana (ruby) is left in an amount that satisfies the determined kana usage rate. Further, the web page generation unit 330 may or may not change the character size of the web page according to the determination of the output mode determination unit 350. This is because the terminal device can change the character size of the web page according to the style sheet.

After that, the web page generation unit 330 includes a link AL1 to the web page on which the advertisement image AG1 and the advertisement text searched by the advertisement information search unit 358 as shown in FIG. The sentence RT1 representing the search result of the web page by the search engine 355 and the image RG11 posted on the searched web page at the kana usage rate determined in 350, and searched by the advertisement information search unit 358 A web page that outputs advertisement sound is generated.

Thereafter, the transmission unit 360 returns the generated web page and a mode instruction for designating output of the web page in the determined mode to the terminal device (step S39 in FIG. 9). Thereafter, the web server device 300 ends the execution of the reply request process.

Next, with reference to FIG. 13A, FIG. 13B, and FIG. 14, the web page output by the terminal device that has received the web page and the mode instruction from the web server device 300 will be described.

FIG. 13A is a diagram illustrating a web page P1 displayed by the terminal device when the user inputs the search keywords “boyfriend” and “present” to the terminal device. This user is a 20-year-old woman as in the first embodiment.

FIG. 13B shows a web page P2 displayed by the terminal device when the user inputs the search keywords “grandchild” and “present” to the terminal device. Note that this user is a 70-year-old male, as in the first embodiment.

FIG. 14 is a diagram showing a web page P3 displayed by the terminal device when the user inputs the search keywords “Grandpa” and “Present” to the terminal device. This user is an 8-year-old boy.

The character size of the web page P2 viewed by the 70-year-old user shown in FIG. 13B is larger than the character size of the web page P1 viewed by the 20-year-old user shown in FIG. Further, the advertisement image AG2 of the product posted on the web page P2 viewed by the 70-year-old user has a higher contrast than the advertisement image AG1 of the product posted on the web page P1 viewed by the 20-year-old user. Therefore, according to these configurations, for example, even a user with low vision due to his / her seniority can easily view a web page. Moreover, since it is easy for a user to visually recognize a web page, a product can be advertised efficiently.

Further, the character size of the web page P3 viewed by the 8-year-old user shown in FIG. 14 is larger than the character size of the web page P1 viewed by the 20-year-old user shown in FIG. Furthermore, the kana usage rate of the web page P3 viewed by the 8-year-old user is higher than the kana usage rate of the web page P1 viewed by the 20-year-old user (that is, hiragana or katakana is often used). Further, the web pages P1 and P3 display the texts RT1 and RT3 representing the web page search results and the images PG11 and PG31 and PG32 posted on the searched web page in association with each other. The number of images used on the web page P3 viewed by the 8-year-old user (that is, the number of used images) is the value “2”, and the value “1” of the number of used images of the web page P1 viewed by the 20-year-old user. It ’s more than Therefore, according to these configurations, since the web page is displayed in a mode in which the characters are large, the kana usage rate is high, and the number of used images is large, for example, because the age of completing compulsory education has not been reached, the intelligence (or Even users with low academic ability can easily read the contents of web pages.

Note that the advertisement sound output on the web page P2 viewed by the 70-year-old user has a louder volume and a higher frequency than the advertisement sound output on the web page P1 viewed by the 20-year-old user. According to these configurations, for example, even a user who has a low hearing ability due to his / her seniority can easily listen to the sound output on the web page. Moreover, since it is easy for the user to listen to the advertising sound, the product can be advertised efficiently.

In addition, the advertisement image AG1 posted on the web page P1 of FIG. 13A viewed by a 20-year-old user is usually purchased by a female user 20-34 years old more than other users. Is an image promoting " Similarly, the advertisement image AG2 posted on the web page P2 in FIG. 13B viewed by a 70-year-old user usually promotes “reading glasses” that a user 50 years or older purchases more than other users. It is an image to be. Similarly, the advertisement image AG3 posted on the web page P3 in FIG. 14 viewed by an 8-year-old user usually advertises “toys” that users 4 to 12 years old purchase more than other users. It is an image to be. Therefore, according to these structures, since the product advertised on the web page can be changed based on the user attribute specified by the web server device 300, the specific product can be efficiently advertised to the user.

In the present embodiment, the web server device 300 has been described as transmitting a web page on which an image with higher contrast is transmitted to the terminal device as the estimated visual acuity of the user is lower. However, the present invention is not limited to this, and the web server device 300 may transmit a web page on which a larger image is posted to the terminal device as the estimated visual acuity of the user is lower.

Note that the user of the terminal device browses the advertisement image AG1 (AG2 or AG3) displayed on the terminal device. In addition, when the user further displays and browses a web page on which a product advertised by the advertisement image AG1 (AG2 or AG3) is displayed on the terminal device, for example, by operating a mouse included in the terminal device, The cursor displayed on the terminal device is moved to the link AL1 (AL2 or AL3) and then the mouse is clicked. Thereafter, the terminal device downloads the web page that advertises the product designated by the user based on the signal input from the mouse according to the user's operation, and then the downloaded page is already displayed by the web server device 300. Display in the determined output mode. The downloaded page is not limited to a page for advertising a product, but may be a page used for purchasing a product.

<Modification 1 of Example 2>
In the present embodiment, the capability DB 349 of FIG. 10 stores information indicating an age group and information indicating an average intelligence of a general user belonging to the age group in association with each other. The average intelligence represented by the information stored in the ability DB 349 in association with the estimated age group of the user has been described as being estimated as the user's intelligence. However, the present invention is not limited to this. For example, the ability DB 349 of FIG. 10 inputs information representing hiragana each representing the same content, information representing katakana, information representing kanji, for example, information representing foreign language notation such as English, and the like to input the content in hiragana Information representing the average intelligence of a typical user, information representing the average intelligence of a general user who inputs the content in katakana, information representing the average intelligence of a general user who inputs the content in kanji, The ability estimation unit 348 stores the information in the ability DB 349 in association with hiragana, katakana, kanji, or foreign language parameters. It is possible to employ a configuration in which information representing the average intelligence obtained is searched and the average intelligence represented by the retrieved information is estimated as the user's intelligence.

In this configuration, the average intelligence represented by the information stored in the ability DB 349 is the average of general users who input the same contents in kanji rather than the average intelligence of general users who input the same contents in hiragana or katakana. The intelligence is set to a higher value. Similarly, in this configuration, the average intelligence represented by the information stored in the ability DB 349 is a general user who inputs the content in a foreign language rather than the average intelligence of a general user who inputs the same content in kanji. Although the average intelligence of is described as being set to a higher value, it is not limited to this. A more suitable average intelligence value can be determined experimentally by those skilled in the art.

Usually, even users who belong to the same age group have differences in reading and writing skills of Chinese characters and reading skills of foreign languages, so according to this configuration, when estimating the user's intelligence based on the user's age group The user's intelligence can be estimated more accurately than.

<Modification 2 of Example 2>
Next, an example of the request response process of FIG. 9 executed when the web server device 300 receives a request including a plurality of keywords “grandchild”, “boyfriend”, and “present” will be described.

The web server device 300 receives the parameters “grandchild”, “boyfriend”, and “present” that store a plurality of keywords input in the terminal device from the request received by executing step S31 of FIG. Obtain (step S32).

Here, the age group associated with the keyword “grandchild” in the tables of FIGS. 7A and 7B is “50 years or older”. On the other hand, the age group associated with the keyword “boyfriend” in the tables of FIGS. 7A and 7B is “13 to 19 years old” and “20 to 34 years old”. is there.

For this reason, since the age groups specified based on the respective keywords are in conflict, the attribute specifying unit 340 of the web server device 300 shown in FIG. 10 performs the keyword “grandchild”, A particle supplemented between “boyfriend” and “present” is estimated, and it is estimated that one sentence representing the search target of the user is “present for boyfriend of grandchild”. After that, the attribute specifying unit 340 uses the known analysis method executed based on the dependency relationship of the particles constituting the “present to the boyfriend of grandchild”, and includes the keywords “grandchild”, “boyfriend”, and “present”. Then, “grandchild” is selected as the keyword that best represents the user attribute. Next, the attribute identification unit 340 identifies the age group included in the user's attribute as “50 years or older” from the tables of FIG. 7A and FIG. 7B based on the selected keyword “grandchild”. (Step S33).

Thereafter, the web server device 300 uses the identified age group “50 years or older” to execute the processing from step S34 to step S39 in FIG. A web page output in an output mode suitable for a user belonging to an age group of “aged or older” is returned.

Here, the plurality of parameters often constitute a sentence representing the object to be searched by the user by adding a particle to each parameter. This tendency is particularly strong when the parameter is a search keyword. A plurality of parameters constituting one sentence represent other parameters and relationships with users by the dependency of particles. For this reason, according to these structures, a parameter can be selected based on the dependency relation of the particle supplemented between several parameters, and a user's attribute can be pinpointed accurately based on the selected parameter.

<Modification 3 of Example 2>
Next, an example of the request response process of FIG. 9 that is executed when the web server apparatus 300 receives a request including a plurality of keywords “boss”, “retirement allowance”, and “consultation” will be described.

As in the second modification of the second embodiment, the web server device 300 stores a plurality of keywords input from the terminal device from the request received in step S31 in FIG. “Boss” and “consultation” are acquired in the order of input (step S32).

Here, the attribute specifying unit 340 of the web server device 300 illustrated in FIG. 10 has the attribute “50 years old or older” associated with the keyword “retirement allowance” in the tables of FIG. 7A and FIG. "Male" or "female over 50" is specified as the attribute of the user. In contrast, the attribute specifying unit 340 associates the keywords “boss” with the attributes “female 20 to 34 years old” and “20” associated with each other in the tables of FIGS. 7A and 7B. The user's attribute is specified as “male from 34 years old”, “male from 35 years old to 49 years old”, or “male over 50 years old”. That is, some attributes specified based on each keyword overlap, but not all overlap.

For this reason, the attribute identification unit 340 weights the attributes associated with the previously input keyword more heavily, and then counts the number of times the attribute associated with the keyword is identified. Specifically, the attribute specifying unit 340 uses the weighting coefficient “1” for the number of times that the attributes “male over 50” and “female over 50” are identified based on the first input keyword. “1” times, but based on the keyword entered second, the attributes “female 20 to 34 years old”, “male 20 to 34 years old”, “male 35 to 49 years old” , And the number of times “male over 50” is counted as “0.5 times” multiplied by the weighting coefficient “1/2” instead of “1 time”. Thereafter, the attribute specifying unit 340 sets the total number of times of “0.5 times” for “female from 20 to 34”, “male from 20 to 34”, and “male from 35 to 49”. ”, The total specific number of weights of“ female over 50 ”is counted as“ 1.0 ”, and the total specific number of weights of“ male over 50 ”is“ 1.5 ” And count. Note that the total number of times of weight identification is also referred to as the degree of duplication because it represents the number of times the same attribute is identified in duplicate.

Thereafter, the attribute specifying unit 340 specifies that the user's attribute is “male over 50 years old” based on the most frequent total identification number. This is because users tend to input keywords that they think are important earlier, and keywords that users consider important are different when the user attributes are different, so the keywords entered earlier are closer to the user attributes. Because it is considered to be related to For this reason, the weighting coefficient is also referred to as importance. As a specific example, a user in the age group of “20 to 34 years” has a shorter service period than a user in the age group of “50 years and older” and pays less retirement money at the time of retirement. There is a strong tendency not to think that the keyword is important. Therefore, a user who inputs the keyword “retirement allowance” before other keywords is likely to be a user in the age group of “50 years or older”.

When the user attribute is specified as “male over 50 years old”, the web server apparatus 300 executes the request response process after executing the process from step S34 to step S39 in FIG. 9 using the specified attribute. By ending, the web page output in the output mode suitable for the user having the attribute of “male over 50” is returned.

Here, the keywords used for the search as described above are input in order from the keywords that the user considers important. Normally, the parameters in the request are arranged in order according to the order in which the keywords stored in the parameters are input. For this reason, according to these structures, a user's attribute can be pinpointed with sufficient accuracy based on a plurality of parameters and an order in a request of these plurality of parameters.

Ordinarily, when a plurality of user attributes are specified by each keyword, it is considered that the attribute specified more redundantly represents the user attribute more accurately than the attribute not specified so. For this reason, according to these structures, a user's attribute can be pinpointed accurately based on the importance of the attribute specified by each of a plurality of parameters.

<Modification 4 of Example 2>
In the present embodiment, the attribute DB 341 of the web server device 300 illustrated in FIG. 10 includes information representing an attribute, type information representing a type of web browser that a user of the attribute uses more than a user of another attribute, Can be employed in association with each other. As a specific example, a web browser of the type “Chrome (registered trademark)” has a relatively short history and is not a browser installed by default on personal computers, so it has a wealth of computer knowledge and is a new one. It is mainly used by users who are sensitive to the attribute “male between the ages of 20 and 34”. On the other hand, since the browser of the type “bing (registered trademark)” of MSN (MicroSoft Network) (registered trademark) is installed by default in a personal computer, the knowledge of the computer is not abundant, and it is a new one. It is mainly used by users who are "50 years old or older" who are not sensitive. In this configuration, the parameter acquisition unit 320 acquires type information representing the type of web browser used by the user in the terminal device from the header portion of the request received by the reception unit 310, and the attribute identification unit 340 is acquired. A configuration can be adopted in which the attribute represented by the attribute information associated with the type information is specified as a user attribute. According to this configuration, the user's attribute can be accurately identified based on the type of browser used by the user.

<Modification 5 of Example 2>
In the present embodiment, the attribute DB 341 can employ a configuration in which information representing an attribute and type information representing a type of terminal device used by a user with the attribute more frequently than a user with another attribute are stored in association with each other. . As a specific example, a model such as a smartphone is mainly used by users having an attribute of “male from 20 to 34 years old” or “female from 20 to 34 years old”. In this configuration, the parameter acquisition unit 320 acquires type information indicating the type of terminal device used by the user by acquiring, for example, “HTTP_USER_AGENT” information from the header part of the HTTP request received by the reception unit 310. And the attribute specific | specification part 340 can employ | adopt the structure which specifies the attribute represented by the attribute information matched with the acquired kind information as a user's attribute. According to this structure, a user's attribute can be pinpointed accurately based on the kind of terminal device which a user uses.

<Modification 6 of Example 2>
In the present embodiment, the attribute DB 341 stores information representing an attribute in association with time zone information representing a time zone in which a user with the attribute browses a website more than a user with another attribute. Can be adopted. As a specific example, a user who is “50 years or older” has a strong tendency to browse web pages in the early morning hours from 5 am to 7 am, for example. On the other hand, users who are “20 to 34 years old” have a strong tendency to browse web pages in the late-night time zone from 10:00 to 12:00, for example. In this configuration, when receiving the request, the receiving unit 310 refers to, for example, the OS (Operating System) system time, sets the referred system time as the request receiving time, and the parameter acquiring unit 320 receives the request. Is acquired from the receiving unit 310, and the attribute specifying unit 340 searches the attribute information associated with the time zone information indicating the time zone to which the acquired reception time belongs, and determines the attribute represented by the searched attribute information. It is possible to adopt a configuration that identifies the attribute of the user. According to this configuration, the user attribute can be accurately identified based on the time when the request is received.

<Modification 7 of Example 2>
In this embodiment, the attribute DB 341 can employ a configuration in which information representing an attribute and a search condition symbol representing a search condition expression used by a user of the attribute more frequently than a user of another attribute are stored in association with each other. . As a specific example of the search condition symbol, the symbol “OR” and the keyword 1 of the search condition expression “keyword 1 OR keyword 2” for searching for a web page in which the keyword 1 or the keyword 2 is described are described. Search for a web page using the search condition expression “keyword 1 -keyword 2” symbol “-” and “keyword 1 keyword 2” as one search keyword to search for a web page in which keyword 2 is not described A search condition expression "" keyword 1 keyword 2 "" symbol """is obtained. The search condition formulas represented by these search condition symbols are often used by users of a young age group “20 to 34 years old” who are familiar with the usage of the search engine compared to other age groups. In this configuration, the parameter acquisition unit 320 acquires a search condition expression using parameters from the request received by the reception unit 310, acquires a search condition symbol as a parameter from the acquired search condition expression, and the attribute specification unit 340 A configuration can be adopted in which the attribute represented by the attribute information associated with the acquired search condition symbol is specified as the user attribute. According to this configuration, the user attribute can be accurately identified based on the search condition formula style used by the user.

Next, Example 3 will be described. As illustrated in FIG. 15, the web server device 400 according to the third embodiment of the present invention connects to the search server 500 as well as the

terminal devices

203 and 204 via the communication network 10 described in the first embodiment, for example. . Since the

terminal devices

203 and 204 have the same configuration, the description of the terminal device 204 is omitted.

As described in the first embodiment, the terminal device 203 accepts a search keyword input by a user operation. For example, the terminal device 203 receives search keywords input to the terminal device 203 such as “grandchild” and “present”. Next, the terminal device 203 stores the search keyword in the parameter and generates an HTTP request. Thereafter, the terminal device 203 adds a parameter to the URI included in the HTTP request according to a predetermined rule. Next, the terminal device 203 transmits an HTTP request including a parameter in the URI to the search server device 500.

The search server device 500 receives an HTTP request from the terminal device 203. Next, the search server device 500 acquires a URI from the received HTTP request, and then acquires a parameter storing character strings “grandchild” and “present” added to the end of the URI.

Next, the search server device 500 generates a web page representing a search result obtained by searching the web page on the communication network 10 based on the acquired parameter, and transmits the web page to the terminal device 203. At this time, the URI of the web page indicating the search result includes parameters (in this example, “grandchild” and “present”).

The terminal device 203 receives the web page indicating the search result from the search server device 500, and displays the web page on the LCD. Next, the terminal device 203 receives the URI clicked by the user's operation (in this example, the URI of the web server device 400) in a state where the web page indicating the search result is displayed on the LCD. Next, the terminal device 203 generates an HTTP request that stores the clicked URI. Thereafter, the terminal device 203 transmits an HTTP request to the web server device 400. At this time, a URI including parameters (in this example, “grandchild” and “present”) is also transmitted as a referrer indicating the web page of the link source (that is, the reference source).

The web server device 400 responds to the HTTP request transmitted by the terminal device 203 by executing a request response process as shown in FIG.
When the execution of the request response process shown in FIG. 16 is started, the web server device 400 receives an HTTP request from the terminal device 203 (step S71). Next, the web server device 400 acquires a parameter storing character strings “grandchild” and “present” added to the end of the URI as the referrer from the received HTTP request (step S72).

Next, the web server device 400 acquires the web page indicated by the URI (that is, the web page requested by the HTTP request) from, for example, the hard disk included in the web server device 400 (step S73). Thereafter, the web server device 400 specifies the user attribute using the acquired parameters (step S74). Here, the attributes include, for example, the user's age group and gender. For example, the web server device 400 refers to the table shown in FIG. 7A and FIG. 7B from the character string “grandchild” of the parameter, and the user's age group is “50 years or older”. Identify that there is.

After step S74 of FIG. 16 is executed, the web server device 400 executes an output mode determination process for determining an output mode in the terminal device 203 of the acquired web page based on the identified user attribute ( Step S75). For example, when the user's age group is “50 years or older”, referring to the tables shown in FIGS. 7C and 7D described above, the character size is “18” points and the ruby is “none”. The output mode in the terminal device 203 is determined as the display mode for displaying the web page.

After step S75 is executed, the web server device 400 returns the acquired web page and a mode instruction for designating output of the web page in the determined output mode to the terminal device 203 (step S76). .

Upon receiving the web page and the mode instruction, the terminal device 203 displays the web page in the mode specified by the mode instruction by executing the page output process as shown in FIG.

In the present embodiment, the web server device 400 returns to the terminal device 203 a web page acquired from the hard disk of the web server device 400 and a mode instruction for designating output of the web page in the determined output mode. As explained. However, the present invention is not limited to this, and the web server device 400 converts the output mode (for example, character size) of the acquired web page into the determined output mode, and the converted web page of the output mode. May be returned to the terminal device 203.

According to these configurations, for example, without acquiring the behavior information of the user such as searching for a web page, based on the parameters used for searching the web page that is the reference source of the website for which a reply is requested, Since the demographic information of the user can be specified, a web page output in an output mode suitable for the user can be returned.
