Description

  The present invention relates to a sentence value evaluation method, a sentence value evaluation system, and a sentence value evaluation program, and more particularly to a method for evaluating the value of a sentence as electronic data created by using a computer. The present invention is particularly suitable for evaluating the advertising value of a blog published via the Internet.

  In recent years, advertisement using the Internet (Internet advertisement) has been performed. For example, when a viewer accesses a website via the Internet and browses a page of the site, an advertisement of a company or the like is displayed on a predetermined portion of the browse page, for example, a surrounding portion.

  In many cases, the display space for the advertisement is lent to an advertiser such as a company as an advertising space by a website operator. Thereby, the website operator can collect the lending cost of the advertising space from the advertiser as the advertising cost. A typical example of such a website is called a portal site (entrance site).

  By borrowing the advertising space of the portal site, the advertiser can easily provide its own advertisements to many viewers without operating and managing its own website (own site). Even if the company site is operated and managed, the company advertisement can be provided to more viewers by displaying the company advertisement on the portal site. Accordingly, it is possible to obtain a high advertising effect without having to induce many viewers to the site.

  In addition, by clicking on the advertisement on the portal site, more detailed advertisement information can be provided to further improve the advertising effect on the viewer, or the portal site can be linked to the company site. By doing so, the viewer can be easily guided to the company site.

  In such a portal site, various information attracting the interest of the viewer is provided, and the number of viewers of the popular portal site is enormous. In general, a large number of viewers means that the advertising effect is high, and a highly popular portal site can collect a high advertising cost from an advertiser. As mentioned above, advertising space may be provided around the browsing page of the portal site, but when the viewer accesses the portal site, an advertising window separate from the browsing page automatically pops up, An advertisement space may be provided in the advertisement window.

  On the other hand, recently, many websites called blogs (web logs) have been established. The blog is created on the blog server by the founder, and includes a diary-like sentence, an image such as a photo, and various other information. The blog server is connected to the Internet, and the contents of the blog are published via the Internet. Therefore, it is possible for others to easily read a blog, create a comment, and perform a trackback via the Internet. Such blogs are rapidly spreading because they are easy to open and manage.

Note that there is an Internet advertisement disclosed in Patent Document 1 and a blog disclosed in Patent Document 2.

  With the rapid spread of such blogs, the number of blog viewers is increasing year by year compared to the number of portal site viewers. Therefore, if the company advertisement can be displayed in association with the blog, the advertiser can expect a great advertising effect. For example, if a phrase in a blog and an advertisement are associated with an advertisement, and the company advertisement is displayed when the phrase is clicked, the advertiser expects a very large advertising effect. Can do.

  However, unlike portal site operators, blog publishers are generally those who do not have expertise in computers or networks. There is a problem that it is very difficult for such a blog creator to perform a process of associating an advertiser's advertisement with his / her blog.

  If the process of associating the words in the blog with the advertisement is automatically performed, it is desirable that the process related to the advertisement display can be reduced. Also, if the blog value is evaluated based on the words in the blog, and if the blog creator is given any benefit according to the evaluation value, the establishment of a new blog or update of the blog will be promoted, and eventually the advertiser It is very desirable to expect improved advertising effectiveness. Furthermore, if a phrase in a blog is associated with a search keyword as well as an advertisement, a viewer can obtain various information about the phrase simply by clicking on the phrase, and can receive advertisements related to the phrase. This is a great advantage for viewers and advertisers.

  The present invention has been made in view of the above circumstances, and provides a sentence value evaluation method, a sentence value evaluation system, and a sentence value evaluation program capable of evaluating the value of a sentence based on words in the sentence. Let it be an exemplary problem. In addition, it automatically associates advertisement information and search keywords based on the words in the text, and is useful for text writers, advertisers, and text viewers. Providing the above is another exemplary problem.

  The sentence value evaluation method as an exemplary aspect of the present invention determines whether or not each phrase in a phrase database including a plurality of phrases associated with a predetermined value index value is included in the sentence. A step of detecting, and a step of adding value index values associated with each word detected in the sentence.

  Since the sentence value is evaluated based on a phrase database configured by having a plurality of phrases associated with a predetermined value index value, the value of the sentence can be quantitatively evaluated. The value index value may be, for example, some point or a monetary value (amount).

  When the value index value is a monetary value, when 20 words / phrases corresponding to 5 yen are detected in a certain sentence, the monetary value of the sentence becomes 100 yen, and a word / phrase corresponding to 8 yen is found in other sentences. When one is detected, the monetary value of the sentence is 160 yen. Since the value is evaluated for each sentence and the sentences are ranked based on the value, the sentence creator tries to create a sentence of higher value by competitiveness. In this way, creation of a sentence having high value can be promoted. If a privilege is given to the text creator based on the text value (such as monetary value or points), the text creation can be further promoted.

  For example, if each phrase in the phrase database has an advertising effect, and a value index value is associated with each phrase according to the degree of its effectiveness, high-value sentences will exhibit a high advertising effect. It becomes. In other words, this sentence value evaluation method enables the creator of a sentence to promote the creation of a high-value sentence by granting a privilege based on the sentence value, and the accompanying advertisement effect can be improved.

  In the above sentence value evaluation method, a sentence is composed of text data, a phrase database is held in a storage device, and a step of detecting and summing up sentences input via the Internet, and via the Internet And outputting the total value to the outside.

  Each step of inputting the sentence, detecting a phrase in the sentence, adding the value index values, and outputting the added value externally is performed by one or a plurality of computers. Since the computer detects the words and adds the value index values, the operations can be performed easily, quickly, and accurately.

  For example, in a configuration in which sentences are described in a blog stored in a blog server, a storage device is a hard disk, and a computer having the hard disk and a web server are connected via the Internet, the blog server It is also possible that the computer automatically detects words / phrases in sentences input to the computer, adds the value index values, and outputs the combined values. As a result, the sentence value evaluation can be performed easily, quickly and accurately, so that it is possible to further promote the creation of a high-value sentence and to improve the advertising effect associated therewith.

  Further, the method includes a step of executing hyperlink processing for each word detected in the sentence, and a step of outputting a sentence including each word subjected to the hyperlink processing to the outside via the Internet. Also good.

  When a sentence in a blog includes a phrase that has an advertising effect, the advertising effect on the blog viewer is exhibited even if the blog is only published on the Internet. However, when a hyperlink process is performed on the phrase, it is possible to provide various additional values to the sentence.

  For example, if you click on a phrase, advertisement information related to the advertising effectiveness of that phrase is displayed, or if the advertiser's site that provides the advertisement information (your company site) is displayed, further advertisements The effect can be improved. In addition, if a keyword search result using the phrase as a search keyword is displayed when the phrase is clicked, it is very convenient for the viewer.

  In this way, if the computer is configured to automatically perform hyperlink processing to words in a sentence and external output of the sentence after execution, various types of sentences can be easily, quickly and accurately performed. It can provide added value. Therefore, it is possible to further promote the creation of high-value text, and to improve the advertising effect associated therewith.

  A sentence value evaluation system as another exemplary aspect of the present invention includes a phrase database configured to include a plurality of phrases associated with a predetermined value index value, a storage device that holds the phrase database, And whether or not each phrase in the phrase database is included, and the value index value associated with each phrase detected in the sentence is added together, and the hypertext is detected for each phrase detected in the sentence. And a computer that executes link processing.

  Since the sentence value is evaluated based on a phrase database configured by having a plurality of phrases associated with a predetermined value index value, the value of the sentence can be quantitatively evaluated. The value index value may be, for example, some point or a monetary value.

  When the value index value is a monetary value, when 20 words / phrases corresponding to 5 yen are detected in a certain sentence, the monetary value of the sentence becomes 100 yen, and a word / phrase corresponding to 8 yen is found in other sentences. When one is detected, the monetary value of the sentence is 160 yen. Since the value is evaluated for each sentence and the sentences are ranked based on the value, the sentence creator tries to create a sentence with higher value from a competitive spirit. In this way, creation of a sentence having high value can be promoted. If a privilege is given to the text creator based on the text value (such as monetary value or points), the text creation can be further promoted.

  For example, if each phrase in the phrase database has an advertising effect, and a value index value is associated with each phrase according to the degree of the effect, the high-value sentence will exhibit a high advertising effect. It becomes. In other words, this sentence value evaluation system enables the creator of a sentence to promote the creation of a high-value sentence by granting a privilege based on the sentence value, and the accompanying advertising effect can be improved.

  The steps of detecting a phrase in the sentence, summing the value index values, and hyperlinking processing for the phrase are all automatically performed by one or a plurality of computers. Since the computer detects the phrase and adds the value index values, it is possible to easily, quickly and accurately evaluate the value of the text in the blog.

  It is possible to provide various added values to the sentence by the hyperlink processing for the phrase. For example, if you click on a phrase, advertisement information related to the advertising effectiveness of that phrase is displayed, or if the advertiser's site that provides the advertisement information (your company site) is displayed, further advertisements The effect can be improved. In addition, if a keyword search result using the phrase as a search keyword is displayed when the phrase is clicked, it is very convenient for the viewer. As described above, since the hyperlink processing to the words in the sentence is automatically performed by the computer, various added values can be provided to the sentence easily, quickly and accurately.

  According to still another exemplary aspect of the present invention, a sentence value evaluation program includes a computer and each phrase in a phrase database configured to include a plurality of phrases associated with a predetermined value index value. Means for detecting whether or not a word is detected, means for summing value index values associated with each word detected in the sentence, and means for executing hyperlink processing for each word detected in the sentence It is characterized by functioning as.

  Since the sentence value is evaluated based on a phrase database configured by having a plurality of phrases associated with a predetermined value index value, the value of the sentence can be quantitatively evaluated. The value index value may be, for example, some point or a monetary value.

  When the value index value is a monetary value, when 20 words / phrases corresponding to 5 yen are detected in a certain sentence, the monetary value of the sentence becomes 100 yen, and a word / phrase corresponding to 8 yen is found in other sentences. When one is detected, the monetary value of the sentence is 160 yen. Since the value is evaluated for each sentence and the sentences are ranked based on the value, the sentence creator tries to create a sentence with higher value from a competitive spirit. In this way, creation of a sentence having high value can be promoted. If a privilege is given to the text creator based on the text value (such as monetary value or points), the text creation can be further promoted.

  For example, if each phrase in the phrase database has an advertising effect, and a value index value is associated with each phrase according to the degree of its effectiveness, high-value sentences will exhibit a high advertising effect. It becomes. In other words, this sentence value evaluation program enables the creator of a sentence to promote the creation of a high-value sentence by granting a privilege based on the sentence value, and the accompanying advertising effect can be improved.

  Each step of detecting a phrase in a sentence, summing a value index value, and hyperlink processing for the phrase is performed by one or more computers functioning as a phrase detection means, a value index value summing means, and a hyperlink processing execution means. Done automatically. Since the computer detects the phrase and adds the value index values, it is possible to easily, quickly and accurately evaluate the value of the text in the blog.

Therefore, it is possible to promote the creation of a sentence having high value, and it is possible to improve the advertising effect associated therewith. The computer can detect words and phrases in sentences, add together the value index values associated with the detected words, and perform hyperlink processing for the words, and so on, so that the value of the sentences can be evaluated easily, quickly, and accurately. Additional value (for example, display of advertisement information, improvement of keyword search convenience, etc.) can be provided.

[Embodiment]
Hereinafter, an internet advertising system using a text value evaluation method according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram showing the overall configuration of the Internet advertising system S. The Internet advertising system S is roughly configured to include a blog server 2, an opening computer 4, a browsing computer 6, a sentence value evaluation system 8, a company server 10a of an advertiser 10 and a portal server 12. They are connected to each other via W.

  The blog server 2 is a server computer that stores, holds, and publishes a blog 14 as a sentence configured using text data. A configuration example of the blog 14 is shown in FIG. The blog 14 includes a diary-like sentence 16 created by the founder. The image 14e may be posted together with the comment 14b, trackback 14c, update history 14d, etc. for the sentence. The blog server 2 has a function of transmitting the text 16 in the blog 14 to the text value evaluation system 8 based on a request from the text value evaluation system 8 described later.

  The establishment computer 4 is a computer that is operated by the establishment person of the blog 14. Sentence 16 created by the establishment person using this establishment computer 4 is transmitted to the blog server 2 via the Internet W, and is published as the sentence 16 in the blog 14. Accordingly, the establishment computer 4 has text editing software for editing the text 16 and communication software for transmitting the text 16 to the blog server 2. The established computer 4 can also transmit the prepared sentence 16 to the sentence value evaluation system 8 based on a request from the sentence value evaluation system 8 described later.

  The browsing computer 6 is a computer that is operated by a viewer who browses the blog 14 via the Internet W, and includes a display unit 6a. The viewer operates the browsing computer 6 to access the blog server 2 via the Internet W to browse the text 16 of the blog 14, or accesses the portal server 12 to browse the portal site browsing page 12 b (FIG. 5). Browse). Therefore, the browsing computer 6 has communication software for connecting to the Internet W and a browser (viewing software) for browsing pages of various websites. Note that a normal personal computer having sentence editing software, communication software, a browser, and the like can be applied to the establishment computer 4 and the browsing computer 6.

  As shown in FIG. 3, the sentence value evaluation system 8 includes an evaluation computer 18. The evaluation computer 18 can be connected to the blog server 2 and the established computer 4 via the Internet W, and has a CPU (main part of the computer) 18a as information processing means and a hard disk 18b as a storage device. And a memory 18c.

  The evaluation computer 18 has a function of transmitting an input request signal for requesting input of the text 16 to the blog server 2 or the established computer 4. This input request signal is transmitted when the blog 14 is opened and a new sentence 16 is created or when the sentence 16 in the blog 14 is updated. When the request signal is received, the sentence 16 is transmitted from the blog server 2 or the established computer 4 to the evaluation computer 18.

  The hard disk 18b holds a sentence value evaluation program P and a phrase database D. The sentence value evaluation program P is for causing the evaluation computer 18 to function as a phrase detection unit, a summation unit (value index value addition unit), and a hyperlink process execution unit.

  The phrase detection means detects whether or not a phrase constituting the phrase database D is included in the sentence 16 input from the blog server 2 or the opening computer 4. An outline of the internal configuration of the phrase database D is shown in FIG. The phrase database D includes a plurality of phrases, and each phrase is associated with a predetermined amount (value index value) and link destination information.

  In the present embodiment, the phrase “restaurant” W1 is associated with an amount (value index value) V1 of 5 yen, and the phrase “mobile phone” W2 is associated with an amount (value index value) V2 of 10 yen, The phrase “network” is associated with an amount (value index value) V3 of 7 yen. The amounts of money V1 to V3 corresponding to each of these words / phrases W1 to W3 are determined based on the advertising effect of each word / phrase.

  For example, a company (advertiser) 10 that conducts a restaurant-related business determines that there is an advertising effect equivalent to an amount V1 of 5 yen for the phrase “restaurant” W1, and bears a predetermined advertising cost. Then, when the phrase “restaurant” W1 is included in the sentence 16 of the blog 14, an amount V1 of 5 yen as a consideration is paid to the founder of the blog 14, and the “restaurant” The advertisement information of the company 10 is displayed on the display unit 6a of the browsing computer 6 when the word W1 is clicked by the viewer.

  For example, when the word / phrase W1 in the sentence 16 is clicked, the browsing page 12b (see FIG. 5) of the portal site of the portal server 12 that provides the keyword search service may be displayed. If the keyword search result 12c performed using the word / phrase W1 as a keyword and the advertisement information 12d of the company 10 are already displayed in the browsing page 12b, it is convenient for the viewer and the advertising effect is improved. Of course, when the word / phrase W1 in the sentence 16 is clicked, the browsing computer 6 may be configured to access the company site in the company server 10a.

  Similarly, for the other words / phrases W2 / W3 in the word / phrase database D, when each word / phrase W2, W3 is included in the sentence 16 of the blog 14, the amount of money as a consideration for the founder of the blog 14 V2 and V3 are paid, and when each word / phrase W2 / W3 in the sentence 16 is clicked, advertisement information of each advertiser for each word / phrase W2 / W3 is displayed.

  The phrase detection means compares and determines the phrase in the sentence 16 and the plurality of phrases W1 to W3 in the phrase database D, and detects how many phrases in the phrase database D are included in the sentence 16. . The detection result is sent to the amount summation unit and the hyperlink processing execution unit.

  The amount summing unit calculates the amount of the sentence 16 based on the detection result sent from the phrase detection unit. That is, the total sum of the products of the number of each phrase included in the sentence 16 and the amount associated with the phrase is calculated. The calculated total amount (sentence value) is transmitted to the blog server 2 or the established computer 4 via the Internet W.

  The hyperlink processing execution means automatically performs hyperlink processing for each of the words W1 to W3 detected in the sentence 16 based on the detection result sent from the word detection means. FIG. 2B shows the blog 14 in which hyperlink processing has been performed on the words W1 to W3 in the sentence 16. The hyperlink process for each word / phrase W1 to W3 is executed based on link destination information L1 to L3 associated with each word / phrase W1 to W3. Therefore, for example, when the word / phrase W1 is clicked, the browsing computer 6 displays the link destination information indicated by the link destination information L1 on the display unit 6a. The link destination information includes advertisement information of the company 10, a portal site of the portal server 12, a company site in the company server 10a of the company 10, and the like. The sentence (processed sentence) 16a on which the hyperlink process for each of the words W1 to W3 has been executed is transmitted to the blog server 2 via the Internet W.

  The in-house server 10a is a server computer that is operated and managed by the company 10 as an advertiser. A company site is built in the company server 10a, and information relating to advertisements and advertisements of the company 10 is posted so as to be viewable via the Internet W.

  A portal site is constructed in the portal server 12, and various information, advertisements, and the like are posted on the browsing page 12b. The portal server 12 has a keyword search engine, and a keyword search service is provided on the portal site. When a keyword is entered in the portal site browsing page 12b and a search is started, various information and websites related to the keyword are browsed based on a predetermined ranking (in order of hit rate, order of update date, etc.). 12b is displayed. At that time, advertisement information related to the keyword is also displayed on the browsing page 12b.

  When the word W1 in the sentence 16 of the blog 14 is clicked and the browse page 12b is displayed based on the link destination information L1 associated with the word W1, the keyword search result 12c that already uses the words W1 to W3 as keywords. The browsing page 12b is displayed in a state where the advertisement information 12d is displayed. Of course, the same applies to the words W2 and W3.

  Next, the sentence value evaluation method by the sentence value evaluation system 8 in the Internet advertising system S will be described with reference to the flowchart of FIG.

  The creator of the blog 14 creates a sentence 16 on the opening computer 4 and transmits the sentence 16 to the evaluation computer 18 of the sentence value evaluation system 8 via the Internet W (S.1). When the sentence 16 is input, the evaluation computer 18 that functions as the phrase detection means by the sentence value evaluation program P determines whether the input sentence 16 includes the words W1 to W3 in the phrase database D. Is detected (S.2).

  When the words W1 to W3 are detected in the sentence 16, the evaluation computer 18 that functions as the amount summing means by the sentence value evaluation program P uses the amounts V1 to V3 associated with the detected words W1 to W3. Summing up and calculating the sentence amount (sentence value) (S.3). That is, the product of the number of detected phrases and the amount associated with the phrase is obtained for each of the phrases W1 to W3, and the sum of these integrated values is calculated to obtain the sentence amount. The text amount is transmitted to the opening computer 4 via the Internet W (S.4). The establishment person of the blog 14 is given a privilege according to the sentence value.

  On the other hand, the evaluation computer 18 that is caused to function as the hyperlink processing execution means by the sentence value evaluation program P executes the hyperlink process for each word / phrase W1 to W3 detected in the sentence 16 to obtain the processed sentence 16a. Create (S.5). The link destinations when the words W1 to W3 are clicked are based on the link destination information L1 to L3 associated with the words W1 to W3 in the word database D.

  The processed sentence 16a is transmitted from the sentence value evaluation system 8 to the blog server 2 via the Internet W (S.6). When the processed text 16a is received, the blog server 2 posts the processed text 16a in the blog 14 and publishes it via the Internet W (S.7).

  When the browsing person browses the blog 14 by the browsing computer 6, the processed sentence 16a is displayed on the display unit 6a. Each of the words W1 to W3 in the post-processing sentence 16a is subjected to hyperlink processing. When the viewer clicks on the word / phrase W1 in the processed sentence 16a, the advertisement information of the company 10 is displayed on the display unit 6a based on the link destination information L1 of the word / phrase W1.

  When the link destination information L1 indicates the own server 10a of the company 10, the page of the company 10's own site is displayed on the display unit 6a. Further, when the link destination information L1 indicates the portal server 12, the portal site browsing page 12b including the keyword search result 12c using the word W1 as a keyword and the advertisement information 12d of the company 10 is displayed on the display unit 6a.

  In the above description, the sentence 16 is input from the establishment computer 4 to the sentence value evaluation system 8, but of course, the sentence 16 may be input from the blog server 2 to the sentence value evaluation system 8. Further, although the processed text 16a is output from the text value evaluation system 8 to the blog server 2, the processed text 16a may of course be output from the text value evaluation system 8 to the establishment computer 4. The text amount may also be transmitted to one or both of the opening computer 4 and the blog server 2. These are all appropriately selected according to the convenience of system design.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation and change are possible within the range of the summary.
