In the following description, the functions of the terminal 1 are denoted by the same reference numerals, and the functions of the server 2 are described by adding the dashes to the reference numerals of the functions of the terminal 1 shown in FIG. 2 (for example, the display unit 18 ').

FIG. 3 is a functional block diagram when the information processing program is started in the terminal 1. The access processing unit 41 controls data exchange with the server 2 via the Internet 3. When using the service of the bulletin board provided in the server 2, the text processing unit 42
A process related to text data (text data input by the user) to be written on the bulletin board is performed. The display control unit 43 performs control when displaying image data, text data, and the like acquired by exchanging data with the server 2 on the display unit 18.

FIG. 4 is a functional block diagram when the information presentation program is started in the server 2. The access processing unit 51 controls data exchange performed between the terminal 1 and the Internet 3. Specifically, data from the terminal 1 is output to one of the bulletin board data acquisition unit 52, the search unit 56, the advertisement database creation unit 57, and the billing database creation unit 58, and is supplied from the search unit 56. The data is transmitted to the terminal 1.

The bulletin board data acquiring section 52 acquires text data written on the bulletin board, and outputs the document attribute processing section 53
And to the document content processing unit 54. The document attribute processing unit 53 extracts the attribute information of the document supplied from the bulletin board data acquisition unit 52, groups the documents based on the attribute information, and supplies the documents to the document content processing unit 54 and the user-specific database creating unit 55. . As the attribute information of the document, for example, a message ID for identifying the target text data, a transmission source, a date of writing, and the like are extracted.

The document content processing section 54 includes a document attribute processing section 5
The texts of the documents grouped in step 3 are extracted, subjected to morphological analysis and divided into keywords (words), and the appearance frequency of the keywords and the distribution status over a plurality of documents are obtained. (A value indicating a degree related to the gist of the document). In the calculation of the weight, for example, tf
・ Idf method (Salton, G .: Automatic Text Processing: The Tra
nsformation, Analysis, and Retrieval of Information
by Computer, Addison-Wesley, 1989). However, words distributed over a wide range, that is, words such as “Thank you” and “Please,” which are included in almost all documents, are excluded because they cannot be keywords. In the present embodiment, it is assumed that only nouns are treated as keywords.

The user-specific database creation unit 55 creates a database of attribute information of each document and the weight of all keywords included in the document for each document grouped by the document attribute processing unit 53, and sends the database to a hard disk drive or the like. In the storage unit 19 ′. FIG. 5 shows an example of the user-specific database created and stored by the user-specific database creating unit 55. As shown in FIG. 5, the database creating unit 55 for each user includes items such as “user ID”, “access date and time”, “bulletin board NO (number)”, “word and frequency”, and “presented advertisement and operation”. Is provided to create a database in which the data of each item is associated with each other.

In the item "user ID", for example, when the user desires to use the bulletin board, the user registers and the ID given at the time of the registration is stored. The item “access date and time” stores the date and time when the bulletin board was accessed. In the item “bulletin board NO”, a number assigned so that the bulletin board is uniquely distinguished is stored. The item “word and frequency” stores the word extracted by the processing of the sentence content processing unit 54 and the number of times the word is used in association with each other. In the item “presentation advertisement and operation”, based on the information stored for each item described above, the advertisement number of the advertisement presented to the user and the processing performed by the user on the presented advertisement (access Are stored in association with each other.

The search unit 56 searches the advertisement database created by the advertisement database creation unit 57 for an advertisement to be presented to the accessing user based on the database created by the user-specific database creation unit 55, and performs an access process. The data is transmitted to the terminal 1 via the unit 51. The advertisement database creation unit 57 creates a database as shown in FIG. 6 and stores it in the storage unit 19 ′. As shown in FIG. 6, the advertisement database creating unit 57 stores a database in which items of “advertiser number”, “advertisement number”, and “keyword and weight” are provided, and data of each item is associated with each other. create.

The item "advertiser number" is a number given so that a person who provides an advertisement, a store, and the like can be uniquely distinguished. The item of “advertisement number” is an item provided for managing a plurality of advertisements provided by the advertisement provider given the advertiser number from the viewpoint of the advertisement number. The item “keyword and weight” stores information used when selecting an advertisement to be provided.

The charging database creating unit 58 creates a database as shown in FIG. 7 and stores it in the storage unit 19 '. That is, "Advertiser number", "Ad number", "
The access status "and the" total billing "are databases associated with each other. When the information provider pays, the billing is based on a basic fee for publication, presentation of information, the number of accesses, use of preferential treatment information, and the like. For this purpose, the charging database creating unit 58 manages the data as described above.

In the following description, it is assumed that billing processing is performed. However, if there is no need to perform billing processing, there is no need to provide the billing database creation unit 54.

Next, as an operation of the server 2, a process of creating a database for each user, particularly a process relating to text data written on a bulletin board will be described with reference to a flowchart of FIG. This database creation process is one of the processes executed by the information presentation program, and is started when it is determined that the bulletin board has been written or at a predetermined timing.

In step S1, the bulletin board data acquisition section 52 acquires text data written on the bulletin board and supplies the text data to the document attribute processing section 53 and the document content processing section 54. In step S2, the document attribute processing unit 53
Extracts attribute information from the text data supplied from the bulletin board data acquisition unit 52, groups documents based on the attribute information, and supplies the documents to the document content processing unit 54 and the user-specific database creation unit 55.

In step S3, the document content processing section 5
Reference numeral 4 extracts text data of the body of the document grouped by the document attribute processing unit 53, performs morphological analysis, and extracts the keyword as a keyword. In step S4, the document content processing unit 54 obtains the frequency of appearance of the keyword and the distribution status over a plurality of documents, and calculates the weight of the word serving as the keyword for each document group using, for example, the tf · idf method.

In step S5, the user-specific database creator 55 creates, for each document grouped by the document attribute processor 53, a database of attribute information of each document and weights of all keywords included in the document.

Next, referring to the flowchart of FIG.
The operation performed at the terminal 1 when writing on a bulletin board and displaying a banner advertisement will be described. In step S11, a predetermined URL (Uniform Resource Loca
Access to tor) is started. In this case, the predetermined URL refers to a bulletin board provided on the server 2,
URL to access for writing. In step S11, when the connection with the server 2 is completed,
In step S12, an input screen for the user ID is displayed on the display unit 18.

The user refers to the displayed user ID input screen and inputs his / her own user ID. As a process corresponding to this input, the input user ID is transmitted to the server 2 in step S13. When the transmitted user ID is received by the server 2 and the user's confirmation is completed by the processing of the server 2, the process proceeds to step S14.
At, a bulletin board is displayed on the display unit 18 of the terminal 1.
Further, in step S15, a banner advertisement is displayed together with the bulletin board. The displayed banner advertisement is advertisement data extracted from the advertisement database by the server 2 based on data corresponding to the user stored in the user-specific database, and is an advertisement suitable for the user's preference.

FIG. 10 is a diagram showing an example of a display screen displayed on the display unit 18 by the processing of steps S14 and S15. The display section 18 includes a writing section display section 71, a post display section 72, and a banner advertisement display section 73.
Is displayed. The writing column display section 71 is a column where the user of the terminal 1 accessing the server 2 can freely write a desired matter. Post display section 7 displayed below
2 displays a matter already written (posted) on the bulletin board by a plurality of users. Banner advertisement display section 7
3 displays a plurality of banner advertisements. For the banner advertisement, a predetermined operation such as a click is performed when it is desired to access an advertisement site that displays more detailed information.

Referring to such a screen, the user writes his / her opinion in the writing column display section 71,
The user can read opinions of other users displayed on the posting column display section 72 and search for advertisements of desired products from the banner advertisement display section 73.

Returning to the description of the flowchart of FIG. 9, in step S16, it is determined whether or not access to the advertisement site has been instructed. That is, the user refers to the screen as shown in FIG. 10 and determines whether there is an advertisement for which the user has desired to obtain detailed information from the banner advertisement display unit 73 and a predetermined operation has been performed. When it is determined that the access to the advertisement site has been instructed by performing the predetermined operation, the process proceeds to step S17.

In step S17, access to the advertisement site is started based on the site information included in the banner advertisement determined to have been operated. When access to the advertisement site is started, display on the display unit 18 and other controls are performed by data supplied from the site to which the advertisement site is accessed. From that advertising site, for example,
Data such as discount information is downloaded in step S18.

In some cases, the user may not be interested in the advertisement displayed on the banner advertisement display unit 73, but only write on the bulletin board or read information written on the bulletin board. In such a case, it is determined in step S16 that access to the advertising site has not been instructed, and the process proceeds to step S19. In step S19, it is determined whether the access to the bulletin board has been completed. In other words, it is determined whether an instruction to disconnect the connection with the server 2 has been issued.

If it is determined in step S19 that the end of the access to the bulletin board has been instructed, the process of the flowchart shown in FIG. 9 is terminated, and it is determined that the end of the access to the bulletin board has not been instructed. , The process returns to step S14, and the subsequent processes are repeated. When the access is terminated or when a predetermined process is performed, text data or the like written by the user in the writing column display unit 71 is transmitted to the server 2.

While such processing is performed, processing performed in the server 2 will be described with reference to the flowchart in FIG. In step S21, the access processing unit 51 makes an inquiry about the user ID to the accessing terminal 1. That is, user ID
Is transmitted to the terminal 1. When the user inputs the user ID assigned to the user on the transmitted user ID input screen, the data is received by the server 2.

In step S22, the access processing unit 51 of the server 2 instructs the search unit 56 to search whether the received user ID exists in the user-specific database. The search unit 56 specifies the user based on the user ID, and acquires information of the specified user (information stored in the item “word and frequency” illustrated in FIG. 5). Based on the acquired information, in step S23, the advertisement database created by the advertisement database creating unit 57 is searched to extract a banner advertisement suitable for the user's preference.

Specifically, among the data stored in the user-specific database shown in FIG. 5, the user ID is "01".
The following describes an example in which the user 2345 "accesses the user. The user with the user ID" 012345 "frequently uses words such as" fashion "," station ", and" mobile ". Can be determined to be interested in information related to.

The access processing unit 51 provides an advertisement (information) that may be of interest to the accessing user, ie,
In this case, information using words such as “fashion”, “station”, and “mobile” as keywords is extracted.

Further, some users frequently access the bulletin board, and some users only occasionally access the bulletin board. Therefore, information to be presented is extracted in consideration of the number of accesses. For example, for a user who accesses frequently, information with a high update frequency is preferentially extracted. For a user who accesses less, a site where other users can acquire detailed information ( (Advertising site) is preferentially extracted.

As described above, the information to be presented is selected by taking into account what the user may be interested in (words extracted from the e-mail sent and received by the user) and the number of accesses. It is possible to efficiently present information that matches the user's preference.

When the user can be specified and the data is extracted from the advertisement database, the process proceeds to step S24,
The bulletin board and the banner advertisement as shown in FIG. 10 transmit data to be displayed on the display unit 18 of the terminal 1.
If the user cannot be identified in step S22 (in the case of access from a user who has not been registered), the processing in step S23 is skipped, and in step S24, the user who has not been recognized is notified of the access. The data for displaying the screen is transmitted.

Referring to the screen displayed on the display unit 18 based on the data transmitted to the terminal 1 in step S24, if the user takes any action, the server 2
, Data on the action is transmitted. The access processing unit 51 of the server 2 determines in step S25
In, it is determined whether or not the data regarding the action performed by the user indicates an instruction to access the advertisement site (indicates that the banner advertisement has been operated). If it is determined that the instruction is for instructing access to the advertisement site, the process proceeds to step S26, and information on the advertisement for which access has been instructed is acquired. That is, information on which of the plurality of banner advertisements displayed on the banner advertisement display unit 73 has been operated is acquired.

The information obtained in step S26 is used for a charging process in step S27. The accounting process is performed by the accounting database creating unit 58 creating a database as shown in FIG. Specifically, in the billing process, the user uses the number of times a banner advertisement is presented to a user, the number of times the user accesses an advertisement site where detailed information can be obtained by referring to the presented banner advertisement, and benefits such as discounts. Billing can be done in stages based on information such as the number of times it has been taken.

If the charging process in step S27 is completed, or if it is determined in step S25 that access to the advertising site has not been instructed, the process proceeds to step S28, where the data written on the bulletin board is obtained. Is performed. The data written on the bulletin board
As described above, for example, when a button (not shown) for transmission is operated as a predetermined operation or when the access to the bulletin board is terminated, the terminal 1 transmits the message to the server 2.

When the transmitted data is received by the server 2, the process of step S28 is performed. In step S28, the access processing unit 51 of the server 2
Is supplied to the document attribute processing section 53 and the document content processing section 54. In step S29, a database for each user is created and stored in the storage unit 19 '. Since the creation of the database in step S29 has already been described with reference to the flowchart in FIG. 8, the description is omitted here.

When the same user accesses the bulletin board next time, the advertisement database is extracted from the database for each user created in this manner (step S23).
Is performed). As described above, advertisement data that matches the user's taste, in other words, products that the user is likely to purchase can be efficiently presented as the advertisement data.

In the above-described embodiment, a case has been described where a banner advertisement is presented, but information on a product may be presented directly. In other words, in the above-described embodiment, the processing after the banner advertisement is presented and the detailed information is presented is shifted to another site (server), but the processing until the user purchases the product is performed. To server 2
May be performed.

When the processing up to product purchase is performed in the server 2, the user-specific database created by the user-specific database creating unit 55 is as shown in FIG. FIG.
When compared with the database for each user shown in the above, the item "presentation advertisement and operation" becomes the item "display product and operation", and the operation of purchase is added to the operation to be stored. I have.

The advertisement database created and stored by the advertisement database creating unit 57 is a database as shown in FIG. As compared with the advertisement database shown in FIG. 6, “advertiser number” and “advertisement number” are changed to “merchandise provider number” and “article number”, respectively.
An item “product detailed information” is added. The “product detailed information” includes an image file for presenting the appearance of the product to the user.

The accounting database created and stored by the accounting database creation unit 58 is a database as shown in FIG. As compared with the charging database shown in FIG. 7, “advertiser number” and “article number” are changed to “article provider number” and “article number”, respectively. The information to be managed is increased, and the unit price of the product, the number of presentations, the number of accesses to the detailed information, the purchase, and the total amount of the purchase are managed. Based on this information, the amount to be charged is determined in stages.

Next, the operation of the terminal 1 performed based on these databases will be described with reference to the flowchart of FIG. The processing in steps S31 to S36 is basically the same as the processing in steps S11 to S16 in the flowchart shown in FIG. 9, and thus the description thereof is omitted. However, in step S35, FIG.
The advertisement of the product itself is displayed on the banner advertisement display 73 among the screens displayed on the display 18 shown in FIG. The determination process in step S36 determines whether or not there is a selected product among the products displayed on the banner advertisement display unit 73.

If it is determined in step S36 that the user has selected a desired product from the displayed products, the information is transmitted to the server 2.
The server 2 receives the transmitted information and sends back detailed information corresponding to the information to the terminal 1. Based on the returned detailed information, a product detail screen is displayed in step S37. The user refers to the detail screen and determines whether to purchase the product.

In step S38, it is determined whether or not the user has instructed the purchase of a product, and information based on the determination is transmitted to server 2. Data corresponding to the information is sent back from the server 2, and a confirmation screen is displayed in step S39 based on the information. That is, if it is determined in step S38 that the user has decided to purchase the product, a screen for confirming the purchase intention, selecting a payment method, and entering the address of the destination of the product is displayed. When it is determined that the user has canceled the purchase of the product, a screen for confirming the intention not to purchase is displayed.

On the other hand, if it is determined in step S36 that a product has not been selected, the flow advances to step S40 to determine whether termination of access to the bulletin board has been instructed. If it is determined in step S40 that the end of the access to the bulletin board has not been instructed, the process returns to step S34, and the subsequent processing is repeated. The processing of the flowchart thus completed is terminated.

While such processing is performed in the terminal 1, the server 2 executes the processing of the flowchart as shown in FIG. The processing in steps S51 to S55 is basically the same as the processing in steps S21 to S25 in the flowchart shown in FIG. 11, and a description thereof will be omitted. However, in step S53, based on the information on the user's preference acquired in the process of step S52, the product database is searched, product data is extracted, and transmitted to the terminal 1.

When extracting the product data from the product database, the search unit 56 uses a bulletin board (shopping site).
The frequency of access to the URL may also be taken into account in consideration of the extraction. Specifically, data on discounted products for a limited time is preferentially extracted for a user with a large number of accesses, or another user frequently purchases a user with a small number of accesses. Data on the top selling products is preferentially extracted.

In step S55, it is determined whether or not a product has been selected. If it is determined that the product has been selected, the process proceeds to step S56. If it is determined that the product has not been selected, the processes in steps S56 to S58 are skipped. Then, the process proceeds to step S59. In step S56,
The search unit 56 searches and reads out detailed information of the selected product from the product database based on the information on the selected product transmitted from the terminal 1, and reads the detailed information of the product.
1 to the terminal 1.

When the user refers to the detailed information of the product transmitted to the terminal 1 and decides to purchase or cancel the product, the information is transmitted to the server 2 and received. In order to confirm with the user whether the received information (purchase or cancellation) is correct, data of a confirmation screen is sent in step S57.
This confirmation screen is a screen for confirming purchase or a screen for confirming cancellation, as already described in the description of the processing in step S39 in FIG.

When the process in step S57 is completed, the flow advances to step S58, and a billing process is performed. When the accounting process is completed, the process proceeds to step S59, where data written on the bulletin board is acquired. The acquired data is used in step S60 for creating a database. The processing of steps S59 and S60 is basically the same as the processing of steps S28 and S29 in the flowchart of FIG.

As described above, since information on the user's preference is accumulated from the data written on the bulletin board by the user, not only does the user not have to take the trouble of answering a questionnaire and the like, but also the user can be saved. It is possible to accumulate information as to preferences that are not conscious of itself. In addition, since the information is updated every time the user accesses the server 2, no management work is required. Furthermore, since the product information is presented based on the accumulated information, it is possible to increase the probability of purchasing the product.

Next, the program storage medium of the present invention will be described. The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software can execute various functions by installing a computer built into dedicated hardware or installing various programs. It is installed from a program storage medium to a possible general-purpose personal computer or the like.

As shown in FIG. 2, a program storage medium which is installed in a computer and stores a program which can be executed by the computer is provided separately from the computer (terminal 1) in order to provide the user with the program.
