Description

The present invention relates to an information personalization system that assists a website that provides users with information in a predetermined field, and individually displays or transmits information that is presumed to be of interest to each user.

Websites that provide various types of information to users via the Internet are generally known.

Systems that display a so-called banner advertisement when a user accesses a predetermined website are also widely known.

Considering advertisements, including banner advertisements, as a type of information, it can be said that the technique of displaying banner advertisements is one of the techniques related to the present invention for displaying information presumed to be of interest to users.

Techniques using cookies are known for selecting and displaying advertisements.

Technology that uses cookies assigns the identifier of the website accessed by the user as a cookie to the IP address of the user's terminal device, and when the user accesses another website, an advertisement related to the cookie is displayed on the website. It is a technology to display as

Also known is a so-called search-linked advertisement technology for selecting and displaying advertisements.

Search-linked advertising is a technology for displaying, when a user enters a predetermined search keyword, an advertisement highly relevant to the search keyword as a banner advertisement on a homepage accessed by the user.

Various proposals have been made regarding the "relationship" between the search keyword and the advertisement to be displayed. That is, a method of assigning a plurality of keywords to advertisements in advance and selecting advertisements having keywords that match the search keyword entered by the user; Various techniques have been proposed, such as a selection method and a method of selecting advertisements that are frequently displayed based on a search keyword input by a user through statistical processing.

Japanese Patent No. 5577385

However, with the conventional technology described above, it was not possible to accurately and individually specialize (customize) the information that the user is interested in and display it. For example, on websites that comprehensively provide specialized information such as life sciences, it is difficult for users to guess information that interests them due to the specialized nature and fluidity of the information.

For example, on websites that comprehensively provide specialized information such as life sciences, the information is often fluid due to cutting-edge research and trends. Users tend to want to obtain information on hot topics from websites that provide such fluid information, so information that interests users is fluid. For this reason, in many cases, the information that the user is interested in is not the information that the user is interested in, even if the information is simply guessed from the information that the user has accessed in the past.

On the other hand, it is conceivable to always add a keyword, which is a tag for searching, to new information and provide information close to the user's search keyword. However, attaching an appropriate search tag keyword to the latest information each time requires speed and a great deal of effort. For example, even if a keyword is assigned to new information, it is difficult to assign candidate search keywords because the information itself is new. Furthermore, even with linguistic processing and statistical processing, it is difficult to match with search keywords due to expertise. On the other hand, it is conceivable to perform advanced linguistic processing using high-performance hardware and software, but this requires complex algorithms, huge amounts of data, and high-performance hardware.

In addition, the conventional technology does not distinguish between past and present fields in which the user is interested, or presumes the user's field of interest by biasing either past or recent fields of user interest. rice field. For this reason, it has not been possible to timely provide information that takes into account the user's past and present interests.

Furthermore, the conventional technology does not take into account the possibility that the user's interests may span multiple fields, and it is not possible to provide information that matches the fields in which the user is interested in a plurality of fields of interest. .

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG.

FIG. 1 shows the overall configuration of an information personalization system 1 according to a first embodiment of the present invention, exemplary websites A and B assisted by the information personalization system 1, and users U1, U2, . . . Un. It is a block diagram.

In this specification, information personalization system 1 "assisting" website A and website B means, but is not limited to the operation or processing described below, , Un is estimated from the browsing history of each user U1, U2, . This means enabling us to serve you specialized and relevant advertisements.

Websites A and B have web servers 2, but when receiving assistance from the information personalization system 1, the information personalization system 1 is provided with browsing histories of users U1, U2, . . . It cooperates with the control means 15 of the information personalization system 1 via the communication means 3 of the information personalization system 1, such as by sending and receiving information on advertisements to be advertised.

Websites A and B in this embodiment are websites that provide information on a network, preferably on the Internet. Although two websites A and B are shown as websites in FIG. 1, the number of websites assisted by the information personalization system 1 is arbitrary. The website A shows a plurality of articles A1, A2, . . . , An and advertisements Ad1, Ad2, . Not limited. Website B provides digital health information B1, B2, . . . , Bn and matching information Bm1, Bm2, .

As an example, Website A is a membership-based information service website where top suppliers that form a leading supply chain in the life science industry provide a wide range of information on their technologies, products and services. It is a specialized portal site that displays and disseminates various information.

On the other hand, website B is a site that provides overseas digital health information and transmits domestic and overseas matching information, for example.

As a specific example of the following explanation, the above website A will be taken up, and a special portal site related to life science will be explained as an example. It should be noted that the following description will be made with website A as an example, but it also applies to any other website, including website B. Also, as used herein, "field" should be interpreted broadly, meaning that any collection of information constitutes a "field."

Specifically, in the above example of the specialized portal site, the articles A1, A2, . The latest information on corporate seminars, the latest information on virtual exhibitions virtually exhibited by participating companies on the portal site, the latest information on events in the life science industry, and the like can be included.

Articles A1, A2, . . . , An may contain information in a broad sense. It is related to a specific company, such as product/service information, and includes "advertisement" in a general sense.

In the present invention, in order to customize the information that the user is interested in, the information is classified by the concept of "field". This is because the classification by "field" is more exhaustive than the classification by "keyword", there is no omission by the keyword, and it is easy to handle as a collection of information.

The latest articles A1, A2, . . . , An are published at any time. Articles A1, A2, . Related to auditing.

Articles A1, A2, .

It should be noted that various lower-level fields can be defined according to higher-level fields. In addition, regarding life sciences, the classification of fields is not limited to the above classification.

For example, subfields of life science can be classified into pharmaceuticals, medical devices, regenerative medicine, cosmetics, foods, facilities/equipment/engineering, and new technologies. In addition, further sub-fields of sub-fields can be defined. For example, regulatory, quality systems, and manufacturing systems can be defined as sub-areas of the pharmaceuticals. In addition, regulation (pharmaceuticals), non-clinical, clinical, and inspection audits can be defined as subfields of the above regulations, and drug substances, formulations, packaging, quality testing, and warehouses can be defined as subfields of the above manufacturing systems. Management can be defined.

In FIG. 1, only articles A1, A2, An are illustrated on website A, which means n articles A1, A2, . Users U1, U2, . . . Un can access website A. When any user among users U1, U2, ..., Un accesses website A, web server 2 of website A establishes communication with the user and serves as the website server for the user. . The information personalization system 1 has a communication means 3 and obtains a history of user requests and responses from the web server 2 via the communication means 3 . Accordingly, when the user searches or browses the website A or requests an article to be viewed, the information is shared by the information personalization system 1 via the communication means 3 .

As shown in FIG. 1, the information personalization system 1 includes, in addition to the communication means 3, a user management database 7, a user browsing field database 8, a user interest field database 9, an article It has a database 10 , an advertisement database 11 , a product/service information database 12 , advertisement display frequency management means 16 , and product/service information display frequency management means 17 .

The information personalization system 1 also has user browsing history management means 13, personalization point calculation means 14, and control means 15 as means for processing data.

The user management database 7 is a database that stores and manages information on users U1, U2, .

As shown in FIG. 2, the user management database 7 stores, for example, user U1, U2, . memory management.

User registration and updating in the user management database 7 may be performed under the control of the control means 15, or a dedicated registration means may be provided.

The article database 10 is a database that stores and manages articles A1, A2, . . . , An and their related fields.

The article database 10 stores the date and time when the articles A1, A2, . memorize and manage.

As shown in FIG. 3, articles A1, A2, . . . , An can contain information related to multiple fields. The areas are, in this example, Regulatory (Pharmaceutical), Nonclinical, Clinical, FDA, Digital Health, Validation, and Inspection Audit. In FIG. 3, the fields related to each article A1, A2, . , T7, and field tags T1, T2, . . . , T7 are associated with articles A1, A2, .

Here, all articles have a common set of "related fields". “Related fields” refer to subfields of the above-mentioned life sciences, etc. It is possible to select and adopt an appropriate classification level, such as subfields of life sciences, subfields of subfields, and subfields of subfields. , or different classification levels can be combined into a set of related fields.

In this embodiment, the article database 10 manages the fields to which the articles A1, A2, . . . , An can adopt any information system for specification as long as it is information that can specify them. In this regard, the same applies to field tags T1, T2, . . . , T7 that appear in the following description.

In the following description, field tags are described using a set of regulation (pharmaceutical) T1, non-clinical T2, clinical T3, FDA T4, digital health T5, validation T6, and inspection audit T7 for convenience of explanation. is not limited to the field of

Next, the user interest field database 9 will be described.

The user interest field database 9 is a database that stores and manages fields in which the users U1, U2, . Note that the “original field of interest” is not a fluid field of interest that is a hot topic from time to time, but is, for example, a manufacturing, providing, or research field to which the user belongs.

As shown in FIG. 4, the user interest field database 9 has the same set of field tags T1, T2, . In FIG. 4, the fields in which each of the users U1, U2, . As described above, in practice, the fields in which each user U1, U2, . A single user can register multiple fields as original fields of interest.

The user's original field of interest is preferably registered by the user himself/herself when the user registers as a member. Moreover, when the user originally wants to change the field of interest, it is preferable that the user's original field of interest can be changed.

Next, the user browsing field database 8 will be described.

As shown in FIG. 5, the user browsing field database 8 stores and manages the fields to which the articles browsed by each user are related (herein referred to as "user browsing fields"). The user browsed field database 8 has the same set of field tags T1, T2, . . . , T7 as the article database 10, that is, the same set of related fields. In addition, although FIG. 5 shows the viewing fields of the user U1 as an example, each of the users U1, U2, . . . , Un has similar viewing field data. In FIG. 5, the fields of articles browsed by the user U1 are circled for easy conceptual understanding. Specifically, when the user browses a predetermined article, the field related to the article registered in the article database 10 is recorded in the user browsed field database 8 . As described above, the user's browsing field circle marks shown in FIG. 5 are stored and managed by field tags T1, T2, . . . , T7 or corresponding field specifying information.

The date and time when the user U1 browsed the article (both of them are collectively referred to as “browsing time”), field tags T1, T2, . It is stored and managed in the user browsing field database 8 in association with the viewing event of U1. When multiple articles in the same related field are viewed, multiple records are recorded, but when one article covering multiple related fields is viewed, it is recorded as one case.

Next, the advertisement database 11 will be explained.

The advertisement database 11 is a database that stores and manages advertisements. Here, the "advertisement" is distinguished from the "article" shown in FIG. 1, and refers to page-format image data to be pasted on a home page or sent in the form of e-mail. Advertisements are preferably registered and managed in advance in the information personalization system 1 based on a contract with the advertiser.

As shown in FIG. 6, the advertisement database 11 has a portion for storing and managing information on advertisers S1, S2, S3, . .

The part that stores and manages the information of advertisers S1, S2, S3, . . . is, for example, as shown in FIG. It stores and manages identification information, contract information, payment information, etc., and advertisements provided by each advertiser. The advertisement database 11 cooperates with the advertisement display frequency management means 16 when performing processing for determining advertisements based on the advertisement display frequency, which will be described later. The advertisement display frequency management means 16 counts and stores and manages the number of times each advertisement is displayed for a predetermined period, for example, a month.

The part that stores and manages the related fields of advertisements is, for example, as illustrated in FIG. 6, related field tags T1, T2, . It stores and manages field tags T1, T2, .

Here, the related field of the advertisement is the related field in which the advertisement should be displayed or transmitted, that is, the field to which the advertisement is related and suitable for displaying or transmitting the advertisement.

There may be a plurality of tags for the relevant field of the advertisement, but a single tag may also be used. In the following description, it is assumed that there is one field tag for the field related to the advertisement. That is, the advertiser specifies in advance which advertisement is to be issued for which field tag. The field tags specified by the advertiser have the same set of field tags T1, T2, . In FIG. 6, related fields in which advertisements are displayed or sent are circled for conceptual ease of understanding, but are actually stored as field tags T1, T2, . . . , T7. and managed. Although not shown, related fields of advertisements of advertisers other than advertisers S1 and S2 are stored and managed in the same manner.

Next, the product/service information database 12 will be described.

The product/service information database 12 is a database that stores and manages information on products or services of vendors that provide products or services. Here, "product or service" is information about a product or service provided for convenience to users, such as engineering service, consulting service, or educational service. "Products or Services" are provided by a Professional Services Provider. "Products or services" are distinguished from advertisements, but are information on products or services available in the user's field of interest and information on vendors providing them. Product/service information may include a description of a product or service and access to the description of the product or service, ie data of the provider of the product/service, a link to the provider's home page, and the like.

As shown in FIG. 7, the product/service information database 12 stores and manages related fields of products/services provided by professional service providers. The product/service information database 12 has the same set of field tags T1, T2, . . . , T7 as the article database 10 does. In FIG. 7, the fields related to products and services are marked with circles for easy conceptual understanding. . . , stored and managed in T7. A single product or service can relate to multiple fields. For example, as illustrated in FIG. 7, a plurality of field tags T1, T2, . ) are stored and managed. Although not shown, information of other vendors providing other products/services is stored and managed in the same manner.

As will be described later, the product/service information database 12 cooperates with the product/service information display frequency management means 17 when performing processing for determining information on products/services to be provided based on the display frequency. The product/service information display frequency management unit 17 counts and stores and manages the number of display times of each product/service information for a predetermined period, for example, a month.

The information personalization system 1 of the present embodiment uses field of interest points given when the user registers as the user's original field of interest (original field of interest) and browsing points given when viewing an article. Calculate personalization points.

Based on the personalization points calculated above, the information personalization system 1 infers that the field with high personalization points is the field in which the user is currently interested (current field of interest), and displays advertisements that match the user's current field of interest on the web. Site A is notified, and the web server 2 of website A displays the advertisement along with the page requested by the user based on the information in the notification.

FIG. 8 shows the flow from the registration of the user's original field of interest to the determination of the priority of the fields that the user is currently presumed to be interested in. In FIG.
Field of Interest Points of User U1
First, the field in which the user originally has an interest is registered (step S10). As an example, user U1 registers regulation (pharmaceuticals), non-clinical, and clinical as fields of interest on 2020/01/05.

User U1's original field of interest is stored and managed in user field of interest database 9 . These registered fields of interest are the "original fields of interest" of the user.

The user's original field of interest may be registered by preparing a registration page on the web server 2 and writing it to the user's field of interest database 9 under the control of the control means 15 .

Interest field points are generated by registering the user's original field of interest (step S20).

The field of interest points can be 10 points each, and in the above example, user U1 is given 10 field of interest points each for regulation (pharmaceuticals), non-clinical, and clinical.

When the user browses the article on the website A after registering the original field of interest, the browsing history is recorded (step S30). In the above example, if user U1 browses articles as follows, the browsing history is recorded.
Browsing history of user U1
2021/01/06 Viewed 1 article tagged with regulation (pharmaceuticals) and FDA
2021/01/08 Read 1 article with non-clinical, digital health and FDA tags
2021/01/20 Read 1 article tagged digital health and validation
2021/01/27 Inspection audit and viewing 12 articles with FDA tags The user's browsing history is sent from the web server 2 of the user's website A to the information personalization system 1 via the communication means 3. and recorded in the user browsing field database 8 by the user browsing history managing means 13 under the control of the control means 15 .

Viewing points are generated by the user's viewing (step S40). For example, reading one article in one field is set to 1 point, and if the article matches the user's field of interest, the reading point is weighted to 1.2 points, for example. When multiple articles in the same field are browsed, the browsing points per article are multiplied by the number of browsed articles to calculate the browsing points.

Next, personalization points are calculated based on the field of interest points and browsing points (step S50).

Personalized points are calculated by determining a calculation period and summing interest field points and browsing points during the calculation period. The calculation period is a period of a predetermined length going back from the present. An example of calculating the personalized points of user U1 in the above example with a calculation period of January 2021 is shown below.

Based on the calculation of personalization points, personalization priority is determined as shown in the table below in descending order of personalization points (step S60).

パーソナライズポイントは、ユーザが本来の興味分野と、閲覧記事の関連分野と、閲覧件数がファクターになっているため、算出されたパーソナライズの優先順位が高いほど当該ユーザが現在興味を有している分野と推測することができる。

Personalization points are based on factors such as the user's original interest field, related fields of articles viewed, and the number of views. Therefore, the higher the personalization priority calculated, the more the user is currently interested in the field. can be inferred.

Here, it should be noted that according to the information personalization system 1, even if it is not the user's original interest field, the "FDA" field, which the user has shown interest in and browsed recently, has the highest personalization priority. It is what it is.

In other words, according to the information personalization system 1, the user's original interest field has a high probability of appearing at a high personalization priority, but even if it is not the user's original interest field, the field that is frequently viewed recently also has a high personalization priority. is likely to appear in

This is an advantage of being able to estimate the user's field of interest by taking into account both of them, without being biased towards either, whereas the conventional technology is biased towards either the original field of interest or the most recent field of interest. There is

It should be understood that the field of interest of the user estimated by the information personalization system 1 includes not only the immediate field of interest of the user but also the field of original interest.

Personalized points can be calculated by the personalized point calculator 14 . When calculating the personalized points, the personalized point calculation means 14 accesses the user browsing field database 8 and the user interest field database 9 to acquire necessary user browsing points and interest field points. A formula necessary for the calculation is held in the personalized point calculation means 14, and the personalized point calculation means 14 calculates personalized points based on the formula. The processing by the personalized point calculation means 14 is performed under the control of the control means 15 , or the calculation of the personalized points can be part of the processing by the control means 15 .

Note that the control means 15 controls the operation of the entire information personalization system 1 in addition to the control described above. For example, when a user accesses website A, an identifier identifying the corresponding advertisement is obtained from the advertisement database 11 according to the personalization priority of the user, and the web server of website A is obtained via the communication means 3. 2. Upon receiving the notification, the web server 2 transmits the advertisement indicated by the identifier together with the image to be transmitted to the user, and causes the user's terminal device to display the advertisement. Further, the control means 15 transmits the identifier of the advertisement of the user's field of interest to the website A via the communication means 3 at a predetermined timing. Website A that has received the notification transmits the advertisement to the user via the mail server 6 .

As is clear from the above description, the information personalization system 1 does not need to guess the user's field of interest from the user's search keywords. It does not require a high performance data processor to process it. Nevertheless, the user's field of interest is estimated by the information personalization system 1 based on the user's own selection, so the user's field of interest can be estimated with high accuracy.

In addition, for articles in specialized fields, there is no need to think of appropriate keywords and assign multiple keywords to each article. Such labor can be greatly reduced, and new articles can be quickly posted on the website.

By calculating personalization points, the information personalization system 1 can display to the user an advertisement that matches the field in which the user is interested, at the timing when the user accesses the website. In addition, the information personalization system 1 can send advertisements matching the user's field of interest to the user through the mail server of the website.

As already explained with respect to the advertisement database 11, it is possible to have a plurality of related field tags, but in this example, the advertisement is related to only one field tag, and the advertiser decides which field tag to display which advertisement. is specified in advance. Therefore, for each user, an advertisement with a corresponding field may be displayed in accordance with each user's personalization priority.

In addition, when the user accesses a predetermined article, the information personalization system 1 is configured so that when the article is related to a plurality of related fields, for example, the field tags attached to the article are "digital health" and "FDA". , an advertisement designating "digital health" and an advertisement designating "FDA" may be displayed together with the article.

However, the space for advertisements that can be displayed together with articles is limited, and when there are a large number of advertisements, advertisements that have been displayed less frequently are displayed preferentially for the sake of fairness among advertisers.

The advertisement display frequency management means 16 performs the process of preferentially displaying an advertisement with a low display frequency. The processing of the advertisement display frequency management means 16 will be described below with a specific example.

As a specific example, if the field tags attached to the article are "digital health" and "FDA", an advertisement requesting to be displayed with the article of "digital health" and an advertisement to be displayed with the article of "FDA" A case where there are many advertisements requesting is explained. Suppose that the number of monthly impressions of these advertisements was as follows.
Ad display example

このような場合は、表示回数が少なかった広告から順番に、Ｄ１，Ａ２，Ｂ１，・・・を、表示スペースの範囲内で表示すればよい。

In such a case, D1, A2, B1, .

Even when advertisements are sent by e-mail and there is a limit to the number of advertisements to be sent, advertisements sent less frequently can be preferentially sent by similar processing.

By having the advertisement display frequency management means 16, it is possible to give priority to advertisements having a low display frequency and display the advertisements evenly. Also, relevant advertisements can be displayed evenly for a combination of multiple related fields, in the above example the combination of "digital health" and "FDA." That is, instead of displaying a fixed number of advertisements in each related field, the combined related fields can be treated as one field, and advertisements with a low display frequency in the one field are prioritized. ads can be displayed evenly.

Note that the display order of advertisements to be displayed together with articles may not be determined depending on the display frequency. For example, ads can be displayed in a certain order. In this case, the advertisement display frequency management means 16 may not be provided.

Further, the information personalization system 1 can display or transmit so-called recommended articles by calculating personalization points.

In other words, the information personalization system 1 can display or transmit articles having field tags up to a predetermined rank of personalization priority to users for whom personalization points have been calculated.

For example, if the user has personalization priorities in the order "FDA", "Regulation (pharmaceutical)", "Non-clinical", "Inspection audit", "Clinical", "Digital health", "Validation", Articles with "FDA", "Regulation (Pharmaceuticals)", "Non-Clinical" as related fields can be displayed or sent along with personalization priorities.

As the number of related fields increases, it is possible to display or transmit articles that match the user's field of interest. However, as the number of related fields increases, the number of articles that can be displayed or sent decreases, so articles up to an appropriate personalization priority are displayed or sent.

In the information personalization system 1, when a user accesses a website, the control means 15 stores identifiers of articles having combinations of related fields up to a predetermined rank in accordance with the user's personalization priority. and send it to the website. Upon receiving the article identifier, the website sends the article together with the data of the page requested by the user, or sends the article to the user via the mail server at a predetermined timing.

In that case, the articles to be displayed or transmitted are preferably displayed or transmitted in order from the newest article.

According to the information personalization system 1 of the present invention, since the article database 10 also manages the date and time when an article is published, it is possible to provide the user with not only the user's field of interest but also newly arrived articles.

According to the information personalization system 1, since it is possible to display or transmit articles having field tags that match combinations of field tags up to a predetermined order of personalization priority, it is possible to display or transmit articles that match in one field. can display or transmit a recommended article that the user is interested in with much higher accuracy than when displaying or transmitting . In addition, even if an advertisement has multiple related field tags, it is possible to display or transmit an advertisement having a field tag that matches a combination of field tags, compared to displaying or transmitting an advertisement that matches a single field. Therefore, it is possible to display or transmit advertisements that are of interest to the user with much higher accuracy.

In addition, since the personalization priority considers not only the field in which the user is originally interested, but also the field in which the user has recently shown interest, it is possible to recommend articles in the field in which the user is actually interested.

When sending articles by e-mail, there is no space limit, but it is sufficient to send articles up to a predetermined number.

Newly arrived articles in each field can be displayed or sent to users who have not registered as members or users who have not yet calculated personalized points.

In this way, according to the information personalization system 1, since articles are displayed or transmitted in order from the newest, older articles cannot be displayed or transmitted due to the similarity of articles as in the conventional art. Absent.

As already described with respect to the product/service information database 12, there may be multiple field tags associated with the product/service information. In this case, the information personalization system 1 can display or transmit product/service information having related fields (field tags) up to a predetermined order of personalization priority for users for whom personalization points have been calculated. .

However, if the space for displaying product/service information is limited and there is a large amount of product/service information, pages with less frequently displayed product/service information are displayed preferentially.

The product/service information display frequency management means 17 performs the process of preferentially displaying the pages of the product/service information whose display frequency is low. The processing of the product/service information display frequency management means 17 will be described below with a specific example.

As a specific example, the user's personalization priority is 1st "digital health", 2nd "FDA", and 3rd "clinical", and a product/service information page having "digital health" in the field tag, and " A case where there are many product/service information pages having field tags of "FDA" and many product/service information pages having field tags of "clinical" will be described. Assume that the number of monthly display times of these product/service information pages is as follows.
Product/service information page display example

表示すべき製品・サービス情報のページは、まずパーソナライズ優先順位１位の分野タグ「デジタルヘルス」の中で表示回数最小のＢ１を選択し、次にパーソナライズ優先順位２位の分野タグ「ＦＤＡ」の中からそれまでに選択済みの表示ページＢ１を除いて表示回数が少ない順にＤ１を選択し、次にパーソナライズ優先順位3位の分野タグ「臨床」の中からそれまでに選択済みの表示ページＢ１，Ｄ１を除いて表示回数が少ない順にＡ２を選択する。

For the product/service information page to be displayed, first select B1, which has the lowest display count among the field tags "digital health" with the first personalization priority, and then select the field tag "FDA" with the second personalization priority. Select D1 in descending order of the number of times of display, excluding the display page B1 that has been selected so far, and then select the display page B1 that has been selected so far from the field tag "Clinical" with the third personalization priority, Except for D1, A2 is selected in descending order of display frequency.

Next, in the second round, A1 is selected from the field tag "digital health" with the highest personalization priority again, excluding the display pages B1, D1, and A2 that have been selected so far, in order of the number of times of display, and then selecting A1. Then, from the field tag "FDA" with the 2nd personalization priority, excluding the display pages B1, D1, A2, A1 that have been selected so far, select B2 in order of the number of times of display, and then select the 3rd personalization priority. E1 is selected from the field tag "Clinical" in descending order of the number of times of display, excluding display pages B1, D1, A2, A1, and B2 that have been selected so far.

From the third round onwards, repeat the same procedure as the first and second rounds, skip field tags for which all display pages have already been selected, and reach the allowable number of field tags with display pages remaining. Select the display page up to .

In this example, the resulting display order is B1, D1, A2, A1, B2, E1, C1, and the corresponding product/service information pages are displayed in that order.

Note that the display order of product/service information may not be determined depending on the display frequency. For example, product/service information can be displayed in a fixed order. In this case, the product/service information display frequency management means 17 may not be provided.

According to this information personalization system 1, thus, products and Since it is possible to display or transmit service information, compared to displaying or transmitting matching product/service information in one field, product/service information in fields in which the user is interested is provided with much higher accuracy. be able to.

In addition, the personalization priority takes into consideration not only the field of interest that the user was originally interested in, but also the field that the user has shown interest in recently. can be provided.

When sending the product/service information by e-mail, there is no space limit, but the product/service information may be sent up to a predetermined number.

In the embodiment described above, the field of interest points are 10 points, and the browsing points are 1 point or 1.2 points, but the number of points is not limited to this. Interest points or viewing points are adjustable. Means for adjusting field of interest points or viewing points may be provided.

Further, in the above-described embodiment, the period for calculating the browsing points is one month, but the period for calculating the browsing points is not limited to this. If the calculation period is reasonably short, it can reflect the user's immediate area of interest, but if it is too short, it will produce inaccurate results. A means for adjusting the period for calculating the browsing points may be provided.
