Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention According to the present invention, information about a content that a user is interested in is acquired by acquiring a content ID uniquely assigned to the corresponding content. In an environment managed by the system, by deleting the content information that is guessed unnecessary or set on the system side, the management burden on the individual is reduced and the browsing efficiency of the content information space is improved. As a result, the present invention relates to a content information management system and an acquired content information management server for promoting acquisition of new content information.

[0002]

2. Description of the Related Art With the recent remarkable development of the Internet, a WWW system for providing various digital contents on a network has become widespread, and a huge amount of contents can be used via the WWW system. . In such an environment, as a method of acquiring necessary or interested content,
There is also a method of downloading the relevant content to the own terminal and holding it, but there is a problem with the resource for storing it on the own terminal, and the problem that the updated content is not reflected when the content is updated sequentially. Occur.
Therefore, in order to avoid this, for example, the acquisition of the target content such as a bookmark (Book Mark) on the Web is regarded as the acquisition of the resource location (URL on the Internet) of the content, and this is managed. It is common to

As described above, with respect to the target content, the content information which is the "information regarding the content" (the UR of the content in the example of the bookmark)
L, title, etc.) and the need to manage this will increase in the future. Specifically, in the communication / broadcast fusion service triggered by digital broadcasting, it is possible to clip content information related to broadcast video with a simple operation, and most paper media such as magazines and books have recently been clipped. Then the URL of the related homepage
Has also been printed, and optical devices for recognizing printed URLs and easily importing them into personal computers have also appeared. In addition, considering the environment in which content information is added to advertising media such as posters and leaflets, and it is easy to obtain this,
It can be easily assumed that the number and the number of opportunities to acquire content information will increase in the future.

On the other hand, regarding the management method of the content information acquired in this way, conventionally, for example, there is a method of registering / accumulating a bookmark as a function on the browser in the own terminal. However, this requires the user to actively manage. For example, even if you intend to register as a bookmark for one-time acquisition,
Since automatic deletion is not performed, it is necessary to check all the information and delete unnecessary information in order to organize it. On the contrary, if such management is not performed, the content was registered as a bookmark, but now, the corresponding content, in this case, the Web page itself has been deleted, or the content was originally limited in time, At present, contents that have become invalid are mixed and there is a possibility that the user needs to browse more bookmarks than necessary and a psychological burden occurs when an access error occurs.

[0005]

[Problems to be Solved by the Invention] As described above,
In an environment in which the chances of knowing various contents on the network through various media increase and the contents information can be easily acquired, the user can collect information about a large number of contents. However, while collecting and accumulating, there is a mixture of what is needed and what is not needed, so it not only requires extra effort when searching for what is needed, but also requires less attention to each individual when listing. turn into. Also, when you actually tried to use it, you could browse the content that you thought you could browse because the content was outside the valid period or you tried to browse the content, but the content was deleted. The fact that it did not exist is not convenient for the user.

As described above, even if a user acquires various contents, he / she does not always have an interest or interest in each content, and the contents themselves are irrelevant regardless of the intention of the user. Alternatively, if the information obtained from the information has an expiration date or the like, it will eventually become invalid or become unnecessary, and the usability of the use environment as described above will occur.

That is, the present invention has been made in view of the above-mentioned problems expected in the future as to the management of the content information as the information about the content acquired by the user. Server positively organizes the content information that is considered unnecessary, reduces the management burden on individuals and improves the browsing efficiency of the content information space, and as a result, promotes the acquisition of new content information.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of a block diagram of the entire configuration of a content information management system showing an embodiment of the present invention.

In the network 1 such as the Internet,
The user terminal 2 that mainly acquires the content ID and browses the content, the content ID that the user acquired on the user terminal 2, and the operation history on the user terminal 2 are managed for each user ID. The content attribute, which is the additional information of the content, is managed for each content ID, and
At a predetermined timing, the acquired content information management server 3 that deletes unnecessary content IDs is communicated with the acquired content information management server 3 to add a content ID,
The content provider terminal 4 capable of updating, deleting, and adding, updating, and deleting content attributes is connected.

Next, each device constituting the above system will be described.

The user terminal 2 has a user ID setting means 21 for inputting and setting a user ID, a content ID acquiring means 22 for acquiring a content ID, and an acquired content ID managed by the acquired content information management server 3.
A content ID browsing means 23 for browsing the content, a content display means 24 for the user to browse the content,
In the user information transmitting means 25 for transmitting the acquired content ID and the operation history at the own terminal to the acquired content information management server 3, and the content ID managed by the acquired content information management server 3, Although not shown in the figure, it includes a content deleting unit 26 for deleting the content ID, and a communication unit necessary for the above, a storage unit for storing data necessary for each processing, and a necessary operation. It is composed of an input means such as a mouse and a keyboard for inputting various information and a control means for controlling them.

The acquired content information management server 3 includes a content attribute management means 31 including means for accumulating content attributes previously assigned to content by a content provider, and means for managing the content attributes for each content ID, and the content attribute management means 31. A user information management unit 32 that manages, for each user ID, user information including the content ID acquired at the user terminal 2 and the operation history at the user terminal 2, and is designated at a predetermined timing. Of the content IDs included in the user information corresponding to the user ID,
Although not shown in the drawing, the unnecessary content ID deleting unit 33 for deleting the content ID determined to be unnecessary and the content access managing unit 34 for managing the user access to each content are provided. Consists of a communication means, a storage means for storing data necessary for each processing, an input means such as a mouse or a keyboard for inputting information necessary for operation, and a control means for controlling them. To be done.

The content provider terminal 4 adds / updates / deletes the content ID and adds / updates / deletes the content attribute to / from the content attribute management means 31 of the acquired content information management server 3 by the content attribute update means 41. Although not shown in the figure, the communication means for communicating with the acquired content information management server 3 via the network 1 and the data necessary for each processing are stored in the figure. It comprises a storage means, an input means such as a mouse or a keyboard for inputting information necessary for operation, and a control means for controlling them.

The content attribute management means 31 and the user information management means 32 in the acquired content information management server 3 are implemented by using a database application such as so-called Oracle, which provides a database use interface using SQL or the like. It is possible.

The operation of this content information management system will be described below.

First, the user of the system is given a user ID uniquely given to the user in advance.
As a specific example of the user ID, for example, "UIDO
It can be a character string consisting of alphabetic characters or numbers such as "01".

The user can acquire the content ID of the content of interest at the user terminal 2, and the acquired content information is transmitted to the acquired content information management server 3 and at the same time, the user terminal. When the content is browsed in 2, the content ID corresponding to the browsed content and the operation information, which is the browsing date and time, are used as user information from the user information transmitting means 25 to the acquired content information management server 3 in the same manner. Sent. The user information is managed by the user information management means 32 of the acquired content information management server 3 for each user ID.
Further, the content ID managed by the acquired content information management server 3 can be browsed by the user terminal 2, and the content ID deleting means 26 can be used to browse and browse the corresponding content, if necessary. It is possible to delete a different content ID.

As a concrete environment for acquiring such a content ID, for example, a bookmark is added in the WWW system, or a barcode is printed on an advertisement, a poster, etc. In addition, in a digital broadcasting environment, etc., by pressing a button on the remote control while watching TV, the content I
Get D, and the desired content ID for the remote control
It is possible to assume that the acquisition conditions are set and automatically acquired. In this way, the user can easily acquire the content ID of the content relating to the information of interest.

On the other hand, in the content attribute management means 31 of the acquired content information management server 3, the content attribute which is the additional information of the content is created in advance by the content provider and is uniquely assigned to the content for each content ID. It is managed. Here, the content attribute means that the content ID system is different from the resource location of the corresponding content, either one or both of the valid period of the relevant content itself or the information obtained from this content and the update date and time of the relevant content. Is information including a resource location and one or more of a resource location of an icon image representing the corresponding content, a content name, and a comment. For specific examples of content IDs,
If it is the same as the resource location, then a general W
It can be a URL in the WW system, and if different, it can be a character string composed of alphabetic characters or numbers such as "CID0000001".

Further, as described above, the user information is changed to the user I
While managing for each D, the unnecessary content ID deleting unit 33 deletes the content ID determined to be unnecessary from the content IDs included in the user information corresponding to the designated user ID at a predetermined timing. here,
When the user inputs the user ID and logs in to the user terminal 2 at a predetermined timing, the acquired content information management server 3 receives the user ID from the user terminal 2 and corresponds to the received user ID. The following processing is performed for each content ID included in the user information.

First, the acquired content attribute management server 3 accesses the relevant content. Therefore, the unnecessary content ID deleting unit 33 includes an access error managing unit that accesses the corresponding content and confirms whether there is an access error. At this time, if an access error occurs,
When the occurrence frequency satisfies a preset condition while recording the occurrence date and time and referring to the past occurrence date and time, the unnecessary content ID deleting unit 33 determines the content ID.
Delete as unnecessary. Note that the preset condition is, for example, "access error occurs 10 times or more in a row in the past 7 days".

Next, the unnecessary content ID deleting means 33.
Searches the content attribute management means 31 and refers to the valid period information among the content attributes corresponding to this content ID. At this time, if the valid period has expired, this content ID is deleted as unnecessary.

Further, the unnecessary content ID deleting means 33.
Among the acquisition date and time and the update date and time in the content attribute, the elapsed time from the latest date and time to the present, and the elapsed time from the last access date and time to the present have passed the preset predetermined time, respectively. Further, the content ID whose access count has not reached the preset predetermined count is deleted as unnecessary. The preset predetermined time is, for example, “30 days”, and the predetermined number of times is “10 times”. It is also possible to set a predetermined time and the number of times according to the number of accesses of all users.

When the above process is executed for all the content IDs included in the user information and the content IDs judged to be unnecessary as a result are deleted from the user information, the user browses the acquired content IDs. In this case, only content IDs that can be considered valid or necessary can be browsed.

On the other hand, the unnecessary content ID deleting means 33 of the acquired content information managing server 3 has a predetermined period, which is confirmed by the content access managing means 34, for example, every certain period, apart from the login of the user. ,
Content I that was never accessed by any user
It is possible to delete D from all user information, and if the content ID is deleted due to the above access error, another content ID similar to all or some of the corresponding content attributes. Can be newly added. When providing this function, it is desirable that the content attributes include, for example, the name of the content provider, the type of content, and a plurality of keywords that appropriately represent the content.

In the provider terminal 4, the content attribute updating means 41 is used by the content provider to communicate with the acquired content information management server 3 as necessary, and the content attribute managing means 31 is newly provided with the content. ID
Add, update, delete and add, update content attributes,
It can be deleted. Therefore, the content provider can change the content attribute not only for the newly provided content but also for the already provided content, and the shortening or extension or expiration of the effective period of the content depending on the circumstances of the content provider. It is possible to easily change settings such as.

Regarding the preferred embodiment of the present invention, the content ID for the related Web content of the advertisement information
A simple first embodiment applied to the acquisition and management thereof will be described with reference to FIG.

First, the user ID "U" is given to the user.
ID001 ”is assigned, and the user terminal used by this user has a connection means to the Internet by wireless or wired and can cooperate with a television receiver,
A user of the type A who does not have a direct connection means between the fixed terminal type user terminal 2A of the content terminal capable of acquiring the content ID and the Internet via a server provided separately on the network 1 Assuming two terminals, a mobile terminal type B user terminal 2B, which can be indirectly connected to the Internet by connecting to the terminal and can acquire a content ID through scanning a barcode. . It should be noted that the content ID managed by the acquired content information management server 3 and the corresponding content can be browsed only from the type A user terminal 2A, and the browsed information is the operation history as the acquired content information management server 3
F will be sent.

Regarding the acquisition of the content ID,
The following environment is already provided.

The content ID is a URL in the WWW system. As an example of a specific content ID acquisition scene, for the type A user terminal 2A, if a button is pressed while watching a TV CM, that CM will be displayed. The URL of the Web page in which the related information is described, that is, the content ID is acquired via a predetermined server on the network 1 and stored in the acquired content information management server 3.

On the other hand, for the type B user terminal 2B, a bar code is printed on general advertisement leaflets, street posters, books, magazines, etc., and a web page in which related information is written by scanning the bar code. , The content ID is acquired and stored in the acquired content information management server 3.

Regarding the former, for the former, for example, in the server on the network 1, the content ID is managed based on the broadcast channel and the absolute time, and the current broadcast is performed by pressing the button on the user terminal 2A. It can be realized by transmitting the channel and the absolute time to the server and providing the corresponding content ID using this as a key.
Further, the latter can also be performed by the conventional barcode technology.

Therefore, the user, on a daily basis, acquires the content ID of the content of interest. By using the type A user terminal 2A while watching a TV commercial indoors, for example, the content ID of a CM related web page can be easily obtained, and the acquired content ID and its acquisition date and time are It is transmitted to the acquired content information management server 3 via the network 1. In the outdoors, type B
Content of related Web pages of information of interest from posters and magazines on street corners using the user terminal 2B of
D can be acquired and is transmitted to the acquired content information management server 3 via the network 1 by connecting to the type A user terminal 2A at home.

The content attributes provided by the content provider are stored in the content attribute storage means 31A as the valid period of the content itself or information obtained from it, the update date and time of the content, and the title of the content. Managed. User information is
In addition to the acquired content ID, the acquisition date and time of the content ID, the previous access date and time of the corresponding content, and the number of times of access are stored, and are stored and managed in the user information storage means 32A. An example of content attributes is shown in FIG. 3, and an example of user information is shown in FIG.

Under the above conditions, since the user browses the acquired content ID on the type A user terminal 2A, when the user logs in with the user ID "UID001", the acquired content information management server 3 uses the user ID. "U
Unnecessary content IDs are deleted from the content IDs managed by ID001 ".

First, the acquired content information management server 3 determines the user I input and transmitted by the user terminal 2A.
The user information corresponding to D "UID001" is referred to.
Next, for each content ID included in the referred user information, it is determined whether or not it is unnecessary, and the unnecessary content ID is deleted. In the present embodiment, the unnecessary content ID deleting means of the acquired content information management server 3 has the following three functions.
Only step.

Step 1: When the corresponding content is accessed, and when an access error occurs at this time, the date and time of occurrence is recorded, and the date and time of occurrence in the past are referred to. Delete the content ID as unnecessary. The condition at this time is that "access errors occur 5 times or more consecutively in the last 7 days"
And Note that, at this time, an example of information regarding an access error to the relevant content, which the acquired content information management server 3 holds, is shown in FIG.

Step 2: Confirm the valid period. The current date and time is "September 25, 2001", and the expiration date of the valid period of the content ID to be confirmed is "September 24, 2001".
If it is a previous version, delete it from the user information.

Step 3: Of the acquisition date and time and the update date and time in the relevant content attribute, the elapsed time from the latest date and time to the present and the previous access date and time to the relevant content included in the user information until the present. The elapsed time is
Content IDs that have passed a predetermined time set in advance and the number of accesses has not reached the predetermined number set in advance are deleted as unnecessary. The predetermined time and the number of times are set to "30 days" and "10 times" as in the above-mentioned example. Further, regarding the content that has not been accessed even once, the last access date and time is set as “not accessed” and is not the target of the processing.

Unwanted content ID according to the rules of the unnecessary content ID deleting means in steps 1 to 3.
FIG. 6 shows the user information as a result of deleting the. The content ID for which an access error occurred in step 1
Is "http: //xxx/dress.html"
Only tried. In this way, the user does not necessarily have to positively organize the content IDs even when the number of acquired content IDs becomes very large. By considering the operation history that is considered to reflect the interest of the user and deleting the content ID that is considered unnecessary, the user can efficiently browse the content ID.

As the second embodiment other than the above, the contents provider terminal 4 is the same as the second embodiment.
Then, by accessing the content attribute management means of the acquired content information management server 3 from the content provider terminal 4 and updating the content attribute, the service is provided according to the reaction of the user to the content provided by the content provider. It is possible to reflect that the period is extended or shortened.

The third embodiment is the same as the first embodiment.
In addition, apart from the time when the user logs in to the user terminal 2, the content ID that has not been accessed by any user for a predetermined period is periodically deleted from all the user information. As a specific example, the acquired content information management server 3 checks the access count of each content every three months, and deletes the content IDs that have not been accessed for three months from all the user information. That is.

As the fourth embodiment, the first embodiment described above is used.
The setting of the predetermined time and the number of times in step 3 in step 3 is not based on "30 days, 10 times" in advance, but is determined based on the total number of users accessing the content. Is. As a specific example,
If the number of accesses in the past month is less than 1000,
"5 times for 20 days", if there are 1000 or more, "30
Set a stage such as "10 times a day" and create a table so that the number of accesses and the condition uniquely correspond to each other. It is also possible to define numerically like 1.

As the fifth embodiment, the first embodiment described above is used.
In step 1 in step 1, another content ID most similar to all or some of the content attributes of the deleted content ID is added to the user information. As a specific example, “provider name”, “product type”, and “product name” are added to the content attribute, and similar contents are determined with reference to these. I can give you.

Content ID "h" in the first embodiment
ttp: /// xxx / dress. In the content attribute of "html", "provider name: XX closing",
"Product type: Party dress", "Product name: DR
Assuming that "S-01" is added, "provider name: XX closing" and "product type:" in the content attribute.
Content ID "http: // xxx /" to which "Party dress" and "Product name: DRS-02" are added
dress2. It is assumed that there is more "html". In such a situation, the content ID "http: // xxxx /
dress. When “html” is deleted from the user information, a content ID “http: ///
xxx / dress2. html "is newly added. The similar determination method is not limited in the present invention, and whether or not it is newly added can be set in the user terminals 2A and 2B. Is desirable.

[0067]

As described above, according to the content information management system and the acquired content information management server of the present invention, when managing the content ID acquired by the user, the acquired content information management server on the network manages it, which is unnecessary. By deleting such a content ID, the user does not need to actively manage the content ID by himself and can efficiently manage and browse the content ID, and as a result, promote acquisition of a new content ID. I think I can do it.
