As shown in the figure, the content providing system 10 includes a server device 110, a plurality of client devices 120, and a network 130. The server device 110 provides content to the client device 120. The client device 120 uses content in accordance with a user operation, and acquires new content from the server device 110 as necessary. In the present embodiment, the client device 120 is, for example, a personal computer and is used by a predetermined user. The network 130 is, for example, the Internet, and connects the server device 110 and the client device 120 so that they can communicate with each other.

  In the present embodiment, “content” refers to a program executable by the client device 120. In the present embodiment, the content includes attribute information representing the attribute of the content. The attribute information is various pieces of information representing the characteristics of the content, and details thereof will be described later.

  FIG. 2 is a block diagram illustrating a configuration of the server device 110. As shown in the figure, the server device 110 includes a control unit 111, a storage unit 112, and a communication unit 113. The control unit 111 includes an arithmetic device such as a CPU (Central Processing Unit) and a memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and executes a stored program to execute the stored program. Control the behavior. The storage unit 112 includes a storage device such as an HDD (Hard Disk Drive), and stores data used by the control unit 111 and a plurality of contents supplied to the client device 120. The plurality of contents stored in the storage unit 112 are hereinafter collectively referred to as “content group”. The communication unit 113 includes an interface connected to the network 130, and transmits and receives data.

  The storage unit 112 stores content feature information and user feature information as data used by the control unit 111. The content feature information is information for classifying content according to a predetermined number of patterns (types). The content feature information exists for each content constituting the content group and is associated with the corresponding content. The user feature information is information that represents the user in the same pattern as the content feature information. The user characteristic information is information that may exist for each of the client devices 120 that communicate with the server device 110, and is associated with the corresponding client device 120 (ie, a user). The user characteristic information is generated and stored by the server device 110.

  FIG. 3 is a schematic view illustrating the structure of content feature information. As shown in the figure, the content feature information includes a content ID, pattern information, and level information. The content ID is information for uniquely identifying the content, and is, for example, the name of the content. The content feature information is associated with the corresponding content by the content ID. The pattern information is information indicating a pattern that can be given to the content, and the level information is information indicating the level (degree) of the corresponding pattern information. The pattern information and the level information are paired information, and the content feature information includes the same number of pairs as the number of pattern information. The level information is information indicating the degree at a predetermined stage (“10” in the present embodiment).

FIG. 4 is a diagram illustrating pattern information in the present embodiment. In the figure, “pattern A” is pattern information representing the “newness” of the content. That is, the higher the level of “Pattern A”, the newer the sales start time of the content, and the lower the level of “Pattern A”, the higher the level of “Pattern A”. “Pattern B” is pattern information representing the “cheap” of the content. That is, the higher the level of “Pattern B”, the lower the content, and the lower the level of “Pattern B”, the higher the content. “Pattern C” is pattern information indicating “cheap” of content. That is, the higher the level of “Pattern C”, the lower the price of the content, and the lower the level of “Pattern C”, the higher the content. It represents that.
In addition, as illustrated in the figure, it is possible to determine a pattern from various viewpoints such as popularity of content, safety, and ease of operation.

The pattern information and level information of each content is specified by the attribute information of the content.
FIG. 5 is a diagram illustrating content attribute information. As shown in the figure, the attribute information includes “content ID”, “category”, “sales date”, “list price”, “sales price”, “popular ranking”, “seller”, “function”, “ UI evaluation ”and the like are included.

  The “content ID” is information for uniquely identifying the content, and is the same information as that included in the content feature information. The “genre” is information representing a category (that is, a category) when the content is classified according to usage. “Sales date” is information indicating the date on which the content is sold, and is information for specifying “newness” of the content. The “list price” is information representing the list price of the content, and the “sales price” is information representing the actual sales price (after discount) when the content is discounted. The “list price” is information that specifies the “cheap” of the content, and the “list price” and “sales price” are information that identifies the “cheap” of the content. “Popularity ranking” is information indicating the ranking of the content determined by the sales amount and the sales quantity, and is information for specifying “popularity” of the content. “Seller” is information that represents an individual or a corporation that sells the content, and is information that specifies the “safety” of the content. For example, if the seller is a well-known corporation, the content is relatively safe, and if the seller is an anonymous individual, the content can be said to have a relatively high possibility of causing an unexpected malfunction. “Function” is information indicating the function of the content, and is information for specifying “operability” of the content. For example, when the content is multifunctional, it can be said that the operation is not relatively easy. “UI evaluation” is information indicating evaluation by a user or a seller regarding the UI (user interface) of the content, and is information for specifying “coolness / cuteness” of the content.

  FIG. 6 is a block diagram illustrating the configuration of the client device 120. As shown in the figure, the client device 120 includes a control unit 121, a storage unit 122, a display unit 123, an operation unit 124, and a communication unit 125. The control unit 121 includes an arithmetic device and a memory, and controls the operation of the client device 120 by executing a stored program. The storage unit 122 stores data used by the control unit 121 such as content. The display unit 123 includes a display device such as a liquid crystal display, and displays an image according to the control of the control unit 121. The operation unit 124 includes an input device such as a mouse and a keyboard, and supplies information representing a user operation to the control unit 121. The communication unit 125 includes an interface connected to the network 130 and transmits and receives data.

  The configuration of the content providing system 10 is as described above. Under this configuration, the client device 120 executes content stored in advance based on a user operation. In addition, the client device 120 acquires new content from the server device 110 as appropriate. The client device 120 acquires the content in a first mode in which the content specified by the operation by the user is acquired and in a second mode in which the content notified by the server device 110 is acquired. In the first mode, for example, the client device 120 displays a list of content groups on the display unit 123 and acquires the content selected by the user from the storage unit 112 of the server device 110. In the second mode, based on the usage history of each client device 120, the server device 110 notifies the client device 120 of a suitable content and acquires it. Below, this 2nd aspect is demonstrated in detail with reference to a flowchart etc.

  FIG. 7 is a flowchart illustrating processing executed by the client device 120. FIG. 8 is a flowchart showing processing executed by the server apparatus 110. The second aspect described above is realized by these operations of the server device 110 and the client device 120, and is started when the operation of the client device 120 is performed.

  As shown in FIG. 7, first, the control unit 121 of the client device 120 acquires a history of content related to user usage (step Sa1). Here, the content related to the use of the user may be, for example, content that can be used by the user (that is, content stored in the client device 120 of the user), It may be content actually executed in a week). In the former case, it does not matter whether the content is actually executed or not, but only the actually executed content may be the content related to the use of the user. Here, the history acquired by the control unit 121 is hereinafter referred to as “use history”. The usage history is information describing content related to user usage, and is stored in the storage unit 122, for example.

  Next, the control unit 121 transmits the acquired usage history to the server device 110 (step Sa2). Thereafter, the control unit 121 waits until content is notified from the server device 110 (step Sa3). The server apparatus 110 performs the process shown in FIG. 8 in order to specify the content notified to the client apparatus 120 and the notification mode.

  As shown in FIG. 8, the control unit 111 of the server device 110 receives (that is, acquires) the usage history transmitted from the client device 120 (step Sb1). The control unit 111 identifies the content described in the usage history, and extracts content feature information of the identified content (step Sb2). That is, at this time, the control unit 111 selectively specifies content related to the use of the user, and extracts and acquires content feature information of the content.

  Based on the extracted content feature information, the control unit 111 generates user feature information representing the usage mode of the user's content corresponding to the received usage history (step Sb3). The control unit 111 generates user feature information according to the extracted content feature information pattern information and level information.

  A method for generating user feature information will be described with a specific example. Now, it is assumed that there are two contents represented by the usage history, “content a” and “content b”, and the respective content feature information is as shown in FIG. At this time, the corresponding user characteristic information includes “pattern A” level information “6 (= (10 + 2) / 2)”, “pattern B” level information “3 (= (2 + 4) ÷ 2)”, The level information of “Pattern C” is “1 (= (1 + 1) ÷ 2)”. That is, the user feature information is obtained by using an arithmetic average of level information corresponding to the same pattern information of the user feature information as the value of the level information.

  Returning to the description of FIG. After generating the user feature information, the control unit 111 compares it with the content feature information of each content included in the content group (step Sb4). At this time, the content stored in the client device 120 of the user is excluded from the content to be compared. This is because the content already available to the user does not need to be notified. The control unit 111 temporarily stores the comparison result.

  The control unit 111 gives identification data to the content feature information of each content according to the comparison result of step Sb4. Here, “identification data” refers to information for identifying a notification mode of content. In this embodiment, it is assumed that there are four types of identification data, “1”, “2”, “3”, and “4”. The control unit 111 assigns identification data as follows.

  When generating the identification data, first, the control unit 111 determines whether or not the degree of similarity with the user feature information is equal to or higher than the first degree (step Sb5). In addition, when the degree of similarity with the user feature information is greater than or equal to the first degree, the control unit 111 determines whether the degree of similarity with the user feature information is greater than or equal to the second degree ( Step Sb6). Here, the “first degree” and the “second degree” refer to information including a predetermined numerical value indicating the degree of similarity.

In the present embodiment, the “first degree” represents a difference between the level information of the user feature information and the level information of the corresponding content feature information, and the value of the difference is “3”. That is, each value of the level information indicated by the content feature information is C _i (where i = 1, 2,..., N, where n is the number of pattern information), and each value of the level information corresponding to the user feature information. When U _i is U _i , when U _i −2 ≦ C _i ≦ U _i +2 is satisfied for all i, the content feature information is more similar to the user feature information than the first degree.

  FIG. 10 is a diagram showing level information in a so-called radar chart. Here, the degree of similarity between the user feature information and the content feature information will be described using the example of FIG. Now, as shown in FIG. 10A, it is assumed that each level information of the user characteristic information is “5” for each of the patterns A to C. Further, as indicated by solid lines in FIGS. 10B, 10C, and 10D, the level information of a certain content c is “6”, “4”, and “5” for each of the patterns A to C. Each level information of a certain content d is “7”, “5”, “4” for each of the patterns A to C, and each level information of a certain content e is “9”, “ 5 ”and“ 5 ”. The broken line indicates the level information of the user feature information. At this time, the contents c and d are determined to be similar to the user feature information of FIG. 10A to the first degree or more because the difference in level information of each pattern is “2” or less. On the other hand, since the difference in level information of the pattern A is “4”, the content e is determined not to be similar to the user feature information in FIG.

  In the present embodiment, the “second degree” represents a difference between the level information of the user feature information and the level information of the corresponding content feature information, and the value of the difference is “1”. That is, the fact that the content feature information and the user feature information are similar to the second degree or more indicates that these pieces of information are similar to each other at a higher degree than the first degree. For example, in the case of the example in FIG. 10, the content similar to the user feature information more than the second degree is only the content c, and the content d and e are the user feature information and the second content in FIG. It is judged that it is not similar to more than the degree.

  Returning to the description of FIG. The control unit 111 determines whether or not the content feature information whose degree of similarity with the user feature information is greater than or equal to the second degree is completely matched with the user feature information (step Sb7). That is, at this time, the control unit 111 determines whether or not the level information of each pattern of the content feature information matches the level information of each pattern of the user feature information. When there is content feature information that completely matches the user feature information, the control unit 111 assigns “1” as identification data to the content feature information (step Sb8).

  In addition, when there is content feature information that does not completely match the user feature information and the degree of similarity with the user feature information is equal to or higher than the second degree, the control unit 111 includes identification information in the content feature information. “2” is assigned (step Sb9). Further, when there is content feature information whose degree of similarity with the user feature information is equal to or higher than the first level and not higher than the second level, the control unit 111 sets “3” as identification data in the content feature information. (Step Sb10). When there is content feature information whose degree of similarity with the user feature information is not equal to or higher than the first degree, the control unit 111 gives “4” as identification data to the content feature information (step Sb11).

  When the identification data is assigned to each content feature information, the control unit 111 determines the notification mode of each content according to the identification data. The control unit 111 determines the value of the identification data given to each content feature information (step Sb12), and changes the mode of notification according to the determination result.

  When the identification data is “1”, the control unit 111 acquires content corresponding to the content feature information to which the identification data is assigned, and requests to install the content (hereinafter referred to as “installation request”). At the same time, this is transmitted to the client device 120 (step Sb13). Further, when the identification data is “2”, the control unit 111 acquires a content corresponding to the content feature information to which the identification data is assigned, and requests to select whether or not to install the content ( This is hereinafter referred to as “installation selection request”) and transmitted to the client device 120 (step Sb14). When the identification data is “3”, the control unit 111 requests to select whether to download the content corresponding to the content feature information to which the identification data is assigned (hereinafter referred to as “download selection request”). Is transmitted to the client device 120 (step Sb15). When the identification data is “4”, the control unit 111 does not perform processing related to the content corresponding to the content feature information to which the identification data is assigned (step Sb16).

  That is, when the identification data is “1” or “2”, the control unit 111 notifies the client device 120 of the content by transmitting the corresponding content, while the identification data is “3” or “4”. ", The corresponding content is not transmitted to the client device 120. Further, when the identification data is “3”, the control unit 111 does not transmit the corresponding content itself, but performs notification of the content.

  Returning to the description of the client device 120 in FIG. When receiving the content notification, the control unit 121 of the client device 120 performs processing according to the request from the server device 110. When receiving the content accompanied by the installation request, the control unit 121 acquires the content and executes the installation, thereby making the content usable (steps Sa4 and Sa5). In addition, the control unit 121 notifies the user of the installed content (step Sa6). At this time, for example, the control unit 121 notifies the user of the content by causing the display unit 123 to display the name of the content and a message indicating that the content has been installed.

  In addition, when receiving the content accompanied by the installation selection request, the control unit 121 acquires the content and causes the user to select whether to install the content (steps Sa7 and Sa8). At this time, for example, the control unit 121 displays the name of the content on the display unit 123 to notify the user of the content and causes the display unit 123 to display a screen for selecting whether to install the content. When the user selects to install the content, the control unit 121 installs the content (steps Sa9 and Sa10).

  In addition, when receiving a download selection request, the control unit 121 causes the user to select whether or not to download content corresponding to this request (steps Sa11 and Sa12). At this time, for example, by displaying the name of the content on the display unit 123, the control unit 121 notifies the user of the content and causes the display unit 123 to display a screen for selecting whether to download the content. When the user selects to download content, the control unit 121 downloads the content from the server device 110 and installs it according to an instruction from the user (steps Sa13, Sa14, Sa15).

As described above, according to the content providing system 10 of the present embodiment, the server device 110 generates user feature information based on the user usage history. Therefore, the user only needs to use the content as necessary, and does not need to register his / her attributes or the like in advance.
For example, a user who often uses new content is considered a user who is interested in the new content and has a tendency to actively use the new content. For such a user, the server device 110 notifies the content when a new content is added to the content group. On the other hand, for users who do not frequently use new content and often use existing content, no special notification is made even if new content is added to the content group. As described above, according to the content providing system 10 of the present embodiment, content suitable for each user is notified even if the user does not perform a special operation.

  Further, according to the content providing system 10 of the present embodiment, the user characteristics (user characteristic information) and the content characteristics (content characteristic information) are compared based on the pattern information and the level information. As a result, the content providing system 10 according to the present embodiment can easily classify users and contents and compare them. Also, by classifying user feature information and content feature information with the same pattern information, it is possible to compare the two relatively easily even when there are a wide variety of patterns.

  Furthermore, according to the content providing system 10 of the present embodiment, the content can be notified in a plurality of modes according to the degree of similarity between the user feature information and the content feature information. For example, content that has a very high degree of similarity with the user feature information is installed without the user's confirmation by the client device 120, so that it is possible to reduce operations until it becomes available. Yes. In addition, for example, it is possible to expect an effect of suppressing unnecessary downloads by changing whether the user is notified before downloading or not after downloading depending on the degree of similarity.

[Second Embodiment]
FIG. 11 is a diagram showing a configuration of a content providing system according to the second embodiment of the present invention. As shown in the figure, the content providing system 20 includes a server device 210, an information processing device 220, a plurality of client devices 230, a first network 240, and a second network 250. The server device 210 has substantially the same configuration as the server device 110 of the first embodiment, and notifies the content, but differs from the first embodiment in that the content notification destination is the information processing device 220. The information processing apparatus 220 is a so-called multi-function machine having printer, scanner, and facsimile functions. In this embodiment, it is this information processing apparatus 220 that uses the content notified from the server apparatus 210. The client device 230 is a terminal used by each user, and is a terminal that transmits a print job or the like to the information processing device 220. The first network 240 is, for example, the Internet, and connects the server apparatus 210 and the information processing apparatus 220 so that they can communicate with each other. The second network 250 is, for example, a LAN (Local Area Network), and connects the information processing apparatus 220 and the client apparatus 230 so as to communicate with each other.

  FIG. 12 is a block diagram illustrating a configuration of the information processing apparatus 220. As shown in the figure, the information processing apparatus 220 includes a control unit 221, a storage unit 222, an operation unit 223, an information processing unit 224, and a communication unit 225. The control unit 221 includes an arithmetic device and a memory, and controls the operation of the information processing device 220 by executing a stored program. The storage unit 222 stores data used by the control unit 221 such as content and usage history. The operation unit 223 includes a touch panel display and buttons, and accepts user operations. The operation unit 223 generates an operation signal corresponding to the user operation and supplies the operation signal to the control unit 221. The information processing unit 224 includes an image reading device that reads an image and an image forming device that forms an image on paper, and realizes functions of a printer, a scanner, and a facsimile. The communication unit 225 includes an interface connected to the first network 240 and the second network 250, and transmits and receives data.

In addition to using the information processing apparatus 220 via the second network 250, the user can use the information processing apparatus 220 by directly operating the operation unit 223. The information processing apparatus 220 identifies the user when the user starts using the information processing apparatus 220. For example, the control unit 221 performs a so-called authentication process in which a list of user names is displayed on the display of the operation unit 223 to prompt the user to select or to input a user name and a password.
Further, the information processing apparatus 220 can obtain a new function or update an existing function by installing a new content in the content group.

  The information processing apparatus 220 of this embodiment can execute the same processing (see FIG. 7) as the client apparatus 120 of the first embodiment. The information processing device 220 acquires a usage history for each user who operates, and transmits the usage history to the server device 210. When the server device 210 receives the usage history, the server device 210 generates user feature information in the same manner as the server device 110 of the first embodiment (see FIG. 8), and determines a notification mode for each user. And the information processing apparatus 220 will perform the process regarding notification (step Sa4-Sa15), if the information regarding the content which should be notified is acquired and a corresponding user starts operation.

  At this time, the information processing apparatus 220 performs notification according to each user by changing the display on the operation unit 223 for each user. For example, the information processing apparatus 220 displays only content that has a higher degree of similarity with the user feature information of the user among the newly available content, or displays all the newly available content. The content having a higher degree of similarity with the user characteristic information of the user is displayed in a mode (such as emphasis) different from other content.

As described above, according to the content providing system 20 of the present embodiment, content suitable for each user is notified to the information processing apparatus 220. The user can appropriately select the notified content and install it as necessary. According to the information processing apparatus 220 of the present embodiment, when each user performs an operation, the user is notified of the content suitable for each user. Therefore, among the newly available content, the user is more necessary. It is possible to selectively notify only content that is highly likely to exist. This notification method is particularly effective when the amount of newly available content is large. In particular, in a so-called copying machine or the like, the display area of the display is often relatively limited, and such an individual selective notification method is effective.
Note that content installed by each user may be available only to the user, or may be available to all users after installation.

[Modification]
The present invention can be implemented in a form different from the above-described embodiment. The present invention can also be implemented in the following forms, for example. Further, the following modifications may be combined as appropriate.

In the present invention, the content feature information and the user feature information are not limited to the above-described formats. In the present invention, the content feature information and the user feature information may be in any format as long as the degree of coincidence or similarity between them can be determined, but in order to facilitate the comparison between the two, It is desirable that it is represented by a similar pattern.
Further, the user characteristic information may be information corresponding to the usage frequency of the user's content.

  In the first embodiment described above, when the content feature information and the user feature information are compared, the degree of similarity between the two is compared. However, the degree of coincidence between the two may be compared. For example, when the number of pattern information with matching level information is larger, a process for reducing the value of the identification data may be performed.

The server device according to the present invention may generate user characteristic information for each “category” described above. That is, the server device according to the present invention may be configured to generate different user characteristic information for a certain category and another category. In this case, the server device is configured to compare the user feature information having the same category with the content feature information.
According to such a configuration, even if a certain user's pattern is different between a certain category and another category, it is possible to notify a suitable content in each category.

  In the present invention, the content may be information other than the program. In the present invention, the content may be, for example, advertisement information describing the content of the product or an advertisement. Further, when the content is advertisement information, “use” of the content is “consent” to “view”. In such a case, a method for increasing or decreasing the amount of content can be cited as a method for changing the content notification mode. For example, for content with a higher degree of matching or similarity with user feature information, more information is notified to the user, while for content with a lower degree of matching or similarity with user feature information, the user is notified. The amount of information to be performed may be limited. As a mode of such restriction, for example, the image data amount may be reduced by deleting the image or reducing the resolution of the image, or only important information such as a headline is notified. You may make it do.

Part of the processing executed by the server device 110 in the first embodiment described above can also be executed by the client device 120. For example, the server apparatus includes means for storing a content group, means for acquiring content feature information, means for generating user feature information, and means for determining the content to be notified to the user and its notification mode. It is good also as a structure with which. That is, the client device according to the present invention includes means for acquiring content information, means for specifying content (use history) related to user usage, means for generating user feature information, content to be notified to the user, and It may be configured to include means for determining a notification mode and means for notifying the user of content.
Similarly, the server device 110 may execute part of the processing executed by the client device 120 in the first embodiment. Furthermore, the second embodiment described above can be modified in the same manner.

  In the second embodiment described above, the device that uses the content may be changed from the information processing device 220 to the client device 230. That is, the information processing device 220 may be used as a relay device that relays information exchange between the server device 210 and the client device 230. In this case, the information processing apparatus 220 transmits content or the like to the client apparatus 230 via the second network 250.
