Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information processing apparatus and method, a program, and a recording medium, and more particularly, to an information processing apparatus and method for recommending content closer to the user's interest based on interest data reflecting the user's intention, The present invention relates to a program and a recording medium.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a method of recommending a television program (content) or the like, for example, an initial interest registration method, a viewing history use method, a collaborative filtering method, and the like exist.
[0003]
In each case, as original data, electronic program guide (EPG: Electronic Program Guide) or program information (program metadata) on the Web or the like is used, and acquisition of user preference data to be matched with the information is used. The methods are classified into the above three methods.
[0004]
In the initial interest registration method, at the start of use, for example, the user registers a favorite program category (drama, variety, etc.), a favorite genre name (drama, music, etc.), a favorite talent name, and the like. Using the registered information as a keyword, matching is performed with the program metadata to obtain a program name to be recommended.
[0005]
In the viewing history utilization method, every time a user views a program, program metadata relating to the program is accumulated, and when a predetermined amount of viewing history (program metadata) is accumulated, the viewing history is analyzed and recommended. Get the name of the program to be done. In place of the viewing history, for example, in an apparatus for recording on a hard disk drive, an operation history such as recording reservation or recording start by a user can be used. In this case, it is possible to acquire not the vague program but information reflecting the user's interest more.
[0006]
In the collaborative filtering method, matching is performed between a user's viewing (operation) history and another user's viewing history, and a viewing history of another user whose viewing history is similar to that of the user is acquired. Then, among the programs viewed by other users having similar viewing histories (similar preferences), the program names that the user has not yet viewed are acquired and recommended.
[0007]
By using the program recommendation method as described above, it is possible to recommend a program that the user seems to be interested in.
[0008]
However, in the above-described program recommendation method, the user's interest is extracted from the program metadata (that is, a biased interest related to a TV program is acquired). A name that is easy to communicate is used, and a similar program is recommended.
[0009]
Therefore, the applicant has proposed a method in which a user inputs a predetermined item to create a personal profile of the user and recommend content based on the profile (for example, see Patent Document 1).

FIG. 4 is a block diagram illustrating a functional configuration example of the CPU 51 of FIG. 2 or the CPU 71 of FIG. In this example, there are provided a user information acquisition unit 101 for acquiring user preference information from initially registered information and the like, and an interest extraction unit 102 for extracting interest data based on information acquired by the user information acquisition unit 101. I have. The extracted interest data is stored in the HDD 78, for example.
[0058]
Further, the interest data extracted by the interest extraction unit 102 is transferred to the related information search unit 103, and the related information search unit 103 presents related information based on the interest data. The related information includes program information on an electronic program guide (EPG) or on the Web, on-air program information, information on contents acquired via the network 5, and the like. Further, the related information database creating unit 105 acquires metadata of the EPG and the content, classifies the metadata as related information corresponding to predetermined interest data, and stores the related information in, for example, the HDD 78 as a database.
[0059]
The related information searched by the related information search unit 103 is output to, for example, the television receiver 3 by the related information presentation unit 104. The evaluation input unit 105 receives, for example, an input of a user's evaluation on the presented related information via the input unit 76. The user input is fed back to the interest extraction unit 102 via the evaluation input unit 105.
[0060]
The interest data presentation unit 107 presents interest data to the user. The interest data is data indicating how much the user is interested in what, and is composed of a plurality of attributes such as “genre” and “region” and the importance of the attribute. The interest evaluation input unit 108 receives an input of a user's evaluation with respect to the presented interest data, and the received evaluation result is fed back to the interest extraction unit 102 to change the interest data.
[0061]
Next, an information presentation process of the HDD recorder 2 will be described with reference to FIG. In step S1, the interest extraction unit 102 acquires user preference information from information registered in the initial stage, and extracts interest data. At this time, the interest data with the highest importance is extracted from the interest data that is initially registered. The importance level is initially set to a standard value in advance, but is updated in accordance with the usage status of the user (the processing of step S46 in FIG. 7 described later).
[0062]
In step S2, the related information search unit 103 executes a related information search process described later with reference to FIG. Thereby, the related information corresponding to the interest data is presented to the user. In step S3, the evaluation result input unit 105 receives an input of the user's evaluation for the presented related information. For input of the evaluation, for example, a GUI for selecting an evaluation (for example, “OK” or “NG”) of the related information presented on the monitor of the television receiver 3 is displayed, and the user operates the input unit 76. It is done by doing.
[0063]
In step S4, the evaluation result input unit 105 determines whether or not the evaluation of the user is “OK”. If it is determined that the evaluation is not “OK”, the process returns to step S1, and another interest data (For example, interest data having the second highest importance) is extracted, and the subsequent processing is repeatedly executed. If it is determined in step S4 that the evaluation is “OK”, the process ends.
[0064]
In this way, the related information is presented to the user, and the content is recommended.
[0065]
Next, the related information search process in step S2 in FIG. 5 will be described with reference to FIG. In step S21, the related information search unit 103 acquires the interest data generated by the interest extraction unit 102. In step S22, the related information search unit 103 searches the related information database for related information corresponding to the interest data. In step S23, the related information search unit 103 determines whether there is matching related information, that is, whether or not related information corresponding to the interest data has been searched.
[0066]
When it is determined in step S43 that there is matching related information, the process proceeds to step S24, and the related information search unit 103 outputs the related information to the monitor of the television receiver 3-1 and presents it to the user. On the other hand, when it is determined in step S23 that there is no matching related information, the process proceeds to step S25, and the related information search unit 103 outputs “no search result” to the monitor of the television receiver 3-1.
[0067]
In this way, the related information corresponding to the interest data is retrieved and presented to the user.
[0068]
The above-described interest data can be stored for each user or for each device. For example, when the user A and the user B use the HDD recorder 2-1 and the HDD recorder 2-2, the database of the interest data of the user A in the HDD recorder 2-1 and the database of the user B in the HDD recorder 2-1. It is possible to create a database of interest data, a database of interest data of user A in HDD recorder 2-2, and a database of interest data of user B in HDD recorder 2-2.
[0069]
In the above description, an example in which the interest data is generated in the HDD recorder 2 and the related information is presented to the user has been described. However, the interest data is also generated in another device, and the related information is presented to the user. For example, in the personal computer 1, interest data is generated and stored based on the content of the transmitted / received e-mail, the content of the browsed WWW page, and the related information is presented based on the interest data. You.
[0070]
Furthermore, interest data stored in a certain device (for example, the HDD recorder 2-1 or 2-2) is transmitted to another device (for example, the server 6), and a plurality of interest data are collectively stored, or different interest data is stored. You can also merge data.
[0071]
The display process of the interest data will be described with reference to FIG. This processing is executed, for example, in the personal computer 1 or the HDD recorder 2 based on an instruction from the user.
[0072]
In step S41, the interest data presentation unit 107 determines whether display of interest data has been instructed, and waits until it is determined that display has been instructed. For example, the display instruction may be given by the user operating the input unit 76 based on a GUI displayed on the monitor of the television receiver 3-1. The operation may be performed by operating a remote commander (hereinafter, referred to as a remote controller) attached to the John receiver 3-1.
[0073]
In step S42, interest data presentation section 107 accepts input of a user ID and a password. The user ID is a number for identifying the user, and the password is used to authenticate the user. The user ID and the password are registered in advance in, for example, the storage unit 59 of the server 6, and each device connected to the network 5 refers to the registered contents and checks that the entered user ID and password are valid. Can be confirmed. The input of the user ID and the password may be performed by the user operating the input unit 76, or the user may operate a remote commander (hereinafter, referred to as a remote controller) attached to the television receiver 3-1. The operation may be performed by performing an operation.
[0074]
In step S43, the interest data presentation unit 107 determines whether or not the input user ID and password are valid. If it is determined that they are valid, the process proceeds to step S44, and FIG. An interest data display process, which will be described later with reference to FIG. Thereby, the interest data is presented to the user.
[0075]
Here, the interest data display processing in step S44 in FIG. 7 will be described with reference to FIG. In step S61, the interest data presentation unit 107 acquires interest data corresponding to the user ID. For example, when the user ID input in step S42 in FIG. 7 is the user ID of the user A, the interest data of the user A is acquired in step S61.
[0076]
In step S62, the interest data presentation unit 107 displays the interest data on, for example, the monitor of the television receiver 3-1. FIGS. 9 and 11 show examples of interest data displayed at this time. First, a screen as shown in FIG. 9 is displayed. As described above, the interest data is composed of a plurality of attributes and the importance of the attributes. In this example, an attribute list 121 displaying a list of attributes and a list of values of the importance of each attribute are shown. The personal interest data 122 is displayed.
[0077]
The attribute list 121 shows a list of attributes constituting the interest data. In this example, the genre (1) is documentary (1-1), sports (1-2), information (1-3),.・ Is displayed. Also, as the region (2), overseas Asia (2-1), overseas Europe (2-2), overseas North America (2-3),... Are displayed.
[0078]
The personal interest data 122 shows a list of importance values of the respective attributes for the individual (in this case, the user A). The importance is a value indicating the level of interest of the user in the attribute. In this example, the value of the importance corresponding to the attribute 1-1 (documentary) is 0.61, and the attribute 1-2 (sports) ) Is set to 0.11, and the value of the importance corresponding to the attribute 1-3 (information) is set to 0.45.

At this time, a plurality of attributes of interest data may be summarized and displayed. FIG. 10 is a diagram showing an example of interest data displayed at this time. In the attribute list 121 of FIG. 10A, unlike FIG. 9, the incident (1-1-1) and the history (1-1-2) are displayed as the lower attributes of the documentary (1-1). Baseball (1-2-1) and soccer (1-2-2) as lower attributes of (1-2), and the United States (1-3-1) and Europe ( 1-3-2) is displayed. In addition, the personal interest data 122 in FIG. 10A includes attributes 1-1-1, 1-1-2, 1-2-1, 1-2-3, 1-3-1, and 1-3-2. The corresponding importance values are described.
[0080]
Here, attribute 1-3-1 (US) and attribute 2-2 (overseas United States) in FIG. 10A are one attribute 1-3-1 (this is attribute 1-3-1 (US) in FIG. 10A). 10A is a new attribute), and the attribute 1-3-2 (Europe) and the attribute 2-2 (foreign Europe) in FIG. 10A are one attribute 1-3-2 (this is shown in FIG. 10A). , Which is a new attribute different from the attribute 1-3-2), and is displayed as shown in FIG. 10B. The attributes 2-2 and 2-3 are not displayed in the attribute list 121 of FIG. 10B, and importance values corresponding to the attributes 2-2 and 2-3 are described in the personal interest data 122 of FIG. 10B. It has not been.
[0081]
In this case, the importance values (0.25 and 0.31) and the attributes 2-3 and 2-2 corresponding to the attributes 1-3-1 and 1-3-2 of the personal interest data 122 in FIG. For example, for the values (0.88 and 0.69), the average value is calculated, and the importance value (0 .0) corresponding to the attributes 1-3-1 and 1-3-2 of the personal interest data 122 in FIG. 57 and 0.50). In this way, attributes of a plurality of interest data that exist in FIG. 10A are put together and displayed as shown in FIG. 10B.
[0082]
A screen as shown in FIG. 11 is displayed as a child screen of the screen shown in FIG. This screen displays the details of the personal interest data 122, and displays a value of importance corresponding to each attribute and a symbol (* in the figure) indicating the magnitude of the value. The larger the value, the more the symbol “*” is displayed. By displaying in this manner, the user A has a high interest in the documentary (1-1) in the genre (1) with respect to his / her interest data. It can be seen that in the region (2), interest in overseas North America (2-3) is high.
[0083]
Further, instead of the screen as shown in FIG. 11, a screen as shown in FIG. 12 may be displayed. In this case, the value indicating the importance of each attribute is patterned, and the pattern corresponding to the numerical value is displayed as a concept. For example, if the importance value is from 0.00 to 0.24, it is "almost not interested", if it is from 0.25 to 0.49, it is "not very interested", and from 0.50 to 0. Patterns up to 74 are patterned as "somewhat interesting", and patterns from 0.75 to 1.00 are patterned as "very interesting".
[0084]
Thereby, on the screen shown in FIG. 12, the documentary (1-1) whose importance value is 0.61 (0.50 ≦ 0.61 ≦ 0.74) is displayed as “somewhat interesting”. Have been. In addition, the sport (1-2) whose importance value is 0.11 (0.00 ≦ 0.11 ≦ 0.24) is displayed as “almost no interest”, and its importance value is 0. The overseas North America (2-3) where .88 (0.75 ≦ 0.88 ≦ 1.00) is displayed as “very interested”. By displaying in this manner, the configuration of the user's own interest data can be presented to the user in an easily understandable manner.
[0085]
In step S63, interest data presentation section 107 accepts the designation of the attribute. At this time, the user inputs desired attributes. For example, when the user A wants to display the attribute of “region”, the user A operates the remote controller and inputs “2”.
[0086]
In step S64, interest data presentation section 107 displays the specified attribute. At this time, for example, a screen as shown in FIG. 12 is displayed on the monitor of the television receiver 3-1. FIG. 12 is a radar chart in which each attribute (overseas Asia, overseas Europe, overseas North America, etc.) regarding the attribute 2 (region) of the personal interest data 122 of the user A is displayed as an axis. In this radar chart, points (161-1, 161-2, 161-3,...) On the axis representing each attribute represent the importance of the attribute and are close to the center point 163 of the radar chart. The importance is lower as the distance from the center point 163 is higher.
[0087]
In this example, each attribute of the personal interest data 122 is displayed in a radar chart, but the display format may be changed based on a user's specification. For example, instead of the screen shown in FIG. 12, each attribute of personal interest data 122 of user A may be displayed as a bar graph. FIG. 14 shows a display example at this time. In FIG. 14, the value of the importance of each attribute (documentary, sports, and information) regarding the attribute 1 of the personal interest data 122 of the user A is displayed in a bar graph.
[0088]
At this time, a plurality of attributes may be combined and displayed as a new attribute. For example, the value of importance of “variety” in the attribute “genre” in the personal interest data 122 of the user A is 0.80, and the value of importance of “late night” in the attribute “time zone” is 0. In the case of .40, for example, a new attribute "midnight variety degree" may be displayed with its importance value set to 0.60 ((0.80 + 0.40) / 2). In addition, a combination of “sports” and “travel gourmet” in the attribute “genre” may be displayed like a new attribute “outdoor degree”. By doing so, the interest data can be presented to the user in a more understandable manner.
[0089]
Alternatively, a plurality of attributes may be combined and displayed as a new attribute based on the correlation between the attributes. For example, the server 6 analyzes a plurality of interest data, and interest data having a high importance of the attribute “sports relay” which forms the interest data also has a high importance of the attribute “sports news”, that is, the attribute “sports relay”. When the correlation of “sports news” is analyzed to be high, the attribute “sports relay” and the attribute “sports news” may be combined and displayed as a new attribute “sports”.
[0090]
Further, the correlation between attributes may be analyzed for interest data of a specific individual, and an attribute specific to the individual may be generated. For example, if it is analyzed that the attribute “travel” and the attribute “Asia” have high correlation in the personal interest data of the user B, the attribute “Asia / Travel” is displayed when the interest data of the user B is displayed. It may be.
[0091]
When a plurality of attributes are combined and displayed as one attribute, the combined attributes can be displayed as needed. FIG. 15 shows a display example in this case. For example, in FIG. 15A, when the attribute “sports relay” and the attribute “sports news” forming the interest data are combined and displayed as one attribute “sports” and its importance value (0.73), Based on the user's instruction, a screen as shown in FIG. 15B is displayed. The user's instruction is performed, for example, by operating the input unit 76 and double-clicking the area 201 on the display screen. In FIG. 15B, the attribute “sports relay” and the attribute “sports news” are displayed together with their importance values (0.75 and 0.71).
[0092]
FIG. 16 is a diagram illustrating another display example when a plurality of attributes are combined and displayed as one attribute. FIG. 16A is a diagram showing an example in which the attributes of interest data of a certain user (for example, user B) and the importance thereof are displayed in a radar chart, similarly to FIG. In this example, “Italy”, “France”, “United Kingdom”, “Germany”,... Exist among the attributes constituting the interest data of the user B, and these attributes are combined to form a new attribute. It is labeled "Overseas Europe".
[0093]
For example, when the user operates the input unit 76 and double-clicks the point 221 on the axis “Overseas Europe” in the radar chart of FIG. 16A, a screen as shown in FIG. 16B is displayed. FIG. 16B shows a plurality of attributes “Italy”, “France”, “UK”, “Germany” combined as the attribute “Overseas Europe” in FIG. It is displayed as a chart.
[0094]
In this way, the interest data is displayed.
[0095]
Returning to FIG. 7, in step S45, the interest evaluation input unit 108 receives an input for changing interest data. At this time, the change input is performed as follows. The user A operates the input unit 76 to correct the attribute value to be changed. For example, if the user A looks at the radar chart shown in FIG. 12 and finds himself more interested in Asia, he drags a point 161 on the overseas Asian axis of the radar chart in the direction of arrow 162, Drop it at the desired position on the overseas Asian axis. By doing so, interest in Asia is set high in the transferred interest data.
[0096]
When the user A looks at the bar graph shown in FIG. 14 and feels that he is more interested in sports, he drags the point 181 of the bar graph in the direction of the arrow 182 and drops it to a desired position. By doing so, interest related to sports is set high in the transferred interest data.
[0097]
Of course, if the user determines that there is no need to change the interest data, this change is not made.
[0098]
Then, in step S46, the interest evaluation input unit 108 causes the interest extraction unit 102 to update the interest data. Thereby, for example, the personal interest data 122 of the user A is stored with the importance of “overseas Asia” set to be high.
[0099]
When the changed attribute is an attribute obtained by combining a plurality of attributes, the value of the importance of each of the combined attributes is changed. For example, in the radar chart shown in FIG. 16A, when the point 221 on the overseas European axis is dragged and dropped in the direction of the arrow 222, the attributes "Italy", "France", " The importance of “United Kingdom”, “Germany”,.
[0100]
Thus, the interest data is changed. The interest data is displayed in a format that is easy for the user to understand, and the user can change the value of the importance of the attribute included in the interest data to a desired value. Can be. Also, since a plurality of attributes are combined and displayed as one new attribute, the value of the importance of the plurality of attributes can be changed by one operation, and the interest data can be changed more easily. Can be.
[0101]
In the above, an example in which the interest data is displayed on the monitor of the television receiver 3-1 and the user operates the input unit 76 to change the interest data has been described. The data may be displayed on the intelligent remote controller attached to the device 3-1 and the interest data may be changed by the user operating the remote controller.
[0102]
In this case, the user is authenticated by the intelligent remote controller, and the interest data of the authenticated user is displayed on the display unit of the intelligent remote controller. By doing so, the user can change the interest data without others seeing his / her interest data, and the privacy of the user is further protected.
[0103]
