The information terminal 100 also comprises: evaluation value setting means which sets an evaluation value to the content on the basis of the preference degree and the application use degree; and content processing means which processes the content on the basis of the set evaluation value.

Description

  The present invention relates to an information terminal, a portable terminal, a content processing method, and a program.

  In a content distribution service for mobile terminals and a content storage service for multimedia broadcasting for mobile terminals, the content is distributed and the content is automatically stored in the user's mobile terminal.

  However, since the capacity of the storage device is limited, if the distributed content is left unattended, new content cannot be stored. In order to secure a storage area so that new content can be received, it is necessary to delete the stored content.

  In order to determine the content to be deleted, it is necessary to determine whether the user is interested or not by checking the content. For this reason, when the number of contents increases, it takes time and effort. Therefore, it is conceivable to organize the content by using a system that evaluates the content using user preferences so that it is not necessary to check the content contents.

  As a system for recommending content based on user preferences, for example, there is a content presentation system that evaluates content using a user's content viewing history and presents highly evaluated content (for example, Patent Document 1). This system compares the user's past viewing content name with the content name of the content scheduled to be broadcast in the future, and preferentially displays the common content as content that meets the user's preference.

  There has also been proposed an apparatus that manages user preferences according to user situations such as usage time periods and recommends content based on the user preferences according to the circumstances (for example, Patent Document 2).

JP 2001-275056 A JP 2005-165454 A

  Since the system disclosed in Patent Document 1 evaluates content based on the content name, the accuracy of the evaluation is low, and it can cope with long-term changes in user interest. There is a problem that it is not possible to respond to short-term changes in demand, such as content that you want to watch differently.

  In addition, the apparatus disclosed in Patent Document 2 sets content evaluation values for each situation such as for each time period. Since this apparatus cannot predict in which situation the user will view the content, it cannot specify the content to be deleted. Therefore, this apparatus cannot be used for specifying the content to be deleted.

  A similar problem exists when receiving distribution of content in accordance with preferences. In other words, the system disclosed in Patent Document 1 has a high probability that it does not follow the preference even if it is distributed based on the evaluation value. In addition, it is possible to receive distribution of content according to the current situation of the user, but since the user cannot predict in which situation the content will be viewed, the content expected to be viewed by the user is distributed in advance. Not suitable to leave. As described above, even if a system for evaluating the content is used, it is not easy to appropriately select, delete or download the content according to the user's behavior pattern.

  The present invention has been made in view of the above circumstances, and an information terminal, a portable terminal, a content processing method, and a program that appropriately evaluate content according to user's preference and situation and process the content according to the evaluation value are provided.

  “Date and time” is the date and time that the RTC 40 measured when the user started viewing the content.

  “Position” and “Movement speed” indicate the position (latitude and longitude) and the movement speed measured by the position information acquisition unit 30 at the time when viewing (playback) of the content is started.

  “Estimated location” indicates the location of the user at the time of starting viewing the content. The estimated location is determined by the control unit 10 based on basic information 55 described later.

  “Genre” indicates the genre of the viewed content. The genre is determined by the control unit 10 based on the basic information 55.

  The “keyword” is a keyword assigned to the content viewed by the user. The keyword is determined by the control unit 10 based on the basic information 55.

  The “application” is a program used for viewing content corresponding to the user.

  The basic information 55 stored in the storage device 50 shown in FIG. 2 is basic information for executing processing to be described later.

  The basic information 55 is extracted basic information 55a shown in FIG. 5 (A), time zone definition information 55b shown in FIG. 5 (B), a place estimation table 55c shown in FIG. 5 (C), and registration shown in FIG. 5 (D). Application information 55d is included.

  As shown in FIG. 5A, the extraction basic information 55a defines what words and phrases are extracted as “genre” and “keyword” from the “metadata” stored in the content 52. Stores information (words).

  The time zone definition information 55b defines a time zone for one day, as shown in FIG.

  In the place estimation table 55c, as shown in FIG. 5C, the estimated place and conditions for estimating the place are defined in advance by the manufacturer and the user.

  As shown in FIG. 5D, the registered application information 55d stores information that identifies applications that can be used to view content.

  As shown in FIG. 6, the situation table 56 registers a situation expected to be encountered by the user and its identification information. The “situation” is composed of a “time zone” and an “estimated place” indicating the location of the user. The situation table 56 is configured by adding and storing identification information to the situation when the user actually views the content.

  The preference level table 57 stored in the storage device 50 shown in FIG. 2 is a “situation” defined by the situation table 56 as shown in FIG. Is stored as information indicating how much the content having “” is viewed. This information includes data indicating “situation”, “genre”, “keyword”, and “user preference”.

  The “user preference” stores data indicating how much content the user has viewed in the corresponding “situation” and having metadata including the words “genre” and “keyword”. Yes.

  The application execution level table 58 stored in the storage device 50 shown in FIG. 2 is a “situation” defined by the situation table 56 as shown in FIG. Information indicating how much “application” has been used is stored. This information includes data indicating “situation”, “application”, and “application execution degree”.

  The data item of “application execution degree” stores data indicating how much the user has executed the corresponding “application” in the corresponding “situation”.

  Next, the operation of the information terminal 100 having the above configuration will be described. First, a process in which the information terminal 100 updates the viewing history information 54 and the situation table 56 when the user views content will be described with reference to the flowchart of FIG.

  First, when the application program registered in the registered application information 55d shown in FIG. 5D is activated and content is displayed, the control unit 10 displays the viewing history information 54 shown in FIG. 4 and the content shown in FIG. Processing for updating the situation table 56 is started.

  When this process is started, the control unit 10 first acquires the current time measured by the RTC 40, adds a new record to the end of the viewing history information 54, and registers the acquired date and time (step S1).

  Next, the control unit 10 acquires the current position (latitude, longitude) and the moving speed measured by the position information acquisition unit 30, and registers them in the additional records (step S2).

  Next, the control unit 10 applies the acquired position and moving speed to the location estimation table 55c shown in FIG. 5C, estimates (specifies) the user's whereabouts, and determines the estimated location (estimated location). Register in the additional record (step S3).

  Next, the control unit 10 performs morphological analysis on the metadata attached to the content viewed by the user and divides it into words. Next, the words belonging to “genre” and the words belonging to “keyword” in the extraction basic information 55a shown in FIG. 5A are registered in the additional record as “genre” and “keyword” (step S4).

  Next, the control unit 10 acquires the identification information of the application used for viewing the content and registers it in the additional record (step S5).

  In this way, the control unit 10 updates the viewing history information 54 every time the user views the content.

  Next, the control unit 10 proceeds to a process of updating the situation table 56. First, the control unit 10 applies the date and time specified in step S1 to the time zone definition information 55b to specify the time zone to which it belongs (step S11).

  Next, the control unit 10 determines whether or not the set of the “time zone” estimated in step S11 and the “estimated place” estimated in step S3 is already registered in the situation table 56 (step S12).

  If it is not registered (step S12; NO), identification information is added, and the situation (a set of time zone and estimated place) is registered in the situation table 56 (step S13), and the process is terminated. On the other hand, if registered (step S12; YES), step S13 is skipped and the process is terminated.

  In this way, the control unit 10 updates the viewing history information 54 and the situation table 56 every time content is viewed.

  In this way, the control unit 10 allows the user's situation A, B. . . And the contents of the content specified by the genre and keyword, and the application, browser, operation player used to view the content. . . And specify.

  Next, the operation of updating the preference level table 57 and the application execution level table 58 will be described with reference to the flowchart shown in FIG.

  First, the control unit 10 starts the processing shown in FIG. 10 at a preset time, for example, at midnight, and first, the content registered in the viewing history information 54 stored in the storage device 50 is started. One unprocessed one is selected (step S21). The contents may be selected in order of name, in order of viewing date and time, or arbitrarily.

  When the content is selected, the control unit 10 determines whether a combination of data matching the combination of the “situation” in which the user viewed the content, the “genre” of the content, and the “keyword” exists on the preference table 57. Determination is made (step S22).

  If it determines with existing (step S22: YES), the control part 10 will add a predetermined value, for example, 0.1, for example to the "user preference" corresponding to the combination (step S23).

  On the other hand, if it is determined that it does not exist (step S22: NO), the control unit 10 registers the specified combination of data in the preference table 57 (step S24), and sets the “user preference” corresponding to the registered data. A predetermined initial value, for example, 0.1 is set (step S25).

  Next, the control unit 10 determines whether a combination that matches the combination of the “situation” in which the user has viewed the selected content and the “application” used is present in the application execution degree table 58 (step S31).

  If it is determined that it exists (step S31: YES), the control unit 10 adds a predetermined value, for example, 0.1 to the “application execution degree” corresponding to the identified combination of data (step S32).

  Next, it is determined whether or not unprocessed content exists in the viewing history information 54 (step S35).

  On the other hand, if it is determined that the combination does not exist in the application execution level table 58 (step S31: NO), the control unit 10 registers the specified combination of data in the application execution table 58 (step S33).

  Next, the control unit 10 sets an “application execution degree” corresponding to the combination of the identification information of the registered situation and the application to a predetermined initial value, for example, 0.1 (step S34).

  After step S32 or S34, the control unit 10 determines whether unprocessed content exists in the viewing history information 54 (step S35).

  If it determines with existing (step S35: YES), the control part 10 will return a process to step S21. On the other hand, if it determines with not existing (step S35: NO), the control part 10 will complete | finish a process.

  In this way, the control unit 10 periodically updates the preference level table 57 and the application execution level table 58.

  In other words, the control unit 10 determines whether the situation A, B. . . Separately, the content of the viewed content (genre / keyword) and the user preference level that is the level of viewing are obtained, and the application used for viewing the content and the application execution level corresponding to the usage level are calculated according to the situation. It functions as a means to obtain.

  Next, processing of the information terminal 100 related to content evaluation / deletion will be described with reference to the flowcharts shown in FIGS.

  The control unit 10 starts the processing illustrated in FIG. 11 after executing a predetermined time, for example, “preference level table / application execution level table update processing” illustrated in FIG. 10.

  First, the control unit selects one unprocessed content from the contents 52 stored in the storage device 50 (step S100). Note that the control unit 10 may select contents in order of names, may select in order of reception date, or is arbitrary.

  The control unit 10 performs morphological analysis on the metadata corresponding to the selected content, and extracts a noun phrase from the metadata subjected to the morphological analysis. The control unit 10 extracts “genre” and “keyword” from the extracted noun phrase according to the extraction basic information 55a (step S110).

  Next, the control unit 10 sets the evaluation value of the content selected in step S100 (step S120).

  Details of the evaluation value setting process will be described with reference to the flowchart shown in FIG.

  The control unit 10 determines whether a combination that matches the combination of “genre” and “keyword” extracted in step S110 exists in the preference table 57 (step S121).

  When it is determined that a matching combination exists in the preference level table 57 (step S121; YES), the corresponding user preference level is acquired (step S122). When it is determined that there are a plurality of corresponding combinations, the maximum user preference level is acquired.

  Subsequently, the control unit 10 determines a “situation” corresponding to the acquired “user preference degree”, and identifies a matching situation among the situations registered in the application execution degree table 58 (step S123).

  Next, an “application” corresponding to the identified “situation” is identified on the application execution level table 58 (step S124).

  It is determined whether or not the identified “application” includes an “application” for reproducing the content selected in step S100 (step S125).

  If there is a matching “application” (step S125; YES), the application execution level corresponding to the matching “application” is acquired (step S126).

  Subsequently, an evaluation value is calculated from the “user preference level” acquired in step S122 and the “application execution level” acquired in step S126, and is registered in the storage device 50 in association with the content (step S127).

  The evaluation value is set by, for example, the product, sum, weighted average, and the like of “user preference level” and “application execution level”.

  On the other hand, when it is determined in step S121 that the extracted combination of “genre” and “keyword” is not registered in the preference table 57 (step S121; NO), and in step S125, the application execution table 58 When it is determined that there is no application for reproducing the selected content among the specified applications (step S125; NO), the evaluation value of the selected content is set to 0 (step S128).

  Returning to FIG. 11, the control unit 10 determines whether there is content for which no evaluation value is set (step S130).

  If it determines with existing (step S130: YES), the control part 10 will return a process to step S100.

  On the other hand, if it is determined that there is no content for which no evaluation value is set (step S130: NO), the control unit 10 sorts the content in order of evaluation value, and content for which an evaluation value equal to or less than a predetermined threshold is set. Is deleted from the storage device 50, and the process is terminated (step S140). Note that the threshold value may be set by default at the time of factory shipment or may be set by the user.

  As described above, the control unit 10 identifies the content to be evaluated, its contents (genre, keyword), and the application necessary for viewing, and based on the contents of the identified content and the preference table, the contents The first degree (preference level) at which the content is being viewed and the situation at that time are obtained, and in the obtained situation, the content is viewed using an application used for reproducing the content. The degree of 2 is obtained based on the application execution degree table. Then, an evaluation value is set for the content based on the obtained first degree and the second degree, and content deletion processing is performed based on the evaluation value.

  Next, the above operation will be described based on a specific example. First, the content 52 shown in FIG. 3 is stored in the storage device 50, and “Good morning news” in the first row is played at home at 7:30 am on July 22, 2011 while sitting on a chair. To do.

  In this case, a record is added to the end of the viewing history information 54 shown in FIG. 4 and the date and time “2011/07 / 22.07: 30” are registered by the process when viewing the content shown in FIG. 9 (step S1). Subsequently, the position (latitude, longitude) and moving speed (in this case, 0 km / h because sitting) are acquired from the position information acquisition unit 30 and registered in the additional record (step S2).

  Subsequently, the position and the moving speed are applied to the place estimation table shown in FIG. 5C, and “home” is estimated as the place and registered in the additional record (step S3).

  Next, “news” as a genre and “economy” as a keyword are extracted from the metadata and the extraction basic information 55a shown in FIG. 5A and registered in an additional record (step S4).

  Next, “electronic book viewer” is identified as an application used to reproduce the content, and is registered in the additional record (step S5).

  Subsequently, with reference to the time zone definition information 55b shown in FIG. 5B, it is determined that the viewing time belongs to the time zone of 07: 0 to 08:00 (step S11).

  Subsequently, it is determined whether or not there is a combination of the time zone “07: 0-8: 00” and the estimated place “home” in the situation table 56 shown in FIG. 6 (step S12). Therefore, step S13 is skipped and the process is terminated.

  Next, at a predetermined time, information on this reproduction is selected from the viewing history information by the preference table / application execution table update processing shown in FIG. 10 (step S21), and “situation” = A, “genre” It is determined whether or not a combination that matches “= news” and “keyword” = economy exists in the preference table (step S22). In this example, since a combination that matches this combination exists in the first row of the preference table 57 (step S22; YES), a predetermined value, for example, 0.1 is added to the corresponding preference = 0.9. Then, it is updated to 1.0 (step S23).

  Next, it is determined whether or not a combination that matches the corresponding “situation” = A and “application” = book viewer exists in the application execution degree table 58 (step S31). In the example of FIG. 8, since there is a combination of “situation” = A and “application” = book viewer corresponding to the first row of the application execution table 58 (step S31; YES), the corresponding application execution degree = 0. A predetermined value, for example, 0.1 is added to 5 and updated to 0.6 (step S32).

  Next, it is assumed that “baseball relay” in the second row of the content 52 shown in FIG. 3 is selected in step S100 as the target of the content evaluation / deletion processing shown in FIGS.

  In this case, “genre” = “relay” and “keyword” = baseball are extracted from the metadata of the selected content and the extraction basic information 55a shown in FIG. 5A (step S110).

  Next, it is determined whether or not a combination corresponding to this combination exists in the preference table 57 shown in FIG. 7 (step S122). In this example, since it exists, the corresponding user preference level 0.8 is acquired (in this example, this is the maximum value).

  Subsequently, the corresponding “situation” = B is specified, and it is determined whether or not this is registered in the application execution degree table 58 (step S123). In this example, since “situation” = B is registered, the corresponding application (moving image player,...) Is specified (step S124).

  Subsequently, it is determined whether or not there is an application = action player for reproducing the selected content among the identified applications (moving image player,...) (Step S125). In this example, since the moving image players match as applications (step S125; YES), an application execution level = 0.9 corresponding to the matching application is acquired from the application execution level table 58 (step S126).

  Next, an evaluation value, for example, K · 0.8 · 0.9, K1 * 0.8 + k2 * 0.9, is obtained from the user preference level 0.8 acquired in step S122 and the acquired application execution level 0.8. Is obtained (step S127). K, K1, and K2 are coefficients.

  The evaluation value obtained as described above is compared with a threshold value. If the evaluation value is smaller than the threshold value, it is deleted in step S140, and if it is larger, it is left.

  As described above, the information terminal 100 according to the present embodiment specifies the content content by the genre and the keyword, determines what content the user is interested in based on the user preference, and The application execution degree is used to evaluate what kind of application is used in a situation where the user is viewing that kind of content, and the evaluation value is set based on the user preference degree and the application execution degree.

  Therefore, for example, content that the user does not show interest is rated low, and content that is played back by an application that cannot be used in a situation where the user browses such content is rated low. Therefore, it is possible to more accurately identify and delete content that is unlikely to be reproduced.

  Also, the information terminal 100 evaluates the content of the content 52 and deletes the content with a low evaluation value, regardless of the user's special operation, and organizes the content of the content 52. For this reason, the information terminal 100 according to the present embodiment can secure a storage area for storing new content received by the communication unit 20 from the outside.

(Embodiment 2)
In the above description, an example has been described in which content stored in the storage device 50 in the information terminal 100 is evaluated and deleted. However, the content to be evaluated specifies metadata necessary for evaluation and a corresponding application. If information can be acquired, it may be stored in an external device.

  In this case, the information terminal 100 receives an EPG (Electronic Program Guide) 60 as shown in FIG. 13 from an external device such as a server before evaluating the content. The EPG 60 stores information indicating what kind of metadata the content stored in the external device has and what application it corresponds to.

  The information terminal 100 obtains an evaluation value of each content based on the EPG 60, and instructs an external device to delete the content having a low evaluation value.

(Embodiment 3)
In the first and second embodiments, the example used when deleting the evaluation value is shown. However, for example, the present invention is also applicable to the case where content stored in an external device is evaluated and a content with a high evaluation value is received. Can be applied. Also in this case, the communication unit 20 receives an EPG (Electronic Program Guide) 60 as shown in FIG. 13 from an external device such as a server before receiving the content.

  Next, content evaluation / reception processing of the information terminal 100 will be described with reference to the flowchart shown in FIG.

  The control unit 10 of the information terminal 100 starts the content evaluation / reception process shown in FIG. 14 at the timing of content selection reception. First, one content is specified and its evaluation value is set (step S200). The method for setting the evaluation value is the same as in the first and second embodiments.

  Next, the control unit 10 determines whether there is content for which no evaluation value is set (step S201).

  If it determines with existing (step S201: YES), the control part 10 will return a process to step S200.

  On the other hand, if it is determined that there is no content for which the evaluation value is not set (step S201: NO), the control unit 10 specifies a certain number of content in descending order of the evaluation value and instructs the external device to transmit. Then, the contents transmitted from the external device are sequentially received (step S202). The number of contents to be received can be arbitrarily set according to the free capacity of the storage device 50.

  In this way, the information terminal 100 is not limited to deletion, and also when receiving content, appropriately evaluates the content and reproduces it according to the user's behavior pattern with high user preference. It is possible to identify and receive content that is likely to be received.

  In the above embodiment, the genre to which the content belongs and the keyword assigned to the content are used to specify the content, but the type of information is arbitrary as long as the content can be specified to some extent. . For example, it is possible to use category, tag, link destination, quotation destination, attribute information of content provided by a third party as a service, and the like.

  In addition, although “time zone” and “location” are specified as information for specifying the user's situation, other information may be used. For example, the user's physical activity status (sleeping, walking, running, resting, etc.) is specified from a speedometer, heart rate, etc., and these are used as data indicating the state. It is also possible. Also, social activities such as working or studying may be discriminated (the user may designate them), and the situation may be set for each social activity. Furthermore, the situation may be a combination of the time zone, whereabouts, physical activity status, social activity status, and the like.

  Further, in the preference level table 57, the user preference level is used as the degree to which a content of a certain content is viewed in a certain situation. This degree of preference increases as the number of times of viewing increases. This may be normalized by the total number of viewing times, and the degree of preference = viewing degree may be obtained. Moreover, the reference | standard which calculates | requires a user preference may be limited to the latest viewing N times, viewing within m months, etc., and a user's preference change may be reflected in a user preference promptly.

  In this case, based on the viewing history registered in the viewing history information 54, the preference degree table is configured only for viewing within the latest N times or within the most recent m months. The same applies to the application execution degree table 58.

  The information terminal 100 is arbitrary such as a terminal having a character input function, such as a mobile phone, a smartphone, a game machine, a tablet PC (Personal Computer), a notebook PC, a PDA (Personal Data Assistants).

  The configuration and operation described above are examples, and the configuration and operation can be appropriately changed as long as the same function can be achieved.

  Further, the function of the information terminal 100 may be realized by a computer executing a program. A program for realizing the functions of the information terminal 100 is stored in a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disc Read Only Memory), a DVD (Digital Versatile Disc), or an MO (Magneto Optical Disc). It may be downloaded to a computer via a network.
