Description

  The present invention relates to a content management apparatus, method, and program, and more particularly, to a content management apparatus, method, and program for assigning tags to content for management.

  2. Description of the Related Art In recent years, a content management apparatus that manages by assigning a search tag to digital content (hereinafter simply referred to as “content”) in which video, images, music, text, or the like, or a combination thereof, is converted into digital data. Is popular. When a user registers content in the content management apparatus, the user assigns a tag for classifying the content. For example, when the content is content related to travel, the user gives “travel” as a tag to the content. In this way, when a user searches for content later using “travel” as a keyword, this content can be found.

  A mechanism has been proposed in which when a user registers content in a content management apparatus, a tag candidate to be added to the content is displayed, and a tag to be assigned to the content is selected from the candidates (for example, see Patent Document 1).

JP 2012-42998 A

  However, in Patent Document 1, when a user assigns a tag to a content management apparatus and registers the content, the tag to be given to the content can be selected from the candidates. However, tag candidates include tags having various meanings. . For example, if the tag attached to the content is “travel” and the user searches for the content using “travel” as a keyword, the search results will include “travel to New York” and “travel to London” as well as unnecessary “ “Travel equipment” may also be included. Also, if the tag is “Cooking”, when a user searches for content using “Cooking” as a keyword in order to acquire “Japanese cooking” content, “Western cooking” and “Chinese cooking” will be searched. As a result, the user's intended result may not be obtained.

  Based on the above, when a user registers a content by adding a tag to the content management device, it is desirable to add a plurality of tags having no meaning to the content. If a unique tag can be assigned to the content, the result intended by the user can be obtained even if the user searches the content using the tag as a keyword.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a content management apparatus and method, and a program that can easily obtain a search result intended by a user when searching for content using a tag. To do.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of a content management apparatus according to an embodiment of the present invention.

  In FIG. 1, a content management apparatus 100 manages a digital content such as video, image, music, text, etc. (hereinafter referred to as “content”) by assigning a search tag, for example, a personal computer (PC) or the like. Information processing apparatus. Note that the content management apparatus may be realized by a single PC or a plurality of computers in which various functions are distributed. When realized by a plurality of computers, it is preferable to connect the plurality of computers to each other via a communication line such as a LAN (Local Area Network). Further, the content management apparatus may be realized by a server on the network.

  The content management apparatus 100 includes a CPU 101, ROM 102, RAM 103, HDD 104, operation input IF 105, display IF 106, network IF 107, and system bus 112.

  The CPU 101 is a central processing unit (CPU) that controls the entire content management apparatus 100. The ROM 102 is a Read Only Memory (ROM) that stores programs and various setting information. The RAM 103 is a RAM (Random Access Memory) that temporarily stores programs and data supplied from the HDD 104 or the external Internet 114.

  The HDD 104 is a hard disc drive (HDD). The HDD 104 may be a memory card, an optical disk, a magnetic disk, an IC card, or the like that can be detached from the content management apparatus 100.

  The operation input IF 105 is an interface that receives user operations and is connected to a pointing device 109 and a keyboard 110 for inputting various data and controls transmission / reception of operation input data to / from the CPU 101 connected via the system bus 112. .

  The display IF 106 is connected to a display 111 that displays content managed by the content management apparatus 100, apparatus status, and the like, and is an interface that controls transmission / reception of display data to / from the CPU 101 and the HDD 104 connected via the system bus 112. is there.

  A network IF 107 is a network interface that is connected to an external network such as the Internet 114 and controls transmission and reception of data.

  The system bus 112 is a system bus that connects the above-described units of the CPU 101 to the network IF 107 so that they can communicate with each other.

  Next, a content registration method in the content management apparatus 100 will be described.

  The content management apparatus 100 displays a content registration screen 201 for accepting content registration as shown in FIG.

  In the content registration screen 201, a content input field 202 for inputting the location of the content, and a registration button 203 for acquiring the content from the location input in the content input field 202 and registering the content in the content management apparatus 100. Is arranged.

  FIG. 5 is a flowchart of content registration processing using the content registration screen 201 shown in FIG. This process is realized by the CPU 101 reading out and starting a program supplied from the HDD 104 or the Internet 114 and controlling each unit according to these programs.

  In FIG. 5, the CPU 101 determines whether a content registration request due to pressing of the content registration button 203 on the content registration screen 201 has been detected (step S <b> 501). If the result of this determination is that a content registration request has not been detected (NO in step S501), the determination in step S501 is repeated. On the other hand, when a content registration request is detected (YES in step S501), the CPU 101 acquires the content entity from the location of the content input in the content input field 202 (step S502).

  Next, the CPU 101 generates and assigns a content identifier to the content acquired in step S502. Then, the assigned content identifier, the content name, the destination path where the content is stored, and the meta information are registered in the content table 401 and stored in the HDD 104 (step S503), and this process ends.

  Here, various table information stored in the HDD 104 of the content management apparatus 100 and used for managing the content by attaching a tag will be described.

  In FIG. 4A, a content table 401 is a table for managing content. The content identifier 402 is an identifier for uniquely identifying content. A name 403 is a name of the content. A path 404 is a path indicating the location of the content. The meta information 405 is meta information corresponding to the content.

  In FIG. 4B, a tag table 411 is a table for storing tag information managed by the content management apparatus 100. The tag identifier 412 is an identifier for uniquely identifying a tag. A character string 413 is a character string of the tag.

  In FIG. 4C, a content tag association table 421 is a table for managing which content is associated with which tag.

  The content identifier 422 is a value of the content identifier 402 in the content table 401. The tag identifier 423 is a value of the tag identifier 412 in the tag table 411.

  The content tag related table 421 may be used as follows. For example, it is assumed that a record whose content identifier 402 is “content identifier 1” is acquired from the content table 401. When the content tag corresponding to this record is searched by associating the value of the content identifier 422 of the content tag relation table 421 with “content identifier 1”, the value of the tag identifier 423 becomes “tag identifier 1”. It can be identified as a tag. Of course, when acquiring the character string of “tag identifier 1” and related information, the record is specified by associating the value of the tag identifier 412 of the tag table 411 with “tag identifier 1”, and the character string of the record These values can be obtained by referring to the related information.

  Alternatively, the record 414 of the tag table 411 is identified from the character string of the tag, the value of the tag identifier 412 of the record 414 is acquired, and the record 424 of the content tag related table 421 and the record 406 of the content table 401 may be traced. . Thereby, a list of contents to which a tag is attached can be acquired.

  In FIG. 4D, a dictionary table 431 is a table for managing information relating to the meaning of the tag character string. The character string 432 is a character string of the tag, and the meaning 433 is the meaning of the character string.

  The dictionary table 431 may be used as follows. For example, referring to the character string of the tag input in the tag input field 212 of FIG. 2B and the meaning of the character string 413 of the tag table 411, the character string 432 of the dictionary table 431 is collated. The value of the meaning 433 is acquired from the corresponding record.

  Next, a method for assigning a tag to content registered in the content management apparatus 100 will be described.

  In the content management apparatus 100, a tag setting screen 211 for giving a tag to the content as shown in FIG.

  In the tag setting screen 211, a tag input field 212 for inputting a tag character string and a registration button 203 for registering the character string input in the tag input field 212 as a content tag are arranged.

  In the tag setting screen 211, an identifier (content identifier) of a content to which a tag is attached is embedded. That is, the tag registered on the tag setting screen 211 is given to the content corresponding to the content identifier embedded in the tag setting screen 211.

  FIG. 6 is a flowchart of tag registration processing using the tag setting screen 211 shown in FIG. This process is realized by the CPU 101 reading out and starting a program supplied from the HDD 104 or the Internet 114 and controlling each unit according to these programs.

  In FIG. 6, the CPU 101 determines whether an input of a tag character string to the tag input field 212 on the tag setting screen 211 is detected (step S601). As a result of this determination, when the input of the tag character string is not detected (NO in step S601), the determination in step S601 is repeated. On the other hand, when the input of the tag character string is detected (YES in step S601), the CPU 101 acquires the tag character string from the tag input field 212 (step S602).

  Next, the CPU 101 confirms the uniqueness of the tag character string obtained in step S602 (step S603). Specifically, the CPU 101 acquires a record corresponding to the character string of the tag acquired in step S602 from the record 434 of the dictionary table 431 shown in FIG. Then, the CPU 101 refers to the value of the meaning 433 of the acquired record 434.

  Next, in step S604, the CPU 101 determines whether the character string of the tag acquired in step S602 is unique based on the value of the meaning 433 referred to in step S603. For example, if there are two values “travel” and “dishes” in the meaning 433 of the character string acquired from the dictionary table 431 by the above-described confirmation method, it is determined that there is no uniqueness, and only the value “travel” is obtained. If there is no plural meaning, it is determined that there is uniqueness.

  If it is determined in step S604 that the character string of the tag is unique, the CPU 101 displays the character string of the tag acquired in step S602 in the tag input field 212 (step S607), and ends this process. On the other hand, if it is determined in step S604 that the character string of the tag is not unique (NO in step S604), the CPU 101 generates a unique tag candidate based on the character string of the tag input in step S602. (Step S605). Specifically, the CPU 101 acquires a record corresponding to the character string of the tag acquired in step S602 from the record 434 of the dictionary table 431. Then, the CPU 101 refers to the value of the meaning 433 from the acquired record, excludes a record having a plurality of meanings, and sets a character string of the remaining record as a tag candidate. Further, the CPU 101 generates tag candidates by combining the acquired record meaning 433 (its value (character string)) with the tag character string acquired in step S602. For example, if the tag character string acquired in step S602 is “Kyoto”, “Kyoto trip”, “Kyoto cuisine”, etc. are selected as tag candidates in combination with the acquired meaning “travel”, “cooking”, and the like. . It is not always necessary to use the character string acquired in step S602, and the tag is obtained by combining the meaning character string obtained from the dictionary table 431 based on the character string and the character string obtained from the content meta-information. Candidates may be generated.

  Next, the CPU 101 performs tag editing processing on the tag candidate generated in step S605 (step S606), and displays the result as a tag candidate 221 (see FIG. 2C) in the tag input field 212. (Step S607) and the process is terminated.

  The editing processing of the plurality of tags in step S606 includes rearranging the tag candidates in descending or ascending order, or replacing specific characters of the tag candidates with other characters. For example, if the character string of the tag includes a character string that is unacceptable for social conventions, the character string is replaced with a character string that is synonymous with the character string. If there are a plurality of character strings having the same meaning and different tag candidates, one of them is selected.

  In addition, in the editing processing of a plurality of tags in step S606, the tag candidates may be prioritized based on the meta information of the content to be tagged, and the tag candidates may be rearranged in order of priority. Thereby, the tag candidate along the content of the content to which the tag is attached can be preferentially displayed.

  The tag candidates 221 displayed in the drop-down list in the tag input field 212 are all unique tags and appropriate tags in meaning. When a tag character string is selected from the tag candidates 221, it is displayed in the tag input field 212 as a tag character string.

  Next, an operation for registering a tag displayed in the tag input field 212 on the tag setting screen 211 will be described with reference to FIG.

  FIG. 7 is a flowchart of tag registration processing executed after the processing of FIG. This process is realized by the CPU 101 reading out and starting a program supplied from the HDD 104 or the Internet 114 and controlling each unit according to these programs.

  In FIG. 7, the CPU 101 determines whether a tag registration request due to pressing of the setting button 213 is detected in a state where a tag character string is displayed in the tag input field 212 on the tag setting screen 211 (step S <b> 701). . If it is determined that a tag registration request has not been detected (NO in step S701), the determination in step S701 is repeated. On the other hand, if it is determined that a tag registration request has been detected (YES in step S701), the CPU 101 acquires the tag displayed in the tag input field 212 (step S702).

  Next, the CPU 101 generates and assigns a tag identifier to the tag acquired in step S702, registers it in the tag table 411 together with the tag character string, stores it in the HDD 104 (step S703), and ends this processing. To do. It goes without saying that the tag registered in step S703 is used at the time of content search described later.

  Next, a method for searching for content registered in the content management apparatus 100 using tags will be described.

  The content management apparatus 100 displays a content search screen 301 as shown in FIG.

  On the content search screen 301, a tag input field 302 for inputting a tag attached to the content, and a search button for acquiring the content related to the tag input in the tag input field 302 and displaying the result 303 is arranged.

  When the CPU 101 of the content management apparatus 100 detects a content search instruction when the search button 303 is pressed, the CPU 101 searches for the content based on the tag character string input in the tag input field 302, as shown in FIG. Such a search result screen 311 is displayed. On the search result screen 311, the search result of the content is displayed in the search result display area 312.

  Next, as an example of the tag candidate editing process in step S606 in FIG. 6, an operation for editing a tag candidate based on content meta information will be described with reference to FIG.

  FIG. 8 is a flowchart showing an example of tag candidate editing processing in step S606 of FIG.

  In FIG. 8, the CPU 101 refers to the content table 401 and acquires the value of the meta information 405 from the record 406 of the content to be tagged (step S801).

  Next, the CPU 101 excludes unnecessary tags from the tag candidates acquired in step S605 of FIG. 6 based on the content meta information acquired in step S801 (step S802). For example, if the meta information acquired in step S801 is information about a landscape, the CPU 101 excludes a tag having a meaning that is less relevant to the landscape from the tag candidates. In step S803, the CPU 101 sets the result of step S802 as a tag candidate and ends the process.

  Next, as an example of the tag candidate editing process in step S606 of FIG. 6, an operation of editing a tag candidate based on the content analysis result will be described with reference to FIG.

  FIG. 9 is a flowchart showing another example of tag candidate editing processing in step S606 of FIG.

  In FIG. 9, the CPU 101 analyzes the content to be tagged and identifies the content (step S901). For example, if the subject included in the content is a person, the target content is assumed to be human-photographed content.

  Next, the CPU 101 collates the content specified in step S901 with the meaning of the tag candidate (step S902), and excludes the mismatched tag from the tag candidate acquired in step S605 of FIG. 6 (step S903). . For example, when the target content type is person photographing, tags having meanings other than person photographing are excluded from tag candidates.

  Next, in step S904, the CPU 101 sets the result of step S903 as a tag candidate and ends this processing.

  Next, as an example of the tag candidate editing process in step S606 in FIG. 6, an operation for editing a tag candidate based on information regarding the shooting location of the content will be described with reference to FIG.

  FIG. 10 is a flowchart showing still another example of the tag candidate editing process in step S606 of FIG.

  In FIG. 10, the CPU 101 acquires shooting location information regarding the content to be tagged (step S1001). Here, the information on the shooting location of the content (for example, an image or the like) uses a mechanism for detecting the position on the map such as GPS.

  Next, the CPU 101 excludes unnecessary tags from the tag candidates acquired in step S605 of FIG. 6 based on the shooting location information acquired in step S1001 (step S1002). For example, even when the tag candidate includes the character string “New York”, if the actual shooting location is Tokyo, the tag related to New York is excluded and the tag related to Tokyo is left. In step S1003, the CPU 101 sets the result of step S1002 as a tag candidate and ends the process.

  Note that what is executed as the editing process in step S606 in FIG. 6 is not limited to the above-described method or one of the methods in FIGS. 8 to 10, and various methods may be combined. Needless to say.

  According to the embodiment, when a content is registered by assigning a tag to the content management apparatus, it is determined whether the character string of the input tag has a plurality of meanings. If it is determined that the tag character string has a plurality of meanings, tag candidates having a plurality of meanings are generated based on the tag character strings. Then, the generated tag candidates are rearranged and displayed by a predetermined method. For example, when the user inputs “travel” as the tag character string and the geographical information of the content to be tagged is New York, “New York travel” is displayed as a tag candidate. This allows the user to easily search for content with the tag “New York travel”. In this manner, the user can give a unique tag to the content, and can obtain a search result intended by the user when searching for the content.

  The character string of the tag that can be input by the user is not limited to “travel”, and an arbitrary character string such as “cooking” or “movie” can be given as a tag. In the above-described embodiment, unique tag candidates instead of a plurality of meanings are displayed from such tags so that the user can give them to the content, and the result intended by the user can be obtained.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included. A part of the above-described embodiments may be appropriately combined.

  The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
