Description

  The present invention relates to an information processing device, an information processing method, and a program, and more particularly, to an information processing device, an information processing method, and a program that can suppress variations in keywords used for file search, for example.

  Conventionally, for example, a file including a moving image, a still image, sound, text, and other data is registered in the server, and the server provides the file in response to a user request. In addition, when registering a file in the server, the user causes the server to store a keyword associated with the contents of the file as information on the file to be registered.

  When the user requests the server to provide a file, the user can search for a desired file from a large number of files registered in the server by using keywords stored in the server.

In addition, there is an information processing apparatus that extracts a word as a keyword from a file to be registered when registering the file, and creates a database to be referred to when searching the file from the word extracted from the file (for example, Patent Document 1).

  Next, FIG. 2 is a block diagram showing a functional configuration example of the file server 11 of FIG.

  In FIG. 2, the file server 11 includes a storage unit 19, a communication unit 20, an input / output device 31, a database engine 32, and a file control unit 33. The database engine 32 and the file control unit 33 correspond to the CPU 12 of FIG. 1 that executes various processes by executing an application (program).

  The storage unit 19 includes a file storage unit 41 and a table storage unit 42. The file storage unit 41 stores a file registered in the file server 11. The table storage unit 42 is a table in which titles representing titles and titles of files stored in the file storage unit 41, keywords that are information about files, and the like are associated with each other, for example, the tables shown in FIGS. Remember.

  When a file to be registered in the file server 11 is transferred via a network (not shown), the communication unit 20 receives the file and supplies it to the file control unit 33.

  The input / output device 31 includes a keyboard 51 corresponding to the input unit 17 in FIG. 1 and a display 52 corresponding to the output unit 18 in FIG.

  The keyboard 51 includes, for example, a plurality of alphanumeric keys for inputting a file title, a keyword that is information related to the file, an enter key for instructing input determination (none of which are shown). Become. When the user inputs a title, keyword, or the like, the keyboard 51 supplies the file controller 33 with the title or keyword input by the user.

  The display 52 displays, for example, a screen for inputting a title of the file, a screen for inputting a keyword that is information related to the file, and the like based on the control of the file control unit 33.

  Under the control of the file control unit 33, the database engine 32 performs processing such as search, deletion, and update on the table stored in the table storage unit 42 of the storage unit 19.

  The file control unit 33 performs processing for registering a file and processing for reading a file.

  For example, in the process of registering the file, the file control unit 33 stores the file supplied from the communication unit 20 in a predetermined directory of the file storage unit 41 and inputs a file title on the display 52. A screen or a screen for inputting a keyword that is information related to a file is displayed. Then, the file control unit 33 supplies the database engine 32 with the titles and keywords input by the user operating the keyboard 51 to update the table stored in the table storage unit 42.

  Further, in the process of reading the file, the file control unit 33 supplies the keyword input by the user operating the keyboard 51 to the database engine 32, and performs a search for the table stored in the table storage unit 42. Make it. The database engine 32 performs a search on the table stored in the table storage unit 42 and supplies the file title obtained as a result of the search to the file control unit 33.

  Then, when the title of the file obtained as a result of the search is supplied from the database engine 32, the file control unit 33 displays the title on the display 52. Thereafter, when the user selects a predetermined title, the file control unit 33 reads the file of the title selected by the user from the file storage unit 41 and causes the display 52 to display the file.

  Next, FIGS. 3 to 6 show examples of tables stored in the table storage unit 42 of FIG. The table storage unit 42 stores four tables: a main keyword ID table, a sub-keyword correspondence table, a title table, and a main keyword correspondence table.

  That is, FIG. 3 is a diagram showing a main keyword ID table stored in the table storage unit 42. In the main keyword ID table, a “main keyword” that is a keyword directly related to a file stored in the file storage unit 41 and a “main keyword ID” for identifying the main keyword are associated with each other. .

  For example, when the file stored in the file storage unit 41 is a video recording a sports game, the name of the player participating in the game is the main keyword.

  In the main keyword ID table of FIG. 3, “D00001”, “D00003”, and “D00016” are registered in the main keyword ID, and the main keyword ID “D00001” is identified by the main keyword ID “D00001”. The main keyword “OS cure” is associated. The main keyword ID “D00003” is associated with the main keyword “N Shima S male” identified by the main keyword ID “D00003”, and the main keyword ID “D00016” is associated with the main keyword ID. The main keyword “Koji Tuji” identified by “D00016” is associated.

  Next, FIG. 4 is a diagram showing a sub-keyword correspondence table stored in the table storage unit 42. In the sub-keyword correspondence table, “sub-keyword”, which is a keyword related to the main keyword, is associated with “main keyword ID” for identifying the main keyword related to the sub-keyword.

  For example, when the main keyword is a sports player, the common name or nickname of the player is used as the sub keyword. In addition, a word similar to the main keyword (a word having the same sound as the main keyword, or an old font or a new font according to the Chinese character if the main keyword is a Chinese character) is also used as the sub keyword.

  In the sub-keyword correspondence table of FIG. 4, “Mister Gains”, “N Island”, “One-handed hitting method”, and “Batting Buddha” are registered as sub-keywords. The sub-keywords “Mister Gains” and “N island” are both sub-keywords related to the main keyword “N island S male” registered in the main keyword ID table of FIG. It is associated with the main keyword ID “D00003” associated with the main keyword “N island S male”. The sub-keyword “one-handed method” is a sub-keyword related to the main keyword “Osuji” registered in the main keyword ID table, and is changed to the main keyword “Osuji” in the main keyword ID table. It is associated with the associated main keyword ID “D00001”. Also, the sub-keyword “Batt Buddha” is a keyword related to the main keyword “K-Tuji” registered in the main keyword ID table. It is associated with the associated main keyword ID “D00016”.

  Next, FIG. 5 is a diagram illustrating a title table stored in the table storage unit 42. In the title table, “title ID” for identifying the title of the file stored in the file storage unit 41, “title” of the file, and “file path” indicating the path of the file correspond to each other. It is attached.

  In the title table of FIG. 5, “T00005” is registered as the title ID, and the title “T00005” includes the title “Gianz players of the past years” identified by the title ID “T00005”, and , The file path “/video/OldTimers_Gaiants.mpg” indicating the file path (including the file name) of the title “Giant's famous players of the past year” is associated.

  Next, FIG. 6 is a diagram showing a main keyword correspondence table stored in the table storage unit 42. In the main keyword correspondence table, a “title ID” for identifying the title of the file stored in the file storage unit 41 and a main keyword directly related to the file of the title identified by the title ID are identified. “Main keyword ID” is associated with each other.

  In the main keyword correspondence table of FIG. 6, “T00005” is registered as the title ID. The file of the title “Gianz's famous players” (FIG. 5) identified by the title ID “T00005” is the main keyword “N Shima S male” registered in the main keyword ID table of FIG. “O S cure” and the main keyword “K Kami T cure” are directly related main keywords. Therefore, in the main keyword correspondence table of FIG. 6, the title ID “T00005” is the main keyword ID “D00003” and the main keyword “O S” associated with the main keyword “N Shima S male” in the main keyword ID table. The main keyword ID “D00001” associated with “Osamu” and the main keyword ID “D00016” associated with the main keyword “Koji Tji”.

  Next, FIG. 7 is a flowchart for explaining processing for registering a file in the file server 11 of FIG.

  For example, when the communication unit 20 receives a file to be registered in the file server 11 via a network (not shown) and supplies the file to the file control unit 33, in step S11, the file control unit 33 causes the communication unit 20 to The file supplied from is stored in a predetermined directory of the file storage unit 41, and the process proceeds to step S12.

  In step S12, the file control unit 33 displays a screen for inputting a file title on the display 52, and prompts the user to input the file title stored in the file storage unit 41 in step S11.

  When the user operates the keyboard 51 and inputs the title of the file stored in the file storage unit 41, the keyboard 51 supplies the title input by the user to the file control unit 33. The file control unit 33 generates a title ID for identifying the title input by the user, and displays the title input by the user and the file path indicating the path of the file stored in the file storage unit 41 together with the title ID. To the database engine 32. The database engine 32 stores the title ID, title, and file path in association with each other in the title table of FIG. 5 stored in the table storage unit 42.

  The file control unit 33 supplies the title and the file path together with the title ID to the database engine 32, and then displays a screen for inputting a keyword, which is information related to the file, on the display 52, and proceeds to step S13. Prompts for keywords.

  In step S13, when the user operates the keyboard 51 and inputs the first character of the keyword, the keyboard 51 causes the first character of the keyword input by the user (hereinafter referred to as input keyword as appropriate) to the file control unit 33. Supply. The file control unit 33 supplies the input keyword supplied from the keyboard 51 to the database engine 32.

  After the process of step S13, the process proceeds to step S14, and the database engine 32 determines whether or not the main keyword or sub-keyword that matches the input keyword is stored in the table storage unit 42.

  In the database engine 32, the main keyword that matches the input keyword in the forward direction is registered in the main keyword ID table of FIG. 3, or the sub keyword that matches the input keyword in the forward direction is registered in the sub-keyword correspondence table of FIG. For example, it is determined that the main keyword or sub-keyword that matches the input keyword in front is stored in the table storage unit 42. On the other hand, the database engine 32 does not register the main keyword that matches the input keyword in the main keyword ID table in FIG. 3 and the sub keyword that matches the input keyword in the sub keyword correspondence table in FIG. If it is not registered, it is determined that the main keyword or sub-keyword that matches the input keyword is not stored in the table storage unit 42.

  If it is determined in step S14 that the main keyword or sub-keyword that matches the input keyword is stored in the table storage unit 42, the process proceeds to step S15, and the database engine 32 stores the file stored in the file storage unit 41. A keyword (hereinafter, referred to as a candidate keyword as appropriate) that is a main keyword candidate directly related to the file is supplied to the file control unit 33.

  Here, if the main keyword that matches the input keyword is registered in the main keyword ID table of FIG. 3, the database engine 32 sets the main keyword that matches the input keyword as a candidate keyword to the file control unit 33. Supply.

  If the subkeyword that matches the input keyword is registered in the subkeyword correspondence table of FIG. 4, the database engine 32 acquires the main keyword ID that is associated with the subkeyword that matches the input keyword. To do. Then, the database engine 32 refers to the main keyword ID table of FIG. 3 and supplies the main keyword associated with the acquired main keyword ID to the file control unit 33 as a candidate keyword.

  Specifically, if the first character of the input keyword is “one”, the sub-keyword “single-hand method” registered in the sub-keyword correspondence table of FIG. The database engine 32 acquires the main keyword ID “D00001” associated with the sub-keyword “single-hand method”. Then, the database engine 32 refers to the main keyword ID table of FIG. 3 and supplies the main keyword “OS cure” associated with the main keyword ID “D00001” as a candidate keyword to the file control unit 33.

  After the process of step S15, the process proceeds to step S16, and the file control unit 33 supplies the candidate keyword supplied from the database engine 32 in step S15 to the display 52 for display, and the process proceeds to step S17.

  In step S <b> 17, the file control unit 33 determines whether the user has selected a candidate keyword displayed on the display 52.

  If it is determined in step S17 that the user has selected the candidate keyword displayed on the display 52, the process proceeds to step S18, where the file control unit 33 controls the database engine 32 to associate the main keyword ID with the title ID. Let them be attached.

  That is, when the user operates the keyboard 51 so as to select a predetermined candidate keyword displayed on the display 52, the keyboard 51 supplies an operation signal corresponding to the user's operation to the file control unit 33. The file control unit 33 specifies the candidate keyword selected by the user based on the operation signal from the keyboard 51, and supplies the candidate keyword to the database engine 32. Then, the database engine 32 refers to the main keyword ID table of FIG. 3 to acquire the main keyword ID associated with the main keyword that is the candidate keyword selected by the user, and the main keyword ID and step S12. Are associated with the title IDs generated in step 1, and stored in the main keyword correspondence table of FIG. After the process of step S18, the process is terminated.

  On the other hand, if it is determined in step S14 that the main keyword or sub-keyword that matches the input keyword is not stored in the table storage unit 42, the process proceeds to step S19, and the file control unit 33 performs the steps performed in the past. If the candidate keyword is displayed on the display 52 in S16, the candidate keyword is deleted, and the process proceeds to step S20. If the candidate keyword is not displayed on the display 52, the file control unit 33 skips step S19 and proceeds to step S20.

  If it is determined in step S17 that the user has not selected the candidate keyword displayed on the display 52, the process also proceeds to step S20.

  In step S20, the file control unit 33 determines whether or not the keyword input by the user has ended. For example, a button for instructing termination of keyword input is provided on the screen displayed on the display 52 in step S13, that is, a screen for inputting a keyword that is information related to a file. When the button is operated, the file control unit 33 determines that the keyword input by the user is finished.

  If it is determined in step S20 that the keyword input by the user has not been completed, the process returns to step S13, and thereafter, the processing from step S13 is repeated. As described above, the number of characters of the input keyword is increased by repeating the processing from step S13.

  On the other hand, if it is determined in step S20 that the keyword input by the user has been completed, the process proceeds to step S21, and the file control unit 33 selects either the main keyword ID table in FIG. 3 or the sub-keyword correspondence table in FIG. Whether to register the input keyword in.

  For example, the file control unit 33 displays a screen for designating the association of input keywords on the display 52, registers the input keyword as a new main keyword, and sets the input keyword to the already registered main keyword. The user is allowed to designate one of registration and registration. Then, the file control unit 33 determines whether the input keyword is registered in either the main keyword ID table of FIG. 3 or the sub-keyword correspondence table of FIG. 4 according to the user's specification.

  For example, when the user specifies that the input keyword is registered as a new main keyword, in step S21, the file control unit 33 determines to register the input keyword in the main keyword ID table of FIG. 3, and the process proceeds to step S22. .

  In step S22, the file control unit 33 generates a main keyword ID for identifying an input keyword which is a main keyword to be newly registered in the main keyword ID table of FIG. 3, and uses the main keyword ID and the input keyword. Correspondingly, it is registered in the main keyword ID table of FIG.

  After the process of step S22, the process proceeds to step S18, and the file control unit 33 controls the database engine 32 to associate the main keyword ID with the title ID. In this case, the database engine 32 associates the main keyword ID generated in step S22 with the title ID generated in step S12 and stores it in the main keyword correspondence table in FIG. After the process of step S18, the process is terminated.

  On the other hand, when the user designates that the input keyword is registered in association with the already registered main keyword, in step S21, the file control unit 33 determines to register the input keyword in the sub-keyword correspondence table of FIG. Then, the process proceeds to step S23.

  In step S23, the file control unit 33 displays a list of main keywords registered in the main keyword ID table of FIG. 3 on the display 52. From the list of main keywords displayed on the display 52, the input keyword is displayed. The user is prompted to select a main keyword to be associated with. When the user operates the keyboard 51 to operate the keyboard 51 so as to select a predetermined main keyword from the list of main keywords displayed on the display 52, the keyboard 51 receives an operation signal corresponding to the user's operation. Is supplied to the file control unit 33. The file control unit 33 specifies the main keyword selected by the user based on the operation signal from the keyboard 51, supplies the main keyword to the file control unit 33, and proceeds to step S24.

  In step S24, the file control unit 33 refers to the main keyword ID table of FIG. 3, acquires the main keyword ID associated with the main keyword supplied from the keyboard 51 in step S23, and the main keyword ID and The input keyword is associated and registered in the sub-keyword correspondence table of FIG.

  After the process of step S24, the process proceeds to step S18, and the file control unit 33 controls the database engine 32 to associate the main keyword ID with the title ID. In this case, the database engine 32 associates the main keyword ID associated with the input keyword in step S24 with the title ID generated in step S12 and registers it in the main keyword correspondence table of FIG. After the process of step S18, the process is terminated.

  As described above, in the file server 11, when the user registers a file in the file server 11, the main keyword already registered in the main keyword ID table of FIG. 3 is selected according to the input keyword input by the user. Present it to the user as a keyword. If the candidate keyword includes a keyword that the user associates with the content to be registered, the user selects the keyword, and thus the variation of the keyword with respect to a file having the same content can be suppressed.

  In addition, when the candidate keyword is not presented to the user, the user mistakenly registers the kanji of the same sound. Specifically, for example, the user should register “N island” as “N island”. I sometimes registered. On the other hand, in the file server 11, when the user inputs “N”, “N Shima” is presented to the user as a candidate keyword, so that the user is prevented from registering the kanji with the same sound by mistake. The

  Further, by suppressing variations in keywords as described above, it is possible to reduce the storage capacity of the storage unit 19 used for registering keywords as compared with the case where keywords are stored in a dispersed manner.

  FIG. 8 is a flowchart for explaining processing for searching for a file registered in the file server 11.

  The file control unit 33 displays a screen for inputting a search keyword used for searching for a file on the display 52 according to a user operation, and prompts the user to input the search keyword in step S31.

  When the user operates the keyboard 51 to input one character as a search keyword, the character is supplied from the keyboard 51 to the file control unit 33. In step S <b> 32, the file control unit 33 supplies the database engine 32 with a search keyword that is a sequence of characters supplied from the keyboard 51 so far. The database engine 32 determines whether the main keyword or sub-keyword that matches the search keyword supplied from the file control unit 33 is stored in the table storage unit 42.

  In the database engine 32, the main keyword that matches the search keyword in the forward direction is registered in the main keyword ID table of FIG. 3, or the sub keyword that matches the search keyword in the forward direction is registered in the sub-keyword correspondence table of FIG. For example, it is determined that the main keyword or sub-keyword that matches the search keyword in front is stored in the table storage unit 42. In contrast, the database engine 32 does not register the main keyword that matches the search keyword in the main keyword ID table in FIG. 3 and the subkeyword that matches the search keyword in the subkeyword correspondence table in FIG. If it is not registered, it is determined that the main keyword and sub-keyword that match the search keyword in front are not stored in the table storage unit 42.

  If it is determined in step S32 that the main keyword or sub-keyword that matches the search keyword in advance is stored in the table storage unit 42, the process proceeds to step S33, and the database engine 32 determines the file to be presented to the user as the search result. The title is supplied to the file control unit 33.

  That is, if the main keyword that matches the search keyword is registered in the main keyword ID table of FIG. 3, the database engine 32 acquires the main keyword ID associated with the main keyword that matches the search keyword. To do. If the subkeyword that matches the search keyword is registered in the subkeyword correspondence table of FIG. 4, the database engine 32 acquires the main keyword ID that is associated with the subkeyword that matches the search keyword. To do.

  Then, the database engine 32 refers to the main keyword correspondence table in FIG. 6 to obtain the title ID associated with the obtained main keyword ID, and refers to the title table in FIG. The associated title is supplied to the file control unit 33 as the title of the file presented to the user as a search result.

  After the processing of step S33, the process proceeds to step S34, and the file control unit 33 supplies the title supplied from the database engine 32 in step S33 to the display 52, and displays the title as a search result on the display 52, and step S35. Proceed to

  In step S <b> 35, the file control unit 33 determines whether the user has selected the title displayed on the display 52.

  When the user operates the keyboard 51 so as to select a title displayed on the display 52, the keyboard 51 supplies an operation signal corresponding to the user's operation to the file control unit 33. Based on the operation signal from the keyboard 51, the file control unit 33 determines that the user has selected the title displayed on the display 52, and proceeds to step S36.

  In step S36, the file control unit 33 specifies the title selected by the user based on the operation signal supplied from the keyboard 51 in step S35, and supplies the title to the database engine 32. The database engine 32 refers to the title table in FIG. 5 and supplies the file path associated with the title supplied from the file control unit 33 to the file control unit 33. The file control unit 33 reads the file from the file storage unit 41 based on the file path supplied from the database engine 32, supplies the file to the display 52, displays it, and ends the process.

  On the other hand, if it is determined in step S32 that neither the main keyword nor the sub-keyword that matches the search keyword is stored in the table storage unit 42, the process proceeds to step S37.

  If it is determined in step S35 that the user has not selected the title displayed on the display 52, the process also proceeds to step S37.

  In step S37, the file control unit 33 determines whether or not the input of the search keyword by the user has been completed. For example, a button for instructing the end of the input of the search keyword is provided on the screen for inputting the search keyword displayed on the display 52 in step S31, and when the user operates the button, The control unit 33 determines that the input of the search keyword by the user has been completed.

  If it is determined in step S37 that the input of the search keyword by the user has not been completed, the process returns to step S31, and thereafter, the processing from step S31 is repeated. As described above, the number of characters of the search keyword increases by repeating the processing from step S31.

  On the other hand, if it is determined in step S37 that the keyword input by the user has been completed, the process proceeds to step S38, and the file control unit 33 performs a search using the search keyword input by the user, and as a result, the file is not found. Is displayed on the display 52, and the process ends.

  As described above, in the file server 11, when the user searches for the file registered in the file server 11, not only the main keyword directly related to the file but also the search keyword input by the user, Since the sub-keyword related to the main keyword is also a search target, the probability that a desired file is output as a search result can be improved. Thereby, the time for the user to search for a desired file can be shortened.

  Specifically, for example, in the main keyword correspondence table of FIG. 6, the title ID of the video file of the game in which “N Shima S Male” participates identifies the main keyword “N Shima S Male”. Is associated with the main keyword ID “D00003”, and the sub-keyword correspondence table of FIG. 4 includes the sub-keyword “Mister Gains”, which is the nickname of the main keyword “N Shima S male”, and the main keyword “N”. It is assumed that the sub-keyword “N island” having the same sound as “Sima Shima” is associated with the main keyword “D00003” for identifying the main keyword “N Shima S”.

  Then, when the desired file is a video file of a game in which “N Shima S Male” participates, the user is not only “N Shima S Male” but also “N Shima S Male”. Even if “M Island Gains” or “N Island” with the same sound as “N Island” is input as a search keyword, a file of a game in which “N Island S Male” participates is output as a search result.

  Further, in the file server 11, since the variation of the keywords stored in the storage unit 19 is suppressed, the amount of data to be searched for the search keyword is reduced compared with the case where the keywords are stored in a dispersed manner. Thus, the search speed can be improved.

  In addition to the case where the input keyword matches the main keyword or sub-keyword in front, for example, when the input keyword matches back to the main keyword or sub-keyword, or the input keyword is included in the main keyword or sub-keyword. In such a case, it may be determined that the input keyword matches the main keyword or the sub keyword. Further, the similarity between the input keyword and the main keyword or the sub keyword may be obtained, and based on the similarity, it may be determined whether or not the input keyword is suitable for the main keyword or the sub keyword.

  In addition, the file may be associated with the keyword other than when the file is registered in the file server 11. For example, a file already stored in the file storage unit 41 is designated, , Keywords can be associated.
