  FIG. 2 is a functional block diagram showing each function realized by the operation of the control unit 10 of the file server device 1 in the present embodiment. The control unit 10 functions as the document management unit 101, the score calculation unit 102, and the list creation unit 103 by reading and executing the control program 1P. In addition to the document file 111, an update log database (DB: Data Base) 112, a browsing log DB 113, a search log DB 114, an access log DB 115, and a display list DB 116 are constructed in the storage unit 11 by each function of the control unit 10. An update log, a browsing log, etc. are recorded.

  The control unit 10 functions as the document management unit 101 to detect a document update request for each document file 111. The document update request is detected by the control unit 10 of the file server device 1 when, for example, the pasting process of the document file 111 and the overwriting / updating process of the document file 111 are performed via the application program corresponding to each document file 111. The The control unit 10 records an update log in the update log DB 112 of the storage unit 11 every time a document update request is detected. The update log recorded by the control unit 10 includes the update time acquired by the timer unit built in the control unit 10. Further, the update log includes difference data from the old document file or the old document file at the time when it was updated last time as the update contents in association with each document file 111. The update log may be associated with the ID of the user who updated the document file 111. Thereby, for example, the update log can be classified for each group to which the user belongs. Note that the update time may be information representing a time point updated by a time elapsed from a predetermined time point such as an operation start time point as the file server device 1.

  The control unit 10 functions as the document management unit 101 to detect a document browsing request for each document file 111. The document browsing request is detected by the control unit 10 of the file server device 1 when processing for opening the document file 111 is performed through an application program corresponding to each document file 111, for example. Each time the control unit 10 detects a document browsing request, the control unit 10 obtains and records the browsing time by a built-in timing unit, and also browses the browsing log DB 113 of the storage unit 11 including the contents of processing performed after browsing. To record. Like the update time, the browsing time may be information indicating a point in time when browsing is performed based on an elapsed time from a predetermined time. In addition, the browsing log may be associated with the ID of the user who executed the processing performed after browsing. Thereby, for example, the browsing log can be classified for each group to which the user belongs.

  The control unit 10 functions as the document management unit 101 to detect a search request for the document file 111. The search request is transmitted from the terminal devices 2, 2,. When the control unit 10 detects a search request, the control unit 10 extracts the document file 111 stored in the storage unit 11 based on the search condition transmitted together with the document file name, the extraction time, and the search extracted as a search result. The hit rank is set as one search log, and is recorded in the search log DB 114 for each keyword serving as a search condition. Similar to the updated time, the extraction time may be information representing a point of time extracted by an elapsed time from a predetermined time. At this time, the ID of the user who executed the search process may be associated. Thereby, for example, the search log can be classified for each group to which the user belongs.

  Further, the control unit 10 functions as the document management unit 101, so that none of the document update request, document browsing request, and search request for the document file 111 is detected, but when the path to the directory is created, the directory The access request to each document file 111 is detected when there is a request to output a list of document files 111 in the folder. When the document file 111 has not been browsed or searched, the control unit 10 stores, for example, the ID and access time of the user using the terminal device 2 that has transmitted the access request as one access log. 11 access log DB 115.

  Then, the control unit 10 functions as the score calculation unit 102 to calculate the score S indicating the degree of use for each document file 111. The calculation of the score S by the control unit 10 is performed periodically, for example, every predetermined period every day. Or the control part 10 is good also as a structure which calculates the score S, when it functions as the score calculation part 102 and it is judged that the update, browsing, and search were made frequently. In this case, whether updating, browsing, or searching is frequently performed is, for example, whether the number of times of browsing is greater than a predetermined browsing threshold, whether the number of times of searching is higher than a predetermined searching threshold, Alternatively, the determination is made based on whether or not the number of times of updating is greater than a predetermined update threshold value or whether or not all are satisfied.

  Moreover, the control part 10 functions as the score calculation part 102, and calculates the score S by the following formula | equation (1) and formula (2).

S = S1 * (S2 + S3) (1)
Here, S1 indicates the update frequency, S2 indicates the browsing frequency, and S3 indicates the number of times of search. In S1, S2, and S3, the frequency may be a frequency, and the frequency may be a frequency.

  In the present embodiment, as shown in Equation (1), the score S is calculated so that the update frequency S1 is a weight. However, the variable treated as the weight is not limited to the update frequency S1, and the score S may be calculated using the browsing frequency S2 and the number of searches S3 as the weight. Further, it may be possible to select whether the score S is calculated by using any one of the update frequency S1, the browsing frequency S2, and the search frequency S3 as a weight. For example, when a search condition is set when searching the document file 111 from the terminal device 2, the search condition input screen is configured so that a score S calculation method (weight) can be selected as one of the search conditions. .

  The update frequency S1 of the document file 111 may be calculated based on the number of updates to the document file 111 per unit time, that is, the number of update logs recorded during the unit time, but the file server device 1 according to the present embodiment. Then, it calculates by Formula (2) shown below.

S1 = k ₀ exp {− (k ₁ t ₁ + k ₂ t ₂ + k ₃ t ₃ )} (2)
However, k ₀ , k ₁ , k ₂ , and k ₃ are arbitrary coefficients.
t ₁ is t ₁ = current-last update time,
t ₂ is t ₂ = last update time−second latest update time,
t ₃ is t ₃ = 2nd latest update time−3rd newest time.
When calculating t ₁ , t ₂ and t ₃ , for example, they are calculated in units of hours.

  The update frequency S1 calculated by the equation (2) becomes larger as the update interval is shorter, and the score S calculated using the calculated update frequency S1 is more frequently updated, that is, the degree of use, that is, the importance level is increased. Highly calculated. On the other hand, depending on the search condition, the document file 111 that has not been updated to the latest state or the final version of the document file 111 may be important. In this case, since it is necessary to increase the score S calculated for the document file 111 with a low update frequency, the update frequency S1 is calculated by the following equation (3).

S1 = k ₀ [1-exp {− (k ₁ t ₁ + k ₂ t ₂ + k ₃ t ₃ )}] (3)
However, the definitions of the coefficients k ₀ , k ₁ , k ₂ , and k ₃ , t ₁ , t ₂ , and t ₃ are the same as those in Equation (2).

  When the update frequency S1 is calculated by the expression (3), the latest update time is old and the document file 111 that is determined to need to be updated, or the final version of the document that is not frequently updated during creation The value of the score S calculated for a document file 111 that is a file 111 and that is frequently browsed or searched is larger. When configuring the search condition input screen so that the calculation method of the score S can be selected as one of the search conditions, it is configured so that the update frequency can be selected, and when the update frequency is selected The score S may be calculated from the update frequency S1 according to the equation (2), and the score S may be calculated from the update frequency S1 according to the equation (3) when low update frequency is selected. As a result, the user can search the desired document file 111 more efficiently with reference to the update frequency or the browsing frequency.

  The browsing frequency S2 of the document file 111 may be calculated by the number of browsing times per unit time for the document file 111, that is, the number of browsing logs per unit time. Further, the number of times of browsing viewed within the most recent predetermined period, for example, within one week, may be calculated as a ratio in the period (one week: seven days), or may be calculated by the same calculation method as equation (2). . The number S3 of times the document file 111 has been searched may be the number of times the document file 111 has been extracted based on the search conditions in the past. It should be noted that the counting period of the number of times of retrieval may be the latest predetermined period (for example, three months).

  The control unit 10 records the score S calculated by the function as the score calculation unit 102 for each document file 111 by the function as the document management unit 101.

  When the search request from the terminal devices 2, 2,... Is detected by the function of the document management unit 101 and the document file 111 is extracted, the control unit 10 is extracted by functioning as the list creation unit 103. A document list is created by rearranging the document files 111 according to the value of the score S calculated for each document file 111. The control unit 10 transmits the created document list to the search request source terminal device 2 and records it in the display list DB 116 of the storage unit 11.

  Note that the control unit 10 may create the document list for each category. For example, the control unit 10 specifies the document file 111 having the largest score S value in the rearranged document file 111. The control unit 10 refers to the search log DB 114 for the specified document file 111, defines the most frequently used keyword as a category among the keywords input when the specified document file 111 is output as a search result, Classify the created document list. The control unit 10 may classify the created document list into the keyword category having the highest search hit rank. By classifying the document list into the keyword categories input at the time of the search in this way, when displaying the created document list, it becomes possible to display information on highly relevant keywords together, Makes it possible to search the desired document file 111 more efficiently.

  Next, functions implemented by the control unit 10 and each DB and information stored in the storage unit 11 by each function will be described with reference to content examples.

In the example shown in the explanatory diagram of FIG. 6, the update frequency S1 of the document file 111 of “Document 1” is “3”, the number of searches S3 is “5”, and the browsing frequency S2 is “2”. . The number of times of distribution is included in the frequency of browsing.

  In the example shown in the explanatory diagram of FIG. 6, the value of the score S calculated for the document file 111 of “Document 1” and the document file 111 of “Document 5” is larger than that of the other document files 111, and the document When the list 111 is created, it can be estimated that the list 111 is positioned at the top.

  Next, by the control unit 10 of the file server device 1 functioning as the document management unit 101, a process of recording an update log, a browsing log, a search log, and an access log in each DB, a process of calculating a score S, and Each procedure for creating a document list based on the records in each DB will be described with reference to flowcharts.

  FIG. 7 is a flowchart illustrating an example of a processing procedure for recording an update log, a browsing log, and a search log by the control unit 10 of the file server device 1 according to the present embodiment.

  The control unit 10 functions as the document management unit 101 to determine whether an access request to the document file 111 has been detected (step S101). When determining that the access request to the document file 111 is not detected (S101: NO), the control unit 10 returns the process to step S101.

  If the control unit 10 determines that an access request to the document file 111 has been detected (S101: YES), the control unit 10 determines whether the access request is a document update request (step S102). If the control unit 10 determines that the access request is not a document update request (S102: NO), the control unit 10 advances the process to step S105 described later. When the control unit 10 determines that the access request is a document update request (S102: YES), the control unit 10 collects update information including the update time and the updated content (step S103), and records the update information in the update log DB 112 as an update log. (Step S104).

  Next, the control unit 10 determines whether or not the access request to the document file 111 is a search request (step S105). If the control unit 10 determines that the access request is not a search request (S105: NO), the control unit 10 advances the process to step S108 described later. When it is determined that the access request is a search request (S105: YES), the control unit 10 collects search information including a search time, a search condition transmitted together with the search request, and a keyword input at the time of the search ( In step S106, the search log is recorded in the search log DB 114 as a search log (step S107).

  Next, the control unit 10 determines whether or not the document file 111 has been updated by an access request to the document file 111 (step S108). If the control unit 10 determines that there has been an update (S108: YES), since the update log is recorded, the process when the access request is detected is terminated.

  If the control unit 10 determines that there is no update (S108: NO), the control unit 10 determines whether the access request to the document file 111 is a document browsing request (step S109). When it is determined that the access request is a document browsing request (S109: YES), the control unit 10 collects browsing information including browsing time and processing after browsing (step S110), and records it in the browsing log DB 113 as a browsing log. (Step S111), and the process when an access request is detected is terminated. At this time, as for the processing after browsing included in the browsing information, the content of the processing may be unknown unless a certain time has elapsed after detecting the document browsing request. May be collected and a browsing log may be recorded.

  When the control unit 10 determines that the access request is not a document browsing request (S109: NO), the control unit 10 creates and records an access log (step S112), and ends the process when the access request is detected.

  As a result, access to the document file 111 such as overwriting, updating, searching, and browsing is recorded in each DB of the storage unit 11 as an update log, a search log, a browsing log, and an access log. Based on the frequency and the number of times, it is possible to calculate a score S representing the degree of use of each document file 111.

  Next, processing for calculating the score S of each document file 111 based on the update log, search log, and browsing log recorded by the processing procedure shown in the flowchart of FIG. 7 will be described. FIG. 8 is a flowchart illustrating an example of a score calculation processing procedure by the control unit 10 of the file server device 1 according to the present embodiment.

  The control unit 10 determines whether or not the number of searches in which the document file 111 is extracted as a search result is greater than a predetermined search threshold by the function as the document management unit 101 (step S21). If the control unit 10 determines that the number of searches is greater than a predetermined search threshold (S21: YES), the process proceeds to step S24 described later.

  When the control unit 10 determines that the number of searches of the document file 111 is equal to or less than a predetermined search threshold (S21: NO), the control unit 10 determines whether or not the number of times the document file 111 has been browsed is greater than a predetermined browse threshold. Judgment is made (step S22). If the control unit 10 determines that the number of browsing times of the document file 111 is greater than a predetermined browsing threshold (S22: YES), the control unit 10 advances the process to step S24 described later.

  When the control unit 10 determines that the number of times the document file 111 is viewed is equal to or less than a predetermined browsing threshold (S22: NO), the control unit 10 determines whether or not a predetermined time has elapsed since the score S was calculated most recently. (Step S23). When it is determined that the predetermined time has not elapsed (S23: NO), the control unit 10 returns the process to step S21.

  When the control unit 10 determines that the number of searches of the document file 111 is greater than a predetermined search threshold (S21: YES), the control unit 10 determines that the number of searches of the document file 111 is greater than a predetermined browsing threshold (S22: YES), or when it is determined that a predetermined time has elapsed (S23: YES), the following processing is performed by functioning as the score calculation unit 102.

  The control unit 10 calculates the update frequency S1 for each document file 111 from the update log DB 112 of the storage unit 11 (step S24). The update frequency S1 is calculated by the above equation (2). Next, the control unit 10 calculates the browsing frequency S2 for each document file 111 from the browsing log DB 113 of the storage unit 11 (step S25), and further calculates the number of searches S3 for each document file 111 from the search log 114 of the storage unit 11. (Step S26).

  The control unit 10 calculates the score S by the above equation (1) using the update frequency S1, the browsing frequency S2, and the search frequency S3 calculated in step S24, step S25, and step S26, respectively. It records in the memory | storage part 11 or the temporary memory area 12 (step S27), and the process which calculates the score S is complete | finished.

  Next, a process for creating a document list when the control unit 10 of the file server apparatus 1 detects a search request will be described. FIG. 9 is a flowchart illustrating an example of a processing procedure for creating a document list by the control unit 10 of the file server device 1 according to the present embodiment.

  The control unit 10 functions as the document management unit 101 to determine whether a search request for the document file 111 is detected (step S31). Even when the control unit 10 detects a list output request to output a list of document files 111 stored in an arbitrary directory or folder, the control unit 10 specifies “identify by directory name or folder name. It may be handled that the search request with the search condition “document file existing under the folder to be detected” is detected.

  When it is determined that the search request for the document file 111 is not detected (S31: NO), the control unit 10 returns the process to step S31. When the control unit 10 determines that a search request for the document file 111 has been detected (S31: YES), the control unit 10 extracts the document file 111 based on the search condition accompanying the search request (step S32).

  Then, when creating the document list of the extracted document file 111 by the function as the list creation unit 103, the control unit 10 reads the score S recorded for each document file 111, and extracts the document extracted based on the score S. The files 111 are rearranged (step S33). The control unit 10 creates a list of the rearranged document files 111 as a document list (step S34), transmits it to the terminal device 2 that requested the search request (step S35), and ends the process.

  When the control unit 10 creates the document list in step S34, the document file 111 extracted in step S32 is recorded with reference to the update log DB 112, the browsing log DB 113, the search log DB 114, and the access log DB 115. An update log is added as additional information. Further, when adding the update log as additional information, the control unit 10 includes information to be output when each document file 111 is instructed in association with each document file 111 as each item of the document list. . The document list transmitted from the file server device 1 may be configured to include a control statement for outputting additional information. Alternatively, when the terminal device 2 receives the document list and displays a list using each document file 111 of the document list as an item, if the mouse position is specified on the displayed item, additional information is output. It may be configured to do so.

  Further, since the control unit 10 determines whether or not a search request has been detected at step 105 in the processing procedure shown in the flowchart of FIG. 7, when the search request at this time is detected (S105: YES) ), The processing procedure (step S32 to step S35) shown in the flowchart of FIG. 9 may be performed, search information may be collected (S106), and a search log may be recorded (S107).

  Next, as described above, the file server device 1 records the update log, the browsing log, and the search log, and further calculates the score S, whereby the document list is received by the terminal device 2 and further displayed on the display unit 25. Each piece of information that can be grasped by the user in the case of being performed will be described. FIG. 10 is an explanatory diagram illustrating an example of a document list list displayed on the display unit 25 of the terminal device 2 constituting the document management system according to the present embodiment.

  As shown in the explanatory diagram of FIG. 10, when displaying a list of document files 111 recorded in the file server device 1 on the terminal device 2, an edit box 251 for inputting a keyword to be included in the search condition is displayed on the display unit 25. A list display area 252 for displaying a list of document files 111 included in the document list of the search result is displayed. In the example shown in the explanatory diagram of FIG. 10, “keyword 1” is input to the edit box 251 as a search condition, and the document file 111 of “document 1” is stored as a search result for the search condition including “keyword 1”. The contents of the document list with the search hit rank “1” are displayed in the list display area 252. In this case, an update log is associated with each document as additional information. Accordingly, when the user designates (mouse over or clicks) the file name of “document 1” in the list display area 252 of the display unit 25 and the vicinity thereof with the mouse of the operation unit 24, the window 253 is displayed. The window 253 may be in the form of a tool tip or in the form of a pop-up menu. In the window 253, the update log of the document file 111 of the instructed “document 1” is displayed as an update history. Specifically, the update time and the update contents, that is, the contents of the difference data are displayed as the update history. The contents of the difference data may be displayed when the user clicks each update time area with the mouse. The update time and the contents of the difference data are linked to the update log and the difference data corresponding to the update log in the file server device 1, and the detailed contents of the update log can be acquired when the user clicks with the mouse. The detailed contents of the difference data can be referred to. It is good also as a structure by which the size of the difference data which is the list | wrist of update history and the updated content is displayed.

  When displaying a list of document files 111 on the terminal device 2, if a list of file names is displayed in the list display area 252 and the user designates a file name and its neighboring range with a mouse, processing for the document file 111 is performed. The contents may be displayed. Processing contents include transfer, transmission, creation of a link, and the like of the document file 111.

  By realizing such a document management system, the update frequency, the browsing frequency, and the number of searches (frequency) are high when the search result is displayed even if the document file 111 shared by the organization is enormous. Since the document list in which the document files 111 are listed in order is displayed, the user can preferentially search for the document file 111 having a high degree of use.

  In the search, the user can select which of the update frequency S1, the browsing frequency S2, and the search frequency S3 is used as a weight to calculate the score S, so that the user can select the characteristics of the desired document file 111. The desired document file 111 can be searched more efficiently.

  Further, since the update history can be grasped for each of the document files 111 output as the search result, the user can update the document file 111 updated more frequently or the most important document updated most recently. The file 111 can be searched and found more quickly.

  As described above, the file server device 1 can manage the update log, the browsing log, the search log, etc. of each document file 111 stored in its own storage unit 11 (or a storage medium such as a connected storage device) by itself. Therefore, it is possible to calculate the score S for each document file 111 based on those logs. It is possible to calculate a score based on the number of searches, etc., even with a search method via the Internet or the like, but even if such a search method is applied, a score S reflecting the update frequency and the browsing frequency is calculated. While it is difficult to rank, the file server apparatus 1 according to the present embodiment can calculate the score S according to the update frequency, the browsing frequency, the search frequency, and the contents of the processing after browsing. It is effective in the point that can be done.
