To do. Hereinafter, an outline of processing performed in the document management system 1 according to the present embodiment will be described.

  The document management system 1 according to the present embodiment is an electronic document performed in a group including a plurality of persons in charge, an intermediate administrator who manages the persons in charge, and a senior administrator who manages the intermediate administrator. The report flow by is subject to processing. An example of the report flow will be described below.

  First, each of a plurality of persons in charge sets a report destination of a report (electronic document) created by the information processing terminal 3 as an intermediate manager, and registers the created report in the document management apparatus 2. The document management apparatus 2 provides the report created by each person in charge to the information processing terminal 3 of the intermediate manager who is the report destination of the registered report. The intermediate manager creates a summary report (electronic document) based on the report created by each person in charge, then sets the report destination of the created summary report as a senior manager and manages the summary report as a document. Register in the device 2.

  The document management device 2 evaluates and compares the ambiguity between the report created by each person in charge (person-in-charge report) and the summary report created based on those person-in-charge reports. Determine whether sex has changed. Here, when the document management apparatus 2 determines that the ambiguity has changed between the person-in-charge report and the summary report, there is a possibility that accurate information is not disclosed. For example, the senior manager who is the report destination of the summary report is notified of the change in ambiguity together with the report.

  Hereinafter, in order to implement | achieve the said process, the detail with which the structure with which the document management system 1 is equipped and the process performed in the said structure is demonstrated.

[flowchart]
Next, details of processing performed in the document management apparatus 2 will be described with reference to the flowcharts shown in FIGS.

[Report registration process]
FIG. 3 shows a flowchart of report registration processing by the document management apparatus 2.

  As shown in FIG. 3, when the document management apparatus 2 acquires an unregistered report from the information processing terminal 3 (S101), the document management apparatus 2 analyzes the acquired report (S102).

  For example, the document management apparatus 2 analyzes the acquired report and reports the report title, the report items included in the report, the user ID (creator ID) of the creator who created the report, and the report destination of the report The user ID (report destination ID), the ID of the report from which the report was created (preparation report ID), the report date and time, and the like may be acquired. The report title, creator ID, report destination ID, creator report ID, and report date / time may be set as attribute information in the report. Hereinafter, an example of processing for identifying the report items included in the report will be described.

  For example, the document management apparatus 2 has a case where the report is structured for each report item (for example, when described in XML or according to a predetermined layout (table structure, etc.)). Alternatively, a structured part of a report may be specified, and a report item may be specified based on a frequent relationship of words in each part. In addition, the document management device 2 reports on the basis of a known technique for recognizing a topic structure or a known technique for extracting a semantic group even if the report is not structured for each report item. The report items included in the document may be specified. Regarding the topic structure recognition processing, for example, a technique as shown in Japanese Patent Laid-Open No. 8-110906 is known, and the topic structure recognition specific word (topic word) in the report and the continuation range of the description about the word By recognizing (topic scope), it is possible to extract a report item and determine whether or not the same report item exists in a plurality of reports. Moreover, as a technique for extracting a semantic group, for example, Japanese Patent Application Laid-Open No. 2006-72483 is known, and a plurality of sentences that are semantically grouped are extracted by using a co-occurrence relationship between words and punctuation marks. To do. Based on the above processing, the document management apparatus 2 specifies the report items included in the report, and obtains a sentence (text data) corresponding to each report item in association with it.

  In addition, if the report originator report ID is not included as attribute information in the subject report, the originator of the subject report based on the information of the creator and reportee of the already registered report It is good also as specifying report ID. In this case, the document management apparatus 2 is a plurality of reports in which report destination IDs that match the creator ID of the target report are determined, and the reports registered within a predetermined time range. And the ID of the report whose report item corresponds to the target report among the extracted reports may be obtained as the creator report ID.

  The document management apparatus 2 registers the report information obtained based on the analysis result in the report registration table (see FIG. 7) (S103). Of course, the document management apparatus 2 may store the report itself in the storage unit 21.

  FIG. 7 shows an example of the report registration table. As shown in FIG. 7, the report registration table includes report identification information (report ID), report title, report item identification information (report item ID) included in the report, The user ID (creator ID), the report destination user ID (report destination ID), and the report date and time information are stored in association with each other.

  Next, the document management device 2 selects an unprocessed report item from the report items included in the report (S104), and evaluates the ambiguity of the report item based on the text data related to the selected report item. (S105). Hereinafter, an example of ambiguity evaluation of report items will be described.

  In the present embodiment, the document management apparatus 2 acquires one or more sentences included in text data related to a report item, and evaluates ambiguity based on each acquired sentence. For example, for each sentence related to the report item, the document management apparatus 2 specifies a specific (adjective) word including a deficiency in case structure (details will be described later), deficiency in dependency, and ambiguity. Evaluate the ambiguity of report items based on the presence or absence of For example, the document management device 2 has a deficiency in the case structure of a sentence related to a report item (judgment condition A), a deficiency in sentence dependency (judgment condition B), and a specific word including ambiguity in a sentence. When any of the included (determination conditions C) is satisfied, the report item may be evaluated as ambiguous (for example, T of truth value), and the determination conditions A to C are satisfied. The report item may be evaluated as ambiguous when the number of times or the number of times per sentence exceeds or exceeds a threshold. In addition, the document management apparatus 2 may evaluate the ambiguity by quantifying the evaluation based on the number of times that the determination conditions A to C for the text data related to the report item are satisfied (for example, the case structure is incomplete). 1 point if there is one). In this case, the document management apparatus 2 may use the total number of times the determination conditions A to C in the text data related to the report item are satisfied as the ambiguity of the report item, or per sentence in the text data related to the report item. The number of times the determination conditions A to C are satisfied may be set as the ambiguity of the report item.

Here, the case structure will be described. First of all, case grammar is a semantic relationship between words centered on verbs. The role of other words (deep case) for the verbs in a sentence is as follows. (See Charles J. Fillmore (translated by Harumi Tanaka, Michio Funagi): Principles of Case Grammar, Sanseido, 1975).
(1) Action principal: The role of a person who causes a certain action.
(2) Experienced personality: The role of a person experiencing a psychological event.
(3) Tools: A role that directly causes a certain event or acts as a stimulus that causes a reaction in relation to a certain psychological event.
(4) Object case: A role representing the content of a moving object, a changing object, or the contents of a psychological event such as judgment or imagination.
(5) Source case: A role that represents the starting point of movement of an object and the initial state and shape of the state change and shape change.
(6) Target case: A role that represents an end point in movement of an object, a final state in a state change and a shape change, and a result.
(7) Location: A role that represents the location and location where an event occurs.
(8) Time case: A role that represents the time at which a certain event occurs.
Here, one sentence forms a structure composed of one verb and a plurality of cases (this is called a case structure). Case structure analysis using a computer is based on the language theory and language processing technology described in, for example, the literature “Okada: Introduction to Natural Language Processing, Kyoritsu Publishing (1991)”. Morphological analysis, syntax analysis, meaning The case structure is analyzed by sequentially performing the analysis. As an analysis processing function of the same type, for example, conventional techniques as shown in, for example, Japanese Patent Laid-Open No. 63-097176 and Japanese Patent No. 2765618 are already known. The deficiency of the case structure may be determined based on, for example, whether there is a lack of a main case or a target case. Specifically, for example, in the sentence “Taro Yamada reports progress”, there are behavioral and objective cases, but there is a “time case” for when to report and a “target case” for who to report. The presence or absence of deficiencies is determined by detecting the lack. Moreover, it is good also as memorize | storing beforehand the combination of the verb used by the sentence of a report, and an essential case, and analyzing a case structure using this.

  Next, an example of a specific word including ambiguity will be described. Specific words that include ambiguity are based on whether specific adjectives such as “generally”, “pretty”, and “mostly” are set as a dictionary in advance, and whether these specific words are included in the sentence. It may be determined whether or not the sentence is ambiguous.

  Returning to the flowchart of FIG. The document management apparatus 2 registers report item information in the report item information table based on the results of the ambiguity evaluation for each report item included in the report (S106).

  FIG. 8 shows an example of the report item information table. As shown in FIG. 8, the report item information table stores report item identification information (report item ID), report item title, report item content, and ambiguity in association with each other.

  When there is an unprocessed report item regarding the report to be registered (S107: Y), the document management apparatus 2 returns to S104, and when there is no unprocessed report item (S107: N), further It is determined whether there is an unregistered report (S108). If there is an unregistered report (S108: Y), the document management apparatus 2 returns to S101. If there is no unregistered report (S108: N), the document management apparatus 2 ends the registration process.

  The above registration process may be executed each time the document management apparatus 2 receives a new report from the information processing terminal 3, or the unregistered information stored in the storage unit 21 at predetermined time intervals. It is also possible to carry out this report for other reports.

[Identification processing of report items subject to attention]
Next, with reference to the flowchart shown in FIG. 4, an example of a process for identifying a report item to be alerted among report items included in the report will be described.

  As shown in FIG. 4, the document management apparatus 2 refers to the report registration table, selects one unprocessed report from the summary reports (S201), and executes the following processing.

  The document management apparatus 2 selects one unprocessed report item IS from the report items included in the selected summary report (S202), and acquires the ambiguity of the selected report item IS from the report item information table. (S203). The report item of the summary report may be selected by sequentially selecting the report item ID stored in association with the report ID of the summary report in the report registration table. Further, the ambiguity about the selected report item IS may be obtained by associating the ambiguity (Vs) stored in the report item information table with the identification information (report item ID) of the report item IS.

  Next, the document management apparatus 2 identifies the report group of the creation source that is the basis for creating the summary report to be processed (S204). Note that the report ID of the report group of the creation source is stored in the column of the creation report ID of the report registration table in association with the report ID of the summary report.

  The document management apparatus 2 selects one unprocessed report Ri (i = 1 to M, the initial value is 1) from the report group G {R1,..., RM} of the creation source (S205). ) If the selected report Ri includes a report item corresponding to the report item IS (S206: Y), the degree of ambiguity stored in the report item information table for the report item is acquired (S206: Y). S207). Further, after S207, or when the report item corresponding to the report item IS is not included in the selected report Ri (S206: N), the document management apparatus 2 proceeds to S208. Here, when there is an unprocessed report in the report group of the creation source (S208: Y), the document management apparatus 2 returns to S205, and an unprocessed report in the report group G of the creation source. When there is no writing (S208: N), the process proceeds to S209.

  Here, the document management apparatus 2 determines the ambiguity Vs of the report item IS of the summary report and the ambiguity Vj (j = 1 to N) of the report item Ij (j = 1 to N) corresponding to the report item IS in the original report group. j = 1 to N) (S209), and as a result, whether the ambiguity has changed between the report item Ij included in the report group of the source and the report item IS included in the summary report It is determined whether or not (S210).

  For example, when the ambiguity is represented by a true / false value, the document management apparatus 2 compares the ambiguity Vs with the ambiguity Vj (j = 1 to N), respectively, and the number (A) It may be determined whether or not the degree of ambiguity has changed based on whether the ratio (A / N) is greater than or equal to the threshold. In addition, when the ambiguity is represented by a numerical value, the document management apparatus 2 has a number or a ratio of the difference between the ambiguity Vs and the ambiguity Vj (j = 1 to N) equal to or greater than the first threshold. Based on whether or not the second threshold value is exceeded or exceeded, it may be determined whether or not the ambiguity has changed.

  Here, when it is determined that the ambiguity has changed (S210: Y), the document management device 2 has information on the report item having the changed ambiguity (at least the report item IS and the report item Ij having the changed ambiguity). Group information) is recorded in the caution information recording table (see FIG. 9) (S211).

  FIG. 9 shows an example of the caution information recording table. In the example of the caution information recording table shown in FIG. 9, the report ID of the summary report, the report item ID of the report item included in the summary report, and the ambiguity change with respect to the report item ID of the summary report Information of the report item ID of the original report whose ambiguity has not changed is stored in association with the report item ID of the former report and the report item ID of the summary report. In the example shown in FIG. 9, the report item information is recorded for both the case where the ambiguity changes and the case where the ambiguity does not change, but the report item information is recorded only when the ambiguity changes. You may make it record.

  The document management apparatus 2 proceeds to S212 after S211 or when it is not determined that the ambiguity has changed (S210: N). Here, when there is an unprocessed report item for the summary report to be processed (S212: Y), the document management apparatus 2 returns to S202, and when there is no unprocessed report item (S212: N). ), The summary report to be processed is set as processed (S213).

  Next, when there is an unprocessed summary report (S214: Y), the document management apparatus 2 returns to S201, and when there is no unprocessed summary report (S214: N), the processing ends. To do.

  The above processing may be executed at the timing when the document management apparatus 2 acquires the summary report, or at the timing when the summary report transfer request or processing request is received from the information processing terminal 3, or may be determined in advance. It is good also as performing with respect to the summary report memorize | stored in the memory | storage part 21 for every time interval.

[Notice Information Notification]
Next, referring to the flowchart shown in FIG. 5, a process for notifying the user of a report item to be noted, which is performed by the document management apparatus 2, will be described.

  As shown in FIG. 5, the document management apparatus 2 specifies a summary report to be notified to the information processing terminal 3 (S301). For example, the document management apparatus 2 may specify a summary report related to the transfer request received from the information processing terminal 3 as a notification target.

  The document management device 2 refers to the caution information recording table, and if there is a report item whose ambiguity has changed among the report item IDs included in the identified summary report (S302: Y), the ambiguity changes. Attention information about the reported items is generated (S303). For example, the attention information may be information including a set of a report item of the summary report and a report item of the creation source report whose ambiguity has changed. For example, if the percentage of reports whose ambiguity has changed in the group of reports from which the summary report was created is less than or less than the threshold, information in the report from which the ambiguity has changed May be generated, and the percentage of reports with varying ambiguity in the group of reports from which the summary report was created exceeds the threshold. Alternatively, if it is larger, attention information indicating that the information may not be accurately reported in the summary report may be generated.

  Next, the document management apparatus 2 determines a notification destination for notifying attention information (S304). For example, the document management device 2 notifies at least one of a report destination and a creator defined for the summary report, a report destination and a creator defined for the report from which the summary report is created. You may choose to.

  Then, the document management apparatus 2 notifies attention information to the identified notification destination (S305). For example, the document management apparatus 2 may acquire the email address of the determined notification destination (user) from the user information management table, and transmit attention information to the acquired email address. Further, the document management apparatus 2 may transmit the summary report and the report from which the summary report is created together with the caution information.

  After notifying the attention information or when there is no report item whose ambiguity has changed for the summary report (S302: N), the document management apparatus 2 ends the processing.

  According to the document management apparatus described above, among the reports registered from the information processing terminal 3, report items whose information is not correctly disclosed are specified by using an ambiguous expression by the reporter.

  Further, the present invention is not limited to the above embodiment. For example, if the document management apparatus 2 determines that the report item is ambiguous in both the summary report registered from the information processing terminal 3 and the creation source report from which the summary report is based, It is also possible to record to that effect and notify at least one of the creator and reportee defined in at least one of the summary report and the report of the creator.
