Description

  The present invention relates to a document attribute management apparatus and a program.

  In recent years, there is a technique for automatically extracting a set of attribute names and attribute values described in a document by reading the document with a scanner or the like and analyzing the description content of the scanned document. For example, by causing a scanner to read a prescription used in a medical institution, a combination of an attribute name “doctor in charge” and an attribute value “Yoyama △ o” described in the prescription is extracted. Become. By using this technology, it is possible to automatically perform processing for adding attribute information of the scanned document to the scanned document and registering it in a predetermined document database of the document management system simply by reading the document with a scanner or the like. . A technique for automatically extracting a document title from a scanned document has been proposed (for example, Patent Document 1).

  By the way, medical institutions handle various types of documents such as referral letters, surgical consent forms, and inspection request forms in addition to prescriptions. Depending on the type of document, for example, various expressions such as an attending doctor and an examination requester may be used in addition to the above-mentioned doctor in charge as an expression for a doctor performing a medical practice.

JP 2006-251864 A JP 2006-092226 A Japanese Patent Laid-Open No. 2003-030218 JP 2003-330959 A JP 2004-078343 A

  However, in the data item registered in the database, for example, when the attribute name “primary physician” is used as an expression for a doctor who performs a medical practice, the attribute name “in charge doctor” is described in the newly read document. In this case, even if the attribute is the same for the document, the attribute name is different, so that it is treated as a different attribute item.

  An object of the present invention is to simplify the work of adding and registering attribute information to a file such as a document.

  The program according to the present invention includes a computer that stores the document type identification information and the actual attribute name that is the name of the attribute item when registering the attribute information extracted from the description content of the document in the attribute information storage unit. Real attribute name information storage means for associating and storing real attribute names of one or more attribute items to be described in each document belonging to the type, document type identification information, and attribute items described in the document Attribute name conversion information storage means for storing a conversion record including a pair of a read attribute name that is the name of the attribute and a real attribute name of the attribute item to which the read attribute name is assigned, a reading means for reading a document, and the reading Analyzing the document read by the means to extract the document type and a combination of the read attribute name and attribute value of the attribute item described in the document; and the attribute name conversion information storage means If it is determined that the reading attribute name of the document type extracted by the extracting unit does not match the actual attribute name, the attribute name converting unit converts the reading attribute name into the actual attribute name. The reading unit functions as a registering unit that registers the attribute information of the document read by the reading unit with the real attribute name in the attribute information storage unit.

  The attribute name conversion unit should convert the reading attribute name when the conversion record including the reading attribute name of the document type extracted by the extracting unit is not stored in the attribute name conversion information storage unit. It has a conversion record registration part which makes a user input a real attribute name, matches the inputted real attribute name, produces | generates a conversion record, and registers it in the said attribute name conversion information storage means.

  The document attribute information registration apparatus according to the present invention includes the identification information of the document type and the actual attribute name that is the name of the attribute item when registering the attribute information extracted from the description content of the document in the attribute information storage unit. Real attribute name information storage means for associating and storing real attribute names of one or more attribute items to be described in each document belonging to the document type, document type identification information, and the document type Attribute name conversion information storage means for storing a conversion record including a combination of a reading attribute name that is the name of the attribute item and a real attribute name of the attribute item to which the reading attribute name is attached, and a reading means for reading a document Analyzing the document read by the reading means, and extracting means for extracting the document type and a combination of the read attribute name and attribute value of the attribute item described in the document; and the attribute name Conversion information storage means Referring to the attribute name conversion means for converting the read attribute name into the real attribute name when it is determined that the read attribute name of the document type extracted by the extraction means does not match the real attribute name. And registration means for registering the attribute information of the document read by the reading means in the attribute information storage means with an actual attribute name.

  According to the first aspect of the present invention, the attribute information storage means stores the attribute name (reading attribute name) of the attribute item extracted from the read document even if the name of the attribute item is not unified depending on the type of document in the computer. It is possible to register after converting to the real attribute name which is the name of the attribute item when registering in the field.

  According to the second aspect of the present invention, even when the conversion record including the reading attribute name of the document type extracted by the extracting unit is not stored in the attribute name conversion information storage unit, the reading attribute name and the reading attribute A conversion record that associates the real attribute name of the attribute item with the name can be registered in the attribute name conversion information storage unit each time.

  According to the third aspect of the present invention, even when the attribute item names are not unified depending on the document type, the attribute name (read attribute name) extracted from the read document is registered in the attribute information storage unit. It is possible to register after converting to an actual attribute name which is the name of the attribute item at the time.

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

  FIG. 1 is a hardware configuration diagram of a computer forming a document attribute information registration apparatus 20 according to the present invention. The computer forming the document attribute information registration apparatus 20 in the present embodiment can be realized with a general-purpose hardware configuration such as a personal computer that has existed in the past. That is, as shown in FIG. 1, the computer is provided with a CPU 1, a ROM 2, a RAM 3, an HDD controller 5 connected to a hard disk drive (HDD) 4, a mouse 6 and a keyboard 7 provided as input means, and a display device. An input / output controller 9 for connecting each display 8 and a network controller 10 provided as a communication means are connected to an internal bus 11. In the present embodiment, a document database installed in the external document management server 40 is accessed. This access is performed via the network controller 10. In this embodiment, since a means for reading a paper document is necessary, a scanner 12 is further connected to the input / output controller 9.

  In the present embodiment, since the scanner 12 is used, the document attribute information registration device 20 is formed by connecting the scanner 12 externally to a computer. For example, an image forming device such as a multifunction machine equipped with a scanner is used. Thus, the document attribute information registration device 20 may be realized.

  Although there may be a difference in performance, since the document management server 40 is also a computer, its hardware configuration can be illustrated as in FIG.

  FIG. 2 is a block diagram of the document management system according to this embodiment. FIG. 2 shows the document attribute information registration device 20 and the document management server 40.

  The document attribute information registration apparatus 20 includes a document reading unit 21, a document analysis unit 22, an attribute name conversion unit 23, a document registration unit 24, a processing control unit 25, an actual attribute name information storage unit 26, and an attribute name conversion information storage unit 27. Have.

  The document reading unit 21 reads a document set on the scanner 12. The document analysis unit 22 analyzes the document read by the document reading unit 21 and executes the following processing using the built-in document type identification unit 28, attribute extraction unit 29, and real attribute name information registration unit 30. That is, the document type specifying unit 28 specifies the classification code from the read image of the document. The classification code is an identification code assigned to each type of document. The attribute extraction unit 29 extracts the attribute name and the attribute value described in the document from the read image as a set. The real attribute name information registration unit 30 registers the real attribute name information regarding the division code in the real attribute name information storage unit 26 when the user inputs and designates the division code. When the attribute name conversion unit 23 determines that the read attribute name of the document type extracted from the document analysis unit 22 by referring to the attribute name conversion information storage unit 27 does not match the actual attribute name, The read attribute name is converted into an actual attribute name. The document registration unit 24 instructs the database registration of the document by adding attribute information to the document read by the document reading unit 21 and transmitting the attribute information to the document management server 40. The processing control unit 25 performs overall operation control of the components 21 to 24. The real attribute name information storage unit 26 and the attribute name conversion information storage unit 27 store real attribute name information and attribute name conversion information described later, respectively.

  By the way, as described in the above description, in the present embodiment, two types of attribute names, that is, an actual attribute name and a read attribute name, appear. Here, the attribute name will be described.

  The “attribute information” handled in the present embodiment indicates information extracted from the description content of the document or a part of the information. In this embodiment, a case where the document management system is applied to a medical institution will be described as an example. However, in the medical institution, various types of documents such as a prescription, an introduction letter, an operation consent form, and an examination request form are handled. . For example, in a document called a prescription, information for specifying description items such as a patient ID, a patient's name, a medical department, an attending physician, a prescription drug, etc., which has been treated for a patient is printed, and an attribute value is written in an adjacent entry column. The In this way, by reading the information described in each document by printing or filling in with a scanner or the like, and analyzing the read image using existing technology, the name of the attribute item (in this prescription example, “patient ID” ”Or“ Physician ”) and attribute values as a pair. Thus, information related to the document obtained by reading the description items of the document is referred to as “attribute information” in the present embodiment, and this attribute information includes the name of the attribute item obtained from the read image. One or a plurality of pairs of the attribute item and the attribute value of the attribute item are included. The name of the attribute item extracted from the read document such as “patient ID” or “primary physician” is referred to as “read attribute name” in the present embodiment.

  On the other hand, in order to retain and manage the attribute value of each document in the document management system, the attribute item is assigned a name and managed. In this embodiment, a document to be managed and its attribute information are registered in the document database 42. As described above, the name of the attribute item when registering the attribute information in the document database 42 is used in this embodiment. In this form, it is referred to as “real attribute name”.

  When expressing a doctor who is in charge of medical treatment or treatment, it is different from the “primary physician” in the prescription, “inspection requester” in the examination request sheet, and “in charge doctor name” in the surgical consent form. Therefore, even if it is an attribute item indicating information of a doctor, the reading attribute name is different from “primary physician”, “examination requester”, “in charge doctor name”, and the like. However, when the attribute item indicating the same information as a doctor is managed in the database, it is necessary to register all of the reading attribute names, for example, with the actual attribute name “physician”. The present embodiment is characterized in that an attribute name (reading attribute name) whose expression varies depending on a document is converted into an actual attribute name so that attribute information can be registered in the document database 42.

  The components 21 to 25 in the document attribute information registration apparatus 20 are realized by a cooperative operation between a computer that forms the document attribute information registration apparatus 20 and a program that operates on the CPU 1 installed in the computer. The real attribute name information storage unit 26 and the attribute name conversion information storage unit 27 are realized by the HDD 4 or the RAM 3 mounted on the document attribute information registration device 20.

  The document management server 40 is a server used for overall management of documents handled by this system. The document database 42 stores the document and attribute information of the document. The document management unit 41 performs overall management of information stored in the document database 42 such as information registration for information on new documents, information update and deletion of existing documents, and notification of information in response to external inquiries. The document management unit 41 is realized by a cooperative operation of a server computer forming the document management server 40 and a program operating on a CPU mounted on the server computer. The document database 42 is realized by the HDD 4 mounted on the document management server 40.

  FIG. 3 is a diagram showing a data configuration example of attribute information registered in the document database 42 in the present embodiment. The attribute information registered in the document database 42 is set for each document, and includes attribute items indicated by actual attribute names such as a document name, a document classification, a patient ID, a patient name, a medical department, and an attending physician. Among these, the document classification is an identification code assigned to specify the type of the document.

  FIG. 4 is a diagram showing a data configuration example of the real attribute name information stored in the real attribute name information storage unit 26 in the present embodiment. The actual attribute name information is set for each document category, and the title assigned to the document category in common with the document belonging to the document category and one or more attributes to be described in the document belonging to the document category Item names (actual attribute names) are set in association with each other.

  In this embodiment, for example, each document belonging to the type of document called an examination request sheet may have a plurality of formats. Since it is assumed that “user” is used, the real attribute name information is set in association with the real attribute name for each category for specifying the document type.

  FIG. 5 is a diagram showing a data configuration example of the attribute name conversion information stored in the attribute name conversion information storage unit 27 in the present embodiment. The attribute name conversion information is set for each attribute item, and includes the document category, the name of the attribute item (read attribute name) commonly used for documents belonging to the document category, and the attribute with the read attribute name. The attribute item name (actual attribute name) used when the item is registered in the database is set as a set. The attribute name conversion information corresponding to each document category is also referred to as a conversion record.

  The program used in this embodiment can be provided not only by communication means but also by storing in a computer-readable recording medium such as a CD-ROM or DVD-ROM. The program provided from the communication means or the recording medium is installed in the computer, and various processes are realized by the CPU of the computer sequentially executing the installation program.

  Next, processing for registering document attribute information in the database in the present embodiment will be described with reference to the flowcharts shown in FIGS.

  First, when a user sets a paper document to be registered in the scanner 12 and performs a predetermined reading operation, the document reading unit 21 reads the paper document using the scanner 12 (step 100). The document type specifying unit 28 in the document analyzing unit 22 extracts and specifies the document classification code described in the document by analyzing the read image using the existing technology (step 101). If the document classification cannot be specified from the read document, the user may specify a document classification code using a document type designation screen described later. In addition, the document name is extracted together with the document classification. If the document name cannot be extracted, the document name can be acquired by sending a document name acquisition request including the document classification to the document management server 40. Subsequently, the attribute extraction unit 29 in the document analysis unit 22 analyzes the read image using existing technology, and extracts attribute names and attribute values described in the document as a set (step 102). Then, the document analysis unit 22 displays a document registration confirmation screen for displaying the extracted information on the display 8 (step 103). FIG. 8 shows a display example of the document registration confirmation screen in the present embodiment. As shown in this display example, the document registration confirmation screen includes the document classification and document name acquired by the above processing, and an attribute name (read attribute). Name) and attribute value are displayed in pairs.

  Here, when the user wants to change the document type that can be confirmed by the document category and / or the document name because it is different from the desired document category, the document type change button 36 is displayed, and the reading attribute name is different from the actual attribute name. If it is desired to register additional conversion records in the attribute name conversion information storage unit 27 because it knows in advance that it is not registered in the attribute name conversion information storage unit 27, the attribute addition button 35 is read as it is. When the document may be registered in the database, the registration button 37 is selected. First, when the user selects the document type change button 36 (“change document type” in step 104), the document type specifying unit 28 displays a document type designation screen on the display 8.

  FIG. 9 is a diagram showing an example of a screen for displaying the document type to which the document to be processed belongs in the present embodiment. On this screen, a display area 51 for displaying the document classification and document name before change extracted in step 101, an input area 52 for inputting the document classification to be changed, and when the document classification is input Corresponding to the document classification, a display area 53 for displaying the document name acquired from the document management server 40 is provided. When the user inputs a document category in the input area 52 and selects the change button 54, the document type identification unit 28 changes the document category (step 105). Then, the document analysis unit 22 displays the changed document classification on the document registration confirmation screen (step 103).

  If the user selects the attribute addition button 35 (“add attribute” in step 104), the process control unit 25 causes the attribute name conversion unit 23 to execute an attribute name addition process (step 106). This process will be described with reference to the flowchart shown in FIG.

  The attribute name conversion unit 23 first displays an attribute addition screen on the display 8 (step 121). FIG. 8 is a diagram showing a display example of the attribute addition screen in the present embodiment. In FIG. 8, a display area 56 for displaying a list of reading attribute names and a display area 57 for displaying a list of actual attribute names are provided. The read attribute name displayed in the display area 56 is acquired from the document analysis unit 22. The real attribute name displayed in the display area 57 can be acquired by sending a real attribute name acquisition request including the document classification acquired from the document analysis unit 22 to the document management server 40. Then, after selecting the reading attribute name and the actual attribute name associated with the user one by one, the attribute addition button 58 is selected. In this way, upon receiving a set of reading attribute names and real attribute names associated with the reading attribute names (step 122), the conversion record registration unit 31 associates document classifications with these sets of attribute names. A conversion record is generated and registered in the attribute name conversion information storage unit 27 (step 123). Upon confirming the end of the attribute name conversion process, the process control unit 25 causes the document analysis unit 22 to display a document registration confirmation screen (step 103).

  When the user selects the registration button 48 (“Register” in Step 104), the process control unit 25 causes the attribute name conversion unit 23 to execute attribute conversion processing described later. At this time, the document analysis unit 22 extracts the real attribute name corresponding to the document classification from the real attribute name information storage unit 26, and the real attribute name, the read attribute name, the document classification, and the read image to the attribute name conversion unit 23. hand over.

  First, the attribute name conversion unit 23 compares one of the read attribute names received from the document analysis unit 22 with the actual attribute name (step 107). Here, if there is a real attribute name that matches the reading attribute name (Y in step 108), if there is a reading attribute name that has not been compared (Y in step 114), comparison of the reading attribute name is performed. The process proceeds (step 107).

  If there is no real attribute name that matches the read attribute name as a result of the comparison between the read attribute name and the real attribute name (N in step 108), the attribute name conversion unit 23 uses the document classification and the read attribute name as a key for the attribute. The name conversion information storage unit 27 is searched. Here, when there is a conversion record in which the document classification and the reading attribute name are set (Y in Step 110), the attribute name conversion unit 23 converts the reading attribute name into the actual attribute name included in the conversion record (Step S110). 112). On the other hand, when there is no corresponding conversion record (N in Step 110), the conversion record registration unit 31 in the attribute name conversion unit 23 performs an attribute name addition process (Step 111). Since this processing has been described above, the description thereof will be omitted, but this attribute name addition processing is generated by associating the document classification with the set of the read attribute name to be processed and the real attribute name specified by the user. The conversion record is registered in the attribute name conversion information storage unit 27. Then, the attribute name conversion unit 23 converts the read attribute name into an actual attribute name included in the conversion record (step 112).

  The above processing is repeated for all reading attribute names (step 113). Through the above processing, the reading attribute name that matches the actual attribute name is not converted as it is, and the reading attribute name that does not match the actual attribute name is converted to the actual attribute name according to the attribute name conversion information. The names of the attribute items to be used are all real attribute names.

  Then, the document registration unit 24 forms attribute information including a pair of an actual attribute name and an attribute value and a document classification, adds the information to the read document, and sends it to the document management server 40 to issue a document registration instruction. When the document management unit 41 in the document management server 40 receives the document registration instruction from the document attribute information registration apparatus 20, the document management unit 41 associates the attribute information with the document and registers it in the document database 42 (step 114).

  In the present embodiment, the case where the present invention is applied to a medical institution has been described as an example, but it goes without saying that the present invention can be applied to other institutions and fields.
