Abstract

PURPOSE:To reduce document logical structure designing operation and to decrease operation misses. CONSTITUTION:A request acceptance part 1 accepts a structure designing assistance request from a document designer and passes the name of a document to be designed to a logical structure conversion part 5. The logical structure conversion part 5 once obtaining the name of the document to be designed searches for a document having the same name as the received document name among documents in a structured document storage part 2. Then information showing the process object included in the document is utilized to generate logical objects corresponding to all process object parts on logical structure. Then information specifying the description of the process object part described in a group of pieces of information in the process information holding part 3 is changed into the identifier of the logical objects. Lastly, the name of the document to be designed is passed to a logical structure generalization assistance part 5. The logical structure generalization assistance part 5 once actuated to to obtain the name of the document to be designed after the logical structure conversion part 5 ends obtains a process information list holding the document name as one of input/output document names from a process information holding means 3 and displays it to the designer.

2. Description of the Related Art In constructing a document creation work support system using structured documents, a document is prepared in advance so that the system can automatically identify the target of the document processing determined based on the features of the work. A logical structure must be given. Hereinafter, such a logical structure providing operation will be referred to as a document logical structure designing operation.

Conventionally, in an assistive technology related to the logical structure design work of a document, an approach is to prepare all the information necessary for determining the logical structure in advance and then automatically generate the structure by using such information. It was being done. For example, in Japanese Patent Laid-Open No. 05-159101 ("Device and method for document logical structure and document content recognition"),
From the hardcopy document, the document layout information and
A method of giving a logical structure to a document by using a relationship (structural model) between a document logical structure and a layout structure given in advance is shown. On the other hand, in many cases, the information necessary for determining the logical structure in such a design work and its usage method become clear in the designer's head only as the design work progresses.

For example, in a document creation task in which a process such as deleting or copying is performed on a part of paragraphs, charts, and chapters in a document, and the process content is determined for each target, Consider the case where additions and deletions occur relatively frequently and suddenly. In addition, it is assumed that a policy of "guaranteeing correct processing of the system and at the same time suppressing edit restrictions imposed on the user to a minor one" is given as a design policy of a system that supports this work.

As a mechanism that can be considered when constructing this system, a tag holding the processing content is held as a logical object in the document logical structure, and the positional relationship in the logical structure between the tag and the design target itself is uniquely determined. Consider that the system is given only this positional relationship. According to this mechanism, in order for the system to obtain the processing contents for the processing target, first the tag is searched from the logical structure, and the processing target is specified from the positional relationship held by the system itself,
It is possible to obtain the processing content for the processing target from the content of the tag.

An example of work for determining the positional relationship between this tag and the processing target itself is shown below. (1) First, obtain a design target determination policy based on the above design policy. Here, it is assumed that the policy of "preventing the addition / deletion work of the processing target from destroying the positional relationship" is obtained. (2) Next, consider the factors that govern the correlation between the addition / deletion work and the positional relationship. Here, "user interface of the editing device used in addition / deletion work" is considered as one of the factors. It is considered appropriate to cite this factor because it is considered that it is possible to prevent such an erroneous edit unless the edit that affects the positional relationship can be easily performed when the editing device is used. (3) Then, the designer can consider the factor and obtain the design result only after the factor is mentioned. Here, the document structure is designed so that addition / deletion work can be easily performed on the user interface of the editing apparatus, and at the same time, the positional relationship is determined so that the work of destroying the relationship by the user interface of the editing apparatus is difficult to perform. In addition, as the editing restriction imposed on the user, "do not destroy the positional relationship" will be mentioned.

Looking back on the above design work, the information (user interface of the editing device) used by the designer for designing the object (the positional relationship between the tag and the processing object itself) and its usage method are as follows: It becomes clear only when the information is used, and it becomes clear that it is difficult to predict the need in advance before it is used.

In order to support such a design work by the conventional technique, all situations in which the designer should make a decision are assumed, and all the information which is the material for the decision made in those situations is held in advance. (Japanese Patent Laid-Open No. 05-1
In the case of 59101, it is necessary to reflect it in the structural model in advance). However, as revealed above, it is difficult to predict in advance the need for information to be retained here. Therefore, the work required here is not realistic.

For this reason, such design work is currently performed manually using a structured document editing device or a general document editing device. However, this work places a heavy burden on the designer, and work errors tend to occur frequently.

[0010]

Therefore, according to the present invention,
It is an object of the present invention to provide a design support apparatus capable of reducing design work and work mistakes in the above document logical structure design work. The present invention aims to achieve this object by providing the following support. (1) Automatically assigning a logical object corresponding to a processing target portion in a document to a logical structure in advance before requiring a designer's judgment. (2) Of the information necessary for the designer's judgment, the input / output information and the processing content of the processing related to the document to be designed are immediately and automatically provided to the request of the designer.

[0011]

In order to achieve the above object, the structured document design support apparatus of the present invention comprises the following respective means. A request receiving unit (1 in FIG. 1) that receives a designer's support request and obtains a design target document name, and a structured document holding unit that holds a design target structured document group including information indicating a target portion of document processing. (2) The document of the structured document holding means is set as one of the input / output documents, and the set of information and the processing content designating the description of the processing target portion in the input / output document is set for each set in the same input / output document. A processing information holding unit (3) that holds a list in which the input and output document names are given as attributes in the list, receives the design target document name from the request receiving unit, and all the processing target portions of the document are document logic. Using the information indicating the processing target in the document data for the design target document in the structured document holding unit that holds the same name as the document name so as to correspond to the logical object in the structure, the logical structure At the same time as making a change, the logical structure converting means for converting the information designating the description of the processing target portion held in the processing information holding means corresponding to the changed portion of the logical structure into the identifier of the corresponding logical object (4) Receive the design target document name from the logical structure conversion means, obtain all lists holding the same name as the document name as one of the names of the input and output documents, and show it to the designer. Logical structure generalization support means (5).

[0012]

The request receiving means (1) receives the structural design support request from the document designer, and passes the design target document name to the logical structure converting means (4). Logical structure conversion means (4)
When the document name to be designed is obtained from the request receiving means (1), the document in the structured document holding means (2) is searched for a document having the same name as the received document name. Then
By using the information indicating the processing target included in the document,
A logical object corresponding to all processing target parts is generated on the logical structure. Next, processing information holding means (3)
The information designating the description of the processing target portion described in the information set (1) (for example, the serial number given corresponding to the description) is changed to the identifier of the (single or plural) logical object. Finally, the document name to be designed is passed to the logical structure generalization support means (5). The logical structure generalization support means (5) is started after the completion of the logical structure conversion means (4),
When the document name of the design target is received from, the processing information holding unit 3 holds the document name as one of the input / output document names and presents it to the designer. According to the present invention, in a document logical structure design involving a design judgment that cannot be assumed in advance, which occurs in the construction of a document creation work support system using a structured document, a logical object is made to correspond to a processing target portion in a document. It is possible to change the structure automatically. Further, it becomes possible to change the logical structure that occurs due to a trade-off between the content of document processing and editing work, while listing information about document processing to be performed on the work target. by this,
The work of the designer is reduced, and at the same time, the work mistakes are reduced.
You can build a higher quality system with less effort.

[0013]

FIG. 1 is a diagram showing the structure of a structured document design support apparatus according to an embodiment of the present invention. As shown in the figure, this structured document design support device comprises a request acceptance unit 1, a structured document holding unit 2, a processing information holding unit 3, a logical structure conversion unit 4, and a logical structure generalization support unit 5. . Each part will be described below. The request receiving unit 1 receives a structural design support request from the document designer, and passes the design target document name to the logical structure converting unit 4.

The structured document holding unit 2 holds a document to be designed (structured document). These documents are given names as identifiers. In addition, each document includes information that enables the system to identify the data corresponding to the portion to be processed. For example, a set of special data is embedded in the content part so as to sandwich a portion to be processed, and a serial number is sequentially assigned to the set of special data from the beginning of the document. Alternatively, a logical object corresponding to the processing target portion is prepared on the logical structure.

The processing information holding unit 3 is a structured document holding unit 2
The following sets of information are held for each processing target part (for example, the contents part held between the sets of the special data embedded in the document contents part) in the document processing between the documents held in. (1) Identifier of processing target part in input document (serial number or identifier of corresponding logical object) (2) Identifier of processing target part in output document (serial number or identifier of corresponding logical object) (3) Contents of document processing The set of information items is grouped as a list for each set of input / output document names in the process. That is, the same number of lists as the processes between documents are held in the process information holding unit 3. This list holds a set of input / output document names as attributes.

Upon receiving the document name to be designed from the request receiving unit 1, the logical structure converting unit 4 searches the documents in the structured document holding unit 2 for a document having the same name as the received document name. Next, the information indicating the processing target included in the document is used to generate the logical objects corresponding to all the processing target parts on the logical structure. Then, the serial number of the processing target portion described in the information set of the processing information holding unit 3 is changed to the identifier of the (single or plural) logical object. Finally, the document name of the design target is passed to the logical structure generalization support unit.

When the logical structure generalization support unit 5 receives the document name of the design object from the logical structure conversion unit 4, the processing information holding unit 3 holds a processing information list holding the document name as one of the input and output document names. Get from

FIG. 2 shows the work flow of the designer when the structured document logical structure design support apparatus having the above-mentioned configuration is used. As shown in FIG. 2, the work (3) is repeatedly performed in the design work. An example of the designer's work procedure is shown below. First, work (1) and work (2) are performed on all the document groups to be designed. After that, the work (3) is repeated for each document to be designed. Then, after the work (3) is completed for all the documents to be designed, it is determined whether or not all the problems are solved. As a result, if it is confirmed that all the problems are solved, the design work is completed. The contents of each work in FIG. 2 and the usage environment of the structured document logical structure design support device in each work will be described below.

(1) Design target document and document flow determination, document structure logical structure provisional determination The designer prepares the data of all the design target documents, and holds information that clearly indicates the processing target portion in these data. Let Further, the processing information holding unit 3 holds all the processing information lists to be designed. Further, the designer adds a logical structure to the document to be designed. The logical objects of the given logical structure are set so as to correspond to paragraphs, figures, chapters and sections in the document. Then, all of these documents are held in the structured document holding unit 2. As a result of these operations, data required for the design operation is prepared in the structured document holding unit 2 and the processing information holding unit 3. An example of using the structured document logical structure design support device in this work is shown in FIG.

For example, when the design target document is given as an electronic document, the document designer uses the structured document editing device or the like to add the above logical structure to the document data. If the document to be designed is given in the form of a document, the document logical structure recognition device (Japanese Patent Laid-Open No. 05-159101) is used to digitize the document and add a logical structure. Then, the obtained structured document to be designed is stored in the structured document holding unit 2.

Next, the document designer uses the structured document holding unit 2
The special data in which serial numbers are given immediately before and immediately after the data corresponding to the portion to be processed is embedded in the inside document.
This allows the system to identify the data corresponding to the portion to be processed. In parallel with this work, corresponding processing information is created for each processing target portion in which the special data is embedded, using a document editing device or the like, and stored as a list in the processing information holding unit 3. However, there is a procedure other than the one described here for realizing the work (1).
For example, before the logical structure is added to the electronic document, information for identifying the data corresponding to the processing target portion may be added. Further, in order to add information for identifying the processing target data, a means other than embedding special data may be adopted. For example, only the portion to be processed may be extracted and held separately from the document data, and the information in the document data regarding the portion to be processed may be only the pointer to the portion to be processed.

(2) Conversion of the logical structure of the document plane The designer uses the document name (one or more) of the document in the structured document holding unit 2 as an argument to prepare a logical object corresponding to the portion to be processed. Then, a logical structure conversion request is issued to the request receiving unit 1. The request acceptance unit 1 accepts this request, and passes the document name which is an argument of the request to the logical structure conversion unit 4. The logical structure conversion unit 4 obtains the document data corresponding to the name of the argument from the structured document holding unit 2 for each document to be designed. Then, the logical structure of the obtained document data is converted. In response to this, the processing information holding unit 3
Change the information about the data to be processed. And
The design target document name is passed to the logical structure generalization support unit 5. As a result of these operations, a logical object corresponding to the processing target data is prepared on the logical structure of the design target document, and the identifier of the processing target data in the processing information holding unit 3 is converted into the identifier of the logical object. FIG. 4 shows a usage environment of the structured document logical structure design support apparatus in this work. In this work, the designer only issues a logical structure conversion request to the support device. All other work is done automatically by the support device.

(3) Generalization of Logical Structure of Document, Description of User Editing Restriction The logical structure generalization support unit 5 receives the name of the document to be designed from the logical structure conversion unit 4, and holds the name as an attribute value. The processing information list is found out from the processing information holding unit 3 and shown to the designer. The designer uses the structured document editing device or the like to modify the logical structure while looking at the processing information list shown. At the same time, a document editing device such as a general document editor is used to record restrictions on user editing that occur or change with the logical structure modification. As a result of these operations, the logical structure design that reflects the information described in the processing information list shown is performed for the document to be designed. At the same time, restrictions on user editing corresponding to the design result are described. FIG. 5 shows a usage environment of the structured document logical structure design support apparatus in this work.

When designing based on the flow of work shown in FIG. 2 using this apparatus, the contents of work performed in order and the information obtained as a result are sequentially shown. In the following, description will be made on documents A and B shown in FIG. Here, it is assumed that the document to be designed is not digitized and only the version of the document is available. In the present embodiment, the structured document design support apparatus is realized as a program on a UNIX workstation and data on a magnetic disk or memory. The request receiving unit 1 corresponds to a keyboard and a mouse, and a program for receiving a signal from the keyboard and the mouse. The structured document holding unit 2 and the processing information holding unit 3 correspond to a magnetic disk and a memory. A program corresponds to the unit 4, and a program and a display correspond to the logical structure generalization support unit 5.

(1) Document to be designed and document flow decision / temporary logical structure determination of document plane (obtaining document plane to design) Since the documents to be designed are document A and document B in FIG. First get the print.

(Tentative determination of document logical structure) Next, using the document logical structure recognition device, an electronic document is generated from each document version, a logical structure is added to the document, and the structured document holding unit 2
Save to. Here, it is assumed that the document logical structure recognition device can obtain the document logical structure shown in FIG. The character string "general matters" was recognized as a simple character string in the document A, while it was recognized as a headline in the document B.

FIG. 8 shows the manner of holding each document in the structured document holding unit 2 (adding information indicating the processing target to the document). It is assumed that each document is held as plain text on UNIX. Also, information regarding allocation in the file is omitted. FIG. 9 shows the result of adding information indicating the processing target to these documents.
The information indicating the processing target is a set of special symbols (“/ # 1 /”, “/ 1 /”, etc.) embedded in the document content section, and the processing target is the content section sandwiched between these special symbols. Shall be represented as Further, the processing information list corresponding to the processing between the document A and the document B is created. The created processing information list is shown in FIG.

(2) Logical Structure Conversion of Document Version First, the designer issues a logical structure conversion request holding "Document A" and "Document B" as arguments to the request receiving unit 1. Then, the logical structure conversion unit 4 obtains the “document A” and the “document B” from the structured document holding unit 2 and the corresponding processing information list from the processing information holding unit 3 and sandwiches them between the special symbol groups. So that the processing target corresponds to the logical object,
Convert logical structure. Further, the processing target identifier in the processing information list is converted into the identifier string of the corresponding logical object.

11 to 14 show the procedure of logical structure conversion and logical object identifier string extraction for each document. In the following description, “document data” means a character string corresponding to the content of a document and a special symbol for separating a processing target. In FIG. 11, first, the first character or symbol of the document data is set to the character string variable $ D.
It is set to ata (step S1). Then the string variable $
It is determined whether the content of Data is a start symbol or a terminal symbol. If No, the process proceeds to step S5. Y
If es, it is determined whether the content of the character string variable $ Data is the last document data of the content part included in the lowest object (step S3). If the result is Yes, the process proceeds to step S5. To do. If the determination result in step S3 is No, the lowest object corresponding to the character string variable $ Data is the lowest object corresponding to the document data up to the content of the character string variable $ Data and the content of the character string variable $ Data. Is exchanged with the lowest object corresponding to the document data immediately after (step S
4), the process proceeds to step S5. Subsequently, in step S5, it is determined whether the character string variable $ Data is the last document data, and if No, the next character or symbol of the document data is set in the character string variable $ Data (step S5).
6) and the process proceeds to step S2. If Yes, the procedure in FIG. 11 is completed and the process moves to “” in FIG.
When the procedure in FIG. 11 is completed, "start symbol" and "terminal symbol" exist only at the beginning or the end of the document data corresponding to the lowest object in the logical structure, and these "start symbol" and "terminal symbol" are present. The state in which the character string corresponding to the content of the document is divided by is eliminated.

In FIG. 12, the content of the character string variable $ Erase is first set to FALSE from the state of "" (step S7). Then, the LNR circulation [for example, the data structure (pp. 98-pp.
99), T.A. G. Levis M. Z. Smith, Translated by Shoji Ura, Baifukan (1987). In [Reference], the description of the identifier of the lowest arriving object is set in the character string variable $ ID (step S8). Subsequently, it is determined whether the document data corresponding to the lowest object indicated by the character string variable $ ID is composed of only the "start symbol" and the "terminal symbol".
Move to "". If Yes, it is determined whether the lowest object indicated by the character string variable $ ID is the lowest object that reaches first in the LNR tour (step S10). If the determination result in step S10 is Yes, the document data corresponding to the object indicated by the character string variable $ ID is added to the beginning of the document data corresponding to the lowest arriving object in the second in the LNR circulation (step S11) and the process proceeds to step S13, and if No, the character string variable $ I in the LNR circulation is used.
At the end of the document data corresponding to the lowest object that has arrived just before the object indicated by D, the character string variable $
Document data corresponding to the object indicated by the ID is added (step S12), and the process proceeds to step S13. In step S13, the content of the character string variable $ Erase is set to FALSE, and the process moves to "" in FIG.

In FIG. 13, from the state of "", it is first determined whether the object indicated by the character string variable $ ID is the last lowest object in the document (step S1).
4). If the determination result of step S14 is Yes, it is determined whether the content of the character string variable $ Erase is TRUE (step S15). If Yes, the last lowest object in the document is deleted (step S16). ), The procedure of FIG. 13 is completed, and the process moves to “” in FIG. If the determination result of step S15 is No, L for the logical structure
The lowest object identifier that arrives next to the character string variable $ ID in the NR cycle is set to the character string variable $ ID (step S17), and it is determined whether the content of the character string variable $ Erase is TRUE (step S18). . If Yes, the lowest object that has arrived immediately before the object indicated by the character string variable $ ID is deleted (step S1).
9), FALSE is set to the content of the character string variable $ Erase (step S20), and the process proceeds to step S9 via "" in FIG. If the determination result in step S18 is No, the process proceeds to step S9 via "" in FIG. When the procedure in FIG. 13 is completed, in addition to the state in which the procedure in FIG. 11 is completed, the lowest object corresponding to the document data consisting only of “start symbol” and “terminal symbol” is deleted.

In FIG. 14, from the state of "", first, a character string array @S holding the same number of elements as the number of objects to be processed is stored.
FALSE is set to the contents of all elements of "status" (step S21), and then the first character or symbol of the document data is set to the character string variable $ Data (step S2).
2). Following step S22, the character string variable $ Data
Is determined to be the start symbol (step S2
3) If YES, TRUE is set to the content of the character string variable $ Status [j] corresponding to the start symbol number j (step S24), and the process proceeds to step S29. If No, it is determined whether the content of the character string variable $ Data is a terminal symbol (step S25). If Yes, the character string variable $ S corresponding to the terminal symbol number k.
FALSE is set to the contents of status [k] (step S26), and the process proceeds to step S29. If the determination result of step S25 is No, the character string variable $ Da
It is determined whether the content of ta is data other than the control symbol at the beginning of the document data corresponding to the lowest object (step S27). If Yes, the character string variable $ Stat
Identifier of the lowest object corresponding to the character string including the character string variable $ Data as the last element of the array @ List-m having the character string as an element, for all m such that the content of us [m] is TRUE Is added (step S28), and the process proceeds to step S29. In step S29, it is determined whether the content of the character string variable $ Data is the last data of the document data. If No, the next character or symbol of the document data is set in the character string variable $ Data (step S30). , And proceeds to the processing of step S23. If the determination result of step S29 is Yes,
All the "start symbol" and "terminal symbol" in the document data are deleted and the work is finished.

When the procedure in FIG. 14 is completed, the identifier string of the logical object corresponding to the m-th processing target portion counted from the beginning of the document is obtained as an element of the character string array @ List-m. Also, all "start symbols" and "terminal symbols" in the document are deleted. Therefore, in order to convert the information designating the processing target in the processing information list into the identifier string of the logical object, for all the processing target identifiers, the character string array @Li corresponding to the identifier.
It suffices to exchange the concatenation of the descriptions of all the elements of st-m and the description of the processing target identifier. The document file format obtained as a result of these operations and the processing information list are shown in FIGS. The file format of the document obtained as a result of these operations and the processing information list are shown in FIGS. 15 and 16.

(3) Description of Generalization of Logical Structure of Document / Restriction of User Editing The logical structure generalization support unit 5 receives "Document A" and "Document B" from the logical structure conversion unit 4 and is shown in FIG. The processing information list is obtained from the processing information holding unit 3, displayed on the display, and shown to the designer. As a result, the designer can obtain the processing information about the document only by showing the document name of the design target to this device.

[0035]

As described above, according to the present invention, in the document logical structure design involving the unpredictable design judgment that occurs in the construction of the document creation work support system using the structured document, the document It is possible to automatically change the logical structure so that the logical object corresponds to the processing target portion. Further, it becomes possible to change the logical structure that occurs due to a trade-off between the content of document processing and editing work, while listing information about document processing to be performed on the work target. As a result, the work of the designer is reduced and at the same time, work mistakes are reduced, and a higher quality system can be constructed with less effort.
