Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for converting document information having a defined structure.

[0002]

2. Description of the Related Art As conventional technology (1),
Oh (ISO: International Standard Organizatio
ISO 8879: Information Processing ... Text and Office Systems ... Standard Generalized Markup Language (Information processing ... Tex)
t and office systems… Standard Generalized Marku
p Language: SGML) (ISO, 1986) (hereinafter abbreviated as SGML). According to this, a method of expressing the logical structure of a document as a hierarchical structure equivalent to a tree structure is shown. In addition, the common structure between multiple documents and the possible attributes of the constituent units are expressed as a document type definition (DTD: Document Type Definition), and each document specifies the type to which it belongs and It has a structure and attributes permitted by the type definition, and is expressed by setting attribute values for the attributes permitted by the document type definition.

The conventional technique (2) is a document type definition DT.
According to D, there is an implementation example of a structural document editing function that supports inputting and editing document contents. As an example,
One example is the SoftQuad program product, AuthorEditor. This is to specify the document type definition, input and edit the document,
You can enter the contents of the document example for each unit of the specified document type definition. Document content creation or modification operations that violate the specified structure of the document type definition are rejected. As a result, it is possible to efficiently create the document content according to the document type definition.

The conventional technique (3) is LaTex.
There is a function that the allocation format of the same document can be changed by preparing allocation style information that specifies the method of allocating document information such as, and using different allocation style information at the time of allocation. As a result, the output format of the document can be changed without changing the document body.

[0005]

The conventional technique (1) is
The method of expressing the logical structure of a document is shown, and the concept of expressing the format of each individual document example according to the class definition of the document, that is, the document type definition is shown.
However, it does not specify the relationship between document types.

The prior art (2) realizes the efficiency of creating a document example according to the document type definition and the function of associating with the visualization method and the allocation method, but different document type definitions. The function related to the conversion between documents that comply with the above has not been realized.

In the conventional technique (3), the allocation style information is changed for documents having the same logical contents.
Easily given output in different allocation formats. However, it does not change the structure between documents having different logical structures.

In the future, it is expected that the SGML document as described above will become widespread. In that case, a plurality of documents are provided for each document type definition which is a (logical) structural definition of a plurality of types of documents. Examples will be created. That is, the document type definition DTD (a) has the document example Doc (a-j). The document types DTD (a) and DTD (b) may be document type definitions of completely different documents, but may be document type definitions of related documents. For example, there are the following cases.

A) DTD (a) and DTD (b) are structurally equivalent and differ only in the name of the structural unit. B) DTD (a) is a rearrangement of DTD (b). C) DTD (a) is composed of a part peculiar to it and the whole of a plurality of document examples of DTD (b). D) DTD (a) is composed of a part specific to it and a part of the multiple document example of DTD (b).

Now, when the document example according to these document types is produced to some extent, the conversion request | requirement between related document types will generate | occur | produce. For example, if you want to change a paper created for one academic society to a paper for another academic society (see the example in (A)), if you want to create a summary that extracts only the title, author name, and abstract of a paper in a certain journal ( B)
When you want to compose one paper journal by collecting several papers according to the paper description procedure of an academic society and adding sentences in another format at the beginning and end (C) (See the example in (D)), or when it is desired to create a summary collection in which only the titles, author names, and abstracts of a plurality of articles described in a certain journal are created (see the example in (D)). It can be said that these requests are collectively requests for structural conversion of document information between document examples.

An object of the present invention is to convert the structure of document information from a source document example to a target document by utilizing the document type definition that the source document example follows and the document type definition that the destination document example should follow. To create an example.

A first object of the present invention is to provide a method in which a user specifies a correspondence between a conversion source document type definition and a conversion destination document type definition. More specifically, in order to deal with various cases as described above, a 1: 1 correspondence relationship between the constituent unit of the conversion source document type definition and the constituent unit of the conversion destination document type definition, the conversion source document type definition 1: 1 correspondence between some of the constituent units included and all or some of the constituent units included in the destination document type definition, constituent units included in the source document type definition Between the constituent unit sequence of the conversion source document type definition and the constituent unit of the conversion destination document type definition. The purpose is to make it possible to provide a correspondence relationship between them. In addition, when a plurality of occurrences are described as a definition of some constituent units of the conversion destination document type definition, the constituent unit or constituent unit sequence included in the conversion source document type definition is converted into It is an object of the present invention to provide a correspondence relationship that can be interpreted as an example of the appearance of one structural unit with a designated number.

A second object of the present invention is to create a conversion destination document example by converting an actually given conversion source document example according to the correspondence specified by the user.
Further, it is to provide an interface for passing the document contents converted in this way to a known structural document editing function.

[0014]

For the above-mentioned first object, the present invention provides a source document type definition which is a document type definition according to a source document example and a document type which is subject to a target document example. The conversion destination document type definition, which is the definition, is prepared, and the user is also provided with a means for associating the document type definitions with each other, and a means for creating the document type correspondence information indicating the designation result.

For the above second object, the present invention provides means for designating a conversion source document example and a conversion destination document type, referring to corresponding document type correspondence information, and creating a conversion destination document example. To do. It also provides means for passing the contents of the constituent units of the created conversion destination document to the structural document editing function.

[0016]

In order to achieve the above first object, according to the present invention, a conversion source document type definition which is a document type definition according to a conversion source document example and a conversion which is a document type definition according to a conversion destination document example. Prepare the destination document type definition, and use the matching operation between the document type definitions by the user, and use the appropriate conversion source document type definition constituent unit or series and the corresponding conversion source document type definition constituent unit. By specifying the correspondence relationship between and, it is possible to give a structural relationship between both document types. The specification of this correspondence is
It is possible to specify including the correspondence relationship corresponding to cases A) to D) described above. Document type correspondence information is created according to these specified results and saved as a form that is retrieved by the pair of the identification of the conversion source document type and the identification of the definition conversion destination document type definition so that it can be used in the following conversion processing. To

In order to achieve the second object, according to the present invention, a conversion source document example and a conversion destination document type are designated, and corresponding document type correspondence information is obtained by identifying the conversion source document type and the conversion destination document type. Can be extracted and referred to, and the conversion destination document example can be created while matching this with the contents of the conversion source document example. Further, every time a constituent unit of this conversion destination document example is created, its contents are passed to the structural document editing function, so that the document processing of the known structural document editing function such as editing and displaying while converting the conversion destination document example is performed. It is possible to use the function and to convert and add the contents from the conversion source document example to the existing conversion destination document example.

[0018]

FIG. 2 shows an example of the configuration of a document system which provides a method for converting the structure of document information according to the present invention. In FIG. 2, a processing device 20 is a processing device that executes a program that realizes this system, and a keyboard 21 is used by a user of this system to specify a document name and to respond to an inquiry from the system. The display device 22 is a character input means, an output device for displaying a document example and a document type definition, and the instruction input device 23 is a display device 22.
The external storage device 25 is an input device for giving a designation from the user by instructing the portion displayed on the screen. The external storage device 25 stores document data such as document examples, document type definitions and document type correspondence information, The main storage device 24 is a means for storing programs, and reads the program and document data of the present system from the external storage device 26 into the main storage device 24 as needed to refer to them by the program or generate / change data. This is a so-called main storage device.

When the system is started, a program for realizing the system is read from the external storage device 25 into the main storage device 24, and control is passed to this program.

The operation of this program will be described with reference to FIG. This program provides the document information structure conversion method of the present invention. When the program starts from the portion of reference numeral 100, first, in process 101, the display device 22 is displayed to ask the user what he / she wants to do, and the request is specified. The user is
The request is designated using the keyboard 21 or the instruction input device 23. There are two types of user's request: a case of associating between document type definitions and a case of structural conversion of document contents. The process 102 determines these, and if the former, the process proceeds to the process 111, and if the latter, the process proceeds to the process 121. The associating process between document type definitions starting from process 111 is the conversion source document type definition 13 which is input information.
1 and the conversion destination document type definition 132, the user is caused to perform a matching operation between both document type definitions, and the document type correspondence information 13
3 is created and stored in the external storage device 25.

Here, the document type definition, which is the premise of the description of the following processing, will be described first by giving an example. 3 and 4 are diagrams showing examples of document type definitions of document information. Of these, FIG. 3 is an example of a document type definition for a paper, which is a type of document. There are various formats for papers, which cannot be defined by a single document type definition. However, as long as they are summarized as a paper, they also have common characteristics.
FIG. 3 shows an example of document type definitions for two types of papers, paper A and paper B. Figure 3 (a)
Shows the document type definition for the article A, and FIG. 3B shows the document type definition for the article B. Note that the entire document type definition has a large scale, and a part of it is shown here.

The document type definition 31 relating to the article A in FIG. 3A will be described. The document type definition consists of several definition sentences. In the document type definition 31, A.
1), A. 2), A. 3) and the like are examples of definition sentences. It is considered that the units enclosed in <> are the constituent units of this document. That is, <title> refers to a constituent unit named title. Since it's cumbersome to say that a title is a constituent unit, we will use the <title> symbol in the explanation. Definition sentence A. 1) is
A document called thesis A (its highest building unit is <thesis A>
Indicates that the following types of constitutional units appear in that order. That is, <Paper A> is a series of <Title>, <Author>, <Summary>, <Begin>, <Body>, <End>, and <Reference>.

In ordinary language, the format of article A is that it has a title first, then an author,
This is equivalent to the rule of writing such that after the summary comes, the text is written after the item at the beginning, the item at the end is placed, and the reference is written at the end. Definition sentence A. The description of 1) is a method of showing such a rule more simply. Note that this description method is basically the same as the method conventionally used as a description method of the grammar of a programming language.

Definition sentence A. 2) is the definition sentence A. It defines the <text> used in 1). That is, <text> is
<Chapter> *. Here, * represents one or more occurrences of the immediately preceding description. That is, in the <text>, one or more <chapter> appears repeatedly. The document type definition is
In this way, each structural unit is defined, and the structural unit used for the definition is further defined. However, the definition sentence A. 3) The details of the definition of the paper A which follows are omitted because they are not necessary for understanding the present invention and are omitted in FIG.

Next, the document type definition 32 regarding the article B in FIG. 3B will be described. Definition sentence B. As for 1), is <Paper B> a <Title>, an <Author>, an <Introduction>, a <Text>, a <Conclusion>, an <Acknowledgement>? , And <references>. <Acknowledgement> here? Means that you may or may not have an <acknowledgement>. Definition sentence B.
2) shows that, like the case of the paper A, the <text> is the <chapter> *. Definition sentence B. 3) The details of the definition of thesis B, which follows, are omitted.

Of course, although not understood from this definition, it is assumed here that the definition contents of <Introduction> of the paper A and the definition contents of <Introduction> of the paper B are the same. The same applies to <End> and <Conclusion>. Here, comparing the formats of paper A and paper B, paper A has no <acknowledgement> and paper B has no <summary>. Also, <Begin> and <End> in thesis A correspond to <Introduction> and <Conclusion> in thesis B respectively, but both papers have different identifiers of their constituent units. It is an example.

Except for the difference in the identification name of these constituent units, the difference in the format between the two document types, Paper A and Paper B, is
Only the following points. Thesis A has a <summary> at the defined position, while there is no <acknowledgement> building block (probably, if you want to thank someone, write it at the end of <the end>), and in thesis B. Can put an <acknowledge> in the defined position (though it can be omitted), while there is no <summary>. That is, the two document types, Paper A and Paper B, define very similar document types. Then, if the definition of the document type becomes widely used due to the spread of SGML and the like, such a thing can actually occur sufficiently. If possible, it may be desirable to unify and standardize document types, but existing documents have traditionally had that format, and in reality, rather than unifying the definitions of different document types, they are similar. It is believed that features like the present invention are required to handle the relationships between the document type definitions of the.

For example, as in the case of <Introduction> and <Introduction>, the document type definition of thesis A and thesis B can be made independent even in the case where the identifiers of the constituent units are different although the contents are equivalent. It turns out that just (or already done independently in the past) is quite possible.

Further, even if a document type is newly defined, there is a demand for different identification names of constituent units that are equivalent in content. For example, you may want to use the Japanese building block name for Japanese documents and the English building block name for English documents. In children's and adult's documents, you'll want to make sure that the building block name is also a suitable identifier. When creating a document using the above-mentioned structural document function, the structural document function side displays a series of constituent unit identification names according to the document type definition of the document to be created, and the document creator is You can enter and display the contents of the composition unit, change the font size and typeface. Also in this case, it is desirable for the efficiency of document creation for the user to use the identification name of the constituent unit suitable for the type of document created by the user. As described above, it is neither possible nor desirable in practice to completely unify the document type definitions of similar document types. However, on the other hand, since they are similar documents, it is natural that some people want to treat them in common. This is achieved by associating document types.

Next, an example of another document type definition will be described with reference to FIG. 4A shows the document type definition of the article abstract C, and FIG. 4B shows the document type definition of the article journal D.
Looking at the document type definition 41 of the paper abstract C in FIG. In 1), it is shown that <abstract abstract C> is a series of <all titles> and <abstract> *. 2) shows that it is a series of <title>, <author>, and <summary>. Definition sentence C. Descriptions after the definition of <all titles> in 3) are omitted.

Although it is not understood from this definition, the <abstract> part of the article abstract C is actually a series of <title>, <author> and <summary> which are the constituent units of <thesis A> defined above. There is. Since * is added to this <abstract>, this constituent unit is repeated, and the corresponding portions of different document examples of <Paper A> are incorporated here.

<All titles> are the titles of the entire <Abstract C>. In other words, <Abstract C> is a series of <Title>, <Author>, and <Summary> of several document examples of <Paper A> repeated after the title. It shows the format of the abstracts of the articles seen.

Next, let's briefly look at the document type definition of the dissertation D in FIG. 4B. First, the definition sentence D. In 1), <Journal D> is <All titles>, <Preface> and <Article A>.
Indicates a series of *. Definition sentence D. 2) is <Paper A>, definition sentence D. 3) is <all titles>, definition sentence D.
4) gives the definitions of <Introduction>, but the definition contents and the subsequent definition contents are omitted.

In fact, this <Journal D> is preceded by several document examples of <Article A>, and <All titles>.
And <Introduction> are added to simplify the format of a typical academic journal. It should be noted that the constituent unit of document type <Paper abstract C> in FIG. 4A includes a constituent unit of another document type <Paper A>, and the document type <Paper abstract D> in FIG. 4B. > Unit includes all the unit units of another document type <Article A>, which are different from each other in the relation between the document types targeted by the present invention, which is mentioned after the description of FIG. Is an example of.

Returning to FIG. 1, the associating process between document type definitions starting from process 111 will be described. Process 11
Reference numeral 1 is a process in which the user designates the identification names of the document type definitions of the conversion source / conversion destination, which the user wants to specify in association with the keyboard 21, and the program receives them. After that, the process proceeds to the process 112, and the display device 22
The conversion source / conversion destination document type definition specified above is displayed on the screen.

An example of this screen display will be described with reference to FIG. 5A shows that in process 111, the user has designated the paper A as the conversion source document type and the paper B as the conversion destination document type, whereas the document type displayed on the display device 22 by the process 112. It is an example of an association operation screen (referred to as an association screen). The contents 510 of this association screen are the contents 520 of the conversion source document type definition 131 and the contents 5 of the conversion destination document type definition 132 extracted from the external storage device 25 by the identification name specified by the user.
It consists of 30 and. The displayed contents show the contents of the first definition sentence of the document type definition of the paper A and the paper B shown in (a) and (b) of FIG. 3, respectively. However, [] is displayed in front of each structural unit, and each structural unit is displayed in a different line. FIG. 5B is an example of the association screen displayed by the process 112 when the process 111 specifies the paper A as the conversion source document type and the paper abstract C as the conversion destination document type. Of the contents 550, the contents 560 on the left side represent the conversion source document type definition, and the contents 570 on the right side represent the conversion destination document type definition.

In the process flow process 112 of FIG. 1, after the above-mentioned association screen is displayed, the process is the next process 11.
Move to 3. In the process 113, the user designates the correspondence between the document type definitions in the front of the constituent unit [], which is the input area of the correspondence screen, and the program receives it. This is referred to as the processing of the association operation.

An example of the association designation by the user and its meaning will be described with reference to FIG. FIG. 6A shows the content 610 of the association designation designated by the user on the association screen of FIG. This content is indicated by a symbol (in this case, a, b, c, etc.) indicating the correspondence between the contents of [] corresponding to each component of the left and right document type definitions in FIG. It depends on the character). This associating method is for associating those having the same symbols attached to the constituent elements of the conversion source / conversion destination document type definition.

For example, in FIG. 6 (a), [a] is attached to both of the constituent element <title> of the paper A which is the conversion source document and the constituent element <title> of the paper B which is the conversion destination document. Therefore, these correspond. Note that the identifiers of both components have no meaning for this correspondence. In other words, it does not mean that they correspond because they have the same identification name, and do not correspond because they have different identification names. All are specified by the user here.

In FIG. 6A, the correspondences of <author>, <text>, and <reference>, which are the constituent elements of each document, are designated similarly to <title>. Furthermore, both the constituent elements of the paper A, which is the conversion source document <Introduction>, and the constituent elements of the paper B, which is the conversion destination document <Introduction>, are both [c].
Since these are attached, these correspond. The same applies to <End> and <Conclusion>. That is, the similarities between the forms of the paper A and the paper B described above with reference to the explanation of FIG. The differences are that the latter does not include the <summary> that the former includes, conversely, the former does not include the <acknowledgement> that the latter can include, and the identifiers of the former constituent units <Initial> and <End> On the other hand, the latter uses the distinguished names <Introduction> and <Conclusion>, respectively. The designation of the user in (a) of FIG. 6 indicates this correspondence. It should also be noted that such a designation makes it clear for the first time that both document types have such a relationship.

FIG. 6B shows the content 6 of the association designation designated by the user with respect to the association screen of FIG. 5B.
50 is shown. The display content of the conversion source document type definition portion 660 of the content 650 is the same as that of (a). The display content of the conversion destination document type definition portion 670 is slightly different from the corresponding portion of the association screen of FIG. That is,
The content of the definition sentence for <Abstract> is further added to the screen. This is because, for example, the user inputs the <abstract> portion on the association screen of FIG.
It is displayed in response to a request to output the definition information while instructing. FIG. 6B
Is the content 65 of the association designation specified by the user after this.
0 is shown. The designation method is as described above. As for the designation contents, <Title>, <Author>, and <Summary>, which are constituent units of <Article A> of the conversion source document type, are constituent units of <Article Abstract C> of the conversion destination document type, respectively. It shows that it corresponds to <Title>, <Author>, and <Summary>, which are the constituent units of <Abstract>.

That is, as described above, <Abstract C>
After the title, the series of <Title>, <Author>, and <Summary> of some document examples of <Article A> are repeatedly arranged. To reiterate, FIG. 6B
This correspondence will become clear only when the user specifies. Although not shown in the figure, the specification of the relationship that <thesis journal D> in FIG. 4 repeatedly includes the entire <thesis A> after <the entire title> and <preface> which are its own constituent units It is possible as well.

Returning to the explanation of the processing flow of FIG. 1, processing 1
In 13, the correspondence designation between the document type definitions as described above is made, and when the program receives this designation, the process proceeds to the next process 114. In the process 114, the contents specified by the user are stored in the external storage device 25 in the form of being extracted by the pair of identification names of both document types. After that, the process returns to the process 101 again to wait for the designation of the user's request. This time, it is assumed that the user's request is designated as the structural conversion of the document content and the control is transferred from the process 102 to the process 121.

The process of converting the structure of the document contents starting from the process 121 of FIG. 1 will be described below.

First, in process 121, the user is the conversion source /
Receives specifying the distinguished name of the target document example and the target document type. After that, the process 122 is performed.
The specified conversion source document example 134, conversion destination document example 135, and document type correspondence information 133 are read from the external storage device 25. At this time, if there is no designated conversion destination document example, it is regarded as a new document example, and a document example having an empty content is created. If the specified conversion destination document example 135 exists, it is read.

The document type correspondence information 133 is the external storage device 25 based on the pair of the conversion source document type and the specified conversion destination document type which can be understood from the specified conversion source document example.
Can be read from.

After that, the process proceeds to the processing 123, and the contents of the conversion source document example 134 are extracted for each structural unit according to the place indicated by the document type correspondence information 133, and the conversion destination document example 13 is extracted.
5, the structure is converted as the contents of the corresponding structural unit, and processing 1
Proceed to 24.

The process 124 is a known structural document editing function. Here, the conversion destination document type definition is used as the document type definition of the document to be created, and the conversion destination document example 135 read in the process 122 (or the above-mentioned document type definition). It is assumed that the new document example) is the example of the document being created, and the content of the constituent unit of the conversion destination document type created in the process 123 is treated as the content of the part of the document example being created. The well-known structural document editing function can receive the document type definition of the creation target and the contents of each of the constituent units of the creation target document example with such an interface, and create the document example. After the content of one constituent unit is created, the process proceeds to step 125, and it is determined whether or not the content of the conversion source document example 134 is exhausted.

Here, YES for "End?" Means that the contents of the conversion source document example 134 have disappeared, and N for "End?".
O indicates that the contents of the conversion source document example 134 still remain. Therefore, in the case of NO in the process 125, the process returns to the process 123 to continue the conversion process of the remaining contents of the conversion source document example 134. If YES in process 125, the process returns to process 101 to receive the next request from the user.

The processing method of the document information structure conversion method of the present invention has been described above. This can be summarized as follows in comparison with the object of the present invention.

That is, it is shown in the processes 111 to 114 that the first object of the present invention is to provide a method for the user to specify the correspondence between the conversion source document type definition and the conversion destination document type definition. It was 1: 1 correspondence between the constituent unit of the conversion source document type definition and the constituent unit of the conversion destination document type definition, a part of the constituent unit of the conversion source document type definition and the conversion destination document type definition The 1: 1 correspondence relationship between all or some of the constituent units included in the constituent unit, the appearance order of the constituent units included in the conversion source document type definition, and the corresponding configuration of the constituent unit of the conversion destination document type definition It is also shown with examples that various correspondence relationships can be realized, including correspondence relationships in which the order of appearance of units is different.

Next, in processing 121 to processing 125, the second object of the present invention, which is the second object of the present invention, is that the user specifies the conversion source document example and the conversion destination document type. It is possible to provide means for making reference and creating an example of the conversion destination document, and also for providing means for passing the contents of the constituent units of the created conversion destination document to the structural document editing function.

It is expected that the definition, storage, exchange, and use of the definition of the logical structure such as the document type definition of the SGML document and the document example according to the definition will spread in the future. Where,
Many types of document type definitions and many document examples are created for each document type definition. That is, they are completely equivalent in structure, document types in which the names of structural units are different, document types in which only the appearance order of constituent units is different, document types that include constituent units of other document types as constituent units, and There may be a document type or the like that includes a repeating unit of a document type as a constituent unit. Then, regarding the document examples according to those document types, the processing between the document examples using these relationships is meaningful. That is, changing a paper created for one academic society to a paper for another academic society, creating a summary that extracts only the title, author name, and abstract of a paper in a certain journal, and collecting papers from a certain academic society. Forming a single journal by adding sentences in different formats at the beginning and at the end, creating a collection of abstracts that extract only the titles, author names, and abstracts of multiple articles in a journal Is a request. It can be said that these requests are collectively requests for structural conversion of document information between document examples.

[0054]

According to the present invention, by utilizing the document type definition according to the conversion source document example and the document type definition according to the conversion destination document example, between the conversion source document type definition and the conversion destination document type definition, By providing a method for the user to specify the correspondence, and by converting the actually given source document example according to the user specified correspondence in this way and creating a destination document example. , This requirement can be fulfilled. Furthermore, by passing the document contents converted in this way to a known structure document editing function, the document at the conversion destination can be further arbitrarily edited, printed, or allocated.
