Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structured document processing device, and more particularly to a structured document processing device capable of systematically deriving a new document type definition from an existing document type definition. .

[0002]

2. Description of the Related Art Documents are titles, creators, chapters, sections, sections,
It has a logical structure such as footnotes. For documents in which the logical structure information has been clarified by marking the start and end positions of each of the elements that make up these documents, use that information to edit, assign, co-author, and search the document. And so on.

In order to realize such document processing,
The logical structure of the document is defined in advance, and the document creator creates the document according to the definition. The definition of the logical structure of a certain document is called a document type definition, and as a means of its description, for example, ISO (International Standard)
SGML (Standardized Ge) defined by the digitization organization.
There is a general markup language).

The document type definition described using SGML is a general document type definition created by ISO, AAP (Am
erican association of pub
document type definition for books, OSF (Opera)
n Document type definitions for books, etc. These document type definitions define elements and structures that are basic and common to various documents. However, in order to represent the structures of various documents that are actually created, additional definitions are added and new document types are defined. It is necessary to create a type definition. For example, individual document type definitions will be created for document types such as reports, papers, and proposals.

By the way, the above document type definition only determines the syntax of the document, and does not specify the meaning or role of the elements of the document. The meaning is informally defined in the form of comments or commentary. In many cases, even syntactic roles such as chapters and sections are specified in the document type definition, and the meaning is identified by the content of another title element. This may be sufficient for human reading, but in consideration of computer processing, expression through such a language is not sufficient, and it is desirable to perform strict expression.

Further, when the document type definition is used for checking whether or not a prescribed item is described, there is a problem that a normal structure editor cannot perform the checking unless the semantic level is described as an element. There is.

Therefore, it is necessary to prepare different syntax elements according to the difference in meaning, that is, different document type definitions depending on the minute difference in document type. However, since there are general syntax elements such as lists and footnotes, it takes a lot of time to develop a document type definition from scratch, so it is necessary to appropriately modify and use a part of the existing document type definition. Is widely practiced.

[0008]

However, the method of appropriately modifying and using a part of the existing document type definition is difficult to deal with when the original document type definition is changed. There is a problem that it is necessary to create a new application corresponding to the document type definition of.

The present invention has been made in view of the above, and reduces the influence of the change of the basic document type definition itself and also to a new document type definition in which the basic document type definition is changed. The purpose is to enable the application created for the original document type definition.

Next, in the order of [basic document type definition holding section], [element type role specifying section], [derived document type information specifying section], [document type definition deriving section], [document conversion section] of the present invention. The configuration of the structured document processing apparatus according to the embodiment will be described in more detail and its operation will be described.

[Basic Document Type Definition Holding Unit] The basic document type definition holding unit 10 holds a document type definition (basic document type definition) that is a basis for deriving a new document type definition. Although any document type definition can be used as the basic document type definition, the document type definition normally used to represent a general document is used as the basic document type definition. In the embodiment of the present invention, the document type definition shown in FIG. 3 is used as the basic document type definition.

[Element type role designation section] Element type role designation section 1
1 specifies a role for each element type included in the basic document type definition.

Element types include: element types corresponding to chapters and sections, element types corresponding to chapter and section titles, element types corresponding to paragraphs, element types corresponding to paragraph titles, and lists (bullets). The element type corresponding to is included.

The element type role specifying unit 11 specifies element type names corresponding to predetermined roles, and holds a table as shown in FIG. This table is created corresponding to the basic document type definition held in the basic document type definition holding unit 10.

[Derived Document Type Information Designation Unit] The derived document type information designation unit 12 is information unique to an element type forming a new document type for creating a new document type definition from a basic document type definition. By specifying, the interrelationship between the element types that make up the new document type is specified. The derived document type information designating unit 12 specifically expresses the parent-child relationship between the element types forming the new document type by the amount of indentation, and holds this document type.

FIG. 7 shows an example in which the derived document type information designating section 12 designates information with respect to the element type forming a new document type. In FIG. 7, "public patent" is the main element type based on the amount of indent, and "public number" and "patent claim list" are child element types.
-It is indicated that there is a "detailed description of the invention". Also, "publication number" / "claim list" is a terminal element type that is an element type that has no child element type, and "detailed description of the invention" is "conventional technology" / "embodiment" / " It has been shown to have a further child element type of "effect of the invention".

Further, as shown in FIG. 7, a special mark "$" can be selectively added to the end element type after the element type name. As a result, terminating element types with "$" added, for example, "conventional technology" are considered to correspond to "chapter / section", while terminating element types without "$" added, such as "public number", It can be regarded as equivalent to a "paragraph".

Further, in FIG. 7, an element type whose element type name ends with "list" such as "claim list" is considered to correspond to "list".

[Document type definition deriving unit] Document type definition deriving unit 1
3 is to derive a new document type definition. There are two derived document type definitions, a direct expression document type definition and an embedded expression document type definition.

FIG. 8 shows an example of the direct expression document type definition derived from the basic document type definition shown in FIG. 3 based on the new document type shown in FIG. Direct expression document type definition
Document type definition that expresses the meaning of the element type as the name of the element type. In this direct expression document type definition, the element type name of the basic document type definition corresponding to the newly derived element type name of the document type definition is recorded as the value of the attribute "origGI".

To derive the direct expression document type definition, the basic document type definition is fetched from the basic document type definition holding unit 10, the element types are sequentially fetched from the derived document type information designation unit 12, and the element type role designation unit 11 The following process is performed while referring to the role of each element type of the specified basic document type definition.

First, a case will be described in which the element type extracted from the derived document type information specifying unit 12 has a child element type. The document type definition deriving unit 13 is a derived document type information specifying unit 1.
The chapter section element type name corresponding to the amount of indentation of the element type extracted from 2 is taken out from the element type role specifying unit 11, and the chapter section element type name is set as the value of the origGI attribute. Then, the names of the child element types are listed as the content (content model) of this element type.

For example, when the indent amount of the element type extracted from the derived document type information designating section 12 is 0, that is, in the case of the element type "public patent" in FIG. 7, it corresponds to "entire document" shown in FIG. The element type name “doc” to be extracted is extracted from the element type role designation unit 11, and “doc” is origG.
The value of the I attribute. As the content (content model) of this element type, "publication number", "claim list", and "detailed description of invention" are listed.

Further, when the amount of indentation of the element type taken out from the derived document type information specifying unit 12 is 1, that is, FIG.
In the case of the element type “Detailed description of the invention” in FIG. 6, the element type name “se” corresponding to the “first level chapter” shown in FIG.
"action" is retrieved from the element type role designation unit 11,
"section" is the value of the origGI attribute, and "conventional technology", "embodiment", and "effect of the invention" are listed as the content (content model) of this element type.

Next, a case where the element type extracted from the derived document type information specifying unit 12 has no child element type will be described. When the element type has no child element type, if the end of the element type name ends with "list", the element type name is "
There are cases where the $ "mark is attached and other cases.

First, when the end of the element type name extracted from the derived document type information designating section 12 is "list", for example, the element type "claim list" in FIG. 7, the "list" shown in FIG. The element type name "list" corresponding to "is extracted from the element type role specifying unit 11 and" list "is set to o
The value of the rigGI attribute. The content (content list) of this element type is the element type "l" of the basic document type definition in FIG.
Same as the contents of "ist". That is, "item *"
It is written.

When the element type name is marked with "$", the chapter / section element type name corresponding to the indentation amount of the element type extracted from the derived document type information specification section 12 is extracted from the element type role specification section 11, Orig the section element type name
It is the value of the GI attribute. Then, the content (content list) of this element type is made the same as the content of the element type of the basic document type definition of FIG. 3 corresponding to the chapter section element type name.

For example, in the case of the element type "conventional technology" shown in FIG. 7 with the "$" mark, since the indent amount is 2, the element type role designation unit 11 to the "second level chapter" shown in FIG. Element type name "subsectio" corresponding to
n "is taken out and" subsection "is orig
It is the value of the GI attribute. The content (content list) of this element type is the element type "subs" of the basic document type definition in FIG.
section), that is, "(ti
tle, (subsection | paragraph
h) *) ”.

In other cases, the element type name corresponding to the "paragraph" is extracted from the element type role designating section 11 and the element type name is set as the value of origGI. The content (content list) of this element type is made the same as the content of the element type of the basic document type definition of FIG. 3 corresponding to the element type name.

For example, in the case of "public number" in FIG. 7, element type name "para" corresponding to "paragraph" shown in FIG.
“Graph” is taken out from the element type role designation unit 11,
"paragraph" is the value of origGI. And the content (content list) of this element type is the same as the content of the element type "paragraph" of the basic document type definition in Fig. 3. That is, "(#PCDATA)" Write down.

FIG. 9 shows an example of the embedded representation document type definition derived by the document type definition deriving unit 13. Embedded expression document type definition is the meaning of element type
The document type definition expressed as the value of "le". The element type name of the embedded representation document type definition is the same as the basic document type definition shown in FIG.

To derive the embedded representation document type definition,
Element types are sequentially taken out from the derived document type information designating unit 12 and the following processing is performed.

First, a case will be described in which the element type extracted from the derived document type information specifying unit 12 has a child element type. The document type definition deriving unit 13 is a derived document type information specifying unit 1.
Based on the amount of indentation of the element type extracted from 2, the corresponding chapter section element type name is extracted from the element type role specification unit 11, and the element type name extracted from the derived document type information specification unit 12 is acquired by the role attribute. Add to the value you get.

For example, when the amount of indentation of the element type extracted from the derived document type information designating section 12 is 0, that is, in the case of "public patent" in FIG. 7, the element corresponding to "entire document" shown in FIG. The type name “doc” is taken out from the element type role designation unit 11, and “public patent” is added to the possible values of the role attribute.

Further, when the amount of indentation of the element type extracted from the derived document type information designating section 12 is 1, that is, FIG.
In the case of "Detailed description of the invention" in, the element type name "secti" corresponding to the "first level chapter" shown in FIG.
“On” is taken out from the element type role designation unit 11 and “detailed description of the invention” is added to the possible values of the role attribute.

Next, the case where the element type has no child element type will be described. When the element type has no child element type, the element type name ends with "list", the element type name is marked with "$", or other cases.

First, when the end of the element type name extracted from the derived document type information specifying unit 12 is "list", for example, "patent claim list" in FIG. 7, it is changed to "list" shown in FIG. The corresponding element type name “list” is taken out from the element type role specifying unit 11, and “claim list” is added to the possible values of the role attribute.

When the element type name is marked with "$", the corresponding chapter / section element type name from the element type role designation section 11 is determined based on the indent amount of the element type extracted from the derived document type information designation section 12. Is taken out, and the name of the element type taken out from the derived document type information specifying unit 12 is added to the possible values of the role attribute.

For example, in the case of "prior art" in FIG. 7 with "$" mark, since the amount of indent is 2, the element type name corresponding to "second level chapter section" shown in FIG.
"subsection" is taken out from the element type role designation unit 11, and "conventional technology" is added to the possible values of the role attribute.

In other cases, the element type name corresponding to the "paragraph" is extracted from the element type role specifying section 11 and the element type name extracted from the derived document type information specifying section 12 is roll.
e Add to the possible values of the attribute.

For example, in the case of "public number" in FIG. 7, the element type name "paragraph" corresponding to the "paragraph" shown in FIG.
Add "public number" to possible role attributes.

[Document Converting Section] The document converting section 14 mutually converts a direct phenotype document and an embedded phenotype document. Direct phenotype document (created by user with editor etc.)
10 and an example of an embedded phenotype document converted from the direct phenotype document shown in FIG.

To convert a direct phenotype document to an embedded phenotype document, the following procedure is applied to each element.

When the element has the origGI attribute, the element type name is replaced with the value and the role attribute is newly provided, and the original element type name is recorded in the role attribute value. Then, the origGI attribute is deleted. The element type is ori
If it does not have the gGI attribute, no processing is performed.

Further, the element is a chapter or paragraph element type,
And when it has a child element, a title element is generated and the title element is provided with a role attribute having a value of "generation". Put the original element type name in the content of the title element. This is necessary because in many document type definitions, the first child element of a chapter section element must often be the title element.

In order to directly convert an embedded phenotype document into a phenotype document, the following procedure is applied to each element.

When the element has the role attribute, the element type name is replaced with the value, and the origGI attribute is newly provided, and the original element type name is recorded as the value of the origGI attribute. Then, the role attribute is deleted.

The value of the role attribute of the element is "generate".
, Then delete the entire element.

If the element type does not have the role attribute, no processing is performed.

[0063]

As described above, according to the structured document processing apparatus (Claim 1) of the present invention, the element type of the corresponding document type definition is determined from the document type name, which is intuitive. It is easy to understand and can describe concise document type definition. Since the user does not need to describe the document type definition,
Designing and maintaining a new document type definition becomes easy.

Further, according to the structured document processing apparatus (Claim 2) of the present invention, the element of the corresponding document type definition is determined only by adding the indent to the document type name. Easy and concise description of document type definition is possible. Therefore, it becomes easy to design and maintain a new document type definition.

Further, according to the structured document processing apparatus (Claim 3) of the present invention, the element of the corresponding document type definition is determined only by selectively adding the display to the document type name, which is intuitive. It is easy to understand and can describe concise document type definition. Therefore, it becomes easy to design and maintain a new document type definition.

According to the structured document processing device of the present invention (claim 4), the direct phenotype document in which the meaning of the element is explicitly expressed as the name of the element type and the meaning of the element is hidden as the attribute. Since both of the expressed embedded phenotype documents can be created, a convenient document can be selected and used according to the characteristics of the application.

Further, according to the structured document processing apparatus (Claim 5) of the present invention, when a direct phenotype document is converted into an embedded phenotype document, it does not exist in the direct expression document type definition and is embedded. Since it has been decided to automatically generate the element of the element type that is mandatory in the expression document type definition, it is possible to prevent the occurrence of an error. Further, when the embedded phenotype document is directly converted to the phenotype document, the automatically generated element is automatically deleted, so that the same error can be prevented.

Further, according to the structured document processing apparatus of the present invention (claim 6), the information expressed as the attribute value in the direct phenotype document is expressed as the element type name in the embedded phenotype document. Therefore, the information can be explicitly displayed by an application such as an editor or a browser, and the degree of recognition can be increased.
