The present invention relates to a rule-based electronic document conversion method and a system thereof. More specifically, the present invention relates to a technology that can apply rule-based automation techniques to the process of extracting and databaseting various types of information included in an electronic document.

Recently, with the rapid development of electronic / semiconductor field and communication technology field, the development of information society is accelerating with the spread of computers designed to process a large amount of information at high speed.

In this information society, electronic document processing systems including word processors and electronic publishing have become a reality as the necessity of electronic document processing by computers is required. However, the documents created by the electronic document processing system have various independent document structures and various forms. Because of the content information, a standard document structure model was required for the exchange and sharing of each document in a document processing environment by different document processing systems and devices.

Recently, an example of writing an electronic document using an eXtensible Markup Language (XML) has been increasing. The utilization rate of XML is increasing rapidly in the world, and the introduction of XML in the government, government offices and public institutions as well as general enterprises is increasing significantly in Korea. These electronic documents are generally written based on the grammar set by each institution.

In particular, as the number of electronic documents written in XML is rapidly increasing, there is an increasing number of electronic documents being managed by a client / server structure that maintains documents on a server and finds and provides desired electronic documents according to user requests.

As a related art known in the related art, "Application No. 10-2005-0092446 (September 30, 2005), Title of the invention: Extensible notation based electronic document versioning and a method of providing an update document using a version" is proposed. .

In the above known technology, when creating an electronic document using a grammar defining the structure of the structured electronic document, the document can be easily managed in the repository by using a modified or added date as a version value, and requesting for update information. It is a technical feature that a gradual update of an electronic document of a receiving party is provided by collecting and notifying only changes and additions using a city version value.

In addition, as a known prior art, "Application No. 10-2003-0084285 (2003.11.26), the title of the invention: XML-based electronic document conversion apparatus and method" is proposed.

Referring to the above-described known technology, the mapping unit receives a format of a target electronic document for a first type electronic document received from an external device through a management unit, and the conversion unit receives the electronic document of the first format at the request of the mapping unit. The adapter corresponding to the format converts the first IXML document.

In this case, the mapping unit generates a second IXML document corresponding to the format of the target electronic document from the first IXML document, and the conversion unit uses the adapter corresponding to the format of the target electronic document to convert the second IXML document at the request of the mapping unit. You can convert it to a document. Therefore, even if a new electronic document type is added, it can be linked with other types in a short time to increase the maintainability and adaptability of the system.

However, the above known prior arts can be used to create an electronic document using a grammar defining the structure of a structured electronic document or to efficiently perform mutual conversion between various electronic document types based on XML technology. However, there are differences in technical features from the technology of the present invention which introduces a rule-based (mapping rule) automation technique in the process of extracting and databaseting various types of information included in electronic documents (HWP, DOC). .

1 is a schematic diagram illustrating a manual input method of a word document according to the prior art.

Referring to FIG. 1, when an input document 10 such as HWP, DOC, etc. is read by a computer and provided to the user terminal 12, the user terminal 12 uses a manual input interface 12 as needed. Information is manually entered accordingly, and the manually entered data is stored in a database (DB) 14.

In this case, the user terminal 12 and the database 16 are linked with the service system 18 representing the research performance information system or the task management system.

In the prior art of the above structure, the user does not have direct access or management authority to the database for inputting data into the research performance information system or the task management system, and has not been provided a separate convenient tool for data input.

In this conventional method, since a user has to manually input data into a form by referring to an input document, he or she has to build data of an organization to which he / she belongs, which consumes a lot of manpower and time.

As a countermeasure for this, in the related art, a method of constructing and inputting data into Excel for some items has been used.

However, the preparation of electronic documents (HWP, DOC) for submission to the agency and the creation of separate electronic documents (EXCEL) also added to the burden on the system users. In addition, the efficiency of data input is reduced, and a lot of time is required for error verification of the input data.

Accordingly, the present invention is to solve the above problems, the present invention provides a rule-based electronic document conversion method and system as an alternative input method for securing the shortcomings of information construction using the existing web-based manual input interface. Its purpose is to.

In addition, according to the present invention, there is provided a word 2HML converter for converting an input electronic document into an HML document which is an intermediate XML document for processing; An HML2XML converter for applying a mapping document to the HML document to analyze information and automatically extracting information to generate an XML document for DB; And an XML2DB unit for processing the XML document and storing the data in a database. The word 2HML converter converts an input electronic document of HWP or DOC into an HML document using an HWP conversion OCX library or a DOC conversion OCX library. An HML converter comprising: an XML processing engine including an HML processor for processing an HML document and a mapping processor for generating an XML document by applying a mapping rule; HML2XML main processor for source structure processing, object structure processing, function processing, and variable processing; A file processor for processing a file and a log processor for processing a log, the XML2DB unit comprising: an XML processing engine for processing an XML document; A DB storage unit for databaseing the processed XML document; And a DB processor configured to process data to store the stored XML document in a database.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

2 is a schematic diagram showing an automatic information extraction and input method of a rule-based word document according to the present invention.

As shown in FIG. 2, an automatic rule-based information extraction system based on an input document (eg, HWP, DOC) 22 and a rule document (eg, XML) 24 according to an instruction of the user terminal 20 ( 26), the document information is converted, the necessary information is automatically extracted, and the extracted information is stored in a database (DB) 28.

At this time, the user terminal 20 and the database 28 is linked with the service system 30 representing the research performance information system or task management system.

That is, in the present invention, a database is constructed by automatically extracting information from the input electronic documents (HWP, DOC) for submission of the institution as a conventional solution. Therefore, system users can alleviate the burden by using the same electronic documents created for the submission of institutions in the system data construction.

3 is a detailed block diagram of a rule-based automatic information extraction system according to an embodiment of the present invention.

The method for automatically extracting rule-based information according to the present invention includes a first step for converting an input electronic document into an HML document which is an intermediate XML document for processing; A second step of extracting information of various forms (table, list, specific character string, etc.) by applying a mapping rule to the HML document and generating an XML document for DB processing; And a third step of storing the DB processing XML document in a database.

This process is implemented by the rule-based automatic information extraction system shown in FIG. 3, the present invention provides a word 2HML conversion engine 100 for converting an input electronic document into an HML document which is an intermediate XML document for processing; An HML2XML conversion engine 200 for analyzing the information by applying the mapping document to the HML document and automatically extracting the information to generate an XML document for the DB; And an XML2DB 300 for processing the XML document and storing the data in a database.

The word 2HML conversion engine 100 converts the input electronic document 22 of the HWP or DOC into the HML document through the HML conversion unit 110 using the HWP conversion OCX library 120 or the DOC conversion OCX library 130. .

That is, in order to convert the input electronic document into the HML document 32, an OCX library provided by each vendor is used to convert the HWP word (HWP) or the Microsoft Word (DOC) document.

In addition, in order to provide an effective conversion service for an unspecified number, a service is provided in a Windows server environment by applying a standalone daemon applying the word 2HML conversion engine 100.

The HML2XML conversion engine 200 includes an XML processing engine 210 including a HML processor 211 for processing an HML document and a mapping processor 212 for generating an XML document by applying a mapping rule; An HML2XML main processor 220 for source structure processing, object structure processing, function processing, and variable processing; A file processor 230 for processing a file and a log processor 240 for processing a log.

At this time, the HML2XML conversion engine 200 is a tool for generating XML, which is a structured document by extracting data from an HML document, which is an unstructured document, and its characteristic is to express the conversion information by a mapping document. Or a document validity verification function for checking whether a document frame has been edited, a data verification function for verifying data according to a predetermined condition, a data processing function for transforming data into a desired form, and a function for using functions and variables.

In addition, the function of the HML2XML conversion engine 200 is largely divided into a validation function and an XML document generation function. Validation does not generate an XML document. You can validate the document and data. Based on the mapping document described in advance, you can check if the wrong document has been entered, if the document's basic frame has changed, or if the wrong data has been entered.

Therefore, the HML2XML conversion engine 200 may use the mapping document 34 to analyze the HML document 32 to extract information and generate an XML document for DB storage.

In other words, the mapping (rules) document 34 in the present invention specifies various structural information about information to be extracted in the HML document 32, and includes information for verification, functions for various calculations and processing, and the like. It has a variable and contains information and rules for XML document 36 for DB storage.

Here, the mapping rule is a rule for allowing data to be accessed from an unstructured document. In the conventional unstructured documents such as hwp and doc, data access including data (tag information) is related to each other. access is not possible. In addition, there is no common rule throughout the document as in an XML document. However, even unstructured documents can apply certain rules to parts of the document, and because there is data in the document that can be used as a reference for finding other data, such data can be accessed.

In this case, the mapping document (file) includes a head, a property, a hierarchical structure and a location of data of a source document, target document information, and validation of a source document. Information, data verification information, data conversion information, and the like are classified and recorded.

The XML2DB 300 includes an XML processing engine 310 for processing an XML document; A DB storage unit 320 for databaseing the processed XML document; And a DB processor 330 for data processing to store the stored XML document in a database. The data processed file or XML document in memory form is finally stored in database 28.

That is, the extracted information has a data shape in the form of an XML document 36 in a memory or an external file for database 28 input, and is stored in the database 28 through a separate processor.

FIG. 4 illustrates an XML mapping rule document in which mapping rules are defined to extract information from an electronic document converted into an HML form among the modules shown in FIG. 3.

As shown in FIG. 4, a conversion element exists in an upper layer of the XML mapping rule document, and a head, properties, prepared, and mapping element in a lower layer of the XML mapping rule document. Are present respectively.

Looking at the functionality of each component, the head element holds information about creating and updating matching rules, and the property element contains general information about the source HML document and preference information for creating the target XML document. It is contained.

The prepared element forms the structure of the target XML document and can define the target document in advance. The mapping element links the target XML document structure with detailed mapping information for analyzing the source HML document structure. It consists of the contents for

In this case, an area located in a lower layer of the mapping restricts a range for retrieving data, and necessarily has a start point and an end point, and different areas, points, and apply. It may include.

The point serves as a reference point for finding another area or point, and the application is mainly used for generating a target document.

In addition, the area may be repeatedly and recursively performed in the area, and various functions and variables exist under the application.
