The present invention relates to an ontology-based information distribution system and method thereof. More specifically, in the next generation ontology-based information distribution system and its method, which guarantees transparency of the information being distributed and improves the information using the ontology, thereby supporting collaboration among users who use the information and ensuring only the accurate information is distributed. It is about.

Workers in the field of conventional research and development spend a considerable amount of time searching on an internet portal or a publisher's homepage in order to find information necessary for themselves among numerous information resources existing on the Internet. The retrieved information file is stored in the personal computer according to the usefulness of the research and development workers.

However, despite the fact that R & D workers store a large amount of useful information resources, they often fail to use them effectively. This phenomenon is caused by the increase in the storage capacity of the personal computer, but the number of information files that can be stored in the computer has increased dramatically, but the absence of a system that can efficiently manage and search.

In particular, with the development of science and technology, collaborative research among research developers in the same field is more important than research alone, so the efficient sharing of the results of research developers' information gathering activities is urgently needed more than ever.

Currently, the information sharing system includes the operation of the electronic bulletin board by forming a web-based community among the cooperative research groups or the cooperative research system through P2P-based information sharing.However, the electronic bulletin board is a one-way information sharing system. However, due to the anonymity, many adverse functions can occur, such as accepting false information.

In addition, the current information sharing method using P2P has a disadvantage in that it does not meet the user's search intention because it merely provides a search function matching the file name or extension to the information user as well as the copyright problem.

Therefore, by adding specific semantic information to a large number of files scattered within the computer of each research and development worker, it is possible to increase the added value with valuable information and to search the document to enable users who use the file to extract the necessary information effectively and appropriately. There is a need for a system that provides functionality.

In order to solve this problem, the present invention provides an ontology utilizing system that ontotizes meta information created by a user and provides advanced information by using the same, and an information distribution system that can manage tracking and history of documents created by the user. It aims to do it.

In order to achieve the above object, the present invention is an ontology-based knowledge management server that provides information management and information distribution service, and when a document registration request signal for information management and information distribution is received from a user computer, a virus is stored in the document. Or a type validation module that checks whether the worm is included and whether the document extension is correct; An ontology storage unit for storing information about the document together with information including a URI identifier, a document structure, a concept, and additional information after meta information received from the user computer is ontology; A program storage unit for installing the ontology storage management program for verifying the meta information in association with the ontology, and then ontotizing and assigning an identifier to each ontology information; And a control module for controlling the type verification module, the ontology storage unit, and the program storage unit so that the knowledge management server performs a search, management, tracking, and distribution function of a registered document. It provides an ontology-based knowledge management server that provides information distribution services.

In order to achieve another object of the present invention, the present invention provides a registration computer for inputting document registration and meta information, combining the document and the meta information, converting the document into an ontological logical structure, and converting an identifier for identification of the document into the document. Ontology-based information in a document distribution system including a knowledge management server configured to assign and store the information stored in the knowledge management server, and a user computer for searching, inquiring and editing the document stored in the knowledge management server and re-registering the edited document in the knowledge management server. A method of managing and distributing information, comprising: (a) receiving, by the knowledge management server, the document and the meta information from the registration computer; (b) ontology and storing the received document and the meta information; (c) receiving a search request signal from the user computer; (d) inferring, visualizing and transmitting document information corresponding to the search condition received from the user computer to the user computer; And (e) transmitting a document corresponding to the download request signal received from the user computer to the user computer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a diagram illustrating a hierarchical structure of an ontology-based information distribution system and a semantic web used in the method. Referring to FIG.

The semantic web provides the ability for the computer to recognize the meaning of the information connected to the web, to search for the information the user needs, and to infer knowledge from the retrieved information. That is, the ontology-based information distribution system according to the embodiment of the present invention also includes being implemented on the semantic web.

URI 102 is a string identifying an information resource and is a unique name given to an information resource and a network path used to hyperlink the provided information resources.

XML 104 is a meta language established by the W3C. If HTML is a user-oriented style language, XML extends the usefulness of the document so that users can define and use the tags they need.

RDF 106 is designed to generate formal semantics that are lacking in XML. RDF is a framework that describes the relationships between resources on the Web and defines metadata.

RDF or RDFS can't handle the knowledge they represent because they only provide a way of vocabulary, structure, and constraints to represent Web resources. Therefore, we need an integrated data dictionary that can express and reason knowledge, and this ontology is stored in the ontology repertoire to enable reuse, sharing, learning, and reasoning.

The ontology 108 plays an important role in enabling the ontology-based information distribution system and the information registered in the method to enable knowledge sharing, reuse and processing between applications on the web.

Ontology 108 includes definitions for hierarchical classification and inference rules. Hierarchical classification defines the classes and subclasses of objects and their relationships, and inference rules are used to extract new data from known data or to filter out data that does not meet constraints.

The language that defines the schema and syntax structure for expressing the ontology is the ontology language, and ontology languages such as DAML + OIL and OWL (Web Ontology Language) are defined. Among them, DAML + OIL, proposed by W3C as a standard, is a semantic markup language for web resources, and is a frame-based ontology expression language based on W3C's RDF and RDF schema standards. Basically, ontology expressed as DAML + OIL is composed of class, property, and constraint.

2 is a structural diagram of an ontology utilization system that ontology meta information and perform inference and visualization according to a request of a document information user on an ontology according to an embodiment of the present invention.

The ontology utilization system that ontology the meta information according to an embodiment of the present invention and perform inference and visualization according to the request of the user of the document information on the ontology is provided with the ontology and meta information necessary for ontology in the process of registering the document. Provides an interface that allows input in conjunction.

Meta information may be defined as data about data (data data) (information data about data data). That is, in the embodiment of the present invention, in order to efficiently manage and search information in the computer, the meta information of the information is automatically registered or the user receives input from the user. Thus, by combining specific semantic information with a large number of files scattered in a computer, it provides a function to determine whether it is desired data without checking the contents of the data itself afterwards. For example, when writing meta information about a paper, an interface screen for inputting information including a paper title, a main author, a co-author, a published journal or journal, and a year of publication may be configured.

In this case, when the main author says "Hong Gil-Dong", the information of the same person with the same name is already registered in the knowledge management server, and it may be indistinguishable. Can be. In order to solve this problem, the ontology according to the embodiment of the present invention gives a unique identifier called URI and solves it. In other words, the names of the main authors or co-authors are provided together with information such as affiliation, age, etc. so that the person can be precisely located and given a URI. It is configured to register and give new URI.

The knowledge management server provides an interface screen for inputting meta information, and the meta information input by the user can be ontology through the process of inputting the meta information in each document to be registered by the user and receiving the URI. Store the contents in full or distributed form.

When receiving a signal for requesting the retrieval of the registered information from the user, the knowledge management server generates the information corresponding to the request information by performing inference on the ontology and provides it to the user through the visualization module. To this end, the knowledge management server provides an interface screen for document information retrieval, and performs inference on the ontology when receiving a signal requesting a search of research trends by year and subject of a specific researcher from the user through the interface screen. Thereby providing inference results to the user through a visualized output interface. Such an inference system may be implemented by using an open source library that is conventionally implemented.

3 is a block diagram illustrating an internal configuration of an ontology-based knowledge management server according to a preferred embodiment of the present invention.

As shown in FIG. 3, the knowledge management server 300 according to a preferred embodiment of the present invention includes a type verification module 302, a control module 304, an ontology storage unit 306, and a document identifier providing module 308. The document container generation module 310, the user authentication unit 312, the memory unit 314, the program storage unit 316, and the document history management module 318 may be included.

When the user registers document information in the knowledge management server, the type verification module 302 according to the preferred embodiment of the present invention performs a type check for checking whether a document contains a virus or a worm and whether the document extension is correct. Perform.

The control module 304 includes a type verification module 302, a document identifier providing module 308, a document container generating module 310, a user authentication unit 312, and a program storage unit to provide document management and distribution services to a user. 316 and document history management module 318 are controlled. To this end, the control module 304 may be configured as a microprocessor performing a function of a central processing unit (CPU). More specifically, when the document registration request signal is received from the user's computer, an interface screen for document registration is provided to the user's computer and the ontology storage management program stored in the program storage unit 316 is controlled to control the interface screen. After verifying the meta information input from the user through the ontology and verifying it, the ontology is stored and stored in the database.

In addition, the control module 304 controls the document identifier assigning module 308 to assign a unique identifier called a URI to each document registered in the knowledge management server 300. At this time, the identifier is combined with the meta information received from the user, and converted into a knowledge which is useful for search and utilization by the logical structure of the original text and the meta information of the registered document.

The control module 304 controls the document container generation module 310 to combine the registered document with an identifier, system information, etc. to produce a document container and store the document container in the ontology storage unit 306. The generated document container has a meaning that the knowledge management server 300 is a document that guarantees distribution, and the update, tracking, and verification of the corresponding document are all performed through the document container.

In addition, when the document registrant restricts the use right of the document, the control module 304 determines the use right of the document user. To this end, the control module 304 controls the user authenticator 312 to determine whether to permit the user to use the document. For example, in a case where the condition is set such that the document registrant grants the editing authority only to the members of a specific group designated in advance, and otherwise, only the reading and outputting authority is allowed, the control module 304 may provide a menu relating to the editing. Technology to display a document registered to a user in a disabled state, and to edit and store the document only after the document registrant authenticates that the document registrant is a member of a predetermined group through the user authentication unit 312. Configuration is possible.

In addition, the control module 304 controls the document history management module 318 to manage the history of the document. More specifically, the control module may support a function of allowing a person who is authorized to edit a document container created by a document registrant to edit and save a document, in which case the control module 304 may edit As soon as the document is saved under a different file name, a control command is transmitted to the document history management module 318 to combine the new file with the meta information embedded in the existing document container to create a new container. In this way, illegal disassembly or deformation of the existing document container can be prevented.

In addition, the control module 304 may support a function of allowing a document registrant to re-register an existing document container, and when receiving a document container re-registration request signal from the document registrant, the control module 304 automatically registers the existing document container. It will be decommissioned and type checked again. However, since the identifier of the initial document included in the existing document container must be maintained for managing the history of the registered document, the identifier history is left in the newly created document container by allocating a new identifier for the reregistered document.

The document history management module 318 keeps only the initial document identifier, the current document identifier, and the immediately previous document identifier for the document container to track the history, and can use the identifiers to track the entire history of the documents registered in the knowledge management server. Make sure

Since the user can check the change history of the document registered in the knowledge management server, the user can manage the version of the file, thereby enabling efficient document management and reliable distribution of the document.

In particular, in order to ensure objectivity and transparency of the distributed document, the control module 304 may not allow a user to edit meta information (identifier, system information, etc.) in the document container. It is desirable to perform the control function so that only additional information can be input.

The ontology storage unit 306 stores the document information along with the URI identifier, document structure, concept, and additional information on the ontology of the knowledge management server after the meta information is ontologyed by the control module. In addition, according to the control signal of the control module 304 serves to provide the data required to perform the reasoning and visualization according to the setting conditions requested by the user.

The user authentication unit 312 according to the preferred embodiment of the present invention performs a user authentication processing procedure of a customer under the control of the control module 304, and the memory unit 314 also processes data processed by the control module 304. Temporarily stores or temporarily stores intermediate data for linking the ontology with the meta information generated by the ontology storage management program stored in the program storage unit 316.

As described above, the program storage unit 316 verifies the meta information received from the user through the interface screen in association with the ontology, and then ontology and manages the ontology storage management program which combines and assigns identifiers to each ontology information. It is equipped. The ontology storage management program can be implemented in various ways depending on the operating system (OS) of the ontology-based information distribution system. For example, the ontology storage management program can be implemented in the 'C' programming language or the object-oriented 'C ++' and 'JAVA' programming languages.

4 is a schematic diagram showing the structure of an information distribution system according to a preferred embodiment of the present invention.

An information distribution system according to an embodiment of the present invention includes a registrant computer 402, a knowledge management server 404, and a user computer 406.

Meta information input when a user registers a document is stored ontology in the knowledge management server 404, and the knowledge management server provides a tracking, management, and editing function of the registered document.

In detail, as described with reference to FIG. 2, the meta information received from the registrant computer 402 is combined with the ontology previously built in the knowledge management server 404, and the knowledge management server 404 is combined with specific semantic information in the original text. Is registered to.

The knowledge management server 404 first performs a type check for checking whether a document contains a virus or a worm or if the document extension name is correct.

The control module of the knowledge management server 404 controls the document history management module and the document identifier assigning module for the document that has passed the type checking, thereby assigning a new identifier or an update identifier to the document. Also, the control module of the knowledge management server 404 automatically extracts or generates information such as a registration date, a creation date, a change date, a registrant, and the like for managing the history of the document from the meta information and gives the document to the document.

In addition, the control module of the knowledge management server 404 combines the information including the registered document, identifier, and system information to produce a document container and store it in the ontology storage unit.

The document container has a meaning that the information distribution system according to the embodiment of the present invention is a document that guarantees distribution. The document container is updated, tracked, and verified in the future.

When receiving a search request signal for a document registered in the knowledge management server 404 from the user computer 406, the control module provides an interface screen for the search to the user computer. In this case, since the meta information entered by the user is stored ontology, the user can search the file efficiently by inputting a search expression based on the content of the document rather than the document file name, and the control module responds to the input search expression. Infer, visualize, and display the registration document.

The user does not need to know that the document is a container, and can handle the document container similarly to a normal document. That is, when a user wants to open a document container, a decoder embedded in the container can call the corresponding application program to open the document.

The user can display, print out, or edit the document. However, this privilege range is defined by the registrant at the time of registering the document, and the knowledge management server 404 can use only the user authority of the document corresponding to the privilege range. 406. For example, if the document registrant allows only reading and outputting functions of the registered document, the menu is transferred to the user's computer with all menus related to editing disabled in the menu.

In this process, the user computer 406 may input a command to change the file name. In this case, the document container stores meta information (identifier and system information) embedded in the new file and the document container at the moment when the user saves the file name under another name. Etc.) to create a new container again. By doing so, illegal disassembly or deformation of the existing container can be prevented.

The knowledge management server 404 can provide the user computer 406 with the ability to update documents stored in the server. In addition, the user computer may re-register the updated document in the knowledge management server 404. When re-registering the document container instead of the document itself, the knowledge management server automatically dismantles the existing document container and performs a type check. .

The knowledge management server 404 controls the user computer 406 to not edit the meta information in the document container, and allows the user to enter additional information only when the registered document in the document container is updated. This process ensures an objective information distribution system of documents registered and distributed in the knowledge management server 404.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
