Web Ontology Storage / Management System and Method {SYSTEM FOR STORING / MANAGING WEB ONTOLOGY AND METHOD THEREOF}

1 is a block diagram of a web ontology storage / management system according to an embodiment of the present invention,

2 is a table structure diagram of a database system of the web ontology storage / management system of FIG.

3 is an operation control flowchart for storing / managing a web ontology according to an exemplary embodiment of the present invention.

The present invention relates to a system and method for storing and managing ontologies, and more particularly, to a web ontology (OWL: Web Ontology) which is designed to express ontology, such as a dictionary, which defines terms and relationships among terms. Language and a system and method for storing and managing the language.

Ontologies are usually a kind of dictionary that defines terms and relationships between terms, so that the computer can understand the meaning of the messages sent and received when communication is made between computers. help. When using web ontology, it is possible to find content that matches the meaning of the search when searching on the Internet, and it is also possible to automatically perform electronic commerce while communicating between computers.

However, conventionally, there is no system for storing and managing such web ontology. Instead, there is a system capable of storing RDF (Resource Description Framework), which is the parent of OWL. There is a problem in that the newly added OWL-specific features can not be saved and managed properly. That is, in OWL, for example, classes may have more meaning than they could have been expressed in RDF, such as whether they are the same concept, opposite concepts, or relationships that can be included, but they are not stored and managed. .

Accordingly, an object of the present invention is to provide a web ontology storage management system and method that enables the storage and management of the web ontology, so that the web ontology can be easily used on the Internet.

The present invention for achieving the above object is a web ontology storage / management system, a client interface for driving a module that can process a command by receiving a storage or search or extraction command from a user and processing the command and showing the results and OWL saver that receives OWL document and saves the information in OWL document to database system, OWL searcher that retrieves the information of OWL document that user wants from database system, and OWL document which is stored separately. It includes an OWL extractor for reconstructing, an OWL parser for checking the syntax and errors of OWL documents, and a database API for communicating with and communicating with the database system.

In another aspect, the present invention provides a web ontology storage / management method, comprising the steps of: (a) receiving a storage, retrieval, or extraction command from a user and inputting a user command to drive the module; Parsing and checking for grammatical or semantic errors; (c) extracting significant semantics included in the OWL document; and (d) storing the extracted semantic information in a database system. It is characterized by including.

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

1 is a block diagram of an OWL storage management system according to an exemplary embodiment of the present invention. Referring to FIG. 1, the OWL storage management system of the present invention includes an OWL storage manager for querying registry registration information and checking a result thereof, and a database system for extracting and returning corresponding information according to a query request of a client. Include.

OWL Storage Manager is a system that stores and manages web ontology. It consists of client interface, OWL storage, OWL browser, OWL extractor, OWL parser and database API.

The client interface receives the save, retrieve, or extract command from the user, runs the corresponding module that can process the command, and displays the result. The OWL store receives the OWL document and stores the information in the OWL document separately in the database system.

The OWL browser finds and displays the information of the OWL document you want from the database system. The OWL extractor reconstructs and extracts OWL information stored separately into an OWL document. The OWL parser checks the syntax and errors of the OWL document. The database API communicates with the database system and transmits and receives information.

FIG. 2 is a table diagram illustrating a table structure storing OWL information in the database system 200 of FIG. 1. As shown in FIG. 2, each table includes Triple, subPropertyOf, subClassOf, direct_subPropertyOf, direct_subClassOf, Resource, range, domain, Namespaces, Literals, instanceOf, proper_instanceOf, Class, Property, equivalentClass, equivalentProperty, sameIndividualAs, differentFrom, AllDifferent, It consists of someValuesFrom, intersectionOf, unionOf, oneOf, disjointWith, complementOf, inverseOf, and so on.

In the above, Class stores information of a class, subClassOf stores an inheritance relationship between classes, and equivalentClass stores something that has the same meaning between two classes. disjointWith stores information representing relationships that cannot be included between two classes, and inverseOf stores information representing concepts that are opposites. In this case, the various tables are distinguished and provided to store all the various meanings included in the OWL document.

3 illustrates a processing flow for OWL storage management according to an embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 and 3.

First, when a storage, retrieval, or extraction command from a user is input (S300), the OWL storage management system inputs a user command by driving an OWL retriever and an OWL extractor module to perform the retrieve or extract command (S302).

Next, the ontology storage management system parses the OWL document through the OWL parser and checks whether there is a grammatical or semantic error in the OWL document (S304). Subsequently, the OWL storage management system extracts important meanings contained in the OWL document through the OWL extractor (S306), and then controls the database interface to store the semantic information of the OWL document extracted from the OWL extractor in the database system (S308).

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the invention should be determined by the claims rather than by the described embodiments.

As described above, the present invention implements a system for storing and managing a web ontology to enable the storage and management of the web ontology that can be expressed on the Internet, thereby showing the search results intended by the user on the Internet and automating them. There is an advantage in that it is easy to use the web ontology as an essential element for the change to the semantic web environment that enables e-commerce.
