Embodiment Construction

[0033] figure 1 A schematic flowchart of Embodiment 1 of the method for presenting an ontology by an application modeling tool of the present invention. The present invention provides a method for presenting an ontology using a modeling tool, which can be executed by any device that executes an ontology presenting an application modeling tool, and the device can be implemented by software and / or hardware. Such as figure 1 As shown, the method of the present embodiment includes:

[0034] Step 101: Create a first layer ontology by using a modeling tool, and display it on a graphical interface.

[0035] Specifically, the first-level ontology includes first-level ontology class elements and first-level ontology relationship elements. Each ontology class element and each ontology relation element can be set on the graphical interface by dragging and dropping from the element library in the modeling tool. The names of each ontology class element and each ontology relationship el...

Abstract

The invention provides a method and a device for showing ontology by utilizing a modeling tool. The method for showing the ontology by utilizing the modeling tool includes that the modeling tool is utilized to establish a first layer of ontology and the first layer of ontology is showed on a graphical interface; the first layer of ontology comprises a first layer of ontological class elements and a first layer of ontological relative elements; a second layer of ontology is established and replaces the first layer of ontology to be showed on the graphical interface; the second layer of ontology comprises a second layer of ontological class elements and a second layer of ontological relative elements, the first layer of ontological class elements are upper layer concepts of the second layer of ontological class elements, and the second layer of ontological relative elements are upper layer concepts of the first layer of ontological relative elements. According to the method and the device for showing the ontology by utilizing the modeling tool, each layer of ontology is established in a multilayer modeling mode, a user can visually view hierarchical structures of the otology concept, the upper concepts and relationships between concepts generate constraints on lower layer concepts and relationships between lower layer concepts, and conflict generation possibilities during ontology establishment are reduced.

Description

technical field [0001] The present invention relates to computer technology, in particular to a method and device for presenting ontology by using a modeling tool. Background technique [0002] Ontology is a branch of philosophy that deals with the nature of existence. In computer and related fields, ontology refers to the basic method of applying ontology. Through conceptual analysis and modeling, objects in the real world are abstracted into concepts, and the relationship between objects is abstracted into the theory and method of the relationship between concepts. [0003] The core of ontology modeling is to clarify the concepts in the domain, the attributes and constraints of concepts, and the hierarchical relationship between concepts. There is a hierarchical relationship between objects in the real world, and there is also a hierarchical relationship between concepts in the ontology. For example, human is a kind of mammal, and mammal is a kind of animal. In the ontol...
