Embodiment Construction

[0031] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0032] First, explain the On-the-Fly technology. On-the-Fly refers to the behavior that occurs dynamically, rather than the inevitable result caused by static and predetermined behavior. It is literally translated as "real-time and instant". In fact, in the editing process of ontology files, the editing of ontology files by users is a dynamic factor, and its changes affect the final generated ontology model. Using the On-the-Fly strategy, by locating the dynamic factors in the ontology file and its scope of influence, only re-solve the scope affected by the modification. This can effectively alleviate the problem of too fast automaton file parsing resource overhead.

[0033] The present invention adopts a C / S (Client / Server, client / server) framework design based on RCP (Rich Client Platform, rich client platform), and realizes ontology model generati...

Abstract

The invention provides a device and a method for generation and management of an ontology model based on an on-the-fly strategy. The device comprises an ontology editor, a model generator, a model display, an ontology querier and the like. A user uses the ontology editor to edit an ontology file, uses the model generator to generate the ontology model in real time, uses the model display to display element relationships in the ontology model, and uses the ontology querier to query the relationships in the current ontology model. The method includes: dividing main content of the ontology model file into a static part and a dynamic part which is text information of the current ontology file at an editing position via analyzing the ontology model file; using an automat to extract static information of the current ontology file from the static part so as to generate a corresponding model; dynamically extracting and binding modified assignment at a current state position to generate a model progressively. The device and the method for generation and management of the ontology model based on the on-the-fly strategy are capable of rebuilding the model for necessary parts, so that time of model generating is reduced and system resources are saved.

Description

technical field [0001] The invention belongs to the field of ontology modeling, and relates to the construction and management of domain ontology, and specifically relates to providing an ontology model generation and management device and method based on an On-the-Fly strategy. Background technique [0002] At present, among some ontology editing tools implemented by domestic and foreign companies and research institutions, some also have the function of visual model generation. Among them, the most outstanding and widely used is the ontology editing tool developed by Stanford Medical Informatics. Model generation is not its main function. In terms of model generation, it can only clearly show the class and class hierarchical relationship in the ontology; it cannot express the role relationship in the ontology. [0003] In the field of computer science and information science, ontology refers to a "formal, clear and detailed description of a shared concept system". Ontolo...
