Problems solved by technology

[0039] The limitation of the above two methods is that the generated strategy cannot guarantee that the generated data files conform to the characteristics of the real ontology file, so the data files generated by the above two methods are used as the input work for the performance analysis of the inference engine system The analysis results obta

Embodiment Construction

[0077] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0078]In this embodiment, the ontology file establishes a description expression through several OWL language constructors, and the several OWL language constructors include a class-related constructor set, an attribute-related constructor set, and a restriction-related constructor set. The set of attribute-related constructors includes the set of object attribute-related constructors and the set of data-type-related constructors. Specifically, the set of class-related constructors includes subclassof constructors, equivalentclass constructors, intersectionof constructors, unionof constructors, complementof constructors, and one of constructors; the set of attribute-related constructors includes subpropertyof constructors, transitiveproperty constructors, functionalproperty constructor, inverseof constructor, domain constructor, range constru...

Abstract

The invention discloses a method for generating a reality simulated ontology document, wherein, the ontology document establishes a description subexpression through a plurality of OWL language substructures; the plurality of OWL language substructures comprise class-related substructure sets, attribute-related substructure sets and limitation-related substructure sets. The method comprises the following steps: step 1, characteristic parameters of the ontology document required to be generated are inputted; step 2, classes are generated; step 2.1, the number of the generated classes, the number of Subclassof of the classes and the length of class expressions are determined according to the inputted characteristic parameters; step 2.2, the classes are generated by call of a recursive function f(depth)=GenerateOWLConcept(depth), wherein, depth is equal to length-1; step 3, attributes and individuals are generated according to the attribute number, the object attribute number, the data type attribute number, the sub-attribute correlation number and the individual number which are inputted. The analysis result obtained by the method is more persuasive; the analysis process is more formalized and controllable; the performance analysis of an inference machine is more comprehensive and effective.

Description

technical field [0001] The invention belongs to the technical field of performance analysis of a knowledge base system. In particular, it relates to a method for generating ontology files for simulating reality, and the generated ontology files are not only used to describe a certain field, but are used for input workflow of reasoner (Reasoner) system performance analysis. Background technique [0002] A more formal definition of ontology is to give the basic terms and relations that constitute the vocabulary of related fields, and the definition of the rules that stipulate the extension of these words formed by these terms and relations. In layman's terms, the goal of an ontology is to acquire, describe and represent knowledge in related fields, provide a common understanding of the knowledge in this field, determine the commonly recognized vocabulary in this field, and give these words and expressions from different levels of formal models. A clear definition of the relat...
