The article discusses the problem of knowledge representation language selection for domain ontologies. In the article the use of ontology as a tool of knowledge representation was presented and the analysis of logical formalisms such as frames, logic programs, description logic, first-order logic and common logic was carried out. Then a number of classic and markup based knowledge representation...
W niniejszym artykule opisano zdaniową reprezentację konglomeratów (semantycznych modułów ontologicznych). Pokazano, w jaki sposób reprezentacja ta może być przydatna do wnioskowania z konglomeratów. Zaprezentowano też prototypowy system o nazwie S-Pellet, realizujący działania algebry konglomeratów za pomocą reprezentacji zdaniowej. System ten wykorzystuje do wnioskowania program Pellet, realizujący...
Ontology construction is closely related to semantic networks and artificial intelligence; it has broad prospects in knowledge reuse and share, just becoming mainstream of professional knowledge base construction. This study takes ontology-based triad representation into criminology knowledge base construction. It puts forward "three bases & four layers" model of criminology knowledge...
This article introduced the concept of ontology to knowledge representation of image recognition of stored-grain pests; it focused on the use of ontology to organize and implement the ontology model, and constructed image recognition of stored-grain pests' knowledge base what could be shared by the expert system. Finally, it basically achieved system framework of the knowledge base.
The article researches on semantic knowledge base for religious portrait Thangka Images based on rules. Firstly, according to basic semantic content of religious portrait Thangka Images of Mother-Buddha and Bodhisattva etc. adopts unified and structured semantic metadata to describe domain knowledge with the aid of ontology thought. Secondly, obtains basic semantic data by establishing database, chooses...
As a conceptual model to provide semantic meaning through relationships between concepts, ontology can resolve the problems of knowledge sharing and reuse, eliminate the ambiguity of knowledge. Considering the special characters of knowledge (experiential, openness and indeterminacy) in Information Technology Service Management (ITSM) knowledge management field, a knowledge representation method based...
Classification is a famous branch of machine learning. We have tried many ways to invent and improve algorithms to get better results from given data. However, few have been done on how to revise data to adapt machine learning. In this paper, the same classifiers are implemented on same object sets which are different in the granularity of classification to show different classification can make great...
In this paper, after the introduction of ontology-based domain knowledge bases and domain knowledge representation, a formal query model of intelligent search agents that can search over distributed knowledge bases with heterogeneity for Web-based intelligent tutoring systems is proposed; and the searching process of these agents is analyzed. Ontologies are introduced to describe the semantic information...
