Geographic Object-Based Image Analysis (GEOBIA) techniques have become increasingly popular in recent years and are able to incorporate and develop ontology model within the classification process. They have been claimed to represent a paradigm shift in remote sensing interpretation. Nevertheless, it is lack of formal expression and objective modelling of the whole process of GEOBIA, and lack o...

At present, ontology, by its abundant concept semantic relations、formal share conceptualization model、unified resource description framework, is frequently applied in the expansion of query, semantic indexing of resources、the organization of search results etc. However, by using ontology and ontology-related processing technologies, carrying out an automatic semantic expansion to user query and...

This paper describes the latest version of the ABC metadata model. This model has been developed within the Harmony international digital library project to provide a common conceptual model to facilitate interoperability between metadata vocabularies from different domains. This updated ABC model is the result of collaboration with the CIMI consortium whereby earlier versions of the ABC model ...

In model-based diagnostic algorith assumed that the model is correct. If the model is incorrect, the diagnostic algorithm may diagnose the wrong fault, which can be costly and time consuming. Using past maintenance events, one should be able to make corrections to the model in order for diagnostic algorithm to correctly diagnosis faults. In this paper, a maturation approach is proposed which us...

The technical challenges associated with the development and deployment of ontologies have been subject to a considerable number of research initiatives since the beginning of the nineties. The economical aspects of these processes are, however, still poorly exploited, impeding the dissemination of ontology-driven technologies beyond the boundaries of the academic community. This paper aims at ...

ontology is a requirement engineering product and the key to knowledge discovery. it includes the terminology to describe a set of facts, assumptions, and relations with which the detailed meanings of vocabularies among communities can be determined. this is a qualitative content analysis research. this study has made use of ontology for the first time to discover the knowledge of vaccine in ir...

Ontologies facilitate the integration of heterogeneous data sources by resolving semantic heterogeneity between them. This research aims to study the possibility of generating a domain conceptual model from a given ontology with the vision to grow this generated conceptual data model into a global conceptual model integrating a number of existing data and information sources. Based on ontologic...

Ontology similarity calculation and ontology mapping are crucial research topics in information retrieval. Ontology, as a concept structure model, is widely used in biology, physics, geography and social sciences. In this paper, we present new algorithms for ontology similarity measurement and ontology mapping using harmonic analysis and diffusion regularization on hypergraph. The optimal funct...

This paper presents a Petri net based analysis of ontology for indoor location-based services. The proposed method builds up a Petri net model for the given ontology at the first step. Then, it analyzes the Petri net model by running the simulation on it. The proposed method of building a Petri net model for the given ontology is given in the paper. Then algorithms of performing inferences on t...
