Spatial Knowledge Representation Model Of Simulation Scenario Based On Ontology, Zhu Jie, Hongjun Zhang
Spatial Knowledge Representation Model Of Simulation Scenario Based On Ontology, Zhu Jie, Hongjun Zhang
Journal of System Simulation
Abstract: Military simulation scenario has abundant spatial knowledge and is closely related to various models of combat simulation. In view of the lack of uniform specification for the description of simulation scenario knowledge, it is necessary to construct a spatial knowledge representation model in line with spatial thinking to effectively analyze the spatial entities and their interrelationships in simulation scenario. The ontology method is used to establish spatial knowledge domain ontology and form the formal description specification of spatial knowledge concept; the spatial knowledge structure is described hierarchically by using the method of concept knowledge tree, clarifying the semantic logic …

Application Of Domain Knowledge Representation In Simulation Tutoring For Weapon Utilization, Zhang Chi, Danhua Peng, Kedi Huang
Journal of System Simulation
Abstract: According to the requirements and characteristics of the simulation tutoring system for weapon utilization, a knowledge base depending on the domain ontology was designed. The knowledge for weapon utilization, the knowledge representation, and the method of knowledge representation were introduced. Through a combination of the ontology technology and various existing models, the key points of using specific weapon could be mastered by processing the date, information, and experience from expert. The conceptual model of knowledge was built. A knowledge base for weapon utilization was designed and implemented. The structure and function of the simulation tutoring system and rule-based expert …

Scalable Semantic Web Services Architecture Design And Service Discovery, Xiaoxing Niu, Zhixue Wang, Minggang Yu
Journal of System Simulation
Abstract: With the rapid development of computer and network technologies, the variety and quantity of Web Services on the network is also increasing. How to find the requiring services quickly and accurately becomes increasingly important. In order to solve the problems with traditional Web Services architecture, such as poor scalability and lacking of semantic information, a scalable semantic Web Services architecture was proposed, the architecture could meet the requirements to construct distributed and large-scale systems based on SOA for modern enterprises. Service publication and deletion algorithms of the architecture were studied, and dynamic adjustment algorithms of the architecture was studied …
Research On Context-Aware Model Of Combat Processes, Qiaoyu Deng, He Ming, Zhixue Wang, Zhongwei Wang
Research On Context-Aware Model Of Combat Processes, Qiaoyu Deng, He Ming, Zhixue Wang, Zhongwei Wang
Journal of System Simulation
Abstract: In traditional joint operations, all collaborators make collaboration rules in advance to guide the operations. The unknown battlefield environment varies constantly, and military organizations must make adjustments to guarantee the combat operations order. A model of operational processes based on context awareness is built. The ontology theory is introduced to present the context. On the basis of event calculus, the analysis is carried out to the perceived context of combat processes, and the variation of organizations ability and the situation of processes are provided to guide the self-synchronizing decision-making.
Ontology Based Devs Modeling Method, Rong Gang, Xiao Jun, Yunping Hu, Yiping Feng
Ontology Based Devs Modeling Method, Rong Gang, Xiao Jun, Yunping Hu, Yiping Feng
Journal of System Simulation
Abstract: In the field of modeling and simulation, it’s difficult to reuse the models because the models and simulation system are coupled seriously. The Ontology-driven modeling theory is a simulation modeling methodology for model reuse. A new DEVS modeling method was proposed based on this theory. The DEVS modeling ontology DEVSMO was built and the DEVS model could be described as the instance of the DEVSMO. This form of DEVS model was independent of the DEVS simulation environment, which improved the model reusability. A tool was developed to translate the DEVSMO instance to DEVS executable models to verify the …
Semantic Knowledge Base Constructed From Chinese Online Encyclopedia, Liu Jian, Hongbo Xu, Huifeng Tang, Yantao Jia, Xueqi Cheng
Semantic Knowledge Base Constructed From Chinese Online Encyclopedia, Liu Jian, Hongbo Xu, Huifeng Tang, Yantao Jia, Xueqi Cheng
Journal of System Simulation
Abstract: The traditional construction methods about semantic knowledge base cost a lot of manpower and material resources. In addition, knowledge is difficult to acquire timely updates. In view of the deficiency, a new semantic representation model was put forward based on semantic ontology and hypergraph theory which was named dynamic knowledge network. Then, this model was described in detail, which included theoretical basis and model elements. Under the guidance of the model, the extraction methods and storage structure were studied about semantic knowledge. A Chinese semantic knowledge base was semi-automatic constructed using Chinese 360 Encyclopedia data which could efficiently provide …

Research On Ontology-Meta Modeling Method For Equipments Sos (System Of System) Combat Simulation, Zhang Shen, Haohua Xu, Jingye Wang
Journal of System Simulation
Abstract: Aiming at the strict standard and difficulties of equipments SOS combat simulation modeling, an ontology-meta modeling method was put forward. Based on the analysis of equipments SOS combat, the basic notional units were abstracted: function unit, combat organize, combat maneuver, combat event, and combat environment, and the units mapping into UOPEE (unit, organization, proceeding, event and environment) which was a maturity and combined models collect, then constituted the descriptive UOPEE architecture with the UML method, obtaining the cyber-model architecture based on component designing and realizing method. This method makes the equipments SOS combat model easy to mapping and integration …

Business Process Modeling Algorithm Based On Ontology Language, Huang Ying, Kangshun Li, Li Wei, Keqing He
Journal of System Simulation
Abstract: In the view of problem in lack of information sharing mechanisms at the semantic level among processes, a business process modeling algorithm based on ontology language using concept hierarchy as background knowledge was proposed. The business process modeling by traditional business process languages can be transferred to ontology language (OWL) description so as to realize the semantic sharing of business process. The approach has two main advantages compared with traditional methods: (1) accelerating the building process, minimizing the conversion cost; (2) background knowledge guides the extraction of knowledge resided in database. As a way of validating the approach, part …
