1Dempster-Shafer Inconsistency Values显示文摘For several ontology constructing reasons of migration, extending or merging, the size of ontologies grows and applications become more complex, it is inevitable for us to receive an inconsistent ontology. Measuring ontology inconsistency is the basis inconsistencydealing, which can help us decide how to act on an inconsistency. Measuring ontology inconsistency with weighted formulae in numerous applications is a significant but difficult task for most efforts which only deal with the flat ontology. This paper improves inconsistency measure based on evidence theory and proposes a novel Dempster-Shafer ontology inconsistency measure method. The logical properties of these measures are studied. The properties show how to look inside the formulae and how to indicate the contribution of each formula to the overall inconsistency in the ontology set. This approach would provide us with a stronger base of inconsistency handling.LI Dongmei LIN Youfang HUANG Houkuan HAO Shudong WANG Jianxin 2014Chinese Journal of Electronics2014,23,2:0
2A Novel Text Retrieval Algorithm for Public Crisis Cases显示文摘Public crisis has the characteristics of suddenness and uncertainty,and it is necessary to combine the knowledge with the experience of other similar situations to make decisions effectively and quickly.This work combines artificial intelligent theory with information technology and brings case-based reasoning to build models consisting of the features of public crisis.We explore the case-representation approach and build a case-based retrieval algorithm.Combining the specificness of Case-based reasoning(CBR)technology in the monitoring of public crisis events,a new case retrieval algorithm for public crisis cases,named as Combined multi-similarity with set of simi-larity matching algorithm based on sememe(CMSBS),is proposed to analyze the cases with high similarity to current case.The CMSBS algorithm considers the structural and semantic similarities between two public crisis cases comprehensively.Simulation experiments are performed to validate the representation method of the knowledge,and the simulation results demonstrate that the CMSBS algorithm has superior performance in the average number of matching cases and matching accuracy rate and can work well in providing reference cases for subsequent events.PENG Yan WANG Jie JIAO Lulin 2019Chinese Journal of Electronics2019,28,4:0
