Constructing Algorithm for Distributed Concept Lattice Based on Semantic Heterogeneous
Qingrong Wang · Journal of Lanzhou Jiaotong University · 2013
The difficulty of processing of heterogeneous information system is semantic heterogeneity.Based on the study of related theory and algorithm,a distributing constructing algorithm for solving the heterogeneous database concept lattice has been proposed in the paper.The variable threshold concept lattice is constructed for each subsystem with algorithm.According to mapping relationship between variable threshold concept lattice and Ontology concept lattice,the local Ontology is generated automatically or semi-automatically.Then global Ontology is produced by summarizing local Ontology.Regarding global Ontology as main concept lattice,distributing constructing of concept lattice of semantic heterogeneous database can be realized.At last,on the basis of main concept lattice which generated by current heterogeneous database,the feasibility and scientificity of algorithm are analyzed by comparing main concept lattice with the standard.
