Constructing domain ontology of e-business based on fuzzy rough concept lattices

Abstract

The aim of ontology is to obtain, describe and express the knowledge of related domain. The method of conceptual similarity in electronic commerce based on FRFCA is proposed by introducing of trapezoidal fuzzy number to represent the fuzzy similarity. The paper offers a methodology for building ontology for knowledge sharing and reusing based on fuzzy rough concept lattices union. A concept similarity measure method based on fuzzy rough concept lattice is proposed to enhance quality of recommendation when lacking for sort of user's interests. The experimental results indicate that this method has great promise. © 2011 Springer-Verlag Berlin Heidelberg.
