A Note on Optimal Function for Similarity Measure in Ontology Application
Wei Dong Gao, Tian Wei Xu, Li Liang, Jian Hou Gan · Advanced materials research · 2013
Ontology similarity calculation and ontology mapping are important research topics in information retrieval. One method for ontology similarity measure is using multi-dividing approach. Assume that the notation and terminology used but undefined in this paper can be found in [4] and [5]. We show that the assumption of strict ordering of xi*can be relaxed to allow some ties in the likelihood ratio. The same proof remains true if we consider equivalence classes defined by the likelihood ratio and relabel xi* as its equivalence class denoted by [xi*].
