<jats:italic />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 x<jats:italic><jats:sub>i</jats:sub></jats:italic><jats:sup>*</jats:sup>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 x<jats:italic><jats:sub>i</jats:sub></jats:italic><jats:sup>* </jats:sup>as its equivalence class denoted by [x<jats:italic><jats:sub>i</jats:sub></jats:italic><jats:sup>*</jats:sup>].</jats:p>
