ONTOLOGY MAPPING FOR ERP BUSINESS PROCESS VARIATIONS
Ontology represent shared knowledge about certain domain. One important feature of ontology is its ability to grow or extend to express some new business changes. In a multi tenancy architecture, like servicebased ERP (Enterprise Resource Planning) both tenant and provider have their own ontology. Tenant's small ontology must be matched or comply with provider's big ontology before transaction take place. Similarity computation for ontology will fail to address this problem, because both ontologies are different in size. Therefore, we use ontology mapping technique to measure whether tenant's ontology is comply with provider's ontology. We employ lexical and semantic similarity algorithm to do the mapping. The results indicated that this method can be used to check the compliance of tenant's ontology with provider's ontology.
