Ontologies allow machines to understand data and process information in the semantic web. However, because of the semantic webs distributed nature, data will inevitably come from different ontologies. These ontologies may describe similar domains using different terminologies or they may have overlapping domains. Ontology mapping using mapping tools help integrate and process information among ontologies. Current mapping tools focus mainly on simple 1:1 concept mapping of ontologies. This research proposed a mapping tool that discovers complex mappings such as 1:2 concept mapping, 1:2 attribute mapping and 1:1 attribute-relation mapping. The mapping tool was evaluated using 3 existing information retrieval metrics: precision, recall and f-measure. Results were satisfactory, with the tool performing better or at par with other tools in the discovery of simple mappings and with the tool discovering complex mappings that were previously not considered in other mapping techniques.
