Creating a PurposeNet Ontology: An insight into the issues encountered during ontology creation

PurposeNet is an ontology based on the principle that all artifacts (man-made objects) exist for a purpose and all its features and relations with other entities are giverened by its purpose. We provide instances of ontology creation for two varied domains from scratch in the PurposeNet architecture. These domains include MMTS domain and recipe domain. The methodology of creation was totally different for the two domains. MMTS domain was more computaionally oriented ontology while recipe domain required a post-processing after manually entering the data. The post-processing step uses hierarchical clustering to cluster very close actions. MMTS ontology is further used to create a simple template based QA system and the results are compared with a database system for the same domain.
