Meta-modelling for ontology development and knowledge exchange
نویسنده
چکیده
One of the sources of heterogeneity of ontologies is that different ontologies have different necessities of modelling. This paper presents a biphase method to deal with these different necessities. Phase I of the method models how to model the ontology, obtaining a meta-model. Such meta-model can be expressed in LBIR, a formal and declarative language that has been specifically designed for this task. To save resources, a reference meta-model that can be modified and reused is provided. During phase II of the method, the ontology is modelled following the metamodel obtained in the first phase. Furthermore, a tool (called ODE) provides software support to the method. Such tool generates SQL schemas from LBIR, and allows the modelling of the ontology following the selected meta-model. This approach eases the interoperability between groups located in different geographical locations that have to build the same ontology, since the meta-model to be used can be exchanged through LBIR.

The ATHENE modelling tool enables business people to create knowledge-intense process models without having to know the complexity of modelling ontologies. ATHENE is based on a three-level hierarchy of metameta, meta and object level. It allows business people to model business processes graphically meanwhile these processes are transformed internally into ontologies.

In this study, by using a multi-objective optimization technique, the optimal design points of forced convective heat transfer in tubular arrangements were predicted upon the size, pitch and geometric configurations of a tube bank. In this way, the main concern of the study is focused on calculating the most favorable geometric characters which may gain to a maximum heat exchange as well as a m...
