A VOLCANO ERUPTS: SEMANTIC DATA REGISTRATION AND INTEGRATION

We present a progress report in a research effort (Semantically- Enabled Scientific Data Integration) into the application of semantic web methods and technologies to address the challenging problem of integrating heterogeneous volcanic and atmospheric chemical compound data in support of assessing the atmospheric effects of a volcanic eruption. The accompanying requirement for this level of data integration is a semantic registration of a variety of datasets to domain and integrative ontologies that we have re-used from other projects, adapted and evolved as part of this project and developed ourselves. We will demonstrate how ontologies are implemented by leveraging existing distributed semantic technology frameworks and how we provide this smart data integration capability in support of interdisciplinary scientific research activities.
