Semantic Provenance for Science Data Products - Application to Image Data Processing

Concepts:eScience & Provenance

Abstract:

A challenge in providing scientific data services to a broad user base is to also provide the metadata services and tools the user base needs to correctly interpret and trust the provided data. Provenance metadata is especially vital to establishing trust, giving the user information on the conditions under which the data originated and any processing that was applied to generate the data product provided.
In this paper, we describe our work on a federated set of data services in the area of solar coronal physics. These data services provide a particular challenge because there is decades of existing data whose provenance we will have to reconstruct, and because the quality of the final data product is highly sensitive to data capture conditions, information which is not currently propagated with the data.
We describe our use of semantic technologies for encoding provenance and domain knowledge and show how provenance and domain ontologies can be used together to satisfy complex use cases. We show our progress on provenance search and visualization tools and highlight the need for semantics in the user tools. Finally, we describe how our methods are applicable to generic data processing systems.

Description:
Science has fully entered a new mode of operation. E-science, defined as a combination of science, informatics, computer science, cyberinfrastructure and information technology is changing the way all of these disciplines do both their individual and collaborative work.
As semantic technologies have been gaining momentum in various e-Science areas (for example, W3C's new interest group for semantic web health care and life science), it is important to offer semantic-based methodologies, tools, middleware to facilitate scientific knowledge modeling, logical-based hypothesis checking, semantic data integration and application composition, integrated knowledge discovery and data analyzing for different e-Science applications.
Partially influenced by the Artificial Intelligence community, the Semantic Web researchers have largely focused on formal aspects of semantic representation languages or general-purpose semantic application development, with inadequate consideration of requirements from specific science areas. On the other hand, general science researchers are growing ever more dependent on the web, but they have no coherent agenda for exploring the emerging trends on the semantic web technologies. It urgently requires the development of a multi-disciplinary field to foster the growth and development of e-Science applications based on the semantic technologies and related knowledge-based approaches.
