TOWARDS A CONTENT-BASED MATERIALS SCIENCE DISCOVERY NETWORK | 1 Emily C. LeBlanc

MATERIALS SCIENCE AND SOCIETY | 2

EXPEDITING THE DISCOVERY OF NEW MATERIALS Data Transparency and Integration – Scientists require access to the largest possible datasets on which to base their models Many materials science databases…and many unique formats for queries and results | 3

CONTENT-BASED MATERIALS SCIENCE DISCOVERY NETWORK Sophisticated ontological framework overlaying materials science databases A content-based networking context allows for intelligent routing of scientific content to interested parties | 4

A MATERIALS SCIENCE ONTOLOGY AND METADATA An ontology provides the metadata vocabulary for materials science content Well defined ontological structure aids in discovery of relationships among content | 5

ONTOLOGICAL STRUCTURE | 6

CONTENT-BASED NETWORKING Content is addressed by name/type (metadata) instead of location of host machines Receiver declares interest in a file type Content providers inject tagged files without knowing the destination Network is responsible for routing content | 7

CONTENT-BASED DISCOVERY NETWORK Employ the ontology in a content-based network federating materials science databases Scientists can receive relevant and up to date information about interests (materials, experiments, etc.) via queries and subscriptions | 8

COGNITIVE SYSTEM(CS) FOR MATERIALS SCIENTISTS | 10 Example: Siri A CS can process and decompose complex natural language questions CS can search vast repositories of scientific literature and experimental data
