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

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

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
