Marko Rodriguez

The document summarizes a two-year project to develop an ontology and data model to represent scholarly works and their usage. It will analyze bibliographic data and usage data from sources like journals, papers, and online usage logs to develop metrics to quantify the scholarly community. The first year will focus on developing the ontology and algorithms while the second year will analyze the results and report findings.

The Model
The Model SELECT ?x WHERE ( ?x rdf:type mesur:Publishes ) ( ?x mesur:hasAuthor lanl:marko ) ( ?x mesur:hasAuthor lanl:herbertv ) INSERT < _123 rdf:type mesur:Coauthor > INSERT < _123 mesur:hasSource lanl:marko > INSERT < _123 mesur:hasSink lanl:herbertv > INSERT < _123 mesur:hasWeight COUNT(?x) > INSERT < _456 rdf:type mesur:Coauthor > INSERT < _456 mesur:hasSource lanl:herbertv > INSERT < _456 mesur:hasSink lanl:marko > INSERT < _456 mesur:hasWeight COUNT(?x) > From the Publishes contexts, generate a weighted coauthorship network.
The Model Phase 1 is looking just at group level usage and bibliographic data
