Projects

Open Data DEx

An interactive graph visualizer of semantic Open Data. Relationships are discovered heuristically and a graph structure created in real time, allowing users to navigate and gain insight into raw data without building formal ontologies.

Intended as a tool to explore publicly available data and reveal areas where work is needed to build semantic coherence.

Written in python and javascript. See the code on github.

tagology

A Semantic Web workbench to make datasets in any format machine-readable and publishable. Uses a BF-hypergraph ontology to convert any dataset to structured, descriptive RDF. An incidence matrix for the hypergraph then enables efficient analysis of the dataset, allowing the user to create Linked Data connections and clean up semantics and labels for formal Open Data publishing.

Intended as a tool for organizations to preserve ownership of their data while making it an authoritative, semantic, context-aware source for local AIs and autonomous machine agents.

Written in python and javascript. See the code on github.
