SemTk: Semantics Toolkit
Built on the W3C
It is composed of two main parts:
- SemTk Java library - the java used to build the back-end services. It has it's own API for other uses.
SPARQLgraph is a web application that enables drag-and-drop:
- SPARQL query generation (SELECT DISTINCT)
- Execution of the queries (Supports Virtuoso. Other SPARQL 1.1 endpoints should be easy to add).
- Drag-and-drop ingestion of .csv files
The tool is designed for triple-stores with an ontology-based model. We use SADL.
It uses a modified A* path-finding algorithm to make query-generation simple.
