Ontoterminology Editor (TEDI)
Builds multilingual ontoterminologies: terminologies whose conceptual system is a formal ontology. Six of the seven published datasets were authored in it, then exported to RDF.

Semantic Tools
A suite of tools for working with structured knowledge in the social sciences and humanities, distributed openly by the TALOS AI4SSH Lab. Each tool has its own documentation; follow “Open tool” to launch the application itself.
OTV Ontology Viewer
Reads an ontoterminology as a navigable tree. Switch between the concept hierarchy alone and the hierarchy with its instances, then export a standalone copy to share.
Knowledge Graph Editor
Draws knowledge graphs by hand on a canvas: classes, individuals, typed multilingual attributes and labelled relations. Exports to RDF/XML for use anywhere else in the suite.
RDF Graph Viewer (web)
Explores RDF graphs in the browser with nothing to install. Takes Turtle, RDF/XML, JSON-LD and N-Triples, inspects metadata and namespaces, and queries the graph with SPARQL.
RDF Graph Viewer (desktop)
The Python edition, run on your own machine so your files never leave it. Extracts metadata and graph statistics, and includes a built-in SPARQL endpoint.
SPARQL Endpoint
Queries the published datasets directly in the browser, with worked example queries for each one and export to CSV, JSON and RDF. Nothing to set up.
Text Analyzer
Analyses Greek corpora: frequency, collocations and co-occurrence networks, plus LLM-backed entity recognition, tagging, sentiment and topic modelling for Ancient and Modern Greek.
Working with the suite
How the tools fit together
The tools are separate applications, but they are built around one artefact: an ontoterminology expressed in RDF. Most work in the laboratory moves through them in roughly the same order.
| 1. Author | Tedi: build the concept system and the term lists, then export RDF/OWL |
|---|---|
| 2. Inspect | OTV for the hierarchy, RDF Graph Viewer (web) or (desktop) version for the network |
| 3. Extend | Knowledge Graph Editor: add or edit entities and relations by hand |
| 4. Populate | Text Analyzer: find entities and terms in a corpus to feed back into the model |
| 5. Query | SPARQL Endpoint: ask questions of the published graph |
The data behind the tools
The endpoint, the ontology viewer and the graph viewers all read the same published datasets. Each has a page of its own describing what it models, its graph IRI, and how to cite it.
Licensing
The tools do not share a licence. Check the page for whichever you intend to use, and note that a licence covering a tool does not cover the data it operates on — the datasets carry their own terms.
| Tedi | Personal academic licence: free for teaching and research, non-commercial, not redistributable |
|---|---|
| All other tools | PolyForm Noncommercial 1.0.0 |
Citing the tools
There is no single citation for the suite. Cite the individual tool you used. Each documentation page carries its preferred form and acknowledge the funder:
This work used tools developed by the TALOS AI4SSH Laboratory,
University of Crete, funded by the European Union's Horizon Europe
programme under grant agreement No 101087269.Support
