How to install Jena on your PC, in order to visualise Ontologies?
Hello.
You can use Eclipse to run Gena.

Jena has a rich ontology and inferencing API that you can work with to build ontologies but is rarely used to visualize ontologies
- When you talk about visualization using Jena the only thing that comes to my mind about it is by using SPARQL queries to query it which can be done in the following ways:
1. Via the Jena Fuseki Server ( https://jena.apache.org/documentation/fuseki2/index.html ). This is a standalone tool that you may choose to run on your system where you could upload the ontology that you have and query it using SPARQL, a query language, for RDF/OWL. Results are returned in a table on the web browser or a raw semantic web format such as turtle, RDF/XML etc
2. You can programmatically load ontologies and use the Jena API to view the ontology ( https://jena.apache.org/documentation/ontology/ )
- If you only want to visualize ontologies that you already have, you can try popular online web tools for visualizing ontologies. My personal favorites are:
1. WebVOWL: http://vowl.visualdataweb.org/webvowl.html
2. OWLGrEd: http://owlgred.lumii.lv/online_visualization
- Protege is yet another software that has useful plugins that you can use to visualize ontologies. Its also a very popular tool to build ontology via a user-friendly GUI. A list of protege visualization plugins them maybe found here ( https://protegewiki.stanford.edu/wiki/Visualization )
