Vitro - Integrated Ontology Editor and Semantic Web Application

Vitro is a general-purpose web-based ontology and instance editor with customizable public browsing.

With Vitro, you can:

  • Create or load ontologies in OWL format
  • Edit instances and relationships
  • Build a public web site to display your data
  • Search your data with Lucene
One of my previous blog posts talk about Protege ontology editor. One could use Protege 3.4.1 (latest release when this post is written) to create ontologies and import them to Vitro to create a powerful web portal.

Protégé-OWL editor enables users to build ontologies for the Semantic Web, in particular in the W3C's Web Ontology Language (OWL).

An OWL ontology may include descriptions of classes, properties and their instances. Given such an ontology, the OWL formal semantics specifies how to derive its logical consequences, i.e. facts not literally present in the ontology, but entailed by the semantics. These entailments may be based on a single document or multiple distributed documents that have been combined using defined OWL mechanisms

OWL has been the de-factor standard to capture the concept of knowledge base of a domain.

Apache Hadoop Core

Apache Hadoop Core is a software platform that lets one easily write and run applications that process vast amounts of data. It enables applications to work with thousands of nodes and petabytes of data in a distributed environment.

This application is based on Java (>=1.6).

Check out this new search engine from Microsoft. I am quite impressed with the map section.
