Provides access to large amounts of data, coming from various
resources from all over the world
Need to make this data available and searchable through the portal
Realization by exposing metadata
Integration of an ontology to provide the necessary controlled
vocabulary and semantics which can be explored for enhanced
information retrieval

KAON
KAON is an open-source ontology management infrastructure
Major Components:
KAON Portal: a web based portal for browsing KAON ontologies
KAON API: a programming API to access the ontology
independently from any storing mechanism
Engineering Server:
databases to provide concurrent access and scalability
Text-To-Onto: Semiautomatic ontology creation using text mining
techniques
API = Application Programming interface
