On-To-Knowledge project as a typical example aimed at
developing an ontology-based tool suit that efficiently processes the large numbers
of heterogeneous, distributed, and semistructured documents. The following tools
from this project were developed:
??? OntoBuilder extracts machine-processable metadata from documents in RDF
formats. It consists of two modules, OntoExtract and OntoWraper. OntoExtract
extracts information from unstructured free text while OntoWraper does
information from structured sources.
??? Sesame stores RDF and RDFS data extracted by OntoBuilder and provides
query facilities.
??? OntoShare facilitates and encourages the sharing of information between
communities of practice.
??? OntoEdit is a graphical editing tool enabling knowledge engineers to codify
and manage an ontology.
??? QuizRDF (or RDFferret) is a search engine that combines full-text search with
an ability to exploit RDF data in searching.
??? Spectable personalizes information as a content presentation platform featuring
custom-made information presentations.
