Katexowl
stands for Kasimir Toolkit for Exploiting OWL Ontologies.
It consists in a set of tools designed to be parts of a semantic portal
dedicated to knowledge management and decision support. Katexowl has
been mainly applied for the building of a semantic portal in the
context of the kasimir project for knowledge management in oncology.
Katexowl
is made to provide elements to be included in a semantic portal.
Its central component is a knowledge server, KOWL, able to load,
manipulate and reason with OWL ontologies available on the (semantic)
Web.
Two clients of this server has been implemented, EdHibou and NavHibou,
that are distant graphical interfaces relying on KOWL to provide a
intelligent acess to the knowledge contained in OWL ontologies.
KOWL : KOWL is the knowledge
server of Katexowl. It is made
of as a set of Java classes, implementing OWL manipulation and
reasoning features and designed to be deployed as a SOAP web service.
It relies on the
Jena Semantic Web Framework for Java for OWL parsing
and manipulation, on the Pellet
OWL Reasonner for the reasoning, and on
proper cache mechanisms. You can refer to the KOWL page for
more information.
EdHibou : EdHiBou is an
intelligent instance editor/creator for OWL.
Basically, this means that, once you have selected a class of an OWL
ontology, EdHiBou
will dynamically generate an interface for building
an instance of this class. Reasoning services on OWL are used in the
initial interface generation phase and dynamically during the edition
process: for finding the properties that can be applied to the
considered class, for finding the possible values for these properties,
and for filling property values that can be inferred from the
information already given. EdHibou
is a HTTP client of the KOWL
knowledge server. You can refer to the EdHibou page for more
information.
NavHibou : NavHibou is a PHP application providing intelligent
navigation features in OWL Ontologies. It allows the user the visualize
declared or inferred knowledge elements concerning OWL classes, and to
follow links between these classes. In practice, NavHibou generates Web
(HTML) pages and is then acceded using a Web browser. NavHibou is a
SOAP client of the KOWL
knowledge server. You can refer to the NavHibou
pages for more information.
