Project Overview
What are the challenges? ...
● Genuine interaction & communication between content
creators, owners and consumers.
● Globally Identifiable Information on Objects
● Globally Identifiable Statements about Objects and other statements
● Understanding ST's implications,
● Transforming your business and people,
● Adapting your business model!

Project Overview
..and what are the SESAM4 Objectives?
● To develop open standards and tools that will lower the barriers of entry in the
area of semantically enhanced portals and services and make it possible for small
and medium sized companies and organizations to exploit semantic systems.
● To develop methods, models and procedures for semi-automatic generation of
ontologies from unstructured text indexes for use as background variables for
semantic annotations.
● To improve, particularly in the area of scalability, current methods for text
mining and indexing.
● To develop methods, models and procedures for integrating content
management system based on RDF with content management systems based on
Topic Maps and for semantic integration and coordination of large multi lingual
content management systems
● To verify the functionality and scalability of these semi-automatically generated
ontologies to integrate multiple large scale content management systems

Project Overview
● Open Source
– It will deliver Open Source software
● Best Practices
– Based upon experiences from the community and project-
owned reference implementations
● Community involvement
– Where possible, the projects' results will be available for and
discussed with relevant communities.
...SESAM4 is an Open Project

Project Overview
Wrap up on SESAM4
● Sesam4 is:
– an Open Project
– aimed at Inter-operability through Semantic Technologies
– Supporting Linked Open Data
● What does Sesam4 for you?
– Trends, experiences and ideas in reference implementations
– Technology for you to use: stacks to get started, lifting existing data
for you & let you lift your own data (for internal use?)
– Best Practices & Guidelines for you to “semanticize your
environment” (processes, data, integration)
