SESAM4A guide to semantics in the Linked Open Data cloud

Presented byRobert HP Engelsproject leader

Semi-semantic Models for Cross-Sector Portals


Project Key Facts

● project start april 2008 – ending march 2011

● focus on open standards and freeware

● results shown in different application domains

● funded by NFR with ca 30% funding

● 10 partners


Consortium Partners...


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!


..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


● 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 architecture


SESAM4's five pilars

1. Use Case: Company Information

2. Use Case: Tourism

3. WP R&D: ontology and semantic lifting

4. WP Technology: Semantic Web and ISO stacks

5. WP Best Practices: steps into the “semantic” future


some trends


Are we able to imagine where it goes?





Tourism demonstrators

● “On Board”– Fjord1, digital signage

● “What's On”– iPhone, map, events & user interests

● “Digitur”– Digital tour Bergen, POI & shared user created content

● “Place Companion”– Trip advisor, user incentives, shared user created

content, POI


What is “On board”?

Information and entertainment system for travellers with aim to give passengers a more meaningful travel

semantically lifted data sources in Sesam4

● Tellus – POI/events

● Fylkesarkivene – steder

● DBPedia – POI/personer/steder

● FourSquare – tweets/evaluations

● (/w Semicolon): BRREG

● Under construction:

– Popsenteret

– Artists

– Venues

● Wish list

– Stedsnavn/GeoLocation

– Norwegian “Public Persons”


Pillar Best Practices or “the process to introduce semantics”


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)
