OKKAM tutorial accepted at ESTC2009
The tutorial entitled "Using the Entity Name System for Managing and Interlinking Entities in Networks of Data" has been accepted at ESTC2009
European Semantic Technology Conference (ESTC2009):
Description of the OKKAM tutorial
Rationale
One of the expected benefits of semantic technologies is to enable
innovative and smarter services based on the integration of many
interlinked data sources, not only on the Web, but also (and perhaps
even more evidently) in corporate networks, where a lot of useful data
is "locked" into legacy systems and can be integrated only at the cost
of expensive ad hoc solutions.
This scenario presupposes that organizations and content providers
implement a virtuous circle of creating, sharing, interlinking, reusing
and aggregating data. In theory, current semantic technologies offer a
viable and scalable approach for implementing such a virtuous circle;
however, in practice, very little methodological and infrastructural
support has been provided to lower the costs and the entrance barriers
for interested actors.
This technical tutorial will present a new infrastucture, called Entity
Naming System (ENS), which will help organizations, companies,
data/content providers and end users to create high quality interlinked
content in a much fmore efficient and effective way, both in closed
networks (Intranets) and on the Web. In addition, several examples of
how common tools (from text processors to ontology editors) can be
extended to interact with the ENS will be illustrated. Practical
demonstrations of the immediate benefits of an ENS-empowered network
will be given.
Objectives
- Understanding the entity-centric (URI-based) approach in the creation of interlinked data
- Understanding the novelty of the ENS approach and solutions
- Getting acquainted with the APIs of the ENS
- Learning how to use and implement ENS-enabled tools
- Guidelines for using the ENS in integration with Linked Data
Program (still tentative)
- Short introduction to the principles and practices for interlinking RDF datasets [1/4h]
- Concept and implementation of the ENS (architecture, entity repository, graphical interfaces, APIs, performance) [1/2h]
- The concept and process of OKKAMization (annotation of content with OKKAM ids) and its relations with named entity recognition and information extraction [3/4h]
- Introduction and use of the following ENS-empowered tools: MS Word & OpenOffice (text processing), Protege & NeOn tooolkit (ontology editing), blogger (blogging), hotmail (webmail), foaf-o-matic (social networking), Sig.ma (semantic search) [3/4h]
- Practical session: creating Linked Data through the ENS
- Showcases and business scenarios: a news portal, a commercial community portal, a regional tax agency, an academic web site
Take-home lessons
- Entity-centric versus document centric approach to
information management
- The concept and technical description of the Entity Naming System
- How to use the suite of ENS-empowered tools developed so far
- How to develop new ENS-empowered tools
- New methodologies for creating linked data
