Semantic Web?
“The Semantic Web is the extension of the
World Wide Web that enables people to
share content beyond the boundaries of
applications and websites.”
http://semanticweb.org/wiki/Main_Page
Tim Berners-Lee

"a web of data that can
be processed directly
and indirectly by machines."
Semantic Web

The vision of the Semantic Web is to extend
principles of the Web from documents to data.
Purpose
To enhance the evolution of the current Web by
enabling users to find, share, and combine
information more easily.The semantic web is a
innovative way to disseminate information by
which information can be readily interpreted
by machines, so machines can perform more of
the tedious work involved in finding,
combining, and acting upon information on the
web.
Informations are look like....

Problems with HTML
The World Wide Web is based mainly on
documents written in Hypertext Markup
Language (HTML),
Is used for coding a body of text interspersed
with multimedia objects such as images and
interactive forms.
Metadata tags provide a method by which
computers can categorise the content of web
pages.
Solution with Semantic Web
The term "Semantic Web" is depends on some
formats and technologies that promote it. The
collection, structuring and recovery of linked
data are promoted by technologies (are
specified as W3C standards) that facilitate a
formal description of concepts, terms, and
relationships within a particular knowledge
domain.
Solution with Semantic Web
These technologies include:
* Resource Description Framework (RDF),
* RDF Schema (RDFS) is a framework for vocabulary
* Simple Knowledge Organization System (SKOS)
* SPARQL, an RDF query language
* Notation3 (N3), designed with human-readability in mind
* N-Triples, a format for storing and transmitting data
* Turtle (Terse RDF Triple Language)
* Web Ontology Language (OWL), a family of knowledge
representation languages
COMMUNITY INFORMATION
SERVICES
“Services

which assist individuals and groups
with daily problem-solving and with
participation in the domestics' process. The
services concentrate on the needs of those who
do not have ready access to other sources of
assistance and on the most important problems
that people have to face problems to do with
their homes, their jobs and their rights.”
COMMUNITY INFORMATION
SERVICES
Survival Information such as that related to health, housing,
income, legal protection, economic opportunities, political
rights etc.
Citizen action information, needed for effective participation as
individual or as members of a group in the social, political,
legal and economic process.
Local information i.e., basic information concerning courses,
educational facilities, government agencies, local
organizations,fractional groups, health professionals etc.
Including a calendar of local events.

Ontology
ONTOLOGY?
The term borrowed form Philosophy. A branch of philosophy
that deals with the nature and the organisation of reality
Science of Being (Aristotle, Metaphysics, IV, 1)
Tries to answer the questions:
What characterizes being?
Eventually, what is being?
What is ONTOLOGY?

“An ontology is a formal representation of a set

of concepts within a domain and the
relationships between those concepts. It is
used to reason about the properties of that
domain.”
Why?
To share common understanding of the structure
of descriptive information
• among people
• among software agent
• between people and software

To enable reuse of domain knowledge
• to introduce standards to allow
interoperability
• to avoid repeated work

“Ontology”

covers a range of things
Controlled vocabularies – e.g. MeSH
Linguistic structures – e.g. WordNet
Hierarchies (with bells and whistles) – e.g. Gene
Ontology
• Frame representations – e.g. FMA
• Description logic formalisms – Snomed-CT,
GALEN, OWL-DL based ontologies
• Philosophically inspired e.g. Ontoclean and SUMO
ONTOLOGY

Three ‘flavours’
OWL-Lite –simple but limited
OWL-DL – complex but deliverable (real soon
now)
OWL-Full – fully expressive but serious
logical/computational problems
