The document discusses the Semantic Web and the Resource Description Framework (RDF). It explains that the Semantic Web aims to put data on the web in a format that machines can understand, allowing machines to process web data directly. Currently, web pages are written in HTML which machines cannot understand the meaning of. RDF provides a standard for describing resources on the web using triples of subject-predicate-object, allowing things to be described on the web in a way that machines can process. It gives an example of using RDF triples to describe a person named Amina Aiache.

2. What is Semantic Web?
• “The Semantic Web is a web of data, in some ways like a
global database” (https://www.w3.org)
• “First step is putting data on the Web in a form that machines
can naturally understand, or converting it to that form, this
creates what I call a Semantic Web : a web of data that can be
processed directly or indirectly by machines” (Tim Berners-
Lee, Weaving the web. Harper, San Fransisco. 1999)

3. The problem
• Web pages are written in HTML.
• Machines are not able to understand the meaning behind
information.
• They cannot help us find what we are interested in!

4. Solution

• RDF is A standard of the World Wide Web Consortium (W3C)
for describing resources in the Web.
• It uses triples to describe things :
o Subject – Predicate – Object
o (Thing) – (Property) – (Value)
