Semantic Technology
How Does it Work?
Graeme Wood
Business Issues
• Billions of devices and systems
connected to internet
• They produce 5 exabytes of data per day
• This data can not be analysed effectively
• Traditional programs and data analysis
tools restrict open analysis
5 exabytes = 5,500,000,000,000 Mbytes
Semantic Computing
• Syntactic Interoperability
– Set of rules that defines correctly structured data or documents
• Semantic Interoperability
– Enables applications to understand the meaning of data
– Provide insights into the context
Original Semantic Web
• Developed by Tim Burners-Lee
• Developed through World Wide Web
Consortium (W3C)
• Uses common interoperability
standards for human to access web
– HyperText Transfer Protocol (HTTP)
– HyperText Markup Language (HTML)
– Extensible Markup Language (XML)

Semantic Web (W3C)
• Resource Description Framework (RDF)
– Makes content available to computers
– Describes all facts as 3 part descriptors = triple
– A triple consists of a subject, a predicate, and an object

Semantic Web (W3C)
• Ontology
– Describes a system of relationships
– Is a schema, a model for constructing
frameworks of information
– Is not hierarchical (no parent child
relationship)
– Can be extended or combined with
other ontologies
Semantic Web (W3C)
• Web Ontology Language (OWL)
– Is computational logic-based language
– Show the data schema and show relationships about the data
– Users can infer new facts from existing facts
Semantic Web (W3C)
• SPARQL Query Language
– Is a set of standards accessing and updating data across
various database where data in RDF format
– Can be used to transmit queries across a network
– Can reveal patterns not apparent when data stored
Benefits of Semantic Web
• Developers can model data into
RDF/OWL ontologies that can defined
relationship
• Developers can create mappings of
existing structured data sets
• Developers can utilise other AI tools to
reveal patterns not apparent when
data stored
Common Artificial Intelligent Tools
Future for Semantic Computing
• Semantic developers continue to refine W3C based tools for
specialist platform
• AI vendors develop hybrid AI platform including NLP, Machine
Learning etc
• Traditional business application vendors incorporate AI tools
within their own development to create
“Intelligent versions”

  • #2 To export video in Powerpoint 2010, Click the File tab, then Save & Send, the Create Video. Make sure Computers & HD Displays is set to 1280x720 and leave the other settings as is. Hit Create Video and you’re done. It takes a little while! Chris Webb http://compelling.tv
