What's the Excitement about Semantic Web? • Some say Semantic Web will be bigger than WWW. • Some consider it to be the next generation of the Web. • So what is all the excitement about? • What Wh iis S Semantic i W Web? b? • Will semantics change g the Web forever? • Why and how? • What are the underpinnings of Semantic Technology?

The first Generation of the Web: the Syntactic y Web

Instructor: Amna Basharat Haider
Semantic Web Technologies
i.e. the Syntactic Web is… • A place where ▫ computers do the presentation (easy) and ▫ people do the linking and interpreting (hard).
• Why y not get g computers p to do more of the hard work?
[Goble 03] FAST-NU, Islamabad Spring 2009 - Lecture 1
Instructor: Amna Basharat Haider
Semantic Web Technologies
The first Generation of Web • Most of the first Generation of Web content is suitable for human consumption ▫ even Web content that is generated automatically from databases is usually presented without the original structural information found in databases
• Typical Web uses demand that people ▫ seek and make use of information, search for and get in touch with other people, review catalogues of online stores and order p products by y filling g out forms

Semantic Web Technologies
Keyword-Based Keyword Based Search Engines • Most Web activities (even as of now) are not particularly well supported by software tools ▫ Except for keyword-based search engines (e.g. Google, AltaVista, Yahoo)
• The Web would not have been the huge success it was, were it not for search engines
FAST-NU, Islamabad Spring 2009 - Lecture 1
Instructor: Amna Basharat Haider
Semantic Web Technologies
Problems of Keyword-Based Search Engines High recall, low precision. Low or no recall Results are highly sensitive to vocabulary Results are single Web pages Human involvement is necessary to interpret and combine results ▫ Results of Web searches are not readily accessible by other software tools ▫ ▫ ▫ ▫ ▫

The Key Problem of First Generation Web • The meaning of Web content is not machineaccessible: lack of semantics • It is simply difficult to distinguish the meaning between these two sentences: I am a p professor f off computer p science. I am a professor of computer science, you may think. Well, . . .

Hard Work using the Syntactic Web… • Complex queries involving background knowledge – Find information about “animals animals that use sonar but are not either bats, dolphins or whales”
• Locating information in data repositories – T Travell enquiries i i – Prices of goods and services – Results of human genome experiments
• Delegating complex tasks to web “agents” – Book me a holiday next weekend somewhere warm, not too far away, away and where they speak French or English Almost impossible for machines and too hard for people without automation

Approach: Semantic Web “The Semantic Web is a vision: the idea of having data on the Web defined and linked in a way that it can be used by machines not just for display purposes, b t for but f automation, t ti i t integration ti and d reuse of data across various applications” http://www.w3.org/sw/ Vision of Tim Berners Lee ! The h Semantic Web b is an initiative with h the h goall off extending d the h current Web and facilitating Web automation, universally accessible web resources, and the 'Web of Trust', providing a universally accessible platform that allows data to be shared and processed by automated tools as well as by people.

COURSE EXECUTION DYNAMICS
Semantic Web Technologies
Course Aim and Themes • The aim of this module is: ▫ To develop a critical and practical understanding of concepts, standards and f frameworks k supporting ti systems t iintegration t ti with semantics in mind x The focus is primarily on the Semantic Web. x Standards of conceptual and technological “tools” for supporting and realising semantic integration play a significant part.
FAST-NU, Islamabad Spring 2009 - Lecture 1
Instructor: Amna Basharat Haider
Semantic Web Technologies
Course Themes • Teaching, learning and assessment of the module will support these aims by providing: ▫ Practical experience of the development and use of Semantic Integration Frameworks ▫ Reflection on conceptual foundations and implications of the models and implementations ▫ An awareness of the conceptual and technological choices available when developing Semantic Web applications x ontologies, web services, inferencing mechanisms, etc.
▫ Experience and exposure to Semantic Web languages, such as XML, RDF and OWL. x The course, however, does not attempt to cover the languages comprehensively
FAST-NU, Islamabad Spring 2009 - Lecture 1
Instructor: Amna Basharat Haider
Semantic Web Technologies
Course Learning Outcomes • The learning outcomes for the module are to: ▫ Describe and discuss the concepts surrounding the semantic integration of data/information alongside supporting technology frameworks ▫ Demonstrate an awareness of the core standards that provide a foundation for semantic integration frameworks ▫ Use appropriate skills/abilities to practically explore the state-of-the-art approaches to semantic integration in p practice ▫ Reflect critically on the use of semantic frameworks in the g sphere p wider organisational
