1 Dr Alexiei Dingli Introduction to Web Science Conclusion

2 Where would you use it? How would you use it? Do you see a need of Web Science?

3 Documented information and knowledge of organizations –lies in relational databases of specific applications, within text-based documents, web-based collaboration applications, etc. Programs typically do not freely interchange data within an organization, let alone between organizaitons Business Data Integration

4 Enterprise application integration (EAI) software –require significant customization and maintenance of common data models, and are therefore often quite expensive, troublesome, and require constant attention SW technologies looks to be an alternative method for extracting data from a wide array of applications in a usable form Business Data Integration

5 Uses advanced pattern matching techniques Associate meaning with unstructured text Used by NASA to sort huge quantities of data Case Study: Autonomy

6 Captures task information Stores it in a knowledge base A reasoning engine and agent technologies are used to interpret the knowledge Disputes reduced from 8 days to 8 hours Case Study: Celcorp (1)

7 Case Study: Celcorp (2)

19 The Semantic Web Challenge

20 apply Semantic Web techniques in order to build an online application that integrates, combines, and deduces information needed to assist users in performing tasks What is its objective?

21 Data 1.Have semantics (meaning) defined using formal methods 2.Be manipulated in such a way that new useful information is derived 3.The information processing must play a central role in the application Information sources should 1.Be derived from different sources 2.Have different ownerships 3.Contain real world data All applications must assume an open domain (information is not complete) What should a good application have?

22 –Learn about the WWW, Web 2.0 (patterns, etc), the Semantic Web (cake, etc) –Learn about knowledge management and the knowledge life cycle –Take a peak at the future –Learnt about the various XML Technologies –Learnt to develop applications using Ruby on Rails –And learnt loads of examples in the process... What did you learn from this course?
