Outline

• Current Web
• Metadata over Web
• Semantics over Web
• Killer SW App OntoDoc
• Work and Research Outcomes
• LIVE DEMO !!

Existing Web
500 million user more than 3 billion pages
WWW
URI, HTML, HTTP
Static

Web Philosophy

• The World Wide Web is a big and impressive
  success story, both in terms
• of the amount of available information and
• the growth rate of human users
• Penetrates most areas of our daily life and
  business.
• This success is based on its simplicity
• The restrictiveness of HTTP and HTML allowed
  software developers, information providers and
  users to make easy access of the new media
  helping it to reach a critical mass

5
But

• However this simplicity may hamper the further
  development of the Web
• What we see currently is the very first
  version of the web and the next version will
  probably even more bigger and much powerful
  compared to what we have now.
• Chaos ???

6
Web Metadata Solution ?

• metadata Data about Data
• helps to impose order on chaos
• Examples
• a library catalogue contains information
  (metadata) about publications (data)
• a file system maintains permissions (metadata)
  about files (data)

7
Where Metadata fits over Web
resource
document
rights
discovery
administration
management
content
archival
rating
status
products and
process control
services
or description
database
security and
schemas
authentication
8
Claim Metadata can exist about anything

• People
• Places
• Objects
• Concepts
• Documents
• Archives
• Databases

9
Metadata Standards ?
MICI
10
Adding Intelligence ?

• Metadata standards make Web less chaotic but not
  Smart
• Smartness Machine performing tasks.
• Add Machine Interpretable Semantics over Metadata

Semantics
Metadata
WEB (HTTP, URI)
TCP/IP Stack
11
Semantics ? For e.g.
Your PDA Agent (Ramu) is Searching for a Camera
for your trip to California ! Your preferences
Camera with 75mm-300mm zoom size and aperture of
4.5-5.6 www.nikon.com has a camera with following
specifications ModelT130 SLR with focal-length
75mm-300mm and f-stop 4.5-5.6 Ramu is Confused
!!!
12
(contd) Semantics

• How about Ramu discovering following information
• SLR ltsubclassofgt Camera
• Focal-length ltequivalentPropertygt size
• F-stop ltequivalentPropertygt aperture

Big Smile on Ramus Face
13
The Semantic Web

• Serious Problems in information
• finding
• extracting
• representing
• interpreting
• and maintaining

WWW
URI, HTML, HTTP
Static
14
The Summer of 2003 !!! Goals

• Conceive a real world Semantic Web based
  application and implement it.
• Use Semantic Web technologies to solve a hard
  challenging problem.
• End of the day someone should use the application
  rather than just fill bytes on our hard disks
• Feasible within few months

15
OntoDoc A Collaborative Web portal for Life
Sciences Researchers

• Exponentially growing interdisciplinary areas in
  Life Sciences
• Need for smooth interdisciplinary collaborative
  research across organizational boundaries.
• Provide Intuitive and easy interface for
  collaborative tools on Web

16
contd OntoDoc marketing

• Smart Collaboration !!
• Use Knowledgebase on backend (rather than
  conventional Database)
• Discover and Prompt users with Connections
• Other Researchers
• Interesting Publications
• Related News
• Ubiquitous Access !!! Firewalls No Problem,
  Platform No Problem.

22
OntoDoc From here

• Issues
• Privacy
• Acceptance in community
• Information Extraction Plugin
• Implementation Challenges
• Incorporate immatured Semantic Web tools
• Platform issues
• Redland the KB available only for nix
  platforms
• Webportal .NET based Windozz

23
Assessments Lessons Learnt

• Tackling conflicting demands
• Acceptability vs Simplicity
• Practical vs Research Value
• Bridging Conceptualization and Implementation
• Working Collaboratively Lots of useful comments
  from UDIC members and Dr Lee.
• TIME is valuable !!
