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

Existing Web

URI, HTML, HTTPStaticWWW

500 million usermore than 3 billion pages

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

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 ???

Web Metadata : Solution ?

metadata = “Data about Data” helps to impose order on chaosExamples: a library catalogue contains information

(metadata) about publications (data) a file system maintains permissions

(metadata) about files (data)

Metadata Standards ?

Adding Intelligence ?

Metadata standards make Web less chaotic but not “Smart”

Smartness : Machine performing tasks. Add Machine Interpretable Semantics over

Metadata

TCP/IP Stack

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 !!!

…(contd) Semantics

How about Ramu discovering following information

SLR <subclassof> Camera

Focal-length <equivalentProperty> size

F-stop <equivalentProperty> aperture

Big Smile on Ramu’s Face

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

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

… 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.
