New Science Paradigms

• Thousand years ago: Experimental Science

- description of natural phenomena• Last few hundred years:

Theoretical Science - Newton’s Laws, Maxwell’s Equations …

• Last few decades: Computational Science

- simulation of complex phenomena• Today:

e-Science or Data-centric Science - unify theory, experiment, and simulation - using data exploration and data mining– Data captured by instruments – Data generated by simulations– Processed by software– Scientist analyzes databases/files(Credit to Jim Gray)

What is a scientific Collaboration ?

• Definition• Two or more people work together to create or achieve the same

thing. • Key points

• Different or same discipline scientists• Form a Virtual Team• Need a agreement• Have a common research theme• Divide task into several works• Discuss problems, use instruments and share information• Goal: create new knowledge

9

Collaboration Technologies

• Access to• People

• Instruments

• Stored information

• Synchronous vs asynchronous• Chat, video conferencing, audio streaming

• Shared objects of conversation (like data)

• Threaded discussions

• Electronic notebooks

• Transitions between them

• They are limited to address users’ problems!

10

Primary services for SCC

• Virtual Team

• Access Instrument

• Sharing Data / Expertise

• Activity Management

• Online Discuss

Strategy to Create the SCC

• State of the art ---Some efforts of science communities• UK ： e-Science• EuroGrid• USA: Cyberinfrastructure---Globus Toolkits• Japan ： ITBL （ IT Based Laborarory ）• China Grid initiative

• IT and commercial product• Netmeeting Polycom WebEx• Middleware: Workplace 、 SharePoint 、 WebLogic • Platform: .NET ， J2EE• Forum and whiteboard , etc.

• Strategy: Choose the mature and simpler technology to address users’ problem.

Lessons Learned

• How to address the user’s application simpler? • System development is less and less about coding than

about using things and gluing them together.• Create a flexible enough architecture to allow for

changes.• Customers will not be able to elucidate at the start what

they want; only by using the system will they be able to tell you what you should have done. (Semantic gaps)

• SSC 1.0 rely on MS SharePoint ; SSC 2.0 open source • Individual performance assessment model and fair

agreements (win-win business model). • Future concerns should be e-community trust metrics.
