Academic Portal goals Community oriented Portal –Binding and assisting specific community –Virtual community with its Knowledge accumulation and domain specific resources Research diversification and knowledge accumulation Assistive services/tools for Researchers and Educators –building authorities in new domains –discovering knowledge/resources in European/worldwide Internet Cooperation with industry –to help research community –to provide feedback and input from research community

What do people need from Academic Portal? Information in specific research area –new and diverse areas not covered by existing classification and Subject Gateways (Virtual) Community interaction –Possibility to talk to expert (become bound into community) –to communicate with people –to find colleagues Video/audio materials –personalised experience Build personal profiles and exchange of experience and findings –Shared bookmark - to accumulate highly professional experience Access to Open Research area –Assistive tools –Automatic classification and knowledge mining

Academic Portal as Community Oriented Portal To build successful Portal you need to find/build proper community –Community membership creates willingness to cooperate in resources and services creation and development Bottom-up vs Top-down approach Possibility to communicate between people (community members) –create cooperative environment –virtual (point of) presence Finding relevant resources in diverse areas Starting with specific area and specific services in general concept Ask and propose to users –user needs driven approach
