CADS: A Collaborative Adaptive Data Sharing Platform

Free registration required

Executive Summary

Content management tools like Microsoft's SharePoint allow users of an application domain to share documents and tag them in an ad-hoc way. Similarly, Google Base allows users to define attributes for their objects or choose from predefined templates. This ad-hoc or predefined annotation of the shared data incurs problems like schema explosion or inadequate data annotation, which in turn lead to poor search and analysis capabilities.
