Shared and personal views on collaborative semantic tables

Abstract

The scenario defined by current Web architectures and paradigms poses challenges and opportunities to users, in particular as far as collaborative resource management is concerned. A support to face such challenges is represented by semantic annotations. However, especially in collaborative environments, disagreements can easily rise, leading to incoherent, poor and ultimately useless annotations. The possibility of keeping track of “private annotations” on shared resources represents a significative improvement for collaborative environments. In this paper, we present a model for managing “personal views” over shared resources on the Web, formally defined as structured sets of semantic annotations, enabling users to apply their individual point of view over a common perspective provided in shared workspaces. This model represents an original contribution and a significative extension with respect to our previous work, even being part of a larger project, SemT++, aimed at developing an environment supporting users in collaborative resource management on the Web.
