Digital Enterprise Research Institute www.deri.ie 2 of 15 Overview Objectives The Social Semantic Desktop  Realisation  Layers  Evolution  The NEPOMUK Project context  Example: Personal Information Management  Potential Demo  Integration into the Knowledge Workbench – Semanta  Extension of the Operating System – NEPOMUK-KDE Conclusion

3. Digital Enterprise Research Institute www.deri.ie 3 of 15 Objectives The very core objective of the Social Semantic Desktop (SSD) is  Data interoperability  Structured Data based on Semantic Web technologies

4. Digital Enterprise Research Institute www.deri.ie 4 of 15 Realising the Social Semantic Desktop Desktop: Help individuals in managing information on the Web/their PC Semantic: Make content available to automated processing Social: Enable exchange across individual boundaries acquaintance Social semantic peers peers Personal Semantic Web:a semantically enlarged intimate supplement to memory Social protocols and distributed search Email Person Topic Project Document Image Event Person Claudia friend Marie PIMo colleague Keith PIMo
