be risen

9. Towards Solution
Supporting
Self- One silver-bullet solution seems unreasonable due to the
Organization
in Politics by regional, cultural, and legislative differences

Technologies
The more appropriate way to rise an impact may be to link
existing systems together

Introduction
Ability to collaborate and problems with information

Schema overflow can be addressed by a better recommendation of
Ontopolis users or content, respectively
Portal
Conclusion
The combination of social web and knowledge technologies
seems to be a natural step to tackle these issues
Our main aim has been to create a social-semantic web
platform enabling its users to collaboratively create
solutions of public issues and to self-organize around these
solutions
