Introduction

• SlideWiki is a platform created as a proof of concept for CrowdLearnconcept.▫ The CrowdLearn concept exploits the wisdom, creativity and productivity of the

crowd for the creation of rich, deep-semantically structured E-Learning content. With SlideWiki users can create and collaborate on educational slides, diagrams, assessments and arrange slides in presentations. Presentations can be organized hierarchically, so as to structure them reasonably according to their content.

• SlideWiki empowers extremly large communities of instructors, teachers, lecturers, academics to create, share and re-use sophisticated educational content in a truly collaborative way. In addition to importing PowerPoint presentations, it supports authoring of interactive online slides using HTML and LateX. Slides and their containers (called Deck), are versioned thereby enabling change tracking. Users can create their own themes on top of existing themes or re-use other's themes.

• SlideWiki is developed and maintained by AKSW research group at University of Leipzig.

SlideWiki for Humanity

• Education is one of the main factors for societal progress (in the Human Development Index, for example, education) is weighted one third)

• However, despite huge investments into e-learning the potential of the Internet and crowd-sourcing techniques for e-learning is still not sufficiently explored

• With SlideWiki we aim to dramatically improve the efficiency and effectiveness of the collaborative creation of rich learning material for online and offline use

• With its semi-automatic translation and liberal licensing SlideWiki aims to make educational content dramatically more accessible to learners in developed and developing countries
