As part of the OLnet project, and the Collective Intelligence sub-project an Open University team has prioritised the COP15 climate change conference, as a mini-experiment to put the Cohere semantic annotation and connection tool through its paces. This is part of our project's mission to research the impact and evidence base of the OER movement, and build its capacity via different forms of collective intelligence. Our specific interest is in experimenting with infrastructure to facilitate OER/CI (Open Educational Resources/Collective Intelligence) the latest update to the Cohere Mozilla Browser Add-On, which provides Diigo/Sidewiki-like web annotation as an addition to semantic connection making and map visualization.
