This workshop is about exploring a web-based tool (analytics workbench) that can be used to collect information about citizen science projects. It is based on current work in the European CS Track project, which seeks to increase the knowledge on CS using web-based analytics (computational analyses based on projects’ manifestations on the web and social media) and questionnaires, combined in a multi-perspective analysis.
