A Knowledge Ecosystem (KE) refers to a system of interconnected components that work together to create, share, and use knowledge. It includes the processes, tools, and platforms that support the creation, dissemination, and application of knowledge. A knowledge ecosystem's main attribute is to generate new knowledge and valuable open-ended solutions for the participating actors that drive innovation, improve decision-making, and support learning and growth. This paper provides an overview of the knowledge ecosystem concept, which gain traction in recent research, with a focus on how the knowledge ecosystem is organised and the relationship between components. This paper contributes to research on knowledge ecosystems by describing not only knowledge ecosystem forms of organisation, but also the main methodological approaches used in the evaluation of the concept.
