Summary	Quadruple Helix analysis extends the Triple Helix of university-industry-government relations by adding a fourth helix—the media-based and culture-based public, civil society, and users—as a constitutive actor in innovation. It frames innovation as a 'Mode 3' fractal ecosystem in which knowledge is co-produced across multiple spheres, and it situates this within a broader N-tuple generalisation that can add further helices such as the natural environment in the Quintuple Helix.	Co-word analysis is a scientometric technique that quantifies how often pairs of keywords, subject terms, or title words appear together across a corpus of publications. By treating simultaneous occurrence as a proxy for conceptual relatedness, it constructs networks and clusters that reveal the intellectual structure, dominant themes, and emerging sub-fields of a research domain.
