Abstract: The present invention provides a system and method for effective and in-depth contextual online collaboration using mind maps. More particularly, the present invention provides the implementation of the “Quasi-Synchronous Collaboration” using collaborative mind map either in a hardware or software form or in the combination of both. The system and method referred as “Quasi-Synchronous collaboration” use collaborative mind maps for online collaboration overlaid with structured/per-defined communication providing advantages of both synchronous and asynchronous collaboration between various users for various purposes. Advantageously, the present invention could be used in several domains including the domains of e-learning, online demand/supply aggregation, project/program management, brainstorming, content creation, content review, etc.
