Abstract

This paper presents the general philosophy, features and few aspects related to the implementation and underlying technologies of MaGIA, an Internet-based multi-user system designed for a collective and collaborative construction of knowledge models represented as concept maps. The use of the system can cover a wide range of purposes, from a theoretical discussion and construction of formal models to a support for collective brain-storming . What makes MaGIA an interesting tool is the emphasis put on a collective construction of such maps. In fact, one of the distinctive features and objectives of the system is to offer an enabling tool for a multi-user, bottom-up construction, where users can intervene, freely contribute and extend concept maps and where collective and collaborative multi-user map construction can take place in asynchronous as well as in synchronous way.
