Heuristic evaluation of visualization of the semantic searching economic information the comparative analysis of four experiments

The main goal of this paper is to discuss the research on heuristic evaluation of visualization in the semantic search of economic information. It is already the fourth experiment with participants. This time in the research we used two applications built in Protégé 4.1: for analysis of Return on Investment (ROI) indicator according to Du Pont model and for multidimensional early warning system. In the article we briefly described semantic networks as visual interface and premises of conducted study. Then we analysed and compared results of these experiments. Finally, we presented conclusions.
