The article sets out to present conclusions from the conducted research into semantic network visualization as a user interface applied for the purpose of searching for business information. The article describes the results of the research comprising literature analysis as well as the validation of prototypes developed in Protégé. Based on the analysis of publications covering the latest research, four areas of research into semantic network visualization were identified, i.e. the development of new software, the application of techniques, technologies, and solutions making it possible to perform various operations concerning the semantic network visualization view, the verification of the use of various graphic designations, as well as users’ validation of interactive semantic network visualization. For each area, the main directions of research are specified, along with an indication of publications that describe them. Furthermore, the article provides conclusions from the validation of prototypes of ontologies for the area of users’ (experts’) analysis of economic and financial indicators using semantic network visualization. The research in question allowed the identification of three potential problems related to the use of semantic network visualization as a visual interface in searching for economic information.
