The ISO standard ISO-IEC 13250 – Topic Maps – provide a bridge between the domains of knowledge representation and information management. Topics and topic associations build a structured semantic link network above information resources. This research aims at visualizing this semantic layer efficiently, which is a critical issue as topic maps may contain millions of topics and associations. This paper has 3 parts. First, we depict briefly basic Topic Maps concepts. Then, we review a few topic map visualization techniques. Finally, we describe the visualization tool we developed and study how this tool may be used – and enhanced – for Topic Maps visualization.
