To execute creative thinking and working process, designers need to reference a lot of information and data. Internet is a good resource for creation because it is easy to be accessed and contains diversified and enormous information. With specialized digital archival contents, the archival websites founded by the government or private institutes are also resources for the designers. The creation and value-added services from many designers are often originated from these digital archives. However, current search results from these digital archives are mainly displayed in the form of tables or lists sequentially. It is a hard work for the designer to find the relevance or importance among the retrieved results. The purpose of this research is to develop a network-based information visualization model to display the searched results from digital archives based on the concept of mind map. Current tools for creating mind maps lack the support of knowledge inference. The visual features of mind map are included in the proposed system to aid the designer user for stimulating ideas and creativity. Relational inference models are implemented to provide archival search and browse. The result of this research is a tool to aid the designers to develop their creative concept by searching related content within a mind map based graphical interface. The user experience and the productivity of creation of the tool is enhanced by providing more intuitive and friendly user interface.
