Abstract [en]

There exist lots of text data. They are often extracted into topical tags for indexing. They are also connected by relationships like sharing the same authors, created at the same period. The entirety of above yields a big text network. In this thesis, a visualization tool to reveal information from big text data in the network is introduced. With clustering algorithm, the data are grouped. The groups with tag clouds show the overview of dataset. Edge halo, a new approach for bundling edges, represents the relationships of text data in and between the groups. An application prototype was developed to visualize clustered text data with their relationships and give an overview of the network in one view.
