Toward Visual Analytics of Unlinked Documents by Textual Analysis and Network Visualization

摘要

We describe a tool to analyze unlinked documents by visualizing networks extracted using textual analysis. Our focus is on developing an interactive visual analytics tool that enables a user to interactively observe data to detect features of the documents that may be known or unknown in advance. We have tested our tool using two data sets, one consisting of 1000 documents and the other of 360 documents. The resulting visualization showed that our tool provides a simple yet powerful method to identify trends and to find facts in the documents quickly due to its interactivity.
