Abstract

This paper describes a method to visualize contrast information about two targets the Frequency and Co-occurrence Trend (FACT)-Graph. FACT-Graph is a method to visualize the changes in keyword trends and relationships between terms over two time periods. We have used FACT-Graphs as comparison method between two targets in previous research; however, the method cannot compare them as equals. To visualize contrast information, we combine two FACT-Graphs generated from different viewpoints and express the features in one graph. In case study by using 132 articles from two newspapers, we compare topics such as politics and events in them.
