INTEGRATING FACT-GRAPHS FOR COMPARISON ANALYSIS BASED ON TF-IDF WEIGHT

摘要

This paper describes a method to visualize comparison information about two targets by using FACT-Graph. FACT-Graph is a method to visualize the changes in keyword trends and relationships between terms over two time categories. We have used FACT-Graphs as comparison method between two targets in previous research by using two FACT-Graphs; however, the research cannot compare two targets as equal because one graph specialize in showing one characteristics. To visualize contrast information, we combine two FACT-Graphs generated from different viewpoints and express the features in one graph based on TF-IDF. In case study by using 132 articles from two newspapers, we compare topics such as politics, economics, and broadcasting in them.
