Recently, we have designed a Web-based application to visualize the spatiotemporal evolution of Web related research topics (See the previous blog here). In this application, a word-cloud-based timeline has been employed to visualize the evolution of research topics on the Web. While word clouds have been a popular way to display the prominent terms, they are unable to reveal the relations among the research topics.
