Txt2vz: A New Tool for Generating Graph Clouds

Part of the Lecture Notes in Computer Science book series (LNCS, volume 7735)


We present txt2vz (, a new tool for automatically generating a visual summary of unstructured text data found in documents or web sites. The main purpose of the tool is to give the user information about the text so that they can quickly get a good idea about the topics covered. Txt2vz is able to identify important concepts from unstructured text data and to reveal relationships between those concepts. We discuss other approaches to generating diagrams from text and highlight the differences between tag clouds, word clouds, tree clouds and graph clouds.
