Topology Preserving Word Cloud Visualization Algorithm for Cross-Language Replacing

Abstract: The word cloud may be unstable when replacing some words or even all words from it. This paper presents a visualization algorithm to solve the problem and ensure that the fial topology of the cloud will be totally consistent with the original one. The algorithm can be congcluded as follows. Firstly, all the words are scattered in the cloud to avoid overlapping. Secondly, the Delaunay Triangulation may be used on the words to obtain the mesh which can make sure the topology not be destructed after the last step being executed. Fingally, the words are compacted on the basis of the comtrol mesh to reduce the empty space. Then the final layouts of the word cloud may be formed.This paper may take the situation that all the words may be translated in other language for example to introduce the method in detail. The algorithm is a new breakthrough in keeping the stability and topology of the word clouds.#br# Ketwords: topology preserve; words replace; cross-language; scatter words; words compaction
