A Practical Visualization Method for Multi-Dimensional Web Document Vectors

Presenting high-dimensional vectorized text set on 2D plane facilitates a quick perception of the similarity of their contents. This paper presents a practical visualization method used in Web document mining system to display the analysis result. The approach is derived from a classic algorithm. Because the original algorithm is not practical for our usage, we make a detailed analysis to the algorithm, and contribute a great improvement in order to put it into practice. In addition, this paper shows a comparative experiment acquired by our algorithm. To evaluate the algorithm we also propose a novel measurement which is supported by the positive experiment result.
