| Abstract: | Purpose/significance] The technology theme map is one of the effective methods to carry out the technical analysis and technical route tracking. To draw a technology theme map more economically and clearly,an economic method of drawing a technology theme map is proposed. Method/process] Fruchterman-Reingold and VosMapping algorithm were used to compute keywords.Then, a plane pixel density function was uesed to draw a map.Result/conclusion] The software including data processing, node layout, graphics rendering, human-computer interaction based on the proposed method is designed. The method is applied to the 3D printing patent in China. The results show that the method is simple and effective. |
