[Purpose/significance] This paper aims at proposing a method of using the natural language processing technology to study contents based on the scientific and technological planning to automatically build the frontier theme map. [Method/process] First, this paper used information extraction and topic recognition technology in the field of natural language processing to mine the topic of scientific and technological planning texts. Then, it used the java language development tools to construct the scientific research frontier theme map, and visually display them. [Result/conclusion] The empirical study on the field of carbon nanotubes has proved that this method can draw the forefront of scientific research in this field comprehensively, quickly and accurately.
