Science Linkage (SL) means knowledge transmission between technological invention and basic science research. Based on the bidirectional citation between papers and patents, SL can be measured by the corresponding relationship between patents-owned 4-IPC category and paper disciplines. However, papers cited by patents are not all about basic research and ignores the hierarchical structure of natural science system which includes basic science, technical science and engineering science. 4-IPC is not accurate enough to identify technology, and the corresponding relationships between technical domains and scientific disciplines can hardly be established. This paper studies the subject hierarchy of the science and 4-IPC category refinement of the technology, and improves the detection of SL information science method. It takes the experiment of bidirectional citation between papers and patents of American catalytic technology from 2006 to 2009. The results show that the corresponding relationships between technical domains and scientific disciplines are established to more clearly present SL picture.
