Abstract Based on co-occurrence analysis, combining the characteristics of Chinese Medical Subject Headings(CMeSH) and Chinese BioMedical Literature Database(CBM), the paper proposes a new method of constructing Chinese medical concept space, mainly discusses the calculation algorithm for relevance of CMeSH terms co-occurrence. And the test result shows that this method is effective, and it can reduce cognitive burden of CMeSH for non-professional users to some extent.
