摘要
基于共词分析技术,结合《中文医学主题词表》(CMeSH)和中国生物医学文献数据库(CBM)自身特点,提出基于主题词共现构建全新中文医学概念空间,重点探讨共现主题词相关度计算算法,测试结果较佳,在一定程度上可降低CBM非专业用户对CMeSH的认知负担。
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 resuh shows that this method is effective, and it can reduce cognitive burden of CMeSH for non - professional users to some extent.
