Manual extraction of information from the biomedical literature-or biocuration-is the central methodology used to construct many biological databases. For example, the UniProt protein database, the EcoCyc Escherichia coli database and the Candida Genome Database (CGD) are all based on biocuration. Biological databases are used extensively by life science researchers, as online encyclopedias, as aids in the interpretation of new experimental data and as golden standards for the development of new bioinformatics algorithms. Although manual curation has been assumed to be highly accurate, we are aware of only one previous study of biocuration accuracy. We assessed the accuracy of EcoCyc and CGD by manually selecting curated assertions within randomly chosen EcoCyc and CGD gene pages and by then validating that the data found in the referenced publications supported those assertions. A database assertion is considered to be in error if that assertion could not be found in the publication cited for that assertion. We identified 10 errors in the 633 facts that we validated across the two databases, for an overall error rate of 1.58%, and individual error rates of 1.82% for CGD and 1.40% for EcoCyc. These data suggest that manual curation of the experimental literature by Ph.D-level scientists is highly accurate. Database URL: http://ecocyc.org/, http://www.candidagenome.org//
从生物医学文献中手动提取信息——即生物编目——是用于构建许多生物学数据库的核心方法。例如,通用蛋白质数据库(UniProt)、大肠杆菌数据库(EcoCyc)和白色念珠菌基因组数据库(CGD)都是基于生物编目构建的。生命科学研究人员广泛使用生物学数据库,将其作为在线百科全书,作为解释新实验数据的辅助工具,以及作为开发新生物信息学算法的黄金标准。尽管一直认为人工编目高度准确,但我们只知道之前有一项关于生物编目准确性的研究。我们通过在随机选择的EcoCyc和CGD基因页面中手动选择经过编目的断言,然后验证参考文献中找到的数据是否支持这些断言,来评估EcoCyc和CGD的准确性。如果在为某个断言引用的出版物中找不到该断言,则该数据库断言被视为错误。在我们对两个数据库验证的633个事实中,我们发现了10个错误,总体错误率为1.58%,CGD的个别错误率为1.82%,EcoCyc的个别错误率为1.40%。这些数据表明,由博士水平的科学家对实验文献进行人工编目非常准确。数据库网址:http://ecocyc.org/,http://www.candidagenome.org//
