【摘要】 因特网上蕴藏着丰富的生物医学信息资源,生物医学信息资源的获取越来越多地依赖于In ternet网络。因此,开发新的描述和管理信息资源的方法,才能更好地满足人们对信息资源的需求。通过对数据库、搜索引擎、网站资源及元数据的分析,表明生物医学信息资源具有电子化、网络化、动态性、分布性、无序性的特点。利用元数据对医学信息资源进行开放的和计算机可识别的描述,有助于用户搜寻、选择、利用医学信息资源,尤其是网络医学资源。通过元数据的转换,将不同地域、不同语言、异构的资源有机地整合在一起,可以更有效地、系统地满足人们对信息的需求。更多还原

【Abstract】 With the development and utilization of computer techniques,Internet is playing an important role in information dissemination.There are abundant biomedical resources on the Internet.Accessing biomedical information is more dependent on the Internet than ever.It is important to explore new methods to describe and manage information resources.We have analyzed biomedical databases,search engines,web sites,and the metadata adopted by biomedical databases.The results show that biomedical information resources are characterized by electronic format,networking,dynamia,and dispersion.Describing a resource with metadata allows it to be understood by both humans and machines in ways that promote interoperability.Metadata interoperability has to be the underlying principle for networked information management.It directly impinges on information sharing,interchange,and accessibility across the boundaries of systems,languages,and geographic locations.We can use metadata to describe biomedical information and to integrate resources.It will benefit the people to access,select,and utilize biomedical information resources.更多还原
