摘要
针对因特网统一资源标识符缺乏自然语言语义的局限,研究基于角色、资源空间层次和本体的网络科技信息资源定位和导航技术,其特点是定位标识符具有自然语言语义,用以描述浏览者角色、对资源的类别需求以及资源内容相关的知识陈述对象和知识量纲。在服务器端相应地建立这些参数的认知方法,进而实现基于语义认知的网络科技信息资源定位和导航。
Aiming against the shortage of semanteme in URI of the resources of scientific and technological information in Internet, the research constructs an URI which comprising the semanteme of natural language for describing the role of browsers, the requirements of classes of the locating and navigating resources as well as the subjects and dimensions of the knowledge relevant to contents of the resources. Correspondingly, the server is designed to cognize the parameters in order to locate and navigate the resources by semanteme-cognition.
