依赖属性约减
1.
Before services matchmaking, according to service request, OGSDA-RS performs the standardization of service request, irrelevant properties reduction and dependent properties reduction.
针对网格服务发现的查全率、查准率效率较低的现状,基于本体技术和粗糙集理论,设计了一个服务发现算法OGSDA-RS,在服务匹配之前先进行3步预处理操作:规范化请求服务,根据请求服务对发布服务进行不相关属性约减和依赖属性约减。
补充资料:非贴壁依赖性细胞
分子式:
CAS号:
性质: 无需贴附到固体介质上就能生存和生长的细胞。但在培养时,有的细胞常可不牢固地贴附在固体介质上。来自血液、淋巴系统的细胞和大多数肿瘤细胞常为非贴壁依赖性的。他们的形态呈圆形。
