By combining the NTSTATUS into a single 32-bit numbering space, the following NTSTATUS values are defined. Most values also have a defined default message that can be used to map the value to a human-readable text message. When this is done, the NTST…
BACKGROUND OF THE INVENTION FIG. 1A is a simplified block diagram schematically representing a typical prior art network router 10. Packet forwarding router 10 includes two major subsystems: control plane 12 and data plane 11. Data plane 11 provides…
1 LSA Introduction LSA(latent semantic analysis)潜在语义分析,也被称为LSI(latent semantic index),是Scott Deerwester, Susan T. Dumais等人在1990年提出来的一种新的索引和检索方法.该方法和传统向量空间模型(vector space model)一样使用向量来表示词(terms)和文档(documents),并通过向量间的关系(如夹角)来判断词及文档间的关系:而不同的是,LSA将词和文档映射…
