The meta-search engine establishes the“kernel key-word”and“multi-level weight ”concepts,and adopts the algorithm of integrating the results from basic search engines with the web page contents.

Giving as an example that a company manufactures three kinds of automobile parts,this paper introduces in detail the approach of ranked positional weights,analyzes process sequencing and its results.

A fuzzy SWRL extension named vague-SWRL is therefore proposed on the basis of vague sets,with the notion of second-degree weight introduced to modify and restrict the membership degrees of fuzzy classes and fuzzy properties.

In order to solve the security problem of digital video, a hierarchical authorization scheme on digital video is presented,which utilizes modern strong cipher to protect digital video s transport and realize hierarchical authorization.

Therefore,this article proposes an improved role-based hierarchical authorization and access control model,which classifies users,modules permissions,as well as accessed data into a top-down tree structure and creates user-level-modules-data-level mapping to implement hierarchical authorization.

According to practice, this article describes a pattern of interactive multileveled authority for management.
