Knowledge selection(KS)is a completely new method.KS is realized by three filters:Identification selects knowledge items according to syntactical properties of the query,adaption uses background knowledge for the filtering,and prediction tries to predict future queries for a small number of time steps.In this paper neural network solutions for KS together with an KS in a computer security application.

知识选择 ( KS)是一种全新的方法 ,其过程由三个滤波器实现 :( 1)辨识过程 ,即根据查询的组合属性选择知识项。 ( 2 )自适应过程 ,即为滤波而使用相关的背景知识。 ( 3 )预测过程 ,即提前几步预测未来的查询。本文提出了用神经网络求解 KS问题的方法以及 KS在计算机安全领域的应用方法

Intelligent learning is an issue that network-based education reseachers trying to tackle without suitable solution.Guiding a learning process by a traditional navigator or by searching engine has the inherent weaknesses.This paper has a new effective solution:guiding the learning process through the mapping of knowledge items to knowledge domain,which is based on the definite way of knowledge organizing and presenting.This method,after the authority of knowledge by domain -specific expert,applies an association rule to cluster definited knowledge items ,to present similarities or associations,and to give the learner an intelligent clue of association learnig.

e-Learning中的智能化学习一直是诸多网络教育研究人员努力去解决而至今尚未有合适解决方案的一个问题。采用传统的导航方式或搜索引擎方式引导学习过程有着自身固有的缺陷。一种新的引导方式是:基于知识指定的表示和组织方式,以知识项和知识交流域(上下文)的映射来引导学习过程。这种方式以知识项得到领域专家认证为前提,通过关联规则对知识进行有效的聚类,给出一系列相关的知识项(相关案例或有关内容),向学习者提供建议性的学习内容,方便了关联学习。

A context-centered design knowledge management technique was proposed to improve reuse efficiency of design knowledge. Design context was defined as application environments of the design knowledge, which included current design task and current designer's attributes. Two essential components were a three-layer design process model comprising collaboration layer, intention layer and behavior layer and a user model combining a stereotype model and an overlay model. Workflow, tree hierarchy and hierarchical automaton were adopted to represent the above-mentioned three layers respectively. In user modeling, model stereotypes were classified and matched according to user properties and template contents would be defined based on domain knowledge architecture. The proposed technique employed context to facilitate the active recommendation of design knowledge items, which reduced negligence of key knowledge items and time to search for them. It offered wide application prospects and low cost of implementation without having to formalize the details of knowledge items or change their original formats.

为了提高设计知识重用的效率,提出了一种以上下文为中心的设计知识管理方法。设计上下文指设计知识被利用的环境,包括当前设计任务和当前设计者的属性。该方法的核心内容有两个方面,即协调-意图-行为三层设计过程建模以及模板和覆盖相结合的设计用户建模。协调层、意图层和行为层分别采用工作流、树形结构和层次自动机表示。在用户建模中,采用用户属性对模板进行分类和匹配,并且基于领域知识体系结构定义模板的内容。该方法利用上下文实现设计知识的主动推荐,可减少重要知识的遗漏和缩短查找时间,不需要对设计知识的内容进行形式化的描述和对知识的格式进行转换,通用性强,实现代价小。
