This paper analyzes the tunnel problem during the best-first search strategy, designs and realizes an ontology based theme crawler system. 分析了最好优先搜索策略中遇到的隧道问题,设计并实现了一种基于本体的主题爬虫系统。
As feasible solution sets of this problem can be organized as a tree structure, we use Best-First search strategy ( BF) to traverse the tree, for which we propose an effective heuristic rule called k steps exploration. 将问题的解空间组织成树型结构,利用启发式规则&k步探测法对结点的可能分支进行评估,采用最佳优先策略搜索解空间树。
Attrib-ute reduction of rough set often employs a Best-first search, Based on mutual information of attribute set, a forward Beam search-based attribute reduction algorithm for rough set is presented. 粗糙集属性约简通常采用Best-first启发式搜索。本文运用属性集互信息作为属性约简度量,提出了前向Beam搜索粗糙集属性约简算法。
