摘要
针对目前上下文规则生成方法通常是依靠人工定义的,提出一种修正的ID3算法用于虚拟环境上下文规则的自动生成.该算法先构建上下文决策树,然后再将此树自动转换成规则集.实验结果验证该算法在生成规则的有效性与计算效率上具有良好性能.
The current generation methods of context rules were usually dependent on manual definition,which could cause lots of problems.Therefore,the modified ID3 algorithm was proposed in this paper to automatically generate context rules based on virtual environment.It was to build a context decision tree and then convert this tree into rules set.The experimental result showed that this algorithm had a good performance in effectiveness of generated rules and computational efficiency.
