摘 要: 采用路径离散化规则,结合XML半结构化的特点及概率知识,融合粒子群算法与蚁群算法,提出一种优化XML数据查询的概率方法,采用粒子群算法快速生成信息素分布,利用蚁群算法精确求解,达到了优势互补,提高了数据查询的范围和收敛的效率。仿真实验表明这种融合方法具有更好的查询效果。 This paper adopted path scatter rule to combine'tX30 with ACO to improve XML probabilistic query which adopted PSO to make pheromone distribution and made use of ASO to get a value accurately, as a result it developed enough advantages of the two algorithms and the data query range was widen and convergence efficiency was increased. Through simulation experiments, it shows this combine method has a preferable query effect.
