To improve the clustering quality of massive XML document sets, an adaptive clustering algorithm with chaos of XML document sets was proposed based on PSO （ACPSO）. To predigest similarity judgment of XML document, the algorithm is based on xml keys, chaos principles and PSO to carve up XML documents by similarity distance. While enhancing the algorithm＇s astringency, with some parameters of organize-self clustering learning and power gene optimization, the algorithm swells the capability to seek the optimization in the full XML document, and...
