On account of inaccurate classification, the traditional hierarchical Webpage recommendation algorithm based on vector space model can not produce high precision when it deals with large amounts of data.

在面对大数据量时，传统的基于VSM的分层网页推荐算法由于分类的不准确，造成推荐精确率较低。该文针对这个缺陷提出了改进的分层推荐算法，该算法在推荐过程中综合考虑了领域和用户兴趣，以及网页和用户兴趣的相似程度，来为用户提供高效的个性化网页推荐。

To extract shaft orbit\'s features invariant to rotation, scaling and translation, the unique strengths of Haar orthogonal matrix type are found, the horizontal and vertical coordinates of shaft orbit are fast proceeded by Haar transform, respectively, and the slopes with different resolutions are obtained at different positions by using the corresponding transform coefficients, and then the multi-resolution angles between the adjacent slope straight line are extracted skillfully and used for the hierarchical recognition, the recognition process accords with the principle of human\'s recognizing things by using hierarchy analysis approach.

为提取轴心轨迹平移、旋转、尺度不变性特征，本文挖掘出Haar正交矩阵在图形识别中的独特优点，引入Haar正交矩阵分别对轴心轨迹的横、纵坐标进行快速变换，并利用变换后的对应系数得到轴心轨迹不同位置不同分辨率下的斜率，继而推求出相邻斜率直线之间的多分辨率夹角，所获夹角用于轴心轨迹的分层识别，其识别过程符合人类识别事物层次分析的规律。

社会代谢多尺度综合评估&分析方法，根据&人类活动&资源、&体外能&资源和&增加值三者在社会经济系统中的叠合关系，将各个尺度（如国家、经济部门、次级部门、省/州、社区、直至个别家庭）上，社会经济系统的能量代谢过程，与该系统的经济、人口（如人口的年龄结构和性别构成）、生态和社会（如义务教育和退休年龄的规定）特征结合起来，利用多个关系式，计算出社会经济系统的人类活动量、体外能投入量、劳动生产率、生物—经济压力和体外能超循环强度等参数、指标，进而综合地分析评估社会经济系统发展与可持续性。

A hierarchical IDbased proactive threshold signature scheme is presented. The scheme has the structure of hierarchical PKGs, so a lowerlevel PKG can share the workload of secret information generation and identity authentication with a higherlevel PKG. At the same time the scheme has the property of proactive security, that is, the whole lifetime of signature is divided into several time periods, and the shares of private key need to be renewed in each time period.
