基于ⅡG和LSI组合特征提取方法的文本聚类研究

本文利用改进的信息增益特征选择方法和潜在语义索引技术组合的特征提取方法,对文本进行了有效的自动聚类.从语料库中抽取了250篇文本,首先利用向量空间模型和改进的信息增益特征选择方法,构造文本特征向量,利用C-均值方法聚类,聚类结果准确率、查全率、F-measure分别达到0.82、0.88、0.83.在此基础上,对最优的特征选择结果运用潜在语义索引方法,对奇异值分解的结果进行截断处理,发现奇异值K取40时聚类结果的准确率、查全率、F-measure达到0.95、0.57、0.78,在有效地降维的同时,大幅度地提高了聚类的准确率.

我国综合档案事业发展水平及其趋势的定量评价研究

论文应用熵权法和AR(1)模型分析了我国1991-2015年的综合档案事业发展水平及其演化趋势.结果发现:档案资源建设水平、档案开放利用水平和组织建设水平发展的步调不尽相同并表现出明显的阶段性特征;国家综合档案事业发展水平总体上呈稳步上升势态,但阶段性发展特征同样明显;国家综合档案事业发展水平滞后于同期经济发展水平;综合档案事业发展水平的绝对发展速度受制于上年度的绝对发展速度.     

社会化与产品化:档案学实践教育资源开发路径研究——以福建师范大学为例

档案学实践教育资源社会化开发与产品化运用模式,以高校-学生培养为中心,社会-企业需求为导向,市场-产品运用为基础,凝聚高校-社会-市场三维组织优势合力,其中社会化开发缩小了高校和社会之间的距离,产品化运用则是通过市场来对高校实践型、重技重能教育理念回归的重新确认,对提升档案学专业实践教学的整体水平以及培养技术型、应用型高级档案专业人才具有重要意义.

Understanding the Nature,Uses, and Gratifications of Social Television: Implications for Developing Viewer Engagement and Network Loyalty

This study employed an online survey (N = 310) to explore how viewers’ motivations for social TV participation influence their involvement in social TV activities, their program commitment, and network loyalty. Findings show that social infotainment and social companionship are the primary motivations of social TV participation. However, only social infotainment significantly predicts the intensity of viewers’ social TV usage, which has a positive influence on program commitment and network loyalty. Additionally, the relationship between social TV usage and network loyalty is partially mediated by program commitment. These findings demonstrate the value of social TV to broadcasters and provide directions for initiating and maintaining long-term relationships with viewers.     

High-entropy-alloy nanoparticles with 21 ultra-mixed elements for efficient photothermal conversionOA

Multi-metallic nanoparticles have been proven to be an efficient photothermal conversion material, for which the optical absorption can be broadened through the interband transitions(IBTs), but it remains a challenge due to the strong immiscibility among the repelling combinations. Here, assisted by an extremely high evaporation temperature, ultra-fast cooling and vapor-pressure strategy, the arc-discharged plasma method was employed to synthesize ultra-mixed multi-metallic nanoparticles compose...     

Photonic orbital angular momentum with controllable orientation

Vortices are whirling disturbances, commonly found in nature, ranging from tremendously small scales in Bose-Einstein condensations to cosmologically colossal scales in spiral galaxies. An optical vortex, generally associated with a spiral phase, can carry orbital angular momentum (OAM). The optical OAM can either be in the longitudinal direction if the spiral phase twists in the spatial domain or in the transverse direction if the phase rotates in the spatiotemporal domain. In this article, we demonstrate the intersection of spatiotemporal vortices and spatial vortices in a wave packet. As a result of this intersection, the wave packet hosts a tilted OAM that provides an additional degree of freedom to the applications that harness the OAM of photons.
