1基于关联规则进行词对齐的跨领域情感分类算法(英文)显示文摘文本情感分类被应用于企业用户管理系统,通过自动对诸如评论、博客等带有情感倾向性文字进行分析,帮助商家更好地了解用户对商品或者服务的态度。然而,评论和博客等内容常源于不同应用领域,为每个领域训练一个能准确预测情感倾向的分类器非常困难。主要原因是,在不同领域,人们通常会用不同特征词表达相同情感,并且难以找到一个直接的映射函数,以建立不同领域特征词间的映射关系,从而消除领域间差异。因此,将某个领域训练好的分类器直接应用到另一个领域时,会因为领域间差异使得分类器准确率急速下降。本文提出一个新的基于关联规则进行特征词对齐的跨领域情感分类算法,该算法通过在同一领域中挖掘具有强关联关系的领域共享词和领域专有词词对,建立直接映射关系,并以领域共享词为桥梁,在不同领域的特征专有词之间建立间接映射关系,从而在一定程度上消除了源领域和目标领域之间的差异,有效提升了跨领域情感分类准确率。在亚马逊数据库上的实验结果证明该算法提高了跨领域情感分类性能。Xi-bin JIA Ya JIN Ning LI Xing SU Barry CARDIFF Bir BHANU 2018Frontiers of Information Technology & Electronic Engineering2018,19,2:4
2ISBT—128码的应用状况显示文摘1994年ISBT会议批准了一项有关条形码和血液制品标签的国际标准,该项标准可以提供全球唯一的数码标识和国际标准化产品代码。本文提供了最新的ISBT-128码的使用情况:ISBT-128码已经成功地在一些国家得到应用,而且许多国家也正在使用或准备推行ISBT-128码标准。同时标准的本身也被延伸用于为血液成分(Blood Components)提供代码,以及为组织库提供代码和标签的标准。希望本文所提供的信息能够鼓励其他国家采用这项成功的、高规格的标准。ISBT-128码和ICCBBA有限公司GeorgsenJ Odense Ashford R Cardiff Steane E NashvilleTN 盖安清 沙捷 2002国外医学(输血及血液学分册)2002,25,1:3
3RATIONAL BASIS FOR SUSPENDED SEDIMENT MODELING显示文摘This paper presents a rational basis to model the transport of suspended sediment. The looseboundary condition for 3D models and the adjustment coefficients for both the depth-integrated 2D and laterally integrated 1D models are treated comprehensively. A combination of Dirichlet and Neumann conditions is proposed as the loose-boundary condition. The adjustment coefficient for 2D models is obtained on the basis of the proposed boundary condition and analytical solutions developed for some simple cases of non-equilibrium transport of sediment in uniform flows. The adjustment coefficient for 1D models for natural rivers is further obtained from lateral integration. Comparisons with analytical solutions and a considerable amount of laboratory and prototype data show that mathematical models developed along the proposed line of attack would well simulate the transport of suspended sediment in practical problems.Jianjun ZHOU, Biniiang LIN and Bingnan LIN Prof, Dept. of Hydraulic Eng., Tsinghua University, Beijing 100084, P.R.
