Dependence measures, including linear correlation coefficient and concordance measure, are traditional methods.

相关性度量，包括线性相关系数和和谐性相关性度量是传统方法。

Quantifying similarity/difference between two objects plays an important role in many contexts The quality of the similarity/difference scores can be improved by considering the semantic information related to the features of objects A flexible semantic distance function called X Dist is proposed, which can utilize the semantic information to measure the difference between two objects based on a solution to the transportation problem from linear optimization With a ground distance function for single features being a metric, X Dist is also a metric This property is very useful for making searching efficient, but is not investigated in the previous research Moreover, the experimental results show X Dist can be as good as the previously studied similarity measures in nearest neighbor searching, discriminative power and computing speed

量化对象间相似性/差别的方法具有广泛的用途，利用相关的语义信息能够得到更好的量化结果提出了一个量化对象间语义差别的距离函数XDist，它基于线性优化中的运输问题模型和相关的语义信息量化两个对象之间的差别在量化特征的差别函数是度量的情况下，XDist是一个度量，在提高搜索的效率方面具有优势，弥补了以往研究的不足，而且实验初步表明，此函数在最近邻查询效果、差别分辨力和计算速度方面能与已有函数相媲美1 引言量化对象间相似性/差别的方法具有广泛的用途，例如数据挖掘中的聚类；信息检索中的相似文档查询；协同过滤中的相似用户查询；CBR中的相似案例查询集合是对象特征表示的常用结构，集合的元素是与对象特征相关的项，它们可以

The PSP uses LOC, and many metrics are based on that assumption.

使用LOC代码行度量，所有的度量过程都基于这个标准。

During the transformation, there are two main forces: modern investment theory and IT. Modern investment theory led investors to accept the idea of risk management. Besides, it brought the instruments measuring risks and pricing risk assets, which promoted market participant to understand derivatives very well. IT provided powerful technical support for massy calculations which is necessary for risk measurement and pricing and for instant reaction capacity to market opportunities.

在这一转化过程中，现代投资理论和信息技术是两大主要推动因素，现代投资理论不仅使风险管理的理念深入人心，还具体提供了风险度量和风险资产定价的工具，增强了市场参与者对衍生金融工具的认知能力，信息技术则为风险度量和风险资产定价所需的深度计算，以及对市场机会的迅速反应能力提供了强大的技术支持。

Concept semantic space and similarity measure based on it Concept semantic space and similarity measure based on it is proposed.

概念语义空间与相似性度量提出了概念语义空间的概念及其建立在该空间基础上的相似性度量。

A hybrid measure based on space color histogram and correlation measure was introduced.

实验表明，它弥补了传统直方图L〓度量的不足，是一种性能良好的颜色直方图度量。

I smile at your play with that little bit of a broken twig.

我微笑着看你玩那一段小小的树枝。

They may be produced for almost any shaft angle.
