语义

Relativity,similarity,and contrariety are three ways of the thinking association.

文章把负值引入到相似度计算中，提出对立度等概念和相关的计算模型，将它们运用到语义对立程度的计算中，并通过仿真试验论证了这些概念模型和计算方法的可行性和有效性。

Context is a set of contextual factors that influence the conveyance of meaning and its expression.

语境是指影响语义和表达的一系列主客观因素。

This thesis is focus on the dynamic service composition based on the semantic Web, the aim is to compose the various Web services automatically according to the demand of customers, and to complete the task corporately; this can make the services meet the demand of the customers neatly.

本文研究的是基于语义的Web服务自动组合技术，目标是能根据用户的需求将各种己有的Web服务自动地组合起来、协同工作完成用户的任务，使服务可以灵活地满足用户的需求，实现"按需服务"。

The experimental system extract the low-level features of images such as HSV histogram, the texture got from coexistence matrix, color correlogram, and according to the characteristic of our image database, design the evaluation function such as the average rank ratio to evaluate and compare the performance of different integration of different features including semantic, and validate the active effect of feedback using experiment results.

该原型系统提取了HSV直方图、共生矩阵纹理、颜色相关图等底层特征，同时根据图像数据库的特点，设计了平均位置比值等评价函数对语义特征与底层特征的各种结合的检索性能进行了比较分析，并对反馈效果进行了实验验证。

This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。

This thesis attempts to contrast the religion beliefs , literary allusions and daily life of sources, culture-bound words of sematics through similar and different analysis by display a lot of facts, trying to prove their similarities and differences.

本文拟从英汉习语的宗教信仰，文学寓言与日常的来源，习语的语义角度作共性与个性对比研究，用大量的事实证明英汉习语所具有的共性和个性。

When tfansparencies were balanced, the cumulative morpheme frequency effect was found only in high surface frequencywords but not in low frequency words.

通过变化汉语合成词的词素累积频率的方法，考察表面频率和语义透明度对加工速度的影响。

Based on public meta model of CWM, the updated strategy provides consistent understanding of each semantic of metadata.

改进后的策略基于CWM公共元模型的方式，提供了每个元数据语义的一致理解，可以实现公共元模型和自身元模型的转换，不需要在每个元模型之间都建立一个元数据桥，从而降低整体的开销。

First, according to the specialities of CWM metamodel and metadata, description logic DLid which supports identification constraints on concepts is proposed.

在基于公共仓库元模型建立元数据的过程中，参与建立元数据的团体的不同经验以及描述数据的不同视角不可避免地带来元数据的冲突和冗余等问题，然而CWM的图形化特点使之缺乏精确的语义，所以如何在其上进行推理以自动发现这些问题至今没有得到很好的解决。

When writing semantic actions, it is your responsibility to make sure that all the references do not dangle.

在编写语义动作时，你要负责确保所有引用不会悬空。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
