This project cut down the quantity of campaigner of index word and reduces the complexity of automatic indexing in pre-processing.(2) Based on analyzing the relevance of index word, the paper presents a new text categorization model, which is based on the relevance of index term.

这该方案以帕欧理论为依据，减少了自动标引过程中预处理信息量，从而降低了文本标引的复杂度；(2)在对标引词的相关性进行全面分析的基础上，提出了一种新的文本分类的模型——基于标引词相关度的文本分类。

Question about the relation between explanation and context. Around those questions the author goes on the account, and investigates Aristotle's full but coarse idea, Hempel's covering laws model that is logically tight, Salom's fully objective statistical-relevance model, Fetzer's causal relevance model that provides adequate answers to ontic question and epistemic question.

本文就是围绕这三个问题展开论述，考察了亚里士多德粗糙而全面的看法、亨佩尔的逻辑严谨的"覆盖律"模型、萨尔蒙的完全客观的"统计相关"模型和费茨尔的在认识论和本体论两方面可称完备的"因果相关"模型。

This paper introduces some common query expansion approaches in relevance feedback based on probability model and vector space model,then a new term selection method is introduced based on language model,which takes into account two features of expanded terms-"relevance"and"coverage".

本文介绍了概率模型和向量空间模型下的常用查询扩展方法，并提出了一种基于语言模型的相关反馈方法，该方法同时考虑了扩展词应该具备的两个特征，即相关性和覆盖性。

本文介绍了概率模型和向量空间模型下的常用查询扩展方法，并提出了一种基于语言模型的相关反馈方法，该方法同时考虑了扩展词应该具备的两个特征，即相关性和覆盖性。在TREC测试集上对这些算法进行了比较，结果表明这种新算法在平均准确率上比传统方法有所提高。

In this paper,we define the oriented relevance information among attributes of information and decision systems,which measures the relevance among attributes of information and decision systems. And based on these definitions, we present a new discriminant theorem of knowledge reduction of information systems.

本文定义了信息系统以及目标信息系统属性之间的有向关联信息，用来度量信息系统以及目标信息系统属性之间的关联程度，基于此给出信息系统以及目标信息系统的知识约简一种新的判定定理。

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。

According to the ternary relation based on relevance theory, this thesis also attempts to define the respective roles of the author of original text, the translator and the reader of translation, and then points out that only through the coordination of the above three parties can optimal relevance be ultimately achieved and pragmatic failures be prevented from occurring in the process of public signs translation.

根据关联理论的翻译三元关系，本文也提出：源语作者、译者和目的语读者在翻译过程中各自应起到的作用，并指出只有通过这三者的协调作用，才能实现最佳关联，避免语用失误的发生。

In Relevance Theory the most important dimension of contextual appropriateness , relevance , is so defined as to make it vacuously hold for any communicative act that does not prove altogether uninterpretable

从语境合适性的角度来说，关联在关联理论中是最重要的，因此，它的界定使得它在任何交际行为的可解释性上显得空洞无物。

不同民族所具有的独特文化导致翻译工作困难重重，如何使不同的文化意象在翻译中达成统一，关联理论中的最佳关联原则给了翻译工作者很大的启发与指导。

The distinctive features of different nations result in the challenges in translation. Hence, how to achieve coherence out of diverse cultural images in translation? The Principle of Optimal Relevance in Relevance Theory serves the function of an enlightener for translators.

不同民族所具有的独特文化导致翻译工作困难重重，如何使不同的文化意象在翻译中达成统一，关联理论中的最佳关联原则给了翻译工作者很大的启发与指导。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
