Schema matching is the task of finding semantic correspondences between elements of two schemas, which plays a key role in many database applications, such as data integration, electronic commerce, data warehouse, semantic query processing, and XML message exchange, etc.

模式匹配问题是意图获得两个模式中所包含个体对象之间的语义匹配和映射，其结果表示源模式的个体对象与目标模式的个体对象之间存在特定的语义关联。

To achieve the real semantic-based image retrieval would be the most effective approach to settle the problem.

实现真正意义上的基于语义的图像检索，将是解决"语义鸿沟"问题的最有效途径。

This paper explores the similarities and differences between Chinese and English in the use of rounders through analysis of data from oral and written discourses.

从语义和语用的角度出发，对比英汉范围变动型模糊限制语的研究发现，尽管在语义和句法结构方面，英语和汉语中范围变动型模糊限制语存在一定的差异，但从语用和交际的角度分析，它们的使用有相同的语用特征，体现了语用策略的运用。

Semantic Grid is able basically to solve the problems, such as different information format in Grid, multiformity of information semanteme , pinch of information relation and non-unionize. It has higher practicability.

语义网格基本上能解决网格上存在的信息格式异构、信息语义的多重性以及信息关系匮乏和非统一等问题，具有高度的简单实用性。

Equivalence is the common goal of all translators, and it can be roughly divided into semantic equivalence...

翻译中的对等主要存在于语义层面和语用层面，也就是通常所说的语义对等和语用对等。

In order to improve the expression capability and the performance ofthe graph transformation in applying to software evolution, a softwareevolution operation description language SEOL (Software EvolutionOperation Language) is proposed, and the structured operational semantics on SEOL is studied, and then the semantic equivalence analysismethod about software evolution operation is described. To the SEOLexpression, the dissertation builds the corresponding processingmechanisms, which include the basic principles and the processing flow,and discusses the graph transformation description in SEOL.

为提高图变换在软件演化应用中的表达能力和处理性能，结合谓词逻辑，论文提出了软件演化操作描述语言SEOL(SoftwareEvolution Operation Language)，研究了SEOL语言的结构化操作语义，指出了软件演化操作语义等价的分析方法，针对SEOL语言表达式，构建了相应的处理机制，包括处理的基本原理和处理流程，讨论了图变换操作的SEOL描述。

This paper present the meaning of semantic equivalence and Herbrand equivalence based upon denotational sematics with concrete programming language.Herbrand equivalence is weaker than Semantic equivalence, it has much wider utility.

从指称语义出发，结合具体语言，用形式化的方法讨论了语义等价和H-等价。H-等价的判定条件相对来说更容易得到满足，具有更广泛的可用性。

The traditional query tree optimization methods,parallel database optimization methods based on left linear trees and right linear trees,bushy trees,and operation of the forest,have their own pros and cons,they have been more in-depth and maturity of the study.The query optimization method based on multiple weighted tree has studied its model of parallel query plan,its complexity model of parallel query plan and query optimization algorithms.The semantic query method transforms an inquiry into one or several semantic equivalence inquiries then has to find and implement a strategy to achieve a better query.Agent-based parallel database query optimization using Multi-Agent technology to automatically search the integrity constraint conditions which are related to the determined query,there for,the efficiency between several relations' joins has been greatly improved.The parallel optimization algorithm,based on genetic algorithm which is suitable for multi-joins of cluster environment,has deeply studied the relations storage options,multi-joins query optimization and query processing and other key technologies based on cluster parallel database.

传统的查询树优化方法，即基于左线性树、右线性树、浓密树、操作森林的并行数据库查询优化方法，各有优劣，对其的研究比较深入、成熟；基于多重加权树的查询优化方法，研究了其并行查询计划模型、并行查询计划的复杂性模型和查询优化算法；语义查询优化方法将一个查询变换成一个或数个语义等价的查询，进而寻找并执行这些等价查询中具有较好实现策略的一个；基于Agent的并行数据库查询优化采用Multi-Agent技术自动查找与给定查询有关的完整性约束条件，使得多个关系间连接操作的效率得到很大的提高；基于遗传算法的并行优化算法，深入研究了基于机群并行数据库中关系存储的选择、多连接查询优化和查询处理等关键技术。
