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.

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。

With the development of Semantic Web, research of semantic search has already been a hot spot.

随着语义网技术的发展，语义检索的研究已成为热点领域。

Therefore, on the basis of objective description of corpus example, this paper study and analyze the condition of "free form" and "bound form" of the verbal phrases such as "V + Particle + N"、"V+ complement"(including:"V+ trend complement","V+ result complement","V+ extent complement" and "V+ action-measure complement )、"V TO V"、"V+ adverb+ V"、"V of V "and "V+ D".At the same time, from the semantic and pragmatic perspective this paper discuss the conditions and causes from "bound form" to "free form",concluding that particle dynamics、exclamation at the end of the sentence、adverb and follow—up of the language and so on can act as the conditions from the bound verbal phrase to the free verbal phrase. The main reason for these conditions is rich in the amount of the sentence, making semantic self—contained; Finally, this paper simply describes the theoretical and practical significance of the phenomena of "free form" and "bound form in the aspect of verbal phrase; at he conclusion of the article, the author of the text further sum up the content and coverage and raise her own views of the text of underdevelopment and the questions yet continuing to study.

因此，本文接着在语料例证的客观描述基础上，针对"v+动态助词+N"、"V+补语"(包括："V+趋向补语"、"V+结果补语"、"V+程度补语"、V+动量补语)、、"V来V去"、"副词+V"、"V的V"、"V+D的"等动词性短语的"粘着"和"自由"的情况做了探讨分析，并且从语义和语用两个角度探讨了"粘着"向"自由"转化的条件及原因，认为动态助词、句末语气词、副词、后续语段等等都可以充当粘着的动词性短语向自由的动词性短语转化的条件，其主要原因则是这些条件丰富了句子的信息量，使得语义自足；最后，文章简要地论述了研究动词性短语的"自由"和"粘着"现象的理论意义和实践意义；在文章的结语部分，作者就文中所论述的角度和涵盖的内容做了进一步的总结，并对文中存在的不足和有待于继续研究的问题提出了自己的看法。

Latent semantic index LSIis a new algebraic model for information retrieval, which maps documents and queries vectors into a lower dimensional space by singular value decomposition, so that the inherent vagueness associated with a retrieval process based on keyword sets is considerably reduced and semantic association among the documents is highlighted consequently.

隐含语义索引是一种新型的信息检索模型，它通过奇异值分解，将词向量和文档向量投影到一个低雏空间，消减了词和文档之间的语义模糊度，使得文档之间的语义关系更为明晰。

Research on Korean adverbs of degree made before is mainly focused on category, subordinate and classification, with little notice on syntactic and semantic features of some adverbs, especially semantic difference, co-occurrence, syntactic constraints of synonyms.

前人对韩国语程度副词的研究焦点大部分集中在程度副词的范畴、下位分类、程度的等级化等方面，而对个别副词的句法、语义特性研究很不充分，尤其是研究类义词的语义差异、共现制约、句法条件等方面的研究更是微乎其微。

On this basis, taking into account the diversity of user interest as well as the synonymity and semantic correlation of word expression, the paper further proposed a method for user multi-interest modeling based on semantic similar network, which uses SSN to expand user feature words with its synonyms and correlative words on the knowledge level, and divides user interest into multi-categories, thus to establish a multi-interest user model.

在此基础上，考虑到用户兴趣的多样性及词语表达的同义性和语义相关性问题，本文进一步提出一种基于语义相似网络的用户多兴趣建模方法，该方法使用SSN对用户兴趣特征词进行知识层面上的扩展，联想出同义词和相关词，并将用户兴趣细分为多个类别，建立起多兴趣的用户模型。
