Examples
- The thesis elucidates the content index & structure index for xml documents and gives the harmony combining method between the content index and structure index
本文研究了对xml文档进行内容索引和结构索引的方法，尤其是内容索引和结构索引的有机结合机制。 - This paper refers to the indexing technologies of b ~ + - tree in dbms , and combine it with the sparse numbering schema , and proposes a new indexed structure ? b ~ + - tree structural index . it is very important for the optimization of join operation and element location in xml query
本文将关系数据库中b树索引技术与sparsenumberingschema相结合，提出了一种新的xml文件索引结构? ? b ~ +树结构索引，它对xml查询中连接操作和元素定位操作的优化有着重要作用。 - W2x have several merits : to begin with , it can retrieve chinese xml document ; moreover , it can process both text - rich xml data and data - rich xml data ; besides , it adopts efficient indexing algorithm and query processing algorithm introduced by this dissertation , which enables w2x to manage large - scale xml data
W2x是一个中文xml信息检索系统，它可以管理富含文本信息的xml数据和富含值信息的xml数据，并采用了高效的xml结构索引算法和查询处理算法，可以完成对大规模xml数据的检索。 - The thesis uses four index files to complete the content index & structure index : chinese character index , english string index , element index and attribute index . the thesis first gives the pre - post node labeling method , then puts forward the tree - adjacent table , transforms the dom - tree into tree - adjacent table , in the last creates element index and attribute index from tree - adjacent table
针对结构索引的建造，本文首先阐明了前序一后序节点标号法，然后提出了树邻接表的概念，并给出了把dom树转换为树邻接表的办法；最后对树邻接表进行前序-后序遍历，得到每个节点的标号，并组装成结构索引文件。 - To manage large - scale xml documents with complicated structure , this dissertation focus on the efficient structural indexing algorithm for xml data , result size estimation problem for xml structure based query optimization , result relevance ranking algorithm , and infrastructure for xml query processing for both text - rich and data - rich xml documents . to address the aforementioned issues , this dissertation makes the following contributions . first , it investigates the drawbacks of existing indexing algorithm for xml data , and propose a dynamic indexing algorithm for xml data based on d - bisimilarity , difx
为满足结构复杂、大规模的xml数据管理需要，本文深入研究了xml信息检索系统中的结构索引算法设计和结构化查询优化中的查询代价估计问题，以及查询结果和查询条件间的相关度算法，主要取得了4个方面的成果：第一，分析了已有的xml数据索引算法中存在的问题，提出了一种高效的动态xml结构索引算法difx ，它采用动态后向结构相似性( d - bisimilarity )的概念，可以根据实际查询需求以及索引最优化的要求动态决定索引中保存的结构信息。
