    摘要: The present invention provides a ViST (or “virtual suffix tree”), which is a novel index structure for searching XML documents. By representing both XML documents and XML queries in structure-encoded sequences, it is shown that querying XML data is equivalent to finding (non-contiguous) subsequence matches. A variety of XML queries, including those with branches, or wild-cards (‘*’ and ‘//’), can be expressed by structure-encoded sequences. Unlike index methods that disassemble a query into multiple sub-queries, and then join the results of these sub-queries to provide the final answers, ViST uses tree structures as the basic unit of query to avoid expensive join operations. Furthermore, ViST provides a unified index on both content and structure of the XML documents, hence it has a performance advantage over methods indexing either just content or structure. ViST supports dynamic index update, and it relies solely on B+Trees without using any specialized data structures that are not well supported by common database management systems (hereinafter referred to as “DBMSs”).

    摘要翻译: 本发明提供了一种ViST(或“虚拟后缀树”),其是用于搜索XML文档的新型索引结构。 通过在结构编码序列中同时表示XML文档和XML查询,显示查询XML数据等同于查找(非连续)子序列匹配。 各种XML查询(包括具有分支的查询)或通配符('*'和'//')可以由结构编码的序列表示。 不同于将查询反汇编成多个子查询的索引方法,然后加入这些子查询的结果以提供最终答案,ViST使用树结构作为查询的基本单位,以避免昂贵的连接操作。 此外,ViST为XML文档的内容和结构提供了一个统一的索引,因此与仅通过内容或结构索引方法相比,它具有性能优势。 ViST支持动态索引更新,它仅仅依赖于B< +>树,而不使用通用数据库管理系统(以下简称“DBMS”)不能很好支持的任何专门的数据结构。

    摘要: A method which identifies different types of substructures within a graph and encodes them using techniques suitable to the characteristics of each of them. The method is embodied by an efficient two-phase algorithm, where the first phase identifies and encodes strongly connected components as well as tree substructures, and the second phase encodes the remaining reachability relationships by compressing dense rectangular submatrices in the transitive closure matrix.

    摘要: Sequence-based XML indexing aims at avoiding expensive join operations in query processing. It transforms structured XML data into sequences so that a structured query can be answered holistically through subsequence matching. Herein, there is addresed the problem of query equivalence with respect to this transformation, and thereis introduced a performance-oriented principle for sequencing tree structures. With query equivalence, XML queries can be performed through subsequence matching without join operations, post-processing, or other special handling for problems such as false alarms. There is identified a class of sequencing methods for this purpose, and there is presented a novel subsequence matching algorithm that observe query equivalence. Also introduced is a performance-oriented principle to guide the sequencing of tree structures. For any given XML dataset, the principle finds an optimal sequencing strategy according to its schema and its data distribution; there is thus presented herein a novel method that realizes this principle.

    摘要: Disclosed are a method, information processing system, and computer readable medium for processing queries. The method includes receiving a data query for a set of hierarchical markup documents. At least one query path expression is extracted from the data query. The query path is processed against at least one shared hierarchical markup document in a plurality of shared hierarchical markup documents. The plurality of shared hierarchical documents is associated with the set of hierarchical markup documents. In response to the shared hierarchical markup document completely matching the query path expression, a query result for the data query is generated. The query result is based on the processing of the query path expression against at least one of the shared hierarchical markup document and the difference hierarchical markup document.

    摘要: A method for supporting semantic matching queries in a database management system (DBMS) by extracting and storing the transitive/subsumption relationships from a given ontology data in a DBMS with native XML support. These transitive relationships are transformed into a set of XML documents that are natural mappings of the hierarchical structure of the transitive relationships. A table function construct expresses semantic matching queries in a declarative manner. The semantic matching queried are automatically rewritten or translated into standard SQL/XML search operators such as XQuery, XPath and XMLExists, and executed by the SQL/XML DBMS on the given instance data and the extracted transitive relationships data.
