    • A method and device for optimizing queries over a vertically stored database. Items in the database are partitioned into several partitions each having a partition signature. The method includes decomposing a first query received from a user into multiple first subqueries; generating a signature for each first subquery in a way corresponding to the way of generating the partition signature; comparing the signature of each first subquery with partition signatures of all partitions respectively to obtain all partitions matching the first subquery; rewriting a second subquery translated from the first subquery based on the matching partitions to obtain a rewritten second subquery; and composing rewritten second subqueries for all first subqueries to form a second query so that queries are executed over the database using the second query.
    • 一种用于通过垂直存储的数据库优化查询的方法和设备。 数据库中的项目被分成几个具有分区签名的分区。 该方法包括将从用户接收的第一查询分解成多个第一子查询; 以与生成分区签名的方式相对应的方式为每个第一子查询生成签名; 将每个第一子查询的签名分别与所有分区的分区签名进行比较,以获得与第一子查询匹配的所有分区; 基于匹配分区重写从第一子查询翻译的第二子查询,以获得重写的第二子查询; 并为所有第一个子查询组合重写的第二个子查询以形成第二个查询,以便使用第二个查询在数据库上执行查询。

    • Path-based ranking of unvisited Web pages for WWW crawling is provided, via identifying all the paths beginning with a “seed” URL and leading to visited relevant web pages as “good-path set”, and for each unvisited web page, identifying the paths beginning from the “seed” URL leading to it as “partial-path set”; classifying all the visited web pages and labeling each web Page with the labels of a class or classes it belongs to; training a statistic model for generalizing the common patterns among all ones of “good-path set”; and evaluating the “partial-path set” with the statistic model and ranking the unvisited web pages with the evaluation results.
    • 通过识别从“种子”URL开始的所有路径,并将访问过的相关网页导向为“良好路径集”,并为每个未访问的网页标识,以提供用于WWW抓取的未访问网页的基于路径的排名 从“种子”URL开始的路径导致它作为“部分路径集”; 对所有访问的网页进行分类,并使用所属类别的标签将每个网页标注; 培养统一模式,推广“好路径”的共同模式; 并用统计模型评估“部分路径集”,并通过评估结果对未访问的网页进行排序。

    • The present invention provides a system and method for automatically refining ontology within a specific context. The system comprises: a rich context extractor for discovering a semantics relationship conflict existing between an original ontology schema and application data; and an ontology schema and mapping refiner for refining the original ontology schema based on the semantics relationship conflict discovered by the rich context extractor, and creating a new mapping between the refined ontology schema and a data schema of the application data. According to the invention, users can save a lot of work of manual refinement, since the ontology schema is automatically refined based on contexts in the application data.
    • 本发明提供了一种用于在特定上下文内自动优化本体的系统和方法。 该系统包括:用于发现原始本体模式和应用数据之间存在的语义关系冲突的丰富上下文提取器; 以及本体模式和映射精简器,用于根据丰富上下文提取器发现的语义关系冲突来完善原始本体模式,并在精简本体模式和应用程序数据的数据模式之间创建新的映射。 根据本发明,用户可以节省大量的手工细化工作,因为基于应用数据中的上下文自动地改进了本体模式。
