    • A method for achieving interactive browsing includes steps performed by a computer coupled to a knowledge base and a document database. The knowledge base stores a plurality of terms and information relating to each term, and the document database stores a plurality of documents. The steps include acquiring terms in which a user has interest; extracting information relating to the terms in which the user has interest from the knowledge base in order to display the information in a first display part of a user interface; and extracting documents containing the terms in which the user has interest from the document database in order to display a list of extracted documents in a second display part of the user interface.

    • 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.

    • The invention provides a method and apparatus for obtaining hierarchical information of planar data. The method comprises mapping at least one data item from a same data set in the planar data to at least one node in a tree structure formed by a structured terminology system. The method also comprises obtaining at least one sub tree structure in the tree structure, each of the at least one sub tree structure taking the at least one node as all of its leaf node. The method also comprises selecting a target tree structure from the at least one sub tree structure and obtaining hierarchical information in the target tree structure. An apparatus corresponding to the above method is also provided. With the above method and apparatus, hierarchical information of data items may be obtained from planar organized data to facilitate subsequent and further analysis and management.

    • A dependency graph of rule predicates without strongly connected sub-graph is obtained. The dependency graph indicates the dependency among the rule predicates. An update frequency of node in the dependency graph is calculated, and a query frequency of node in the dependency graph is also calculated. Furthermore, a runtime query cost value and a materialization cost value of the node are calculated based on the query frequency and update frequency. Node to be materialized are determined based on the runtime query cost value and the materialization cost value. A rule predicate corresponding to the node to be materialized is the rule predicate to be materialized. In at least some instances, an exemplary technical effect is that the return time of result of runtime query is saved and the affect by the data update is reduced when a query is performed in relation data reasoning system constructed with rule predicates.
    • 获得没有强连接子图的规则谓词的依赖图。 依赖图表示规则谓词之间的依赖关系。 计算依赖图中节点的更新频率,并计算依赖图中节点的查询频率。 此外,基于查询频率和更新频率来计算节点的运行时查询成本值和实现成本值。 基于运行时查询成本值和实现成本值确定要实现的节点。 与要实现的节点相对应的规则谓词是要实现的规则谓词。 在至少一些情况下,示例性的技术效果是,当在关系数据推理系统构造的规则谓词中执行查询时,保存运行时查询的结果的返回时间,并且减少数据更新的影响。
