    • A method and system are disclosed for indexing a set of statements, such as RDF statements, that are described in accordance with a specified ontology. The method comprises the steps of defining a set of indexing rules, and using these indexing rules to examine the statements to identify selected ones of the statements and to generate one or more indices from said selected ones of the statements. In a preferred embodiment, the rules match certain predicates of RDF statements to certain indices. Also, preferably, an RDF storage system may be configured with said set of indexing rules. When RDF statements are added to the RDF storage system, each statement is examined by the indexing subsystem. If the predicate of a statement matches one of the predicates of said set of indexing rules, that rule is applied to the statement.
    • 公开了一种用于索引根据指定本体描述的一组语句(例如RDF语句)的方法和系统。 该方法包括以下步骤:定义一组索引规则,并使用这些索引规则来检查语句以识别所选择的语句中的一个,并从所述选择的语句生成一个或多个索引。 在优选实施例中,规则将RDF语句的某些谓词与某些索引相匹配。 此外,优选地,RDF存储系统可以配置有所述索引规则集合。 当将RDF语句添加到RDF存储系统时,每个语句都由索引子系统检查。 如果语句的谓词与所述索引规则集的谓词之一匹配,则该规则将应用于该语句。
