Abstract: A system (100) for distributed querying of linked semantic webs (110) comprising at least one LOD ontologies index (120) comprising LOD ontologies and metadata relating to said LOD ontologies; at least one concept index (130) comprising concepts and corresponding URIs; at least one relation index (140) comprising relations and corresponding URIs; query interface (160) for entering SPARQL queries; and a distributed query engine (150) in communication with said LOD ontologies index (120), concept index (130) and relations index (140) and adapted to receive queries from said query interface (160); characterised in that said distributed query engine (150) is adapted to: parse and rewrite queries received from said query interface (160) and generate a plurality of sub-queries; identify dependencies within said sub-queries and chunk sub-queries based on ontology; execute sub-queries by sending to relevant source ontology; and merge results obtained from execution of said sub-queries.

Abstract translation: 一种用于分布式查询链接的语义网络（110）的系统（100），包括至少一个LOD本体索引（120），其包含LOD本体和与所述LOD本体有关的元数据; 包括概念和对应的URI的至少一个概念索引（130）; 包括关系和对应的URI的至少一个关系索引（140）; 用于输入SPARQL查询的查询界面（160） 以及与所述LOD本体索引（120），概念索引（130）和关系索引（140）通信并且适于从所述查询接口（160）接收查询的分布式查询引擎（150）; 其特征在于，所述分布式查询引擎（150）适于：解析并重写从所述查询接口（160）接收的查询并生成多个子查询; 基于本体识别所述子查询和块子查询内的依赖关系; 通过发送到相关源本体来执行子查询; 并合并从执行所述子查询获得的结果。
