基于AllegroGraph的空间数据语义查询研究

摘要

In the Semantic Web environment, the expression of spatial data semantics for AllegroGraph RDF databse is introduced, the index mechanism and elaborated, and its good performance in handling semantic query technology of AllegroGraph analyzed and query of large spatial dataset demonstrated through an experiment.%在语义网环境下，对AllegroGraph RDF数据库的空间数据语义表达方式进行了介绍，分析、阐述了其索引机制和查询技术，并通过实验，验证了其处理大规模空间数据语义查询的良好性能．
