中文简介: | RDF图包含高度复杂的数据,无论是从结构角度还是从语义角度来看。这使得它们很难被发现和学习,并阻碍了它们的可用性。图商形式为总结图提供了一个优雅的基础。简而言之,图商指定了一种将某些图节点视为彼此等价的方式,并通过基于这种等价的等价类来表示图。我将介绍我上一个团队在过去几年中所做的工作,即语义丰富的RDF图的商摘要。特别是,我将介绍一组特别适合RDF图异构结构的摘要,并讨论摘要和饱和与RDF模式规则相互作用的新结果。 |
课程简介: | RDF graphs comprise highly complex data, both from a structural and from a semantic perspective. This makes them hard to discover and learn, and hinders their usability. An elegant basis for summarizing graphs is provided by the graph quotient formalism. In a nutshell, a graph quotient specifies a way to view some graph nodes as equivalent to each other, and represents a graph through its equivalence classes based on this equivalence. I will present work carried in my last team over the last few years, on quotient summarization of semantic-rich RDF graph. In particular, I will introduce a set of summaries particularly suited for the heterogeneous structure of RDF graphs, and discuss novel results at the interplay of summarization and saturation with RDF Schema rules |
