Embodiment Construction
[0076] see figure 1 , the present invention a kind of RDF approximate answer inquiry method based on node context vector space, comprises the following steps:
[0077] S1. Analyze the nodes and edges in the RDF graph, and define the context information of a node; again, traverse all the nodes and edges in the RDF graph, and represent the RDF graph in a low-dimensional continuous vector space. The method of negative sampling improves efficiency. In the generated vector space, RDF node vectors with similar semantics are closely distributed, and the representation of nodes and edges between nodes is the translation operation between vectors;
[0078] S101. The RDF graph is defined as: let ε be a node set, is the set of edges between nodes.
[0079] An RDF triple can be expressed as h , r, e t >, where e h , e t ∈ε, i.e. at the head node e h with tail node e t There is an edge r between, eg , an RDF graph is a finite set of RDF triples.
[0080] S102. RDF node contex...
