The invention relates to the field of resource description framework graphic data partition, and aims at achieving partition of a large-scale RDF graph based on a lexeme and achieving performance of storing RDF graphic data in a distributed mode and improving data query processing. The RDF graphical partition method based on the lexeme comprises the steps of 1, obtaining a class C to which a subject s belongs; 2, generating direct classes of s; 3, generating an RDF mode graph GS corresponding to the RDF graph G; 4, calculating a ratio; 5, calculating a cardinal number factor; 6, conducting assignment on an initial rank values; 7, setting an iteration time; 8, choosing first k direct classes according to the rank values; 9, searching neighbor direct classes C' in sequence; 10, repeating the step 8 and the steps 9 until all the direct classes in top-k are partitioned; 11, conducting postprocessing. The RDF graphical partition method based on the lexeme is mainly applicable to data partition situations. 本发明涉及资源描
