Social network-oriented hierarchical super-dimensional knowledge graph construction method

The invention belongs to the technical field of knowledge maps, and discloses a social network-oriented hierarchical super-dimensional knowledge graph construction method. Relevant information of commodities in a social network is complex and is difficult to effectively convert by using an existing knowledge graph. The method comprises the following steps: firstly, analyzing composition structures of various types of information in a social network, and defining a corresponding super-dimensional knowledge graph architecture; then extracting specific knowledge related to commodity recommendation, performing concept layering according to the property of the specific knowledge, and establishing association mapping between layers according to the corresponding relation of the specific knowledge; organizing the obtained knowledge according to the constructed structure mode to realize the conversion of multiple groups; and finally, by utilizing the obtained social network knowledge graph and combining personal pref
