Knowledge graph platform, query method and device thereof and electronic equipment

The embodiment of the invention discloses a knowledge graph platform, a query method and device thereof and electronic equipment. The knowledge graph platform comprises a graph visualization module which is used for performing graph rendering through a professional graph visualization framework and a general visualization library; the graph application modeling module is used for carrying out user-defined modeling by utilizing a plurality of general operators; the graph calculation module is used for submitting a spark task to a big data platform for model calculation, and storing an obtained mining result to a data warehouse; and the graph storage module is used for storing entities, relational data and mining results. The knowledge graph formed by performing knowledge mining through a unified standard knowledge graph platform can enable the constructed knowledge graph to have standardization and systematization, and remote submission is performed by multiplexing a big data platform Spark computing component
