Embodiment Construction
[0030]Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.
[0031] The present invention comprises the following stages during concrete implementation:
[0032] Step 1, preprocessing the probability subgraph. From the input probabilistic network (probability graph), all probability subgraphs of a given node size are identified without repetition or omission. Using the implementation structure based on the Spark parallel framework, the obtained probability subgraphs are stored in the HDFS file system, and then all probability subgraph files are loaded into ...
