**Table 1** parameters parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
convergence	No	Convergence	Double	The value is a real number between 0 and 1.	0.00001
max_iterations	No	Maximum iterations	Integer	An integer ranging from 1 to 2147483647. For frontend calls, the range is [1,2000].	1000
initial	No	Name of the property used as the initialization label on a vertex	String	Empty or character string Empty: Each vertex is allocated with a unique initialization label. This method is applicable to scenarios where no vertex label information exists. Character string: The value of the property field corresponding to each vertex is used as the initialization label (the type is string, and the initialization label field is left blank for a vertex with unknown labels). This method is applicable to scenarios where some vertex labels are marked to predict unknown vertex labels. NOTE: If the value of initial is a character string, the number of vertices with initialization labels must be greater than 0 and less than the total number of vertices.	-

NOTE:

For details about algorithm iterations and convergence, see Iterations and Convergence of PageRank.

**Table 2** response_data parameter description
Parameter	Type	Description
community	List	Community corresponding to each vertex. The format is as follows: [{vertexId:communityId},...] where vertexId is of the string type. communityId is of the string type.
