Label Propagation (2.1.8)

**Table 1** parameters parameter descriptions
Parameter	Mandatory	Type	Value Range	Description	Default Value
convergence	No	Double	The value is a real number between 0 and 1.	Convergence.	0.00001
max_iterations	No	Integer	Maximum iterations. An integer ranging from 1 to 2147483647. For frontend calls, the range is [1, 2000]. The default value is 1000.	Maximum iterations.	1000
initial	No	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.	Name of the property used as the initialization label on a vertex.	-
weight	No	String	Null or string Null: The default weight and distance of edges are 1. String: The property of the corresponding edge is the weight. If the edge does not have a property, the weight is 1 by default. NOTE: The weight of an edge must be greater than 0.	Weight of an edge.	Null

**Table 2** response_data parameter descriptions
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.
