Label Propagation

**Table 1** **parameters** parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
coveragence	No	Convergence	Double	A real number between 0 and 1 (excluding 0 and 1)	0.00001
max_iterations	No	Maximum iterations	Integer	1 to 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.	-

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