示例2: stage

/**
 * The Main of the MFIBlocking Algorithm
 * @param args
 * The parameters are as follows:
	1. Path to the lexicon file created in the previous stage (out parameter 6).
	2. The dataset of item ids created in the previous stage (out parameter 2).
	3. The set of min_th parameters you would like the algorithm to run on. This parameter is optional and 0 can be provided as the only parameter effectively eliminating the threshold.
	4. Path to the generated match file (out parameter 3).
	5. path to the debug file containing the items themselves (out parameter 7)
	6. The set of min supports to use.
	7. Must be set to MFI
	8. The set of p parameters to use as the Neighberhood Growth constraints.
