ca.pfv.spmf.tools.other_dataset_tools.FixTransactionDatabaseTool

public class FixTransactionDatabaseTool
extends java.lang.Object

This tool allows to fix some common problems in a transaction database file in SPMF format. In particular: (1) the tool removes items that appears more than once in a transaction. (2) it sort transactions according to the lexicographical ordering. The reason for performing this is that many itemset and association rule mining algorithms assumes that items cannot appear more than once in a transaction and that transactions are sorted.
