The example files in this directory demonstrate how to use the options -b, -f, and -r and the optional item appearances file. In the file test1.tab transactions are separated by newline characters and the items of a transaction are separated by spaces. This is the standard input format and hence the file can be processed directly: apriori test1.tab test1.rul In the file test2.tab the same transactions can be found, but several different field separators are used. This file can be processed with: apriori -f ",.;:" -l test3.tab test3.rul The files test3.tab and test4.tab are in formats that cannot be processed directly with the apriori program, but which may be common. In the file test3.tab each line contains a transaction identifier and an item, separated by a space. This file can be converted into the standard input format with the script tid2set, i.e., with tid2set test3.tab x.tab In the file test4.tab the first line states the item names and the following lines contain flags T (true) and F (false) depending on whether the item is contained in the transaction represented by the line or not. This format can be converted into the standard input format with the script flg2set, i.e., with flg2set test4.tab x.tab In the file test5.tab there is one item per line and transactions are separated by blank lines. This format can be converted into the standard input format with the script row2set, i.e., with row2set test5.tab x.tab The file test.app demonstrates the use of item appearance indicators. The first line of this file ('body') states that any item not explicitly mentioned in this file may appear only in the body of a rule. The second line says that item 2 may appear only in the head of a rule. Hence, by processing the file test1.tab with apriori test1.tab test.rul test.app only rules with item 2 in the head are generated. Note that any input may also be read from standard input and any output may be sent to standard output, simply by specifying a '-' or an empty string "" instead of a filename. For example apriori test1.tab - writes the rules directly to the terminal. They may be piped to any other program, since all other messages of the apriori program are written to standard error. Enjoy, Christian Borgelt
