Analyze command usage¶

The basic usage of this command is

\$ analyze <dataset-specifier> <dataset-parameters> <method-specifier> <method-parameters> <options>

The dataset-specifier and datasset-parameters are the same parameters described in the dataset command explanation.

The method-specifier is a name of installed method. You can see available method names by analyze -h.

method-parameters are optional arguments specified with --method-param flag. The --method-param flag takes a string which connecting key and value with a single =, and can be given multi-times.

You can find what kinds of parameter keys are defined in the method you want to run from documents of the constructor of the review graph object defined in the method.

For example, Fraud Eagle takes one parameter epsilon and you can give a value by --method-param epsilon=0.25.

analyze also takes three options:

• --threshold: threshold to distinguish an update is negligible (Default: $$10^{-5}$$),
• --loop: the maximum number of iterations (Default: 20),
• --output: file path to store results (Default: stdout).

Most of methods, the Review Graph Mining project provides, are loop based algorithms, which iterate some procedure until the update will be negligible. The --threshold flag sets a threshold and if an update is smaller than or equal to the threshold, it will be decided as negligible and the iteration will be ended.

On the other hand, some methods with some datasets won’t converge or even if they will converge but it takes lots of time. The --loop flag sets the maximum number of iterations to stop algorithms.
