Six Categories of Amazon Product Reviews Loader¶
Use pip to install this package.
$ pip install --upgrade rgmining-amazon-dataset
Note that this installation will download a big data file from the original web site.
This package provides module
amazon and this module provides function
amazon.load(). The function
load takes a graph object which implements the graph interface defined in Review Graph Mining project. The funciton
load also takes an optional argument, a list of categories. If this argument is given, only reviews for products which belong to the given categories will be loaded.
For example, the following code constructs a graph object provides the FRAUDAR algorithm, loads the Six Categories of Amazon Product Reviews dataset, runs the algorithm, and then outputs names of anomalous reviewers. Since this dataset consists of huge reviews, loading may take long time.
import fraudar import amazon # Construct a graph and load the dataset. graph = fraudar.ReviewGraph() amazon.load(graph) # Run the analyzing algorithm. graph.update() # Print names of reviewers who are judged as anomalous. for r in graph.reviewers: if r.anomalous_score == 1: print r.name # The number of reviewers the dataset has: -> 634295. len(graph.reviewers) # The number of reviewers judged as anomalous: -> 91. len([r for r in graph.reviewers if r.anomalous_score == 1])
Note that you may need to install the FRAUDAR algorithm for the Review Mining Project by
pip install rgmining-fraudar
