A solution for Linked Data Mining Challenge 2016. The paper is available in the folder paper, and the supplementary material is in the folder LOD.
The data used for mining are available as Turtle file data.ttl.
A property :has_metric connects album to its metrics.
Every metric is represented as a blank node with a textual :name and numeric :value.
An example below states that album http://dbpedia.org/resource/The_Tight_Connection has 9 reviews on Amazon (:amazon_nusers) with an average review score 4.1 (:amazon_rating). Prefix : corresponds to the namespace https://github.com/jpotoniec/LDMC2016#
<http://dbpedia.org/resource/The_Tight_Connection> :has_metric [ :name "amazon_nusers"; :value "9"^^xsd:double ], [ :name "amazon_rating"; :value "4.1"^^xsd:double ].
For convenience, the same data are available as CSV files.
The mining workflow in directory RapidMiner uses the CSV files.
