Code Smells Dataset (oracles)

This repository contains the datasets, obtained in 3 years, resulting from the Crowdsmelling methodology.
Each file contains the dataset (oracle) of the year or set of years, for the code smells Long Method, God Class, and Feature Envy. The file Exercise-Code smells detection (ESII 2020).pdf describes the exercise used in the validation of code smells, and the file code-classification-statistics.csv shows statistics about the percentages of teams that classified the methods and classes.
