FOCUS Datasets

This directory contains the raw JAR files and the meta-data of the four datasets used in the paper:

  • SH_L: 610 Java projects randomly selected and retrieved from GitHub via the Software Heritage archive
  • SH_S: the 200 smallest (in size) Java projects extracted from SHL
  • MV_L: 3,600 JAR files randomly selected and retrieved from the Maven Central repository
  • MV_S: 1,600 JAR files extracted from MVL: for every project, only one version is kepy

We also include the results obtained with PAM using the SHS dataset in the PAM directory.

Meta-data

Naturally, it is not possible to store in this repository the source code of every GitHub project we analyzed. Instead, the four datasets MVL, MVS, SHL, and SHS are organized as follows:

  • Every dataset contains a file List.txt which points to the meta-data extracted from every project it contains (e.g. 200 projects in SH_S/List.txt)
  • Each of these files (e.g. SH_S/2e7aef2f64abd5997e1f2eb5960ea3cf1c072226.txt) contains the list of method invocations made from every method declaration in the project:
    • For instance, the line org/appfuse/webapp/components/MenuItem/getUrl()#java/lang/String/startsWith(java.lang.String) specifies that the method getUrl() in the class org.appfuse.webapp.components.MenuItem invokes the method startsWith(String) of class java.lang.String
  • These meta-data files are produced using the tools contained in FocusRascal
