INVocD: Identifier name vocabulary dataset

INVocD is a database of the identifier name declarations and vocabulary found in 60 FLOSS Java projects where the source code structure is recorded and the identifier name vocabulary is made directly available, offering advantages for identifier name research over conventional source code models. The database has been used to support a range of research projects from identifier name analysis to concept location, and provides many opportunities to researchers.
