Analyzing Text in Software Projects [chapter]

Stefan Wagner, Daniel Méndez Fernández
2015 The Art and Science of Analyzing Software Data  
Most of the data produced in software projects is of textual nature: source code, specifications, or documentations.  ...  We illustrate the introduced methods via a running example and conclude by presenting two industrial studies.  ...  The research on text analytics is still very active and we expect to see many more innovations that we will be able to exploit also for analysing textual project data from software projects.  ...
