   ABSTRACT     = {Identifiers represent an important source of information 
      for programmers understanding and maintaining a system. 
      Self-documenting identifiers reduce the time and effort necessary to 
      obtain the level of understanding appropriate for the task at hand. 
      While the role of the lexicon in program comprehension has long been 
      recognized, only a few works have studied the quality and enhancement 
      of the identifiers and no works have studied the evolution of the 
      lexicon. In this paper, we characterize the evolution of program 
      identifiers in terms of stability metrics and occurrences of 
      renaming. We assess whether an evolution process similar to the one 
      occurring for the program structure exists for identifiers. We report 
      data and results about the evolution of three large systems, for 
      which several releases are available. We have found evidence that the 
      evolution of the lexicon is more limited and constrained than the 
      evolution of the structure. We argue that the different evolution 
      results from several factors including the lack of advanced tool 
      support for lexicon construction, documentation, and evolution. 
      Finally, we suggest the existence of rules on the co-evolution of 
      structure and lexicon of software systems.}
