  Most of open-source software systems become available on the internet today.
Thus, we need automatic methods to label software code. Software code can be
labeled with a set of keywords. These keywords in this paper referred as
software labels. The goal of this paper is to provide a quick view of the
software code vocabulary. This paper proposes an automatic approach to document
the object-oriented software by labeling its code. The approach exploits all
software identifiers to label software code. The paper presents the results of
study conducted on the ArgoUML and drawing shapes case studies. Results showed
that all code labels were correctly identified.
