Along with the exponential growth on markets of mobile apps, comes the serious public concern about the security and privacy issues. User comments serve as a valuable source of information for evaluating a mobile app, for both new users and developers. However, for the purpose of evaluation on the security/privacy aspects of an app, user comments are not always directly useful. Most of the comments are about issues like functionality, missing feature or just pure emotional expression. Therefore, further efforts are required in order to identify those Comments with Security/Privacy Issues (CSPI) for future evaluation.
