Electronic mail (Email) system has become a popular method of communication in sharing and growing the knowledge. Selected documents that are shared through email attachments will be downloaded to the personal storage of the receivers. In order to ease the searching of the retrieved files, a basic taxonomy (classification in hierarchical structure) has been used as a common method to organize the storage directories. However, the directory classification need to be improved because by referring to a directory's name only, it is not enough to briefly understand the content of the files. This paper proposes a mind map of tags concept to be an additional element to enhance the documents classification and retrieval. The mind map is applied as a classification widget on a desktop that represents links of documents in the respective cloud of tags. The method and the proposed framework are discussed. © 2013 Springer Science+Business Media.
