In this chapter, we briefly overview the relatively new discipline of computer forensics and describe an investigation of forensic authorship attribution or identification undertaken on a corpus of multi-author and multi-topic e-mail documents. We use an extended set of e-mail document features such as structural characteristics and linguistic patterns together with a Support Vector Machine as the learning algorithm. Experiments on a number of e-mail documents generated by different authors on a set of topics gave promising results for both inter- and intratopic author categorisation.
