We describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different e-mail topics. An extended set of e-mail document features(More)
This paper describes an investigation of authorship gender attribution mining from e-mail text documents. We used an extended set of predominantly topic content-free e-mail document features such as style markers, structural characteristics and gender-preferential language features together with a Support Vector Machine learning algorithm. Experiments using(More)
The bacteriophage population is large, dynamic, ancient, and genetically diverse. Limited genomic information shows that phage genomes are mosaic, and the genetic architecture of phage populations remains ill-defined. To understand the population structure of phages infecting a single host strain, we isolated, sequenced, and compared 627 phages of(More)
We describe an investigation of authorship gender and language background cohort attribution mining from e-mail text documents. We used an extended set of predominantly topic content-free e-mail document features such as style markers, structural characteristics and gender-preferential language features together with a Support Vector Machine learning(More)
Information security officers of large organisations have the responsibility, inter alia, to advise senior management on the current level of organisational risk and to overview the operation of effective security systems within the organisation. Current developments in risk analysis methodologies and system security certification, e.g. ITSEC, can provide(More)
Intrusion detection techniques have appeared to inspect all of the inbound and outbound network activities, and to identify suspicious patterns that indicate an attack that might compromise an information system. However, related information can be collected so as to supply evidence in criminal and civil legal proceedings. Several works have been carried(More)
OBJECTIVES To investigate risk factors for seizure onset in Rett syndrome. STUDY DESIGN Information on presence and age at onset of seizures, perinatal and developmental history, and genetic status was abstracted on 275 cases in the Australian Rett Syndrome Database. Cox and Weibull regression were used to investigate and provide a model for predicting(More)
The overlap between autism and Rett syndrome clinical features has led to many cases of Rett syndrome being initially diagnosed with infantile autism or as having some autistic features. Both conditions seriously disrupt social and language development and are often accompanied by repetitive, nonpurposeful stereotypic hand movements. The aims of this study(More)
