Retrospective source attribution for source-oriented sampling

Boosting in Textual Source Attribution

Poster: Source Code Authorship Attribution

As information becomes widely available and easily accessible through the Internet and other sources, the trend of plagiarism has been increasing. Plagiarism and copyright infringement are issues that come up in both academic and corporate environments. We need author classification techniques to inhibit such unethical violations. Source code is also intellectual property and reflects individua...

Using Temporal Sampling to Improve Attribution of Source Populations for Invasive Species

Numerous studies have applied genetic tools to the identification of source populations and transport pathways for invasive species. However, there are many gaps in the knowledge obtained from such studies because comprehensive and meaningful spatial sampling to meet these goals is difficult to achieve. Sampling populations as they arrive at the border should fill the gaps in source population ...

Pitch Continuity and Speech Source Attribution

Two experiments showed that continuity of the pitch contour is an important perceptual indicator that a formant pattern comes from a single speech source. Subjects listened to repeatedly played formant patterns that changed smoothly between two vowels. When the pitch was a monotone, these patterns were heard as containing semivowels and liquid consonants; but when a discontinuous, steplike pitc...

Source Code Authorship Attribution using n-grams

Plagiarism and copyright infringement are major problems in academic and corporate environments. Existing solutions for detecting infringements in structured text such as source code are restricted to textual similarity comparisons of two pieces of work. In this paper, we examine authorship attribution as a means for tackling plagiarism detection. Given several samples of work from several auth...
