We present semantic sequence kernel (SSK) to detect document plagiarism, which is derived from string kernel (SK) and word sequence kernel (WSK). SSK first finds out semantic sequences in documents, and then it uses a kernel function to calculate their similarity. SK and WSK only calculate the gap b...
