To go beyond what current provenance systems can capture for natural language text documents, we propose the Lincoln Laboratory Plagiarism for Provenance System (LLPla Ì) as an approach for capturing linguistic provenance. Linguistic provenance infers the origin of text based on its linguistic structure. We take a plagiarism detection approach to this task as identifying similar sections of text is...
Previous provenance models have assumed that there is complete certainty in the provenance rela- tionships. But what if this assumption does not hold? In this work, we propose a probabilistic provenance graph (PPG) model to characterize scenarios where provenance relationships are uncertain. We describe two motivating examples. The first example demon- strates the uncertainty associated with the prove-...
