Dynamic Thresholding Mechanisms for IR-Based Filtering in Efficient Source Code Plagiarism Detection [article]

Oscar Karnalim, Lisan Sulistiani
2018 arXiv   pre-print
To solve time inefficiency issue, only potential pairs are compared in string-matching-based source code plagiarism detection; wherein potentiality is defined through a fast-yet-order-insensitive similarity  ...  This paper proposes two thresholding mechanisms---namely range-based and pair-count-based mechanism---that dynamically tune the threshold based on the distribution of resulted similarity degrees.  ...  P CM (in) = in * total pairs (2) For our case study, both thresholding mechanisms will be applied on an efficiency-oriented hybrid source code plagiarism detection, which works in fourfold (see Fig. 1  ...

Spatio-textual similarity joins

Panagiotis Bouros, Shen Ge, Nikos Mamoulis
2012 Proceedings of the VLDB Endowment  
Despite the importance of this operation, there is very little previous work that studies its efficient evaluation and in fact under a different definition; only the best match for each object is identified  ...  In this paper, we combine ideas from state-of-the-art spatial distance join and set similarity join methods and propose efficient algorithms that take into account both spatial and textual constraints.  ...  The main application of set-similarity joins is near-duplicate object detection [14] (e.g., identify plagiarism, record linkage in data integration, duplicate data cleansing, etc.).  ...
