Recently, the network environment in classroom has been much improved. However, the facilities may promote the imprudent plagiarism of the other's answer in online report submission. We are developing the detection tool for report plagiarism based on similarity. We adopt two kinds of approach for similarity judgment. The one is text base by minimum operations as editorial distance. The another is binary base by file compression ratio as information distance. We prepare some preprocess methods like morphological analysis and removing redundant information. We aim to realize adequate judgment precision and cost performance. The tool works as an application and is embedded as a plug-in module in various educational support systems. It uses not only for exposure of the fraudulent activity by a teacher but also for the warnings at the time of students' uploading files. Especially, we apply the tool to C programs by source codes and assemble codes. We revise the GUI as an application and the external interface as a plug-in module. We adopt document oriented DB and introduce distributed processing for efficient calculation. |
