اكتشاف سرقة النصوص باستخدام الرسومات البيانية

الملخص EN

In this paper, we discussed a new method to detect the plagiarism based on graph representation; however, Preprocessing for each document is required such as breaking down the document into its constituent sentences.

Segmentation of each sentence into separated terms and stop word removal.

We build the graph by grouping each sentence terms in one node, the resulted nodes are connected to each other based on order of sentence within the document, all nodes in graph are also connected to top level node” Topic Signature “.

Topic signature node is formed by extracting the concepts of each sentence terms and grouping them in such node.

The proposed method achieved a good performance compared by other method that used in the same field.
