| Research Abstract |
In this research, we tackle the problem of detecting document infringement, which is considered as a severe problem owing to the convenience of Internet. Typical information retrieval methods, stopword-based methods and fingerprinting methods are commonly used to detect infringement by using sequences of words as they appear in the document. As such, they fail to detect infringement when an author reconstructs a source document by re-ordering and re-combining phrases. Because graph structure fits for representing relationships between entities, we propose a novel infringement detection method, in which we use graphs to represent documents by modeling grammatical relationships between words. Experimental results show that our proposed method outperforms two n-gram methods and increases recall values by 10%.
