Disclosed is an online serviceable system for searching for a plagiarism document. The system for searching for a plagiarism document includes: a memory on which at least one program is loaded; and at least one processor, wherein the at least one processor, under a control of the program, processes: a preprocessing step for segmenting each of original documents and a document to be examined, in units of words, and storing, in a database, the segmented words together with representative synonyms thereof which are discovered in a synonym dictionary; a step for selecting, from the original documents, first documents which are determined to be similar to the document to be examined on the basis of the Jaccard coefficient-based similarity; and a step for selecting, from the first documents, second documents which are determined to be similar to the document to be examined on the basis of the cosine distance-based similarity.
