  • Described as follows:
  • Design a paper duplication checking algorithm, give an original document and a plagiarized version of the paper with additions, deletions and modifications on the original document, and output the duplication rate in the answer file.
  • Example of the original text: Today is Sunday, the weather is fine, and I am going to the movies tonight.
  • Example of plagiarism: Today is Sunday, the weather is fine, and I am going to the movies in the evening.
  • It is required that the input and output use file input and output, and the specifications are as follows:
  • Given from command line arguments: the absolute path to the file of the original paper.
  • Given from the command line arguments: the absolute path to the file of the plagiarized version of the paper.
  • Given from command line arguments: Absolute path to the output answer file.

• Implementation principle: Calculate the text similarity by the cosine similarity algorithm. If the value is closer to 1, the similarity is greater, otherwise the similarity is smaller.

  • The picture is as follows:
    

• Part of the code is as follows:
