Doc Errors

The 'Doc Error' occurs after a file is uploaded for a plagiarism check in DrillBit. An alert symbol will be displayed in front of the similarity percentage in the Similarity column of the file management overview, indicating that an issue was detected with the document.

Users will also see DocError message when opening the analysis page by clicking on the percentage in the file management overview.

The following are specific reasons for a DocError: 1. Document is Corrupted or Encrypted: The document may be corrupted or encrypted, preventing it from being processed correctly.

  1. Document Contains Excessive Image Formats or Fewer Than 50 Words: The file might include too many images or have fewer than the minimum required 50 words.
  2. Document Contains Hidden Characters or Symbols: Hidden characters or symbols within the document interfere with the analysis process.
  3. Document Contains Small Fonts Between Words: Fonts that are too small to be visible without extreme zoom (beyond 800%) may cause issues.
  4. Document is Illicitly Modified with Alphanumeric Substitutions: The document has been altered using substitutions like replacing '0' with 'O' or '1' with 'l', affecting its integrity.
  5. Document Created by an Unsecured Editor: The document was produced using an unverified or insecure text editor, which may lead to processing errors.
  6. Document Created by an Unsecured PDF Converter: The document was converted using an unsecured PDF converter, resulting in potential issues during processing.
