In the previous HowNet system, there was no such database. In the past, HowNet system automatically excluded sentences, directories and references, not counting text duplication, and judged the segmentation and citation of articles according to directories and references. Thank you for your participation in the test. Supports the detection of content in text, formula, table and picture formats.

A "source code library" has been added to the latest version report of HowNet duplicate checking system version 5.3, which supports the detection and comparison of cpp, java, py and other source codes. The source code library is a comparison library added at the end of 20 19 and 10 in the latest version 5.3. After adding the "source code library", the code in the paper needs to be checked again. It can be said that the upgraded HowNet system has a wider scope of duplicate checking.
