dupecheck 0.7.1

Check for duplicate word series between generated text and a dataset

Dupecheck

Analyze your generated text for plagiarizing your dataset

Use this to prevent "Thomas Riker" situations, when generating text with machine learning systems.

At Eclectic Beams, when generating stories from finetuned GPT-2 models, I kept finding nice stories, but whole segments of them were just copied verbatim from the dataset text. I started battling this by using my editor's "find" feature on each line of generated text, or random subsequences against the dataset. It was time-consuming, and caused much eye pain and frustration, each time I'd read a story I liked, only to find out it had large sections copied verbatim.

Time to automate the tedious away.

Dupecheck will search for substrings of given length in a larger text dataset for you. Use this to validate uniqueness before saving generated text, and you'll save yourself a huge headache.

It compares word series without punctuation.

pip install dupecheck

from dupecheck import chunks, sliding_window, sliding_window2

Chunking method

Find word series at least 5 words long in dataset. (Prone to mid-pattern window-splitting false negatives, since the window doesn't slide. Your pattern might get cut and split between two chunks, then not found even if it should match)

duplicates = chunks.dupecheck(
              min=5,
              max=10, 
              text=my_gen_text, 
              dataset=my_dataset, 
              verbose=False
            )

Sliding window find, try 1

• find word series at least 5 words long of your text string in dataset string

duplicates = sliding_window.dupecheck(
              min=5, 
              max=10, 
              text=my_gen_text, 
              dataset=my_dataset,
            )

Sliding window find try 2

• find word series at least 5 words long of your text string in dataset string.
• cleans text and dataset for you if you don't provide cleaned and specify cleaned=True.
• Cleaning is currently VERY slow.

duplicates = sliding_window2.dupecheck(
              min=5, 
              max=10, 
              text=my_gen_text, 
              dataset=my_dataset,
              cleaned=False,
              verbose=False
            )
