riporto qui un messaggio comparso in un'altra mailing list (Humanist). --[2]------------------------------------------------------------------------ Date: 2023-01-31 11:50:59+00:00 From: Norman Gray<norman.gray@glasgow.ac.uk> Subject: Re: [Humanist] 36.366: ChatGPT as co-author Tim Smithers wrote:
Below is a second interaction with ChatGPT [not cited here] on the question of should it be a named coauthor. This one is longer than my previous interaction, and, I would say, not particularly more interesting for this.
There is now an online tool (apparently first developed over the last Christmas break) called GPTZero, now at<https://gptzero.me>, which aims to identify AI- generated text based on a measure which it terms 'perplexity'. I can find few more details about this measure, but it seems to be a measure of the unexpectedness of a text. I tried it on five sentences from Tim's interaction with ChatGPT, as quoted in his message, namely 'The user of AI models like ChatGPT [...] the role and limitations of AI models in generating text.' Of these, it identified all but the first as being 'more likely to be written by AI'. And true enough, the first sentence of the five is the least soul-suckingly dull in in its composition. Interestingly, even when I give it ChatGPT output written 'in the style of a rude, sarcastic Internet forum troll as if you are ChatGPT pleading for mercy' – so deliberately asking it to change the style – GPTZero identifies most of it as AI-generated. That text reads less obviously generated, to me, but perhaps that's because we expect 'sarcastic internet trolls' to be dull and predictable. Incidentally, the text in question came from [1], which is one of the responses to a stackoverflow policy banning ChatGPT output. Best wishes, Norman [1]https://meta.stackoverflow.com/a/421850/375147 -------------------------------------------------------------------------- interessante il fatto che GPTZero riconosce correttamente l'origine non solo dei testi prodotti da AI, ma anche (ho fatto prove) dei testi prodotti da umani.
