BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:9975,
author = {Giuseppe Fenza and Vincenzo Loia and Paola Montserrat Mainardi and Claudio Stanzione},
title = {OSINT Knowledge Graph for Fact-Checking: Google Map Hacks Debunking},
howpublished = {EasyChair Preprint 9975},
year = {EasyChair, 2023}}
