20.500.12556/RUL-135582 Hate speech paraphraser Parafraziranje sovražnega govora There is plenty of hate speech on the web, which is additionally enabled by the possibility to remain anonymous, and many forums as well as news websites are trying to fight against it with a large number of moderators that remove hateful comments. Due to large numbers of daily comments they use automated hate speech detection software. We propose a DPhate system, which outputs an unhateful alternative to the posted hateful comment. The system uses a series of pre-trained paraphrasing models, that generate nonhateful sentences. The automatic evaluation has shown that in 84.37% of cases at least one acceptable sentence is generated, whereas only 67.90% of rephrasals were deemed acceptable by human evaluators. Splet je poln sovražnega govora, ki ga dodatno spodbuja možnost anonimnosti. Mnogi forumi in novičarske spletne strani se branijo z moderatorji, ki odstranijo škodljive komentarje. Ker je po navadi komentarjev veliko (več deset tisoč na dan), si moderatorji pomagajo s programi za avtomatsko zaznavanje sovražnega govora. V svoji diplomski nalogi predlagamo nov sistem DPhate, ki uporabniku ob objavi sovražnega komentarja predlaga nesovražno alternativo z ohranjenim pomenom. V sistemu uporabimo več prednaučenih modelov, ki s parafraziranjem generirajo nesovražne povedi. Avtomatska evalvacija je pokazala, da se v 84.37% generira vsaj en primeren stavek, medtem ko so generirane parafraze človeški evalvatorji ocenili za primerne v 67.90%. hate speech natural language processing transformers BERT models machine learning paraphrasing sovražni govor obdelava naravnega jezika transformerji modeli BERT strojno učenje parafraziranje true false false Angleški jezik Slovenski jezik Diplomsko delo/naloga 2022-03-21 11:25:00 2022-03-21 11:25:03 2022-09-14 04:14:05 0000-00-00 00:00:00 2022 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 30961 102617091 Pesjak_Drejc_-_Parafraziranje_sovraznega_govora.pdf Pesjak_Drejc_-_Parafraziranje_sovraznega_govora.pdf 1 56A15C3E11790DFA42A53DD8ADE72F14 438869b6b51c7d3b8a2b356657ac2f2972d926f4d87aa0ef449492e35f563778 2b8cacda-a901-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154738 Fakulteta za računalništvo in informatiko 0 0 0
