Large Language Models(LLMs)are increasingly demonstrating their ab.lity to understand natural language and solve complex tasks,especially through text *** of the relevant capab.lities is contextual learning,which involves the ab.lity to receive instructions in natural language or task demonstrations to generate expected outputs for test instances without the need for additional training or gradient *** recent years,the popularity of social networking has provided a medium through which some users can engage in offensive and harmful online *** this study,we investigate the ab.lity of different LLMs,ranging from zero-shot and few-shot learning to *** experiments show that LLMs can identify sexist and hateful online texts using zero-shot and few-shot approaches through information ***,it is found that the encoder-decoder model called Zephyr achieves the b.st results with the fine-tuning approach,scoring 86.811%on the Explainab.e Detection of Online Sexism(EDOS)test-set and 57.453%on the Multilingual Detection of Hate Speech Against Immigrants and Women in Twitter(HatEval)***,it is confirmed that the evaluated models perform well in hate text detection,as they b.at the b.st result in the HatEval task *** error analysis shows that contextual learning had difficulty distinguishing b.tween types of hate speech and figurative ***,the fine-tuned approach tends to produce many false positives.
