The applications of Computational Linguistics (CL) and Natural Language Processing (NLP) systems are seen everywhere in day-to-day life. Search engines, virtual assistants, translation apps, and email all use these systems. As CL and NLP systems advance and become more commonly used, it’s critical to recognize the pitfalls and ethical implications that may accompany them.
CL and NLP systems are greatly beneficial. They power customer service chatbots and can facilitate communication between people who speak different languages. However, as the field of NLP progresses, NLP models are getting better at generating realistic-sounding text, and it’s becoming increasingly easy to use these systems to generate articles or social media posts that contain misinformation under the guise of a human author, potentially leading to people making poor decisions based on this false information. Another potential repercussion is that people could be more likely to distrust legitimate sources of information if they are unable to distinguish between real and fake sources. In addition, CL and NLP systems make it easier for scammers to create convincing conversations with potential victims who don’t recognize that it’s not a human speaking to them. While these issues come from user applications of CL and NLP systems, ethical implications are also rooted in the creation of such systems.
A common issue in machine learning models is data bias. The idea is that the model will produce biased, or unfair outputs if the dataset it was trained on contains unequal amounts of data on different demographics, or data that is not diverse enough. Data bias is a significant issue in all fields that use machine learning, however, it is particularly important in NLP due to how heavily impacted by personal background language and communication is. A potential consequence of data bias in NLP models is perpetuating stereotypes and societal inequalities. Numerous real-world ramifications may be introduced because of data bias in NLP models.
For instance, if an NLP model that is designed to approve or deny loan applications is trained on a dataset that contains more applications from men than women, it is more likely to approve loan applications from men than women. Similarly, an NLP model designed to screen job applications is more likely to select applicants of a certain demographic over others if the data it was trained on contains mainly applications of people of that demographic.
It is critical for developers to recognize the ethical issues that can come with the NLP models they train and for organizations to consider the potential bias in the NLP systems they use before they apply them. I think that CL and NLP systems can prove to be incredibly powerful tools and that we can work around these issues, what do you think?
