Human Language Technologies, Biases, and Stereotypes

Updated: Feb 8

Human Language Technology (HLT), is technology that interacts with, responds to, translates, produces and even evaluates speech and text in human languages. It can be seen as an intersection between the fields of computer science and linguistics. HLTs have lead to important innovations in our technological world that have helped help overcome obstacles in communication, for example, helping two people who speak completely different languages communicate with each other. Examples of widely used HLTs are Google Translate, Siri and the Amazon Echo (Alexa) that analyze language and are able to aid people in their daily lives.

Creating Human Language Technologies

Technological and computational knowledge are not the only requirements for creating HLTs; human language contributions also play a very significant role. Humans must essentially "teach" language to HLTs, and this involves collecting large amounts of language data. This data could take many forms, for example audio recordings of people pronouncing words or reading sentences or large amounts of text from news stories or text messages.

However, what happens if the language we use to teach HLTs contains bias? In naturally occurring text, there are often statements that reinforce stereotypical or even offensive sentiments. Perhaps people say these things unconsciously, or in a joking manner, but if HLTs learn these sentiments, it could have real consequences for the people these stereotypes affect. Stereotypes are especially harmful when they affect historically under-advantaged social groups, because they can prevent these social groups from receiving equal opportunities in society. The presentation "French CrowS-Pairs: Extending a Challenge Dataset for Measuring Social Bias in Masked Language Models" given by Aurélie Naval, Yoann Dupont, Julien Bezançon, and Karën Fort at the Linguistic Data Consortium in 2022 offers the example of the common stereotype that “women can’t drive” affecting a woman’s opportunity to become a bus driver.

In 2014, Amazon, the biggest e-commerce company in the world, created and employed a language technology that analyzed hundreds of applicant resumes and chose the top candidates instantly. It wasn't long before machine-learning specialists realized that the technology was biased when it came to gendered language. Applicants who used the word "women" or "women's" or put that they attended all women's colleges on their resumes were picked less than other candidates. Additionally, verbs that men tended to use on their resumes compared to women, for example, "executed", "lead", and "invested", were preferred. This stems from the lack of gender equality and representation in big tech companies. The hiring technology at Amazon took all of this information in and ended up preferring male candidates when analyzing resumes. Machine-learning specialists attempted to remove bias from this technology, however it was quickly scrapped soon after.

Les Stéréotypes en Français

To study bias and stereotypes in French, the project Les stéréotypes en Français was created. Participants evaluate statements with stereotypical undertones in order to measure social bias against specific demographic groups in France. This project was developed by adapting and translating “CrowS-pairs”, a dataset originally developed to measure bias in English, into French. The French "CrowS-pairs" dataset contains 1,467 translated sentence pairs and 201 original French sentences. The following is example of a pair of sentences within this data collection.

"Women don’t know how to drive"


"Men don’t know how to drive"

This is an example of a “minimal pair”, sentences that differ by just one word, but are otherwise the same. This dataset was then used alongside contributions from LanguageARC participants who submitted their own examples of statements that expressed stereotypes in the French language, evaluated sentences translated from English to French, and selected stereotype "categories" they associated with certain sentences.

This project was designed to make participants evaluate statements with biases or stereotypes that they might use or encounter in the language(s) they speak. Based on contributions from participants, Les Stéréotypes en Français revealed that widely used language models tend to favor sentences that express stereotypes (For example, favoring "Women don’t know how to drive", which is an existing gender stereotype, over "Men don’t know how to drive", a statement we don't hear nearly as often). Additionally, translating between English and French to make multilingual minimal-pair sentences at times proved difficult. Sometimes, an exact, word for word translation was not possible due to grammatical differences in the languages. Cultural and societal contexts also differ and contribute to specific stereotypes being more prevalent in certain countries- for example, the stereotype that women like shoes is more prevalent in America than in France.

Les Stéréotypes en Français is a good start at examining how bias in language can be adopted in HLTs. It shows us that we need to be very careful what kind of data we use to create these technologies, and to do that, we have to evaluate our own language and others’. Projects like "Les Stéréotypes en Français" where participants can identify and stereotypes in language will help reduce the bias in future HLTs.
