    Gender bias in Hindi word embedding
    (Indian Statistical Institute, Kolkata, 2021-07) Bharti, Barkha
    The purpose of this paper is to present a study on gender bias in word embeddings in the context of the Hindi Language. It has been shown that word embeddings capture human biases (such as gender bias) present in the corpus and how they relate words to each other. The Hindi-language word embeddings were chosen with the intent of giving insight into gender bias across a variety of domains, with the expectation that some would show significantly greater bias than others. We use WEAT’s hypothesis testing technique to confirm the presence of gender bias, and we find it useful for expanding the very narrow range of well-known gender bias word categories often used in the literature. We’ll test the presence of gender bias in four sets of word embeddings trained on corpora from different domains: Hindi CoNLL17, Hindi Wikipedia 2016 database dumps, and Bollywood lyrics dataset. We also mitigate the bias from the embedding by identifying the gender direction and quantifying the bias independent of its alignment with the crowd bias. Then, we’ll explore the efficacy of debiased embedding using Sentiment Analysis of Hindi Movie reviews and compare the results of sentiment analysis using original embedding and debiased embedding.
