Mitigating Gender Bias in Machine Learning Data Sets

Artificial Intelligence has the capacity to amplify and perpetuate societal biases and presents profound ethical implications for society. Gender bias has been identified in the context of employment advertising and recruitment tools, due to their reliance on underlying language processing and recommendation algorithms. Attempts to address such issues have involved testing learned associations, integrating concepts of fairness to machine learning and performing more rigorous analysis of training data. Mitigating bias when algorithms are trained on textual data is particularly challenging given the complex way gender ideology is embedded in language. This paper proposes a framework for the identification of gender bias in training data for machine learning.The work draws upon gender theory and sociolinguistics to systematically indicate levels of bias in textual training data and associated neural word embedding models, thus highlighting pathways for both removing bias from training data and critically assessing its impact.Comment: 10 pages, 5 figures, 5 Tables, Presented as Bias2020 workshop (as part of the ECIR Conference) - http://bias.disim.univaq.i

Language, Sexuality and Inclusive Pedagogy

This paper examines linguistic practices of inclusion and exclusion relating to sexual orientation and sexual identity as they surface in the context of language education and multilingual contexts. I argue that queer linguistics can provide a helpful theoretical framework for examining how normative and non‐normative constructions of sexual identity are enacted inscribed in language practices in classrooms, and how these language practices may effect particular discourses of sexuality. I examine extracts of interview data with young people analysed using APPRAISAL analysis. The analysis focuses on how language works as a form of social practice which can include and exclude sexual identities in classroom settings

Opposition as victimhood in newspaper debates about same-sex marriage

In this paper, we take a queer linguistics approach to the analysis of data from British newspaper articles which discuss the introduction of same-sex marriage. Drawing on methods from CDA and corpus linguistics, we focus on the construction of agency in relation to the government extending marriage to same-sex couples, and those resisting this. We show that opponents to same-sex marriage are represented and represent themselves as victims whose moral values, traditions, and civil liberties are being threatened by the state. Specifically, we argue that victimhood is invoked in a way that both enables and permits discourses of implicit homophobia

Effect of clinical signs, endocrinopathies, timing of surgery, hyperlipidemia, and hyperbilirubinemia on outcome in dogs with gallbladder mucocele

Gallbladder mucocele (GBM) is a common extra-hepatic biliary syndrome in dogs with death rates ranging from 7 to 45%. Therefore, the aim of this study was to identify the association of survival with variables that could be utilized to improve clinical decisions. A total of 1194 dogs with a gross and histopathological diagnosis of GBM were included from 41 veterinary referral hospitals in this retrospective study. Dogs with GBM that demonstrated abnormal clinical signs had significantly greater odds of death than subclinical dogs in a univariable analysis (OR, 4.2; 95% CI, 2.14–8.23; P < 0.001). The multivariable model indicated that categorical variables including owner recognition of jaundice (OR, 2.12; 95% CI, 1.19–3.77; P = 0.011), concurrent hyperadrenocorticism (OR 1.94; 95% CI, 1.08–3.47; P = 0.026), and Pomeranian breed (OR, 2.46; 95% CI 1.10–5.50; P = 0.029) were associated with increased odds of death, and vomiting was associated with decreased odds of death (OR, 0.48; 95% CI, 0.30–0.72; P=0.001). Continuous variables in the multivariable model, total serum/plasma bilirubin concentration (OR, 1.03; 95% CI, 1.01– 1.04; P < 0.001) and age (OR, 1.17; 95% CI, 1.08–1.26; P < 0.001), were associated with increased odds of death. The clinical utility of total serum/plasma bilirubin concentration as a biomarker to predict death was poor with a sensitivity of 0.61 (95% CI, 0.54–0.69) and a specificity of 0.63 (95% CI, 0.59–0.66). This study identified several prognostic variables in dogs with GBM including total serum/plasma bilirubin concentration, age, clinical signs, concurrent hyperadrenocorticism, and the Pomeranian breed. The presence of hypothyroidism or diabetes mellitus did not impact outcome in this study

Language use before and after Stonewall: a corpus-based study of gay men’s pre-Stonewall narratives

This study presents a contrastive corpus linguistic analysis of language use before and after Stonewall. It uses theoretical insights on normativity from the field of language and sexuality to investigate how the shifting normativities associated with the Stonewall Riots (1969) – widely considered the central event of gay liberation in the Western world – have shaped our conceptualization of sexuality as it surfaces in language use. Drawing on two corpora of gay men’s pre-Stonewall narratives dating from two time periods (before and after Stonewall, called PRE and POST), the analysis combines quantitative (keyword analysis, collocation analysis) and qualitative (concordance analysis) corpus linguistic methods to examine discursive shifts as evident from narrators’ language use. The study identifies the terms homosexual and normal as central contrastive labels in PRE, and gay and straight as corresponding terms in POST. Other discursive shifts detected are from sexual desire/practices to identity (and vice versa), from an individualistic to a community-based conceptualization of sexuality, and from unquestioned heteronormativity and gender binarism to a weakening of such dominant discourses. The findings are discussed in relation to the desire-identity shift, which is traditionally assumed to have taken place at the end of the 19th century, and shed new light on Stonewall as a central event for the development of an identity-based conceptualization of sexuality as we know it today
