    This thesis proposes a recalibration of Machine Learning for social biases to minimize harms from existing approaches and practices in the field. Prioritizing quality over quantity, accuracy over efficiency, representativeness over convenience, and situated thinking over universal thinking, the thesis demonstrates an alternative approach to creating Machine Learning models. Drawing on GLAM, the Humanities, the Social Sciences, and Design, the thesis focuses on understanding and communicating biases in a specific use case. 11,888 metadata descriptions from the University of Edinburgh Heritage Collections' Archives catalog were manually annotated for gender biases and text classification models were then trained on the resulting dataset of 55,260 annotations. Evaluations of the models' performance demonstrates that annotating gender biases can be automated; however, the subjectivity of bias as a concept complicates the generalizability of any one approach. The contributions are: (1) an interdisciplinary and participatory Bias-Aware Methodology, (2) a Taxonomy of Gendered and Gender Biased Language, (3) data annotated for gender biased language, (4) gender biased text classification models, and (5) a human-centered approach to model evaluation. The contributions have implications for Machine Learning, demonstrating how bias is inherent to all data and models; more specifically for Natural Language Processing, providing an annotation taxonomy, annotated datasets and classification models for analyzing gender biased language at scale; for the Gallery, Library, Archives, and Museum sector, offering guidance to institutions seeking to reconcile with histories of marginalizing communities through their documentation practices; and for historians, who utilize cultural heritage documentation to study and interpret the past. Through a real-world application of the Bias-Aware Methodology in a case study, the thesis illustrates the need to shift away from removing social biases and towards acknowledging them, creating data and models that surface the uncertainty and multiplicity characteristic of human societies

    Talking about personal recovery in bipolar disorder: Integrating health research, natural language processing, and corpus linguistics to analyse peer online support forum posts

    Background: Personal recovery, ‘living a satisfying, hopeful and contributing lifeeven with the limitations caused by the illness’ (Anthony, 1993) is of particular value in bipolar disorder where symptoms often persist despite treatment. So far, personal recovery has only been studied in researcher-constructed environments (interviews, focus groups). Support forum posts can serve as a complementary naturalistic data source. Objective: The overarching aim of this thesis was to study personal recovery experiences that people living with bipolar disorder have shared in online support forums through integrating health research, NLP, and corpus linguistics in a mixed methods approach within a pragmatic research paradigm, while considering ethical issues and involving people with lived experience. Methods: This mixed-methods study analysed: 1) previous qualitative evidence on personal recovery in bipolar disorder from interviews and focus groups 2) who self-reports a bipolar disorder diagnosis on the online discussion platform Reddit 3) the relationship of mood and posting in mental health-specific Reddit forums (subreddits) 4) discussions of personal recovery in bipolar disorder subreddits. Results: A systematic review of qualitative evidence resulted in the first framework for personal recovery in bipolar disorder, POETIC (Purpose & meaning, Optimism & hope, Empowerment, Tensions, Identity, Connectedness). Mainly young or middle-aged US-based adults self-report a bipolar disorder diagnosis on Reddit. Of these, those experiencing more intense emotions appear to be more likely to post in mental health support subreddits. Their personal recovery-related discussions in bipolar disorder subreddits primarily focussed on three domains: Purpose & meaning (particularly reproductive decisions, work), Connectedness (romantic relationships, social support), Empowerment (self-management, personal responsibility). Support forum data highlighted personal recovery issues that exclusively or more frequently came up online compared to previous evidence from interviews and focus groups. Conclusion: This project is the first to analyse non-reactive data on personal recovery in bipolar disorder. Indicating the key areas that people focus on in personal recovery when posting freely and the language they use provides a helpful starting point for formal and informal carers to understand the concerns of people diagnosed with bipolar disorder and to consider how best to offer support

    Referring to discourse participants in Ibero-Romance languages

    Get PDF
    Synopsis: This volume brings together contributions by researchers focusing on personal pronouns in Ibero-Romance languages, going beyond the well-established variable of expressed vs. non-expressed subjects. While factors such as agreement morphology, topic shift and contrast or emphasis have been argued to account for variable subject expression, several corpus studies on Ibero-Romance languages have shown that the expression of subject pronouns goes beyond these traditionally established factors and is also subject to considerable dialectal variation. One of the factors affecting choice and expression of personal pronouns or other referential devices is whether the construction is used personally or impersonally. The use and emergence of new impersonal constructions, eventually also new (im)personal pronouns, as well as the variation found in the expression of human impersonality in different Ibero-Romance language varieties is another interesting research area that has gained ground in the recent years. In addition to variable subject expression, similar methods and theoretical approaches have been applied to study the expression of objects. Finally, the reference to the addressee(s) using different address pronouns and other address forms is an important field of study that is closely connected to the variable expression of pronouns. The present book sheds light on all these aspects of reference to discourse participants. The volume contains contributions with a strong empirical background and various methods and both written and spoken corpus data from Ibero-Romance languages. The focus on discourse participants highlights the special properties of first and second person referents and the factors affecting them that are often different from the anaphoric third person. The chapters are organized into three thematic sections: (i) Variable expression of subjects and objects, (ii) Between personal and impersonal, and (iii) Reference to the addressee

    Comparing the production of a formula with the development of L2 competence

    Get PDF
    This pilot study investigates the production of a formula with the development of L2 competence over proficiency levels of a spoken learner corpus. The results show that the formula in beginner production data is likely being recalled holistically from learners’ phonological memory rather than generated online, identifiable by virtue of its fluent production in absence of any other surface structure evidence of the formula’s syntactic properties. As learners’ L2 competence increases, the formula becomes sensitive to modifications which show structural conformity at each proficiency level. The transparency between the formula’s modification and learners’ corresponding L2 surface structure realisations suggest that it is the independent development of L2 competence which integrates the formula into compositional language, and ultimately drives the SLA process forward

    The Witcraft of Seeing Things Differently : Hyperdetermined Humor, Unusual Viewpoints, and Narrative Rhetoric in Terry Pratchett's Discworld Novels

    Sir Terry Pratchettin maineikasta ja menestynyttĂ€ Discworld-romaanisarjaa luonnehditaan yleensĂ€ koomiseksi fantasiaksi, ja vaikka sitĂ€ on aiemmin tutkittu etupÀÀssĂ€ fantasiakirjallisuutena, niin fantasiamiljöön lisĂ€ksi toinen nĂ€iden kirjojen silmiinpistĂ€vĂ€ piirre on huumorin ylenpalttinen runsaus. TĂ€ssĂ€ vĂ€itöskirjassa olen valinnut harvinaisemman lĂ€hestymistavan tutkiessani Discworld-romaaneja ensisijaisesti humoristisena kirjallisuutena, ja sen mukaisesti vĂ€itöskirjani keskeisimpĂ€nĂ€ tavoitteena on tutkia Terry Pratchettin huumorin poetiikkaa. Tarkemmin sanottuna olen asettanut tĂ€ssĂ€ vĂ€itöskirjassa tehtĂ€vĂ€kseni kartoittaa Terry Pratchettin huumorille ominaisimmat komiikan keinot ja tutkia, mikĂ€ tekee Discworld-romaaneista hauskoja. Discworld-romaaneille ominainen huumorin runsaus koostuu humorististen kuvausten ja koomisten kohtausten tiheĂ€n esiintymisen lisĂ€ksi komiikan keinojen laajasta valikoimasta. TĂ€ssĂ€ vĂ€itöskirjassa vĂ€itĂ€n, ettĂ€ Terry Pratchettin huumori on hyperdeterminoitua, mikĂ€ tarkoittaa, ettĂ€ hĂ€n yhdistelee erilaisia komiikan keinoja samassa kuvauksessa tai kohtauksessa. Siksi Pratchettin huumorin poetiikkaa kĂ€sittelevĂ€ vĂ€itöskirjani on samalla myös tutkimus hyperdeterminoidun huumorin rakentumisesta. SelkeyttÀÀkseni huumorin hyperdeterminaation rakentumista jaottelen komiikan keinot neljÀÀn kategoriaan: tilanteellisiin, kontekstuaalisiin, rakenteellisiin ja tyylillisiin. Sovellan tĂ€tĂ€ jaottelua vĂ€ittĂ€mĂ€llĂ€, ettĂ€ humoristista kuvausta tai koomista kohtausta voidaan perustellusti sanoa hyperdeterminoiduksi silloin, kun siinĂ€ yhdistellÀÀn komiikan keinoja useammasta kuin yhdestĂ€ kategoriasta. PidĂ€n Pratchettin huumorille ominaisten komiikan keinojen kartoittamista yhtenĂ€ tĂ€mĂ€n vĂ€itöskirjan keskeisimmistĂ€ kontribuutioista kirjallisen huumorin tutkimukselle. Tilanteellisista komiikan keinoista tarkastelen Discworld-romaaneista löytĂ€miĂ€ni esimerkkejĂ€ draamallisesta ironiasta ja absurdista logiikasta. Kontekstuaalisista komiikan keinoista kĂ€sittelen Pratchettin parodiaa ja satiiria, kun taas rakenteellisista komiikan keinoista tutkin, kuinka Pratchett kĂ€yttÀÀ paraprosdokiania, bathosta, toistuvia piloja (”figgin”) ja koomisia alaviitteitĂ€. TyylillisistĂ€ komiikan keinoista tutkailen Pratchettin koomisia kielikuvia (hyperbolia, metaforia, vertauksia ja personifikaatioita), hĂ€nen sanaleikkejÀÀn (paronomasia, antanaklasis, sanataskut ja kaksikieliset sanaleikit) sekĂ€ Pratchettin koomisia eufemismeja. LisĂ€ksi osoitan vĂ€itöskirjassani, ettĂ€ Terry Pratchettin huumorille on ominaista kulttuuristen kliseiden (eli tuttujen kulttuuri-ilmiöiden, totunnaisten ajattelutapojen ja vakiintuneiden esittĂ€misen konventioiden) esittĂ€minen humoristisen epĂ€tavallisista nĂ€kökulmista kĂ€sin. Discworld-romaaneissa Pratchett siirtÀÀ erilaisia oman maailmamme kulttuuri-ilmiöitĂ€ Discworld-nimiseen (suom. Kiekkomaailma) fantasiamaailmaansa, ja tĂ€mĂ€n maailmojen törmĂ€yttĂ€misen seurauksena kulttuuriset kliseet nĂ€yttĂ€ytyvĂ€t lukijalle samanaikaisesti tuttuina ja koomisen outoina. TĂ€llaiset humoristiset nĂ€kökulmat vahvistavat osaltaan huumorin hyperdeterminaatiota. Samalla kun fantasiamiljöö mahdollistaa kahden maailman koomisen törmĂ€yttĂ€misen ja oman maailmamme kulttuuristen kliseiden peilaamisen toisen maailman avulla, huumori toisaalta mahdollistaa Kiekkomaailmassa normaalia fantasiaa vapaamman mielikuvituksen lennon, eikĂ€ monia Discworld-romaaneissa kuvattuja asioita, tapahtumia ja ilmiöitĂ€ voisi esiintyĂ€ maailmoissa, jotka eivĂ€t rakennu absurdin logiikan, kulttuurisilla kliseillĂ€ leikittelyn ja koomisen liioittelun kaltaisten todellisuuta vÀÀristĂ€vien periaatteiden luoman ”taikuuden” varaan. Komiikan keinojen moninaisuuden, hyperdeterminoidun huumorin ja epĂ€tavallisten nĂ€kökulmien lisĂ€ksi tutkin vĂ€itöskirjassani sitĂ€, millaisia arvottavia asenteita kertojan humoristiset nĂ€kökulmat ja humoristisiin kuvauksiin sisĂ€ltyvĂ€t henkilöhahmojen tunnereaktiot paljastavat. Tulkitsen tĂ€llaisen arvottavan huumorin kirjalliseksi retorisen vaikuttamisen keinoksi, jonka avulla kirjailija pyrkii ohjailemaan lukijansa hyvĂ€ksyviĂ€ ja paheksuvia asenteita. Useimmiten Pratchettin huumori on kulttuurikriittistĂ€, eli parodista ja satiirista, mutta toisinaan humoristiset nĂ€kökulmat esittĂ€vĂ€t todellisen maailman kulttuuri-ilmiöitĂ€ myönteisinĂ€ ja ihailtavina. VĂ€itĂ€n tutkimuksessani, ettĂ€ kirjallisuuden retoriikka perustuu tĂ€llaisten kielteisten ja myönteisten asenteiden esittĂ€miselle ja ettĂ€ huumori on yksi kertomuksen retoriikan vaikutuskeinoista.Sir Terry Pratchett’s bestselling Discworld series of novels has been commonly described as comic fantasy, and although it has been previously studied mainly as fantasy literature, another conspicuous feature in these novels, in addition to the fantasy milieu, is their rich and abundant humor. In this study, I have chosen the road less travelled by approaching the Discworld novels as humorous literature, and, consequently, my main goal here is to study the poetics of Terry Pratchett’s humor— his “witcraft”. To be more precise, in this dissertation I have set myself the task of mapping out the comic devices that are most characteristic for Terry Pratchett’s witcraft and investigating what makes the Discworld novels funny. The richness of humor that is characteristic for the Discworld novels consists partly of the frequent occurrences of humorous descriptions and comic scenes, but also of the numerous comic devices that Pratchett deploys. In this dissertation, I argue that Terry Pratchett’s humor is hyperdetermined, which means that he tends to combine numerous comic devices in the same description or scene. Consequently, this study on the poetics of Terry Pratchett’s humor is at the same time a study on the construction of hyperdetermined humor. To better understand how hyperdetermined humor is constructed, I have devised a taxonomy that divides comic devices into four categories: situational, contextual, structural, and stylistic. Based on this taxonomy, I argue that the humor of a humorous description or a comic scene can be said to be truly hyperdetermined whenever it combines comic devices from more than one of these categories. I consider mapping out the comic devices that are most characteristic for Terry Pratchett’s witcraft to be one of the major contributions of this dissertation to the academic study of humor in literature. Of situational comic devices, I discuss and analyze examples of dramatic irony and absurd logic that I have detected in the Discworld novels. Of contextual comic devices, I discuss Pratchett’s parody and satire; of structural comic devices, I study Pratchett’s use of paraprosdokian, bathos, figgins (or running gags), and comic footnotes. Of stylistic comic devices, I investigate Pratchett’s comic imagery (hyperboles, metaphors, similes, and personifications), his puns (paronomasia, antanaclasis, portmanteaux, and bilingual puns), as well as Pratchett’s comic euphemisms. In this dissertation, I also demonstrate that representing cultural clichĂ©s (i.e., familiar cultural phenomena, customary ways of thinking, and conventional ways of representing) from humorously unusual viewpoints is characteristic for Terry Pratchett’s witcraft. In the Discworld novels, Pratchett transfers various cultural phenomena from the real world, our “Roundworld”, to a fantasy world called the Discworld, and as a result of this interworldly resonance, the cultural clichĂ©s of our Roundworld appear to the reader simultaneously as familiar and comically strange. These humorous viewpoints can be viewed as an additional constituent of hyperdetermined humor. While the fantasy setting of the Discworld novels allows Pratchett to set up comic resonance between the worlds, Pratchett’s humor also makes the Discworld a more imaginative and fantastic place than typical fantasy worlds. Many events and phenomena that are represented in the Discworld novels can only exist in a world where reality is distorted and enhanced by the special “magic” of comically absurd logic, playing with cultural clichĂ©s, and humorous exaggerations. In addition to the abundance of comic devices, hyperdetermined humor, and humorously unusual viewpoints, I also study in this dissertation what kinds of evaluative attitudes the narrator’s humorous viewpoints and the characters’ emotional reactions reveal. According to my interpretation, such evaluative attitudes are means of narrative rhetoric, where the author attempts to guide the reader’s attitudes of approval or disapproval. Pratchett’s humor is often critical—parodical or satirical—although occasionally the narrator’s humorous viewpoints represent the cultural phenomena of our Roundworld in a positive light, as something admirable. In this dissertation, I argue that narrative rhetoric is based on representing negative and positive attitudes, and that humor is one possible means of narrative rhetoric

    Causal inference: relating language to event representations and events in the world

    Get PDF
    Events are not isolated but rather linked to one another in various dimensions. In language processing, various sources of information—including real-world knowledge, (representations of) current linguistic input and non-linguistic visual context—help establish causal connections between events. In this review, we discuss causal inference in relation to events and event knowledge as one aspect of world knowledge, and their representations in language comprehension. To evaluate the mechanism and time course of causal inference, we gather insights from studies on (1) implicit causality/consequentiality as a specific form of causal inference regarding the protagonists of cause/consequence events, and (2) the processing of causal relations. We highlight the importance of methodology in measuring causal inference, compare the results from different research methods, and emphasize the contribution of the visual-world paradigm to achieve a better understanding of causal inference. We recommend that further investigations of causal inference consider temporally sensitive measures and more detailed contexts

    Ditransitives in germanic languages. Synchronic and diachronic aspects

    Full text link
    This volume brings together twelve empirical studies on ditransitive constructions in Germanic languages and their varieties, past and present. Specifically, the volume includes contributions on a wide variety of Germanic languages, including English, Dutch, and German, but also Danish, Swedish, and Norwegian, as well as lesser-studied ones such as Faroese. While the first part of the volume focuses on diachronic aspects, the second part showcases a variety of synchronic aspects relating to ditransitive patterns. Methodologically, the volume covers both experimental and corpus-based studies. Questions addressed by the papers in the volume are, among others, issues like the cross-linguistic pervasiveness and cognitive reality of factors involved in the choice between different ditransitive constructions, or differences and similarities in the diachronic development of ditransitives. The volume’s broad scope and comparative perspective offers comprehensive insights into well-known phenomena and furthers our understanding of variation across languages of the same family
