Addressing Age-Related Bias in Sentiment Analysis

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173986

論文アブストラクト: Computational approaches to text analysis are useful in understanding aspects of online interaction, such as opinions and subjectivity in text. Yet, recent studies have identified various forms of bias in language-based models, raising concerns about the risk of propagating social biases against certain groups based on sociodemographic factors (e.g., gender, race, geography). In this study, we contribute a systematic examination of the application of language models to study discourse on aging. We analyze the treatment of age-related terms across 15 sentiment analysis models and 10 widely-used GloVe word embeddings and attempt to alleviate bias through a method of processing model training data. Our results demonstrate that significant age bias is encoded in the outputs of many sentiment analysis algorithms and word embeddings. We discuss the models' characteristics in relation to output bias and how these models might be best incorporated into research.

A Large Inclusive Study of Human Listening Rates

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174018

論文アブストラクト: As conversational agents and digital assistants become increasingly pervasive, understanding their synthetic speech becomes increasingly important. Simultaneously, speech synthesis is becoming more sophisticated and manipulable, providing the opportunity to optimize speech rate to save users time. However, little is known about people's abilities to understand fast speech. In this work, we provide the first large-scale study on human listening rates. Run on LabintheWild, it used volunteer participants, was screen reader accessible, and measured listening rate by accuracy at answering questions spoken by a screen reader at various rates. Our results show that blind and low-vision people, who often rely on audio cues and access text aurally, generally have higher listening rates than sighted people. The findings also suggest a need to expand the range of rates available on personal devices. These results demonstrate the potential for users to learn to listen to faster rates, expanding the possibilities for human-conversational agent interaction.

Intellingo: An Intelligible Translation Environment

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174098

論文アブストラクト: Translation environments offer various translation aids to support professional translators. However, translation aids typically provide only limited justification for the translation suggestions they propose. In this paper we present Intellingo, a translation environment that explores intelligibility for translation aids, to enable more sensible usage of translation suggestions. We performed a comparative study between an intelligible version and a non-intelligible version of Intellingo. The results show that although adding intelligibility does not necessarily result in significant changes to the user experience, translators can better assess translation suggestions without a negative impact on their performance. Intelligibility is preferred by translators when the additional information it conveys benefits the translation process and when this information is not part of the translator's readily available knowledge.

"Only if you use English you will get to more things": Using Smartphones to Navigate Multilingualism

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174147

論文アブストラクト: We contribute to the intersection of multilingualism and human-computer interaction (HCI) with our investigation of language preferences in the context of the interface design of interactive systems. Through interview data collected from avid smartphone users located across distinct user groups in India, none of whom were native English speakers, we examine the factors that shape language choice and use on their mobile devices. Our findings indicate that these users frequently engage in English communication proactively and enthusiastically, despite their lack of English fluency, and we detail their motivations for doing so. We then discuss how language in technology use can be a way of putting forth mobility as an aspect of one's identity, making the case for an intersectional approach to studying language in HCI.
