Abstract

AbstractUnbiased and fair reporting is an integral part of ethical journalism. Yet, political propaganda and one-sided views can be found in the news and can cause distrust in media. Both accidental and deliberate political bias affect the readers and shape their views. We contribute to a trustworthy media ecosystem by automatically identifying politically biased news articles. We introduce novel corpora annotated by two communities, i.e., domain experts and crowd workers, and we also consider automatic article labels inferred by the newspapers’ ideologies. Our goal is to compare domain experts to crowd workers and also to prove that media bias can be detected automatically. We classify news articles with a neural network and we also improve our performance in a self-supervised manner.

Along with these neural signals and the text of the story, we also provide a variety of word-by-word predictors motivated by research in computational linguistics and cognitive science. These predictors range from prosody to morphology to syntax. These annotated, naturalistic datasets can be used to replicate prior work and test new hypotheses about natural language comprehension in the brain.

Introduction While there has been a tradition of using naturalistic lan- guage corpora in computational linguistics, this practice has only recently become popular within the cognitive neu- roscience of language. In this neighboring field “naturalis- tic” stimuli are now offering a new way to study language comprehension in the brain, in synergy with natural lan- guage processing (NLP) tools (Armeni et al., 2017; Bren- nan, 2016). From a neurolinguistic perspective, contextually-situated naturalistic stimuli present an opportunity to investigate multiple linguistic levels, including phonemes, syllables, words, phrases, sentences and discourse, all simultaneously within the same dataset. Such an opportunity creates new avenues for linking hypotheses between various linguis- tic representations and neurobiological architectures in the brain (Kandylaki and Bornkessel-Schlesewsky, 2019). This paper introduces a new language resource, the Al- ice Datasets, which is naturalistic in this sense (Maguire, 2012; Willems, 2015; Hamilton and Huth, 2018). It pack- ages together neuroimaging and electrophysiological mea- sures from many speakers listening to the same text – the first chapter of Lewis Carroll’s Alice’s Adventure in Won- derland (1865). It shares an underlying book with the cross-linguistic project, Alice in the Language Localizer Wonderland (Fedorenko, 2016) and an emphasis on nat- uralistic text with the Narrative Brain Dataset (Lopopolo et al., 2018) (hereafter NBD). However the current project is based on a longer continuous narrative than in either of these projects (12 mins 24 secs vs 6 mins 30 secs on an av- erage for NBD). This larger corpus facilitates the study of linguistic phenomena that may not be attested sufficiently often in smaller samples. The Alice Datasets include both high spatial resolution (fMRI) and high temporal resolution (EEG) neural signals. And since this resource is in English (rather than Dutch, the language of the NBD), it offers the chance to apply a very wide array of speech and natural language technologies. Together, these properties make the Alice Datasets a first-line choice for those seeking to com- pare AI …
