The Resume Paradox: Greater Language Differences, Smaller Pay Gaps
This suggests that females' resumes that are semantically similar to males' resumes may have greater wage parity.
A blind spot for large language models: Supradiegetic linguistic information
We propose that considering what it is like to be an LLM like ChatGPT, as Nagel might have put it, can help us gain insight into its capabilities in general, and in particular, that its exposure to linguistic training data can be productively reframed as exposure to the diegetic information encoded in language, and its deficits can be reframed as ignorance of extradiegetic information, including supradiegetic linguistic information.
An assessment of measuring local levels of homelessness through proxy social media signals
An increase to the log-odds of ``homeless'' appearing in an English-language tweet, as well as an acceleration in the increase in average tweet sentiment, suggest that tweets about homelessness are also affected by trends at the nation-scale.
Curating corpora with classifiers: A case study of clean energy sentiment online
Both of these drawbacks could be overcome with a real-time, high volume data stream and fast analysis pipeline.
A decomposition of book structure through ousiometric fluctuations in cumulative word-time
Our findings suggest that, in the ousiometric sense, longer books are not expanded versions of shorter books, but are more similar in structure to a concatenation of shorter texts.
Sentiment and structure in word co-occurrence networks on Twitter
We explore the relationship between context and happiness scores in political tweets using word co-occurrence networks, where nodes in the network are the words, and the weight of an edge is the number of tweets in the corpus for which the two connected words co-occur.

Sirius: Visualization of Mixed Features as a Mutual Information Network Graph
Data scientists across disciplines are increasingly in need of exploratory analysis tools for data sets with a high volume of features of mixed data type (quantitative continuous and discrete categorical).
Quantifying language changes surrounding mental health on Twitter
Mental health challenges are thought to afflict around 10% of the global population each year, with many going untreated due to stigma and limited access to services.
The incel lexicon: Deciphering the emergent cryptolect of a global misogynistic community
Evolving out of a gender-neutral framing of an involuntary celibate identity, the concept of `incels' has come to refer to an online community of men who bear antipathy towards themselves, women, and society-at-large for their perceived inability to find and maintain sexual relationships.
Interpretable bias mitigation for textual data: Reducing gender bias in patient notes while maintaining classification performance
Medical systems in general, and patient treatment decisions and outcomes in particular, are affected by bias based on gender and other demographic elements.
Generalized Word Shift Graphs: A Method for Visualizing and Explaining Pairwise Comparisons Between Texts
A common task in computational text analyses is to quantify how two corpora differ according to a measurement like word frequency, sentiment, or information content.
Storywrangler: A massive exploratorium for sociolinguistic, cultural, socioeconomic, and political timelines using Twitter
In real-time, social media data strongly imprints world events, popular culture, and day-to-day conversations by millions of ordinary people at a scale that is scarcely conventionalized and recorded.
The sociospatial factors of death: Analyzing effects of geospatially-distributed variables in a Bayesian mortality model for Hong Kong
However, the extent to which mortality in a geographical region is a function of socioeconomic factors in both that region and its neighbors is unclear.

The growing amplification of social media: Measuring temporal and social contagion dynamics for over 150 languages on Twitter for 2009-2020
We find that for the most common languages on Twitter there is a growing tendency, though not universal, to retweet rather than share new content.
Hahahahaha, Duuuuude, Yeeessss!: A two-parameter characterization of stretchable words and the dynamics of mistypings and misspellings
Stretched words like `heellllp' or `heyyyyy' are a regular feature of spoken language, often used to emphasize or exaggerate the underlying meaning of the root word.
The shocklet transform: A decomposition method for the identification of local, mechanism-driven dynamics in sociotechnical time series
We introduce a qualitative, shape-based, timescale-independent time-domain transform used to extract local dynamics from sociotechnical time series---termed the Discrete Shocklet Transform (DST)---and an associated similarity search routine, the Shocklet Transform And Ranking (STAR) algorithm, that indicates time windows during which panels of time series display qualitatively-similar anomalous behavior.

Scaling of inefficiencies in the U.S. equity markets: Evidence from three market indices and more than 2900 securities
Using the most comprehensive, commercially-available dataset of trading activity in U. S. equity markets, we catalog and analyze quote dislocations between the SIP National Best Bid and Offer (NBBO) and a synthetic BBO constructed from direct feeds.
Fragmentation and inefficiencies in US equity markets: Evidence from the Dow 30
Using the most comprehensive source of commercially available data on the US National Market System, we analyze all quotes and trades associated with Dow 30 stocks in 2016 from the vantage point of a single and fixed frame of reference.
Visitors to urban greenspace have higher sentiment and lower negativity on Twitter
With more people living in cities, we are witnessing a decline in exposure to nature.
A Sentiment Analysis of Breast Cancer Treatment Experiences and Healthcare Perceptions Across Twitter
Conclusions: Social media can provide a positive outlet for patients to discuss their needs and concerns regarding their healthcare coverage and treatment needs.
English verb regularization in books and tweets
We find that the extent of verb regularization is greater on Twitter, taken as a whole, than in English Fiction books.
Forecasting the onset and course of mental illness with Twitter data
Twitter data and details of depression history were collected from 204 individuals (105 depressed, 99 healthy).

The emotional arcs of stories are dominated by six basic shapes
Advances in computing power, natural language processing, and digitization of text now make it possible to study a culture's evolution through its texts using a "big data" lens.
Divergent discourse between protests and counter-protests: #BlackLivesMatter and #AllLivesMatter
Since the shooting of Black teenager Michael Brown by White police officer Darren Wilson in Ferguson, Missouri, the protest hashtag #BlackLivesMatter has amplified critiques of extrajudicial killings of Black Americans.
What we write about when we write about causality: Features of causal statements across large-scale social discourse
Identifying and communicating relationships between causes and effects is important for understanding our world, but is affected by language structure, cognitive and emotional biases, and the properties of the communication medium.
Zipf's law is a consequence of coherent language production
The task of text segmentation may be undertaken at many levels in text analysis---paragraphs, sentences, words, or even letters.
Benchmarking sentiment analysis methods for large-scale texts: A case for using continuum-scored words and word shift graphs
The emergence and global adoption of social media has rendered possible the real-time estimation of population-scale sentiment, bearing profound implications for our understanding of human behavior.
Nonlinear functional mapping of the human brain
In the present study, we introduce just such a method, called nonlinear functional mapping (NFM), and demonstrate its application in the analysis of resting state fMRI from a 242-subject subset of the IMAGEN project, a European study of adolescents that includes longitudinal phenotypic, behavioral, genetic, and neuroimaging data.

Twitter, a popular social media outlet, has evolved into a vast source of linguistic data, rich with opinion, sentiment, and discussion.
Is language evolution grinding to a halt? The scaling of lexical turbulence in English fiction suggests it is not
Of basic interest is the quantification of the long term growth of a language's lexicon as it develops to more completely cover both a culture's communication requirements and knowledge space.
Identifying missing dictionary entries with frequency-conserving context models
With our predictions we then engage the editorial community of the Wiktionary and propose short lists of potential missing entries for definition, developing a breakthrough, lexical extraction technique, and expanding our knowledge of the defined English lexicon of phrases.
Characterizing the Google Books corpus: Strong limits to inferences of socio-cultural and linguistic evolution
However, the Google Books corpus suffers from a number of limitations which make it an obscure mask of cultural popularity.
Text mixing shapes the anatomy of rank-frequency distributions: A modern Zipfian mechanics for natural language
Natural languages are full of rules and exceptions.
Zipf's law holds for phrases, not words
With Zipf's law being originally and most famously observed for word frequency, it is surprisingly limited in its applicability to human language, holding over no more than three to four orders of magnitude before hitting a clear break in scaling.
Human language reveals a universal positivity bias
Using human evaluation of 100, 000 words spread across 24 corpora in 10 languages diverse in origin and culture, we present evidence of a deep imprint of human sociality in language, observing that (1) the words of natural human language possess a universal positivity bias; (2) the estimated emotional content of words is consistent between languages under translation; and (3) this positivity bias is strongly independent of frequency of word usage.
