Sentiment and structure in word co-occurrence networks on Twitter

no code implementations1 Oct 2021 Mikaela Irene Fudolig, Thayer Alshaabi, Michael V. Arnold, Christopher M. Danforth, Peter Sheridan Dodds

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.

1 code implementation15 Jun 2020 Thayer Alshaabi, David Rushing Dewhurst, James P. Bagrow, Peter Sheridan Dodds, Christopher M. Danforth

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.

Hahahahaha, Duuuuude, Yeeessss!: A two-parameter characterization of stretchable words and the dynamics of mistypings and misspellings

no code implementations9 Jul 2019 Tyler J. Gray, Christopher M. Danforth, Peter Sheridan Dodds

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

2 code implementations27 Jun 2019 David Rushing Dewhurst, Thayer Alshaabi, Dilan Kiley, Michael V. Arnold, Joshua R. Minot, Christopher M. Danforth, Peter Sheridan Dodds

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.

The emotional arcs of stories are dominated by six basic shapes

2 code implementations24 Jun 2016 Andrew J. Reagan, Lewis Mitchell, Dilan Kiley, Christopher M. Danforth, Peter Sheridan Dodds

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

no code implementations22 Jun 2016 Ryan J. Gallagher, Andrew J. Reagan, Christopher M. Danforth, Peter Sheridan Dodds

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.

Is language evolution grinding to a halt? The scaling of lexical turbulence in English fiction suggests it is not

no code implementations11 Mar 2015 Eitan Adam Pechenick, Christopher M. Danforth, Peter Sheridan Dodds

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

no code implementations7 Mar 2015 Jake Ryland Williams, Eric M. Clark, James P. Bagrow, Christopher M. Danforth, Peter Sheridan Dodds

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

no code implementations5 Jan 2015 Eitan Adam Pechenick, Christopher M. Danforth, Peter Sheridan Dodds

Zipf's law holds for phrases, not words

no code implementations19 Jun 2014 Jake Ryland Williams, Paul R. Lessard, Suma Desu, Eric Clark, James P. Bagrow, Christopher M. Danforth, Peter Sheridan Dodds

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

no code implementations15 Jun 2014 Peter Sheridan Dodds, Eric M. Clark, Suma Desu, Morgan R. Frank, Andrew J. Reagan, Jake Ryland Williams, Lewis Mitchell, Kameron Decker Harris, Isabel M. Kloumann, James P. Bagrow, Karine Megerdoomian, Matthew T. McMahon, Brian F. Tivnan, Christopher M. Danforth

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.
