Machine-assisted mixed methods: augmenting humanities and social sciences with artificial intelligence

1 code implementation24 Sep 2023 Andres Karjus

The increasing capacities of large language models (LLMs) present an unprecedented opportunity to scale up data analytics in the humanities and social sciences, augmenting and automating qualitative analytic tasks previously typically allocated to human labor.

Evolving linguistic divergence on polarizing social media

1 code implementation4 Sep 2023 Andres Karjus, Christine Cuskley

Here we map and quantify linguistic divergence across the partisan left-right divide in the United States, using social media data.

Reliable Detection and Quantification of Selective Forces in Language Change

no code implementations25 May 2023 Juan Guerrero Montero, Andres Karjus, Kenny Smith, Richard A. Blythe

Language change is a cultural evolutionary process in which variants of linguistic variables change in frequency through processes analogous to mutation, selection and genetic drift.

Collection Space Navigator: An Interactive Visualization Interface for Multidimensional Datasets

2 code implementations11 May 2023 Tillmann Ohm, Mar Canet Solà, Andres Karjus, Maximilian Schich

We introduce the Collection Space Navigator (CSN), a browser-based visualization tool to explore, research, and curate large collections of visual digital artifacts that are associated with multidimensional data, such as vector embeddings or tables of metadata.

Compression ensembles quantify aesthetic complexity and the evolution of visual art

no code implementations20 May 2022 Andres Karjus, Mar Canet Solà, Tillmann Ohm, Sebastian E. Ahnert, Maximilian Schich

The quantification of visual aesthetics and complexity have a long history, the latter previously operationalized via the application of compression algorithms.

Conceptual similarity and communicative need shape colexification: an experimental study

1 code implementation19 Mar 2021 Andres Karjus, Richard A. Blythe, Simon Kirby, Tianyu Wang, Kenny Smith

Colexification refers to the phenomenon of multiple meanings sharing one word in a language.

Communicative need modulates competition in language change

1 code implementation16 Jun 2020 Andres Karjus, Richard A. Blythe, Simon Kirby, Kenny Smith

By contrast, in topics which are increasing in importance for language users, near-synonymous words tend not to compete directly and can coexist.

Challenges in detecting evolutionary forces in language change using diachronic corpora

1 code implementation3 Nov 2018 Andres Karjus, Richard A. Blythe, Simon Kirby, Kenny Smith

Newberry et al. (Detecting evolutionary forces in language change, Nature 551, 2017) tackle an important but difficult problem in linguistics, the testing of selective theories of language change against a null model of drift.

Quantifying the dynamics of topical fluctuations in language

1 code implementation2 Jun 2018 Andres Karjus, Richard A. Blythe, Simon Kirby, Kenny Smith

In this work, we introduce a simple model for controlling for topical fluctuations in corpora - the topical-cultural advection model - and demonstrate how it provides a robust baseline of variability in word frequency changes over time.
