Crow Intelligence
Human cognition is remarkable. Language is its most visible trace — in texts, speeches, narratives, and the metaphors societies use to make sense of the world.
At Crow Intelligence, we study that trace. We use computational methods and cognitive science to understand how language shapes thought, how narratives drive decisions, and how technology is transforming both.
We believe in open inquiry, rigorous method, and the value of understanding ourselves more clearly.

Projects
The Wealth of Nations — 250th Anniversary Digital Edition
An interactive exploration of Adam Smith's 1776 masterwork. Topic modeling, named entity recognition, rhetorical metaphor analysis, and full-text search across all five books.
The Nagel Index — Public vs. Private Personality
Big Five personality analysis of political leaders, measuring the gap between their public speeches and private correspondence. Inspired by Thomas Nagel's essay on ruthlessness in public life.
Market Metaphors — Kindleberger Phases × Narrative Economics
Tracing the evolution of metaphorical language in 158,666 financial news headlines (2009–2020) across five crisis events, mapping metaphor domains to the Minsky–Kindleberger panic cycle.
Semantic Shifts in Presidential Rhetoric
Tracking how the meaning of political concepts like freedom, democracy, and war evolves across 250 years of American presidential discourse. Built with our open-source chronowords package — PPMI embeddings, Procrustes alignment, and NMF topic modeling.
Semantic Explorer — Interactive Co-occurrence Networks
Explore the semantic structure of classic texts through interactive ego networks. Type a seed word, click to expand, and trace how meaning propagates through Tolstoy, Plato, Adam Smith, Darwin, and more. Built with our open-source kenon package.
Open Source
chronowords
Detect semantic shifts over time in text corpora. Memory-efficient PPMI-based word embeddings via Count-Min Sketch, NMF topic modeling, and Procrustes alignment for tracking how word meanings evolve across time periods.
kenon
Construct semantic and co-occurrence networks from text using corpus-internal statistics. Lightweight graph construction through spaCy tokenization, skip-gram windows, and network backbone extraction — no neural models or external training data required.
corvus
A cookiecutter template for data science and text analysis projects. Pre-configured scaffold with uv, ruff, DVC, MLflow, Sphinx docs, and structured directories — eliminate manual setup and start analysing.
What We Do
We conduct original research and take on analysis commissions for organisations that need deep expertise in language, cognition, and data.
Our work is analytical and advisory. We specialise in the hard problems that come before and after the code — specification, evaluation, and interpretation. We help organisations think clearly about what to build, whether it is working, and what the results actually mean.
If your organisation is working on a problem that involves text, language, narrative, or the behaviour of AI systems, we would like to hear from you.
