Natural Language Processing

Overview

This project applies computational text analysis to the study of international relations and climate security. The main motivations are twofold: (1) to detect latent patterns in large bodies of academic and policy texts that are not accessible to conventional close-reading methods, and (2) to build open tools that lower the technical barrier for IR researchers to use NLP methods.

Word2Vec Model Explorer

The Word2Vec Model Explorer is a browser-based interface for exploring word embeddings trained on a corpus of climate security academic literature. It allows researchers to query nearest neighbours (semantically similar terms), visualise vector arithmetic (e.g. "conflict + climate minus development"), and inspect semantic clusters across the corpus.

The model was trained using the word2vec skip-gram architecture on a curated collection of peer-reviewed articles on climate security and related topics. The explorer runs entirely in the browser with no server-side processing, making it fast to deploy and easy to share.

cntrlfinder

The cntrlfinder toolkit is a Python-based utility for systematic content analysis of policy documents and academic texts. It automates common preprocessing steps (tokenisation, stopword removal, n-gram extraction) and provides frequency and co-occurrence analysis tailored to IR and policy research contexts.

Discourse Analyses

Corpus analysis of institutional and media texts to map how policy actors construct and contest climate-related issues:
