Decidim Barcelona Proposal Topics 2016-2024
📊 Exploring the top 20 emerging topics from 31,775 citizen proposals in decidim.barcelona, with topic modelling (BERTopic) and deicdim-based open data.
31,775 proposal descriptions from decidim.barcelona (2016-2024), iterating through various parameters and data cleaning techniques, to extract 20 clearly recurrent topics emerging across 270 participatory processes.
Sentence embeddings generated using the HuggingFace sentence-transformers library and the public Catalan fine-tuned language model projecte-aina/ST-NLI-ca_paraphrase-multilingual-mpnet-base, from ProjecteAINA, published by the Barcelona Supercomputing Center.
Topics modelled using BERTopic pipeline (UMAP dimensionality reduction, HDBSCAN clustering, and c-TF-IDF topic representation).
