The volume of published articles has grown exponentially, making research documentation considerably harder, even within a single archive of a scientific journal or a repository of educational resources. As such, we have developed and present in this paper a toolkit that can effectively process full-text manuscripts starting from their PDFs, extract topics, and provide correlations between manuscripts based on their common topics. The effectiveness of the toolkit is demonstrated by applying it to an extensive text collection, that of the ”Interaction Design and Architecture(s)” (IxD&A) journal’s full-text articles published between 2013 and 2024 (N = 450). Topic modeling was performed using BERTopic and Llama as LLM to generate coherent topics. Introduced as a modern substitute for Latent Dirichlet Allocation, BERTopic effectively identifies topics using Transformerbased models and other clustering and dimensionality reduction methods such as HDBSCAN and UMAP. As a result, we extracted 246 topics from the entire corpus, which were automatically filtered for specificity using Llama-3.1. Indepth visualizations and analyses covering the main topics and their evolution in time following the technological advances, but maintaining a focus on a humancentered, smart learning perspective, are presented. We release our toolkit as open-source on GitHub to enable users to easily apply our method to other journals, repositories of educational materials, and in other relevant contexts. In addition, we have integrated the generated views into the IxD&A journal webpage – https://ixdea.org/background-toi/- to enable the fruition of the outcomes produced by our toolkit to end users – in our case, the readers of IxD&A journal.
