The Jubilee 2025 is expected to attract millions of pilgrims to Rome, generating an unprecedented volume of user-generated content (UGC) through social media and online reviews. Unlike traditional surveys, reviews provide unsolicited and continuous feedback on visitors’ experiences, though their heterogeneity demands automated analysis. This study applies topic modeling to reviews of Roman churches, comparing Latent Dirichlet Allocation (LDA) with BERTopic. While LDA identifies broad thematic categories, BERTopic leverages semantic embeddings for more fine-grained distinctions. The contribution is threefold: (i) the design of a modular pipeline for UGC semantic analysis, (ii) a systematic comparison of statistical and neural approaches, and (iii) the demonstration of their relevance for monitoring perceived quality in large public events. Findings highlight insights into pilgrims’ experiences and suggest a scalable framework to support urban policy and service management during the Jubilee and beyond.
