%description
Provides a 'Shiny' graphical interface for the complete workflow of Latent
Dirichlet Allocation (LDA) topic modelling on bibliometric data from
Scopus and Web of Science. Steps include data import and deduplication,
text preprocessing (stopword removal, stemming, n-grams, sparse-term
filtering), statistical inference to select the optimal number of topics
via coherence, final model training, and topic trend analysis over time
using linear regression. All results can be exported as Excel files, RDS
objects, and publication-quality plots.
