Chronological Corpora Curve Clustering
Analyze the temporal evolution of concepts and semantic trajectories in scientific corpora through advanced statistical modeling and clustering.
Powerful Tools for Temporal Corpus Analysis
📥 Data Import & Preprocessing
Import term-document matrices, clean data, and automatically classify terms into frequency zones for stratified analysis.
📊 Flexible Normalization
Multiple normalization methods (nc, nchi, nM, nmM, nnl) to account for corpus size variations and enable fair temporal comparisons.
📈 Temporal Modeling
Model term life-cycles using B-spline smoothing with cross-validated parameter selection for optimal trajectory estimation.
🧩 Trajectory Clustering
Cluster terms with similar temporal patterns to identify conceptual convergence, divergence, and knowledge dynamics.
🔍 Rich Visualization
Publication-ready plots including temporal curves, faceted visualizations, and zone-based comparisons with customizable themes.
⚙️ Statistical Rigor
Grounded in temporal scientometrics with GCV/OCV criteria for parameter selection and diagnostic validation tools.
