It provides a comprehensive end-to-end workflow, allowing users to train models with full hyperparameter control, enrich topics with LLM-generated labels, and evaluate results using an interactive dashboard rich with visualizations and metrics. Additionally, TOVA offers robust features for running inference on new documents, built-in uncertainty quantification to estimate document-topic probabilities, and a flexible plug-in architecture that makes it easy to integrate new model classes.", "distribution": [{"accessURL": "https://github.com/usnistgov/TOVA", "description": "NIST GitHub repository for TOVA", "format": "code repo", "title": "TOVA.git"}, {"description": "Describes purpose of TOVA, functionality, setup and configuration, and troubleshooting", "downloadURL": "https://data.nist.gov/od/ds/mds2-4134/readme.md", "format": "markdown", "mediaType": "text/markdown", "title": "README"}], "identifier": "ark:/88434/mds2-4134", "issued": "2026-07-29", "keyword": ["artificial intelligence", "content analysis", "grounded theory", "large language model", "natural language processing", "topic model", "unstructured text"], "landingPage": "https://data.nist.gov/od/id/mds2-4134", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2026-06-10 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["https://doi.org/10.18653/v1/2024.eacl-long.51", "https://doi.org/10.18653/v1/2025.acl-long.375"], "theme": ["Information Technology:Computational science", "Information Technology:Software research"], "title": "TOVA: Topic Visualization & Analysis"}
