Computational History and Digital Humanities apply intelligent computing to analyze cultural artifacts, historical documents, and human narratives at unprecedented scale and detail. Machine learning extracts patterns from texts, images, maps, and audiovisual materials. Large-scale corpus analysis reveals social networks, ideological trends, migration patterns, and linguistic evolution. Digital reconstruction restores damaged manuscripts, artifacts, and heritage structures. Interdisciplinary collaboration merges history, archaeology, linguistics, art history, anthropology, and data science. Visualization tools create interactive historical timelines and cultural atlases. Computational methods support hypothesis testing, reinterpretation of historical narratives, and discovery of previously hidden insights. This field enriches humanities research and makes cultural knowledge more accessible worldwide.
