Резюме	Historical named-entity recognition adapts a core natural-language-processing task, identifying and classifying the names of persons, places, organizations, and dates in text, to the distinctive difficulties of historical sources. Modern NER systems are trained on clean contemporary text, but historical documents arrive full of archaic and inconsistent spelling, obsolete place-names, OCR or handwriting-transcription errors, and entities that have since changed names or vanished. Work surveyed by Seaward and colleagues addresses these obstacles, combining machine-learning sequence models with historical gazetteers and authority files to recognize entities reliably in noisy diachronic text. The payoff is large: once persons, places, and dates are extracted and linked to standard identifiers, historians can build prosopographies of who appears with whom, populate historical GIS with mapped place-names, and structure vast textual archives for search and analysis. Historical NER thus serves as a crucial bridge, turning the unstructured output of digitization and text mining into structured, linkable data about the actors and settings of the past.	Historical corpus text mining applies computational methods to thousands or millions of historical documents at once, seeking macro-scale patterns that close reading of individual texts could never reveal. Associated above all with Franco Moretti's program of distant reading, the approach treats large bodies of text, newspapers, parliamentary records, novels, correspondence, as data to be measured rather than works to be interpreted one by one. By counting word frequencies, computing weighted term importance, fitting topic models, and tracking how vocabulary shifts across decades, researchers can chart the rise and fall of concepts, the diffusion of ideas, and the changing texture of public discourse over long spans. The method is explicitly quantitative and aggregative: its claims concern populations of documents, not exemplary passages. Adapting modern natural-language processing to historical material, however, requires confronting archaic spelling, OCR noise, and shifting word meanings. Done carefully, corpus text mining turns vast unread archives into evidence about how language, and the thought it carries, evolved historically.
