摘要	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 Modern NER systems are trained on clean contemporary text, but historical documents arrive full of archaic and inconsistent spelling, obsolete place-names, OCR or handwriting-transcription errors, and entities that have since changed names or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 GIS brings the spatial-analytic power of geographic information systems to the study of the past, building databases in which historical places, boundaries, and phenomena are tied to coordinates and to the dates at which they held. Systematized in Ian Gregory and Paul Ell's foundational treatment, the approach addresses a problem ordinary GIS ignores: the geography of the past was not fixed. Administrative units split and merged, borders shifted, towns rose and vanished, so a historical GIS must represent geometry that changes through time. Researchers georeference old maps, digitize past boundaries, encode places in gazetteers, and link tabular historical data, censuses, tax rolls, trade figures, to these time-varying geographies. The result supports genuinely spatial questions: how phenomena were distributed, how patterns clustered or diffused, how distance and terrain shaped historical life. It operationalizes the Annales attention to geography as a force in history, letting scholars map and measure the spatial structures within which past societies acted.
