Off-the-shelf NER handles the poem poorly because of its dense mix of historical and mythological names, Latin-influenced syntax and the irregular spelling of the 1572 edition. Within the "Lusíadas Digital" project, the authors design a TEI P5 model. It encodes persons with \ (typed as historical or mythological), places with \ (real or mythical), and epithets and antonomasia with \ linked through @ref. They process both the 1572 edition and a modernized Project Gutenberg text with a Python pipeline: an authority gazetteer, spaCy NER, and a regex routine that rejoins names split by line-break tags. Manual philological post-editing follows. spaCy, trained on news text, confuses deities with places, treats capitalized common nouns as persons and misses epithets, so the gazetteer and human curation proved more dependable. The resulting linked TEI edition enables entity-level queries, future social network analysis and digital mapping of the voyages. ## Key points - The pipeline has three stages: a gazetteer for frequent, unambiguous entities; spaCy `pt_core_news_lg` for uncatalogued names; and regex protection of names split by `` (e.g. Lusi\tana) in the 1572 text. - The two inputs are the 1572 edition, which keeps archaic spelling plus `` and `` markup, and the normalized Project Gutenberg edition. - Observed errors include Marte tagged as a location, "Fama" and "Mar" tagged as persons, and epithets like "o grão Macedônio" ignored. - In the "Lampetusa" (I, 46) case, NER suggests the island, while the curated encoding links it to the Heliades. This draws on the dictionaries of Peixoto & Pinto (1924) and Nogueira (1960) and on Silva Dias's commentary. - The `` holds a prosopography and a gazetteer with unique `xml:id`s, so variants such as "Lusitana" and "Lusa" resolve to `#portugal`. No quantitative evaluation scores are reported. *Our summary of the paper, in our own words — not its text.
