Extracting citation relations from legacy publications: The work of Basque scholar Koldo Mitxelena

We present experimental steps in the computational processing of the contents of Mitxelena's publications, and of relationships they contain. The written work of Koldo Mitxelena (1915-1987), Basque Philologist, is split in 1,665 single publications (745 unique articles). We have extracted citations of Mitxelena's articles from two Basque scientific journals, and collected them as citation relations in a Wikibase (Inguma Wikibase), on the one hand, and we have worked with the mentions of persons in Mitxelena's own work, on the other hand. We have recorded the mentions of persons in their context, along with relationships involving the entities describing these persons in Wikidata, in the same Wikibase instance. We have also included the results in Wikidata (see Mitxelena's citations at Scholia), for what we have taken some decisions, which we will discuss in this presentation.
