Towards a Brazilian History Knowledge Graph
This work addresses the need for structured repositories of Brazilian historical entities to aid information extraction from Portuguese texts, but it is incremental as it describes initial steps and outlines future construction.
The paper tackles the problem of constructing a knowledge graph for Brazilian history by integrating data from the Brazilian Dictionary of Historical Biographies (DHBB) and Wikipedia/Wikidata, revealing that many DHBB entities lack corresponding entries in Wikidata.
This short paper describes the first steps in a project to construct a knowledge graph for Brazilian history based on the Brazilian Dictionary of Historical Biographies (DHBB) and Wikipedia/Wikidata. We contend that large repositories of Brazilian-named entities (people, places, organizations, and political events and movements) would be beneficial for extracting information from Portuguese texts. We show that many of the terms/entities described in the DHBB do not have corresponding concepts (or Q items) in Wikidata, the largest structured database of entities associated with Wikipedia. We describe previous work on extracting information from the DHBB and outline the steps to construct a Wikidata-based historical knowledge graph.
