Recuperando e Tornando Reusáveis e Interoperáveis Tesauros Brasileiros de Cultura e Ciência em Formato Textual

Several Brazilian thesauri in fields such as Culture and Memory have become "orphans" or "zombies" following the discontinuation of their original projects. Often available only in unstructured formats (PDF) or closed platforms, these vocabularies face significant barriers to reuse and interoperability. This research proposes technological solutions to make such resources migratable and integrable into new systems. The methodology, exploratory and applied, utilizes the TemaTres software to convert textual formats into SKOS. The initial experiment involved importing the CAPES/CNPq Table of Knowledge Areas and the Brazilian Thesaurus of Information Science. Results confirm the feasibility of transforming these Knowledge Organization Systems (KOS) into machine-processable formats, despite technical challenges in data extraction. The study discusses the relevance of these vocabularies for the Semantic Web and Big Data, while also addressing public policy and copyright issues. With the successful export to SKOS, the analyzed thesauri are now fully reusable, demonstrating a viable path for the preservation and evolution of Brazilian informational and scientific heritage.
