Na era da informação e da tecnologia, a criação de thesauri assumiu uma relevância preponderante no sentido de criar linguagens próprias de indexação e catalogação do património cultural, criando pontes entre instituições, profissionais de áreas variadas e público em geral. A complexidade da sua organização acarreta desafios, tanto maiores quanto a respectiva abrangência temática e as línguas envolvidas. O AAT-Art & Architeture Thesaurus, surgiu, nesta perspectiva, como modelo a seguir na realidade cultural portuguesa, tendo sido alvo de análise profunda no sentido de ser adaptado ao caso de estudo que aqui se apresenta.

The African Studies Centre (ASC) Leiden is an independent foundation associated with Leiden University. Its aims are to undertake research on Africa in the social sciences, to maintain a specialist library and documentation department, and to facilitate the dissemination of information on Africa. The library houses a broad-based collection in the field of the social sciences and the humanities, the only collection in the Netherlands focusing entirely on Africa. Current holdings include some 75,000 books, 2,000 periodicals, of which almost 600 are current subscriptions, about 1,000 documentaries and feature films, and a growing digital collection. Approximately half the holdings are English, about a third French, and the remainder is divided between German, Dutch, Afrikaans, Portuguese and Spanish. Between 2000 and 2006, the library carried out a project to improve subject access to the ASC collection by building an African Studies Thesaurus and converting all subject codes used until then into thesaurus descriptors.

The paper explores two possible solutions for integrating a thesaurus and a classification scheme, specifically UDC, in order to develop a common platform for subject information retrieval through both systems. The author reports and compares experiences from two Hungarian projects aimed at creating a complex system for combining UDC and thesauri under a homogeneous theoretical framework: MÁTrIkSz (Hungarian Comprehensive Information Retrieval Language Dictionary) and the project of thesaurus construction and implementation in the Hungarian National Library (Széchényi). The role of UDC in these two projects is analyzed with respect to the features supported, classification-based retrieval functionalities, and the perceived advantages in subject access and knowledge organization. The author explains the methodology of her research based on an examination of structured and well-documented examples and literature research into the theory of UDC and its use. The paper underlines the importance of cognition as the basis for concept-building and points out some possibilities and expedients for the integration of thesauri and the UDC.
