1Manguinhas, H. ; Freire, N. ; Machado, J. ; Borbinha, J.: Supporting multilingual bibliographic resource discovery with Functional Requirements for Bibliographic Records.
In: Semantic Web journal. 3(2012) no.1, S.3-21.
Abstract: This paper describes an experiment exploring the hypothesis that innovative application of the Functional Require-ments for Bibliographic Records (FRBR) principles can complement traditional bibliographic resource discovery systems in order to improve the user experience. A specialized service was implemented that, when given a plain list of results from a regular online catalogue, was able to process, enrich and present that list in a more relevant way for the user. This service pre-processes the records of a traditional online catalogue in order to build a semantic structure following the FRBR model. The service also explores web search features that have been revolutionizing the way users conceptualize resource discovery, such as relevance ranking and metasearching. This work was developed in the context of the TELPlus project. We processed nearly one hundred thousand bibliographic and authority records, in multiple languages, and originating from twelve European na-tional libraries. This paper describes the architecture of the service and the main challenges faced, especially concerning the extraction and linking of the relevant FRBR entities from the bibliographic metadata produced by the libraries. The service was evaluated by end users, who filled out a questionnaire after using a traditional online catalogue and the new service, both with the same bibliographic collection. The analysis of the results supports the hypothesis that FRBR can be implemented for re-source discovery in a non-intrusive way, reusing the data of any existing traditional bibliographic system.

2Borbinha, J.: Authority control in the world of metadata.
In: Cataloging and classification quarterly. 38(2004) nos.3/4, S.xx-xx.
Abstract: This paper discusses the concept of "metadata" in the scope of the "digital library," two terms recently used in a great diversity of perspectives. It is not the intent to promote privilege of any particular view, but rather to help provide a better understanding of these multiple perspectives. The paper starts with a discussion of the concept of digital library, followed by an analysis of the concept of metadata. It continues with a discussion about the relationship of this concept with technology, services, and scenarios of application. The concluding remarks stress the three main arguments assumed for the relevance of the concept of metadata: the growing number of heterogeneous genres of information resources, the new emerging scenarios for interoperability, and issues related to the cost and complexity of current technology.

3Borbinha, J.L. ; Freire, N.: Deposit collections of digital theses and dissertations.
In: Zeitschrift für Bibliothekswesen und Bibliographie. 48(2001) H.3/4, S.217-224.
Abstract: The Portuguese legal deposit law requests the deposit of theses and dissertations in the National library. The actual law is concerned only with printed material, but the National library has been defining a strategy to address also the problem of the deposit of digital publications. These efforts are concentrated in three main components: an overall analysis of the structure of the problem; the development of the concept of publication genre; and the development of the concept of deposit by scenarios. In this context, the deposit of theses and dissertations emerged as an ideal case study for a scenario concerned with a specific genre, which deserves to be addressed not only as a purpose in itself, but also as an experiment from which we expect to learn valuable lessons for the overall problem
