Word occurrence based extraction of work contributors from statements of responsibility
International Journal on Digital Libraries, 2014Co-Authors: Nuno FreireAbstract:This paper addresses the identification of all contributors of an intellectual work, when they are recorded in bibliographic data but in unstructured form. National Bibliographies are very reliable on representing the first author of a work; however, secondary contributors are frequently represented only in the statements of responsibility that are transcribed by the cataloguer from the book into the bibliographic records. The identification of work contributors mentioned in statements of responsibility is a typical motivation for the application of information extraction techniques. This paper presents an approach developed for the specific application scenario of the ARROW rights infrastructure being deployed in several European countries to assist in the determination of the copyright status of works that may not be under public domain. An evaluation of our approach was performed in catalogues of nine European National libraries of countries that are available in the ARROW rights infrastructure, which cover eight different languages. The evaluation has shown that it performs reliably across languages and bibliographic datasets. It achieved an overall precision of 98.7 % and recall of 96.7 %.

a system for using National Bibliographies in rights information infrastructures
International Conference on Asian Digital Libraries, 2011Co-Authors: Nuno Freire, Andreas JuffingerAbstract:In the process of digitising a book, a library needs to clear the rights associated with it. Rights clearance is largely a manual, time-consuming process which possibly costs more than the actual digitisation. To analyse the rights situation, a range of information is required, which is distributed across several National databases hosted in National libraries, publishers and collective rights organisations. National Bibliographies are a key data source in these processes, as they are the only source to identify all the publications of a specific intellectual work in a country. However, National Bibliographies are not designed and built to support rights clearance purposes. The information in bibliographic records results from cataloguing with users and library management in mind, and links between different publications of a single intellectual work are not available. This paper presents a system implemented in The European Library to integrate National Bibliographies into the ARROW (Accessible Registries of Rights Information and Orphan Works) rights information infrastructure. The system makes it possible to identify all different publications with a common underlying intellectual work. This system forms the main source of bibliographic metadata due to the fact that The European Library is an aggregator of all Europe's National library catalogues.

using National Bibliographies for rights clearance
ACM IEEE Joint Conference on Digital Libraries, 2011Co-Authors: Nuno Freire, Andreas JuffingerAbstract:In the process of digitizing a book, a library needs to clear the rights associated with it. Rights clearance is a time consuming process, and possibly, with higher costs than the actual digitization. To analyze the rights situation, a range of information is required, which is distributed across several National databases hosted in National libraries, publishers and collective rights organizations. National Bibliographies are key data sources in these processes, as they are the only source to identify all the publications of a specific intellectual work per country. However, National Bibliographies are not built for rights clearance purposes. The information in bibliographic records results from cataloguing practices with users and library management in mind, and links between different publications of a single intellectual work are not available. This paper presents a study on the implications of data quality problems of National Bibliographies for the identification of all publications of a work. It also presents an approach for work data extraction and matching based on similarity of the most discriminatory attributes of works. Evaluation has shown that the data quality problems are difficult to overcome, as our best approach achieved an F0,5-measure of 0,91. These results help to speed up the process of discovering all relevant publications per work significantly, with sufficient recall.

Frbrisation: Towards a Bright New Future for National Bibliographies
International cataloguing and bibliographic control, 2009Co-Authors: Jan Pisanski, Maja Žumer, Trond AalbergAbstract:The Functional Requirements for Bibliographic Records (FRBR) conceptual model is beginning to gain recognition. This paper presents FRBR including possibilities and limitations of current standards and practices in terms of expressing the FRBR model. It is claimed that National Bibliographies should benefit the most from FRBR, as they contain large quantities of high quality bibliographic data on many works with multiple versions. The paper is in part based on the results of frbrisation of the Slovenian National bibliography and of two other bibliographic databases.

the new guidelines for National Bibliographies in the digital age
2007Co-Authors: Maja ŽumerAbstract:The Working group on Guidelines for (electronic) National Bibliographies was established in 2004 has started the work with an analysis of users and contexts of use of National Bibliographies (NB) in the digital age. National Bibliographies are changing dramatically: they include more and more also bibliographic records for digital resources and National bibliographic agencies are increasingly complementing (or even replacing) printed versions of NB with electronic. The guidelines will be soon posted for teh world-wide review; this paper gives and overview of the document prepared so far.

Guidelines for electronic National Bibliographies: Are they needed?
International cataloguing and bibliographic control, 2004Co-Authors: Maja ŽumerAbstract:Electronic National Bibliographies (ENB) (online and on CD-ROM) have been around since the late 80's. They differ substantially regarding the functions supported, access points and indexes, and the user interface. One of the results of the European 'National Libraries Project on CD-ROM' in 1993 was the first example of guidelines for ENB. While partly outdated now due to development of computer hardware and software, they could still serve as a good starting point for new guidelines which are needed both for development of existing ENB and planning of new ones. The need for, and areas of, new guidelines for ENB are discussed.

Changes in National Bibliographies, 1996–2000
Alexandria: The Journal of National and International Library and Information Issues, 2002Co-Authors: Unni KnutsenAbstract:A survey on National Bibliographies was carried out among member countries of the Conference of Directors of National Libraries in 2001, as a follow up to Holley's 1996 survey. All parts of the world are represented among the 52 responses. The main findings are that legal deposit legislation still emphasizes textual material. Many agencies are currently revising their legislation to include more types of material, in particular electronic documents. Print remains the preferred format for National Bibliographies but more and more agencies are offering Internet access. More than half of the agencies are currently undertaking or planning retrospective conversion programmes.
