1Aslanidi, M. ; Papadakis, I. ; Stefanidakis, M.: Name and title authorities in the music domain : alignment of UNIMARC authorities format with RDA.
In: Cataloging and classification quarterly. 56(2018) no.4, S.354-373.
Abstract: This article discusses and highlights alignment issues that arise between UNIMARC Authorities Format and Resource Description and Access (RDA) regarding the creation of name and title authorities for musical works and creators. More specifically, RDA, as an implementation of the FRAD model, is compared with the UNIMARC Authorities Format (Updates 2012 and 2016) in an effort to highlight various cases where the discovery of equivalent fields between the two standards is not obvious. The study is envisioned as a first step in an ongoing process of working with the UNIMARC community throughout RDA's advancement and progression regarding the entities [musical] Work and Names.

2Papadakis, I. ; Stefanidakis, M. ; Tzali, A.: Visualizing OPAC subject headings.
In: Library hi tech. 26(2008) no.1, S.19-23.
Abstract: Purpose - This paper aims at providing a robust, user-friendly and efficient navigation procedure in an online library catalog that is based on semantic information encapsulated within subject headings. Design/methodology/approach - The paper describes an interactive navigation procedure inside an online library catalog based on semantic information. The proposed approach is presented through a web-based, prototype application following the most recent trends of the semantic web such as AJAX technology and the web ontology language - OWL for encoding semantics. Findings - According to the proposed method, a GUI interface exposes the hierarchy of the subject headings employed within an OPAC, as well as all stated relations between such headings, as links that the user can follow, effectively traversing the ontology and formulating at the same time the actual query to the underlying OPAC. This act of interactive navigation through the library's assets aids searchers in accurately formulating their queries, by offering broader or narrower concepts for selection or indicating alternative or related concepts they might be initially unaware of. The augmented exposition of inter-relations between concepts provides multiple paths for information retrieval and enables searchers to fulfill their information needs in a faster, more efficient and intuitive manner. Practical implications - The paper includes implications for the development of modern, semantic web applications focused on the library domain. The novel approach of visualizing subject headings could be further extended to visualize a number of other conceptualizations of the library domain. Originality/value - This paper fulfils an identified need to take advantage of the "hidden knowledge" existing within the library domain but, for a number of reasons, is never exposed to the library users.
