Eliminating query failures in a work-centric library meta-search environment
(2009)
Purpose - This paper aims to describe how approaches such as semantic based query rewritings and FRBR work entities composition could solve existing problems and improve the overall behavior of a mediated based meta-search ...
Semantic based substitution of unsupported access points in the library meta-search environments
(2008)
Meta-searching library communities involve access to sources where metadata are invisible behind query interfaces. Many of the query interfaces utilize predefined abstract Access Points for the implementation of the search ...
Expression of Z39.50 supported search capabilities by applying formal descriptions
(2005)
The wide adoption of the Z39.50 protocol from the Libraries exposes their abilities to participate in a distributed environment. In spite of the protocol specification of a unified global access mechanism, query failures ...
A semantics-based graph for the Bib-1 Access Points of the Z39.50 protocol
(1996)
A graph of Access Points can be used as a tool in a number of applications such as, clarification and better understanding of their semantics and inter-relations, query transformations, more precise query formulation, etc. ...
Meta-composer: synthesizing online FRBR works from library resources
(2010)
Next generation display and indexing of cataloging records are mainly influenced from the development of the FRBR conceptual model. While the process for collecting all relevant bibliographic records in a catalogue to an ...
A semantics-based substitution for unsupported Z39.50 Bib-1 access points
(2007)
Unsupported Z39.50 Access Points result to query failures and/or inconsistent answers, in spite of the protocol specification for a unified global access mechanism. A challenge to this issue is to substitute an unsupported ...
FRBRization: using UNIMARC link fields to identify Works
(2011)
The main objective of this study is to amalgamate the MARC 21 FRBRization practices with UNIMARC format semantics and to highlight some differences between them in the context of FRBRization. The main focus is to examine ...
An architecture for online information integration on concurrent resource access on a Z39.50 environment
(2003)
The lack of information integration, by the existing online systems, for resource sharing in a distributed environment, impacts directly to the development and the usage of dynamically defined Virtual Union Catalogues. In ...
Mining user communities in digital libraries
(2010)
The interest in the analysis of library user behaviour has been increasing rapidly since the advent of digital libraries and the Internet. In this context, the authors analyze the queries posed to a digital library and ...
