Case study for the management of a set of spectrally analyzed signals based on OODBMS
(1997)This paper is a case study for the management of a set of synthetic harmonic and real-world sampled signals analyzed by various spectral methods at some desired orders. An OODBMS schema was preferred to an alternative ... -
A Compressed Self-indexed Representation of XML Documents
(2009)This paper presents a structure we call XML Wavelet Tree (XWT) to represent any XML document in a compressed and self-indexed form. Therefore, any query or procedure that could be performed over the original document can ... -
Considerations On Low Complexity Codes Concerning Symmetry And Cyclicity
The binary error correcting codes that are examined in this paper are codes which are constructed out of shorter subcodes. The method of construction is well described by a bipartite graph. The one set of nodes of this ... -
Developing and supporting open access policies in research institutions: why, how and who!
(Κυπριακή Ένωση Βιβλιοθηκονόμων - Επιστημόνων Πληροφόρησης, 2015) -
Dimensionality Curse, Concentration Phenomenon and the KDB-tree
(2011)The problem of indexing large volumes of high dimensional data is an important and popular issue in the area of database management. There are many indexing methods that behave well in low dimensional spaces, but, in high ... -
A Hybrid Distributed Architecture for Indexing
(2009)This paper presents a hybrid scavenger grid as an underlying hardware architecture for search services within digital libraries. The hybrid scavenger grid consists of both dedicated servers and dynamic resources in the ... -
Improving Information Retrieval Effectiveness in Peer-to-Peer Networks through Query Piggybacking
(2009)This work describes an algorithm which aims at increasing the quantity of relevant documents retrieved from a Peer-To-Peer (P2P) network. The algorithm is based on a statistical model used for ranking documents, peers and ... -
Improving Query Efficiency in High Dimensional Point Indexes
(2011)In this paper, we focus on the leaf level nodes of tree-like k-dimensional indexes that store the data entries, since those nodes represent the majority of the nodes in the index. We propose a generic node splitting approach ... -

Mapping Derivative Relationships from RDA to BIBFRAME 2
(2019)Semantic interoperability between Resource Description and Access (RDA) and BIBFRAME models is of great interest to the library community. In this context, this work investigates the mapping of core entities, inherent and ... -
Methodology of analysis and interrelation of data about quality indexes of library services by using data- and knowledge- mining techniques
(2009)Purpose - This paper aims to describe a data analysis methodology using data- and knowledge-mining techniques focused on libraries. It concerns data analysis techniques in general, as well as ways in which they could be ... -
Name and Title Authorities in the Music Domain: alignment of UNIMARC Authorities Format with RDA
(2017)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 ... -
On rewriting Xpath Queries Using Views
(2009)The problem of rewriting a query using a materialized view is studied for a well known fragment of XPath that includes the following three constructs: wildcards, descendant edges and branches. In earlier work, determining ... -
On solving efficiently the view selection problem under bag-semantics
(2009)In this paper, we investigate the problem of view selection for workloads of conjunctive queries under bag semantics. In particular we aim to limit the search space of candidate viewsets. In that respect we start delineating ... -
Optimal Support for Information Seeking Strategies by Adapting the User Interface
(2009)To satisfy their information needs, information searchers employ a host of search actions, that fall into different classes. Whereas most current IR systems only support one or very few of these actions well, we aim at the ... -
Representing and integrating bibliographic information into the Semantic Web: a comparison of four conceptual models
(2017)Integration of library data into the Semantic Web environment is a key issue for libraries and is approached on the basis of interoperability between conceptual models. Several data models exist for the representation and ... -

Results from a study of the implementation of metadata application profiles in Agricultural Learning Repositories
(2008)In technology-enhanced learning, metadata interoperability has been identified as an important issue. It allows not only the exchange and preservation of crucial learning and teaching information (such as competency ... -
Storing multidimensional XML documents in relational databases
(2007)The problem of storing and querying XML data using relational databases has been considered a lot and many techniques have been developed. MXML is an extension of XML suitable for representing data that assume different ...
