Title Evaluation implementation of "The European Library"
Creator Giannoulakis, Stamatios
Date 2007
Abstract Recently, digital libraries have increasingly developed and they play an important role in library and information science field. Through digital libraries, the user can search and retrieve information and content that was hidden before. Last years, along with libraries development, there are important steps in digital libraries evaluation. This master thesis' main goral is to implement evaluation on "The European Library". This survey requested librarians and archrivists to evaluate the "The European Library", which compromise an effort for offering access to European national libraries. The survey results revealed important issues and weaknesses of "The European Library". These results will help both, "The European Library" and the research, in improving digital libraries evaluation.

Title Technology Acceptance Model: A case study on Library Web pages
Creator Zarvala, Harikleia
Date 2006
Abstract Technology Acceptance Model is a quite widespread model that predicts and explains the use of information systems. This Thesis makes an effort to apply this model in library information systems, specifically in library web pages, with the addition of external variables that concern with the degree of users familiarization to web applications, their interaction with the system and the quality of the provided information. For this purpose, a questionnaire was prepared and an experiment was held with postgraduate students of Department of Archival and Library Sciences. Despite the small and special sample, Technology Acceptance Model appears to be a tool which can correspond to the interpretation and prediction of information services use.

Title Semantic mapping between SCORM and MPEG7 concepts
Creator Vagiati, Barbara
Date 2006
Abstract In this study it is presented a model for the interoperability among different metadata standards and more specific between MPEG-7 and SCORM. This model concerns first of all the semantic mapping between the different metadata of these standards. The MPEG-7 provides a standardized set of technologies for describing multimedia content. SCORM is a collection of specifications for developing, organizing and delivering instructional content. However, the developing of these standards according to the specific requirements of their communities may cause problems of interoperability between audiovisual digital libraries and eLearning implementations. So, it is necessary the development of a model that will allow the use of semantic descriptions of audiovisual content objects and/or segments that reside on a digital library in order to support the creation of reusable learning objects that may be used in the assembly of personalized courses. The semantic mapping between MPEG-7 & LOM and MPEG-7 & SCORM cp standards is presented through an ontology (SCORM_MPEG7_Ontology), that captures the common elements and attributes of these metadata standards. With this ontology it is represented the detailed mappings of the elements and attributes and their relations of the metadata standards. For the implementation of this task it has been used GraphOnto.

Title Developing a digital library by using manuscripts of Nikos Kitsikis: digitization, selection and use of a metadata standard, selection and use of a software application in order to develop a digital library
Creator Kantarelis, Spyridon
Date 2006
Abstract We are living in a society which is known as "information society". This qualification implies the importance of information for modern people and their civilization. The management and utilization of information, supported by the use of computers and telecommunication networks. The development that has taken place in these technological fields, has rendered the management and utilization of information much more improved, providing the capability of access to all users that dispose the appropriate equipment and simultaneously, satisfying their information needs. In the present thesis is being made an effort to utilize these technologies in order to manage manuscripts, which are part of the personal correspondence of Nikos Kitsikis. Through a specific application, the manuscripts have been organized in a digital collection and thus a digital library has been created, providing information to all interested users, irrelevantly of the natural distance that separates them from the documents.

Title Dublin core and common application profiles for libraries
Creator Christianoudis, Ioannis
Date 2006
Abstract One of the most significant components of the "Information Society" are all kinds of libraries, documentation centers and informational services. One characteristic tool and model that libraries use in order to describe and organize their collections and information in general, is the Dublin Core Template. The Dublin Core is a metadata template for the description of the sources and it also covers not only bibliographic data, but broader data categories as well. Because of the rapidly increasing amount of information and owing to the complexity and the specialization of the new data, it was necessary to create the Application profiles. The Application profiles combine and mix different metadata schemas with Dublin Core Metadata Initiative. This aims at importing discriptive elements, that may not be included in a metadata schema, for a better and more complete description of new and more specialized data. In the present thesis, we present and note down the research that has been done, concerning the already existing application profiles and those that have been developing for the libraries. But mainly, there is an endeavor to fing application profiles that cover sectors and services of a library, regarding to everything else but the book.

Title Review and comparison of the most widely used open-source software for digital libraries
Creator Giouli, Charikleia
Date 2005
Abstract In recent years the use of digital media and related technologies has led to the enormous increase of digital material in transit. This fact as well as the noted incapability of handling this amount of data without the use of information technology, resulted in the creation of digital libraries. The latter employ tools and methods from the information technology domain, especially the so-called open-source software, which has evolved into a de-facto and strategic solution. This project work presents and analyses ten (10) open-source software solutions for digital libraries, in an attempt to provide the reader with objective comparative data and to guide him, to a reasonable extent, in choosing the right product for his/her intended use.

Title Distance education policies for Academic Libraries in Europe
Creator Kokkinos, Dionysios
Date 2005
Abstract The integration of the Information and Communication Technologies (ICT) has changed significantly the field of education. Due to the adoption of the new technologies, e-learning has been emerged and developed. As a result, distance learning has transformed and new possibilities have appeared. It is remarkable that distance learning became and considered as a scout of the new era in education and contributed to the quality of education. Higher institutions, colleges and universities play an important role in offering education and consequently they reacted by designing and delivering distance learning courses. Simultaneously, libraries tend to adapt their services in order to meet different needs of various user groups. In the present thesis we are trying to present the new educational environment and how has it changed because of the open and distance education. Main subject of the thesis is not only to present the policies used by academic libraries in Europe, but also to record the general European educational policy context. In addition, it is attempted to present the Greek case and afterwards the role of the library in the new educational environment. Libraries have to cope with new challenges and they have to fulfill new and various needs.

Title The role of libraries in lifelong learning
Creator Balatzaras, Marios
Date 2005
Abstract In our days the world is defined by quick structural changes and developments in the fields of economics, technology and society. These changes reform our society in what is called today society or the economy of knowledge. In this way it is made necessary more so than less for individuals to acquire knowledge and qualifications or skills, whose duration but their variety also will allow them to adapt in these changes. Simultaneously the political and educational framework changes and adapts according to the commands of globalization and the knowledge of the global economy. For the creation of effective systems of lifelong education the different countries are moving towards some very important changes so much so in the administration as well as in the funding of the educational systems and its formation. At the same time libraries, nowadays, by using these new technologies of information and communication are reorganized and change their functioning role. Also their role in life-long learning is a matter which is causing a lot of talk. In the bibliography it is mainly shown as a provider of access and supporter of knowledge, but their also exist situations in which the libraries manage or the library itself becomes the creator of subject matter towards life-long study. The research part of this project is to register through political text and positioning the role of the library in lifelong learning, mainly in countries, which are considered pioneers and innovators in matters of the library but in Greece as well. There is made a registration of the meanings which are related with life-long learning and the current role of the library in life-long learning is examined with an emphasis in new technologies such as e-learning. Finally an attempt is made at imprinting the trends of evolution of life-long learning and the role of the library in this field, while conclusions and suggestions are brought forward.

Title Friendly use of ontologies / thesauri from information systems / digital libraries
Creator Brindesi, Charikleia
Date 2005
Abstract The continuous incorporation of digital type of material in the collections of the libraries as well as the ongoing advances in new technologies have brought about the need for the libraries to use post-coordinated systems, mainly thesauri. However, a significant problem exists in connection with the exploitation of the full potential that thesauri could provide nowadays. The majority of the Integrated Library Systems (ILS), which have become an integral part of helping libraries manage their collections, have not incorporated thesaurus supporting subsystems; furthermore, the remaining minority that includes such subsystems can not provide satisfactory results. On the other hand, although the Thesaurus Management Systems (TMS) provide great facilities for both the input of data and information retrieval, they can only be used as independent systems. The solution to this problem seems to be the finding of a modus that would permit TMS and ILS to operate integrated. The present essay provides a list of "proposals - requirements" which are necessary for the creation of the specifications required for a properly created integration. This list reflects a purely librarian's point of view. For the construction of the list in question, all kinds of users as well as indexers were taken in to consideration.

Title Detection of duplicate bibliographic resources or records in electronic descriptions
Creator Sitas, Anestis
Date 2005
Abstract In the last 25 years, as the size and the number of bibliographic databases continuously increase, libraries have to deal with the pressing issue of duplicate bibliographic records. Databases are rapidly enriched and the situation is aggravated since along with the number of bibliographic records the number of users increases as well. In individual databases, the problem becomes more obvious when data are prepared for migration to a more technologically advanced system. Usually, however, the problem comes to light when union catalogs are developed and records from multiple independent systems are merged in one system or cooperative cataloging systems are being developed in a network environment. The paper examines and categorizes all possible approaches for the identification of duplicate records according to the applied procedures. We report how algorithms are used to detect duplicate records, and their efficiency as well. Also, we examine the processes of clustering equivalent or related manifestations of bibliographic records. Our analysis concludes that the application of algorithms to detect duplicate records constitutes an integrated process or a two-step consecutive process. We note that the ultimate goal of all the above processes is the deletion, merging or the temporary and virtual consolidation of duplicate records. Finally, we examine issues regarding the operation of real and virtual union catalogs and the protocol's Z39.50 services to cope with the problem of duplicate records.

Title Personal data processing and protection of privacy in the new frame of libraries and information services
Creator Strakantouna, Vasiliki
Date 2005
Abstract The integration of the new Information and Communication technologies in the work performed by the libraries, the lack of knowledge on questions of personal data protection, the complexity of the modern automated systems adopted by libraries, the vertical increase in the quantities of information stored by these systems, as well as the increasing interest of actors, mostly alien to the library environment, in researching and exploiting library archives, constitute potential threats against the privacy and individual rights of the receivers of library services. In the context of the current research, the aim is to highlight the problems in protecting privacy against personal data collection and processing in the frame of libraries and information services. The research contains a general overview of the relevant regulating and self-regulating efforts on international and European level and explores the best ways of managing the conflicting rights and legal interests in the environment of the libraries, through the study of the methods and practices developed in order to respond to the problems of personal data protection in the environment of the internet and the information society. Given the fact that there have been no previous studies on the issue of personal data protection in the environment of Greek libraries, the present contribution includes the results of research conducted on a representative sample, attempting to record the views of librarians and information professionals on the questions of privacy and personal data protection. Finally, the risks from personal data processing in information services are analyzed and a draft professional code of ethics is proposed. This proposal takes into consideration the Greek legislation, the needs and particularities of libraries, as well as the most suitable existing information technologies for the protection of privacy.

Title Comparative review of the thesauri ISO standards and of the Topic Maps ISO standard and implementation in RDF syntax and/or ontology languages
Creator Tsoli, Theodora
Date 2005
Abstract The objective of the work is to demonstrate some of the multiple possibilities of encoding and representation that Topic Maps present (ISO 13250:2002 Topic Maps) via the modelling knowledge organisation systems such as thesauri. The objective is achieved via the description of models and the comparison of the syntactic model of Topic Maps standard and the guidelines regarding the construction of thesauri (ISO 2788 and ISO 5964). The work also includes the implementation of drawn conclusions in the encoding of a sample of a monolingual thesaurus with use of Topic Maps syntax defined in the XML Topic Maps specification (XTM 1.0). Finally, we present a sample export of the application in RDF syntax along with a synopsis of the discussion regarding the relation of Topic Maps and RDF and the potential of Topic Maps to cooperate with one of the most dynamic constituent element of the Semantic Web. Topic Maps can be used with positive results for the modelling of thesauri because they materialise an abstract subject metadata representational model incorporating into a single object (topic) the subjects, their characteristics and their relations with other subjects found in a thesaurus. Therefore, it enables a thesaurus to exploit all the available syntactic possibilities in order to acquire a notation that will represent all its semantic content with completeness.
