The basis for bibliomining: Frameworks for bringing together usage-based data mining and bibliometrics through data warehousing in digital library services. Information Processing and Management 42(3), 785-804. Over the past few years, data mining has moved from corporations to other organizations. This paper looks at the integration of data mining in digital library services. First, bibliomining, or the combination of bibliometrics and data mining techniques to understand library services, is defined and the concept explored. Second, the conceptual frameworks for bibliomining from the viewpoint of the library decision-maker and the library researcher are presented and compared. Finally, a research agenda to resolve many of the common bibliomining issues and to move the field forward in a mindful manner is developed. The result is not only a roadmap for understanding the integration of data mining in digital library services, but also a template for other cross-discipline data mining researchers to follow for systematic exploration in their own subject domains.

This article presents findings from approximately 150 users who created instructional projects using educational digital library resources. One hundred of these users were teachers participating in professional development workshops on the topic of digital libraries. Our iterative approach to tool and workshop development and implementation was based on a framework that characterizes several input, output, and process variables affecting dissemination of such technologies in educational contexts. Data sources involved a mix of qualitative and quantitative methods, including electronic surveys, interviews, participant observations, and server log file and artifact analyses. These multiple and complementary levels of analyses reveal that despite teachers reporting great value in learning resources and educational digital libraries, significant and lasting impact on teaching practice remains difficult to obtain.

Artificial Intelligence Lab, Department of MIS, University of Arizona / This research investigated the application of techniques successfully used in previous information retrieval research, to the more challenging area of medical informatics. It was performed on a biomedical document collection testbed, CANCERLIT, provided by the National Cancer Institute (NCI) , which contains information on all types of cancer therapy. The quality or usefulness of terms suggested by three different thesauri, one based on MeSH terms, one based solely on terms from the document collection, and one based on the Unified Medical Language System UMLS Metathesaurus, was explored with the ultimate goal of improving CANCERLIT information search and retrieval. Researchers affiliated with the University of Arizona Cancer Center evaluated lists of related terms suggested by different thesauri for 12 different directed searches in the CANCERLIT testbed. The preliminary results indicated that among the thesauri, there were no statistically significant differences in either term recall or precision. Surprisingly, there was almost no overlap of relevant terms suggested by the different thesauri for a given search. This suggests that recall could be significantly improved by using a combined thesaurus approach.

Abstract: The present paper discusses some the important issues involved in presenting text on screen. It is argued that reading is a complex cognitive and physical skill that requires careful analysis if technology is going to support rather than hinder the user. The need to consider texts individually in terms of how and why they are read as well as the type of information they contain is discussed. On the basis of a study of journal usage the implications of this approach for the presentation of electronic journals is described.

Digital Library for Earth Science Education, DLESE / Review of digital educational resources, such as course modules, simulations, and data analysis tools, can differ from review of scholarly articles, in the heterogeneity and complexity of the resources themselves. The Partnership Review Model, as demonstrated in two cases, appears to promote cooperative interactions between distributed resource reviewers, enabling reviewers to effectively divide up the task of reviewing complex resources with little explicit coordination. The shared structural outline of the resource made visible in the review environment enables participants to monitor other reviewersâ actions and to thus target their efforts accordingly. This reviewing approach may be effective in educational digital libraries that depend on community volunteers for most of their reviewing.

Η ψηφιοποίηση περιεχομένου είναι πλέον μια καλά καθορισμένη διαδικασία σε παγκόσμια κλίμακα και αποσκοπεί στη διατήρηση και προβολή της πολιτιστικής κληρονομιάς των λαών. Παρόλα αυτά, η διαχείριση του ψηφιοποιημένου περιεχομένου και των μεταδεδομένων που το συνοδεύουν δεν έχει ωριμάσει σε τέτοιο βαθμό ώστε να ισχύει ένα κοινά αποδεκτό πρότυπο. Το γεγονός αυτό, σε συνδυασμό με το ότι ο όγκος των δεδομένων αυξάνεται συνεχώς καθιστά επιτακτική την ανάγκη δημιουργίας συστημάτων οργάνωσης και διαχείρισης τους. Οι Ψηφιακές Βιβλιοθήκες είναι συστήματα λογισμικού, που αποθηκεύουν και οργανώνουν την πληροφορία ώστε να παρέχουν προηγμένες υπηρεσίες αναζήτησης και πλοήγησης στους χρήστες τους. Αποτελούν δε, ένα ιδιαίτερα αναπτυσσόμενο πεδίο έρευνας και ανάπτυξης που συνδυάζει επιστημονικά πεδία από διάφορους τομείς. Στην παρούσα διπλωματική εργασία μελετάμε συστήματα Ψηφιακών Βιβλιοθηκών ανοικτού κώδικα καθώς και τα πρότυπα που έχουν προταθεί για την διαλειτουργικότητα του περιεχομένου τους. Επιπλέον, σημειώνουμε τις αδυναμίες των σύγχρονων συστημάτων Ψηφιακών Βιβλιοθηκών όσον αφορά στην κάλυψη των αναγκών ενός Πολιτιστικού Οργανισμού και επιλέγοντας τα πλέον ενεργά και χρησιμοποιούμενα από τη διεθνή κοινότητα πρότυπα δημιουργούμε ένα σύστημα που διασυνδέει Ψηφιακές Βιβλιοθήκες με συστήματα Διαχείρισης Περιεχομένου. Τέλος, η διασύνδεση επιτυγχάνεται με χρήση της γλώσσας XML και εφαρμόζεται σε δύο αντιπροσωπευτικά συστήματα από την κάθε κατηγορία. / Digitization of content is a well known process worldwide that aims in preserving and promoting national cultural heritage. Nevertheless, the management of digital content and of accompanying metadata has not matured to a globally respected standard. This fact combined with the rapid growth of digital content increases the need for the existence of systems that organize and manage this data. Digital libraries are software systems that store and organize data in order to provide advanced search and browsing services to their users. They compose a rapid growing domain of research that combines multiple scientific fields. In the present dissertation we study open source Digital Library Systems and the standards proposed for the interoperability of their content. In addition, we notice their inabilities to cover certain needs of a cultural heritage organization and choose the most popular standards in use today in order to interconnect Digital Library with Content Management Systems.

For the past two years the Massachusetts Institute of Technology (MIT) Libraries and Hewlett-Packard Labs have been collaborating on the development of an open source system called DSpace™ that functions as a repository for the digital research and educational material produced by members of a research university or organization. Running such an institutionally-based, multidisciplinary repository is increasingly seen as a natural role for the libraries and archives of research and teaching organizations. As their constituents produce increasing amounts of original material in digital formats—much of which is never published by traditional means—the repository becomes vital to protect the significant assets of the institution and its faculty. The first part of this article describes the DSpace system including its functionality and design, and its approach to various problems in digital library and archives design. The second part discusses the implementation of DSpace at MIT, plans for federating the system, and issues of sustainability.

An increase in collaboration between organizations building digital libraries has strengthened the need for tailored project management systems. Current project management tools do not handle the unique challenges that digital libraries pose from a management perspective. They require significant time to apply, and only provide partial solutions. To address this issue, we have designed, implemented, and deployed a Web-based management solution which caters to the planning needs of the project team during the initial phases of digital library development. The main aim of the tool is to capture digital library development patterns and to make development easy for collaborators. The key aspects of the tool are: i) use of the 5S framework of digital libraries to describe the managerial information system as well as the digital library being managed itself, ii) design that is centered on keeping the user informed about digital library practices by integrating appropriate user affordances into the tool, and iii) providing generic project management features such as timeline-creation and task-scheduling in addition to digital library customizations. A formative evaluation of the tool was performed using CTRnet and a national digital library as case studies. / Master of Science

Digital libraries are an integration of complex computer and information systems that could benefit from a formal approach to design. There are various design aspects to consider in a digital library; a crucial aspect is security. Security often is a requirement in digital libraries that should be considered during the design process and not as an add-on feature. 5S provides a DL modeling framework, to define all the aspects of a digital library. It covers the different formats and types of digital objects stored, how they are grouped and organized, what sequence of operations occur in the digital library, how the objects will be represented, and who is part of the digital library community. However, the 5S descriptive language (5SL) previously did not cover the essential security requirements in a digital library. The goal of this research is to extend the 5S framework to describe the security requirements in digital library. An XML schema was developed to describe the necessary security requirements in a digital library, and some of the essential features of the digital library design. This work explains the key security requirements needed in a digital library from the 5S perspective and how the framework can be extended to include these requirements. The extended 5SL was applied to a case study on the Egyptian University Libraries Consortium. / Master of Science
