Bc. Jana Kvašová 2011 Digital libraries of commercial publishers Abstract (in English): The aim of the thesis is to analyze and compare the current state of selected digital libraries of the most significant commercial publishers of scientific literature (SpringerLink, Wiley Online Library, ScienceDirect). The first chapter describes digital libraries in general and points out some of the specifics of digital libraries owned by commercial publishers. Basic terms like "digital library", "digital source", "digital document" are also explained in this chapter. The core of the thesis is represented by three analyses of selected digital libraries; Wiley Online Library (http://onlinelibrary.wiley.com/), SpringerLink ( http://www.springerlink.com/) and SciVerse ScienceDirect (http://www.sciencedirect.com/). The following chapter describes the connecting of digital libraries using the CrossRef service. The final chapter compares the main features of digital libraries and presents trends and possible future of this field.

Seit vergangenem Jahr ist die Sächsische Landesbibliothek– Staats- und Universitätsbibliothek Dresden (SLUB) mit drei ihrer Spitzenstücke in der World Digital Library (WDL) vertreten (www.wdl.org). Neben der Bayerischen Staatsbibliothek München und der Staatsbibliothek zu Berlin – Preußischer Kulturbesitz, ist die SLUB Dresden damit die dritte Partnerinstitution aus Deutschland.

There are common pitfalls and neglected areas when using clustering approaches to solve educational problems. A clustering algorithm is often used without the choice being justified. Few comparisons between a selected algorithm and a competing algorithm are presented, and results are presented without validation. Lastly, few studies fully utilize data provided in an educational environment to evaluate their findings. In response to these problems, this thesis describes a rigorous study comparing two clustering algorithms in the context of an educational digital library service, called the Instructional Architect. First, a detailed description of the chosen clustering algorithm, namely, latent class analysis (LCA), is presented. Second, three kinds of preprocessed data are separately applied to both the selected algorithm and a competing algorithm, namely, K-means algorithm. Third, a series of comprehensive evaluations on four aspects of each clustering result, i.e., intra-cluster and inter-cluster distances, Davies-Bouldin index, users' demographic profile, and cluster evolution, are conducted to compare the clustering results of LCA and K-means algorithms. Evaluation results show that LCA outperforms K-means in producing consistent clustering results at different settings, finding compact clusters, and finding connections between users' teaching experience and their effectiveness in using the IA. The implication, contributions, and limitation of this research are discussed.

Bibliography: leaves 207-224 / Abstracts and keywords following the Appendices / This thesis evaluates Ethiopian higher learning institutes’ digital libraries (DLs) for their usability and usefulness. The outcome contributes knowledge by helping to propel development efforts; satisfy DL stakeholders; provide information and fill information gaps; serve as cross-reference for academicians and researchers in the discipline; make decisions and solve managerial issues in DLs of the developing world; and provide scientific interests and merits for the advancement of information systems. When undertaking usability and usefulness evaluation research in DLs, there is no agreed-upon established conceptual framework that guides researchers in the developing world. Therefore, the overall objective of this research is to propose a framework for DL evaluation that fits into the context of developing countries. As the study is concerned with users’ internal attributes, the interpretive research paradigm is applied. A qualitative research approach is employed and a case study research design is followed. Multiple data-collection techniques, namely semi-structured interviews (17 respondents), open-ended questionnaires (17 respondents) and observations (4 observations) are employed. The study encompasses four public university DLs in Ethiopia. The participants have a positive perception of all attributes of usability. Most of the attributes of usefulness are also perceived positively, except coverage. The major challenges encountered by participants are network accessibility, interruption and speed, and access restrictions imposed on some DL content. DL benefits include easy access to the DL content, enhanced teaching and research, lower cost and easy sharing of contents. The expectations of users are ensuring resource availability and sustainability, overcoming the absence of user feedback and federated search problems, and improving network infrastructure and speed. The interaction triptych framework (ITF), which is used in the current study, is a well-known framework that is commonly implemented by researchers. However, since it does not incorporate the contextual situation of developing countries, ITF has some limitations. Therefore, based on the output of this empirical research and considering the usability and usefulness themes of ITF and its relationships with other socio-technical and contextual themes, a contextual DL evaluation framework is proposed. The proposed framework emphasises the social, institutional and contextual aspects of DLs. The proposed framework has six DL components, namely: DL user; content and collection; system and technology; services and support; user interface; and context. The proposed framework is called a digital library components interaction evaluation framework. / Lo mqondo uhlaziya imitapo yolwazi yedijithali (i-DLs) yezikhungo zokufunda ephezulu zase-Ethiopia ngokusebenziseka kwazo nokuba wusizo. Umphumela unikela ngolwazi ngokusiza ukuhambisa imizamo yentuthuko; ukwanelisa ababambiqhaza be-DL; ukuhlinzeka ngolwazi nokugcwalisa izikhala zolwazi; ukusebenza okubhekiswe kukho kwezifundiswa nabaphenyi emkhakheni; yenza izinqumo futhi ixazulule izingqinamba zokuphatha kuma-DL wezwe elisathuthuka; futhi unikeze izintshisekelo zesayensi kanye nokufaneleka ekuthuthukisweni kwezinhlelo zolwazi. Lapho wenza ucwaningo lokusebenziseka neliwusizo okuhlaziya kuma-DL, akukho luhlaka lomqondo okuvunyelwene ngalo oluhola abacwaningi ezweni elisathuthuka. Ngakho-ke, inhloso ephelele yalolu cwaningo ukuphakamisa uhlaka lokuhlaziya kwe-DL oluhambisana nomongo wamazwe asathuthuka. Njengoba ucwaningo luphathelene nezimpawu zangaphakathi zabasebenzisi, inqubo yocwaningo ehumushekayo iyasetshenziswa. Indlela yokucwaninga esezingeni elifanele iyasetshenziswa bese kulandelwa ukwakheka kocwaningo lwesifundo. Kusetshenziswa amasu amaningi wokuqoqa imininingwane, njengezingxoxo ezihlelwe kahle (abaphenduli abayi-17), imibuzo evulekile (abaphenduli abayi-17) kanye nokubhekwayo (okubhekwayo oku-4). Lolu cwaningo luhlanganisa ama-DL amane wemfundo ephakeme yomphakathi wase-Ethiopia. Abahlanganyeli banombono omuhle wazo zonke izici zokusebenziseka. Iningi lezimpawu eziwusizo zibonwa kahle futhi, ngaphandle kokumbozwa. Izinselela ezinkulu ababambiqhaza abahlangabezana ngazo ukufinyeleleka kwenethiwekhi, ukuphazamiseka nejubane, nemikhawulo yokufinyelela ebekiwe kokunye okuqukethwe kwe-DL. Izinzuzo ze-DL zifaka ukufinyelela okulula kokuqukethwe kwe-DL, ukufundiswa okuthuthukisiwe nocwaningo, izindleko eziphansi nokwabelana okulula kokuqukethwe. Okulindelwe abasebenzisi ukuqinisekisa ukutholakala kwezinsiza nokusimama, ukunqoba ukungabi bikho kwempendulo yomsebenzisi nezinkinga zokusesha ezihlanganisiwe, nokwenza ngcono ingqalasizinda yenethiwekhi nejubane. Uhlaka lokusebenzisana lwe-triptych (ITF), olusetshenziswa ocwaningweni lwamanje, uhlaka olwaziwa kakhulu olusetshenziswa ngokuvamile ngabaphenyi. Kodwa-ke, njengoba lungafaki isimo somongo samazwe asathuthuka, i-ITF inemikhawulo ethile. Ngakho-ke, ngokuya ngokukhishwa kwalolu cwaningo olunamandla kanye nokubheka ukusebenziseka nosizo lwezindikimba ze-ITF kanye nobudlelwano bayo nezinye izingqikithi zomphakathi nezobuchwepheshe nezingqikithi zomongo, kuhlongozwa uhlaka lokuhlaziya lomongo lwe-DL. Uhlaka oluhlongozwayo lugcizelela izici zenhlalo, zesikhungo nezingqikithi zomongo zama-DL. Uhlaka oluhlongozwayo lunezingxenye eziyisithupha ze-DL, okuyilezi: Umsebenzisi we-DL; okuqukethwe neqoqo; uhlelo nobuchwepheshe; izinsizakalo nokwesekwa; isikhombimsebenzisi somsebenzisi nomongo. Uhlaka oluhlongozwayo lubizwa ngohlaka lokuhlaziya kokusebenzisana kokuqukethwe komtapo wolwazi wedijithali. / Hierdie proefskrif evalueer Ethiopië se hoër leerinstellings se digitale biblioteke (DBe) ten opsigte van hulle bruikbaarheid en nuttigheid. Die uitkoms dra by tot kennis wat kan help om die ontwikkelingspogings aan te dryf; om belanghebbers van digitale biblioteke tevrede te hou; om inligting te verskaf en inligtingsgapings te vul; deur te dien as kruisverwysing vir akademici en navorsers in die vakgebied; om besluite te neem en bestuursaangeleenthede in digitale biblioteke van die ontwikkelende wêreld op te los; en om wetenskaplike belange en meriete vir die bevordering van inligtingstelsels te voorsien. Wanneer bruikbaarheids- en nuttigheidsevalueringsnavorsing in digitale biblioteke onderneem word, is daar geen ooreengekome, gevestigde raamwerk wat leiding aan navorsers in die ontwikkelende wêreld kan gee nie. Die algehele doelwit van hierdie navorsing was derhalwe om ’n raamwerk vir die evaluaering van digitale biblioteke voor te stel wat in die konteks van ontwikkelende lande pas. Omdat die studie gemoeid is met gebruikers se interne eienskappe, is die vertolkende paradigma gebruik. ’n Kwalitatiewe navorsingsbenadering is gebruik en ’n gevallestudie-navorsingsontwerp is gevolg. Veelvuldige data-insamelingstegnieke, naamlik semigestruktureerde onderhoude (17 respondente), oop vraelyste (17 respondente) en waarnemings (vier waarnemigs), is ingespan. Die studie sluit vier openbare universiteite se digitale biblioteke in Ethiopië in. Die deelnemers het ’n positiewe persepsie van al die eienskappe van bruikbaarheid. Die meeste van die eienskappe van nuttigheid word ook as positief waargeneem, met die uitsluiting van voorsiening. Die grootste uitdagings wat die deelnemers ervaar het, was netwerktoeganklikheid, -onderbrekings en -spoed en die toegangbeperkings wat sommige digitale biblioteke oplê. Voordele van digitale biblioteke sluit die volgende in: toegang tot digitalebiblioteekinhoud; beter onderrig en navorsing; laer koste; en die maklike deel van inhoud met ander. Die verwagtings van gebruikers verseker hulpbronbeskikbaarheid en -volhoubaarheid, en om die afwesigheid van gebruikersterugvoer en gefedereerde soekprobleme en die verbetering van netwerkinfrastruktuur en -spoed te oorkom. Die interaksietriptiekraamwerk (ITF) wat in hierdie studie gebruik is, is ’n bekende raamwerk wat algemeen deur navorsers geïmplementeer word. Omdat dit egter nie die kontekstuele situasie van ontwikkelende lande inkorporeer nie, het ITF sekere beperkings. Gebaseer op die uitset van hierdie empiriese navorsing en met die inagneming van die bruikbaarheids- en nuttigheidstemas van ITF en sy verhouding met ander sosio-tegniese en kontekstuele temas, word ’n kontekstuele digitalebiblioteekraamwerk derhalwe voorgestel. Die voorgestelde raamwerk beklemtoon die sosiale, institusionele en kontekstuele aspekte van digitale biblioteke. Die voorgestelde raamwerk het ses digitalebiblioteekkomponente, naamlik: digitalebiblioteekgebruiker; inhoud en insameling; stelsel en tegnologie; dienste en ondersteuning; gebruikerkoppelvlak; en konteks. Die voorgestelde raamwerk word ’n interaksie-evalueringsraamwerk vir digitalebiblioteekkomponente genoem. / School of Computing / D. Phil. (Information Systems)

This thesis aims to understand transcription as a critical transmission practice in the digital medium in order to add to the research surrounding digital library initiatives that make these research materials available and accessible. The project to transcribe the records of Lapland priest J. A. Nensén at Umeå University aims to publish the transcriptions in the cultural heritage database Alvin by Uppsala University Library. Looking at these two Swedish projects can better illustrate the issues surrounding digital tool application and integration. This thesis first explores the transcription practices of a group of scholars transcribing J. A. Nensén’s records. By understanding their model, a better picture of transcription as a scholarly practice can be achieved that can be useful when selecting a digital transcription tool. The study then identified appropriate transcription tools and reviewed the ones most applicable for the project based on the group’s paradigm. It was discovered that the main disparity in transcription practice is the balance between producing a diplomatic transcription and one that is readable. The primary consideration in transcription tool selection was found to be the goals of the project; in this case, those of the transcribers. This determined the tools to be reviewed. These were: FromThePage, Scripto, T-Pen, and Wikisource. All the tools are suitable to the editors, but they still present some obstacles in regards to diplomatic transcription.

Imagens de documentos são documentos digitalizados com conteúdo textual. Estes documentos são compostos de caracteres e diagramação, apresentando características comuns entre si, como a presença de bordas e limites no formato de cada caractere. A relação entre as características das imagens de documentos e os impactos do processo de compressão com respeito à fidelidade visual são analisadas nesse trabalho. Métricas objetivas são empregadas na análise das características das imagens de documentos, como a medida da atividade da imagem (IAM) no domínio espacial dos pixels, e a verificação da medida de atividade espectral (SAM) no domínio espectral. Os desempenhos das técnicas de compressão de imagens baseada na transformada discreta de cosseno (DCT) e na transformada discreta de Wavelet (DWT) são avaliados sobre as imagens de documentos ao aplicar diferentes níveis de compressão sobre as mesmas, para cada técnica. Os experimentos são realizados sobre imagens digitais de documentos impressos e manuscritos de livros e periódicos, explorando texto escritos entre os séculos 16 ao século 19. Este material foi coletado na biblioteca Brasiliana Digital (www.brasiliana.usp.br), no Brasil. Resultados experimentais apontam que as medidas de atividade nos domínios espacial e espectral influenciam diretamente a fidelidade visual das imagens comprimidas para ambas as técnicas baseadas em DCT e DWT. Para uma taxa de compressão fixa de uma imagem comprimida em ambas técnicas, a presença de valores superiores de IAM e níveis menores de SAM na imagem de referência resultam em menor fidelidade visual, após a compressão. / Document images are digitized documents with textual content. These documents are composed of characters and their layout, with common characteristics among them, such as the presence of borders and boundaries in the shape of each character. The relationship between the characteristics of document images and the impact of the compression process with respect to visual fidelity are analyzed herein. Objective metrics are employed to analyze the characteristics of document images, such as the Image Activity Measure (IAM) in the spatial domain, and assessment of Spectral Activity Measure (SAM) in the spectral domain. The performance of image compression techniques based on Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) are evaluated from document images by applying different compression levels for each technique to these images. The experiments are performed on digital images of printed documents and manuscripts of books and magazines, exploring texts written from the 16th to the 19th century. This material was collected in the Brasiliana Digital Library in Brazil. Experimental results show that the activity measures in spatial and spectral domains directly influence the visual fidelity of compressed images for both the techniques based on DCT and DWT. For a fixed compression ratio for both techniques on a compressed image, higher values of IAM and low levels of SAM in the reference image result in less visual fidelity after compression.

This investigation can be characterized as a dynamic approach to Systemic and Integral Action Research (PAIS: Pesquisa-Ação Integral e Sistêmica). This forms part of Anthropological Pedagogy that has as its object an educational process that involves the principles of Anthropology and Pedagogy. Consequently, we have a methodological proposal of research action of the educational act in the classroom assessed by the library. The interpretation of this data considers the signs, indications, and evidence of the CEPAE-UFG Elementary School, Goiânia, Goiás, Brazil (Centro de Ensino e Pesquisa Aplicada à Educação - Universidade Federal de Goiás-Brasil). It also takes into account the schools physical structure: classrooms, school library, computer rooms. The interpretation of the data of this experience was based on categorical analysis relative to the following concepts: reader, information literacy, and information literacy applied to literature. The latter were the reference and object of researchers investigation. Conceptual approaches relative to information literacy and information literacy applied to literature, reader, and the reading of literature were thus constructed. So as to define the concepts of reader and reading, the theoretical works of Wolfgang Iser and Antonio Cândido were pursued. On literacy, literary and informational, Magda Soares, Jack Goody & Ian Watt, John R. Bormuth, Graça Paulino, Egon de Oliveira Rangel, Bernadete Campello, Kelly Cristine G.D. Gasque and Carol C. Kuhlthau were relied on. The readers experience, successes and failures, through dialogue, amidst a theoretical approach and results that have been evidenced along a journey with the students of the sixth grade classes of CEPAE-UFG Elementary School has been discerned. This allowed us to identify the practice of literary and informational reading in the classroom and library environment. / Esta pesquisa tem como foco investigar a relação do leitor escolar com a biblioteca digital para acessar e manejar informações relevantes relativas à sua formação literária. Trata-se de um estudo caracterizado como Pesquisa-Ação Integral e Sistêmica (PAIS), numa abordagem dinâmica. A Antropopedagogia tem como objeto um processo educativo que envolve os princípios da Antropologia e os da Pedagogia. Daí, a proposta metodológica da pesquisa-ação do ato educativo em sala de aula junto à biblioteca, cuja interpretação dos dados leva em conta indícios, sinais e pistas na escola Centro de Ensino e Pesquisa Aplicada à Educação, da Universidade Federal de Goiás-Brasil e seus espaços: sala de aula, biblioteca escolar e sala de informática. O processamento e a análise dos dados da experiência foram realizados a partir de categorias de análise fundamentadas na concepção relativa aos conceitos: leitor, leitura literária, letramento informacional e literário, tendo como referência os objetivos desta investigação. Foram estabelecidas aproximações conceituais relativas a letramento informacional e literário, leitor e leitura literária. Para delimitar os conceitos leitor e leitura, recorremos aos teóricos Wolfgang Iser e Antônio Candido; sobre letramento, letramento literário e informacional contamos com Magda Soares, Jack Goody e Ian Watt, John R. Bormuth, Graça Paulino e Egon de Oliveira Rangel, Bernadete Campello, Kelley Cristine G. D. Gasque e Carol C. Kuhlthau. Identificamos a experiência do leitor, seus caminhos e seus descaminhos, mediante diálogo entre a abordagem teórica e os resultados evidenciados ao longo da experiência compartilhada com duas turmas do 6º ano do ensino fundamental, do CEPAE-UFG, o que permitiu identificar a prática de leitura literária e informacional no âmbito da sala de aula e da biblioteca.
