Mapping the Bid Behavior of Conference Referees

The peer-review process, in its present form, has been repeatedly criticized. Of the many critiques ranging from publication delays to referee bias, this paper will focus specifically on the issue of how submitted manuscripts are distributed to qualified referees. Unqualified referees, without the proper knowledge of a manuscript's domain, may reject a perfectly valid study or potentially more damaging, unknowingly accept a faulty or fraudulent result. In this paper, referee competence is analyzed with respect to referee bid data collected from the 2005 Joint Conference on Digital Libraries (JCDL). The analysis of the referee bid behavior provides a validation of the intuition that referees are bidding on conference submissions with regards to the subject domain of the submission. Unfortunately, this relationship is not strong and therefore suggests that there exists other factors beyond subject domain that may be influencing referees to bid for particular submissions

Finding and Using Moving Images in Context

Using selected moving images from Northeast Historic Film, this project will take a team approach to achieve open access with a metadata system incorporating emerging standards for discovery. We will emphasize contextualization, building tools to provide access to articles, scene-by-scene notes, both item-level and collection-level descriptive records, and we will integrate this information with new curriculum materials through easy-to-use interfaces. Partners are Primary Source and China Source, Maine Historical Society's Maine Memory Network, MIC, and the University of Maine's Windows on Maine. Three China scholars associated with Primary Source are committed to the project. We will digitize and put online unique footage of China,1928-1936, with rights to reuse, and we will ensure that researchers can easily find, identify, understand, and use the moving images. Teachers will participate in evaluation, informing decisions regarding follow-up initiatives

Metadata Quality for Digital Libraries

The quality of metadata in a digital library is an important factor in ensuring access for end-users. Several studies have tried to define quality frameworks and assess metadata but there is little user feedback about these in the literature. As collections grow in size maintaining quality through manual methods becomes increasingly difficult for repository managers. This research presents the design and implementation of a web-based metadata analysis tool for digital repositories. The tool is built as an extension to the Greenstone3 digital library software. We present examples of the tool in use on real-world data and provide feedback from repository managers. The evidence from our studies shows that automated quality analysis tools are useful and valued service for digital libraries

Optimizing E-Management Using Web Data Mining

Today, one of the biggest challenges that E-management systems face is the explosive growth of operating data and to use this data to enhance services. Web usage mining has emerged as an important technique to provide useful management information from user's Web data. One of the areas where such information is needed is the Web-based academic digital libraries. A digital library (D-library) is an information resource system to store resources in digital format and provide access to users through the network. Academic libraries offer a huge amount of information resources, these information resources overwhelm students and makes it difficult for them to access to relevant information. Proposed solutions to alleviate this issue emphasize the need to build Web recommender systems that make it possible to offer each student with a list of resources that they would be interested in. Collaborative filtering is the most successful technique used to offer recommendations to users. Collaborative filtering provides recommendations according to the user relevance feedback that tells the system their preferences. Most recent work on D-library recommender systems uses explicit feedback. Explicit feedback requires students to rate resources which make the recommendation process not realistic because few students are willing to provide their interests explicitly. Thus, collaborative filtering suffers from “data sparsity” problem. In response to this problem, the study proposed a Web usage mining framework to alleviate the sparsity problem. The framework incorporates clustering mining technique and usage data in the recommendation process. Students perform different actions on D-library, in this study five different actions are identified, including printing, downloading, bookmarking, reading, and viewing the abstract. These actions provide the system with large quantities of implicit feedback data. The proposed framework also utilizes clustering data mining approach to reduce the sparsity problem. Furthermore, generating recommendations based on clusters produce better results because students belonging to the same cluster usually have similar interests. The proposed framework is divided into two main components: off-line and online components. The off-line component is comprised of two stages: data pre-processing and the derivation of student clusters. The online component is comprised of two stages: building student's profile and generating recommendations. The second stage consists of three steps, in the first step the target student profile is classified to the closest cluster profile using the cosine similarity measure. In the second phase, the Pearson correlation coefficient method is used to select the most similar students to the target student from the chosen cluster to serve as a source of prediction. Finally, a top-list of resources is presented. Using the Book-Crossing dataset the effectiveness of the proposed framework was evaluated based on sparsity level, and Mean Absolute Error (MAE) regarding accuracy. The proposed framework reduced the sparsity level between (0.07% and 26.71%) in the sub-matrices, whereas the sparsity level is between 99.79% and 78.81% using the proposed framework, and 99.86% (for the original matrix) before applying the proposed framework. The experimental results indicated that by using the proposed framework the performance is as much as 13.12% better than clustering-only explicit feedback data, and 21.14% better than the standard K Nearest Neighbours method. The overall results show that the proposed framework can alleviate the Sparsity problem resulting in improving the accuracy of the recommendations

Biblioteca e centro de documentação da Comissão Nacional da Unesco, passado, presente e futuro

Trabalho de projecto de mestrado, Ciências da Documentação e da Informação (Biblioteconomia), Universidade de Lisboa, Faculdade de Letras, 2014A UNESCO e Comissão Nacional da UNESCO (CNU) Portuguesa, instituída no nosso país em 1981 no Ministério dos Negócios Estrangeiros através do Decreto-Lei nº218/79, têm como objectivos principais: contribuir para a paz de uma forma activa; para o desenvolvimento humano e segurança no mundo; para a promoção do pluralismo, para o reconhecimento e promoção da diversidade cultural e contribuir para a autonomia na sociedade do conhecimento. A Biblioteca e Centro de Documentação (BCD) da CNU tinha como papel principal apoiar e suportar as diferentes valências da organização, no âmbito da Educação, da Ciência, da Cultura e da Comunicação. Difundindo e promovendo as suas actividades, os seus projectos e programas, através da selecção, do processamento, da organização, da divulgação e promoção dos diversos recursos de informação e documentação, independentemente da sua tipologia, suporte físico e localização. Face às alterações sociais e económicas que Portugal e o mundo têm sido sujeitos, vivendo-se numa época de cortes e restrições orçamentais em todas as áreas da sociedade, tanto a CNU como a sua BCD ressentiram-se com as mesmas, sofrendo alterações ao nível da sua estrutura e da sua localização física. A realização de um projecto de dissertação de mestrado teve como ponto de partida o trabalho efectuado na Biblioteca e Centro da CNU durante mais de um ano, e a constatação das particularidades desta biblioteca especializada. No entanto, as rápidas transformações levaram a que o rumo do trabalho tivesse de ser restruturado. Procurou-se reconstruir parte da história da CNU e da sua BCD, salientando a sua capacidade de adaptação dentro do espírito da UNESCO de promoção e diálogo entre os povos para uma cultura da paz e de respeito pelos direitos humanos. Tendo presente o papel dos profissionais de informação e do conhecimento como agentes promotores de mudança, sendo a educação e o conhecimento forças motrizes para um desenvolvimento sustentável assente na promoção da diversidade contribuindo para a concretização da paz, do respeito e da promoção do ser humano. Pretendeu-se reflectir sob as potencialidades e desafios que se colocam à CNU e à sua BCDABSTRACT The Portuguese National Commission for UNESCO (NCU), which is associated with the Ministry of Foreign Affairs, was established in our country in 1981 under the Decree-Law 218/79. The main objectives of UNESCO as well as the Portuguese National Commission for UNESCO are: to contribute to peace in an active way, to humanitarian development, to world security, to pluralism promotion as a step to the recognition of cultural diversity and to contribute to the culture of spreading knowledge. The Documentation Centre and Library (DCL) of NCU supported the organization in different areas such as Education, Science, Culture and Communication by coordinating efforts in spreading and promoting its activities, projects and programmes through the selection, processing, and promotion of various information documentation resources, regardless their typology, location, or physical support. Due to social and economic changes, Portugal and the world have been facing budget cuts in every social area. This way, both NCU and DCL were forced to make some changes in what their structure and location are concerned. This paper is the result of a research work made in the Library and NCU centre for more than a year. During this time, this place showed all its particularities. However, the paper suffered some transformations. Part of the history of NCU and its DCL was rebuilt, emphasising UNESCO values of promoting dialogue between people to reach peace and re mean for the construction of thought and the blossoming of peace, respect and the human being, and theref enabling factor for sustainable development, this paper shows a reflection of the potentials and challenges that NCU and DCL face

A new framework for building digital library collections

This paper introduces a new framework for building digital library collections and contrasts it with existing systems. It describes a significant new step in the development of a widely-used open-source digital library system, Greenstone, which has evolved over many years. It is supported by a fresh implementation, which forced us to rethink the entire design rather than making incremental improvements. The redesign capitalizes on the best ideas from the existing system, which have been refined and developed to open new avenues through which digital librarians can tailor their collections. We demonstrate its flexibility by showing how digital library collections can be extended and altered to satisfy new requirements
