Esta informação é muito importante para que um pesquisador selecione veículos de renome para publicar suas pesquisas, ou mesmo, instituições podem promover seus pesquisadores baseando-se na qualidade dos veículos onde publicam. Esta informação sobre os veículos pode também ser valiosa para um governo destinar recursos 'as instituições ou uma empresa avaliar a qualidade de um candidato a um emprego. Existem várias métricas distintas para realizar ranking de veículos, mas o ponto comum entre a maioria é o uso de citações. Portanto, por mais que um veículo seja bastante prestigiado pelos pesquisadores, se ele não for indexado em uma base sua qualidade não será considerada. Este trabalho propõe um método para ranking de veículos de publicação obtendo as informações não de uma base de citações existente, mas de uma outra fonte de dados: a Web. As páginas dos professores de universidades são visitadas e delas são extraídas as suas publicações. De cada publicação é extraído o veículo e dessa forma, baseado nos veículos que um pesquisador quis exibir em sua página, os mesmos são ordenados. Este método irá contemplar veículos de publicação não existentes nas atuais bases de dados criando um novo ranking de publicações. Vários problemas computacionais interessantes são abordados neste trabalho: busca de informação na internet, segmentação textual, extração de componentes em uma referência bibliográfica e agrupamento / Abstract: Several current ranking methods compare different publication venues in relation to quality or impact. This information is very important for a researcher to choose renowned venues to publish his research. Institutes could promote their researchers based on the quality of places they have published. This information about the venues can also be valuable for a government to allocate resources to universities, or for companies to evaluate the quality of a candidate for a job. There are other distinct measures to perform a ranking of venues, but the idea in common among most of them is the use of citations. Therefore, despite the fact a venue is very prestigious for its researchers, if it is not indexed in a citation database, it will not be considered, since its "quality" cannot be measured. This work proposes to construct a ranking of publication venues obtaining the information not from a database, but from another data source: the Web. The university professor's webpages are visited to extract the publications. The venue is extracted from each publication, and thus, based on venues which a researcher wanted to show in his webpage, they are ranked. This method will include publication venues that do not exist in current databases, creating a new ranking of publications. Many interesting computational problems are discussed in this work: information search on the internet, text segmentation, extraction of components in a bibliographic citation, and clustering / Mestrado / Metodologia e Tecnicas da Computação / Mestre em Ciência da Computação

O ensino universitário tem buscado cada vez mais formar profissionais com espírito crítico e reflexivo, aproximando-os da realidade desde seu estágio como estudante. A biblioteca universitária tem sido vista freqüentemente como ambiente de apoio às atividades de ensino, pesquisa e extensão na academia. Entretanto, é também sua função, contribuir para a inserção do estudante no universo da pesquisa acadêmica, desenvolvendo atividades de mediação junto ao usuário nos processos de busca da informação para que ele tenha condições de transformá-la em conhecimento. Considera-se a importância da Biblioteconomia e da Ciência da Informação dialogarem com outras áreas do conhecimento tais como a Educação, a Metodologia Científica e a Psicologia. Abordam-se os conceitos de informação e conhecimento, biblioteca universitária, estudos e educação de usuários. Objetiva-se discutir o papel do bibliotecário na educação de usuários, entendendo a biblioteca como espaço de aquisição do conhecimento. O estudo é baseado no processo construtivista de busca de informação (ISP) de Carol Kuhlthau. A pesquisa é de caráter exploratório com abordagem qualitativa através de entrevistas com alunos de graduação e pós-graduação de faculdades das três áreas do conhecimento, Humanas, Biológicas e Exatas da Universidade de São Paulo. Ao final da análise conclui-se que há necessidade e espaço para que e a biblioteca universitária possa tornar-se ambiente propício a colaborar na aprendizagem do estudante universitário. / The learning process at the university has been increasingly trying to develop reflexive and critical professionals, offering them a close contact with the reality since their intern period as students. The academic library has been seen frequently as an environment to support learning, research and additional studies activities at the academia. Nevertheless, it also has the role to contribute to the student immersion on the academic research, developing activities as a medium for its users to search for information so that they could transform it in knowledge. It is taken into consideration the importance of Librarianship and Information Science to dialogue with other areas as Education, Scientific Methodology and Psychology. This paper deals with the concepts of information and knowledge, academic library, users studies and learning. Its goal is to discuss the role of the librarian in relation to its users education, understanding the library as a place to acquire knowledge. The study is based on the constructive Information Search Process (ISP) from Carol Kuhlthau. The research has an exploratory character with qualitative approach through interviews with students from graduation and post graduation from three fields: Humanities, Biological and Exact Sciences from Universidade de São Paulo (Sao Paulo University). By the end of the analysis, it is concluded that there is a need and space for the university library to become an environment proper to collaborate on the knowledge of the university student.

Tendo em vista a crescente degradação desses ecossistemas, aliado ao pouco conhecimento sobre a sua biodiversidade em regiões tropicais, esta tese tem como objetivo geral ampliar o conhecimento sobre nascentes de regiões tropicais e prover um estudo sobre a diversidade e aspectos ecológicos de oligoquetas aquáticos nesse ecossistema. A fim de confirmar a carência de estudos em nascentes, especificamente sobre a fauna de oligoquetas, foi feito um levantamento bibliográfico sobre os estudos realizados em 30 anos (1985-2015) nos mais diversos ambientes aquáticos continentais em todo o mundo. A pesquisa mostrou que nascentes estão entre os ecossistemas menos estudados, juntamente com corpos d’água de cavernas e pântanos. Também realizamos coletas da fauna, medimos variáveis físicas e químicas e aplicamos um protocolo de avaliação rápida (PAR) em nascentes localizadas em diferentes municípios de Minas Gerais, tanto em Unidades de Conservação (UCs) quanto em áreas públicas e particulares. Os resultados mostraram que a composição de espécies de oligoquetas de nascentes que emergem de forma difusa formando uma área alagada (helocreno), é diferente daquela de nascentes que formam riachos (reocreno) e poças (limnocreno), provavelmente devido à sua maior heterogeneidade. Também verificamos que a diversidade beta foi alta nas três tipologias, indicando que os esforços para a conservação desses ecossistemas devem incluir um grande número de nascentes de todas as tipologias. Os resultados desse estudo também enfatizam, após a aplicação do PAR, que, apesar da maioria das nascentes serem classificadas como ótimas, nascentes localizadas em áreas urbanas foram classificadas como razoável ou ruim, mesmo estando algumas delas em UCs. Isso mostra a importância das UCs na preservação das nascentes, assim como sua vulnerabilidade quando inseridas em ambientes urbanos. Concluímos que este estudo sobre as nascentes contribui não apenas para o conhecimento do tema, mas também para a gestão ambiental, pois direciona para os habitats e locais que mais carecem de estudo, mostra a importância de se preservar diferentes tipos de nascentes para a manutenção da diversidade e aponta para a necessidade de maior fiscalização e cumprimento dos dispositivos legais, a fim de evitar maiores alterações nas condições naturais desses ambientes. / Springs are important landscape elements due to its economic, social and ecological importance. In view of the increasing degradation of these ecosystems, added to low knowledge about their biodiversity in tropical regions, the main goal of this study is to increase the knowledge about springs in tropical regions and to provide information on the diversity and ecological aspects of aquatic oligochaetes in this ecosystem. To confirm the lack of studies in springs, specifically considering freshwater oligochaetes, a bibliographic survey has was made basead on the studies carried in a period of 30 years (1985-2015) in various continental aquatic environments around the world. The survey showed that spring are one of the least studied ecosystems, together with cave water bodies and swamps. For this study, fauna was collected, physical and chemical variables were measured, and a rapid assessment protocol (RAP) were applied at spring located in different cities of Minas Gerais State, either in Conservation Units or in public and private areas. The results showed differences among the oligochaetes species composition found in spring that rises diffusely forming a flooded area (helocrene), in comparasion to spring that forms streams (rheocrene) and that ones that forms a pond (limnocrene). Probably, it is due to the high heterogeneity of this kind of spring. We also verified that beta diversity was high at the three types of springs, suggesting that efforts to conserve these ecosystems should include many spring systems of all types. After applying RAP, this study emphasized that, besides the major numbers of spring, water have been classified as optimum also the springs located in urban areas were classified as moderate or poor, even when some of them were located in Conservation Units. This result highlights importance of Conservation Units on spring preservation, and also the vulnerability of these systems when inserted in urban environments. This study contributes not only for academic knowledge, but also for environmental management, once it points out the habitats and places that need more studies, showing the importance of preserving different types of spring systems for the maintenance of diversity. It also indicate the requirements for major inspections and the legal enforcement provisions needed, in order to avoid further transformations in the natural conditions of these systems.

The purpose of this study was to compare four different methods of bibliographic instruction in order to determine which method would have the most effect on student learning.

La ansiedad bibliotecaria (AB) es el estado de incertidumbre que experimentan algunos usuarios cuando acuden a la biblioteca, cuyo estudio comenzó en los años 80, pero que carece de un análisis métrico actualizado. El objetivo de este estudio fue hacer un análisis bibliométrico y cienciométrico de los artículos sobre AB indizados en la base de datos Scopus entre 1989 y 2018. Se analizaron 118 publicaciones según indicadores de producción, colaboración, impacto y mapas bibliométricos. Se encontró que las publicaciones sobre AB han aumentado progresivamente, que la colaboración de autores fue baja, que una revista influyente en el área fue Library Review, y que los autores con más impacto fueron Onwuegbuzie y Jiao. Asimismo, destacaron palabras clave sobre la formación del usuario y cuatro frentes de investigación: instrumentos de medición, resultados, marcos teóricos y tipos de unidades de análisis. Dichos resultados sugieren que la AB es un tema fructífero de investigación. / Library anxiety (LA) is the state of uncertainty experienced by some users when they come to the library, the study of which began in the 1980s but lacks updated metric analysis. The objective of this study was to make a bibliometric and scientometric analysis of the articles on LA indexed in the Scopus database between 1989 and 2018. 118 publications were analyzed according to indicators of production, collaboration, impact and bibliometric maps. It was found that publications on LA have progressively increased, that the collaboration of authors was low, that an influential journal in the area was Library Review, and that the authors with the greater impact were Onwuegbuzie and Jiao. Also, keywords on user training and four research fronts were highlighted: measurement instruments, results, theoretical frameworks and types of analysis units. These results suggest that LA is a fruitful research topic. / Revisón por pares

A recommender system is a subclass of information filtering system that seeks to predict the "rating" or "preference" a user would give to an item. These systems are present in a wide variety of applications and websites today. We can be aware of these recommendations when we are buying and articles similar to those we are looking for are suggested to us. However, they act in many other activities, such as in applications about restaurants and vacation trips. They also filter information from multimedia collections, such as Netflix or Amazon Prime. And furthermore, they are also present in browsers and they filter papers and books from repositories. They are subject to continuous research and improvement and the study of how these systems are being examined and evolve today is important because they literally filter the available information for us. This bibliometric study analyses the present-day research front on recommender systems. The chosen data source is the Web of Science bibliographic database and the study is performed following quantitative methods, using bibliometric techniques together with a qualitative assessment and interpretation of the most relevant research articles.

Thesis (MSc)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: We present a system that uses statistical machine learning to identify and extract bibliography information from scientific literature. Techniques for finding and gathering useful information from the ever growing volume of knowledge on the World Wide Web (WWW), are investigated. We use hidden Markov models both for recognition of bibliography styles and extraction of bibliographic information with an accuracy of up to 97%. The accuracy with which we are able to extract this information allows us to present a case study in which we apply methods of citation analysis to information extracted from three areas of machine learning. We use this information to identify core sets of papers that have made significant contributions to the fields of hidden Markov models, neural networks and recurrent neural networks. / AFRIKAANSE OPSOMMING: Ons bied 'n sisteem aan wat gebruik maak van statistiese masjiene wat leer om bibliografiese inligting uit wetenskaplikke literatuur te identifiseer en ontgin. Tegnieke wat aangewend word vir die verkenning en insameling van nuttige inligting vanaf die snel groeiende kennisbron van die WWW, word ondersoek. Ons gebruik verskuilde Markov modelle vir die herkenning van verwysingsstyl en ontginning van verwysingsinligting met 'n akuraatheidspeil van to 97%. Hierdie hoë ontginningsakuraatheid stelons in staat om 'n toepassing van die tegniek op die veld van masjiene wat leer toe te pas. Ons rapporteer hoe ons die tegnieke gebruik het om literatuur wat beduidende bydraes in die velde van verskuilde Markov modelle, neurale netwerke en terugkerende neurale netwerke, te identifiseer.

Research shows children in an online environment often search by browsing, which relies heavily on recognition and content knowledge, so catalog systems for children must use effective symbols or pictorial representations, which correspond with children's own cognitive schema and level of recognition knowledge. This study was designed to look at the success of young children (ages 5 to 8) in searching 3 online public library catalogs designed for them, and it focused specifically on the pictorial representations and text descriptors used in the systems' browsing hierarchy. The research sought answer whether young children (ages 5 to 8) are really poor searchers because of cognitive development and lack of technology skills or if system design is the major reason for poor search results; i.e., Do current children's online catalog designs function in a manner that is compatible with information seeking by children? Although these results can not be generalized, this study indicates that there was a disconnect between the cognitive abilities of young users and catalog design. The study looked at search success on the 3 catalogs in relation to the catalog characteristics and individual user characteristics and makes 3 significant contributions to the field of library and information science. The first contribution is the modification of an existing model posed by Cooper and O'Connor and modified by Abbas (2002). The second significant contribution is the proposal of a new model, Creel's second best choice (SBC) model, that addresses the cognitive gap and design flaws that impact the choices participants made. The third significant contribution is that this study addresses and fills a gap in the literature.

Objetivos. Reflexos das transformações sociais promovidas pela Sociedade do Conhecimento são percebidos no contexto da gestão em saúde no Brasil. Apresentam-se referencial teórico sobre essas mudanças, gestão do SUS, sistemas de informação em saúde, produção científica e uso da informação na gestão. Foi analisada a produção científica brasileira em saúde pública como fonte de apoio à tomada de decisão em saúde. Metodologia. Foram feitos estudo exploratório qualitativo e análise documental em três áreas: bases de dados bibliográficas disponíveis na Biblioteca Virtual em Saúde, agendas estaduais de saúde e sites das Secretarias Estaduais de Saúde. Resultados. Os principais resultados foram: as bases de dados LILACS e MEDLINE foram as fontes de apoio mais abrangentes para localizar produção brasileira publicada no país e no exterior, respectivamente; a produção científica brasileira destaca-se nessa área, correspondendo a 39 por cento dos registros da LILACS-SP; as principais instituições produtoras são universidades e organismos governamentais; a produção de saúde pública encontra-se distribuída em revistas de outras áreas da saúde; a internet, já utilizada pelo ministério e pelas secretarias de saúde, seria favorável para disseminação de conhecimento científico para a gestão em saúde. Conclusões e recomendações. A informação científica e técnica disponível poderia apoiar os processos de tomada de decisão, mas o caminho entre sua produção e uso não é linear e precisa ser estimulado. São apresentadas sugestões para promover integração e articulação entre pesquisa científica e decisão política. / Objectives. Social changes introduced by Knowledge Society are perceptible in the health management context in Brazil. Literature on these social changes, on National Health System - SUS legislation, on health information systems, on the health scientific production and on its use for decision making was reviewed. Brazilian public health scientific literature as support to health decision making was analyzed. Methods. Qualitative exploratory methods and document analysis were used to study bibliographic databases available at the Virtual Health Library, health agendas and sites of the State Secretaries of Health. Results. The main results were: LILACS and MEDLINE databases were the most comprehensive sources for searching Brazilian public health literature; 39 per cent of LILACS-SP records corresponds to Brazilian public health literature; universities and government institutions are the main producers of public health scientific literature; public health journal articles are published also in journals from other health fields; Internet, which is already being used by Ministry and State Secretaries of Health for communication, could be a favorable environment for dissemination of scientific information for health decision making. Conclusions and recommendations. Available health scientific and technical information could support health decision making processes but the channels between its production and use are not linear and need to be strengthened. Recommendations to improve relationship and interaction between health research and policy were presented.
