Titulo: Building a Digital Library for the Brazilian Computer Science
Community: Challenges and Opportunities

Abstract: The Brazilian Digital Library of Computing – BDBComp was created in 2003 as an experimental platform for the I3DL (Inference, Interoperability and Integration in Digital Libraries) project, a CNPq/NSF joint research project involving the UFMG Database Laboratory and the Virginia Tech Digital Library Research Laboratory. In these five years, BDBComp has evolved from a simple metadata catalog with basic services, such as searching and browsing [Laender et al. 2004], to a major repository of the scientific production of the Brazilian Computer Science community. Currently, BDBComp includes more than 5,500 citation entries of articles published in more than 100 Brazilian venues (conferences and journals), of which 37% includes a link to its full-text version. In addition to its basic services, BDBComp also automatically links its author’s pages to other bibliographic indexing systems, such as DBLP, CiteSeer, and Google Scholar, as well as provides more sophisticated services that allow its users to self-archive their own articles [Veiga e Silva et al. 2005, 2007] and search the Web for the full-text of cataloged articles for which there is no link available or the available link is broken [Santos et al. 2007]. In this talk, we will address the major challenges we have faced to build and maintain BDBComp, and discuss some of the opportunities this endeavor has opened to our research group [Laender et al. 2008].

Short Bio


Alberto H. F. Laender holds a BS degree in Electrical Engineering and an MSc degree in Computer Science, both from the Federal University of Minas Gerais, Brazil, and a PhD degree in Computing from the University of East Anglia, UK. He joined the Computer Science Department at the Federal University of Minas Gerais in 1975, where he is currently a Full Professor and the head of the Database Research Group. In 1997, he was a Visiting Scientist at HP Labs in Palo Alto, California. He has served on the advisory committee of several Brazilian research funding agencies and is currently a member of ACM SIGMOD's Advisory Board and PhD Dissertation Award Committee. Prof. Laender has also served as a program committee co-chair, as well as a program committee member, for several national and international conferences on databases, digital libraries and Web-related topics. He is the author of more than 100 refereed journal and conference papers, and was one of the co-founders of Akwan Information Technologies, a Brazilian search technology company acquired by Google Inc. in 2005. Prof. Laender’s research interests include conceptual modeling and database design, web data management, web information systems, and digital libraries.

Titulo: Banco de Dados e as Mudancas Ambientais Globais
(slides)

Resumo: O Painel Intergovernamental de Mudanças Climáticas (IPCC) fornece amplas evidências de que o clima do planeta já está mudando em resposta a este aquecimento. O IPCC projeta um aumento entre 1,8° C e 4° C para a temperatura média global até o final do corrente século. Isto indica que Mudanças Ambientais Globais serão uma das áreas de pesquisa mais importantes no século XXI. No caso brasileiro, é preciso estudar de impactos das mudanças climáticas no Brasil, as alternativas para reduzir as emissões brasileiras de gases de efeito estufa, e as adaptações possíveis dos sistemas sociais, econômicos e naturais. Todos estes estudos envolvem enorme quantidade de dados espaço-temporais de diferentes fontes e formatos. Esta palestra irá analisar os problemas de modelagem, armazenamento, recuperação e gerenciamento de dados para estudos em mudanças ambientais globais. A ênfase será em problemas científicos em aberto para a comunidade de Ciência de Computação, motivados por questões técnicas associadas aos estudos em Mudanças Ambientais Globais.

Gilberto Câmara é diretor do INPE (Instituto Nacional de Pesquisas Espaciais), com doutorado em Computação. Produziu 6 livros e mais de 150 artigos nas áreas de Ciência da Geoinformação, Bancos de Dados Geográficos, e Modelagem Ambiental. Sua pesquisa é focada em modelagem computacional dos sistemas sociais e da interação sociedade-natureza, com o uso de sistemas de informação geográfica. Trabalha atualmente no desenvolvimento de métodos e de software para modelagem de mudanças de uso da terra, com ênfase na Amazônia.

Title: Complex Analysis Tasks for Multidimensional Data

Abstract: The abundance of multi-dimensional information has raised the development of complex analysis tools for such data, beyond simple range and nearest-neighbor search. Specifically, a series of more advanced query-driven data mining tasks have emerged including the top-k query, the reverse nearest neighbor query, and the skyline query.  Specialized methods for these queries, which consider the variety of attribute domains (i.e., numerical, categorical, spatial, etc.), have been developed. In addition, based on  the newly introduced dominance relationship between two multi-dimensional vectors, novel  queries have been introduced (e.g., the top-k dominating query). More importantly, due to the curse of dimensionality and the flexibility given to a user to choose query dimensions, the application of such queries to dimensional sub-spaces has become a relevant issue. In this talk, I will review the recent developments on query-driven multidimensional data analysis, including work done in our research group, and present challenges for future research.

Nikos Mamoulis received a diploma in Computer Engineering and Informatics in 1995 from the University of Patras, Greece, and a PhD in Computer Science in 2000 from the Hong Kong University of Science and Technology. Since 2001 he has been a faculty member of the Department of Computer Science, University of Hong Kong, currently an associate professor. In the past, he has worked as a post-doctoral researcher at the Centrum voor Wiskunde en Informatica (CWI), the Netherlands. His research interests include complex data management, data mining, advanced indexing and query processing, and privacy-preserving data publishing. He has published over 75 articles in reputable international conferences and journals andserved in the program committees of major database and data mining conferences. He has been involved on the organization of several international conferences and workshops and he serves on the editorial board of Geoinformatica.
