Resumo
The concept of culture has been attractive to producers of interactive systems who are willing to design useful and relevant solutions to users increasingly located in culturally diverse contexts. Despite a substantial body of research on culture and technology, interaction designers have not always been able to apply these research outputs to effectively define requirements for culturally diverse users. I frame this issue as one of understanding of the different paradigms underpinning the cultural models being applied to interface development and research. Drawing on different social science theories, I will discuss top-down and bottom-up perspectives in the study of users’ cultural differences and discuss the extent to which each provides usable design knowledge.

Future directions in computer science research
John Hopcroft, Cornell University

Over the last 40 years the computer science research was focused on making computers useful. Areas included programming languages, compilers, operating systems, data structures and algorithms. These are still important topics but with the merging of computing and communication, the emergence of social networks, and the large amount of information in digital form, focus is shifting to applications such as the structure of networks and extracting information from large data sets. This talk will give a brief vision of the future and then an introduction to the science base that needs to be formed to support these new directions.

He joined the Cornell faculty in 1967, was named professor in 1972 and the Joseph C. Ford Professor of Computer Science in 1985. He served as chairman of the Department of Computer Science from 1987 to 1992 and was the associate dean for college affairs in 1993. An undergraduate alumnus of Seattle University, Hopcroft was honored with a Doctor of Humanities Degree, Honoris Causa, in 1990.

Hopcroft’s research centers on theoretical aspects of computing, especially analysis of algorithms, automata theory, and graph algorithms. He has coauthored four books on formal languages and algorithms with Jeffrey D. Ullman and Alfred V. Aho.His most recent work is on the study of information capture and access.

He was honored with the A. M. Turing Award in 1986. He is a member of the National Academy of Sciences (NAS), the National Academy of Engineering (NAE) and a fellow of the American Academy of Arts and Sciences (AAAS), the American Association for the Advancement of Science, the Institute of Electrical and Electronics Engineers(IEEE), and the Association of Computing Machinery(ACM). In 1992, he was appointed by President Bush to the National Science Board (NSB), which oversees the National Science Foundation (NSF), and served through May 1998. From 1995-98, Hopcroft served on the National Research Council’s Commission on Physical Sciences, Mathematics, and Applications.

In addition to these appointments, Hopcroft serves as a member of the Scientific Advisory Committee for the David and Lucile Packard Fellowships in Science and Engineering, the SIAM financial management committee, IIIT New Delhi advisory board, Microsoft‘s technical advisory board for research Asia, the Engineering Advisory Board, Seattle University, and the program committee for Chile Millennium Science Initiative.

Palestra: Cloud and Mobile Web-based Graphics and Visualization
segunda-feira, 10 de dezembro de 2012 às 12:53

Palestrante: Haim Levkowitz (University of Massachusetts Lowell)
Título: Cloud and Mobile Web-based Graphics and Visualization

Horário: 10:00-11:00
Local: 510 RDC

Resumo:
Cloud computing will likely be the most prevailing computing platform in the next several years. The World-Wide Web has progressed from
essentially an electronic bulletin board (with hyperlinking capabilities) to a nearly complete application platform. Cloud+Mobile, the combination of mobile computing and cloud computing, is changing how developers produce, and how users consume computing resources. Visual computing has been, and is being impacted by this same revolution.

The recent introduction of HTML5 and related graphics technologies and their rapid penetration, have made high-quality browser-based interactive graphics a reality. Where lightning fast interactivity is required, client-side rendering technologies such as SVG, Canvas, and WebGL can be employed. Where graphical “heavy lifting” is required or if client devices are too slow, rendering can take place on the server side.

Regardless of implementation details, we envision that the Cloud+Mobile platform will become the most common platform for computer graphics and visualization in the near future. Furthermore, this platform will democratize the use of advanced graphics and visualization techniques, and it stands to revolutionize mainstream data analysis using interactive visualization.

We survey the underlying technologies that enable graphics on the Cloud+Mobile platform. We discuss future challenges, and describe our own research efforts along these directions.

Seminário A Structural Approach to Indexing Triples
sexta-feira, 17 de agosto de 2012 às 14:38

Abstract. As an essential part of the W3C’s semantic web stack and linked data initiative, RDF data management systems (also known as triplestores) have drawn a lot of research attention. The majority of these systems use value-based indexes (e.g., B+-trees) for physical storage, and ignore many of the structural aspects present in RDF graphs. Structural indexes, on the other hand, have been successfully applied in XML and semi-structured data management to exploit structural graph information in query processing. In those settings, a structural index groups nodes in a graph based on some equivalence criterion, for example, indistinguishability with respect to some query workload (usually XPath). Motivated by this body of work, we have started the SAINT-DB project to study and develop a native RDF management system based on structural indexes. In this talk we present a principled framework for designing and using RDF structural indexes for practical fragments of SPARQL, based on recent formal structural characterizations of these fragments. We then explain how structural indexes can be incorporated in a typical query processing workow; and discuss the design, implementation, and initial empirical evaluation of our approach.

Seminário User Modelling on the Social Web: Twitter-based analysis for adaptation and personalisation
sexta-feira, 10 de agosto de 2012 às 15:22

Prof. Geert-Jan Houben,TU Delft, The Netherlands
In this talk, we discuss how micro-blogging activities on Twitter can be leveraged for user modeling and personalisation. We investigate this challenge and introduce a framework for user modeling on Twitter which enriches the semantics of Twitter messages (tweets) and identi es topics and entities (e.g. persons, events, products) mentioned in tweets. We analyse how strategies for constructing hashtag-based, entity-based or topic-based user profiles benefit from semantic enrichment and explore the temporal dynamics of those profiles. We further measure and compare the performance of the user modeling strategies in context of a personalised news recommendation system. Our results reveal how the different user modeling strategies impact personalization and discover that the consideration of temporal
profile patterns can improve recommendation quality. We also take a look at some applications that follow from this work, e.g. in the areas of crises management and culture-based adaptation. In the area of cultural differences we report on a study in which we analyse and compare user behaviour on two different microblogging platforms: (1) Sina Weibo which is the most popular microblogging service in China and (2) Twitter. We analyse more than 40 million microblogging activities and investigate microblogging behaviour from different angles. Our results reveal significant differences in the microblogging behaviour on Sina Weibo and Twitter and deliver valuable insights for multilingual and culture-aware user modelling based on microblogging data.
