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.
