Brazil will host the FIFA World Cup™, the biggest single-event competition in the world, from June 12-July 13 2014 in 12 cities. This event will draw an estimated 600,000 international visitors. Brazil is endemic for dengue. Hence, attendees of the 2014 event are theoretically at risk for dengue. We calculated the risk of dengue acquisition to non-immune international travellers to Brazil, depe...

The results of recent studies on prediction markets are encouraging. Prior experience demonstrates that markets with different incentive schemes predicted uncertain future events at a remarkable accuracy. In this paper, we study the impact of different monetary incentives on the prediction accuracy in a field experiment. In order to do so, we compare three groups of users, corresponding to thre...

The 2010 FIFA World Cup took place in South Africa between 11 June and 11 July 2010. The European Centre for Disease Prevention and Control (ECDC), in collaboration with the hosting authorities, carried out enhanced epidemic intelligence activities from 7 June to 16 July 2010 for timely detection and monitoring of signals of public health events with a potential to pose a risk to participants a...

More than 600,000 football fans, coming from all over the world, were expected to visit Brazil during the FIFA World Cup 2014. International travel can become a public health problem when the visitors start to become sick, needing medical intervention and eventually hospitalization. The occurrence of dengue fever infections in Brazil is persistent and has been increasing since the 1980s, and th...

The aim of the study was to analyse the inter-individual differences concerning the velocities at which changes in movement pattern occurred. During the FIFA World Cup Final in 2006 20 players were observed. For every player the individual velocity boarders were obtained for the movement patterns walking, jogging, cruising and sprinting. Comparisons were done between common velocity boarders an...

This paper presents the usage of a general domain-independent data mining system in discovering of the Web user access patterns. DB2 Intelligent Miner for Data was successfully used in data mining of a huge Web log which was collected during the World FIFA Cup 1998. The clustering, associations and sequential pattern mining functions were considered in the context of Web usage mining. The clust...

Traditional clustering algorithms are deterministic in the sense that a given dataset always leads to the same output partition. This paper modifies traditional clustering algorithms whereby data is associated with a probability model, and clustering is carried out on the stochastic model parameters rather than the data. This is done in a principled way using a Bayesian approach which allows th...

This paper is concerned with three elemental game progress patterns. It is found that each of the three games in 2010 FIFA World Cup, Group E is a combination of the elemental progress patterns. It is confirmed that the analysed Soccer and Chess games are a combination of the elemental game progress patterns. It is suggested that this finding is universal for all games. Time history of informat...

The employment of psychological measurement,attention, alleviates the semantic uncertainty around video events and leads to an effective general event detection approach. This paper proposes a multi-resolution autoregressive framework to estimate a unified attention curve from multi-modality salient features at different temporal resolutions. The highlights of this work are: (1) the capability ...

This paper presents a detailed characterisation of user behaviour for a series of interactive sport videos from the 2006 FIFA World Cup. In addition to generic VCR-like features, our custom-built Video-on-Demand architecture enabled us to provide advanced interactivity features such as bookmarking. We illustrate how such functionality may have a dramatic impact on how users consume content. A d...
