In this paper we describe our participation in INEX 2009 in the Ad Hoc Track, the Book Track, and the Entity Ranking Track. In the Ad Hoc track we investigate focused link evidence, using only links from retrieved sections. The new collection is not only annotated with Wikipedia categories, but also with YAGO/WordNet categories. We explore how we can use both types of category information, in t...

In this paper, we describe a trust mechanism that is implemented with an agent facilitator, which is a typical mechanism for mediating agents in multi-agent systems. Although many facilitators are based on tracking the capabilities of each agent, they do not track the dynamic relationships between participants necessary for ecommerce, most especially that of trust. We propose to add a trust mod...

Today human performance on search tasks and information retrieval evaluation metrics are loosely coupled. Instead, information retrieval evaluation should be a direct prediction of human performance rather than a related measurement of ranked list quality. We propose a TREC track or other group effort that will collect a large amount of human usage data on search tasks and then measure particip...

Este estudo descreve as mudanças na especiação de Hg nas águas da Baía de Sepetiba, SE, Brasil, ao longo do gradiente estuarino, durante eventos de maré em diferentes estações. A avaliação química das águas da baía indicou uma exportação de material particulado em suspensão (MPS) pobre em carbono orgânico para a plataforma continental adjacente, principalmente durante a estação chuvosa e uma im...

Nos ultimos anos, vêm se acumulando as evidências sobre a necessidade de vanádio dos organismos mais evoluídos. Estudos de compostos modelos constituem-se numa importante ferramenta para o entendimento dos diferentes aspectos da bioquímica deste bioelemento. Neste artigo, apresentamos os resultados dos nossos estudos, assim como os de outros grupos de pesquisa, sobre compostos modelos relaciona...

In an observational study using an eye-tracker, subjects were presented with a modeless cookie choice dialog preceding a short survey on Internet privacy. Subjects were later asked whether they believed ad trackers were present on the site or not. 41% believed there either were or were not ad trackers on the site based on not clicking ”allow” or ”block”, respectively. These results suggest that...

Adversarial decision making is a particular type of decision making problem where the gain a decision maker obtains as a result of his decisions is affected by the actions taken by others. Representation of alternatives’ evaluations and methods to find the optimal alternative are two important aspects in the adversarial decision making. The aim of this study is to develop a general framework fo...

A study by Burkle et al. in BMC Anesthesiology examined attitudes around perioperative do-not-resuscitate orders. Questionnaires were given to patients, as well as to anesthesiologists, internists and surgeons. The study has limitations and is open to interpretation. However, the findings are important. There appear to be attitudinal differences between patients and doctors, and between special...
