Infective endocarditis (IE) causes substantial morbidity and mortality despite modern antimicrobial chemotherapy and advances in the ability to diagnose and treat complications. Prevention of IE is, therefore, very important. Infective endo-carditis usually develops following a bacteraemia in individuals with underlying structural cardiac defects. Bacteraemia may occur spontaneously, follow eve...

Public choice ana lysis of voting predicts apathy and rational ignorance. Transactions cost analysis forms predictions on the basis of systematic responses to low-cost signals that serve to reduce decision-making costs. Public choice analysis is premised only on instrumental rationality; a transactions cost analysis includes analysis of intrinsic motivation, ie. analysis of 'consumption' benefi...

Relation Discovery discovers predicates (relation types) from a text corpus relying on the co-occurrence of two named entities in the same sentence. This is a very narrowing constraint: it represents only a small fraction of all relation mentions in practice. In this paper we propose a high recall approach for predicate extraction which enables covering up to 16 times more sentences in a large ...

ILQUA first participated in TREC QA main task in 2003. This year we have made modifications to the system by removing some components with poor performance and enhanced the system with new methods and new components. The newly built ILQUA is an IE-driven QA system. To answer “Factoid” and “List” questions, we apply our answer extraction methods on NE-tagged passages. The answer extraction metho...

This paper presents new Information Extraction scenarios which are linguistically and structurally more challenging than the traditional MUC scenarios. Traditional views on event structure and template design are not adequate for the more complex scenarios. The focus of this paper is to show the complexity of the scenarios, and propose a way to recover the structure of the event. First we ident...

BACKGROUND: Infective endocarditis (IE) was a significant cause of morbidity and mortality, particularly in children with congenital heart disease (CHD). could occur all ages higher below 1-year-old, including neonates. Various clinical manifestations IE make it difficult to prompt diagnosis appropriate management. Finding echocardiography help clinicians determine the IE. Systemic embolization...

Background and Purpose Cost-effectiveness analyses of stroke management are hampered by paucity of economic data. We made an update of the direct and indirect costs of stroke in Sweden (population, 8.5 million). Methods Direct costs (ie, the costs for hospital and outpatient care and social services) were estimated on the basis of two prospective population-based studies of stroke and of two na...
