We describe a utility evaluation to determine whether cross-document information extraction (IE) techniques measurably improve user performance in news summary writing. Two groups of subjects were asked to perform the same time-restricted summary writing tasks, reading news under different conditions: with no IE results at all, with traditional singledocument IE results, and with cross-document...

Ischemic stroke is a common complication of infective endocarditis (IE), occurring in 20-40% of left side IE cases. In these subsets, anticoagulation therapy may provoke hemorrhagic transformation (HT) of ischemic stroke, and complications of this magnitude deteriorate the clinical course for IE patients. However, in cases of IE complicated with a mechanical prosthetic valve, the physician can ...

The movement for a national pharmacare plan in Canada is growing, but at the same time the multinational pharmaceutical companies and their supporters are critical of such a move. The three major arguments that they make are that all that is needed is to “fill in the gaps,” ie, cover those who currently are uninsured or underinsured, that private drug plans are superior to public ones because t...

CONTEXT Limited data exist regarding population-based epidemiologic changes in incidence of infective endocarditis (IE). OBJECTIVE To evaluate temporal trends in the incidence and clinical characteristics of IE. DESIGN, SETTING, AND PATIENTS Population-based survey using the resources of the Rochester Epidemiology Project of Olmsted County, Minnesota. One hundred seven IE episodes occurred ...

1.2 Machine failure A system is composed of 5 components, each of which is either working or broken. Consider an experiment that consists of observing the status of each component, and let the outcome of the experiment be given by the vector (x1, x2, x3, x4, x5), where xi = 1 if component i works and 0 if component i is broken. 1. How many outcomes are in the sample space of this experiment? 2....

Neoplastic transformation is a complex process that results from multiple changes in gene activities. Probably most of these are mutational, i.e. alterations in the genomic structure of DNA, but others may be due to adaptive changes wherein genes are expressed that are inappropriate to a stage of development or differentiation. In this commentary neoplastic development is discussed in the conte...

le mouvement transversal de la locomotive ou des wagons , appele ie lacet, provient de deux causes principales: -la conicite des bandages -les irregularites de la voie dans ie plan horizontal. on se propose ici d'etudier la premiere cause , ce qui nous conduit a une equation differentielle non lineaire du deuxieme ordre. • l'equation en question est etudiee dans plusieurs cas difftten...

We design and release BONIE, the first open numerical relation extractor, for extracting Open IE tuples where one of the arguments is a number or a quantity-unit phrase. BONIE uses bootstrapping to learn the specific dependency patterns that express numerical relations in a sentence. BONIE’s novelty lies in task-specific customizations, such as inferring implicit relations, which are clear due ...

AIMS Existing risk models in infective endocarditis (IE) have not investigated whether the prognostic value of clinical parameters is time-dependent. We have explored the potential of time-dependent risk stratification to predict outcome in IE. METHODS AND RESULTS We studied 273 patients admitted with IE to two centres (derivation cohort n=192, validation cohort n=81). The derivation cohort w...
