The large-scale applicability of knowledge-based information access systems such as the ones based on Information Extraction techniques strongly depends on the possibility of automatically acquiring the large amount of knowledge required. However, the basic assumption of the IE paradigm, i.e. that the information need is known in advance, limits inherently its applicability since the resulting ...

As a participating national lab in the inter-institutional effort to resolve performance issues of the non-elutable ion exchange technology for Cs extraction, we have carried out a series of characterization studies of UOP IONSIV IE-911 and its component parts. IE-911 is a bound form (zirconium hydroxide-binder) of crystalline silicotitanate (CST) ion exchanger. The crystalline silicotitanate r...

BACKGROUND With the increasing incidence of asthma, there is increasing concern over environmental exposures that may trigger asthma exacerbations. Blooms of the marine microalgae, Karenia brevis, cause red tides (or harmful algal blooms) annually throughout the Gulf of Mexico. K brevis produces highly potent natural polyether toxins, called brevetoxins, which are sodium channel blockers, and p...

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...

This paper reports the results of applying digital image analysis in conjunction with statistical pattern recognition to measure the size and shape features of various seed types and to classify them into the primary grain, small seed, and large seed categories. Th...

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...
