We present a simple, one-pass word alignment algorithm for parallel text. Our algorithm utilizes synchronous parsing and takes advantage of existing syntactic annotations. In our experiments the performance of this model is comparable to more complicated iterative methods. We discuss the challenges and potential benefits of using this model to train(More)
Searching is inherently a user-centered process; people pose the questions for which machines seek answers, and ultimately people judge the degree to which retrieved documents meet their needs. Rapid development of interactive systems that use queries expressed in one language to search documents written in another poses five key challenges: (1) interaction(More)

The Ektacytometer is a visco-diffractometric method to preferentially examine the functional properties of erythrocytes. The realization of this method in the form of an automated laboratory instrument, the Technicon Ektacytometer, is described. A suspension of RBC is submitted to a uniform shear stress. The resulting deformation of the cells is seen as an(More)
The ektacytometer, a device to measure erythrocyte flexibility, has been used to evaluate antisickling agents that covalently modify hemoglobin S (HbS). The instrument has been adapted to produce a continuous gradient of oxygen pressure in the measuring cuvette, which permitted the rapid determination of sickle cell rigidity over the complete oxygenation(More)
We view interactive Cross-Language Information Retrieval (CLIR) as an iterative process in which the searcher and the retrieval system collaborate to find documents that satisfy the searcher’s needs, regardless of the language in which those documents are written. Our motivation is that humans and machines can bring complementary strengths to this process.(More)
PURPOSE The aim of this study was to assess the frequency, characteristics, and financial impact of physician documentation deficiencies in abdominal ultrasound reports. METHODS Using a multi-institutional coding and billing database and natural language processing software, 12,699,502 radiology reports from 37 practices were used to identify and analyze(More)
The ektacytometer measures with precision the deformability of erythrocytes during a continuous change in oxygen tension. Automation of the instrument renders easily feasible the evaluation of proposed antisickling compounds. Drugs representative of the three modes of action presently recognized have been selected: those which increase oxygen affinity(More)
For the 2002 Cross-Language Evaluation Forum Interactive Track, the University of Maryland team focused on query formulation and reformulation. Twelve people performed a total of forty eight searches in the German document collection using English queries. Half of the searches were with user-assisted query translation, and half with fully automatic query(More)
