OBJECTIVE Identify the lexical content of a large corpus of ordinary medical records to assess the feasibility of large-scale natural language processing. METHODS A corpus of 560 megabytes of medical record text from an academic medical center was broken into individual words and compared with the words in six medical vocabularies, a common word list, and a database of patient names. Unrecogn...

Academic rankings mediate between the differing goals of the “republic of science” and of “new public management”. Nevertheless, rankings recently have come under scrutiny. We discuss the advantages and disadvantages of academic rankings, in particular, their unintended negative consequences on the research process, and conclude that academic rankings do not fulfil their intended goal. We discu...

Exam has been used enormously as an assessment tool to measure students’ academic performance in most of the higher institutions in KSA. A good quality of a set of constructed items/questions on mid and final exam would be able to measure both students’ academic performance and their cognitive skills. We adopt Rasch Model to evaluate the reliability and quality of the first mid exam questions f...

& Lexical proficiency, as a cognitive construct, is poorly understood. However, lexical proficiency is an important element of language proficiency and fluency, especially for second language (L2) learners. For example, lexical errors are a common cause of L2 miscommunication (Ellis, 1995). Lexical proficiency is also an important attribute of L2 academic achievement (Daller, van Hout, & Treffe...

The problem of the transferability of the various meanings of a polysemous word from one language to another has been studied by many researchers (e.g., Cunningham and Graham, 2000; Kellerman,1978; 1986; Viberg, 1999). The underlying theory of 'core' and 'prototype' has been used in many of psychology and psycholinguistics, such as perception (e.g. Rosch, 1973), cognitive psychology (e.g., Mill...

The research goal of this paper is to identify major academic branches and to detect research trends in design research using text mining techniques. In this paper, the information about scientific literature in design research isprocessed. A combination of clustering and bibliometric analysis led to shaping four academic branches and summarizing each academic branch. Then, research trends and ...

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...
