Modeling Extemporaneous Elaboration

چکیده
Intelligent problem solving systems must be able to express their results in a coherent and flexible manner. One way this can be done is by eztemporaneous elaboration, the method of language production that underlies more skilled tasks such as explanation. This paper outlines a computational model for extemporaneous elaboration that is implemented in a computer model called Extemper, shows examples of its operation, and compares it with other models of language production. Extemper contains the four components minimally required for elaboration: 1) an efficient method for linearizing a knowledge structure, 2) a translation/selection mechanism for producing a conceptual textbase from the knowledge structure, 3) local coherence operators which provide local connections between textbase elements, and 4) a conceptual generator to translate the coherent textbase into English.

BACKGROUND Administration of medications to pediatric patients is challenging because many drugs are not commercially available in appropriate dosage formulations and/or strengths. Consequently, these drugs are prepared extemporaneously as oral liquid (OL) formulations using marketed tablets or capsules. In many cases, the stability of these extemporaneous preparations, which may affect their t...

Oncology pharmacists face a constant challenge with patients who cannot swallow oral anticancer drugs, making extemporaneous oral liquid preparation a requirement. Improper extemporaneous preparation of these agents, especially with the traditional chemotherapy with a narrow therapeutic index, may increase the risk of over- or underdosing. In community pharmacies, multiple barriers exist that p...

This study investigated the effect of using visual aids, semantic elaboration, and visual aids plus semantic elaboration on the Iranian EFL learners' vocabulary learning. To conduct the study, the researchers assigned 49 elementary learners to three homogeneous groups according to their proficiency level. Then, a pre-test of Paribakht and Wesche's Vocabulary Knowledge Scale was given to each gr...
