We report on the design and construction of features of an automated query system which will assist pharmacologists who are not information specialists to access the Derwent Drug File (DDF) pharmacological database. Our approach was to first elucidate those search skills of the search intermediary which might prove tractable to automation. Modules were then produced which assist in the three important subtasks of search statement generation, namely vocabulary selection, the choice of context indicators and query reformulation. Vocabulary selection is facilitated by approximate string matching, morphological analysis, browsing and menu searching. The context of the study, such as treatment or metabolism, is determined using a system of advisory menus. The task of query reformulation is performed using user feedback on retrieved documents, thesaurus relations between document index terms and term postings data. Use is made of diverse information sources, including electronic forms of printed search aids, a thesaurus and a medical dictionary. The system will be of use both to semicasual users and experienced intermediaries. Many of the ideas developed should prove transportable to domains other than pharmacology: the techniques for thesaurus manipulation are designed for use with any hierarchical thesaurus. 相似文献

The purpose of this study was to determine if the success of students at a highly selective combined baccalaureate/MD degree program is affected by their different approaches to learning. One hundred freshmen students at the University of Missouri-Kansas City School of Medicine (UMKC) were surveyed using the Lancaster Approaches to Studying Inventory (short survey by Entwistle, 1981). Analysis of the data indicates that the learning styles of students from this combined-degree school tend to be similar to the learning styles of students from other baccalaureate-degree programs in medicine. It appears there are some relationships between approaches to learning and success in the program. This association between learning styles and success also appears to be related to gender differences.Presented at the Annual Forum of the Association for Institutional Research, Louisville, KY, May 13–16, 1990. 相似文献

The impact of cosmopolitan and local latent social roles on different professional occupations and organizational behavior has been studied since Gouldner’s seminal study was published in 1957. This study was conducted to understand the relationship between the latent social role of the public community college chief academic officer and his or her intent to pursue a community college presidency. 相似文献
