In Korean information retrieval, compound nouns play an important role in improving precision in search experiments. There are two major approaches to compound noun indexing in Korean: statistical and linguistic. Each method, however, has its own shortcomings, such as limitations when indexing diverse types of compound nouns, over-generation of compound nouns, and data sparseness in training. In this paper, we propose a corpus-based learning method, which can index diverse types of compound nouns using rules automatically extracted from a large corpus. The automatic learning method is more portable and requires less human effort, although it exhibits a performance level similar to the manual-linguistic approach. We also present a new filtering method to solve the problems of compound noun over-generation and data sparseness. 相似文献

Managed care poses numerous opportunities and challenges for today's health care organizations and their employees. This article investigates the ways that hospital nurses develop and make sense of their professional roles and organizational environments in a changing and often uncertain managed care setting. The case study approach used in this research combined qualitative methodologies to gain a rich, detailed, and contextual understanding of nurses' work roles and organizational experiences. After an analysis of interviews with 24 nurses and observations of nurses' communicative activities on one inpatient unit, the complexity of sensemaking and role development in a managed care environment is considered. Conclusions are then drawn regarding the theoretical and pragmatic implications of nurses' communicative processes, as they attempted to develop and understand their roles in a changing organizational context. 相似文献

The poor reading achievement of African-American children in urban schools is well established. African-American children from low-income homes may be at particular risk for reading difficulties, although middle-income children often fare poorly as well. Intervention efforts have focused on children in kindergarten through fifth grade. This article suggests that prevention efforts must begin prior to kindergarten entry. Several key variables that may influence young children's performance, including poverty, general oral language skills, dialectal variations, home literacy practices, standardized testing bias, and teacher expectations, are explored. Future directions for research addressing emergent literacy in African-American children are discussed throughout. 相似文献

In 2001, the Regenstrief Institute for Health Care and the Indiana University School of Medicine (IUSM) began an IAIMS planning effort to create a vision and a tactical plan for the first Integrated Advanced Information Management Systems (IAIMS) implementation to cross a large area and include unaffiliated institutions. A number of elements made this planning effort unique. Among these elements were the existence of a network infrastructure that supported the Indianapolis Network for Patient Care, the existence of a mature medical informatics program at the Regenstrief Institute, and the existence of a wide-area knowledge network fostered by the IUSM libraries. However, the leadership for a strong information technology role in the IUSM that could promote collaboration in support of education and research across the diverse Indianapolis hospital systems had been lacking. By bringing together various groups, each with a commitment to improve health care quality and public health across the Indianapolis metropolitan area, regardless of individual institutional affiliation, the strategic directions for I3-Indianapolis IAIMS Initiative have been defined and the foundations for a third generation IAIMS construct have been laid in Indianapolis, Indiana. 相似文献

Currently, about ten Goryeo dynasty (918–1392 CE) sutra boxes are preserved in museums in Korea, Japan, the United States, the Netherlands, and the United Kingdom. This article is the result of an examination of a sutra box in the collection of the Rijksmuseum, Amsterdam (hereafter ‘Rijksmuseum sutra box’), which was first introduced to a European audience in the Transactions and Proceedings of the Japanese Society, in 1913–1914. The Rijksmuseum sutra box differs from other Goryeo sutra boxes. With its altered structure and modified motifs, this box bears significant value, not only for the research of thirteenth-century Goryeo mother-of-pearl art, but also for the study of cross-cultural adaptations in East Asian lacquer art. This article investigates the date of manufacture of the sutra box by analysing the manufacturing techniques and its various original and modified parts. For this, an X-ray radiograph was carried out for the first time. As a result, discoveries have been made regarding the structure and decoration of the lower part, which has been modified and is different from Goryeo mother-of-pearl sutra boxes. Finally, this paper reconsiders conservation and repair of Goryeo sutra boxes, as illuminated by an understanding of the original and repaired parts of this box. 相似文献
