网络信息检索结果的相关性差、信息过载等问题严重影响了用户的利用效率,基于交流互动基础的合作信息检索模式便成为关注的重点。国外对其的研究多集中于合作信息检索的理论;国内对合作信息检索的研究为数不多,集中于国外的合作信息检索、合作信息检索的演化研究,只有少数学者对合作信息检索的模型、系统构建、运行机制进行了研究,其理论与应用研究都有待深入。 相似文献

The Veterans Administration Library Network (VALNET) needed an automated library system that could interface with the agency's national automation activities. The Library Special Interest Users Group was established to oversee the selection of appropriate automated systems. The Massachusetts General Hospital Utility Multi-Programming System (MUMPS) computer language and VA FILEMAN, a database management system, are being used to create new library software, which will be in the public domain. 相似文献

This research investigated the influence of message framing (gain or loss) and temporal distance (present or future) on the intention of Human papillomavirus (HPV) vaccination. A total of 156 Chinese undergraduates participated in a controlled experiment in Macau, a Special Administrative Region of China. Results showed that message framing and temporal distance interacted to impact the intention of HPV vaccination. Particularly, among participants who had no prior knowledge of HPV vaccine, the gain-present and loss-future framed messages resulted in more positive attitudes toward the message, higher degree of perceived severity of HPV infection, and more likelihood to get HPV vaccination than the gain-future and loss-present framed messages. Implications of the findings were discussed. 相似文献

An assessment of the condition of nine engraved sites in the Hong Kong Special Administrative Region
Nine engravings in the hinterland around Hong Kong Island have been studied independently by the authors, as part of an overall assessment of current management practices, the state of the engravings, conservation impacts and future survival. Four independent studies were commissioned in 2009 by the Hong Kong Heritage Museum in conjunction with the Antiquities and Monuments Office who have legislative responsibility for all archaeological sites within the Hong Kong Special Administrative Region. The sites have received varying levels of protection in the form of roofs, fences, and screens, and in more recent times, a range of conservation treatments aimed at prolonging their life and improving legibility. This paper reviews the state of the engravings from the point of view of protection and presentation and considers the effectiveness of the infrastructure in mitigating what are often conflicting needs. Modern conservation treatments must be considered in several dimensions: their effectiveness and durability in an aggressive climate, given that the engravings have survived for 3000 years, and the feasibility and cost of maintaining such treatments over the next 3000 years and longer. This paper describes field observations rather than measured data, due to the nature of the commission, highlighting the value of intelligent observation as an investigative tool. The main focus of the paper is on the impact of protective shelters and applied treatments as observed during two of the independent surveys, concluding that protection must address all environmental and visitor impacts to be fully protective. 相似文献
