TALON--the first five years.     

D D Hendricks 《Bulletin of the Medical Library Association》1976,64(2):203-211

The South Central Regional Medical Library Program, Region IX in the national network of medical libraries, was one of the last to be organized and funded. The particular makeup of this organization has permitted a good deal of flexibility in the identification and implementation of various types of network services and activities. The following is a brief account of some of these network functions during the first five years relating the successes and failures in network strategies and describing the further evolution of programs and refinement of a regional plan which will advance network services.  相似文献   

‘The feeling of exclusion’: Young peoples' perceptions of art galleries     

David D.M. Mason  Conal McCarthy 《Museum Management and Curatorship》2006,21(1):20-31

This article first looks at the relationship between museums and art galleries and their potential audiences and, in particular, the under-represented sector of young visitors. It examines the main findings from the limited research available on young visitors, and goes on to discuss theories delineating the differences between the cultures, identities and values of culture consumers and culture providers. The second part of the article looks at what specific museums have done towards being more inclusive in their appeal, and then reports the findings of a survey of young people in relation to New Zealand's Auckland Art Gallery. The survey found that young people's ideas of what constitutes modern, relevant art do not match standard art criteria, and that most exhibitions and marketing methods do not mesh with their worldview. The article concludes by using data from the survey to suggest ways of engaging more young people with public art galleries.  相似文献   

Construction of query concepts based on feature clustering of documents     

Youjin Chang  Minkoo Kim  Vijay V. Raghavan 《Information Retrieval》2006,9(3):231-248

In Information Retrieval, since it is hard to identify users’ information needs, many approaches have been tried to solve this problem by expanding initial queries and reweighting the terms in the expanded queries using users’ relevance judgments. Although relevance feedback is most effective when relevance information about retrieved documents is provided by users, it is not always available. Another solution is to use correlated terms for query expansion. The main problem with this approach is how to construct the term-term correlations that can be used effectively to improve retrieval performance. In this study, we try to construct query concepts that denote users’ information needs from a document space, rather than to reformulate initial queries using the term correlations and/or users’ relevance feedback. To form query concepts, we extract features from each document, and then cluster the features into primitive concepts that are then used to form query concepts. Experiments are performed on the Associated Press (AP) dataset taken from the TREC collection. The experimental evaluation shows that our proposed framework called QCM (Query Concept Method) outperforms baseline probabilistic retrieval model on TREC retrieval.  相似文献

Analysis of Statistical Question Classification for Fact-Based Questions   总被引：1，自引：0，他引：1  

Donald Metzler  W. Bruce Croft 《Information Retrieval》2005,8(3):481-504

Question classification systems play an important role in question answering systems and can be used in a wide range of other domains. The goal of question classification is to accurately assign labels to questions based on expected answer type. Most approaches in the past have relied on matching questions against hand-crafted rules. However, rules require laborious effort to create and often suffer from being too specific. Statistical question classification methods overcome these issues by employing machine learning techniques. We empirically show that a statistical approach is robust and achieves good performance on three diverse data sets with little or no hand tuning. Furthermore, we examine the role different syntactic and semantic features have on performance. We find that semantic features tend to increase performance more than purely syntactic features. Finally, we analyze common causes of misclassification error and provide insight into ways they may be overcome.  相似文献

Disciplined freedom,branded authenticity,and dependable independence: how tensions enact flexibility in lifestyle blogging careers     

Ziyu Long  Elizabeth D. Wilhoit 《Journal of Applied Communication Research》2018,46(3):368-387

Analyzing 219 blog posts from 52 self-employed women lifestyle bloggers in North America, this study shows how these digital professionals navigate tensions and communicatively constitute work flexibility. In their narratives, women bloggers employed tension management approaches such as reframing, continual connections, and reflective practice in response to tensions in enacting temporal–spatial, identity, and financial flexibility. Specifically, women followed oxymoronic constructions – disciplined freedom, branded authenticity, and dependable independence – to embrace and transform competing poles of fluidity?structure, authenticity?marketability, and independence?interconnection. Expanding work–life research to the self-employed digital labor context, this study responds to recent calls to uncover more-than tension management strategies in empirical settings and contributes to a tension-centered, contextual, and processual analysis of workplace flexibility construction.  相似文献
