Efficient implementation of associative classifiers for document classification     

Yongwook Yoon  Gary Geunbae Lee 《Information processing & management》2007

In practical text classification tasks, the ability to interpret the classification result is as important as the ability to classify exactly. Associative classifiers have many favorable characteristics such as rapid training, good classification accuracy, and excellent interpretation. However, associative classifiers also have some obstacles to overcome when they are applied in the area of text classification. The target text collection generally has a very high dimension, thus the training process might take a very long time. We propose a feature selection based on the mutual information between the word and class variables to reduce the space dimension of the associative classifiers. In addition, the training process of the associative classifier produces a huge amount of classification rules, which makes the prediction with a new document ineffective. We resolve this by introducing a new efficient method for storing and pruning classification rules. This method can also be used when predicting a test document. Experimental results using the 20-newsgroups dataset show many benefits of the associative classification in both training and predicting when applied to a real world problem.  相似文献

No room at the top? The glass wall for professional services managers in pre-1992 English universities     

Sue Shepherd 《Perspectives: Policy and Practice in Higher Education》2017,21(4):129-134

Pre-1992 English universities are changing the way they appoint their deputy and pro-vice-chancellors (PVCs). Traditionally, PVC posts were filled by internal secondment from within the professoriate, but these days an increasing number are appointed by means of external open competition involving advertisement and/or executive search. So has this ‘opening up’ of PVC positions created new career progression opportunities for professional services managers? Findings from a census, online survey and interviews with a range of senior university managers suggest not. Despite the PVC role becoming more managerial, those getting the jobs remain overwhelmingly career academics. Professional services managers confront a glass wall, excluded from consideration by a non-negotiable requirement for academic credibility. Aware they have little chance of getting a PVC job, they are unlikely to apply. The continued monopolisation of PVC posts by academic managers represents a form of social closure that serves to maintain their elite status.  相似文献   

美英中三国大学校长遴选制度的比较研究   总被引：1，自引：0，他引：1  

明薪 《煤炭高等教育》2007,25(1):68-71

影响美英两国大学校长遴选的因素主要有“教授治校”传统、高等教育价值观以及高等教育中权力的配置。从任职条件和选拔程序来看,美英两国大学校长在选拔制度上既有共同点也有不同点。中国高校校长的遴选多采用任命制,其标准和程序套用选拔党政干部方式。依据国家的政治经济制度、文化传统及大学的发展规律,我国大学校长的遴选需要完善遴选程序的可操作层面技术,并优化大学校长遴选的社会环境。  相似文献
