高校图书馆图书采购经费分配模型的改进及经费控制机制   总被引:2,自引:0,他引:2  
针对现有高校图书馆图书采购经费分配模型在经费分配点设置、影响因子选取及归属等方面的不足,提出将分配点由院系转换成学科类别,将影响因子分成院系属性和文献属性两部分并在不同步骤分别进行计算。另外针对文献受众跨越多个专业的学科类别,提出参考系数概念并给出某一学科类别参考系数的具体计算过程,建立一个更加科学的改良模型。最后针对新模型提出相应的经费控制方法,使新模型更具实际操作性和现实意义。  相似文献

基于粗糙集加权的文本分类方法研究   总被引:6,自引:0,他引:6  
文本自动分类是当前智能信息处理中一类重要的研究课题。本文分析了基于统计理论的文本分类的基本特点,提出采用可变精度粗糙集模型中的分类质量构造新的特征词权重计算公式。这种新的加权方法,相对于广泛使用的逆文本频率加权方法,大大改进了文本样本在整个空间中的分布,使得类内距离减少,类间距离增大,在理论上将提高样本的可分性。最后利用支持向量机和K近邻两种分类器,验证了这种新的加权方法对分类效果确实有所提高。  相似文献

Online display advertising is a multi-billion dollar industry where advertisers promote their products to users by having publishers display their advertisements on popular Web pages. An important problem in online advertising is how to forecast the number of user visits for a Web page during a particular period of time. Prior research addressed the problem by using traditional time-series forecasting techniques on historical data of user visits; (e.g., via a single regression model built for forecasting based on historical data for all Web pages) and did not fully explore the fact that different types of Web pages and different time stamps have different patterns of user visits. In this paper, we propose a series of probabilistic latent class models to automatically learn the underlying user visit patterns among multiple Web pages and multiple time stamps. The last (and the most effective) proposed model identifies latent groups/classes of (i) Web pages and (ii) time stamps with similar user visit patterns, and learns a specialized forecast model for each latent Web page and time stamp class. Compared with a single regression model as well as several other baselines, the proposed latent class model approach has the capability of differentiating the importance of different types of information across different classes of Web pages and time stamps, and therefore has much better modeling flexibility. An extensive set of experiments along with detailed analysis carried out on real-world data from Yahoo! demonstrates the advantage of the proposed latent class models in forecasting online user visits in online display advertising.  相似文献

TF-IDF是一种常用的文本特征选择方法。基于该模型的特征选择思想,以特征项的类内分布、类间分布信息为依据,通过引入类内分布及类间分布权重因子对模型的TF及IDF部分进行加权,提出一种基于类别分布信息的文本特征选择模型。新模型使得TF部分含有类内文本频数信息,同时IDF部分含有特征项的类间频数信息。随后的文本分类试验表明,平均查全率、查准率分别提高6.4%、7.8%,F1值提高约7%,验证了本研究提出的基于类别分布的文本特征选择模型的有效性。  相似文献

弱势群体利用图书馆这个公共教育平台、分享社会知识资源是每个公民的政治权利。保证社会各阶层获取知识权利的均等,是我们推行民主政治的体现。知识公平思想、社会求助思想在古代社会就已经萌芽。孔子在教育对象上主张“有教无类”,在教育目标上提出了培养和造就高素质的“君子”,即素质教育。先秦子书《管子》对社会救助有系统的论述。古代先哲们追求知识公平和弱势群体救助的思想与实践,不仅对中国文化事业的发展产生了深远的历史影响,而且对今天的弱势群体的图书馆知识援助也有一定的启迪价值。参考文献9。  相似文献

In many realistic settings of expert finding, the evidence for expertise often comes from heterogeneous knowledge sources. As some sources tend to be more reliable and indicative than the others, different information sources need to receive different weights to reflect their degrees of importance. However, most previous studies in expert finding did not differentiate data sources, which may lead to unsatisfactory performance in the settings where the heterogeneity of data sources is present. In this paper, we investigate how to merge and weight heterogeneous knowledge sources in the context of expert finding. A relevance-based supervised learning framework is presented to learn the combination weights from training data. Beyond just learning a fixed combination strategy for all the queries and experts, we propose a series of discriminative probabilistic models which have increasing capability to associate the combination weights with specific experts and queries. In the last (and also the most sophisticated) proposed model, the combination weights depend on both expert classes and query topics, and these classes/topics are derived from expert and query features. Compared with expert and query independent combination methods, the proposed combination strategy can better adjust to different types of experts and queries. In consequence, the model yields much flexibility of combining data sources when dealing with a broad range of expertise areas and a large variation in experts. To the best of our knowledge, this is the first work that designs discriminative learning models to rank experts. Empirical studies on two real world faculty expertise testbeds demonstrate the effectiveness and robustness of the proposed discriminative learning models.  相似文献

Co-streaming classes have enabled library staff to extend open classes to distance education students and other users. Student evaluations showed that the model could be improved. Two areas required attention: audio problems experienced by online participants and staff teaching methods. Staff tested equipment and adjusted software configuration to improve user experience. Staff training increased familiarity with specialized teaching techniques and troubleshooting procedures. Technology testing and staff training were completed, and best practices were developed and applied. Class evaluations indicate improvements in classroom experience. Future plans include expanding co-streaming to more classes and on-going data collection, evaluation, and improvement of classes.  相似文献

ABSTRACT

Libraries have been struggling for years to move beyond 1-shot library training. In spite of efforts in the last decade to promote information literacy for undergraduate and graduate students alike, libraries more often than not are still not reaching the goals articulated in the Association of College & Research Libraries's information literacy standards. The problems are compounded when institutions serve students who also happen to be taking part or all of their classes online or at field-based sites. The model for providing a library training program for students in the Doctor of Education (EdD) program in a distance program focuses on providing students with training that builds sequentially and developmentally at the points of need for students in the 1st year of classes and provides additional support for students once they have completed their course work. This multistepped approach is designed to help doctoral students throughout the doctoral process.  相似文献
