In this work, we present the first quality flaw prediction study for articles containing the two most frequent verifiability flaws in Spanish Wikipedia: articles which do not cite any references or sources at all (denominated Unreferenced) and articles that need additional citations for verification (so-called Refimprove). Based on the underlying characteristics of each flaw, different state-of-the-art approaches were evaluated. For articles not citing any references, a well-established rule-based approach was evaluated and interesting findings show that some of them suffer from Refimprove flaw instead. Likewise, for articles that need additional citations for verification, the well-known PU learning and one-class classification approaches were evaluated. Besides, new methods were compared and a new feature was also proposed to model this latter flaw. The results showed that new methods such as under-bagged decision trees with sum or majority voting rules, biased-SVM, and centroid-based balanced SVM, perform best in comparison with the ones previously published.  相似文献   

高中篮球模块教学的实践与探索     

赵旭 《当代体育科技》2020,(12):76-77

随着体育的发展,模块教学理念深入学校的体育教学之中。模块教学是以学生为主体的教学模式,学生能够根据自己的特长和爱好选择适合自己的体育运动项目,从而保障了学习体育的积极性。针对于今天的教学来说,教师的教学目的一定不是单纯地去追求学生的学习成绩,今天随着新课标的不断深入,教师需要把以往从学生纯净的追求转变为对于学生综合素养的追求。这个时候体育学科的重要性就会有所体现,身体是革命的本钱,学生在学习的过程中一定要有一个好的身体素质,只有这样他们才能够更好地应对接下来的生活。  相似文献   

Medieval and renaissance glass technology in Valdelsa (Florence). Part 1: raw materials, sands and non-vitreous finds     

U. Casellato  F. Fenzi  P. Guerriero  S. Sitran  P. A. Vigato  U. Russo  M. Galgani  M. Mendera  A. Manasse 《Journal of Cultural Heritage》2003,4(4):337-353

A significant number of archaeological finds of the 13th–16th century from the Tuscan sites of Germagnana and Gambassi in Valdelsa—FI, was studied by different physico-chemical investigations (SEM–EDS, ICP, Mössbauer spectroscopy, XRD, XRF, TG-DTA) in order to contribute to clarify the production methodology and the pre-industrial glass manufacture technology. The studied samples are mainly non-vitreous finds as production waste, refractory materials, crucibles and raw materials; also vitreous finds as frits, skims, glasses (glass masses, glass working waste and finished products) have been taken into consideration. The obtained petrographic and physico-chemical data strongly suggest that both Gambassi and Germagnana glass manufactures were strictly connected with the sources of vitrifiable materials, situated in Tuscan sand quarries. In particular a comparison between sands from the neighbouring quarries and appropriate finds of the two archaeological sites evidences that the employed vitrifiable materials possibly belong to La Casina La Cava resort. The archaeological classification, based on macroscopic observation and stratigraphic position, was compared and verified with the scientific classification of the examined finds of Germagnana and Gambassi sites based on their composition, morphology and physico-chemical properties.  相似文献
