关于中国武术文化形态及演变的研究

中国武术文化形态源远流长,有着与其它国家武术迥然不同的发展过程和特点,既是中国文化的缩影,又在自身发展的历程中,受到中国哲学、礼乐文化、医学养生、军事谋略、戏曲文学、审美艺术等等因素的影响.中国武术发展至今,有其复杂的历史和文化背景, 自身面临着许多问题和冲突.既因袭着传统,又向往着未来;既萌动了世界意识,又依托着民族情感.一方面保留着传统武术的品质和形态特征,另一方面又增加了一些现代体育的内涵.只有正确认识武术文化形态及演变,才能在时代背景下,保存其文化主脉的同时,以博大的气派,不断融汇和吸纳其它文化元素,使其进一步发展并保持活力.     

高校田径教学改革的新思路

分析当前高校田径教学存在的主要问题及其原因，讨论田径教学对大学生进行全面素质教育的重要作用。根据高校体育教改的发展趋势，提出高校田径教学改革的新思路：突出素质教育，重新确立田径教学的重要地位；结合体质健康测试，把田径练习贯穿于各项体育课程中；深化教学与评价方法改革，调动学生练习田径的积极性；发挥教育者的主导作用，加强对学生的教育和管理。     

普通高校田径运动员力量训练的研究

训练对象的不同,力量训练的方法与手段等存在明显差异。普通高校田径运动员力量基础的薄弱性、力量训练的短期效益性,以及训练计划的频繁变更性等决定了其力量训练不能机械地照搬专业队的训练模式和训练方法。本文主要运用文献资料法,对普通高校田径运动员力量训练的特点进行深入地分析,并在此基础上提出了普通高校田径运动员力量训练必须遵循的六条原则和四种训练方法,以供广大教练员参考之用。     

人与生产力

历史是通过人的活动创造的，历史又有着自己的规律，人是在自己意识支配下活动的，历史却并不完全遵照人的意识。马克思主义不到人以外寻找历史规律，却又把人置于历史规律即生产力发展进程之中。人是生产力的创造者，生产力又创造着人。     

A Corpus-Based Learning Method of Compound Noun Indexing Rules for Korean

In Korean information retrieval, compound nouns play an important role in improving precision in search experiments. There are two major approaches to compound noun indexing in Korean: statistical and linguistic. Each method, however, has its own shortcomings, such as limitations when indexing diverse types of compound nouns, over-generation of compound nouns, and data sparseness in training. In this paper, we propose a corpus-based learning method, which can index diverse types of compound nouns using rules automatically extracted from a large corpus. The automatic learning method is more portable and requires less human effort, although it exhibits a performance level similar to the manual-linguistic approach. We also present a new filtering method to solve the problems of compound noun over-generation and data sparseness.     

Measuring Search Engine Quality

The effectiveness of twenty public search engines is evaluated using TREC-inspired methods and a set of 54 queries taken from real Web search logs. The World Wide Web is taken as the test collection and a combination of crawler and text retrieval system is evaluated. The engines are compared on a range of measures derivable from binary relevance judgments of the first seven live results returned. Statistical testing reveals a significant difference between engines and high intercorrelations between measures. Surprisingly, given the dynamic nature of the Web and the time elapsed, there is also a high correlation between results of this study and a previous study by Gordon and Pathak. For nearly all engines, there is a gradual decline in precision at increasing cutoff after some initial fluctuation. Performance of the engines as a group is found to be inferior to the group of participants in the TREC-8 Large Web task, although the best engines approach the median of those systems. Shortcomings of current Web search evaluation methodology are identified and recommendations are made for future improvements. In particular, the present study and its predecessors deal with queries which are assumed to derive from a need to find a selection of documents relevant to a topic. By contrast, real Web search reflects a range of other information need types which require different judging and different measures.
