实践教学环节的质量评价体系平台的研究

高职高专院校实践教学环节是高职高专教学中的一个非常重要的组成部分 ,它直接关系到能否实现高职高专教育人才培养目标。目前大多数高职高专院校对实践教学环节开始重视 ,但对实践教学环节质量的考核、评价还停留在原来的评价手段和方法上。本文是立足高职高专教育的人才培养目标 ,构建高职高专实践教学环节的质量评价的新平台。通过质量评价体系评价 ,客观、公正、科学、合理的评价学生的实践技能 ,同时改变那些不符合要求的实践技能培养模式

学年体育教学计划季候性特点与周期划分的研究

采用实验研究的方法，对两年来按体育课学年教学计划季候性特点与周期划分实施教学的实验班与按普通计划完成相同内容实施教学的对照班进行比较分析。结果表明：实验班的人体素质和运动技术、技能明显好于对照班。这对明确科学划分学年体育教学计划的意义和各周期的任务提供了有力的证据。使制订学年体育教学计划向着更有时间性、季节性、气候性和针对性，更切合外界客观规律和环境条件，更符合学生的生理和心理特点，以便取得更好的教学效果方向发展奠定了理论与实践基础。

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.

谢灵运《拟魏太子邺中集诗八首》中的邺下之游

谢灵运的《拟邺中》以建安时代邺下诗人为模拟对象,成功地模拟了曹丕记忆中“欢愉之极”的生活。但是,在拟诗中的诸子放弃了各自的理想,安于享乐生活,且忽略了曹氏父子与邺下文士之间的矛盾和摩擦,这并不完全符合史实。邺下之游是存在于曹丕脑海中的完美记忆,而谢灵运却将它扩大为一个时代一个精英群体的集体性完美记忆。
