Intent-based diversification of web search results: metrics and algorithms

We study the problem of web search result diversification in the case where intent based relevance scores are available. A diversified search result will hopefully satisfy the information need of user-L.s who may have different intents. In this context, we first analyze the properties of an intent-based metric, ERR-IA, to measure relevance and diversity altogether. We argue that this is a better metric than some previously proposed intent aware metrics and show that it has a better correlation with abandonment rate. We then propose an algorithm to rerank web search results based on optimizing an objective function corresponding to this metric and evaluate it on shopping related queries.

现代教育技术与大学英语教学质量评估

大学英语是实践性强的学科,其核心目的是培养较好的语言运用能力。大学英语学科性质决定了教学模式应该突出学生自主学习与合作学习,而不是知识讲授。自主学习的教学模式决定了充分运用现代教育技术的必要性。现行教师教学质量评价体系比较粗糙,没有依据学科特点进行细化。大学英语教学质量评估应该从知识讲授型学科的教学质量评估体系中独立出来,把现代教育技术的合理和充分运用作为重要评价指标。

基于WLAN的图书馆读者行为采集分析平台框架研究

[目的/意义]读者行为分析是图书馆改进服务、提升管理水平的基础性工作。目前在馆读者越来越多地通过馆内WLAN来访问图书馆资源和服务,因此对这部分读者的行为进行分析变得越来越重要。而当前图书馆界十分缺乏对馆内通过WLAN上网读者的行为进行采集分析的工具和手段。[方法/过程]设计一种基于WLAN网络的图书馆读者行为采集分析平台框架,并提出平台各关键技术点及其解决方案。[结果/结论]该平台框架及技术解决方案可为相关平台系统的开发和使用提供参考,但是在隐私保护和安全性方面还需要在应用中进一步调整和优化。     

鲁迅小说中女性形象的悲剧审美价值

在鲁迅小说的整个审美世界中,女性形象占有一席特殊的显赫的位置。鲁迅以其独特的悲剧意识和忧患意识,揭示了旧中国妇女既是社会悲剧又是性格悲剧的全部内涵,鲁迅侧重挖掘她们性格的缺陷软弱和致使自己失败的内在因素,体现了鲁迅对历史的悲剧思考。     

朱熹《中庸章句》及其儒学思想

《中庸章句》以性——气二元论为基点,以道心、人心对应于性命、形气,但同时突出性即理,强调人之性受之于天之理,人性即是天命之性。由于人的气禀使得人之本性的表现受到气的影响和遮蔽,所以人不能自然而无所修为,必须修道立教,以戒慎恐惧和慎独的功夫,在未发和已发的时候都用力修养,强力人为。通过明善致知和诚身存心两方面同时努力,以全其性之本体,渐入于中和圣域。在这种解释中,天命之性是起点,但最后落实在修道之教的功夫,而修道功夫需诚明两进,不能偏废。在《中庸章句》中,理学的理气论、天理论、心性论、功夫论都得到了全面的贯彻,成功地借助对于经典的系统解释展示了新儒学的理论建构,对理学思想的传播起了关键性的作用。     

《萧山戚氏家谱》序

家谱为表谱之一种，记载以血缘关系为主体之家族世系与族人事迹之编纂体裁。肇端于远古，甲骨、金文已见其雏形；商周以还，官私撰述，为数不少。太史公撰《史记》即参考春秋之前大量谱牒，故其《自序》云：“维三代尚矣，年纪不可靠，盖取之谱牒旧闻”，惜多已亡佚难求。     

Meaning of life as a protective factor of positive affect in acculturation: A resilience framework and a cross-cultural comparison

Although research has demonstrated a strong linkage between meaning of life and positive emotion, few studies have examined this association in the context of acculturation. The purpose of this study was to investigate the predictive effects of meaning of life and acculturative stressor on positive affect in a sample of Chinese international students in Australia and Hong Kong, and to compare these effects between the two groups. Four hundred mainland Chinese postgraduate students at six universities in Hong Kong and 227 Chinese international students at the University of Melbourne in Australia completed a questionnaire that included measures of acculturative stressor, meaning of life, positive affect, and demographic information. The analyses revealed that (1) meaning of life had a strong positive contribution to predict positive affect in acculturation, and acculturative stress had a negative impact on positive affect within both samples; (2) social interaction had a significant negative predictive effect on positive affect in both samples, and academic work served as a significant negative predictor of positive affect in the Hong Kong sample; and (3) meaning of life was found to mediate the relationship between acculturative stress and positive affect in both samples. The theoretical and practical implications of the study are discussed.
