Effective top-k computation with term-proximity support

Modern web search engines are expected to return the top-k results efficiently. Although many dynamic index pruning strategies have been proposed for efficient top-k computation, most of them are prone to ignoring some especially important factors in ranking functions, such as term-proximity (the distance relationship between query terms in a document). In our recent work [Zhu, M., Shi, S., Li, M., & Wen, J. (2007). Effective top-k computation in retrieving structured documents with term-proximity support. In Proceedings of 16th CIKM conference (pp. 771–780)], we demonstrated that, when term-proximity is incorporated into ranking functions, most existing index structures and top-k strategies become quite inefficient. To solve this problem, we built the inverted index based on web page structure and proposed the query processing strategies accordingly. The experimental results indicate that the proposed index structures and query processing strategies significantly improve the top-k efficiency. In this paper, we study the possibility of adopting additional techniques to further improve top-k computation efficiency. We propose a Proximity-Probe Heuristic to make our top-k algorithms more efficient. We also test the efficiency of our approaches on various settings (linear or non-linear ranking functions, exact or approximate top-k processing, etc.).

朱自清、朱光潜的写作理论

在现代写作理论史上，朱自清，朱光潜的研究成果是很有价值的理论遗产。“二朱”身为名作家，学，兼具中西学术，语的深厚修养，在写作理论方面的建树更具视野开阔，见解深刻的特色，当前写作理论应认真研究，从中汲取营养。     

试论现代写作学理论范畴的逻辑系统

现代写作学的理论建构只能走自我创建之路。现代写作学的范畴研究 ,从“老八块”到“新八论” ,朝着动与静、人与文、知与行、宏与微四结合的方向发展 ,形成了由“写作现象”、“写作行为”、“写作内核”三大系列构成的逻辑系统 ,显示出由表及里的包容性和由里而外的生发性     

师专写作教改新探索

从师专学生自身的特点出发,从激发学生写作兴趣、营造开放的教学环境、重视写作练习设计、重视培养学生自己改的能力四个方面来改革教学方法,以达到提高学生写作能力的目的。     

大学写作教学改革初探

自上世纪80年代末以来余国瑞主持完成了两项大学写作教学改革课题。在更新教学内容方面，初步建立起以系统科学为指导，具有更大包容性的新的写作理论框架；在改革教学方法方面，以转变教学观念为先导，采用新的教学和考核办法。试验证明，新的写作理论和教学方法虽然还存在不少问题，但效果是好的，方向是正确的。

The effect of use and access on citations

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect.
