Construction of query concepts based on feature clustering of documents

In Information Retrieval, since it is hard to identify users’ information needs, many approaches have been tried to solve this problem by expanding initial queries and reweighting the terms in the expanded queries using users’ relevance judgments. Although relevance feedback is most effective when relevance information about retrieved documents is provided by users, it is not always available. Another solution is to use correlated terms for query expansion. The main problem with this approach is how to construct the term-term correlations that can be used effectively to improve retrieval performance. In this study, we try to construct query concepts that denote users’ information needs from a document space, rather than to reformulate initial queries using the term correlations and/or users’ relevance feedback. To form query concepts, we extract features from each document, and then cluster the features into primitive concepts that are then used to form query concepts. Experiments are performed on the Associated Press (AP) dataset taken from the TREC collection. The experimental evaluation shows that our proposed framework called QCM (Query Concept Method) outperforms baseline probabilistic retrieval model on TREC retrieval.     

Google应用技巧

文章详细分析了网络搜索引擎Google 的功能特征, 讨论了在使用中存在的一些现象和问题。通过具体例证说明: 在进行组合查询时, 要对所有的查询词分别加引号; Google 在对中文繁简字体语义转换时, 有可能出现明显的错误; 搜索到的数据在同一范围内、在以小时为单位内也会出现巨大的变化; 以及在不同范围内, 搜索同一信息时, 随时间的不同, 搜索到的结果会有不同的排序。

基于信息融合的档案知识服务研究

基于信息融合的档案知识服务,是借助信息融合的理念和技术,对档案信息资源、用户需求信息等进行综合处理与协同利用,推动档案信息资源在数据层面的关联和知识层面的重构,实现面向用户需求的档案知识发现和知识服务的过程.论文构建了由一个目标、两种资源、三个模块、四个环节构成的基于信息融合的档案知识服务框架,并从多源信息获取、信息综合处理、信息融合和档案知识服务方面,探讨了基于信息融合的档案知识服务实现流程.     

The powerful image and the imagination of power: the ‘new visual turn’ of the CPC’s propaganda strategy since its 18th National Congress in 2012

This paper adopts the academic tool of discourse analysis to examine the ‘new visual turn’ of the Communist Party of China’s propaganda work since the 18th CPC National Congress when Xi Jinping was inaugurated as the leader of Chinese Communists. A thorough review of the new visual means the Party uses for photojournalism, TV news, animated cartoons and online promotional videos points to three developments markedly different from traditional discursive strategies: a full embrace of Confucian ethics, articulation of the Internet-based popular culture and subcultures, and an effort to fortify Xi’s personal authority as a political idol. The paper concludes that the ‘new visual turn’ of CPC propaganda after the 18th Party Congress suggests that the Communist discourse has evolved to a new stage where sophisticated manipulation of sleek technological tools substantiates a rigorous, dynamic CPC discursive system more at ease with itself and more powerful than ever in shaping the mainstream political culture in China.

生存分析法在学术期刊评价上的应用初探

期刊评价中文献老化理论视角的研究相对薄弱。本文探究生存分析法在学术期刊评价上的应用,在理论上 克服了因领域差异导致的壁垒,并选取CSTPCD中30家中文物理学科期刊作为样本数据集进行实证研究。通过对论文 被引时序数据进行分析,研究物理学科文献老化规律,并选取样本期刊进行对比分析,以探究期刊评价的新思路。     

中日印韩四国2011—2015年国际顶级期刊论文产出状况及国际地位对比分析

为了研究科研成果高水平论文产出状况,了解中日印韩四国近五年在国际顶级期刊(Cell、Nature、Science,CNS)论文产出以及国际地位变化,利用Web of Science统计2011—2015年中日印韩在CNS论文产出情况和国际地位变化.研究发现:我国与日本并驾齐驱,并大有赶超日本的趋势,二者约占四国论文总数的80％;印度和韩国仅占20％.国际排名则中日较为靠前,期间中国增长最为迅速,印度和韩国保持相对稳定,日本增长最低.我国2011—2015年CNS论文产出增长势头明显,相关系数呈正相关,并在2015年全面超越日本并进一步拉开差距,在四国当中首屈一指,但以后可能进入一种新常态模式,为此提出两点建议期望能保持高质量论文中高速增长.
