Two-stage statistical language models for text database selection

As the number and diversity of distributed Web databases on the Internet exponentially increase, it is difficult for user to know which databases are appropriate to search. Given database language models that describe the content of each database, database selection services can provide assistance in locating databases relevant to the information needs of users. In this paper, we propose a database selection approach based on statistical language modeling. The basic idea behind the approach is that, for databases that are categorized into a topic hierarchy, individual language models are estimated at different search stages, and then the databases are ranked by the similarity to the query according to the estimated language model. Two-stage smoothed language models are presented to circumvent inaccuracy due to word sparseness. Experimental results demonstrate that such a language modeling approach is competitive with current state-of-the-art database selection approaches.     

早期记者的职业意识和精神危机

早期记者产生于外人所办报馆 ,孕育于半殖民地半封建社会。从产生之初就深受西方新闻观念影响。中国最早的现代意义上的记者正是在西方文化冲击下 ,初步形成了自己的职业意识和观念。同时 ,他们又受传统文化影响 ,难以摆脱传统观念影响 ,热衷科举 ,对西方文化表现出排斥心理。本文试图通过揭示早期记者的职业认同危机、科举情结、文化认同危机 ,考察分析早期记者的职业意识和精神状况 ,以及其对新闻工作的影响     

教学的价值自觉

教师不是任何教学价值的附属物,不是既定教学价值的分享者和发现者,而应是教学价值的创造者和实现者。当前,教学的价值自发主要表现为教学的价值游移、价值错位和价值虚无。多元教学价值的时代,教师需要明确教学的价值立场、增强教学价值的自信、积极推动教学的价值创造,从而铸造自己的人格,形成自由的个性,将教学提升到崇高的道德水准上,展现教师应有的德性之光。     

扩展的VSM图书馆读者兴趣建模技术研究

认为读者兴趣建模是实现图书馆主动信息服务技术的关键,传统的VSM向量模型不能很好地从读者的图书访问行为记录中提取更多的信息用于建立用户兴趣模型。提出一种新的读者兴趣建模技术,对传统VSM模型加以扩展,从读者的静态特征信息和不同的访问行为信息中构建两层结构的兴趣模型,可以更精确地发现和描述读者的阅读偏好,提高主动信息推送的准确性。
     

Analysis and conservation of modern modeling materials found in Auguste Rodin's sculptures

Prior to the exhibition Portrait-making, Rodin and his models (2009), the Rodin museum wanted to restore two busts of Hanako and Clemenceau. Interestingly, these two sculptures contain pieces of modern modeling materials (MMMs) invented at the end of the nineteenth century as an alternative to clay or waxes. The poor state of conservation of the two portraits made any handling and exhibition impossible. Accordingly, the purpose of this article is twofold: to contribute to technical art history and conservation. Elemental and chemical analyses were done on samples from 12 sculptures (SEM–EDX, FTIR, GC–MS, GC–FID, XRD, synchrotron-based µXRF, µXANES, and µFTIR) aimed at identifying the composition of MMMs used by Rodin on plaster sculptures and establishing hypotheses about the origins of their degradation. This thorough study of their composition and degradation was necessary to implement an appropriate restoration plan. The development of conservation protocols adapted to such materials is rarely documented. Different tests were performed on mock-ups (pH, solubility, adhesion, consolidation, and cleaning). In particular, a protocol based on laser cleaning was developed and successfully applied to remove superficial dust and crusts so that the sculptures regained their original aspect.     

中美贸易战社交媒体话语的情感倾向及主题焦点研究

为了探究西方社交媒体对中美贸易战的态度及关注焦点,本文爬取了贸易战期间Twitter上相关的热门英文推文,对其进行了情感倾向分析和主题建模。研究发现83%的推文带有消极情感倾向且情绪反应激烈;对消极推文的主题建模展示了Twitter用户对贸易战的八大评论焦点,几乎全部围绕贸易战给美国及世界带来的诸多不利影响。研究结果表明特朗普在贸易战这一经济策略上受到了普遍的批评和抨击,并没有得到民意的支持。
