46种中华医学会系列杂志的审稿与退修程序分析

为了解委托办中华医学会系列杂志在审稿方面存在的问题,探讨改进措施,以规范审稿制度与规则,抽检46种期刊的46期,发现不少共同性的问题.建议:参加终审定稿会的人数不得少于5人,要有记录,要有签字;退修并不是次数越多越好,编辑要尽可能地将专家审稿意见、编委会的终审意见消化吸收,加上自己的意见一次性转告作者,以便作者通盘考虑,全面修改.     

论中国古代藏书楼的文化意义

藏书楼是藏书活动的建筑载体,是我国传统文化的重要标志之一。中国古代藏书楼在其命名、建筑设计、空间布局和环境建设等方面独具特征,而这些特征的产生既有主观原因,也有客观原因。藏书楼对我国传统文化的传承和保护起到了重要作用,应该对现存藏书楼加以大力保护。     

Retrieving and classifying instances of source code plagiarism

Automatic detection of source code plagiarism is an important research field for both the commercial software industry and within the research community. Existing methods of plagiarism detection primarily involve exhaustive pairwise document comparison, which does not scale well for large software collections. To achieve scalability, we approach the problem from an information retrieval (IR) perspective. We retrieve a ranked list of candidate documents in response to a pseudo-query representation constructed from each source code document in the collection. The challenge in source code document retrieval is that the standard bag-of-words (BoW) representation model for such documents is likely to result in many false positives being retrieved, because of the use of identical programming language specific constructs and keywords. To address this problem, we make use of an abstract syntax tree (AST) representation of the source code documents. While the IR approach is efficient, it is essentially unsupervised in nature. To further improve its effectiveness, we apply a supervised classifier (pre-trained with features extracted from sample plagiarized source code pairs) on the top ranked retrieved documents. We report experiments on the SOCO-2014 dataset comprising 12K Java source files with almost 1M lines of code. Our experiments confirm that the AST based approach produces significantly better retrieval effectiveness than a standard BoW representation, i.e., the AST based approach is able to identify a higher number of plagiarized source code documents at top ranks in response to a query source code document. The supervised classifier, trained on features extracted from sample plagiarized source code pairs, is shown to effectively filter and thus further improve the ranked list of retrieved candidate plagiarized documents.

Diversity in the Information Seeking Behaviour of the Virtual Scholar: Institutional Comparisons

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions.
