维基百科词条编辑特性研究

针对维基百科词条编辑特性问题,以网络化数据挖掘思想方法为指导,对高质量维基百科词条进行文本分析,判断词条相邻版本间句子差异,以编辑者为节点,编辑者间编辑交互关系为连边,构建词条编辑交互网络,通过分析网络结构特征实现词条编辑特性分析。分析表明网络具有小世界特性,度分布与强度分布相似,具有较强正相关性,其累积分布与边权重分布服从幂律分布,节点度与聚集系数具有较强负相关性,最短路径长度分布与高斯分布相似,网络具有异配性和较弱的互惠性,编辑群体具有较强异质性、抱团性;深化了对词条编辑交互过程和群体智能的认识。

Software engineering article types: An analysis of the literature

The software engineering (SE) community has recently recognized that the field lacks well-established research paradigms and clear guidance on how to write good research reports. With no comprehensive guide to the different article types in the field, article writing and reviewing heavily depends on the expertise and the understanding of the individual SE actors.In this work, we classify and describe the article types published in SE with an emphasis on what is required for publication in journals and conference proceedings. Theoretically, we consider article types as genres, because we assume that each type of article has a specific function and a particular communicative purpose within the community, which the members of the community can recognize. We draw on written sources available, i.e. the instructions to authors/reviewers of major SE journals, the calls for papers of major SE conferences, and previous research published on the topic.Despite the fragmentation and limitations of the sources studied, we are able to propose a classification of different SE article types. Such classification helps in guiding the reader through the SE literature, and in making the researcher reflect on directions for improvements.

Effect of Sr and Ce on Synthesis of Nanometer Perovskite LaMnO3＋λ

Nanometer perovskite LaMnO3 λ, La0.6Ce0.4MnO3 λ and La0.6Sr0.4MnO3 λ were prepared by citric acid-aide dsol-gel method. The effects of Ce, Sr on the structure and properties of nanometer perovskite were studied through DTTGA, XRD, TEM and BET analyses. The results show that, by sol-gel method, LaMnO3 λ, La0.6Ce0.4MnO3 λ and La0.6Sr0.4MnO3 λ were made with average particle size of about 60, 100 and 30 nm, respectively. After partially substituting Sr on La positions in LaMnO3 λ, it is found that Sr is located at the perovskite lattice so as to reduce the formation temperature of the perovskite. As a result, the perovskite has a smaller particle size and larger specific surface area. On the contrary, it is difficult for Ce to enter the perovskite lattice. Ce exists mostly in the form of CeO2 as partially substituting La in LaMnO3 λ. The formation temperature of the perovskite increases, and the catalyst containing CeO2 presents a larger particle size and less specific surface area.
