Objective: To describe the revolution and research status of Advances in Psychological Science. Methods: A total of 3060 articles published in Advances in Psychological Science from 1983 to 2014 were analyzed with the information visualization method using Citespace software from the aspects of pub- lications, cited frequency and downloads, funding, organizations, authors and keywords. Results: The results showed that the amount of literature published annually had an upward tendency, and 49.4% of the papers were supported by national or provincial projects. Institutions such as the Chinese Academy of Sciences (CAS) and the normal universities were rated in the forefront of the sci- entific research output. Xiting Huang, Hong Li and Yuejia Luo were at the top of the list of prolific authors. Conclusions: A new pattern of cooperative development of the theory and application in the field of psychological research is forming. 展开更多

The middle reaches of the Yangtze River were the key areas of central China emphasized in many strategic plans.It was also an important ecological and fragile area,because there are many wetlands,lakes,rivers and soil erosion area.And it linked the ecological fragile upper reaches of the Yangtze River with the most developed Yangtze River Delta in China.It is urgent to figure out the key industries,key areas and key ecological and environmental problems for the strategic environmental assessment of the middle reaches of the Yangtze River.The important regions consisted of the economic key region,the planning key region,the ecological key region,and the fragile ecological region.The key industries consisted of the ones contributed to economic growth,or affecting the environment,or preferred by the local government.Besides,the ecological and environmental problems involved the water environment,the atmosphere environment,and the ecological environment.The key regions were identified through word frequency statistics of many plans by ROST Word Parser.And it was spatially overlaid by ArcGIS9.2.The key industries were calculated based on the economic statistics data,the environmental pollution census and the word frequency statistics.Based on SCI-EXPANDED,CPCI-S,CCR-EXPANDED,IC database and Chinese CNKI periodical database,the ecological and environmental problems of the middle reaches of the Yangtze River were analyzed by Citespace software according to the keywords and abstract of every paper.The results show that the important regions of the middle reaches of the Yangtze River concentrated in the central urban region,along the river and lake,surrounding mountains,and the wetland.The equipment manufacturing,chemical industry,mining industry,energy supply industry,food industry,textile and garment industry were the key industries need to be focused on.The urgent ecological and environmental problems in the middle reaches of the Yangtze River were the water environment pollution,water ecosystem,heavy metal pollution,soil and wetlands destruction,organic pollution and biodiversity decrease issues.. 展开更多

Long-document semantic measurement has great significance in many applications such as semantic searchs, plagiarism detection, and automatic technical surveys. However, research efforts have mainly focused on the semantic similarity of short texts. Document-level semantic measurement remains an open issue due to problems such as the omission of background knowledge and topic transition. In this paper, we propose a novel semantic matching method for long documents in the academic domain. To accurately represent the general meaning of an academic article, we construct a semantic profile in which key semantic elements such as the research purpose, methodology, and domain are included and enriched. As such, we can obtain the overall semantic similarity of two papers by computing the distance between their profiles. The distances between the concepts of two different semantic profiles are measured by word vectors. To improve the semantic representation quality of word vectors, we propose a joint word-embedding model for incorporating a domain-specific semantic relation constraint into the traditional context constraint. Our experimental results demonstrate that, in the measurement of document semantic similarity, our approach achieves substantial improvement over state-of-the-art methods, and our joint word-embedding model produces significantly better word representations than traditional word-embedding models. 展开更多
