A citation-based document retrieval system for finding research expertise

Current citation-based document retrieval systems generally offer only limited search facilities, such as author search. In order to facilitate more advanced search functions, we have developed a significantly improved system that employs two novel techniques: Context-based Cluster Analysis (CCA) and Context-based Ontology Generation frAmework (COGA). CCA aims to extract relevant information from clusters originally obtained from disparate clustering methods by building relationships between them. The built relationships are then represented as formal context using the Formal Concept Analysis (FCA) technique. COGA aims to generate ontology from clusters relationship built by CCA. By combining these two techniques, we are able to perform ontology learning from a citation database using clustering results. We have implemented the improved system and have demonstrated its use for finding research domain expertise. We have also conducted performance evaluation on the system and the results are encouraging.

民间智库在创新驱动战略中的重要作用

中国自古以来就有幕僚传统,但现代意义上民间智库则是改革开放以后逐渐发展起来的。进入21世纪,随着国际局势和国内经济社会发展形势的重大变化,国家明确提出实施创新驱动发展战略,民间智库进入蓬勃发展的新阶段。作为创新驱动的强大助推力量,民间智库既是中国新经济发展的强大动力、也是国家治理体系和治理能力现代化的重要支撑,应进一步完善我国民间智库发展的政策环境,按照研究能力标准而非体制标准评价民间智库,促进民间智库更好服务于创新驱动国家战略。     

Design of a fast real-time LPV model predictive control system for semi-active suspension control of a full vehicle

This article is concerned with the control of a Semi-Active suspension system of a 7DOF Full Vehicle model, equipped with four Electro Rheological (ER) dampers, taking into account their incipient dissipativity constraints. Herein, a real-time, fast, advanced control structure is presented within the Model Predictive Control framework for Linear Parameter Varying (LPV) systems. The control algorithm is developed to provide a suitable trade-off between comfort and handling performances of the vehicle in a very limited sampling period ($T_s=5\text{ms}$), in view of a possible realtime implementation on a real vehicle. The control structure is tested and compared to other standard fast control approaches. Full nonlinear realistic simulation results illustrate the overall good operation and behaviour of the proposed control approach.     

关于莫高窟第217窟南壁壁画的思考

莫高窟第217窟南壁的壁画,以前考证为法华经变,近年日本学者下野玲子以《佛顶尊胜陀罗尼经》来比对这幅壁画,推翻了以前的法华经变的结论。但下野的考证仍存在很多问题,本文在检讨了诸多问题之后,认为这铺壁画既不是法华经变,也非佛顶尊胜陀罗尼经变,壁画的主题仍须进一步探讨。     

从社会语言学角度解析委婉语的成因

随着社会经济的不断发展,人们已不再满足于追逐一定的物质文化,精神文化成了大家孜孜以求的方向和目标。语言作为人们日常交流的工具是精神交流的重要媒介。语言交流中有些需要避讳的地方,我们就必须巧妙地借助于委婉语去交流。本文首先简介委婉语的概况,其次举例常见委婉语实例,最后引出本文论点。从社会语言学的三个角度解析委婉语的成因:社会成因,文化成因和地区成因。目的是帮助人们更好地了解委婉语的来由,更好地使用委婉语以促进日常交流的顺畅和谐。
