长距离疑问句/填充词-缺位构式的汉-英中介语终端状态研究     

马志刚 《外语教学理论与实践》2012,1(2):36

生成语法认为,英语长距离疑问句的生成要依赖疑问词的连续循环移位,而构式语法则认为,信息地位兼容的构式相互组合就生成长距离疑问句。现有二语研究文献表明,疑问词所在的句法位置(句式变体)和从句的信息地位,都可能影响英语长距离疑问句的二语习得状况。基于生成二语观和构式二语观,本研究首先对长距离疑问句的六种变体句的二语习得状况作出预测,然后以规范的实证调查方式加以验证。本研究发现,在中介语终端状态中,句式变体和信息地位之间的交互作用是影响长距离疑问句是否合法的主要因素,而现有研究大多只关注其中的一个因素,因此得出的结论都过于片面。  相似文献

On the role of user-centred evaluation in the advancement of interactive information retrieval   总被引：1，自引：0，他引：1  

Daniela Petrelli 《Information processing & management》2008

This paper discusses the role of user-centred evaluations as an essential method for researching interactive information retrieval. It draws mainly on the work carried out during the Clarity Project where different user-centred evaluations were run during the lifecycle of a cross-language information retrieval system. The iterative testing was not only instrumental to the development of a usable system, but it enhanced our knowledge of the potential, impact, and actual use of cross-language information retrieval technology. Indeed the role of the user evaluation was dual: by testing a specific prototype it was possible to gain a micro-view and assess the effectiveness of each component of the complex system; by cumulating the result of all the evaluations (in total 43 people were involved) it was possible to build a macro-view of how cross-language retrieval would impact on users and their tasks. By showing the richness of results that can be acquired, this paper aims at stimulating researchers into considering user-centred evaluations as a flexible, adaptable and comprehensive technique for investigating non-traditional information access systems.  相似文献   

Exploring usefulness and usability in the evaluation of open access digital libraries     

Giannis Tsakonas  Christos Papatheodorou 《Information processing & management》2008

Advances in the publishing world have emerged new models of digital library development. Open access publishing modes are expanding their presence and realize the digital library idea in various means. While user-centered evaluation of digital libraries has drawn considerable attention during the last years, these systems are currently viewed from the publishing, economic and scientometric perspectives. The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive. The results demonstrate that several attributes of usefulness, such as the level and the relevance of information, and usability, such as easiness of use and learnability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction.  相似文献
