Analysis of Statistical Question Classification for Fact-Based Questions   总被引：1，自引：0，他引：1  

Donald Metzler  W. Bruce Croft 《Information Retrieval》2005,8(3):481-504

Question classification systems play an important role in question answering systems and can be used in a wide range of other domains. The goal of question classification is to accurately assign labels to questions based on expected answer type. Most approaches in the past have relied on matching questions against hand-crafted rules. However, rules require laborious effort to create and often suffer from being too specific. Statistical question classification methods overcome these issues by employing machine learning techniques. We empirically show that a statistical approach is robust and achieves good performance on three diverse data sets with little or no hand tuning. Furthermore, we examine the role different syntactic and semantic features have on performance. We find that semantic features tend to increase performance more than purely syntactic features. Finally, we analyze common causes of misclassification error and provide insight into ways they may be overcome.  相似文献

外来术语的引进与学术本土化——以softpower的汉语翻译之争为例     

古俊伟 《太原大学学报》2011,12(3):64-68

外来术语的引进不仅仅是一个简单的翻译问题。softpower这一术语进入中国之后被翻译为“软实力”、“软权力”和“软力量”，甚至引起了学者间的持久争论。从术语学的角度看，对softpower的翻译违反了术语的单义性和单名性原则，没有充分考虑来源语中该术语的概念体系和目标语中该术语的概念体系，以及这两个概念体系之间的对应。从翻译学的角度看，解构主义给翻译的异化原则提供了理论支持，使译者对来源语术语的忠诚度减弱，自我创作成分增加。从意识形态的视角看，学术本土化为通过术语翻译的方式进行所谓的创新提供了道义支持。  相似文献

Managing What We Can Measure: Quantifying the Susceptibility of Automated Scoring Systems to Gaming Behavior     

Derrick Higgins  Michael Heilman 《Educational Measurement》2014,33(3):36-46

As methods for automated scoring of constructed‐response items become more widely adopted in state assessments, and are used in more consequential operational configurations, it is critical that their susceptibility to gaming behavior be investigated and managed. This article provides a review of research relevant to how construct‐irrelevant response behavior may affect automated constructed‐response scoring, and aims to address a gap in that literature: the need to assess the degree of risk before operational launch. A general framework is proposed for evaluating susceptibility to gaming, and an initial empirical demonstration is presented using the open‐source short‐answer scoring engines from the Automated Student Assessment Prize (ASAP) Challenge.  相似文献   

选择适应论视野下翻译中的图式移植     

魏薇 《湖南第一师范学报》2012,(6):98-101

翻译的过程在某种程度上可理解为“图式移植”的过程，移植内容、移植方式贯穿译者的整个创作过程。图式移植的实现是译者主动选择和适应的结果，移植成功与否与译者做出的选择和适应息息相关。  相似文献
