一种基于图划分的无监督汉语指代消解算法

指代消解是自然语言处理领域中的一个重要问题。针对当前中文指代标注训练语料非常缺乏的现状,本文提出一种无监督聚类算法实现对名词短语的指代消解。引入图对名词短语的指代消解问题进行建模,将指代消解问题转化为图划分问题,并引入一个有效的模块函数实现对图的自动划分,使得指代消解过程并不是孤立地对每一对名词短语分别进行共指决策,而是充分考虑了多个待消解项之间的相关性,并且避免了阈值选择问题。通过在ACE中文语料上的人称代词消解和名词短语消解实验结果表明,该算法是一种有效可行的无监督指代消解算法。     

面向大规模定制的外圆磨床定制设计

随着市场全球化的发展和竞争程度的不断加剧，原有的大批量生产模式逐渐被大规模定制模式所代替，面向大规模定制的产品族设计成为研究的重点，本文对基于Internet面向大规模定制模式下的外圆磨床设计方法进行了探讨，其实现过程主要包括两步：产品族模型的建立和产品实例的生成，并对该网络系统的实现进行了理论研究。

为了提高产品的设计效率和自主创新开发能力,在剖析了卧式螺旋卸料沉降离心机的主要结构和工作原理基础上,提出了基于混合推理的模块化产品变型设计技术。将基于规则推理和基于实例推理技术集成于混合推理机制并应用到产品的整个开发周期中,采用模块化技术将卧螺离心机产品层级模块化,整合设计领域的专家经验和专业知识集成于一套完备、智能的专家系统,开发了卧螺离心机产品变型设计系统。最后,应用实例验证了系统的规范化和智能化。     

Why cognitive science is not formalized folk psychology

It is often assumed that cognitive science is built upon folk psychology, and that challenges to folk psychology are therefore challenges to cognitive science itself. We argue that, in practice, cognitive science and folk psychology treat entirely non-overlapping domains: cognitive science considers aspects of mental life which do not depend on general knowledge, whereas folk psychology considers aspects of mental life which do depend on general knowledge. We back up our argument on theoretical grounds, and also illustrate the separation between cognitive scientific and folk psychological phenomena in a number of cognitive domains. We consider the methodological and theoretical significance of our arguments for cognitive science research.     

Of Hackers and Hairdressers: Modularity and the Organizational Economics of Open-source Collaboration

Using the idea of modularity, we study the general phenomenon of open-source collaboration, which includes such things as collective invention and open science in addition to open-source software production. We argue that open-source collaboration coordinates the division of labor through the exchange of effort rather than of products: suppliers of effort self-identify in the same way as suppliers of products in a market rather than accepting assignments like employees in a firm. We suggest that open-source software (and other) projects are neither bazaars nor cathedrals, but hybrids manifesting both voluntary production and conscious planning.
