Automatic ranking of information retrieval systems using data fusion     

Rabia Nuray  Fazli Can 《Information processing & management》2006

Measuring effectiveness of information retrieval (IR) systems is essential for research and development and for monitoring search quality in dynamic environments. In this study, we employ new methods for automatic ranking of retrieval systems. In these methods, we merge the retrieval results of multiple systems using various data fusion algorithms, use the top-ranked documents in the merged result as the “(pseudo) relevant documents,” and employ these documents to evaluate and rank the systems. Experiments using Text REtrieval Conference (TREC) data provide statistically significant strong correlations with human-based assessments of the same systems. We hypothesize that the selection of systems that would return documents different from the majority could eliminate the ordinary systems from data fusion and provide better discrimination among the documents and systems. This could improve the effectiveness of automatic ranking. Based on this intuition, we introduce a new method for the selection of systems to be used for data fusion. For this purpose, we use the bias concept that measures the deviation of a system from the norm or majority and employ the systems with higher bias in the data fusion process. This approach provides even higher correlations with the human-based results. We demonstrate that our approach outperforms the previously proposed automatic ranking methods.  相似文献   

Cross-Sectoral Differences in Intellectual Property Enforcement in Developing Countries: The Role of State-Industry Linkages     

Krishna P. Jayakar 《The Information Society》2003,19(2):155-169

Leading developing countries have recently introduced some reforms in their national intellectual property regimes to harmonize them with international treaties and agreements. However, major differences remain in how these laws are applied to different information industries, and how they are enforced on the ground. While intellectual property law applies to a host of information products ranging from music to computer programs, governments have selectively enforced the law in some information industries, while neglecting to extend the same protection to others. Based on the comparative institutionalist approach, this article identifies two variables--state-industry linkages and level of innovative activity--that may explain the selective enforcement of intellectual property law. Intellectual property rights were expected to be better protected in information industries with strong state-industry linkages and higher levels of domestic innovation. This expectation was tested through a comparative study of four intellectual property industries from the Asian region. The results confirmed the expectation, but also demonstrated that strong state-industry linkages may independently correlate with high levels of intellectual property protection, even in industries where the current levels of innovative activity are low.  相似文献

1　开放封装的意义现实系统环境是一个由众多分布、异构和自主的资源系统组成的开放环境 ,现实应用则要求对这些系统进行整合来向用户提供逻辑化甚至个性化的集成服务。为了形成有效的集成服务 ,我们可以要求新建设的资源系统采用标准的元数据格式、检索方式、检索记录调用机制、检索记录传输格式和传输协议 ,从而支持整合检索、开放链接和基于Web的集成使用[1] 。但对于已经存在的资源系统和第三方资源系统 (在中国科学院这些系统可能占多数 ) ,它们往往各自具有自己的数据结构、检索方式、检索与调用协议、数据记录传输格式等。我们不可…  相似文献

全球知识搜索与企业创新：东道国选择之困          下载免费PDF全文

唐宜红  俞峰  王晓燕 《科研管理》2019,40(4):213-223

本文将2008-2011年中国科技部企业创新数据库、世界银行全球治理数据库和Hofstede关于文化的研究数据合并，基于东道国视角，研究东道国正式制度和文化制度对全球知识搜索与创新绩效关系的调节作用。实证结果表明外部知识搜索促进了企业创新绩效，前人提出的倒U型关系曲线的“拐点”尚未出现。进一步结合东道国制度因素对其探讨，发现东道国正式制度中的法律规则与监管质量负向调节搜索行为与创新绩效的关系；而文化制度中的长期导向正向调节二者之间的关系，权力距离的负向调节作用未出现。此外，我们还发现在上述东道国制度调节下全球知识搜索所实现的中国企业创新，仍以渐进式创新为主，颠覆式创新则略显乏力。  相似文献

E-Commerce to Protect the Network Relationships: The Case of Taiwan's PC Industry     

Tain-Jy Chen 《The Information Society》2003,19(1):59-67

Although Taiwan is one of the world's leading producers of information products, it lags behind advanced countries in the application of information technologies. The strength of Taiwan's industry lies in its low-cost manufacturing capabilities, which in recent years have been undermined by rising wages. Faced with a massive relocation of production activities to China, the Taiwanese government is trying to prevent the hollowing out of domestic industry by encouraging local firms to embrace new information technologies to strengthen their ties to multinational firms. The initiative aims at enhancing the flexibility of production and speeding up responses to the market through concerted actions by brand marketers, parts suppliers, and assemblers. New technologies underscore new working methods that erect entry barriers to protect existing network relationships.  相似文献
