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

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
