企业技术核心能力的AHP评价研究     

曹伟针  李杰林 《科技广场》2007,(10):35-37

如何科学评价企业技术核心能力,对于企业进行技术创新、建立和保持持续竞争优势、获得最佳的经济效益具有特别重要的意义。根据评价指标体系构建的原则,本文构建了企业技术核心能力评价指标体系,采用了层次分析法(AHP)对评价指标进行了权重分析,并对影响企业技术核心能力的相关因素进行了重要性排序。评价结果有助于研究相关因素的配合,也为企业核心能力的深入研究提供了借鉴。  相似文献

XMage: An image retrieval method based on partial similarity     

Chang-Ryong Kim  Chin-Wan Chung 《Information processing & management》2006

XMage is introduced in this paper as a method for partial similarity searching in image databases. Region-based image retrieval is a method of retrieving partially similar images. It has been proposed as a way to accurately process queries in an image database. In region-based image retrieval, region matching is indispensable for computing the partial similarity between two images because the query processing is based upon regions instead of the entire image. A naive method of region matching is a sequential comparison between regions, which causes severe overhead and deteriorates the performance of query processing. In this paper, a new image contents representation, called Condensed eXtended Histogram (CXHistogram), is presented in conjunction with a well-defined distance function CXSim() on the CX-Histogram. The CXSim() is a new image-to-image similarity measure to compute the partial similarity between two images. It achieves the effect of comparing regions of two images by simply comparing the two images. The CXSim() reduces query space by pruning irrelevant images, and it is used as a filtering function before sequential scanning. Extensive experiments were performed on real image data to evaluate XMage. It provides a significant pruning of irrelevant images with no false dismissals. As a consequence, it achieves up to 5.9-fold speed-up in search over the R*-tree search followed by sequential scanning.  相似文献

Domain analysis and information retrieval through the construction of heliocentric maps based on ISI-JCR category cocitation     

Flix de Moya-Anegn  Benjamín Vargas-Quesada  Zaida Chinchilla-Rodriguez  Elena Corera-lvarez  Victor Herrero-Solana  Francisco J. Munoz-Fernndez 《Information processing & management》2005,41(6):1520-1533

We propose the use of ISI-JCR categories as units of cocitation and measurement for the construction of heliocentric maps. The use of a spatial metaphor allows us to illustrate, analyze and compare domains in terms of the categories and their interconnections or links. We can also move around within the structure of these domains for further analysis, and access the documents associated to the categories and to the links that cocite or relate them.  相似文献   

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

基于AHP-DEMATEL的PPP项目关键成功因素相互关系研究     

张红平  叶苏东 《科技管理研究》2016,(22):203-207

在文献回顾和问卷调查基础上,识别影响PPP项目成功实施的3大影响因素和18个可测量指标。采用AHP和DEMATEL相结合的方法对PPP项目成功实施影响因素间的相互关系进行分析。其中,AHP方法用于获取各因素权重值,DEMATEL方法用于计算各因素之间相互影响程度,两者进行加权计算各因素在系统中的综合影响度并进行排序。研究结果表明,国家法律法规体系的健全、产品/服务质量、市场需求稳定性是PPP项目关键成功因素。一个PPP项目能否顺利实施,最重要的影响因素是项目所在地的经济基础及其所决定的上层建筑。  相似文献
