With increasingly higher numbers of non-English language web searchers the problems of efficient handling of non-English Web
documents and user queries are becoming major issues for search engines. The main aim of this review paper is to make researchers
aware of the existing problems in monolingual non-English Web retrieval by providing an overview of open issues. A significant
number of papers are reviewed and the research issues investigated in these studies are categorized in order to identify the
research questions and solutions proposed in these papers. Further research is proposed at the end of each section.

最优二叉树又称Huffman树,其编码源于一些应用中不同符号的相关频数,当两个结点的权值最小且相等时,将造成生成的最优二叉树“形态”不唯一,从而使得编码、译码不能唯一确定.针对Huffman编码此种缺陷,提出了一种唯一确定Huffman编码的新方法,使得字符的Huffman编码是唯一的.最后给出实例以证明此方法的实用性. 相似文献

We explore the causal links between service firms’ knowledge investments, their innovation outputs and business growth based on a bespoke survey of around 1100 UK service businesses. We combine the activity based approach of the innovation value chain with firms’ external links at each stage of the innovation process. This introduces the concept of ‘encoding’ relationships through which learning improves the effectiveness of firms’ innovation processes. Our econometric results emphasise the importance of external openness in the initial, exploratory phase of the innovation process and the significance of internal openness (e.g. team working) in later stages of the process. In-house design capacity is strongly linked to a firm's ability to absorb external knowledge for innovation. Links to customers are important in the exploratory stage of the innovation process, but encoding linkages with private and public research organisations are more important in developing innovation outputs. Business growth is related directly to both the extent of firms’ service innovation as well as the diversity of innovation, reflecting marketing, strategic and business process change. 相似文献

自动组卷策略是利用计算机自动完成试卷生成的一种方案,整个过程的人工投入少,在很大程度上解放了教师,提高了工作效率。能否自动组出满足用户要求的试卷,与组卷使用的算法紧密相关。采用遗传算法,按照选择编码方式、产生初始种群、计算自适应函数、进行遗传操作、试卷生成的过程,可完成自动组卷操作。 相似文献

编码档案著录标准（EAD）的开发、实施和评价 总被引：1，自引：0，他引：1
编码档案著录标准 (EAD) 是档案管理员为改善著录和利用馆藏的方式而开发的一种标准，始于20世纪90年代。EAD以SGML作为编码语言，并以SGML DTD（文件类型定义）形式表示EAD内容与结构。EAD的开发和实施是极为迅速和广泛的,它作为一种档案著录标准，具有很大的发展潜力。本文研究了EAD的起源、结构，分析了EAD的开发和实施现况，并从正反两方面对EAD进行了评价。 相似文献

国外档案编目编码技术标准发展概述 总被引：1，自引：2，他引：1
档案编目编码技术（ＥＡＤ）开发始于２０世纪９０年代。其技术基础是图书目录学的技术标准,包括ＭＡＲＣ、ＭＡＲＣ ＡＭＣ、ＳＧＭＬ、ＴＨＭＬ、ＸＭＬ等。ＥＡＤ的发展使档案在服务观念和服务手段等方面都从传统的“保管”转变到现代信息社会的信息利用上,ＥＡＤ的发展历程说明：人类信息资源共享建设需要来自图书馆、情报学、档案部门以及计算机技术等多种学科领域的共同努力来实现。 相似文献

This study proposes the codification of lexical information in electronic dictionaries, in accordance with a generic and extendable XML scheme model, and its conjunction with linguistic tools for the processing of natural language. Our approach is different from other similar studies in that we propose XML coding of those items from a dictionary of meanings that are less related to the lexical units. Linguistic information, such as morphology, syllables, phonology, etc., will be included by means of specific linguistic tools. The use of XML as a container for the information allows the use of other XML tools for carrying out searches or for enabling presentation of the information in different resources. This model is particularly important as it combines two parallel paradigms—extendable labelling of documents and computational linguistics—and it is also applicable to other languages. We have included a comparison with the labelling proposal of printed dictionaries carried out by the Text Encoding Initiative (TEI). The proposed design has been validated with a dictionary of more than 145 000 accepted meanings. 相似文献
