The Internet has changed the information environment in which people involved in scientific work live in slightly over ten years. The purpose of this article is to trace the vector of these changes using several examples, first of all, by the example of linguistics, using the LINGUIST List system as an example. In this paper, different principles of organizing information interaction in science are discussed, which are “vertical information,” principles, being implemented in our country by VINITI RAS and other information services, and the information self-organization of the scientific community, which relies on the network information infrastructure of the Internet. 相似文献

This paper describes the LINGUIST List system, a major international linguistic resource. This system was created by linguists
and for linguists to meet their basic information needs. The system provides a convenient information environment for the
linguistic community and consolidates the latter by its very existence.
This paper is a significant expansion of a part of a report presented at the 7th International Conference “NTI-2007” [1]. 相似文献

缺陷的存在,会影响软件系统的正常使用甚至带来重大危害.为了帮助开发者尽快找到并修复这些缺陷,研究者提出了基于信息检索的缺陷定位方法.这类方法将缺陷定位视为一个检索任务,它为每个缺陷报告生成一份按照程序实体与缺陷相关度降序排序的列表.开发者可以根据列表顺序来审查代码,从而降低审查成本并加速缺陷定位的进程.近年来,该领域的研究工作十分活跃,在改良定位方法和完善评价体系方面取得了较大进展.与此同时,为了能够在实践中更好地应用这类方法,该领域的研究工作仍面临着一些亟待解决的挑战.对近年来国内外学者在该领域的研究成果进行系统性的总结:首先,描述了基于信息检索的缺陷定位方法的研究问题;然后,分别从模型改良和模型评估两方面陈述了相关的研究进展,并对具体的理论和技术途径进行梳理;接着,简要介绍了缺陷定位的其他相关技术;最后,总结了目前该领域研究过程中面临的挑战并给出建议的研究方向. 相似文献

基于统一搜索的信息服务平台 总被引:1,自引:1,他引:0
针对目前多数IT系统的信息服务只具备简单数据查询且资源定位能力薄弱的现状,本文对现有信息服务模式进行了分析,提出了基于信息集成的统一搜索模式。本模式主要包括两部分内容。第一,通过信息集成将分布式异构数据进行提炼、转换和汇总,形成数据全集做为信息源。第二,基于互联网搜索引擎模式和Compass搜索框架,将不同类型、不同粒度和不同主题的信息以统一的方式检索与展示。它的优势在于实现了多种数据源的应用整合并提高了系统可扩展性,更为重要的是极大地提升了用户的信息定位能力,使其获得类似百度或谷歌的使用体验。此模式已被成功应用于中国科学院十一五信息化项目信息管理与服务平台的开发中,获得了良好的应用效果。 相似文献

基于启发式规则的网页主题信息精确定位方法* 总被引:3,自引:0,他引:3
目前大部分的信息抽取方法都是针对主题信息块的提取,没有进一步深入到各个单独主题信息的抽取。针对这一问题,提出了一种基于启发式规则的网页主题信息精确定位方法。首先针对各个单独的主题,分析其多方面的特征,制定出对应的启发式规则;然后利用不同的规则对定位主题重要度不同的这一特点,得到启发式规则的权值矩阵;最后利用基于启发式规则的定位算法精确定位各个主题。将该方法用于网页主题信息抽取系统中,抽取系统能够有效地对各个单独的主题进行定位和抽取。实验结果表明,该方法具有很好的有效性和准确性。 相似文献

缺陷定位是软件调试过程中的重要环节,它通过利用程序信息和测试信息来定位软件中的错误.借助于事件信息量,提出一种基于事件信息量的缺陷定位方法——SIQ(suspiciousness based on information quantity).SIQ方法根据测试信息中不同事件的类型及其发生的概率,结合语句的执行信息,动态计算和调整缺陷定位的结果.通过大量的实验分析和对比,SIQ方法在多个数据集上表现出了很好的稳定性,与几种现有的缺陷定位方法相比,SIQ方法的缺陷定位效果也更加准确. 相似文献

Fast access to information in different languages is still a major problem for many organizations. We have built a multilingual analyst's workstation integrated in the Tipster document management toolkit. The analyst workstation offers to an English-speaking analyst a variety of tools to browse sets of documents in Arabic, Japanese, Spanish and Russian, including a Unicode-based multilingual editor, and a simple machine translation functionality.The Temple project has developed an open multilingual architecture and software support for rapid development of extensible machine translation functionalities. The targeted languages are those for which natural language processing and human resources are scarce or difficult to obtain. The goal is to support rapid development of machine translation functionalities in a very short time with limited resources.Glossary-based machine-translation (GBMT) is used to provide an English gloss of a foreign document. A GBMT system uses a bilingual phrasal dictionary (glossary) to produce a phrase-by-phrase translation. Translation (based on phrase pattern-matching) is fast and accurate regarding the content of the document and browsed documents can be translated almost in real-time. A GBMT system for a language pair is also extremely simple, cheap and fast to develop. Moreover, all language resources used by the system are entirely under the control of the user. 相似文献

Integration of a laboratory information management system (LIMS) with corporate information system elements at an industrial
enterprise based on the Russian Khimik-Analitik LIMS is discussed. Possible implementations of the information interaction
are examined, content and directions of the data flows are determined, and the main problems are described. 相似文献

The paper considers the linguistic basis and algorithmic structure of the system of surface syntactic analysis of the Russian sentence, which is being developed at present at the Institute of Linguistics of the Russian State University for the Humanities. The possibilities of the suggested approach are discussed with regard for the results of experimental realizations of system fragments. The linguistic basis of modules and their program realization may be useful in searching for the solution of particular problems of automatic text analysis and information search. 相似文献

Agriculture-based precise and accurate information needs to be disseminated promptly to farmers so that better decisions such as managing farm fields, making continuous and scientific changes in their production systems and grabbing advantage of market opportunities can be made. In this paper, mobile technology is assessed for the agriculture information dissemination system. A survey has been conducted to find out potential technology, related to the use of the Internet and mobile among farmers in the state of Punjab in India, to deliver agriculture-related information to them. Results show that agricultural information system needs to be developed based on the mass communication technology such as mobile systems. It is also noted that localization and native language of farmers are the concerns to be incorporated into the systems. It has been focused that the use of soft-computing techniques in conjunction with communication networks, for inferring the decision regarding best practices for agricultural activities, is helpful in the development of these systems. 相似文献
