校园网远程教学系统的设计

基于校园网的现状和发展趋势，针对我院远程教学的实际情况，本文提出了实现远程教学系统的方案：采用Linux构建的Web服务器实现异步教学；采用Microsoft的NetMeeting SDK开发基于H．323的网上实时授课系统。     

数字化校园建设与应用

本文从介绍数字化校园建设的现状出发,阐述了目前建设数字化校园的重点任务和方向,提出了数字化校园建设的一般技术实现方法,以及目前建设中要重点注意的问题。     

刑事案件上诉原因文本挖掘——基于二审文书数据

[目的/意义]从刑事二审案件裁判文书中挖掘上诉理由和相关影响因素,给法院和智慧量刑系统提供相关数据。[方法/过程]以北大法宝网近一年的刑事二审案件裁判文书作为基础数据,用信息抽取、word2vec训练词向量和聚类等文本挖掘方法对文本内容进行挖掘。[结果/结论]在传统的上诉理由之外,发现了基于上诉人自身态度的上诉理由。信息抽取、word2vec训练词向量和聚类等文本挖掘方法可用于裁判文书相关内容挖掘。     

试比较莱斯与纽马克的文本类型翻译理论

凯瑟琳娜。莱斯和彼得。纽马克的文本类型为翻译研究做出了巨大的贡献,通过对二者的文本类型理论的认识、对比和分析,二者的翻译理论在翻译的方法、步骤和翻译批评等方面存在差异,该文进行了详细的读解,二者的文本翻译理论研究为翻译学者提供了新的视角。     

Multimedia and Online Video Case Studies for Preservice Teacher Preparation

Case studies have been used successfully as a part of teacher education. There are many possibilities in extending the impact of case studies through the use of technology. Video and the Internet could enable demonstration of more examples, dissemination beyond the walls of the classroom, and discussion between geographically dispersed preservice teachers. Several projects are now investigating the possible ways that technology might enhance or extend text case studies. After exploring four existing products, four essential elements for video case studies are proposed. As video case studies move to the Internet, additional issues arise and these are also explored.     

论语篇翻译与教学

语篇是一个理论概念,我们在翻译活动中面临的是语篇。充分认识语篇概念并将其引入翻译教学是非常有益的。     

基于领域本体的语义文本挖掘研究

为了提高文本挖掘的深度和精度,研究并提出了一种基于领域本体的语义文本挖掘模型.该模型利用语义角色标注进行语义分析,获取概念和概念间的语义关系,提高文本表示的准确度;针对传统的知识挖掘算法不能有效挖掘语义元数据库,设计了一种基于语义的模式挖掘算法挖掘文本深层的语义模式.实验结果表明,该模型能够挖掘文本数据库中的深层语义知识,获取的模式具有很强的潜在应用价值,设计的算法具有很强的适应性和可扩展性.     

Financial information management for university departments,using open-source software

This paper presents a model to analyse the different outcomes generated by the application of Task-Technology Fit (TTF) theory to economic and financial information management in university departments. This model extends that proposed by Goodhue (1995), in two ways: (i) a key role is played by the manager in designing the technology and in performing the task in question. Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.     

高校网络学术影响力实证研究

以重点高校为样本,通过Google Scholar检索并计算样本的网络h指数、网络g指数,并在此基础上计算学术差(g-h)与学术势(g/h)。实证结果发现:网络h指数的区分度不够,配合使用网络g指数及学术差、学术势来共同评价高校的网络学术影响力,效果更好。高校在网络中的学术影响力还有待加强,还需不断加强自身的网站建设,扩大高校学术的公开程度,从而促进自身的发展。     

改进搜索引擎及其数据结构的设计

针对传统搜索引擎在搜索过程中产生的临时文件多、占用磁盘空间大的问题,本文改进了搜索引擎的数据结构,采用索引压缩技术减少了临时文件,提高了检索效率。
