链接是超文本技术的基础。在一系列遵从HTML规范的网页信息结构中,通过网页之间的链接,用户可以在世界各地的站点中自由移动和交互搜索、浏览信息。超文本中的链接标志是由用户的浏览器解释的。每个网页都有确定的URL(统一资源定位符,Uniform Resource Locators)作为网络地址,使得网络浏览器可以链接到特定网络地址的计算机上。  相似文献

随着WWW应用和超文本应用的迅速扩大,标准的通用置标语言近年得到迅速发展。今天标准通用置标语言已普遍应用于电子出版、计算机、军事、航空、制药等各个行业。各发达地区(包括东南亚的日本、新加坡和台湾)的政府和科研部门都给予了足够重视,正大力研究和推广这方面的应用。我国SGML的应用尚未普及,目前的水平还停留在使用HTML创作网页的阶段。本文阐述了使用标准通用置标语言的重要性,介绍了SGML的发展背景和应用状况,讨论了与标准通用置标语言相关的技术要点和未来发展趋势。希望通过本文的介绍,能推动国内这项技术的应用。  相似文献

利用链接关系评价网络信息的可行性研究   总被引:43,自引:3,他引:40  
刘雁书  方平 《情报学报》2002,21(4):401-406
目的 :通过对有代表意义网站的链接特征及站外链接类型及特征的调查分析 ,评价利用链接关系评价网络信息的可行性。方法 :利用搜索引擎FastSearch分别检索综合网站与专业网站的被链次数及新浪被不同类型网页链接次数 ,以分析网站的链接特征 ,并对新浪站外链接类型及其特征进行分析。结果 :综合网站与专业网站被链次数存在明显差异 ,站外链接数在总链接数中所占比例超过站内链接数。新浪被不同语种及不同国别网页广泛链接。站外链接可分为推荐链接、合作链接、相关链接、资源链接、通讯链接、广告链接 6种类型。前 3种类型全部是新浪的主页与频道建立的链接 ,对评价网络信息价值更高。结论 :站外链接关系反映的是被链网页被利用与被推荐的总体情况 ,与被链网页质量存在正向 (肯定 )联系 ,因此利用站外链接评价网络信息是可行的。  相似文献

This study applied the Functional Theory of Political Campaign Discourse to 118 political advertisements (television spots, newspaper ads, direct mail, and WWW pages) from 1998. Acclaims (self‐praise; positive statements) were the most common function (84%), followed by attacks (criticism, negative statements; 15%). Defenses (refutation of attacks) were relatively infrequent (1%). There were some differences by medium (WWW pages had the most acclaims, while television spots had the most attacks; no defenses occurred on WWW pages or in direct mail) but these functions are consistent both across media and with prior research on presidential campaign advertising. Incumbents produced more acclaims than challengers, who attacked more than incumbents. Finally, policy utterances were more common than character utterances in all media but www pages. The overall consistency in Junctions and topics across media and across levels of campaigns (presidential and non‐presidential) strongly suggests the existence of important situational influences on political campaign advertising. These findings can be useful for practitioners, theorists, and critics of campaign discourse.  相似文献

The metastrategy for World-Wide Web information retrieval was presented as an integrated approach to end-user searching in clinical medicine, although its application may be made to any search for WWW information. Certain distinctions, such as between anticipated and unanticipated clinical information needs and between WWW catalogs for retrieving Web sites and WWW databases for retrieving Web pages, were made. These distinctions are important in the end-user strategy because they help maximize the productivity of the WWW for clinicians.  相似文献

The purpose of this study was to assess the websites of American Association of Medical Colleges (AAMC)-member medical schools for the presence of library links. Sixty-one percent (n?=?92) of home pages of the 150 member schools of the AAMC contain library links. For the 58 home pages not offering such links, 50 provided a pathway of two or three clicks to a library link. The absence of library links on 39% of AAMC medical school home pages indicates that the designers of those pages did not consider the library to be a primary destination for their visitors.  相似文献

The currently existing webometric rankings and methods of their analysis are focused primarily on the quantitative measurement of the contents of websites and almost completely ignore the study of the user audience (web traffic). In a pilot project the traffic of ten websites of scientific organizations has been studied with the emphasis on web-traffic sources and the analysis of the traffic of pages with scientific content. It is shown that the direct visits to the site are an indicator of the regular audience of an organization website. This audience consists mainly of the organization’s staff and their immediate colleagues, while new visitors come mainly from search engines. It was revealed that the most visited pages are the ones with information about staff and laboratories, as well as news pages if they are regularly updated. It was found that there is no strong relationship between webometric rankings and website traffic. The rank correlation is moderate and traffic from external links on other websites is weak despite the fact that such links are a key webometric indicator. The results of the study can be used to optimize the structures of the websites of scientific organizations and the analysis of their user audience.  相似文献
