百度竞价排名搜索推广机制的性质认定问题一直存在较大争议,本文通过分析“魏则西事件”认为搜索引擎推广服务是通过互联网技术进行的特定搜索行为,这种行为从形式和效果上看,均在一定程度上反映了广告特性。百度搜索推广服务,是以技术来伪装的互联网广告,是互联网领域的新型广告营销形式,应当按互联网广告的规定处理,百度可以认定为广告发布者。  相似文献

模糊综合评判法在图书评标中的应用研究   总被引:4,自引:1,他引:3  
相对于综合评分法而言,模糊综合评判法更适用于评价定性指标,可以将招标中用模糊语言描述的定性属性或信息定量化,较好地克服信息的模糊性,减少招标中的不确定性问题。其模型更为科学严谨,并在一定程度上限制了主观因素对评标的影响,在图书评标中运用模糊综合评判法则更能使评标结果趋于客观、准确、合理。本文结合案例详细介绍了在图书评标中应用模糊综合评判法进行系统评价的建模方法和步骤。  相似文献

ABSTRACT

Search engine use is one of the most popular online activities. According to a recent OCLC report, nearly all students start their electronic research using a search engine instead of the library Web site. Instead of viewing search engines as competition, however, librarians at Binghamton University Libraries decided to employ search engine optimization strategies to make their Web site more visible on the search engine result pages. Although search engine optimization is used frequently by commercial Web sites, few libraries have attempted to optimize their own sites. This article describes Binghamton University's experiences in developing and implementing an optimization pilot project. The research presented in this article has importance for libraries who may be considering an optimization project for their own sites.  相似文献

E-mail-alerting system of online databases is a new trend catching up fast with researchers. Results of auto-run set queries are informed through e-mails as ‘alerts’ to the registered user. Even though e-mail-alerting systems are quite popular amongst Internet users, their inherent advantages remain unexplored in the Indian scenario. An effort to explore all such features available in the ScienceDirect online database has been made in this paper. The process of registration for activating e-mail alerts, customizing a home page, selecting favorite journals, search alerts, journal issue alerts, citation alerts and search history are briefed with screen shot examples. The study emphasizes the fact that librarians and information Science professionals should take lead roles in unveiling all such possible features available in various online databases. They should also make efforts at informing the user community of the utility of such features in a bid to enhance the research output.  相似文献

The following study analyzes user search behavior using a tabbed-search interface. For this study, a transaction log was used to collect information about user searches and included tab used; search terms; date, time, and location of search (on campus or off campus); as well as a unique ID to identify the user session and another ID to identify each transaction. This article explains the process for examining 4,300 search queries conducted on the library homepage during an academic semester and presents findings from the analysis. The article also details enhancements that were made to the tabbed-search interface as a result of the transaction log analysis. Additionally, the article discusses the merits of using a transaction log as a method of ongoing assessment of a library Web site's search interface.  相似文献

This article summarizes the author's dissertation regarding search strategies of millennial undergraduate students in Web and library online information retrieval systems. Millennials bring a unique set of search characteristics and strategies to their research since they have never known a world without the Web. Through the use of search engines, they have come to expect that searches can be completed using an easy, single search box that produces complete articles on just about any topic. However, the reliability and quality of much of the information on the Web is questionable. Conversely, information that resides in library information retrieval systems is often of high scholarly content, but there is not a single, user-friendly system for millennials to use. A case study investigation was conducted at the State University of New York at Oswego, a public undergraduate university in Central New York. The goal of the study was to identify the search strategies of a sampling of millennial undergraduate students in both Web information retrieval systems and library information retrieval systems in order to expand upon existing theories about millennials and to suggest interface design enhancements, which could make online library information retrieval systems easier for millennials to use. The findings recommend improving database search functionality, such as natural-language searching, spell-checking, and uniform full-text wording and placement. Results also suggested that increasing the availability of full-text articles would contribute to millennials’ use of library information retrieval systems.  相似文献
