    We carried out a retrieval effectiveness test on the three major web search engines (i.e., Google, Microsoft and Yahoo). In addition to relevance judgments, we classified the results according to their commercial intent and whether or not they carried any advertising. We found that all search engines provide a large number of results with a commercial intent. Google provides significantly more commercial results than the other search engines do. However, the commercial intent of a result did not influence jurors in their relevance judgments

    What Users See – Structures in Search Engine Results Pages

    This paper investigates the composition of search engine results pages. We define what elements the most popular web search engines use on their results pages (e.g., organic results, advertisements, shortcuts) and to which degree they are used for popular vs. rare queries. Therefore, we send 500 queries of both types to the major search engines Google, Yahoo, Live.com and Ask. We count how often the different elements are used by the individual engines. In total, our study is based on 42,758 elements. Findings include that search engines use quite different approaches to results pages composition and therefore, the user gets to see quite different results sets depending on the search engine and search query used. Organic results still play the major role in the results pages, but different shortcuts are of some importance, too. Regarding the frequency of certain host within the results sets, we find that all search engines show Wikipedia results quite often, while other hosts shown depend on the search engine used. Both Google and Yahoo prefer results from their own offerings (such as YouTube or Yahoo Answers). Since we used the .com interfaces of the search engines, results may not be valid for other country-specific interfaces

    Brand Names as Keywords in Sponsored Search Advertising

    The business models of major Web search engines depend on online advertising, primarily in the form of keyword advertising. In recent years, a controversy has gained notoriety worldwide, in both the international court systems and the media. It concerns a form of potential “bait and switch” advertising where a consumer, searching using the brand name of one company, is presented with an advertisement by a competitor of the searched-for brand. We refer to this practice as “piggybacking.” In the U.S. in particular, the legality of this practice, and the potential liability of the search engines for contributing to trademark infringement, is unclear. However, the eventual resolutions of the issue could significantly and negatively impact the business model of Internet search engines. In this paper, we investigate the actual prevalence of piggybacking of major brands in U.S. search engines. We submitted 100 search queries consisting of top global brand names to three major search engines. Analysis of 2,350 advertisements from search engine results pages showed that just 4 percent were triggered by competitors’ trademarked terms. There was even lower use of those trademark terms in the ad text. Thus, overall competitive piggybacking does not appear to be a deceptive or widespread phenomenon. Implications for this are discussed, and suggestions for future research are presented

    Link-based similarity search to fight web spam

    www.ilab.sztaki.hu/websearch We investigate the usability of similarity search in fighting Web spam based on the assumption that an unknown spam page is more similar to certain known spam pages than to honest pages. In order to be successful, search engine spam never appears in isolation: we observe link farms and alliances for the sole purpose of search engine ranking manipulation. The artificial nature and strong inside connectedness however gave rise to successful algorithms to identify search engine spam. One example is trust and distrust propagation, an idea originating in recommender systems and P2P networks, that yields spam classificators by spreading information along hyperlinks from white and blacklists. While most previous results use PageRank variants for propagation, we form classifiers by investigating similarity top lists of an unknown page along various measures such as co-citation, companion, nearest neighbors in low dimensional projections and SimRank. We test our method over two data sets previously used to measure spam filtering algorithms. 1

    The First 25 Years of the Bled eConference: Themes and Impacts

    Get PDF
    The Bled eConference is the longest-running themed conference associated with the Information Systems discipline. The focus throughout its first quarter-century has been the application of electronic tools, migrating progressively from Electronic Data Interchange (EDI) via Inter-Organisational Systems (IOS) and eCommerce to encompass all aspects of the use of networking facilities in industry and government, and more recently by individuals, groups and society as a whole. This paper reports on an examination of the conference titles and of the titles and abstracts of the 773 refereed papers published in the Proceedings since 1995. This identified a long and strong focus on categories of electronic business and corporate perspectives, which has broadened in recent years to encompass the democratic, the social and the personal. The conference\u27s extend well beyond the papers and their thousands of citations and tens of thousands of downloads. Other impacts have included innovative forms of support for the development of large numbers of graduate students, and the many international research collaborations that have been conceived and developed in a beautiful lake-side setting in Slovenia
