Abstract

This article examines the public searching of the Web and provides an overview of recent research exploring what we know about how people search the Web. The article reports selected findings from studies conducted from 1997 to 2002 using large-scale Web user data provided by commercial Web companies, including Excite, Ask Jeeves, and AlltheWeb.com. We examined what topics people search for on the Web; how people search the Web using keywords in queries during search sessions; and the different types of searches conducted for multimedia, medical, e-commerce, sex, etc., information. Key findings include changes and differences in search topics over time, including a shift from entertainment to e-commerce searching by largely North American users. Findings show little change in current patterns of Web searching by many users from short queries and sessions. Alternatively, we see more complex searching behaviors by some users, including successive and multitasking searches.

Abstract

Discusses the evolution of online databases during the 1990s considering the effect of cheap information accessed through the Internet. InfoSeek includes Associated Press Online, Reuters Business Report, Commerce Business Daily and Cambridge Scientific Abstracts for a basic 9.95 dollars per month. PR Newswire offers an automated faxback system of press releases at no charge to the caller. CD-ROM directories are making online access almost obsolete. With greater numbers of sophisticated electronic competitors, survival can only be achieved through high quality access, accuracy and added value

Abstract

The desalination industry involves the desalting of sea or brackish water and achieves the purpose of increasing the worls's effective water supply. There are approximately 4.000 desalination Web sites. The six major Internet search engines were used to determine, according to each of the six, the top twenty sites for desalination. Each site was visited and the 120 gross returns were pared down to the final ten - the 'Top Ten'. The Top Ten were then analyzed to determine what it was that made the sites useful and informative. The major attributes were: a) currency (up-to-date); b) search site capability; c) access to articles on desalination; d) newsletters; e) databases; f) product information; g) online conferencing; h) valuable links to other sites; l) communication links; j) site maps; and k) case studies. Reasons for having a Web site and the current status and prospects for Internet commerce are discussed

Abstract

Ecommerce is developing into a fast-growing channel for new business, so a strong presence in this domain could prove essential to the success of numerous commercial organizations. However, there is little research examining ecommerce at the individual customer level, particularly on the success of everyday ecommerce searches. This is critical for the continued success of online commerce. The purpose of this research is to evaluate the effectiveness of search engines in the retrieval of relevant ecommerce links. The study examines the effectiveness of five different types of search engines in response to ecommerce queries by comparing the engines' quality of ecommerce links using topical relevancy ratings. This research employs 100 ecommerce queries, five major search engines, and more than 3540 Web links. The findings indicate that links retrieved using an ecommerce search engine are significantly better than those obtained from most other engines types but do not significantly differ from links obtained from a Web directory service. We discuss the implications for Web system design and ecommerce marketing campaigns.

Abstract

In previous articles, we reported the state of Web searching in 1997 (Jansen, Spink, & Saracevic, 2000) and in 1999 (Spink, Wolfram, Jansen, & Saracevic, 2001). Such snapshot studies and statistics on Web use appear regularly (OCLC, 1999), but provide little information about Web searching trends. In this article, we compare and contrast results from our two previous studies of Excite queries' data sets, each containing over 1 million queries submitted by over 200,000 Excite users collected on 16 September 1997 and 20 December 1999. We examine how public Web searching changing during that 2-year time period. As Table 1 shows, the overall structure of Web queries in some areas did not change, while in others we see change from 1997 to 1999. Our comparison shows how Web searching changed incrementally and also dramatically. We see some moves toward greater simplicity, including shorter queries (i.e., fewer terms) and shorter sessions (i.e., fewer queries per user), with little modification (addition or deletion) of terms in subsequent queries. The trend toward shorter queries suggests that Web information content should target specific terms in order to reach Web users. Another trend was to view fewer pages of results per query. Most Excite users examined only one page of results per query, since an Excite results page contains ten ranked Web sites. Were users satisfied with the results and did not need to view more pages? It appears that the public continues to have a low tolerance of wading through retrieved sites. This decline in interactivity levels is a disturbing finding for the future of Web searching. Queries that included Boolean operators were in the minority, but the percentage increased between the two time periods. Most Boolean use involved the AND operator with many mistakes. The use of relevance feedback almost doubled from 1997 to 1999, but overall use was still small. An unusually large number of terms were used with low frequency, such as personal names, spelling errors, non-English words, and Web-specific terms, such as URLs. Web query vocabulary contains more words than found in large English texts in general. The public language of Web queries has its own and unique characteristics. How did Web searching topics change from 1997 to 1999? We classified a random sample of 2,414 queries from 1997 and 2,539 queries from 1999 into 11 categories (Table 2). From 1997 to 1999, Web searching shifted from entertainment, recreation and sex, and pornography, preferences to e-commerce-related topics under commerce, travel, employment, and economy. This shift coincided with changes in information distribution on the publicly indexed Web.

Abstract

Web Usability konnte sich als Forschungsbereich zunächst nur in größeren Firmen der Internet-Branche wie z. B. Icon Medialab etablieren. Mit zunehmender Konkurrenz und ersten Pleiten im E-Commerce entsteht die Einsicht oder bittere Erfahrung, dass bunte, multimediale Internetpräsenz nicht alles ist: Die Nutzungsqualität von Websites tritt in den Vordergrund und damit ein neuer Arbeitsmarkt für Informationsarchitekten und HCI- bzw. Usability-Spezialisten. Suchmaschinen sind eine besondere Kategorie von Website. Sie entstehen in einem Spannungsfeld zweier unterschiedlicher Interessen: Mit kommerziellen Websites teilen sie den Wettbewerb um Kunden und die Art der Kunden: den ungeduldigen gelegentlichen Anwender. Mit der akademischen Welt teilen sie das forschende Bemühen um die Optimierung von Features und Funktionen und die déformation professionelle der Eingeweihten. Am Beispiel zweier Untersuchungen wird deutlich, wie es der richtige 'Methodenmix' ermöglicht, bei der Evaluation der Nutzungsqualität von Suchmaschinen ganz unterschiedlicher Art (a) diesen Interessenkonflikt bewusst zu machen, (b) Empathie für die Nöte der Kunden zu entwickeln und c) allgemeingültige Kriterien zur Entwicklung gebrauchstauglicher Suchmaschinen aufzustellen. Beide Untersuchungen fanden im Rahmen des Projekts Jorschung und Forschungsumgebung für Web Usability« unter Mitwirkung von Studierenden am Fachbereich Bibliothek und Information der FH Hamburg statt

Abstract

Where Internet users go, attackers follow. Users embrace e-mail; then spammers fill their inboxes with junk mail. With the rise in online commerce, phishers trick them into giving up their passwords. Users find handy downloadable applications; adware vendors bundle them with pop-up-spewing add-ons. The rise of Internet search brings a new type of risk. Hostile Web sites might seek to harm users or take advantage of them - whether through spyware, spam, scams, or other bad practices - because search engines often do not filter these sites from their results. Consider this scenario: Suzy wants to perform Beyonce's Crazy in Love for her school talent show. To make sure she dresses the part, she performs a Google search for >celebrity photos<. When she clicks the first search result, celebritypictures.duble.com, she is quickly prompted to install an adware-bundled ActiveX control in order to browse the site's contents. Eager to view photos of her celebrity role model, she accepts the installation of a new browser toolbar and a pop-up serving adware program. In principle, search engines' listing rules, ranking rules, and advertising policies might shield users from some bad practices, and users' good judgment could protect them from others. But empirically, search engines often lead users to dangerous content. My analysis of search engine safety finds bad practices among approximately 5% of search results for popular keywords, or roughly one site per page of search results.

Abstract

It is important for education in computer science and information systems to keep up to date with the latest development in technology. With the rapid development of the Internet and the Web, many schools have included Internet-related technologies, such as Web search engines and e-commerce, as part of their curricula. Previous research has shown that it is effective to use search engine development tools to facilitate students' learning. However, the effectiveness of these tools in the classroom has not been evaluated. In this article, we review the design of three search engine development tools, SpidersRUs, Greenstone, and Alkaline, followed by an evaluation study that compared the three tools in the classroom. In the study, 33 students were divided into 13 groups and each group used the three tools to develop three independent search engines in a class project. Our evaluation results showed that SpidersRUs performed better than the two other tools in overall satisfaction and the level of knowledge gained in their learning experience when using the tools for a class project on Internet applications development.

Die Suche mit Google, früher meist auf Anhieb erfolgreich, bereitet in letzter Zeit zunehmend Frust. Sucht man zum Beispiel mit den Begriffen "kfz kaufen lüneburg" nach Autohändlern in der Heidestadt, erhält man als ersten Treffer eine Site, die laut Inhaltsangabe in der Trefferliste die Begriffe "Eu-Auto Neuwagenmarkt kaufen Reimport-Auto Fahrzeug" enthält. Als Adresse gibt die Suchmaschine eu-reimport-auto.department1.de/kaufen/ an. Doch dieser Treffer passt nur scheinbar gut zu der Anfrage. Klickt man nämlich auf den Link, landet man nach mehreren Weiterleitungen auf verschiedenen anderen Sites, meistens auf einer allgemeinen Startseite von eBay, http://pages.ebay. de, auf der man dann vergeblich nach "lüneburg" und "kfz" Ausschau hält. Sucht man mit der Abfrage "diascanner test" nach Diascanner-Vergleichen, dann führt der erste Treffer zur Ergebnisseite einer anderen Suchmaschine namens Biveroo mit nutzlosen Verweisen, obwohl der Link angeblich auf die Site www.sisira.de führen soll. Die zweite Site in der Trefferliste listet unter der Domain diascanner.org eBay-Auktionen und Links des Pay-forPerformance-Anbieters Espotting - also gekaufte Links, Werbung. Testberichte? Auch hier Fehlanzeige. Insgesamt finden sich unter den ersten zehn Verweisen nur drei relevante. Surfer erhalten bei Google-Recherchen im Umfeld von Produkten und Dienstleistungen immer mehr unbrauchbare oder in anderer Weise ungewöhnliche Treffer: Webseiten, die mit der Abfrage kaum etwas zu tun haben, zum Teil nicht einmal den Suchbegriff enthalten, wirre Linksammlungen oder gar Ergebnisseiten anderer Suchmaschinen. Mitunter landet man nach dem Klick auch bei einer anderen Adresse, als Googie in seiner Ergebnisliste angibt. Immer seltener finden sich neutrale Informationen; statt dessen landet der Surfer immer häufiger in irgendwelchen Online-Shops oder auf E-Commerce-Portalen. Verseuchte Ergebnisse Die Verseuchung der GoogleSuchergebnisse durch aufdringliche Geschäftemacherei ist findigen Tricksern zu verdanken. Sie haben Wege gefunden, bei immer mehr Suchanfragen ihre Links unter den ersten Treffern zu platzieren. So fällt nun auch Google einer Entwicklung anheim, die viele andere Suchdienste bereits vor Jahren heimgesucht und weitgehend unbrauchbar gemacht hat. Dabei galt doch der geniale Google-Algorithmus zur Bestimmung der Trefferrelevanz ("Ranking") lange Zeit als immun gegen Manipulationsversuche. Der Suchmaschinenprimus zieht nicht nur die in den HTMLSeiten enthaltenen Schlüsselwörter heran, wie es die Suchdienste in der Vor-Google-Ära taten. Stattdessen bestimmen bei Google vor allem Verweise fremder Seiten und damit die Wertschätzung durch andere Webmaster darüber, welche Position eine Website in der Trefferliste erhält. Aber nicht nur die bloße Anzahl der Links, sondern auch der Rang der verweisenden Website fließt in die Bewertung ein. Daraus errechnet Google den so genannten Page Rank, benannt übrigens nach dem Erfinder Larry Page [11. Jedermann kann sich mit der erweiterten Version der Google-Toolbar für den Internet Explorer den Page Rank beliebiger Seiten anzeigen lassen.
