- Abstract
- Surfing the World Wide Web used to be cool, dude, real cool. But things have gotten hot - so hot that finding something useful an the Web is no longer cool. It is suffocating Web searchers in the smoke and debris of mountain-sized lists of hits, decisions about which search engines they should use, whether they will get lost in the dizzying maze of a subject directory, use the right syntax for the search engine at hand, enter keywords that are likely to retrieve hits an the topics they have in mind, or enlist a browser that has sufficient functionality to display the most promising hits. When it comes to Web searching, in a few short years we have gone from the cool image of surfing the Web into the frying pan of searching the Web. We can turn down the heat by rethinking what Web searchers are doing and introduce some order into the chaos. Web search strategies that are tool-based-oriented to specific Web searching tools such as search en gines, subject directories, and meta search engines-have been widely promoted, and these strategies are just not working. It is time to dissect what Web searching tools expect from searchers and adjust our search strategies to these new tools. This discussion offers Web searchers help in the form of search strategies that are based an strategies that librarians have been using for a long time to search commercial information retrieval systems like Dialog, NEXIS, Wilsonline, FirstSearch, and Data-Star.

- Abstract
- Das Herausfinden und Lösen verschiedener Nutzerbedürfnisse als Hauptthema der Konferenz warf gleich mehrere Fragen auf: Erstens, wer sind die Nutzer? Zweitens, was wollen sie? Und wer beurteilt das und aus welcher Sicht? Welche Auswirkungen haben die realisierten Maßnahmen? Die etwa 200 Teilnehmer aus neun Nationen, davon 21 aus europäischen Ländern, davon drei aus Deutschland, wurden in sechs Vortragsblöcken mit einer Vielzahl von Aspekten konfrontiert, die wie so oft in unserer rasanten Entwicklung im IT-Bereich nur Lösungsansätze aufzeigten oder die Schwierigkeiten mit den Angeboten. Herausragendes Merkmal war der mehrfache Bezug auf die Marke "Google"!

- Abstract
- Because of the increasing presence of scientific publications an the Web, combined with the existing difficulties in easily verifying and retrieving these publications, research an techniques and methods for retrieval of scientific Web publications is called for. In this article, we report an the initial steps taken toward the construction of a test collection of scientific Web publications within the subject domain of plant biology. The steps reported are those of data gathering and data analysis aiming at identifying characteristics of scientific Web publications. The data used in this article were generated based an specifically selected domain topics that are searched for in three publicly accessible search engines (Google, AlITheWeb, and AItaVista). A sample of the retrieved hits was analyzed with regard to how various publication attributes correlated with the scientific quality of the content and whether this information could be employed to harvest, filter, and rank Web publications. The attributes analyzed were inlinks, outlinks, bibliographic references, file format, language, search engine overlap, structural position (according to site structure), and the occurrence of various types of metadata. As could be expected, the ranked output differs between the three search engines. Apparently, this is caused by differences in ranking algorithms rather than the databases themselves. In fact, because scientific Web content in this subject domain receives few inlinks, both AItaVista and AlITheWeb retrieved a higher degree of accessible scientific content than Google. Because of the search engine cutoffs of accessible URLs, the feasibility of using search engine output for Web content analysis is also discussed.

- Abstract
- Designing systematic access to Internet resources is a major item an the agenda of researchers and practitioners in the field of information science, and is the focus of this study. A critical analysis of classification schemes used in major portals and Web classified directories exposes inconsistencies in the way they classify Internet resources. The inconsistencies indicate that the developers fall to differentiate the various classificatory models, and are unaware of their different rationales. The study establishes eight classificatory models for resources available to Internet users. Internet resources can be classified by subjects, objects, applications, users, locations, reference sources, media, and languages. The first five models are contentrelated; namely they characterize the content of the resource. The other three models are formst-related; namely they characterize the format of the resource or its technological infrastructure. The study identifies and formulates the eight classificatory models, analyzes their rationales, and discusses alternative ways to combine them in a faceted integrated classification scheme.

- 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
- Das Internet hat die Welt von Information, Kommunikation und Medien nachhaltig verändert. Suchmaschinen spielen dabei eine zentrale Rolle. Sie bilden das Tor zum Meer der elektronisch verfügbaren Informationen, leisten dem Nutzer wertvolle Hilfe beim Auffinden von Inhalten, haben sich zwischenzeitlich zum Kristallisationspunkt für vielfältige ergänzende Informations-, Kommunikations- und Mediendienste entwickelt und schicken sich an, Strukturen und Strategien der beteiligten Branchen umzuwälzen. Dabei ist die dynamische Entwicklung der Such- und Finde-Technologien für das Internet weiterhin in vollem Gange. Der MÜNCHNER KREIS hat vor diesem Hintergrund mit exzellenten Fachleuten aus Wirtschaft und Wissenschaft die Entwicklungen analysiert und die Zukunftsperspektiven diskutiert. das vorliegende Buch enthält die Ergebnisse.

- Abstract
- The dominant method currently used to improve the quality of Internet search systems is often called "digital democracy." Such an approach implies the utilization of the majority opinion of Internet users to determine the most relevant documents: for example, citation index usage for sorting of search results (google.com) or an enrichment of a query with terms that are asked frequently in relation with the query's theme. "Digital democracy" is an effective instrument in many cases, but it has an unavoidable shortcoming, which is a matter of principle: the average intellectual and cultural level of Internet users is very low- everyone knows what kind of information is dominant in Internet query statistics. Therefore, when one searches the Internet by means of "digital democracy" systems, one gets answers that reflect an underlying assumption that the user's mind potential is very low, and that his cultural interests are not demanding. Thus, it is more correct to use the term "digital ochlocracy" to refer to Internet search systems with "digital democracy." Based an the well-known mathematical mechanism of linear programming, we propose a method to solve the indicated problem.

- Abstract
- This study examines the influence of time constraints on Internet and Web search goals and search behavior. Specifically, it looks at the searching behavior of public library Internet users who, previously limited to 30 minutes per Internet session, are given an unlimited amount of time for use. Interviews and observations were conducted with 34 participants searching on their own queries. Despite an increase in the time allowed for searching, most people spent less than 30 minutes on the Internet, carrying out tasks like paying bills, shopping, browsing, and making reservations. Those who took more than 30 minutes were looking for jobs or browsing. E-mail use was universal. In this context, influences like time-dependent and time-independent tasks, use of search hubs to perform more efficient searches, and search diversity were recorded. Though there are a number of large and small studies of Internet and Web use, few of them focus on temporal influences. This study extends knowledge in this area of inquiry.

- Abstract
- Queries submitted to the Excite search engine were analyzed for subject content based on the cooccurrence of terms within multiterm queries. More than 1000 of the most frequently cooccurring term pairs were categorized into one or more of 30 developed subject areas. Subject area frequencies and their cooccurrences with one another were tallied and analyzed using hierarchical cluster analysis and multidimensional scaling. The cluster analyses revealed several anticipated and a few unanticipated groupings of subjects, resulting in several well-defined high-level clusters of broad subject areas. Multidimensional scaling of subject cooccurrences revealed similar relationships among the different subject categories. Applications that arise from a better understanding of the topics users search and their relationships are discussed

- Abstract
- Adapting the consumer behavior selectivity model to the Web environment, this paper's key contribution is the introduction of a self-concept orientation model of Web information seeking. This model, which addresses gender, effort, and information content factors, questions the commonly assumed equivalence of sex and gender by specifying the measurement of gender-related selfconcept traits known as self- and other-orientation. Regression analyses identified associations between self-orientation, other-orientation, and self-reported search frequencies for content with identical subject domain (e.g., medical information, government information) and differing relevance (i.e., important to the individual personally versus important to someone close to him or her). Self- and other-orientation interacted such that when individuals were highly self-oriented, their frequency of search for both self- and other-relevant information depended on their level of other-orientation. Specifically, high-self/high-other individuals, with a comprehensive processing strategy, searched most often, whereas high-self/low-other respondents, with an effort minimization strategy, reported the lowest search frequencies. This interaction pattern was even more pronounced for other-relevant information seeking. We found no sex differences in search frequency for either self-relevant or other-relevant information.

- Abstract
- The Internet can be a valuable tool allowing distance learners to access information not available locally. Search engines are the most common means of locating relevant information an the Internet, but to use them efficiently students should be taught the basics of searching and how to evaluate the results. This article briefly reviews how Search engines work, studies comparing Search engines, and criteria useful in evaluating the quality of returned Web pages. Research indicates there are statistical differences in the precision of Search engines, with AltaVista ranking high in several studies. When evaluating the quality of Web pages, standard criteria used in evaluating print resources is appropriate, as well as additional criteria which relate to the Web site itself. Giving distance learners training in how to use Search engines and how to evaluate the results will allow them to access relevant information efficiently while ensuring that it is of adequate quality.

- Abstract
- Enormous expanses of the Internet are unreachable with standard Web search engines. This book provides the key to finding these hidden resources by identifying how to uncover and use invisible Web resources. Mapping the invisible Web, when and how to use it, assessing the validity of the information, and the future of Web searching are topics covered in detail. Only 16 percent of Net-based information can be located using a general search engine. The other 84 percent is what is referred to as the invisible Web-made up of information stored in databases. Unlike pages on the visible Web, information in databases is generally inaccessible to the software spiders and crawlers that compile search engine indexes. As Web technology improves, more and more information is being stored in databases that feed into dynamically generated Web pages. The tips provided in this resource will ensure that those databases are exposed and Net-based research will be conducted in the most thorough and effective manner. Discusses the use of online information resources and problems caused by dynamically generated Web pages, paying special attention to information mapping, assessing the validity of information, and the future of Web searching.

- Abstract
- This paper presents a comparative study of six French-language Web directories (MSN, Nomade, Open Directory, Voila, Voila Pages Perso, and Yahoo). The study focuses an the quantitative and qualitative aspects of the organization of these directories, and an the way in which they describe sites. It reveals a wide variety of structures, content and organizational principles. In this respect, Web directories do not correspond to classic theories of classification. They highlight the difficulty of proposing a structured representation of the heterogeneous content of the Web.
