    Abstract
    Project SSG-FI at SUB Göttingen provides special subject gateways to international high quality Internet resources for scientific users. Internet sites are selected by subject specialists and described using an extension of qualified Dublin Core metadata. A basic evaluation is added. These descriptions are freely available and can be searched and browsed. These are now subject gateways for 3 subject ares: earth sciences (GeoGuide); mathematics (MathGuide); and Anglo-American culture (split into HistoryGuide and AnglistikGuide). Together they receive about 3.300 'hard' requests per day, thus reaching over 1 million requests per year. The project SSG-FI behind these guides is open to collaboration. Institutions and private persons wishing to contribute can notify the SSG-FI team or send full data sets. Regular contributors can request registration with the project to access the database via the Internet and create and edit records

    Abstract
    The World Wide Web is a popular and interactive medium used to collect, disseminate, and access an increasingly huge amount of information, which constitutes the mainstay of the so-called information and knowledge society. Because of its spectacular growth, related to both Web resources (pages, sites, and services) and number of users, the Web is nowadays the main information repository and provides some automatic systems for locating, accessing, and retrieving information. However, an open and crucial question remains: how to provide fast and effective retrieval of the information relevant to specific users' needs. This is a very hard and complex task, since it is pervaded with subjectivity, vagueness, and uncertainty. The expression soft computing refers to techniques and methodologies that work synergistically with the aim of providing flexible information processing tolerant of imprecision, vagueness, partial truth, and approximation. So, soft computing represents a good candidate to design effective systems for information access and retrieval on the Web. One of the most representative tools of soft computing is fuzzy set theory. This special topic section collects research articles witnessing some recent advances in improving the processes of information access and retrieval on the Web by using soft computing tools, and in particular, by using fuzzy sets and/or integrating them with other soft computing tools. In this introductory article, we first review the problem of Web retrieval and the concept of soft computing technology. We then briefly introduce the articles in this section and conclude by highlighting some future research directions that could benefit from the use of soft computing technologies.

    Abstract
    Mit über 1100 Delegierten und 85 Ausstellern stellte die zwölfte Information Online auch 2005 wieder die im Raum Asien und Pazifik größte und renommierteste regionale Fachmesse für den Informationsbereich dar. Alle zwei Jahre veranstaltet der australische Informationsberufe-Verband ALIA in Sydney die Tagung mit Fachreferenten aus Australien, Asien, Europa und USA. An drei bis fünf Tagen kommen hier Bibliothekare und Informationsspezialisten aus Australien und Neuseeland, Indien, Malaysien, Amerika, und Europa zusammen, um sich anhand von Vorträgen, Workshops, einer Fachausstellung und reichlich Gelegenheiten für informelles Networking einen Überblick über den sich rasant entwickelnden Markt des elektronischen Informationsmanagement und der Informationsversorgung zu verschaffen. 60 Referenten und neun Hauptredner (Angela Abell, Kate Andrews, Liesle Capper, Peter Crowe, Prof. Brian Fitzgerald, David Hawking, Mary Lee Kennedy, Hemant Manohar, Joan Frye Williams) lieferten Forschungsergebnisse, Fallstudien, Fortschrifttsberichte und programmatische Thesen aus den Themenbereichen Informationsarchitektur, Online Archive, Content Management Systeme, Urheberrecht und WWW, Web Services für Bibliotheken und Informationsstellen, Benutzungsschemata für Web-Technologien, Schnittstellen, Datenpool, Bibliotheksautomation, Referenzservice online, Metadaten für Informationssysteme und für Organisationen, Wissenschaftliches Publizieren, Open Access, Knowledge Management und intellektuelles Kapital, Benutzerpsychologie, Online lernen, Berufsbild Informationsspezialist. Ein Drittel der Beiträge beschäftigte sich mit Fragen rund um Information beziehungsweise Knowledge Discovery Search, Search und nochmals Search. Dreht sich angesichts der kommerziellen Erfolge von Google und Konsorten denn alles nur noch um die Websuche?

    Abstract
    Seit dem Start von Google Scholar als einem neuartigen Suchdienst für wissenschaftliche Literatur (in der englischen Version im November 2004 und in der deutschen Version im April 2006), sorgt dieser Dienst für Gesprächsstoff unter Fachleuten. In diesem Beitrag wird nicht untersucht, wie vollständig Zeitschriftenlisten von Fachdatenbanken oder Verlagen und die Indexierung von Open Access Hochschulschriftenservern durch Google Scholar abgedeckt werden und auch das Pageranking und die Indexierungshäufigkeit von Google Scholar stehen nicht im Fokus, sondern es geht um die praktische Anwendung dieses Suchdienstes bei wissenschaftlichen Literaturrecherchen. Wie müssen Suchanfragen formuliert werden, um thematisch passende Ergebnisse zu bekommen und wie viele relevante Ergebnisse gibt es innerhalb dieser Treffermengen.

    Abstract
    "Die Bayerische Staatsbibliothek testet den semantischen "Discovery Service" Yewno als zusätzliche thematische Suchmaschine für digitale Volltexte. Der Service ist unter folgendem Link erreichbar: https://www.bsb-muenchen.de/recherche-und-service/suchen-und-finden/yewno/. Das Identifizieren von Themen, um die es in einem Text geht, basiert bei Yewno alleine auf Methoden der künstlichen Intelligenz und des maschinellen Lernens. Dabei werden sie nicht - wie bei klassischen Katalogsystemen - einem Text als Ganzem zugeordnet, sondern der jeweiligen Textstelle. Die Eingabe eines Suchwortes bzw. Themas, bei Yewno "Konzept" genannt, führt umgehend zu einer grafischen Darstellung eines semantischen Netzwerks relevanter Konzepte und ihrer inhaltlichen Zusammenhänge. So ist ein Navigieren über thematische Beziehungen bis hin zu den Fundstellen im Text möglich, die dann in sogenannten Snippets angezeigt werden. In der Test-Anwendung der Bayerischen Staatsbibliothek durchsucht Yewno aktuell 40 Millionen englischsprachige Dokumente aus Publikationen namhafter Wissenschaftsverlage wie Cambridge University Press, Oxford University Press, Wiley, Sage und Springer, sowie Dokumente, die im Open Access verfügbar sind. Nach der dreimonatigen Testphase werden zunächst die Rückmeldungen der Nutzer ausgewertet. Ob und wann dann der Schritt von der klassischen Suchmaschine zum semantischen "Discovery Service" kommt und welche Bedeutung Anwendungen wie Yewno in diesem Zusammenhang einnehmen werden, ist heute noch nicht abzusehen. Die Software Yewno wurde vom gleichnamigen Startup in Zusammenarbeit mit der Stanford University entwickelt, mit der auch die Bayerische Staatsbibliothek eng kooperiert.

    Abstract
    This paper uses a mix of qualitative and quantitative methodology to analyse differences between Finnish and American web searchers (n=27 per country) in their choice of initial search strategies (direct address, subject directory and search engines) and their reasoning underlying these choices, with data gathered via a questionnaire. The paper looks at these differences for four types of questions with two variables: closed/open and predictable/unpredictable source of answer (n=16 questions per searcher; total n=864 questions). The paper found significant differences between the two groups' initial search strategies and for three of the four types of questions. The reasoning varied across countries and questions as well, with Finns mentioning fewer reasons although both groups mentioned in aggregate a total of 1,284 reasons in twenty-four reason categories. The reasoning indicated that both country groups considered not only question-related reasons but also source- and search-strategy related reasons in making their decision. The research raises questions about considering cultural differences in designing web search access mechanisms.

    "Let us start with your positive experiences with Google. I have known Google longer than most. At Opera, we were the first to add their search into the browser interface, enabling it directly from the search box and the address field. At that time, Google was an up-and-coming geeky company. I remember vividly meeting with Google's co-founder Larry Page, his relaxed dress code and his love for the Danger device, which he played with throughout our meeting. Later, I met with the other co-founder of Google, Sergey Brin, and got positive vibes. My first impression of Google was that it was a likeable company. Our cooperation with Google was a good one. Integrating their search into Opera helped us deliver a better service to our users and generated revenue that paid the bills. We helped Google grow, along with others that followed in our footsteps and integrated Google search into their browsers. Then the picture for you and for opera darkened. Yes, then things changed. Google increased their proximity with the Mozilla foundation. They also introduced new services such as Google Docs. These services were great, gained quick popularity, but also exposed the darker side of Google. Not only were these services made to be incompatible with Opera, but also encouraged users to switch their browsers. I brought this up with Sergey Brin, in vain. For millions of Opera users to be able to access these services, we had to hide our browser's identity. The browser sniffing situation only worsened after Google started building their own browser, Chrome. ...
    How should Google be regulated? We should limit the amount of information that is being collected. In particular we should look at information that is being collected across sites. It should not be legal to combine data from multiple sites and services. The fact that these sites and services are using the same underlying technology does not change the fact that the user's dealings is with a site at a time and each site should not have the right to share the data with others. I believe this the cornerstone of laws in many countries today, but these laws need to be enforced. Data about us is ours alone and it should not be possible to sell it. We should also limit the ability to target users individually. In the past, ads on sites were ads on sites. You might know what kind of users visited a site and you would place tech ads on tech sites and fashion ads on fashion sites. Now the ads follow you individually. That should be made illegal as it uses data collected from multiple sources and invades our privacy. I also believe there should be regulation as to how location data is used and any information related to our mobile devices. In addition, regulators need to be vigilant as to how companies that have monopoly power use their power. That kind of goes without saying. Companies with monopoly powers should not be able to use those powers when competing in an open market or using their monopoly services to limit competition."

    "Am 18. November 2004 ist die Beta-Version eines neuen Suchdienstes von Google in Betrieb gegangen: Google Scholar (http/scholar.google.com/), das in Zusammenarbeit mit zahlreichen Fachverlagen entstand, soll Studenten und Wissenschaftlern als erste Anlaufstelle bei der Suche nach akademischen Quellen dienen, heißt es bei den Betreibern. Google Scholar erfasst Bücher, wissenschaftliche Abhandlungen, technische Dokumente, Fachzeitschriften und sonstige Literatur, darunter auch Quellen, die via Open Access frei verfügbar sind, zusammen ca. 1,630.000 Dokumente (im Vergleich dazu verzeichnet das Web of Knowledge ca. 18,500.000 und Scopus 26,733,641 Dokumente). Neben Links zu weiterführenden Bibliotheks-Recherchen bieten die Ergebnislisten auch einen Überblick darüber, wie oft das gefundene Dokument in anderen Publikationen zitiert wurde. Die Trefferliste ist nach absteigender Zitierhäufigkeit gereiht; die Treffer werden zusätzlich aufgewertet, wenn sie ihrerseits von vielzitierten Artikeln zitiert werden. Google Scholar kommt vorerst noch ohne Werbung aus, Branchenkenner rechnen aber damit, dass sich die Sparten-Suchmaschine schon bald zu einer profitablen Angelegenheit für die Betreiber entwickeln wird. "Wirtschaftlich zielt der Dienst darauf ab, akademische Inhalte mit Werbung für hochwertige Produkte und Dienstleistungen zu verknüpfen -- und ich glaube das Konzept geht auf", meint John Sack von der Stanford University. Mark Chillingworth meint sogar: "Google Scholar looks like being a bigger headache to AM services like ISI Web of Knowledge and the newly launched Scopus from Elsevier." [!] Die weitere Entwicklung wird zeigen, ob diese Vermutung berechtigt ist. Am 8. Dezember hat die American Chemical Society Klage gegen Google Scholar wegen der Namensähnlichkeit mit dem SciFinder Scholar eingereicht. Google-Sprecher Steve Langdon wollte sich zu dem Sachverhalt nicht im Detail äußern, sagte lediglich, dass sein Unternehmen von der Nutzung des Begriffs Scholar überzeugt ist und die Klage der ACS gegenstandslos ist."

    Abstract
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    Abstract
    The key political and strategic issues which needs to be addressed for the future development of the Australian subject gateways are: continued quality of content creation, integration of access to print and electronic resources, archiving and persistent identification, sustainability of services and service integration. These issues will be more effectively tackled internationally, and the Australian subject gateways are keen to work with international collaborators to achieve a mutually beneficial outcome

    Abstract
    This paper is about search of photos in photo databases of agencies which sell photos over the Internet. The problem is far from the behavior of photo databases managed by librarians and also far from the corpora generally used for research purposes. The descriptions use mainly single words and it is well known that it is not the best way to have a good search. This increases the problem of semantic ambiguity. This problem of semantic ambiguity is crucial for cross-language querying. On the other hand, users are not aware of documentation techniques and use generally very simple queries but want to get precise answers. This paper gives the experience gained in a 3 year use (2006-2008) of a cross-language access to several of the main international commercial photo databases. The languages used were French, English, and German.
