- Abstract
- Mit sozialen Suchdiensten - wie z. B. Yahoo Clever, Lycos iQ oder Mister Wong - ist eine Ergänzung und teilweise sogar eine Konkurrenz zu den bisherigen Ansätzen in der Web-Suche entstanden. Während Google und Co. automatisch generierte Trefferlisten bieten, binden soziale Suchdienste die Anwender zu Generierung der Suchergebnisse in den Suchprozess ein. Vor diesem Hintergrund wird in diesem Buch der Frage nachgegangen, inwieweit soziale Suchdienste mit traditionellen Suchmaschinen konkurrieren oder diese qualitativ ergänzen können. Der vorliegende Band beleuchtet die hier aufgeworfene Fragestellung aus verschiedenen Perspektiven, um auf die Bedeutung von sozialen Suchdiensten zu schließen.

- Abstract
- This book discusses many of the key design issues for building search engines and emphazises the important role that applied mathematics can play in improving information retrieval. The authors discuss not only important data structures, algorithms, and software but also user-centered issues such as interfaces, manual indexing, and document preparation. They also present some of the current problems in information retrieval that many not be familiar to applied mathematicians and computer scientists and some of the driving computational methods (SVD, SDD) for automated conceptual indexing

- Abstract
- Presents a state of the art review of WWW search engines from the earliest Internet precursors and noting: prblems inherent in the current range of WWW search engines; problems of searching the WWW (link persistence and lack of integrated search software); and analyzing the resulting search engine types (keyword or directory). Compares search engines of all types across their generic features (database content, retrieval software, and search interface), rather than on a search engine by search engine basis. Considers wider information access issues arising from the nature of the Internet and Web search engines and proposes a general strategy for using web search engines. Comments on the irony that a unitary global information space accessible via 1 freely accessible software package (WWW client browser) should be so balkanized by a plethora of search engines in complete reverse of the traditional world of printed, CD-ROM and online databases, where a limited number and comparatively stable range of search tools attemps to homogenize a large number of physically separate and disparate collections

- Abstract
- The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

- 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
- Der zweite Band des bekannten Handbuchs widmet sich den aktuellen Entwicklungen in der Web-Suche. Neue Such-Ansätze wie die Soziale und die Semantische Suche werden ebenso behandelt wir Spezialsuchen, die Evaluierung und nutzergerechte Gestaltung von Suchdiensten sowie das Monitoring von Webquellen. In 12 Kapiteln geben namhafte Wissenschaftler und Praktiker aus dem deutschsprachigen Raum den Überblick über den State of the Art, zeigen Trends auf und geben Handlungsempfehlungen für alle, die sich als Forscher, Entwickler und Nutzer sich mit dem Thema Suche beschäftigen. Dieser zweite Band erweitert das Themenspektrum des Handbuchs Internet-Suchmaschinen wesentlich und stellt damit eine wertvolle Ergänzung dar.

- Abstract
- Im Rahmen eines Projekts gingen Studierende an der HAW Hamburg für ihre Auftraggeber Lycos Europe und T-Online der Frage nach, wie sich Inhalte aus sozialen Suchdiensten in die algorithmische Suche einbinden lassen. Dazu analysierten und verglichen sie die Vor- und Nachteile der Systeme, die Relevanz der Suchergebnisse, die Benutzerfreundlichkeit sowie die Qualität der Inhalte. Für soziale Software ergaben sich daraus bedeutende Verbesserungspotentiale. Der Text beschreibt die Ergebnisse und die Empfehlungen für Lycos IQ.

- Abstract
- Describes a search engine that integrate text and image search. 1 or more Web site can be indexed for both textual and image information, allowing the user to search based on keywords or images or both. Another problem with the current search engines is that they show the results as pages of scrolled lists; this is not very user-friendly. The search engine allows the user to visualise to results in various ways. Explains the indexing and searching techniques of the search engine and highlights several features of the querying interface to make the retrieval process more efficient. Use examples to show the usefulness of the technology

- Abstract
- Describes the categories and special features of WWW databases and compares them with traditional databases and presents a state of the art review of the literature on the testing and evaluation of WWW based search engines. Describes the different methodologies and measures used in previous studies and summarizes their findings. Presents some evaluative comments on previous studies and suggests areas for future investigation, particularly evaluation of Web based search engines from the end user's perspective

- Abstract
- Describes the concept of a proxy based information classification and filtering utility, named Web Assistant. On the behalf of users a private view of the WWW is generated based on a previously determined profile. This profile is created by monitoring the user anf group activities when browsing WWW pages. Additional features are integrated to allow for easy interoperability workgroups with similar project interests, maintain personal and common hotlists with automatic modification checks and a sophisticated search engine front-end

- Abstract
- The relationship between the methods currently used for indexing the World Wide Web and the programs, languages, and protocols on which the World Wide Web is based is examined. Two methods for indexing the Web are described, directories being briefly discussed while search engines are considered in detail. The automated approach used to create these tools is examined with special emphasis on the parts of a document used in indexing. Shortcomings of the approach are described. Suggestions for effective use of Web search engines are given

- Abstract
- Folksonomies ermöglichen den Nutzern in Kollaborativen Informationsdiensten den Zugang zu verschiedenartigen Informationsressourcen. In welchen Fällen beide Bestandteile des Web 2.0 am besten für das Information Retrieval geeignet sind und wo sie die Websuche ggf. ersetzen können, wird in diesem Beitrag diskutiert. Dazu erfolgt eine detaillierte Betrachtung der Reichweite von Social-Bookmarking-Systemen und Sharing-Systemen sowie der Retrievaleffektivität von Folksonomies innerhalb von Kollaborativen Informationsdiensten.

- Content
- "Ganze "230 Adressen im World Wide Web, 250 Server und 100 per E-Mail zugängliche Informationsquellen". So stand es 1995 in der "Updated Internet Services List". Die manuell zusammengetragene Adressliste, nach ihrem Urheber auch als "Yanoff-Liste" bekannt, war einer der ersten Versuche, die anschwellende Informationsflut des Internet zu kanalisieren. Aus einem dieser Verzeichnisse, das zunächst von Studenten zusammengetragen wurde, entstand kurze Zeit später mit Yahoo die Mutter aller Suchmaschinen. Die englische Wortkombination "Search Engine" ist allerdings irreführend. Denn dahinter steckt in Wahrheit eine Software, die automatisch einen Index der Internetinhalte erstellt. Denn der Fleiß einer Handvoll Studenten reichte schon bald nicht mehr aus, das sich explosionsartig ausbreitende Web auch nur ansatzweise zu erfassen.
Keine ernsthafte Konkurrenz Damit ist die Geschichte der Suchmaschinen weitestgehend erzählt - außer, dass Yahoo praktisch keine Rolle mehr spielt. Um das Gesuchte in den Weiten des Netzes zu finden, benutzt man heute Google. Mehr als 90 Prozent aller Suchanfragen in Deutschland laufen Schätzungen zufolge über die Rechenzentren des US-Konzerns. Ernsthafte Konkurrenten? Keine. Einst erfolgreiche Dienste wie Excite, Infoseek, AltaVista oder Lycos sind längst von der Bildfläche verschwunden. Liefert nicht Google zu allen erdenklichen Suchbegriffen zigtausend Ergebnisse? Mehr, so die allgemeine Auffassung, kann sowieso kein Mensch verarbeiten. Dahinter steht der naive Glaube, Google bilde die digitale Welt in ihrer Gesamtheit ab. Oder, schlimmer noch, gar die reale Welt. Dabei könnte nichts weiter von der Realität entfernt sein, wie Dr. Wolfgang Sander-Beuermann, Leiter des Suchmaschinenlabors der Leibniz-Universität Hannover erklärt. Denn Google entscheidet, nach welchen Kriterien die digitale Welt durchkämmt wird. Google legt fest, welche Webseiten unter den ersten zehn Ergebnissen zu einer Suche angezeigt werden. Da die Mehrheit der Nutzer ohnehin nur diese wahrnimmt, bestimmt ein einzelnes Unternehmen, welchen Ausschnitt der Wirklichkeit die Menschheit zu sehen bekommt. Und die Algorithmen, nach denen die Suchmaschine funktioniert, hält der Konzern streng unter Verschluss: "Google entscheidet, welches Wissen wahrgenommen wird, und welches nicht; was im Internet existiert und was nicht." Die Macht, die dem Konzern damit zukomme, reiche weit über die Kontrolle des Wissenszugangs durch Suchmaschinen hinaus. "Was wir hier beobachten, ist eine Monokultur mit gravierenden Folgen für die Informations- und Wissenskultur", warnt der Wissenschaftler, der deshalb bereits vor Jahren "SuMa e.V.", einen "Verein für freien Wissenszugang", gegründet hat. Er setzt sich dafür ein, "globale Online-Oligopole besser zu kontrollieren". Um den freien Zugang zu dem im Internet gespeicherten Wissen für möglichst viele Menschen zu ermöglichen, sei es außerdem "von entscheidender Bedeutung, die dahinterstehende Technologie zu entwickeln und zu fördern - auch und gerade in Deutschland." Doch genau das wurde in den vergangenen zehn Jahren versäumt.
Und natürlich schlägt Microsoft in die gleiche Kerbe wie Google. Denn auch die Bing-Suche steht ganz im Zeichen der "Individualisierung" der Ergebnisse. "Social Search" nennt sich die (noch) optionale Möglichkeit, Facebook-Einträge von Freunden als Suchkriterien zu verwenden. Schließlich, so die Meinung des Konzerns, beeinflusse der "Freunde-Effekt" die Entscheidung von Menschen in der Regel mehr als andere Faktoren. Die Entwicklung zeigt eindrucksvoll, wie schnell sich die beiden letzten Großen im Suchmaschinen-Geschäft neue Entwicklungen im Netz aneignen. Im Web 2.0 bildeten Blogs und Soziale Netzwerke bislang gewissermaßen ein demokratisches Gegengewicht zum Meinungsmonopol. Doch auch hier ist der Internet-Goliath bereits am Start. Wer sich schon immer mal gefragt hat, warum der Such-Gigant praktisch monatlich mit neuen Angeboten wie etwa Google+ aufwartet, findet hier eine Antwort. Mit dem kostenlosen Smartphone-Betriebssystem Android sicherte man sich eine gewichtige Position auf dem expandieren Markt für mobile Plattformen. Trotz ihrer momentanen Allmacht erkennen die Konzernlenker also durchaus die Gefahr, irgendwann einmal selbst vom Zug der Zeit überrollt zu werden. Für die meisten Konkurrenten kommt diese Einsicht zu spät."
