Abstract

Multimedia is proliferating on Web sites, as the Web continues to enhance the integration of multimedia and textual information. In this paper we examine trends in multimedia Web searching by Excite users from 1997 to 2001. Results from an analysis of 1,025,910 Excite queries from 2001 are compared to similar Excite datasets from 1997 to 1999. Findings include: (1) queries per multimedia session have decreased since 1997 as a proportion of general queries due to the introduction of multimedia buttons near the query box, (2) multimedia queries identified are longer than non-multimedia queries, and (3) audio queries are more prevalent than image or video queries in identified multimedia queries. Overall, we see multimedia Web searching undergoing major changes as Web content and searching evolves.

Abstract

Web search engines are beginning to offer access to multimedia searching, including audio, video and image searching. In this paper we report findings from a study examining the state of multimedia search functionality on major general and specialized Web search engines. We investigated 102 Web search engines to examine: (1) how many Web search engines offer multimedia searching, (2) the type of multimedia search functionality and methods offered, such as "query by example", and (3) the supports for personalization or customization which are accessible as advanced search. Findings include: (1) few major Web search engines offer multimedia searching and (2) multimedia Web search functionality is generally limited. Our findings show that despite the increasing level of interest in multimedia Web search, those few Web search engines offering multimedia Web search, provide limited multimedia search functionality. Keywords are still the only means of multimedia retrieval, while other methods such as "query by example" are offered by less than 1% of Web search engines examined.

Abstract

Searching for multimedia is an important activity for users of Web search engines. Studying user's interactions with Web search engine multimedia buttons, including image, audio, and video, is important for the development of multimedia Web search systems. This article provides results from a Weblog analysis study of multimedia Web searching by Dogpile users in 2006. The study analyzes the (a) duration, size, and structure of Web search queries and sessions; (b) user demographics; (c) most popular multimedia Web searching terms; and (d) use of advanced Web search techniques including Boolean and natural language. The current study findings are compared with results from previous multimedia Web searching studies. The key findings are: (a) Since 1997, image search consistently is the dominant media type searched followed by audio and video; (b) multimedia search duration is still short (>50% of searching episodes are <1 min), using few search terms; (c) many multimedia searches are for information about people, especially in audio search; and (d) multimedia search has begun to shift from entertainment to other categories such as medical, sports, and technology (based on the most repeated terms). Implications for design of Web multimedia search engines are discussed.

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.

Footnote

In Hinblick auf die Informationsbedürfnisse ergibt sich eine weitere Besonderheit dadurch, dass Suchmaschinen nicht nur für eine Anfrageform genutzt werden. Eine "Spezialität" der Suchmaschinen ist die Beantwortung von navigationsorientierten Anfragen, beispielsweise nach der Homepage eines Unternehmens. Hier wird keine Menge von Dokumenten oder Fakteninformation verlangt; vielmehr ist eine Navigationshilfe gefragt. Solche Anfragen nehmen weiter zu. Die Untersuchung der Such-Sessions bringt Ergebnisse über die Formulierung und Bearbeitung der Suchanfragen zu einem Informationsbedürfnis zutage. Die Sessions dauern weit überwiegend weniger als 15 Minuten (dies inklusive Sichtung der Dokumente!), wobei etwa fünf Dokumente angesehen werden. Die Anzahl der angesehenen Ergebnisseiten hat im Lauf der Zeit abgenommen; dies könnte darauf zurückzuführen sein, dass es den Suchmaschinen im Lauf der Zeit gelungen ist, die Suchanfragen besser zu beantworten, so dass sich brauchbare Ergebnisse öfter bereits auf der ersten Ergebnisseite finden. Insgesamt bestätigt sich auch hier das Bild vom wenig fortgeschrittenen Suchmaschinen-Nutzer, der nach Eingabe einer unspezifischen Suchanfrage schnelle und gute Ergebnisse erwartet. Der zweite Teil des Buchs widmet sich einigen der bei den Suchmaschinen-Nutzern populären Themen und analysiert das Nutzerverhalten bei solchen Suchen. Dabei werden die eingegebenen Suchbegriffe und Anfragen untersucht. Die Bereiche sind E-Commerce, medizinische Themen, Sex und Multimedia. Anfragen aus dem Bereich E-Commerce sind in der Regel länger als allgemeine Anfragen. Sie werden seltener modifiziert und pro Anfrage werden weniger Dokumente angesehen. Einige generische Ausdrücke wie "shopping" werden sehr häufig verwendet. Der Anteil der E-Commerce-Anfragen ist hoch und die Autoren sehen die Notwendigkeit, spezielle Suchfunktionen für die Suche nach Unternehmenshomepages und Produkten zu erstellen bzw. zu verbessern. Nur zwischen drei und neun Prozent der Anfragen beziehen sich auf medizinische Themen, der Anteil dieser Anfragen nimmt tendenziell ab. Auch der Anteil der Anfragen nach sexuellen Inhalten dürfte mit einem Wert zwischen drei und knapp 1'7 Prozent geringer ausfallen als allgemein angenommen.
Der relativ hohe Wert von 17 Prozent stammt allerdings aus dem Jahr 1997; seitdem ist eine deutliche Abnahme zu verzeichnen. Betont werden muss außerdem, dass Anfragen nach sexuellen Inhalten nicht mit denen nach Pornographie gleichzusetzen sind. Die Suche nach Multimedia-Inhalten hat sich von den allgemeinen Suchinterfaces der Suchmaschinen hin zu speziellen Suchmasken verschoben, die inzwischen von allen großen Suchmaschinen angeboten werden. Die wichtigste Aussage aus den untersuchten Daten lautet, dass die Suche nach Multimedia-Inhalten komplexer und vor allem interaktiver ist als die übliche Websuche. Die Anfragen sind länger und enthalten zu einem deutlich größeren Teil Operatoren. Bei der Bildersuche stellen weiterhin sexuell orientierte Anfragen den höchsten Anteil. Bei der Bilderund Video-Suche sind die Anfragen deutlich länger als bei der regulären Suche; bei der Audio-Suche sind sie dagegen kürzer. Das vorliegende Werk bietet die bisher umfassendste Analyse des Nutzerverhaltens bezüglich der Web-Suche; insbesondere wurden bisher keine umfassenden, auf längere Zeiträume angelegten Studien vorgelegt, deren Ergebnisse wie im vorliegenden Fall direkt vergleichbar sind. Die Ergebnisse sind valide und ermöglichen es Suchmaschinen-Anbietern wie auch Forschern, künftige Entwicklungen stärker als bisher am tatsächlichen Verhalten der Nutzer auszurichten. Das Buch beschränkt sich allerdings auf die US-amerikanischen Suchmaschinen und deren Nutzer und bezieht nur bei All the Web die europäischen Nutzer ein. Insbesondere die Frage, ob die europäischen oder auch deutschsprachigen Nutzer anders suchen als die amerikanischen, bleibt unbeantwortet. Hier wären weitere Forschungen zu leisten."

Abstract

Humans have used electronic information retrieval (IR) systems for more than 50 years as they evolved from experimental systems to full-scale Web search engines and digital libraries. The fields of library and information science (LIS), cognitive science, human factors and computer science have historically been the leading disciplines in conducting research that seeks to model human interaction with IR systems for all kinds of information related behaviors. As technology problems have been mastered, the theoretical and applied framework for studying human interaction with IR systems has evolved from systems-centered to more user-centered, or cognitive-centered approaches. However, cognitive information retrieval (CIR) research that focuses on user interaction with IR systems is still largely under-funded and is often not included at computing and systems design oriented conferences. But CIR-focused research continues, and there are signs that some IR systems designers in academia and the Web search business are realizing that user behavior research can provide valuable insights into systems design and evaluation. The goal of our book is to provide an overview of new CIR research directions. This book does not provide a history of the research field of CIR. Instead, the book confronts new ways of looking at the human information condition with regard to our increasing need to interact with IR systems. The need has grown due to a number of factors, including the increased importance of information to more people in this information age. Also, IR was once considered document-oriented, but has now evolved to include multimedia, text, and other information objects. As a result, IR systems and their complexity have proliferated as users and user purposes for using them have also proliferated. Human interaction with IR systems can often be frustrating as people often lack an understanding of IR system functionality.
