- Abstract
- Indexing remains one of the most popular tools provided by digital libraries to help users identify and understand the characteristics of the information they need. Despite extensive studies of the problem of automatic index construction for text-based digital libraries, the construction of multimedia digital libraries continues to represent a challenge, because multimedia objects usually lack sufficient text information to ensure reliable index learning. This research attempts to tackle the problem of automatic index construction for multimedia objects by employing Web usage logs and limited keywords pertaining to multimedia objects. The tests of two proposed algorithms use two different data sets with different amounts of textual information. Web usage logs offer precious information for building indexes of multimedia digital libraries with limited textual information. The proposed methods generally yield better indexes, especially for the artwork data set.

- Abstract
- Ein Problem der Erstellung von Multimediaanwendungen in Unternehmen ist, dass die Sachkompetenz bezüglich der darzustellenden Inhalte nicht immer bei denjenigen Mitarbeitern liegt, die die Kompetenz für die mediengerechte Aufbereitung haben. Um umfangreiche Hypertextanwendungen - ggf. auch mit interaktiven Aufgaben Lind Multimediaelernenten - zu erzeugen, können Sachautoren von dem Umgang mit Multimediasoftware weitgehend entlastet werden. Der von den Sachautoren verfasste Text ist dazu von vornherein mit minimalen Textauszeichnungen zu versehen. Dazu braucht er seine Textverarbeitung nicht zu verlassen. Um jetzt einen interaktiven Hypertext oder eine 1 lypermediaanwendung mit einzelnen Einträgen und zusätzlichen umfangreichen Navigationskomponenten zu erzeugen und weitere Medien an den jeweils richtigen Stellen einzufügen, ist ein Programm erforderlich, das die Anwendung erzeugen hilft (Engine). Zu den Themen "Hypertext" und "Multimedia" erscheinen etliche Publikationen. Eine Vielzahl von ihnen hat theoretische und konzeptionelle Aspekte zum Inhalt (z. B. Lobin 1999, Brusilovsky 1998, Rouet 1996). Manche betonen den Anwendungsbezug (Gerdes 1997, Hofinann/Simon 1995), der unter besonderer Berücksichtigung für Information oder Ausbildung gesehen werden kann (vgl. Glowalla 1992). Andere sind von historischem Interesse (Nelson 1992), klären die Begrifflichkeit und die Grundlagen (Schnupp 1992, Kuhlen 1991, Seyer 1991, Nielsen 1990, Hashim 1990) oder geben Hinweise auf die Benutzung (MacGrew 1989). Ferner gibt es programmspezifische Literatur, die die technische Handhabung bei der Erstellung unterstützt. Solche Literatur kann genutzt werden, um Aspekte zu gewinnen, die für die Anlage und Ausrichtung einer Hypertextanwendung sinnvoll sind. Werden hingegen existierende Hypertextanwendungen betrachtet, so bleibt der damit verbundene Aufwand und die Organisationsstruktur oft im Dunkeln

- Abstract
- Seit Anfang März 2010 verfügt die Bayerische Staatsbibliothek über eine mobile Version ihres Opacs, den OPACplus mobil. Anstatt einer eigenständigen Anwendung wurde ein Modul entwickelt, das den bestehenden Opac um die für eine mobile Anwendung benötigten Funktionen erweitert.

- Abstract
- Online discussion forums have become a popular medium for users to discuss with and seek information from other users having similar interests. A typical discussion thread consists of a sequence of posts posted by multiple users. Each post in a thread serves a different purpose providing different types of information and, thus, may not be equally useful for all applications. Identifying the purpose and nature of each post in a discussion thread is thus an interesting research problem as it can help in improving information extraction and intelligent assistance techniques. We study the problem of classifying a given post as per its purpose in the discussion thread and employ features based on the post's content, structure of the thread, behavior of the participating users, and sentiment analysis of the post's content. We evaluate our approach on two forum data sets belonging to different genres and achieve strong classification performance. We also analyze the relative importance of different features used for the post classification task. Next, as a use case, we describe how the post class information can help in thread retrieval by incorporating this information in a state-of-the-art thread retrieval model.

- Abstract
- Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

- "Bin gestern im MoMA gewesen. Hab dann noch mal in der Tate vorbeigeschaut. Nachher dann noch einen Abstecher in die Alte Nationalgalerie gemacht. New York, London, Berlin an einem Tag, das ist dank Google kein Problem mehr. Auf der Plattform www.googleartproject.com bietet der Netz-Gigant jetzt einige virtuelle Museumsrundgänge durch einige der bekanntesten und bedeutendsten Häuser der Welt an. Googles neuestes Angebot unterscheidet sich von den in der Regel gut aufgestellten Homepages der Museen vor allem durch die Street-View-Technologie, mit der man von Raum zu Raum und von Bild zu Bild wandeln kann. Dazu hat der Besucher die Möglichkeit, zahlreiche Informationen zu den Kunstwerken abzurufen, oder die Werke in hochauflösenden Vergrößerungen anzuschauen. Aus jeder der teilnehmenden 17 Sammlungen hat Google ein Werk in einer Auflösung von sieben Milliarden Pixeln fotografiert. Wenn man da beim Rundgang durch die Alte Nationalgalerie auf Edouard Manets "Dans la Serre" (Im Wintergarten) trifft und nur einmal den Fingerring des Mannes heranzoomt, wird er gleichsam zur Unkenntlichkeit vergrößert, und man sieht wie unter einem Mikroskop jedes kleinste Detail des Farbauftrags, jeden feinsten Riss. Faszinierend. Auch wenn es das Original nicht ersetzt."

- Abstract
- Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.
