Generating a Topically Focused Virtual-Reality Internet

Surveys highlight that Internet users are frequently frustrated by failing to locate useful information, and by difficulty in browsing anarchically linked web-structures. We present a new Internet browsing application (called VR-net) that addresses these problems. It first identifies semantic domains consisting of tightly interconnected web-page groupings. The second part populates a 3D virtual world with these information sources, representing all relevant pages plus appropriate structural relations. Users can then easily browse through around a semantically focused virtual library

Virtual Browsing Via Deeplinked Catalog Searches

This project facilitates virtual browsing by means of deeplinked catalog searches based on Library of Congress (LC) subject headings and call numbers. Collocating these searches by discipline in pulldown menus opens up the physical book collection in a seamless online fashion to users lacking LC subject heading knowledge, but possessing subject knowledge. Virtual browsing is important because it may aid awareness of and increased use of print collections in large libraries, especially by researchers who rarely visit the library physically

Take Me Out: Space and Place in Library Interactions

Information interactions are strongly affected by the place where they occur. Specific locations are ofen associated with searches on particular topics, and individual users perform different tasks in habituated places. A classic example of habituated space is the commuter who regularly reads the news on the train. This paper investigates these associations through four user studies that examine different uses of place in information interaction. Through this, we reveal the ways in which the location of information interactions makes them effective or ineffective. This extends our interpretation of the role of place in information interaction beyond established foci such as location-based search

Design and Evaluation of a Mobile Photo Gallery in TIP

As a part of the Tourist Information Provider (TIP) system, this project focuses on creating a photo gallery service in the TIP system, which allows users to share, browse and categorize their photos. The core of this project is to provide users a location-based photo browsing. The system provides photos which are taken in the current user's location. We considered privacy control on photos that users uploaded. A photo owner is able to sign an access level to each of their photos and permit different users to access them. We also considered reusing resources. The system allows a user to use an URL of a photo in the system in stead of uploading the photo from the local computer. The system also provides a URL of each photo in order to use the photo on other web places, e.g., Blogs. We use tags and photo metadata Eixf to categorize photos

Virtual WWW Documents: a Concept to Explicit the Structure of WWW Sites

http://www.emse.fr/~beigbeder/PUBLIS/1999-BCS-IRSG-p185-doan-v1.pdfInternational audienceThis paper shows a new concept of a virtual WWW document (VWD), as a set of WWW pages representing a logical information space, generally dealing with one particular domain. The VWD is described using metadata in the XML syntax and will be accessed through a metadata.class file, stored at the root level of WWW sites. We'll suggest how the VWD can improve information retrieval on the WWW and reduce the network load generated by the robots. We describe a prototype implemented in JAVA, within an application in the environmental domain. The exchanges of such metadata lay in a flexible architecture based on two kinds of robots : generalists and specialists that collect and organize this metadata, in order to localize the resources on the WWW. They will contribute to the overall auto-organizing information process by exchanging their indices, therefore forwarding their knowledge each other

VAS (Visual Analysis System): An information visualization engine to interpret World Wide Web structure

People increasingly encounter problems of interpreting and filtering mass quantities of information. The enormous growth of information systems on the World Wide Web has demonstrated that we need systems to filter, interpret, organize and present information in ways that allow users to use these large quantities of information. People need to be able to extract knowledge from this sometimes meaningful but sometimes useless mass of data in order to make informed decisions. Web users need to have some kind of information about the sort of page they might visit, such as, is it a rarely referenced or often-referenced page? This master\u27s thesis presents a method to address these problems using data mining and information visualization techniques

Term-driven E-Commerce

Die Arbeit nimmt sich der textuellen Dimension des E-Commerce an. Grundlegende Hypothese ist die textuelle Gebundenheit von Information und Transaktion im Bereich des elektronischen Handels. Überall dort, wo Produkte und Dienstleistungen angeboten, nachgefragt, wahrgenommen und bewertet werden, kommen natürlichsprachige Ausdrücke zum Einsatz. Daraus resultiert ist zum einen, wie bedeutsam es ist, die Varianz textueller Beschreibungen im E-Commerce zu erfassen, zum anderen können die umfangreichen textuellen Ressourcen, die bei E-Commerce-Interaktionen anfallen, im Hinblick auf ein besseres Verständnis natürlicher Sprache herangezogen werden

Three dimensional visualization of the World Wide Web

Although large-scale public hypermedia structures such as the World Wide Web are popularly referred to as "cyberspace", the extent to which they constitute a space in the everyday sense of the word is questionable. This paper reviews recent work in the area of three dimensional (3D) visualization of the Web that has attempted to depict it in the form of a recognizable space; in other words, as a navigable landscape that may be visibly populated by its users. Our review begins by introducing a range of visualizations that address different aspects of using the Web. These include visualizations of Web structure, especially of links, that act as 3D maps; browsing history; searches; evolution of the Web; and the presence and activities of multiple users. We then summarize the different techniques that are employed by these visualizations. We conclude with a discussion of key challenges for the future

Social information behaviour in Bookshops: implications for digital libraries

We discuss here our observations of the interaction of bookshop customers with the books and with each other. Contrary to our initial expectations, customers do not necessarily engage in focused, joint information search, as observed in libraries, but rather the bookshop is treated as a social space similar to a cafe. Our results extend the known repertoire of collaborative behaviours, supporting further development of models of user tasks and goals. We compare our findings with previous work and discuss possible implications of our observations for the design of digital libraries as places of both information access and social interaction
