Explicit Passive Analysis in Electronic Catalogs
We consider example-critiquing systems that help people search for their most preferred item in a large catalog. We compare 6 existing approaches in terms of user or system-centric, implicit or explicit use of preferences, assumptions used and their behavior in underconstrained and overconstrained situations. We consider several types of explicit passive analysis to guide the users in their search, that is, information offered to the user about his current search but without any action taken by the system. We suggest that such a user-centric system together with the right analysis makes the users feel more confident in their decision and reduces session time and cognitive effort. We have implemented a prototype to evaluate the impact of explicit passive analysis in (1) a query-building and (2) a preference-based approach
Ariadne: An interface to support collaborative database browsing:Technical Report CSEG/3/1995
This paper outlines issues in the learning of information searching skills. We report on our observations of the learning of browsing skills and the subsequent iterative development and testing of the Ariadne system – intended to investigate and support the collaborative learning of search skills. A key part of this support is a mechanism for recording an interaction history and providing students with a visualisation of that history that they can reflect and comment upon

Union Catalogs in a Changing Library World: An Introduction
The Andrew W. Mellon Foundation and the National Library of Estonia organized a Conference on Union Catalogs which took place in Tallinn, in the National Library of Estonia on October 17–19, 2002. The Conference presented and discussed analytical papers dealing with various aspects of designing and implementing union catalogs and shared cataloging systems as revealed through the experiences of Eastern European, Baltic and South African research libraries. Here you can find the texts of the conference papers and the list of contributors and participants.The Andrew W.

Interactive product catalogue with user preference tracking
In the context of m-commerce, small screen size poses serious difficulty for users to browse effectively through a product catalogue, given the limited number of products that may be presented on-screen. Despite the availability of search engines, filters and recommender systems to aid users, these techniques focus on a narrow segment of product offering. The users are thus denied the opportunity to do a more expansive exploration of the products available. This paper describes a novel approach to overcome the constraints of small screen size. Through integration of a product catalogue with a recommender system, an adaptive system has been created that guides users through the process of product browsing. An original technique has been developed to cluster similar positive examples together to identify areas of interest of a user. The performance of this technique has been evaluated and the results proved to be promising
Snipers, Shills, and Sharks eBay and Human Behavior
Every day on eBay, millions of people buy and sell a vast array of goods, from rare collectibles and antiques to used cars and celebrity memorabilia. The internet auction site is remarkably easy to use, which accounts in part for its huge popularity. But how does eBay really work, and how does it compare to other kinds of auctions? These are questions that led Ken Steiglitz--computer scientist, collector of ancient coins, and a regular eBay user--to examine the site through the revealing lens of auction theory. The result is this book, in which Steiglitz shows us how human behaviors in open markets like eBay can be substantially more complex than those predicted by standard economic theory. In these pages we meet the sniper who outbids you in an auction's closing seconds, the early bidder who treats eBay as if it were an old-fashioned outcry auction, the shill who bids in league with the seller to artificially inflate the price--and other characters as well. Steiglitz guides readers through the fascinating history of auctions, how they functioned in the past and how they work today in online venues like eBay. Drawing on cutting-edge economics as well as his own stories from eBay, he reveals practical auction strategies and introduces readers to the fundamentals of auction theory and the mathematics behind eBay. Complete with exercises and a detailed appendix, this book is a must for sophisticated users of online auctions, and essential reading for students seeking an accessible introduction to the study of auction theory.eBay, auctions, auction theory, human behavior, open markets, strategies, English auctions, Vickrey auctions

Recommender Systems for Scientific and Technical Information Providers
Providers of scientific and technical information are a promising application area of recommender systems due to high search costs for their goods and the general problem of assessing the quality of information products. Nevertheless, the usage of recommendation services in this market is still in its infancy. This book presents economical concepts,
statistical methods and algorithms, technical architectures, as well as experiences from case studies on how recommender systems can be integrated
College Students' Credibility Judgments in the Information-Seeking Process
Part of the Volume on Digital Media, Youth, and CredibilityThis chapter presents an in-depth exploration of how college students identify credible information in everyday information-seeking tasks. The authors find that credibility assessment is an over-time process rather than a discrete evaluative event. Moreover, the context in which credibility assessment occurs is crucial to understand because it affects both the level of effort as well as the strategies that people use to evaluate credibility. College students indicate that although credibility was an important consideration during information seeking, they often compromised information credibility for speed and convenience, especially when the information sought was less consequential
