“…People dislike having to perform a large amount of manual work to record a trail (De Roure et al, 2001), so we developed a completely automatic method that generated a trail solely from a person's movements through an environment. Our method was evaluated in a virtual building, and showed that there was a significant interaction between the distance traveled during familiarization with the building vs.…”

“…VE trails have presented user's raw movements in the form of virtual footprints, vapor trails, balls of string or breadcrumbs (Darken & Sibert, 1993;Grammenos, Filou, Papadakos, & Stephanidis, 2002;Pettifer, Cook, & Marsh, 2004;Ruddle, 2005). In most cases the trail data has been recorded automatically, rather than expecting a user to specify each waypoint, and this echoes findings from research into information spaces which showed that expecting users to manually identify each item that formed part of a trail was a major limitation of an otherwise successful system (De Roure et al, 2001). Examples of tours in VEs include presenting the path to be followed by a "control" group of participants as a line on the floor of a VE, so that navigation was trivial (e.g., Hartley, Maguire, Spiers, & Burgess, 2003).…”

Generating Trails Automatically, to Aid Navigation When You Revisit an Environment

A new method for generating trails from a person's movement through a virtual environment (VE) is described. The method is entirely automatic (no user input is needed), and uses string-matching to identify similar sequences of movement and derive the person's primary trail. The method was evaluated in a virtual building, and generated trails that substantially reduced the distance participants traveled when they searched for target objects in the building 5–8 weeks after a set of familiarization sessions. Only a modest amount of data (typically five traversals of the building) was required to generate trails that were both effective and stable, and the method was not affected by the order in which objects were visited. The trail generation method models an environment as a graph and, therefore, may be applied to aiding navigation in the real world and information spaces, as well as VEs.

“…For example, Ringo recommends music album and artists based on the word-of-mouth recommendations by weighting users' votes [Shardanand and Maes 1995], GroupLens helps people find Usenet news articles on a collaborative basis [Konstan et al 1997], and MEMOIR assists people in finding other people (rather than documents) with similar interests [DeRoure et al 2001]. However, collaborative filtering approaches also have a number of shortcomings.…”

Recommender systems have been widely advocated as a way of coping with the problem of information overload for knowledge workers. Given this, multiple recommendation methods have been developed. However, it has been shown that no one technique is best for all users in all situations. Thus we believe that effective recommender systems should incorporate a wide variety of such techniques and that some form of overarching framework should be put in place to coordinate the various recommendations so that only the best of them (from whatever source) are presented to the user. To this end, we show that a marketplace, in which the various recommendation methods compete to offer their recommendations to the user, can be used in this role. Specifically, this article presents the principled design of such a marketplace (including the auction protocol, the reward mechanism, and the bidding strategies of the individual recommendation agents) and evaluates the market's capability to effectively coordinate multiple methods. Through analysis and simulation, we show that our market is capable of shortlisting recommendations in decreasing order of user perceived quality and of correlating the individual agent's internal quality rating to the user's perceived quality.

Scalable web page entanglement

We present a proxy-based system for augmenting the capabilities of the World Wide Web. Our system adds two-way association links and automatically removes these links when they break, while the existing web features only one-way links and lingering broken links. Several web augmentation systems have been developed in the past that add two-way links. Our key contribution is in terms of link management, which in our system is dynamic and completely automatic. Links between web pages are added and removed according to popular web traversal paths, freeing both page owners and readers from the burden of link creation and maintenance. Links can form between pages that do not link to each other at all, reflecting the fact that readers have associated these pages with each other-we described such pages as entangled.We use variations on common peer-to-peer techniques to build a scalable system out of a dynamic set of proxy peers. Proxy-to-proxy communication takes place entirely over http, ensuring compatibility with existing infrastructures.A working implementation of our system is available at
