This paper compares alternative user interest models created by aggregating an individual's interest expressed through their interactions with multiple everyday applications. A local service unobtrusively observes user interactions with these applications as well as the content authored, annotated, and consumed in them to understand the user interests expressed through these applications. An open...
World Wide Web is getting dense as many new web pages and resources are created on a daily basis. Keeping track of the changes in the web content has become an immense challenge and is a research problem with a great significance. Even the search engines require to detect changes in the web to keep search indexes up to date. Numerous researches have been carried out on optimizing the change detection...
Digital documents are likely to have problems associated with the persistence of links, especially when dealing with references to external resources. People keep track of various webpages of their interest using distributed digital collections and without possession of these documents; the curator cannot control how they change. In the current context, managing these distributed digital collections...
Web pages at present have become dynamic and frequently changing, compared to the past where web pages contained static content which did not change often. People have the need to keep track of web pages which are of interest to them, using bookmarks in the web browser and continuously keep track of them in order to get the updates. Tracking changes which occur in these bookmarked web pages and getting...
People develop personal information collections consisting of distributed web resources as both reminders that resources exist and to provide rapid access to these resources. Managing such collections is necessary to preserve their value. Unexpected changes within distributed collections can cause them to become outdated, requiring revisions to or removal of no-longer-appropriate resources and replacements...
He Interest Profile Manager (IPM) plays the central role in inferring user interest during document triage. The IPM collects information about interest-related activity from the potentially many triage applications. In this paper, we extend the IPM framework to enable community-based navigation using inferred user interests from information gathering tasks involving the use of multiple applications...
In an effort toward standardization, this paper evaluates the performance of five eye-movement classification algorithms in terms of their assessment of oculomotor fixation and saccadic behavior. The results indicate that performance of these five commonly used algorithms vary dramatically, even in the case of a simple stimulus-evoked task using a single, common threshold value. The important contributions...
