Mining Web-Functional Dependencies For Flexible Information Access, Saverio Perugini, Naren Ramakrishnan
Mining Web-Functional Dependencies For Flexible Information Access, Saverio Perugini, Naren Ramakrishnan
Computer Science Faculty Publications
We present an approach to enhancing information access through Web structure mining in contrast to traditional approaches involving usage mining. Specifically, we mine the hardwired hierarchical hyperlink structure of Web sites to identify patterns of term-term co-occurrences we call Web functional dependencies (FDs). Intuitively, a Web FD ‘x y’ declares that all paths through a site involving a hyperlink labeled x also contain a hyperlink labeled y. The complete set of FDs satisfied by a site help characterize (flexible and expressive) interaction paradigms supported by a site, where a paradigm is the set of explorable sequences therein. …

The Defense Department is transforming information-technology systems into a Global Information Grid (GIG) that will connect sensors to weapons systems and provide unprecedented situational awareness. The authors suggest that if not properly implemented, the GIG may overwhelm war fighters with information presented at the wrong time, at the wrong level of detail, and without proper analysis. This article proposes a model to direct the flow of information in the GIG.

We present the first user study of out-of-turn interaction in menu-based, interactive voice-response systems. Out-ofturn interaction is a technique which empowers the user (unable to respond to the current prompt) to take the conversational initiative by supplying information that is currently unsolicited, but expected later in the dialog. The technique permits the user to circumvent any flows of navigation hardwired into the design and navigate the menus in a manner which reflects their model of the task. We conducted a laboratory experiment to measure the effect of the use of outof- turn interaction on user performance and preference in a …
