BACKGROUND Users searching for health information on the Internet may be searching for their own health issue, searching for someone else's health issue, or browsing with no particular health issue in mind. Previous research has found that these three categories of users focus on different types of health information. However, most health information websites provide static content for all user...

This paper describes two empirical experiments investigating the perception of embedded audible hyperlinks, designed using speech and non-speech cues, and their effect on the comprehension of synthetic speech. Results from the first experiment showed high accuracy levels of hyperlink perception and differences in comprehension performance between sentences with hyperlinks and sentences without ...

We introduce a set of new metrics for hyperlink quality. These metrics are based on users’ interactions with hyperlinks as recorded in click logs. Using a year-long click log, we assess the INEX 2008 link discovery (Link-the-Wiki) runs and find that our metrics rank them differently from the existing metrics (INEX automatic and manual assessment), and that runs tend to perform well according to...

Quantitative modeling has revolutionized modern biology. The ability to reduce biological processes to sets of equations enables us to reproduce many features of the living system: complex nonlinear systems can defy intuition, and sometimes the best way to put a given finding into perspective is to simulate it. More importantly, quantitative modeling can yield emergent insights. We do our best ...

The hyperlinking feature of hypertext, which in the cognitive flexibility perspective encourages advanced learning (Spiro & Jehng, 1990), frequently overloads working memory according to the cognitive load theory (Sweller, 1988). One of such negative effects of hyperlinks is split attention. When two or more sources of information are separated in space (e.g., text located on different hypertex...
