A study of visually linked keywords to support exploratory browsing in academic search

While the search interfaces used by common academic digital libraries provide easy access to a wealth of peer-reviewed literature, their little support for exploratory browsing. When faced with complex task (such as one that requires knowledge discovery), browsing is an important first step in process. To more effectively browsing, we have designed and implemented novel library interface (KLink Search) two new features: visually linked keywords interactive workspace. study potential value these features, conducted controlled laboratory 32 participants, comparing KLink Search baseline modeled after IEEE Xplore. Based on subjective opinions, objective performance, behavioral data, show adding lightweight visual features
