Exploratory search is becoming more common as the web is used more increasingly as a medium for learning and discovery. Compared to traditional known-item search, exploratory search is more challenging and difficult to support because it initiates with poorly defined search goals, while the user knowledge and information-needs constantly change throughout the search process. Although informatio...

Post-weaning mice fed exclusively milk display low-frequency exploratory behavior [Ishii, T., Itou, T., and Nishimura, M. (2005) Life Sci. 78, 174-179] compared to mice fed a food pellet diet. This low-frequency exploratory behavior switched to high-frequency exploration after a switch from exclusively milk formula to a food pellet diet. Acquisition of the high-frequency exploratory behavior wa...

Exploratory search systems (ESSs) are search engines that help users to explore a topic of interest. A shortcoming of current evaluation methods is that they cannot be used to determine if an ESS can help the user in performing exploratory search tasks. To address this issue, we introduce our approach for designing a user-centered evaluation method for ESSs. Our method takes into account users’...

Individual zebrafish Danio rerio were assayed for exploratory tendency in a serial open field test before and after being maintained on one of four diet treatments that differed in ration and in predictability of food delivery. Danio rerio became more exploratory after being maintained on a diet with a predictable delivery schedule. There was no effect of ration. Thus, exploratory behaviour is ...

Narrative-centered learning environments offer significant potential for supporting guided exploratory learning. By taking advantage of the inherent structure of narrative, narrative-centered environments provide students with engaging worlds in which they actively participate in motivating story-based problemsolving activities. Two key challenges posed by narrativecentered environments for gui...

There exist various approaches in software testing to test software under development. Exploratory Testing is one such important approach where no predefined test cases are used to test the software. It is proven by researchers that exploratory testing is equally effective in detecting defects as the traditional testing where predefined test cases are used to test the software. Hence, this pape...

Advances in qPCR technology allow studies of increasingly large systems comprising many genes and samples. The increasing data sizes allow expression profiling both in the gene and the samples dimension while also putting higher demands on sound statistical analysis and expertise to handle and interpret its results. We distinguish between exploratory and confirmatory statistical studies. In thi...

When encountering novel environments, animals perform complex yet structured exploratory behaviors. Despite their typical structuring, the principles underlying exploratory patterns are still not sufficiently understood. Here we analyzed exploratory behavioral data from two modalities: whisking and locomotion in rats and mice. We found that these rodents maximized novelty signal-to-noise ratio ...
