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’...

To enhance the certainty of the grade block model, it is necessary to increase the number of exploratory drillholes and collect more data from the deposit. The inputs of the process of locating these additional drillholes include the variogram model parameters, locations of the samples taken from the initial drillholes, and the geological block model. The uncertainties of these inputs will lead...

In recent years many corporations have become active on social networking sites (SNS). However, our understanding about how and why community members use corporate pages on SNS has not kept pace. In our study, we test a socio-cognitive model of brand page usage to investigate users’ incentives to consume and interact with corporations on Facebook. In order to do so, we conducted an online surve...

We compared and combined the traditional information retrieval (IR) methods of expert identification with a computational cognitive model to test their effectiveness in facilitating exploratory search performance using a data set from a large-scale social tagging system. We found that the two methods of expert identification, although based on different assumptions, were in general consistent i...

This paper argues that sequences of exploratory drawings constructed by designer’s movements and decisions trace systematic and logical paths from ideas to designs. This argument has three parts. First, sequences of exploratory sketches produced by product designers, against the same task specification, are analyzed in terms of the cognitive categories of reinterpretation, emergence and abstrac...
