To Succeed, Find a Career Partner

Super-partnerships exist between scholars connected within densely-knit collaboration networks. Understanding how such relationships affect scholars’ careers is of great importance. In this paper, focusing on the longitudinal aspects of scientific collaboration, we analyze collaboration profiles from the egocentric perspective and use analytic extreme value thresholds to identify super-partners. We explore the characteristics of super-partners and the added value of a long-term commitment, which provides quantitative insights into the effect on scientific collaboration associated with close collaboration.

Seven Ways That Data Science Projects Fail

The pragmatic value of data science for solving business problems has made it a rival or replacement for information science from an industry perspective. I reviewed numerous data science projects and interviewed numerous data science experts to understand the factors that make projects successful, but this work also revealed—by counterfactual reasoning and some confessions from the experts—why some data science projects fail. I identified seven causes of failure and I explain here how “information science thinking” can prevent or lessen these problems in data science projects.

Unifying Telescope and Microscope: A Multi-lens Framework with Open Data for Modeling Emerging Events

When investigating a phenomenon or an event, we think choosing a data source can be seen as choosing a lens for observations in physical sciences; a telescope and a microscope both allow us to observe, but two very different worlds.
