Search engines rely heavily on term-based approaches that represent queries and documents as bags of words. Text---a document or a query---is represented by a bag of its words that ignores grammar and word order, but retains word frequency counts.

This poster summarizes the methodology and results from an experiment to collect terms used by subjects in the verbal description of images from the domains of abstract art, satellite imagery and photo-microscopy. The resulting natural language vocabulary was then analyzed to identify a set of concepts that were shared across subjects. These concepts were subsequently organized as a faceted voc...

This meta-analysis examines the effects of vocabulary interventions on pre-K and kindergarten children’s oral language development. The authors quantitatively reviewed 67 studies and 216 effect sizes to better understand the impact of training on word learning. Results indicated an overall effect size of .88, demonstrating, on average, a gain of nearly one standard deviation on vocabulary measu...

One of the critical issues determining the successful development of information systems is what might be described as the communication gap between the user group and the IS development group that occurs during the system analysis phase. This gap, we contend, stems from the lack of understanding of one another’s domain knowledge without for example, a common vocabulary it is difficult to excha...
