This is a nine month progress report detailing my research into supporting users in their search for information, where the questions, results or even their environment requires functionality beyond the scope of keyword search alone. While keyword search environments, such as Google, have become the familiar standard for search on the web, research has shown that users, who may not know which k...

Tripleset interlinking is one of the main principles of Linked Data. However, the discovery of existing triplesets relevant to be linked with a new tripleset is a non-trivial task in the publishing process. Without prior knowledge about the entire Web of Data, a data publisher must perform an exploratory search, which demands substantial effort and may become impracticable, with the growth and ...

This article investigates the effect of compositions of managerial characteristics of top management team on the extent of information technology (IT) adoption. Adopting the upper echelon theory as theoretic foundation, the study formulated hypotheses relating compositions of top management team (TMT) characteristics to the extent of IT adoption in small businesses. Specifically, the TMT charac...

Recent increase in digitalization and archiving efforts on news data have led to overwhelming amount of online information for a general user, thus making it difficult for them to retrospect on past events. One dimension along which past events can be effectively organized is time. Motivated by this idea, we introduce EXPOSÉ, an exploratory search system that explicitly uses temporal informatio...

No significant body of research examines writing achievement and the specific skills and knowledge in the writing domain for postsecondary (college) students in the U.S., even though many at-risk students lack the prerequisite writing skills required to persist in their education. This paper addresses this gap through a novel exploratory study examining how automated writing evaluation (AWE) ca...

Hand-drawn sketching on napkins or whiteboards is a common, accessible method for generating visual representations. This practice is shared by experts and non-experts and is probably one of the faster and more expressive ways to draft a visual representation of data. In order to better understand the types of and variations in what people produce when sketching data, we conducted a qualitative...

We investigate questions of how to reason about learner meaning in cases where the set of correct meanings is never entirely complete, specifically for the case of picture description tasks (PDTs). To operationalize this, we explore different models of representing and scoring non-native speaker (NNS) responses to a picture, including bags of dependencies, automatically determining the relevant...

Introduction. This study explores blind users' unique help­seeking situations in interacting with digital libraries. In particular, help­seeking situations were investigated at both the physical and cognitive levels. Method. Fifteen blind participants performed three search tasks, including known­ item search, specific information search, and exploratory search, using the selected digital libra...
