398 The more a computer knows about a user, the better it can serve that user. But there are different styles, and even philosophies, of how to teach our computers about us—about our habits, interests, patterns, and preferences. " Cheap " user modeling, the subject of this essay, simply means ascertaining a few bits of information about each user, processing that information quickly, and provid...

Recently, researchers have begun exploring methods of scoring student essays with respect to particular dimensions of quality such as coherence, technical errors, and relevance to prompt, but there is relatively little work on modeling thesis clarity. We present a new annotated corpus and propose a learning-based approach to scoring essays along the thesis clarity dimension. Additionally, in or...

With the innovation of computer technology and the application of the new network technology, many auxiliary network teaching and learning software and programs related to English teaching has emerged. Automated essay scoring system is a revolutionary innovation network system, in recent years, it makes the reform of English essay teaching mode more feasible. Basing on the network automated ess...

This work investigates whether the development of ideas in writing can be captured by graph properties derived from the text. Focusing on student essays, we represent the essay as a graph, and encode a variety of graph properties including PageRank as features for modeling essay scores related to quality of development. We demonstrate that our approach improves on a stateof-the-art system on th...

The dissertation includes three essays. These three empirical studies apply structural equation modeling (SEM) to examine key issues in green supply chain management. The hypothesized model is tested using a sample of supply chain managers derived from a Dun and Bradstreet database. The data collection is through a large webbased survey. The first essay examines how a firm’s proactive environme...

Stress concentration factors have been examined in a functionally graded material (FGM) plate with central holes in different shapes in this essay. The material properties change along the thickness of plate. ABAQUS software has been utilized for modeling of problem in which subroutine of ABAQUS sub-program was used for modeling of the targeted material. The considering shapes for hole in plate...

This essay considers the prospects of modeling spacetime as a phenomenon that emerges in the low-energy limit of a quantum liquid. It evaluates three examples of spacetime analogues in condensed matter systems that have appeared in the recent physics literature, indicating the extent to which they are viable, and considers what they suggest about the nature
