This article presents an exploratory research study about the influence of word clouds on critical thinking when they are incorporated into online discussions. In an online discussion, students were asked to critically analyze two speeches, being assigned to one of two conditions: one in which the text was linear, and one in which the text was presented in the form of word clouds. Discussions p...

We study a geometric representation problem, where we are given a set B of axis-aligned rectangles (boxes) with fixed dimensions and a graph with vertex set B. The task is to place the rectangles without overlap such that two rectangles touch if the graph contains an edge between them. We call this problem CONTACT REPRESENTATION OF WORD NETWORKS (CROWN). It formalizes the geometric problem behi...

Mobile Cloud Computing has brought the IT industry to a new level by providing an innovative technique with the help of which one can access anything, anytime from anywhere. It is an industry buzz word since 2009 and a relatively new concept that combines cloud computing, mobile computing and wireless networking. This technology has uplifted the usability experience of mobile users. Over the pa...

Recent trend of mobile computing is emerging toward executing resource-intensive applications in mobile devices regardless of underlying resource restrictions (e.g. limited processor and energy) that necessitate imminent technologies. Prosperity of cloud computing in stationary computers breeds Mobile Cloud Computing (MCC) technology that aims to augment computing and storage capabilities of mo...

Office software suite is one of the most widely used and well developed applications. The suite includes word processor, spreadsheet, presentation, and so on. With recent developments of high-speed network and distributed computing technologies, some office applications such as document processing, have turned web-based (e.g., Microsoft Office WAC) and even cloud-based (e.g., Google Docs). The ...

This study investigated the effects of word imageability and orthographic neighbourhood size, as well their combined effects, in free recall recognition memory. A total 45 young adults performed tasks on same materials. Word size were orthogonally manipulated across four conditions: low-imageability words – high N, saveur [flavor], low [total], high-imageability carré [square] nuage [cloud]. Th...

Many word clouds provide no semantics to the word placement, but use a random layout optimized solely for aesthetic purposes. We propose a novel approach to model word signi cance and word a nity within a document, and in comparison to a large background corpus. We demonstrate its usefulness for generating more meaningful word clouds as a visual summary of a given document. We then select keywo...
