Understanding the Visual Aesthetics of Mobile Apps in Everyday Life: The Influence Cute Aesthetics

This paper investigates visual aesthetics (VA) of mobile apps’ in everyday life by examining the effects of affect and cute aesthetics. We analyzed two theoretical dimensions of affect, positive affect (PA) and negative affect (NA), and provided an analysis of the relevance of PA and NA by relating them to VA of three interface designs (ID) with varying levels of cute aesthetics (i.e. low, mid and high). Data was collected using a survey. Regression results from 166 participants suggest that cute aesthetics invoke PA (i.e., interested, excited, enthusiastic) and that it is a strong positive predictor for VA across all three IDs. This study contributes to a better understanding of the relevance of positive affect and cute aesthetics on visual aesthetics of mobile apps in everyday life

Graph-based Cluster Analysis to Identify Similar Questions: A Design Science Approach

Social question answering (SQA) services allow users to clarify their queries by asking questions and obtaining answers from other users. To enhance the responsiveness of such services, one can identify similar questions and, thereafter, return the answers available. However, identifying similar questions is difficult because of the complex language structure of user-generated questions. For this reason, we developed an approach to cluster similar questions based on a web of social relationships among the questions, the answers, the askers, and the answerers. To do so, we designed a graph-based cluster analysis using design science research guidelines. In evaluating the results, we found that the proposed graph-based cluster analysis is more promising than baseline methods

On assigning place names to geography related web pages

In this paper, we attempt to give spatial semantics to web pages by assigning them place names. The entire assignment task is divided into three sub-problems, namely place name extraction, place name disambiguation and place name assignment. We propose our approaches to address these sub-problems. In particular, we have modified GATE, a wellknown named entity extraction software, to perform place name extraction using a US Census gazetteer. A rule-based place name disambiguation method and a place name assignment method capable of assigning place names to web page segments have also been proposed. We have evaluated our proposed disambiguation and assignment methods on a web page collection referenced by the DLESE metadata collection. The results returned by our methods are compared with manually disambiguated place names and place name assignment. It is shown that our proposed place name disambiguation method works well for geo/geo ambiguities. The preliminary results of our place name assignment method indicate promising results given the existence of geo/non-geo ambiguities among place names.Published versio

Aesthetic Experience and Acceptance of Human Computation Games

Human computation games (HCGs) are applications that leverage games to solve computational problems that are out reach of the capacity of computers. Game aesthetics are critical for HCG acceptance, and the game elements should motivate users to contribute time and effort. In this paper, we examine the effect of aesthetic experience on intention to use HCGs. A between-subjects experiment was conducted to compare a HCG and a human computation system (HCS). Results demonstrated that HCGs provided a greater sense of aesthetic experience and attracted more intentional usage than HCSs. Implications of this study are discussed.Accepted versio

A digital library for geography examination resources

We describe a Web-based application developed above a digital library of geographical resources for Singapore students preparing to take a national examination in geography. The application provides an interactive, non-sequential approach to learning that supplements textbooks.Published versio
