Abstract

1.Prof. Ee-Peng LimTitle: Multimodal Sensemaking using Social Media Data:As social media becomes an integral part of daily lives, it captures interesting user generated content and behaviour data that can be sensed and analysed. While social media companies use the insights learnt from such data to improve their user interface and experience, there are many other interesting insights that help us improve urban environment and public services. Social media data also offers a cheap and scalable approach to perform sensemaking on the urban environment. In this talk, we will showcase a few ongoing research projects in the Living Analytics Research Centre (LARC) which focus on multimodal sensemaking using social media data. The talk will share some new machine learning methods and systems to profile users, locations, and public transportation services. The reasonably good accuracy of these methods also allow them to be deployed in urban application solutions.Biography:Ee-Peng Lim is a professor at the School of Information Systems of Singapore Management University (SMU). He received Ph.D. from the University of Minnesota, Minneapolis. His research interests include social network and web mining, information integration, and digital libraries. He is the co-Director of the Living Analytics Research Center (LARC) jointly established by SMU and Carnegie Mellon University. He is currently an Associate Editor of the ACM Transactions on Information Systems (TOIS),ACM Transactions on the Web (TWeb), IEEE Transactions on Knowledge and Data Engineering (TKDE), Information Processing and Management (IPM), Social Network Analysis and Mining, Journal of Web Engineering (JWE), IEEE Intelligent Systems, International Journal of Digital Libraries (IJDL) and International Journal of Data Warehousing and Mining (IJDWM). He was a member of the ACM Publications Board until December 2012. He serves on the Steering Committee of the International Conference on Asian Digital Libraries (ICADL), Pacific Asia Conference on Knowledge Discovery and Data Mining (PAKDD), and International Conference on Social Informatics (Socinfo).2.Prof. T.C. ChangTitle: Critical Tourism Studies in Asia: Issues and Questions:When King and Porananond (2014: 6) first used the phrase “[to] Asianise the field” in their edited book Rethinking Asian Tourism: Cultures, Encounters and Local Response, they were encouraging greater indigenous scholarship in Asian tourism studies. It is their belief that Asian scholars working in and on Asia bring useful insights and unique perspectives that might differ from non-Asian research, thereby creating more holistic understandings of the world. Such an Asian-centric scholarly inclination has bloomed particularly in the 2000s following increasing numbers of Asians on tour, greater intra- and domestic-tourism within Asia, and the opening of new travel destinations throughout the continent. Around the same time as this surge in Asian tourists and indigenous tourism scholarship is an increasing attention paid to ‘Critical Tourism Studies’ (CTS). The basic premise of CTS is the application of social-cultural theory in tourism analyses, the acknowledgement of researcher bias, and a challenge to mainstream knowledge through a focus on the ‘Other’ (which might include the marginalised, oppressed and the indigenous among other interest groups). In this presentation, I will consider the ‘global’ scope of CTS and the ‘local’ field of Asian tourism knowledge in three ways. Firstly, we will examine what is critical about CTS and how it has evolved over time. Secondly the implications of CTS for Asian tourism research will be explored, and finally issues and questions surrounding critical Asian tourism scholarship will be surfaced. It is the aim of this talk to envision the full potential of CTS if the breadth and depth of ‘local/Asian’ tourism knowledge is brought to bear on its ‘global/lofty’ research agenda.Biography:T.C. Chang is an Associate Professor at the Department of Geography, National University of Singapore (NUS). He was also Assistant and Vice Dean of the Faculty of Arts and Social Sciences (NUS) from 2008 till 2015. He is the co-editor of two books on Asian tourism: Interconnected Worlds: Tourism in Southeast Asia (with Peggy Teo and K.C. Ho; Elsevier, Oxford) and Asia On Tour: Exploring the Rise of Asian Tourism (with Tim Winter and Peggy Teo; Routledge, London and New York). His research interests include Asian tourism knowledge; urban tourism and urban development issues; arts, culture and creativity.3.Dr Kao CaiTitle: An Innovative Model for Municipal Solid Waste Collection Routing in Singapore: To collect and dispose growing amounts of municipal solid waste (MSW) changed to be a hot topic along with the rapid urbanization in past decades. Cities are more and more dependent on the incineration instead of landfilling due to the cost-efficiency and environmental concerns. Considering the limited number of incineration plants and complicated situation of transportation in both spatial and temporal dimensions in different cities, the optimal routing for waste collection turns to be meaningful research topic. In this research, the ant colony optimization (ACO)-based multi-objective routing model coupled with min-max model and Dijkstra's algorithm is proposed to address the question of which route to take from these waste-generating points to the target incineration plant(s) considering travel time, accident probability (black spots), and population exposure, so as to support the routing decision-making. The model is successfully implemented in Singapore and the effectiveness of the model has also been justified. Besides, few limitations of this research have also been discussed, some of which would also be the future directions of our research, especially the design and integration of a web-based routing decision-making support system.Short Bio:Dr. Kai Cao holds a Ph.D. degree in Geography from the Chinese University of Hong Kong in Hong Kong and obtained his B.S. and M.Phil. degrees in Geography from Nanjing University in China. Prior to joining Department of Geography at NUS, he had also worked in Center for Geographic Analysis at Harvard University, Department of Geography at University of Illinois at Urbana-Champaign, and World History Center at University of Pittsburgh respectively. His current research interests center on GIScience and its applications, especially on the topics of spatial simulation and optimization, cyberinfrastructure and geocomputation, land use planning support and urban mobility.4.Prof. Ida Ayu Dwi GiriantariTitle: Renewable Energy Deployment in Indonesia; opportunity and challengeShort Bio:Ida Ayu Dwi Giriantari is Professor in Electrical Engineering Udayana University.
