SUMMARY:Introducing the Australian Digital Observatory:  Providing Social Media Data and Analytics at Scale for Australian Researchers
DESCRIPTION:Prof. Richard Sinnott1, Mr Luca  Morandini1, Mr Abdul Rehman Mohammad1, Dr Sach Jayasinghe1, Prof Daniel Angus1, Dr Marissa Takahashi1\n1The University Of Melbourne, Melbourne, Australia\n2Queensland Universty of Technology, Brisbane, Australia\nThe Australian Digital Observatory has been funded by ARDC to support large scale access to and use of social media data by Australian researchers. Examples of the social media data of interest include data from platforms such as Twitter, Instagram, Flickr, Foursquare, Reddit, YouTube and e-Gaming platforms such as Steam/Valve. This talk will cover the initial user communities on what they would require from such a platform as well as the technical aspects of development and delivery of a big social data platform tasked with dealing with voluminous amounts of varied social media data. Example case studies will be presented reflecting the initial user/community demands including:\n\nfinding and tracing historic information related to social media use by suicide completers (who committed suicide in 2014/2015);\nthe challenges of dealing with fake news and technical solutions to attempt to identify news as fake based on machine learning algorithms and the diffusion patterns of data;\ngeolocating social media data where the explicit location (lat/long) of posts, i.e. based on the location based service of their mobile device, is not present and the privacy concerns that this gives rise to;\ntopic modelling and sentiment analysis at scale.\n\nThe talk will cover the technical aspects of the platform and use of the National Research Cloud and technologies such as Docker and Notebooks and how they will serve the user communities in their data research requirements, i.e. where their local resources/laptops are insufficient to manage large quantities of data.\n\nBiography:\nProfessor Richard O. Sinnott is Professor of Applied Computing Systems and Director of the Melbourne eResearch Group at the University of Melbourne. He has been lead software engineer/architect on an extensive portfolio of national and international projects, with specific focus on those research domains requiring finer-grained access control (security) and those dealing with big data challenges. He has over 400 peer reviewed publications across a range of applied computing research areas.\n
