AusDM 2015 submission deadline extended to Thursday 30 April

The 13th Australasian Data Mining Conference (AusDM 2015)
Sydney, Australia, 8–9 August 2015 (co-located with SIGKDD’15)
URL: http://ausdm15.ausdm.org/

The Australasian Data Mining Conference has established itself as the premier Australasian meeting for both practitioners and researchers in data mining. It is devoted to the art and science of intelligent analysis of (usually big) data sets for meaningful (and previously unknown) insights. This conference will enable the sharing and learning of research and progress in the local context and new breakthroughs in data mining algorithms and their applications across all industries.

Since AusDM’02 the conference has showcased research in data mining, providing a forum for presenting and discussing the latest research and developments. Since 2006, all proceedings have been printed as volumes in the CRPIT series. Built on this tradition, AusDM’15 will facilitate the cross-disciplinary exchange of ideas, experience and potential research directions. Specifically, the conference seeks to showcase: Research Prototypes; Industry Case Studies; Practical Analytics Technology; and Research Student Projects. AusDM’15 will be a meeting place for pushing forward the frontiers of data mining in academia and industry. AusDM’15 is proud to be co-located with SIGKDD 2015 in Sydney, Australia.

Publication and topics
We are calling for papers, both research and applications, and from both academia and industry, for presentation at the conference.All papers will go through double–blind, peer–review by a panel of international experts. Accepted papers will be published in an up–coming volume (Data Mining and Analytics 2015) of the Conferences in Research and Practice in Information Technology (CRPIT) series by the Australian Computer Society which is also held in full–text on the ACM Digital Library and will also be distributed at the conference. For more details on CRPIT please see http://www.crpit.com. Please note that we require that at least one author for each accepted paper will register for the conference and present their work.

AusDM invites contributions addressing current research in data mining and knowledge discovery as well as experiences, novel applications and future challenges. Topics of interest include, but are not restricted to:

• Applications and Case Studies — Lessons and Experiences
• Big Data Analytics
• Biomedical and Health Data Mining
• Business Analytics
• Computational Aspects of Data Mining
• Data Integration, Matching and Linkage
• Data Mining Education
• Data Mining in Security and Surveillance
• Data Preparation, Cleaning and Preprocessing
• Data Stream Mining
• Evaluation of Results and their Communication
• Implementations of Data Mining in Industry
• Integrating Domain Knowledge
• Link, Tree, Graph, Network and Process Mining
• Multimedia Data Mining
• New Data Mining Algorithms
• Professional Challenges in Data Mining
• Privacy-preserving Data Mining
• Spatial and Temporal Data Mining
• Text Mining
• Visual Analytics
• Web and Social Network Mining

Keynote speakers
As is tradition for AusDM we have lined up an excellent keynote speaker program. Each speaker is a well known research and/or practitioner in data mining and related disciplines. The keynote program provides an opportunity to hear from some of the world’s leaders on what the technology offers and where it is heading.

Submission of papers
We invite two types of submissions for AusDM 2015:
• Academic submissions: Normal academic submissions reporting on research progress, with a paper length of between 8 and 12 pages in CRPIT style, as detailed below. Academic submissions we will use a double-blinded review process, i.e. paper submissions must NOT include authors names or affiliations (and also not acknowledgements referring to funding bodies). Self-citing references should also be removed from the submitted papers (they can be added on after the review) for the double blind reviewing purpose.
• Industry submissions: Submissions from governments and industry can report on specific data mining implementations and experiences. Submissions in this category can be between 4 and 8 pages in CRPIT style, as detailed below. These submissions do not need to be double-blinded. A special committee made of industry representatives will assess industry submissions.

Paper submissions are required to follow the general format specified for papers in the CRPIT series by the Australian Computer Society. Submission details are available from http://crpit.com/AuthorsSubmitting.html. LaTeX styles and Word templates may be found on this site. LaTeX is the recommended typesetting package. The electronic submissions must be in PDF only, and made through the AusDM’15 Submission Page. Note that, to be co-located with SIGKDD, this year’s submission deadline is earlier than usual.

Important Dates
Submission of full papers: Thursday 30 April 2015 (midnight PST)
Notification of authors: Sunday June 7 2015
Final version and author registration: Sunday June 28 2015
Conference: 8–9 August 2015

Seminar of IAPA Canberra Chapter: Big Data in the Social Sciences, Wednesday 29 April

Date: Wednesday 29 April
Time: 5.45pm for a 6pm start
Cost: Nil
Where: SAS Offices, 12 Moore Street, Canberra, ACT 2600
RSVP link: http://www.iapa.org.au/Event/ACTChapterEvent29AprilBigDataInSocialSciences

Join us for our next ACT Chapter Event on the 29th of April. We have guest speaker Robert Ackland presenting on Big Data in the Social Sciences. Robert will share on the challenges, give insight into new opportunities and discuss some of the tools that are available for social science big data research.

More about the event: Social scientists are increasingly using large-scale datasets from the Web (e.g. Twitter, WWW hyperlinks, Facebook etc.) to seek answers to long-standing questions about social, economic and political behaviour. An example was how social media data was used to study social inequality, diurnal and seasonal mood changes and the spread of protest during the Arab Spring. This presentation aims to highlight the methodological challenges and opportunities of big data (in particular, social media data) in empirical social science research.

About Robert Ackland

Robert Ackland is an Associate Professor in the Australian Demographic and Social Research Institute at the Australian National University and leads the Virtual Observatory for the Study of Online Networks (http://voson.anu.edu.au). His PhD was in economics, focusing on index number theory in the context of cross-country comparisons of income and inequality. Robert has been studying online social and organisational networks since 2002 and his research has been funded by five Australian Research Council grants. His research has appeared in journals such as the Review of Economics and Statistics, Social Networks, Computational Economics, Social Science Computer Review, and the Journal of Social Structure. VOSON was established in 2005, and aims to advance the social science of the Internet by conducting research, developing research tools, and providing research training. The VOSON software for hyperlink network construction and analysis has been publicly available since 2006 and has been used by around 2000 researchers worldwide. Robert established the Social Science of the Internet specialisation in the ANU’s Master of Social Research in 2008, and his book Web Social Science: Concepts, Data and Tools for Social Scientists in the Digital Age (SAGE) was published in July 2013. He is CEO of Uberlink Corp (http://www.uberlink.com) which he established to commercialise the VOSON software.

Hadoop and Neo4j

Hadoop is being widely used for processing big data and Neo4j is a popular open-source graph database. When doing social network analysis on big data, a “natural” thought is to use them together. Unfortunately, Neo4j cannot work directly on HDFS or HBase. Is it good to use them together for social network analysis of big data? If yes, any pros/cons and how to do it efficiently? Or shall we try other options, such as Hadoop + Giraph, or Spark + GraphX? Please share your ideas, and all suggestions or experiences will be appreciated. Thanks.

Anyway, to know more about how Neo4j and Hadoop can work together, I came across two presentations below, which might be interested to those who are doing social network analysis of big data.
