October 2014:

The DKE group has 7 papers (so far!) accepted by ICDE 2015! What a fantastic achievement! This is certainly a record for DKE and possibly also a record for any database group. Included in the accepted publications are two papers led by people from DKE's sister group in Soochow University - a new group established by Prof Xiaofang Zhou only one year ago.

DKE Alumni, Dr Wasim Sadiq, has been featured as a "research leader" in Discovery at UQ - p.52. [This publication showcases many of UQ's outstanding research activities during the year.] in this profile, Dr Sadiq, currently Vice-President of Strategic Customer Engagement at SAP (one of the largest software companies in the world), comments on the importance in a research career of industry engagement from the time of undertaking a PhD. He also cautions research students not to focus on the end goal so much that they forget to appreciate the experiences along the way. “Doing a PhD is one opportunity in your life where you get to work on a complex problem for a few years on your own with some advice from your supervisor and peers. Sometimes, submitting the final PhD dissertation to get the degree becomes the key objective. My advice is not to make this the only goal. That will happen in any case if you do the right things. The experiences and lessons you will learn during your PhD are going to be the key asset in your professional life afterwards. Completing a PhD helps you gain valuable problem-solving skills by looking at problems in a multi-faceted way. It also helps you learn how to handle constructive criticism and most importantly, to not give up.”

September 2014:

Congratulations to Dr Helen Huang who has won the "Infotech Research" Award at the recent Women in Technology awards (WiT). Helen was selected as the winner for “her contribution to the field of IT research, her commitment to ongoing research and her ability and drive to guide the young minds of the future”. The WiT Awards are a fantastic recognition of women in ICT and honour the achievements of women at all levels working within the technology sector.  The awards are now in their 17th year and celebrate the important contribution women make to the technology industry and provide a means for encouraging more women to embark on a career in this sector.  Read more.

April 2014:

DKE researchers, Zhongwen Xu and Dr Yi Yang, along with Ashraf Kassim and Shuicheng Yan from the National University of Singapore, have achieved first place in the MSR-Bing Image Retrieval Challenge organized by Microsoft Research and Microsoft Bing.

This year the grand challenge is in conjunction with the IEEE International conference on multimedia and Expo. The topic of the Challenge is web image retrieval. The contestants are asked to develop systems to assess the effectiveness of query terms in describing the images crawled from the web for image search purposes. A contesting system is asked to produce a floating-point score on each image-query pair that reflects how relevant the query could be used to describe the given image, with higher numbers indicating higher relevance. The dynamic range of the scores does not play a significant role so long as, for any query, sorting by its corresponding scores for all its associated images gives the best retrieval ranking for these images. Click here for details of the contest.

November 2013:

In 2013, The University of Queensland defined its top 30 Research Strengths. The DKE group is excited to announce that "Information Systems and Data Management" has been officially recognised as one of the university's top-30 research strengths.

July 2013:

Professor Maria Orlowska visited the University to receive her Doctor of Science honoris causa on 19 July. She was also the special guest at DKE's Big Data and Real Time Analytics Workshop held in the DKE Lab on 18 July. During her tenure at UQ (1987-2007), Maria made profound contributions to the growth, visibility and quality of the Department of Computer Science, and later School of Information Technology and Electrical Engineering (ITEE). From 1995 to 2007 she headed the school's Data and Knowledge Engineering Research Division. Maria served as a board member on the Australian Research Council, Trustee of the Very Large Database Endowment, and Fellow of the Australian Academy of Science. However, her greatest impact can be felt through her students, many of whom hold positions of leadership in academia and industry both in Australia and overseas. Since leaving UQ, Maria has been serving as the Secretary of State at the Ministry of Science and Higher Education, Poland.

June 2013:

DKE students Xin Zhao and Xiaofeng Zhu (now a post-doc at the University of North Carolina at Chapel Hill) have two full papers accepted by the top multimedia conference, ACM Multimedia 2013. This year the conference accepted 47 full papers only, with <20% acceptance rate. Importantly, Xin’s paper was also selected as one of the best paper candidates. Given the DKE group's high quality of publications at this conference, as well as our group's international standing in this field, we have won the bid to host ACM Multimedia 2015 in Brisbane.

SIGMOD is the best publication venue in database research and one of the best in computer science research. It is particularly tough this year as it used a two-phase double-blind review process. The DKE research group is excited to announce that it has two papers accepted! What a fantastic achievement! Two of the authors, Jingkuan Song and Han Su, are final-year and second-year PhD students, respectively, while another contributor, Jiamin Huang from Nanjing University China, participated in this work during his time as an intern in DKE. Congratulations to all the authors!
