Abstract:

Unstructured text is exploding at an astounding rate. Managing documents, mining interesting information from text, making decisions based on large volume of text impose a big challenge in this era. One solution is to apply information extraction (IE) techniques, which map unstructured text into structured knowledge representation, and store them into existing databases or knowledge bases. Then we can apply existing data analytics tools based on structured data for diverse purposes. In this talk, I will walk you through the core IE techniques such as named entity recognition, named entity disambiguation, and relation extraction, as well as their real-world applications. I will also cover our ongoing work regarding harvesting domain specific knowledge by using deep learning techniques.

Bio:

Dr. Lizhen Qu is currently a researcher at the Machine Learning Research Group of National ICT Australia (NICTA), a research fellow at Australian National University. He was an invited speaker at Machine Learning Summer School in Sydney in 2015. Prior to being employed at NICTA, Lizhen Qu was a post-doc at Max Planck Institute for Informatics. Dr. Qu completed his PhD doctorate qualification in Sentiment Analysis from Max Planck Institute for Informatics and University of Saarland.  In 2008, he received the Diploma degree from the Computer Science Department at Technical University of Kaiserslautern. His main research focus is in natural language processing (NLP), with particular emphasis on machine learning approaches. He is especially interested in devising deep learning models to extract structured representations of knowledge from unstructured text.

Slides of 10+ excellent tutorials at KDD 2015: Spark, graph mining and many more

by Yanchang Zhao
RDataMining.com

I attended the KDD 2015 conference in Sydney last week. At the conference, there were more than 10 tutorials and I went to two of them, which are 1) Graph-Based User Behavior Modeling: From Prediction to Fraud Detection, and 2) Large Scale Distributed Data Science using Apache Spark. Both tutorials were very popular and the rooms were full, with some audience standing and some sitting on the floor.

The speakers and the conference organizers kindly provided the tutorial slides online at http://www.kdd.org/kdd2015/tutorial.html. I strongly suggest you to have a look at the slides, if you haven’t attended the conference. Below are a list of tutorials at the conference.

– VC-Dimension and Rademacher Averages: From Statistical Learning Theory to Sampling Algorithms
– Graph-Based User Behavior Modeling: From Prediction to Fraud Detection
– A New Look at the System, Algorithm and Theory Foundations of Large-Scale Distributed Machine Learning
– Dense subgraph discovery (DSD)
– Automatic Entity Recognition and Typing from Massive Text Corpora: A Phrase and Network Mining Approach
– Big Data Analytics: Optimization and Randomization
– Big Data Analytics: Social Media Anomaly Detection: Challenges and Solutions
– Diffusion in Social and Information Networks: Problems, Models and Machine Learning Methods
– Medical Mining
– Large Scale Distributed Data Science using Apache Spark
– Data-Driven Product Innovation
– Web Personalization and Recommender Systems

Another good news is, most (if not all) presentations at KDD 2015 have been video recorded, so hopefully the videos will be available at its website soon.

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

• 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
