? DSL's latest research outcomes on mining social norms from open source communities have been presented at the 24th European Conference on Information Systems and 13th International Conference on Mining Software Repositories. The project is led by PhD student Daniel Avery, Dr. Hoa Dam and Prof. Aditya Ghose, and involves collaboration with University of Otago's researchers.
Prof. Aditya Ghose has been invited to deliver a 2-week course on "Computational Service Science" as part of the Prime Minister of India's key educational project, GIAN, under which under which foreign scholars teach at India's leading technology institutes to build knowledge and transform higher education across the country.
DSL authors Renuka Sindhgatta (also of IBM Research India), Prof. Aditya Ghose and Dr. Hoa Dam will report on a novel framework that uses data analytics for optimal business process provisioning at the 2016 International Conference on Advanced Information Systems Engineering (CAISE), the premier conference in this area (acceptance rate: 16.5%)
Prof. Aditya Ghose, Prof. Andrew Miller and Dr. David Stirling were among the authors of a submission (with Prof. David Thwaites of the University of Sydney as lead author) entitled "Mining routine radiation oncology clinical datasets within a distributed rapid learning framework: the potential for supporting optimised clinical decisions" that won the Best Abstract Award at the Cancer Institute of NSW Innovations in Cancer Treatment and Care Conference 2014.
Prof. John Mylopoulos, eminent software engineering and conceptual modelling researcher, is currently visiting the Decision Systems Lab for a period of 3 weeks. His visit was preceded by a visit by Prof. Akhil Kumar from Penn State University in early January.
The Decision Systems Lab/Centre for Oncology Informatics has initiated a new collaboration with the Liverpool Hospital on radiation oncology decision support, funded by a $114,000 research contract.
Prof. Aditya Ghose presented a keynote at a plenary session of Int'l Conf. on Service-Oriented Computing Workshops on Nov. 16th, 2015 in Goa, India.
Prof. Aditya Ghose has been invited to deliver a keynote at a joint plenary session of the Service-Oriented Enterprise Architecture and Evolutionary Business Process Workshops at the EDOC-2015 conference (Adelaide, September, 2015). His keynote title: "The post-theoretic enterprise: Data-driven evolution of enterprise functionality".

TITLE: Predicting Database Workloads through Mining Periodic Patterns in Database Audit Trails
Abstract: Information about the periodic changes of intensity and structure of database workloads plays an important role in performance tuning of functional components of database systems. Discovering the patterns in workload information such as audit trails, traces of user applications, sequences of dynamic performance views, process logs, etc. is a complex and time consuming task. In the presentation we shall investigate a new approach to analysis of information included in the database audit trails. In particular, we shall present how to transform information included in the audit trails into a format that can be used for discovering the periodic patterns in the fluctuations of database workloads. We shall present few models of periodic patterns and the algorithms for discovering periodic patterns in audit trails. We shall also present a collection of rules that can be used to derive complex periodic patterns from the elementary and other complex patterns and and we shall show how to use such rules to predict the future workload levels.
