title: Efficient Process Model Discovery Using Maximal Pattern Mining

authors: Liesaputra, Veronica

subjects: Science & Technology

abstract: In recent years, process mining has become one of the most important and promising areas of research in the field of business process management as it helps businesses understand, analyze, and improve their business processes. In particular, several proposed techniques and algorithms have been proposed to discover and construct process models from workflow execution logs (i.e., event logs). With the existing techniques, mined models can be built based on analyzing the relationship between any two events seen in event logs. Being restricted by that, they can only handle special cases of routing constructs and often produce unsound models that do not cover all of the traces seen in the log. In this paper, we propose a novel technique for process discovery using Maximal Pattern Mining (MPM) where we construct patterns based on the whole sequence of events seen on the traces—ensuring the soundness of the mined models. Our MPM technique can handle loops (of any length), duplicate tasks, non-free choice constructs, and long distance dependencies. Our evaluation shows that it consistently achieves better precision, replay fitness and efficiency than the existing techniques.

title: Do the right thing: Why we require sustainable business reports and what you can do about it.

authors: Martin, Kelly

subjects: corporation reports

abstract: The article focuses on the international initiatives that urge the use of sustainability business reports by organisations particularly corporations. It says that the United Nations (UN) joined with Ceres to create a Global Reporting Initiative (GRI) organisation that will help organisations use their sustainability performance information in reporting. It adds that the Accounting for Sustainability Forum (A4S) partnered with GRI to create the International Integrated Reporting Committee (IIRC).

title: How usable is a smartphone with a Māori-language interface?

authors: Mato, Paora James

subjects: Mäori

abstract: Major languages dominate contemporary technologies. For Mäori, there is opportunity to engage with some technologies using their language and to participate within Mäori- language communities in various digital media. A smartphone launched by Two Degrees Mobile Limited provides a Mäori- language interface option. An initial pilot study indicated users will engage with this interface, but when pushed for time will switch the interface to the English- language option. This paper reports on a study undertaken to test the usability of the smartphone Mäorilanguage interface. Participants reported diffi culties and some frustration as they struggled with new words and unfamiliar uses of words. They also expressed disappointment at poor translations and arbitrary truncations. The feedback highlights perceived shortcomings encountered when technologies that are normally developed and used in a major language are translated for use in minority Indigenous languages. Mäori-language strategies that consider using translated application interfaces should be cognisant of such issues.
