Summarizing audit trails in the Aeolus security platform
… is an auditing subsystem that maintains a log in which it stores information about every security related event that occurs while applications run. The log allows later analysis to determine whether the security policies of the application have been followed. For an Aeolus user, analyzing …

An Integrated Cyber Threat Hunting Program Applying Machine Learning for Enhanced Intelligence Capabilities
This project entails the creation of a simplified event log filterer that can be used by new threat hunters to the field of threat intelligence. The event log filterer employs three filtering options that allow the threat hunter to analyse application, system, security and Sysmon logs, which are …

Matching events and activities
… by IT services that produce massive amounts of event data during process execution. Aiming at a better process understanding and improvement, this event data can be used to analyze processes using process mining techniques. Process models can be automatically discovered and the execution can be …

META LEARNING IN PROCESS MINING: TOWARD A SYSTEMATIC APPROACH TO DESIGN DATA ANALYTICS PIPELINES WITH EVENT LOGS
… performed within their business processes. The event data describes the actual process performance along with several possible attributes. Process mining stands as a set of techniques that leverage insights from event data. With that, organizations can employ process mining-based approaches to …

The performance of information systems implementation outcomes: the case of an enterprise system implementation in a South African University
… approach which downplays the information technology (IT) system in focus and views outcomes as static and fixed. Purpose of the study: The main purpose of this study was to provide understanding on how the realities of IS success and failure are performed within an organisation. This was …

Visualisation of Mental Health Community Service Patient Pathways
… a dataset provided by project partners, an event log was created and analysed for quality and completeness. Several adaptations of clustering algorithms, including Hierarchical Agglomerative Clustering (HAC), DBSCAN, and K-Medoids, were applied to both vectorial and syntactical …

Towards Process Mining with Natural Language Event Logs
… concerned with extracting knowledge from process event logs, enabling analysis and improvement of business processes. Common use cases include process discovery, where process flow models are generated; conformance checking, where actual processes are compared against prescribed models; and …

An Online Learning Platform for English as a second language for young deaf Indian Sign Language users: usage patterns and user engagement
… learning (Kitade, 2000). A statistical study of event log data drawn from the ELP3 and a questionnaire is used here to generate an understanding of how the online platform is used by a group of deaf learners and indicates that they generally like the ELP3 with some preference for certain …

Corrective Evolution of Adaptable Process Models
… model may later need to be updated based on the logs of adapted process instances. Evolving the process model is necessary if adapting at run-time is too costly, or if certain adaptations fail and should be avoided. An issue that is insufficiently addressed in the previous work on process …

Mining intrusion detection alert logs to minimise false positives & gain attack insight
Utilising Intrusion Detection System (IDS) logs in security event analysis is crucial in the process of assessing, measuring and understanding the security state of a computer network, often defined by its current exposure and resilience to network attacks. Thus, the study of understanding network …

Enhancement of the Real-Time Dose Tracking System for Interventional Fluoroscopic Procedures through Monte Carlo Investigations
… can be routinely calculated using exposure event log files. Effective dose and most organ doses calculated with PCXMC closely match those calculated with EGSnrc. Data grouping, which can be done automatically, makes the calculation time with PCXMC on a standard PC acceptable. The method we …
