Special Issue Information

Dear Colleagues,

System simulation and modeling (SSM) focus on solving problems through the use of models and simulations. SSM is used in almost every science and engineering involving a multidisciplinary nature. SSM develops frameworks that are applicable across disciplines and develop benchmark tools that are useful in developing IoT data processing applications. Modeling theories need to be transformed into consistent frameworks, which in turn are implemented into consistent benchmarks. The world is clearly in the era of internet data processing (e.g., Internet of Things). The challenge for IoT data processing systems is balancing operation and cost tradeoffs by optimizing configuration at both the IoT hardware and software layers to accommodate users’ constraints. For example, several internet data processing application developers and researchers can perform tests in a controllable and repeatable manner. Propelled by the need to analyze the performance of different IoT data processing and Industry 4.0 frameworks, researchers have introduced several IoT simulation and modeling benchmarks. Despite the substantial progress achieved, however, the research community still needs a holistic comprehensive simulation and modeling platforms for IoT data processing. This Special Issue aspires to furnish a compendium of high-quality research articles on the following specific areas of interest, including but not limited to:

Theoretical aspects of modeling and simulation, including formal modeling, model-checking, sensitivity analysis, Monte Carlo methods, variance reduction techniques, experimental design, meta-modeling, methods and algorithms for validation and verification, and selection and comparison procedures;
Development of discrete event simulation benchmarks to evaluate workloads in heterogeneous state-of-the-art hardware platforms;
Advances in modeling and simulation tools for performance evaluation, security problems, and scalable IoT data processing environments;
Cognitive combined discrete and continuous simulations based on both IoT hardware and software;
Cognitive interactive modeling for internet data processing;
Methodology and requirements of benchmarking IoT data processing and Industry 4.0;
Data-driven cognitive computing for industrial IoT;
Advances in Industry 4.0 frameworks and benchmarks for large-scale data analytics;
IoT data processing frameworks for industrial predictive analytics.

Abstract

The data management process is characterised by a set of tasks where data quality management (DQM) is one of the core components. Data quality, however, is a multidimensional concept, where the nature of the data quality issues is very diverse. One of the most widely anticipated data quality challenges, which becomes particularly vital when data come from multiple data sources which is a typical situation in the current data-driven world, is duplicates or non-uniqueness. Even more, duplicates were recognised to be one of the key domain-specific data quality dimensions in the context of the Internet of Things (IoT) application domains, where smart grids and health dominate most. Duplicate data lead to inaccurate analyses, leading to wrong decisions, negatively affect data-driven and/or data processing activities such as the development of models, forecasts, simulations, have a negative impact on customer service, risk and crisis management, service personalisation in terms of both their accuracy and trustworthiness, decrease user adoption and satisfaction, etc. The process of determination and elimination of duplicates is known as deduplication, while the process of finding duplicates in one or more databases that refer to the same entities is known as Record Linkage. To find the duplicates, the data sets are compared with each other using similarity functions that are usually used to compare two input strings to find similarities between them, which requires quadratic time complexity. To defuse the quadratic complexity of the problem, especially in large data sources, record linkage methods, such as blocking and sorted neighbourhood, are used. In this paper, we propose a six-step record linkage deduplication framework. The operation of the framework is demonstrated on a simplified example of research data artifacts, such as publications, research projects and others of the real-world research institution representing Research Information Systems (RIS) domain. To make the proposed framework usable we integrated it into a tool that is already used in practice, by developing a prototype of an extension for the well-known DataCleaner. The framework detects and visualises duplicates thereby identifying and providing the user with identified redundancies in a user-friendly manner allowing their further elimination. By removing the redundancies, the quality of the data is improved therefore improving analyses and decision-making. This study makes a call for other researchers to take a step towards the “golden record” that can be achieved when all data quality issues are recognised and resolved, thus moving towards absolute data quality.
