Information and Data Quality for Intelligent Systems


Data quality (DQ) is critical to successfully implementing artificial intelligence (AI) systems. However, both AI researchers and practitioners overwhelmingly concentrate on models/algorithms while undervaluing the impact of DQ (Sambasivan et al., 2020). The trend of AI research is moving from model-centric AI towards data-centric AI (Ng, 2021). In the year 2021 alone, 108,000 journal and conference articles have been published on DQ in AI and closely-related areas in total. The demand for DQ assurance in high-stakes domains such as medical, legal, and cyber-security is more intensive and urgent (Sambasivan et al., 2020). Recently, techniques such as semi-supervised learning (SSL), transfer learning (TL), few-shot learning (FSL), active learning (AL), and generative adversarial learning (GAN) have been proposed by natural language processing (NLP) and machine learning (ML) researchers to enhance the model performance when the quality of training data is not high enough or the amount of the data is not sufficient (Lourentzou, 2019). However, the data quality assessment, assurance, and improvement covering the whole life-cycle of building an intelligent system have not yet been well-investigated (Chen et al., 2021). 

This special issue aims to bring AI and information science researchers together to understand the challenges, investigate the problems, propose solutions, exchange ideas, share resources, and look for new research directions in the field of DQIS. This special issue focuses on how to use state-of-the-art (SOTA) technologies on assessment, assurance, and improvement of big data for building high-quality intelligent systems. Big data are harvested for building intelligent systems for supporting a broad array of applications from biomedicine, healthcare, education, legal intelligence to smart city and autopilot (Roh et al, 2021). DQ could significantly impact the quality of the intelligent system that is built on it.  The special issue endeavors to publish research and practice on the evaluation and improvement of DQ quantitatively and systematically in specific applications and domains and the roles and best practices of different ML and deep learning (DL) techniques for DQ improvement.
