relationship with the potential to mutually enhance their capabilities ml can play a pivotal role in the construction of kgs by automating ontology design inferring classes and relations from alternative sources and aiding data curators in making informed decisions ml algorithms need data to be in a certain form meaning that they need to get the data prepared and ensure high quality data used as input poor quality datasets can compromise ml systems in several ways the four data quality categories of intrinsic contextual representational and accessibility are relevant to different stages of the ml development pipeline for example intrinsic data quality categories include accuracy completeness and consistency while contextual data quality categories include bias relevance and validity conversely kgs can enrich ml models through node or graph embedding techniques link prediction supporting explainability and improving the overall performance of data driven models low quality kgs i e those not fit to be used may lead to biased or inaccurate ml models hindering their ability to generate meaningful insights or make informed decisions the growing range of ml data management guidelines frameworks and standards presents practitioners with a vast range of possible criteria to aspire to on top of the traditional data management practices that were established in previous decades this workshop aims to explore the intricate interplay of data quality ml and kgs elucidating limitations in assessment methodologies proposing effective methods for objective quality assessment and addressing challenges on ml and ai in general verify if and to what extent well known quality metrics are compliant with ml based quality assessment and addressing fair principles we also welcome proposals riding the path of explainable ai large language models generative ai and any ai driven approach that can be applied to the semantic web technologies to support and enhance data quality assessment and improvement topics of interest new approaches for performing data quality assessment or improvement of knowledge graphs via machine learning quality assessment over the time

for the open data institute odi she is a fellow of the british computer society and the royal society of arts and a hans fischer senior fellow elena s work is at the intersection between ai and social computing she features in the top 100 most influential scholars in knowledge engineering of the last decade and in the women in ai 2000 ranking she is the president of the semantic web sciences association title when stars align studies in data quality knowledge graphs and machine learning abstract in this talk i will present several projects that tease out the intricate relationship between these three fields of research to produce better ai datasets and with that better ai models and downstream applications i will start with work in knowledge graphs which are machine readable structured data representations organised for general purpose use besides data integration they are extensively used in search engines recommender systems virtual assistants and other ai contexts commonly as a source of domain knowledge and explanations i propose sociotechnical methods drawing on machine learning and other techniques to understand biases improve the quality and increase people s trust in knowledge graphs then i will move to ongoing work on assuring any type of ai dataset using semantic technologies i will introduce the data centric ai programme at the open data institute and deep dive into croissant a schema org based vocabulary to describe ai datasets to improve their quality and reuse slides slides are available online at the following link 10 05 10 30 am stefani tsaneva stefan
