Predicting Operators Fatigue in a Human in the AI Loop for Defect Detection in Manufacturing

Quality inspection, typically performed manually by workers in the past, is now rapidly switching to automated solutions, using artificial intelligence (AI)-driven methods. This elevates the job function of the quality inspection team from the physical inspection tasks to tasks related to managing workflows in synergy with AI agents, for example, interpreting inspection outcomes or labeling inspection image data for the AI models. In this context, we have studied how defect inspection can be enhanced, providing defect hints to the operator to ease defect identification. Furthermore, we developed machine learning models to recognize and predict operators’ fatigue. By doing so, we can proactively take mitigation actions to enhance the workers’ well-being and ensure the highest defect inspection quality standards. We consider such processes to empower human and non-human actors in manufacturing and the sociotechnical production system. The paper first outlines the conceptual approach for integrating the operator in the AI-driven quality inspection process while implementing a fatigue monitoring system to enhance work conditions. Furthermore, it describes how this was implemented by leveraging data and experiments performed for a real-world manufacturing use case

Language processing infrastructure in the XLike project

This paper presents the linguistic analysis tools and its infrastructure developed within the XLike project. The main goal of the implemented tools is to provide a set of functionalities for supporting some of the main objectives of XLike, such as enabling cross-lingual services for publishers, media monitoring or developing new business intelligence applications. The services cover seven major and minor languages: English, German, Spanish, Chinese, Catalan, Slovenian, and Croatian. These analyzers are provided as web services following a lightweight SOA architecture approach, and they are publically callable and are catalogued in META-SHAREPostprint (published version

Human in the AI loop via xAI and Active Learning for Visual Inspection

Industrial revolutions have historically disrupted manufacturing by introducing automation into production. Increasing automation reshapes the role of the human worker. Advances in robotics and artificial intelligence open new frontiers of human-machine collaboration. Such collaboration can be realized considering two sub-fields of artificial intelligence: active learning and explainable artificial intelligence. Active learning aims to devise strategies that help obtain data that allows machine learning algorithms to learn better. On the other hand, explainable artificial intelligence aims to make the machine learning models intelligible to the human person. The present work first describes Industry 5.0, human-machine collaboration, and state-of-the-art regarding quality inspection, emphasizing visual inspection. Then it outlines how human-machine collaboration could be realized and enhanced in visual inspection. Finally, some of the results obtained in the EU H2020 STAR project regarding visual inspection are shared, considering artificial intelligence, human digital twins, and cybersecurity

Improving the Classification of Newsgroup Messages through Social Network Analysis

Newsgroup participants interact with their communities through conversation threads. They may respond to a message to answer a question, debate a topic, support or disagree with another person’s point, or digress and write about a different subject. Understanding the structure of threads and the sentiment of the participants’ interaction is valuable for search and moderation of newsgroups. In this paper, we focus on automatic classification of message replies into several types. For representing messages we consider rich feature sets that combine the standard author reply-to network properties with features derived from four additional structures identified in the data: 1) a network of authors who participate in the same threads, 2) network of authors who post similar content, 3) network of threads sharing common authors, and 4) network of content-related threads. For selected newsgroups we train linear SVM classifiers to identify agreement and disagreement with the original message, and question and answer patterns in the threads. We show that the use of newly defined features substantially improves classification of messages in comparison with the SVM model based only on the standard reply-to network

OntoGen: Semi-automatic Ontology Editor

In this paper we present a semi-automatic ontology editor as implemented in a new version of OntoGen system. The system integrates machine learning and text mining algorithms into an efficient user interface lowering the entry barrier for users who are not professional ontology engineers. The main features of the systems include unsupervised and supervised methods for concept suggestion and concept naming, as well as ontology and concept visualization. The system was tested in extensive user trails and in several realworld scenarios with very positive results
