Since the COVID-19 pandemic, educational institutions have embarked on digital transformation projects. The success of these projects depends on integrating new technologies and understanding the needs of digitally literate students. The “learning by doing” approach suggests that real success in learning new skills is achieved when students can try out and practise these skills. In this article, we demonstrate how Large Language Models (LLMs) can enhance the quality of teaching by using ChatGPT in a role-playing simulation game scenario to promote active learning. Moreover, we discuss how LLMs can boost students’ interest in learning by allowing them to practice real-life scenarios using ChatGPT.

The following article deals with the implementation of a Learning Assistant, an advanced tool based on artificial intelligence (AI) that provides continuous learning support to students. The assistant is used in distance learning programmes at FH Burgenland Continuing Education. With ChatGPT installed and integrated into the Learning Management System (LMS), it functions as an assistant with the ability to answer questions from students whenever they arise. Additionally, a course teacher verifies and corrects the AI’s responses within 24 hours to guarantee the system’s correctness and dependability.

It is becoming increasingly important to integrate educational chatbots, particularly those that use Socratic methods. The development of Large Language Models such as GPT-4 have made it possible to create more nuanced and interactive conversations, enabling chatbots to support more complex learning processes and provide personalised learning experiences. Two examples of chatbots that use Socratic methods to help students understand and learn the Scrum framework are the Scrum Tutor and the Scrum Assistant. These tutors were developed using GPTs and were evaluated through controlled testing and user feedback to ensure technical functionality and didactic effectiveness. The Socratic teaching method encourages critical thinking and self-reflection among learners, making it an effective approach for developing educational chatbots that actively involve students in the learning process.

Building and using a common terminology is of great importance for all collaborative work. On the other hand, well implemented tagging of documents by several “orthogonal” vocabularies provides a concise representation of context and topics of a textual data, which facilitates search and retrieval, as well as automated matching of “similar” documents in knowledge management systems. Manually finding relevant keywords for documents is a daunting task, time-consuming and prone to errors. Our “Voctractor” (from “Vocabulary Extractor”) application prototype [L1] addresses this challenge by streamlining both the vocabulary design and the keyword extraction workflow.

There is a growing body of work assessing the capabilities of Large Language Models (LLMs) for writing code. Comparatively, the analysis of the current state of LLMs with respect to software modeling has received little attention. Are LLMs capable of generating useful software models? What factors determine the quality of such models? The work we are conducting at ITIS-UMA investigates the capabilities and main shortcomings of current LLMs in software modeling.

Despite the excitement about Large Language Models (LLMs), they still fail in unpredictable ways in knowledge-intensive tasks. In this article, we explore the integration of LLMs with Knowledge Graphs (KGs) to develop cognitive conversational assistants with improved accuracy. To address the current challenges of LLMs, such as hallucination, updateability and provenance, we propose a layered solution that leverages the structured, factual data of KGs alongside the generative capabilities of LLMs. The outlined strategy includes constructing domain-specific KGs, interfacing them with LLMs for specialised tasks, integrating them with enterprise information systems and processes, and adding guardrails to validate their output, thereby presenting a comprehensive framework for deploying more reliable and context-aware AI applications in various industries.

The use of transformer-based pretrained language models (PLMs) arguably dominates the natural language processing (NLP) landscape. The pre-training of such models, however, is known to be notoriously data and resource hungry, which hinders their creation in low-resource settings, making it a privilege to those few (mostly corporate) actors, who have access to sufficient computational resource and/or pre-training data. The main goal of our research is to develop such a novel sample-efficient pre-training paradigm of PLMs, which makes their use available in the low data and/or computational budget regime, helping the democratisation of this disruptive technology beyond the current status quo.

Conversational agents and chatbots have developed rapidly in the past year to provide answers to user queries, drawing information from huge collections of data. From the user-side, the usefulness of conversational agents hinges on the accuracy of response in addition to user-friendliness and response speed. Here we briefly evaluate one of the most widely used chatbots, ChatGPT over a set of queries posed using multiple languages, to test its robustness and consistency, while running the experiment at two timepoints to monitor ChatGPT’'s evolution.

Open-source intelligence (OSINT) provides up-to-date information about new cyber-attack techniques, attacker groups, changes in IT products, updates of policies, recent security events and much more. Often dozens of analysts search a multitude of sources and collect, categorise, cluster, and rank news items from the clear and dark web in order to prepare the most relevant information for decision makers. A tool that supports this job is “Taranis NG” from the Slovakian CERT. This solution ingests information from many types of sources such as websites, RSS feeds, emails and social media channels and makes them searchable. It also supports the creation of reports and daily summaries. However, the number of sources and news items is continuously growing, making it increasingly difficult to search them purely manually. These circumstances call for the application of novel natural language processing (NLP) methods to make OSINT analysis more efficient.

The burgeoning landscape of AI legislation and the ubiquitous integration of machine learning into daily computing underscore the imperative for trustworthy AI. Yet, prevailing definitions of this concept often dwell in the realm of the abstract, imposing robust demands for explainability. In light of this, we propose a novel paradigm that mirrors the strategies employed in navigating the opaqueness of human decision-making. This approach offers a pragmatic and relatable pathway to cultivating trust in AI systems, potentially revolutionising our interaction with these transformative technologies.
