**Context is becoming the missing link that transforms powerful AI models into truly intelligent systems.** In 2026, the next leap in AI comes from understanding *context* \- user intent\, environment\, history\, and goals\. This shift separates generic outputs from meaningful\, real\-world outcomes\. Join this Meetup to explore why context is the foundation of more reliable, human-centered, and transformative AI. We’ll dive into the role of **knowledge graphs** and how they help AI systems make sense of complex information and connect insights the way humans do. **16:30 - Welcome snacks and drinks** #### **17:00 - Talk 1** #### **Why Context Matters in AI – Grounding LLMs** Aniket Mitra will explore how enterprise data captures the *DNA of an organisation*—the what, where, when, who, how, and ultimately the why behind decisions. He will explain why siloed data limits AI-driven decision-making, and how knowledge graphs provide a unified semantic layer that enables trustworthy, AI-powered control towers across the value chain. **Aniket Mitra** – Aniket Mitra is the founder of Computationele Wetenschapsgroep (CW) which is a technology development SME that specialises in designing, building & scaling Knowledge Graphs for enterprise customers across industry verticals like retail, manufacturing & logistics. **17:30 - Talk 2** **Building Trustworthy AI in Regulated Sectors – Moonjelly, Knowledge Graphs, and the Context Layer** Surajeet Bhuinya will share how a dedicated context layer helps AI systems understand how organisations actually work. Using Moonjelly as a practical example, he will show how connecting people, documents, and processes into a living enterprise graph creates context unique to each industry and use case—leading to better decisions, clearer accountability, and real business impact. **Surajeet Bhuinya** – Surajeet Bhuinya is the founder of DataPebbles, a leading Data & AI company in the Netherlands. With 25+ years of IT experience, he operates at the intersection of data, AI, and innovation, building scalable, practical AI systems that deliver measurable business impact. He is also the founder of Moonjelly, a platform that connects people, documents, and processes into a living enterprise graph, enabling teams to understand context, see impact, and act with confidence. **18:00 - Talk 3** **ReviewGraph – Using Knowledge Graphs to Predict Customer Satisfaction and Extract Hidden Insights** Lifeng Han will present ReviewGraph, a graph-based framework that transforms customer reviews into knowledge graphs to predict ratings and uncover hidden insights. He will compare this approach with traditional NLP methods and LLMs, highlighting how knowledge graphs offer strong performance with lower computational cost, greater interpretability, and promising integration with RAG systems. **Lifeng Han** – Researcher, **[4D Picture](https://www.linkedin.com/company/4dpicture/)** Project. Dr. Han has authored 50+ peer-reviewed publications and previously worked at the University of Manchester on Healthcare NLP. His PhD focused on machine translation (ADAPT Centre, DCU, Ireland). **18:30 - 19:30 - Networking, drinks and snack**

**ArnhemJUG** We are excited to announce the first meetup of 2026. We are welcomed by OpenValue Arnhem for the January meetup! **Agenda** * 17:00 CET walk-in * 17:30 – 18:30 Food and drinks * 18:30 – 19:30 talk: **Bigger Unit Tests are Better - why small unit test classes will slow you down** by **Peter Schuler** * 19:30 – 19:45 break * 19:45 – 20:45 talk: **Creating effective and objective architectural decision records** by **Piet van Dongen** * 20:45 – 21:30 drinks **Bigger Unit Tests are Better - why small unit test classes will slow you down** Do you take care that every class in your system has a separate unit test class? Are you a proud Test-First advocate? A code coverage evangelist? Are you the Sonar police in your team? Do you take pride in knowing all the quirks of your mocking framework? Then this session might be a cold shower for you. You will see how the general approach to unit testing might harm your flexibility. But a few simple changes in your approach will make your life better, your coding faster, your refactoring easier and your understanding of the business requirements stronger. In this presentation, you will learn new strategies that will help you make your unit tests bigger. First, guided by clear code examples, we will look at why having many small test classes may harm you. Secondly, you will understand why making the tests bigger is such an important improvement. And lastly, you will learn techniques and tricks that will help make your unit tests bigger. **About Peter Schuler** Peter is a lifelong Java developer with a passion for TDD and code quality. Lately he has become a Java community lead for the Rabobank as a side hustle. In his off time, he likes to work in the garden or goes for a short run. **Creating effective and objective architectural decision records** Documenting decisions is like eating your veggies as a kid: they keep telling you it’s good for you, but you just hate doing it. Architectural Decision Records (ADRs) to the rescue! ADRs are perfect for just-in-time, just-enough documentation for engineering teams and organizations. During this session, you will learn how to make architectural decisions effectively and objectively by: * Learning the structure of a good ADR (no more walls of text that nobody reads anyway!) * Practicing how to turn subjective choices into objective ones (no more pros and cons lists and tribal conflicts!) * Creating editable diagrams, fast (no more spending hours wrestling tools that your collaborators don’t know how to use!) * Collaborating quickly with technical and non-technical stakeholders (no more hours of Tower of Babel meetings!) * Reporting the decision using effective language and fit-for-audience diagrams (no more writing reports that end up unread in drawers!) Do you want to learn how to facilitate good decision making without spending weeks looking for consent? Then join this session and you will walk away a better software architecture decision facilitator. **About Piet van Dongen** Piet van Dongen is a senior software architect and engineering consultant at OpenValue, helping organizations solve complex technology challenges through effective software practices.

**Beyond real data: hoe synthetische data AI mogelijk maakt** AI-modellen zijn zo goed als de data waarop ze worden getraind. In de praktijk vormt juist die data vaak de bottleneck: beperkte beschikbaarheid, datakwaliteit, privacywetgeving en hoge kosten maken het lastig om modellen betrouwbaar en schaalbaar te ontwikkelen. Toegang tot kwalitatieve data is dus allesbehalve vanzelfsprekend. Vaak moet je door grote hoeveelheden ruwe data waden voordat er iets bruikbaars overblijft, terwijl wet- en regelgeving steeds strengere eisen stelt aan wat je mag verzamelen, opslaan en gebruiken. Hoe ga jij om met deze uitdagingen? Wat werkt goed in jouw projecten, en waar loop je tegen beperkingen aan? Vaak leidt dit tot één veelbelovende oplossing: synthetische data - kunstmatig gegenereerde data die zich gedraagt als echte data. In deze Meetup duiken we technisch in dit concept, ontdekken we de mogelijkheden en beperkingen, en bespreken we kritisch de risico’s op het gebied van bias, ethiek en beleid. We sluiten af met een korte, hands-on workshop, waarin je zelf synthetische data leert genereren en evalueren. Zo kun je direct ervaren hoe het werkt en het concept later toepassen in je eigen projecten. **Wat synthetische data mogelijk maakt** * Sneller, veiliger en goedkoper AI-modellen trainen * Data delen zonder privacy- of compliance-zorgen * Een eerlijkere data-competitie, waarbij ook kleinere organisaties kunnen concurreren **Wat je meeneemt uit deze Meetup** * Waarom data vaak de echte bottleneck is, en niet AI zelf * Wat synthetische data is - en wat het niet is en wat op dit moment de mogelijkheden zijn. * Concrete voordelen voor AI-ontwikkeling, privacy en schaalbaarheid * Inzicht in risico’s, ethische vraagstukken, beperkingen en randvoorwaarden * Hoe je omgaat met data limieten (anonimiseren, pseudonimiseren, simuleren, synthetiseren) * Praktische inspiratie en ervaring met het zelf genereren van synthetische data * Zelf aan de slag gaan met synthetische data, waardoor je dit later als concept kan toepassen in je eigen projecten. Sluit aan op donderdagavond 29 januari op ons kantoor op steenworp afstand van het station van 's-Hertogenbosch. Programma: 17.00 - 17.30: Inloop en ontvangst 17.30 - 18.15: Buffet 18.15 - 20.00: Uitleg & Workshop "Synthetische data" 20.00: Napraten met een drankje Parkeren kan bij de P&R naast ons pand (wij verzorgen een uitrijkaart).

Donderdag **29 januari 2026** is het weer tijd voor onze **Techday**: hét vaste moment waarop we kennis delen, elkaar inspireren en nieuwe ideeën direct in de praktijk brengen. Deze Techday is niet alleen voor developers, maar juist ook voor collega’s uit HR, Sales, Marketing, Operations en andere disciplines. Deze editie pakken we het aan als een **conferentie in het klein**. Drie sprekers, drie verhalen, één middag – *drie verhalen voor de prijs van één*. **Wat kun je verwachten?** • **Idzard** neemt je mee in **Product Goals** Waarom zijn ze zo belangrijk? En waarom zou elke product professional ze moeten kennen (en gebruiken)? • **Dave** laat je ervaren wat **Storytelling** doet Waarom onthouden we verhalen beter dan feiten? En hoe kun je storytelling inzetten in je dagelijkse werk? • **Jeroen** duikt in **Prototyping met AI** Hoe gebruik je AI om sneller ideeën te verkennen, testen en aanscherpen?Alle talks zijn **interactief**: geen achteroverleunen, maar meedoen. Je wordt uitgedaagd om de ideeën **direct toe te passen**, zodat je na afloop niet alleen geïnspireerd bent, maar ook echt iets nieuws kunt.Neem mee: goede zin en je laptop voor het maken van een prototype. **Wanneer:** Donderdag 29 januari 2026 **Wat:** Techday RE – conferentie-editie “Verhalen en beelden” **Voor wie:** Iedereen (!) die nieuwsgierig is en wil leren **Agenda** 14:45 - 15:00 - Inloop 15:00 - 15:45 - Product Goals 15:55 - 16:30 - Storytelling 16:35 - 18:00 - Prototyping met AI 18:00 - 19:00 - Eten We zien je graag op de Techday!

We’re heading into the south eastern Veluwe for a stunning scenic route that stays wonderfully quiet and almost deserted for a big part of the way, before building up to a truly spectacular grand finale! After around 6 km we reach the mysterious “Altar of the Loenermark” (Altaar van de Loenermark). I have no idea what it is, so we’ll discover it together. From there we continue through the beautiful heather and forest landscapes of Loenermark, one of those places where the Veluwe feels wide, wild, and open. Next we pass one of the quirkiest monuments in the Netherlands: the Ijkbasis Loenermark 1957–2007, a tribute to the calibration of measurement instruments from the past. The calibration itself might not sound exciting, but the location absolutely is, right in the middle of wide open heather, with big skies and that endless Veluwe feeling. It also marks about 11 km into the hike, a perfect spot to take our lunch break. After lunch we walk straight through the iconic National Park Veluwezoom, famous for its rolling grasslands and its fluffy semi wild cows. To finish in style, we end at Paviljoen De Posbank for a well earned snack or drink with a view over what many call the most spectacular heather of the Netherlands, complete with rolling hills. From there we head down towards Rheden, where you can easily catch the train or bus home. This is not a loop hike! **📍When and where to meet?** We’ll meet at 10h at busstop Loenen, Leeuwenbergweg. https://maps.app.goo.gl/LC3nNJQo57B5NnSy8 We are leaving a bit earlier otherwise we will find Paviljoen Posbank closed, which would be very sad. ⏰ We **start walking a few minutes after meeting up** — we don’t wait for latecomers, as the forest calls and daylight is short this time of year. **🚗 Coming by car?** This is not a loop hike. If you park in Loenen, you’ll need to make your own way back from Rheden afterwards. **⏸️ Planned Breaks** After **11 km**: Lunch break at **Ijkbasis Loenermark** (bring your packed lunch, this spot is truly in the middle of nowhere) **20 min** [https://maps.app.goo.gl/S5vAEpadAJs93ZrC7](https://maps.app.goo.gl/S5vAEpadAJs93ZrC7) After **19 km**: Snack or drink at **Paviljoen De Posbank** [https://maps.app.goo.gl/wowuqj3sRY5hcid37](https://maps.app.goo.gl/wowuqj3sRY5hcid37) **💸 Payment** Please pay as soon as you sign up: To keep things fair for everyone, if we don’t receive your payment within 48 hours, we will need to remove you from the participant list. If there’s a waiting list, this will happen sooner (in less than 48 hours). If that happens, no worries — you’re always welcome to sign up again if there’s space. 🌟 Early Bird Deal! Join now for just €4 — available for 3 days (72h). After that, the price will be €5. https://tikkie.me/pay/59muhp2djpv45gc6hgh6 **👟 Good to know** * Refund policy: Cancellations are fully refundable up to 1 week before the event (This is Friday 23 January at 23h59). After this period, the fee becomes non-refundable. * Hike difficulty: Our hikes are moderately challenging. Please only join if you’re confident you can keep up with the group’s pace (5 km/ h)— it’s more fun for everyone when we can walk together without long waits. * If the pace is too challenging: We may kindly suggest you continue at your own pace. We’ll give you clear directions to the nearest bus or train so you can return comfortably. * At your own risk: You participate at your own risk, so please make sure you have appropriate insurance coverage for outdoor activities. * Payment note: With Tikkie we only see initials (e.g., J. Doe instead of John Doe). Please include your Meetup name in the payment note so we can match it easily. * Friends joining: If you bring a friend, make sure they also register and pay. * What to bring: Snacks, lunch, and water/ or hot thee/ coffee. * Stay connected: Join our WhatsApp group to be the first to hear about future hikes — ask for the QR code during the hike. * T-shirts: Fairwear-certified organic cotton, eco-friendly inks — €25. Sustainable, odor-resistant, and perfect for hiking. Let us know your size and we’ll bring one for you.

On Sunday evening, we come together to soften the transition into a new week, creating a moment to pause, reflect, and be present. During this 1-hour session, we will move through: * a guided meditation to arrive and settle into the body * a journaling practice to connect with what is alive within you * a sharing circle, where you are welcome to speak or simply listen No previous experience with meditation, journaling, or sharing circles is needed. You are welcome exactly as you are. This is a space where every question, every feeling, and every story is met with care — a space to be witnessed, and to witness other women, with openness, respect, and presence. You can join from the comfort of your home and participate in the way that feels right for you. 🕊 Please have a notebook and pen nearby, and find a quiet, comfortable space where you can be undisturbed for the hour. ✨ Reminder: This event runs on a **donation basis**, so please give what feels right for you.

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.

Session Abstract **No Map Required: Geospatial Analytics Directly in Your Data Warehouse** Think geospatial analysis requires specialized GIS software? Think again. This session introduces you to shapefiles and spatial operations right inside your database—no mapping application required. We'll demystify shapefiles (what they are, how they work, and where to get them) and show you how nearly every modern database —from DuckDB to Snowflake, supports spatial operations. You'll see practical demos covering spatial joins, distance calculations, and how to determine if two shapes interact with each other. Whether you're a data engineer optimizing delivery routes, an analyst aggregating metrics by geography, or a BI developer building location-aware dashboards, this session will show you how to unlock powerful spatial capabilities already built into your database stack—no specialized tools required. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

**New Dojo Location!** **Draft Day Columbus** 1130 Dublin Road Columbus, OH 43215 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out.
