Knowledge Graphs – pragmatische aanpak en best practices [English spoken]

In today’s data-driven landscape, the concept of a knowledge graph has emerged as a pivotal framework for managing and utilizing interconnected data and information. Stemming from Google’s proclamation that shifted the focus from searching for strings to understanding entities and relationships, the term encapsulates a network of interconnected entities and concepts, facilitating data integration, sharing, and utilization within organizations.

Amid the widespread adoption of knowledge graphs across diverse domains, ensuring the accuracy, reliability, and consensus of semantic information becomes an imperative. The construction and utilization of these graphs present multifaceted challenges, ranging from ensuring data quality to scaling and adapting to evolving contexts.

Implementing a successful Knowledge Graph initiative within an organization demands strategic decisions before and during its execution. Often overlooked are critical considerations such as managing trade-offs between knowledge quality and other factors, prioritizing knowledge evolution, and allocating resources effectively. Neglecting these facets can lead to friction and suboptimal outcomes.

This half-day seminar delves into the technical, business, and organizational dimensions essential for data practitioners and executives embarking on a Knowledge Graph initiative. Offering insights gleaned from real-world case studies, the seminar provides a comprehensive framework that combines cutting-edge techniques with pragmatic advice. It equips participants to navigate the complexities of executing a knowledge graph project successfully.

Moreover, the session addresses pivotal strategic dilemmas encountered during the design and execution phases of knowledge graph projects, and outlines potential approaches to tackle these challenges, empowering attendees with actionable strategies to optimize their initiatives.
