Power BI: Your Semantic Model with Synonyms

Key insights

• Power BI Semantic Model is a metadata layer that organizes tables, columns, relationships, and business logic for easier analytics and reporting. Adding Synonyms lets users find data elements with different keywords, improving natural language queries and AI-driven searches.
  
• AI-Enhanced Interaction: The new Copilot feature now creates DAX queries using hierarchies and folder names from the semantic model. AI tools also include a search box for fields and visibility indicators for hidden fields to make data preparation faster.
  
• One-Click Notebooks (Preview): Power BI now offers instant notebooks connected to semantic models. These notebooks help users analyze their models, follow best practices, and monitor memory usage with expert recommendations.
  
• Direct Lake Semantic Models: Users can build Direct Lake semantic models in Power BI Desktop and connect to more sources like Fabric SQL databases and Lakehouses. This allows live edits and flexible multi-source modeling.
  
• User Query Improvements: Enhanced Copilot understanding allows better use of synonyms during natural language queries, making it easier to explore data with personalized questions.
  
• Community Collaboration: A new gallery for sharing community-created notebooks encourages teamwork by letting users share analysis tools and improve semantic modeling together.
  

Introduction: Power BI Semantic Model Evolves with Synonyms

The latest YouTube video by Reza Rad (RADACAD) [MVP] explores how Power BI continues to push the boundaries of business intelligence. The focus is on enhancing the Power BI Semantic Model through the use of synonyms, making the platform more accessible and effective for users. As organizations increasingly rely on data-driven decision-making, these innovations are timely and crucial. The video highlights not just technical upgrades, but also practical advantages and usability improvements for both analysts and business users.

By integrating synonyms and leveraging AI-powered features such as Copilot and Generative AI, Power BI aims to streamline the process of querying and interpreting complex datasets. This approach supports users with different levels of technical expertise, making it easier for everyone to interact with data using natural language and intuitive search methods.

Understanding Semantic Models and the Role of Synonyms

At its core, the Power BI Semantic Model acts as a bridge between raw data and meaningful analytics. It organizes tables, columns, measures, and relationships, providing a structured environment for self-service reporting and analysis. However, traditional models often required users to know exact field names or technical terms, which could limit accessibility.

Synonyms address this challenge by allowing users to assign alternative names or keywords to data elements. For example, a column labeled "Revenue" could also respond to queries for "Sales" or "Income." This flexibility is especially valuable when using natural language features like Q&A or interacting with AI tools, as it enables more conversational and intuitive data exploration.

Key Innovations in 2025: AI, Notebooks, and Direct Lake Modeling

The video outlines several important updates introduced in 2025. First, Copilot in Power BI now generates DAX queries using user-defined hierarchies and folder names, providing smarter AI assistance. Additionally, an enhanced search box within semantic models helps users quickly find fields, while visibility indicators make it easier to manage hidden or sensitive data.

Another significant advancement is the introduction of one-click notebook experiences. These notebooks, such as the Best Practices Analyzer and Memory Analyzer, are directly linked to semantic models. They offer expert recommendations and help users monitor performance and optimize memory usage without needing deep technical knowledge.

Moreover, Direct Lake semantic models can now be created in Power BI Desktop. This allows seamless integration with more data sources, such as Microsoft Fabric SQL databases and Lakehouses, enabling real-time editing and truly flexible multi-source modeling. These features work together to empower users to build, maintain, and optimize semantic models with unprecedented ease.

Enhancing User Experience: Synonyms, Personalization, and Community Collaboration

Even though direct upgrades to synonym management are subtle, the overall improvements to personalization and natural language querying suggest better synonym utilization. Users can now tailor suggested questions and benefit from Copilot’s improved understanding of synonyms, making data exploration smoother and more engaging.

The Power BI Community notebooks gallery further enhances collaboration by allowing users to share analysis tools and experiences. This collective approach accelerates knowledge transfer, helping both novice and advanced users learn from each other and adopt best practices faster. The combination of AI integration, community resources, and improved search features results in a more inclusive and productive environment for all Power BI users.

Balancing Innovation with Usability: Tradeoffs and Challenges

While these advancements bring considerable benefits, they also introduce new challenges. For instance, expanding AI-driven features means users must trust automated suggestions and recommendations. Striking the right balance between automation and user control is essential to prevent errors or misinterpretations of data. Additionally, as models become more dynamic and complex, maintaining data quality and consistency requires ongoing attention.

Another challenge lies in managing large, multi-source semantic models. Although search and visibility tools improve navigation, users still need a solid understanding of their data landscape to avoid confusion. Training and documentation remain important to ensure that the flexibility offered by synonyms and AI features does not compromise accuracy or security.

Conclusion: The Future of Power BI Semantic Modeling

In summary, the innovations presented in Reza Rad’s video mark a significant step forward for Power BI. By integrating synonyms, AI-powered assistance, and collaborative tools, Microsoft is making semantic modeling more intelligent, adaptable, and user-friendly. These changes empower users to extract insights more efficiently, personalize their experience, and collaborate effectively.

However, as with any technological leap, careful management and user education are vital to maximize benefits and minimize risks. As Power BI evolves, organizations will need to balance automation with oversight to ensure reliable, accurate, and actionable analytics for all.
