Business intelligence (BI) faces significant challenges in efficiently transforming large volumes of data into actionable insights. Today's workflows involve multiple complex stages, including data preparation, analysis, and visualization, requiring extensive collaboration between data engineers, scientists, and analysts using various specialized tools. These processes are time-consuming and tedious, requiring significant manual intervention and coordination. Intricate interdependencies between professionals and tools slow knowledge generation, delay decision making, and reduce organizational agility. These limitations underscore the critical need for more integrated and automated approaches to BI workflows.
Existing BI platforms have attempted to address workflow challenges through several approaches. Platforms such as Tableau, Power BI and Databricks have developed graphical user interfaces for data transformation and dashboard generation support. These platforms have integrated natural language interfaces to reduce manual operational burdens. Some research efforts have explored ontology-based methods to improve semantic information and query interpretation capabilities. Previous studies have focused on specific data analysis scenarios, investigating how data analysts interact with LLMs and identifying challenges such as contextual data retrieval and rapid refinement. However, these existing solutions primarily target individual tasks, but lack a unified and detailed approach to BI workflows.
Researchers from the State Key Lab of CAD&CG, Zhejiang University, Tencent Inc., Southern University of Science and technology and Peking University have proposed DataLab, a unified BI platform, integrating a comprehensive agent framework based on LLM with an augmented computing platform. notebook interface. It supports a variety of BI tasks in different data roles by seamlessly combining LLM support with user customization within a single environment. DataLab overcomes the existing limitations of fragmented, task-specific BI tools. The key innovation of the method lies in its ability to create a holistic solution that bridges the gaps between various functions, tasks and data tools, potentially revolutionizing the way organizations approach data analysis and decision-making processes.
DataLab's architecture is strategically designed around two main components: the LLM-based Agent Framework and the Computational Notebook Interface. The LLM-based Agent Framework employs a complex multi-agent approach to handle various business intelligence tasks. Each agent is specifically designed to address specific procedural requirements, using a directed acyclic graph (DAG) structure that ensures flexibility and extensibility. The framework uses several data tools, such as a Python sandbox for code execution and a VegaLite environment for rendering visualizations. The innovative design of the architecture allows nodes to represent reusable components such as APIs and LLM tools, while edges define the interconnections between these components.
DataLab shows remarkable performance on various BI tasks, consistently outperforming state-of-the-art LLM-based baselines across multiple benchmarks including BIRD, DS-1000, DSEval, InsightBench, and VisEval. Its superior capabilities are driven by its innovative domain knowledge incorporation module and complex data profiling strategy. For symbolic language generation tasks such as NL2SQL, NL2DSCode, and NL2VIS, DataLab produces high-quality results using domain-specific intermediate language specifications. DataLab outperforms existing frameworks like AutoGen by up to 19.35% on some benchmarks on complex multi-step reasoning tasks. This showcases the platform's advanced data understanding capabilities and a structured agent-to-agent communication mechanism that facilitates the discovery of detailed information.
In conclusion, the researchers present DataLab, a unified BI platform that integrates an LLM-based agent framework with a computational notebook interface. The platform introduces innovative components, including a domain knowledge embedding module, an agent-to-agent communication mechanism, and a cell-based context management strategy. These advanced features enable seamless integration of LLM support with user customization, addressing critical challenges in today's BI workflows. By providing a detailed solution that supports various data functions and tasks, DataLab represents a significant advancement in automated data analysis. Extensive experimental evaluations validate the platform's notable effectiveness and practical applicability in enterprise environments.
