Deep Analysis & Enterprise Applications

Large Language Models are being integrated into Geographic Information Science (GeoAI) to enhance spatial data analysis. Early applications include GIS tool operation, Retrieval-Augmented Generation (RAG) for geospatial content, and natural language interfaces for geospatial databases.
Geospatial Knowledge-Base Question Answering (GeoKBQA) systems traditionally relied on handcrafted rules and templates. Recent neural-based approaches improve generalization but often require extensive fine-tuning data, a gap our multi-agent system addresses.
Multi-agent LLM frameworks decompose complex tasks into specialized subtasks, improving performance and interpretability. Our system uses this paradigm for GeoKBQA, with agents for intent analysis, concept retrieval, geospatial relation retrieval, property retrieval, operator building, and query generation.

Concept Grounding Case Study: 'Which church is the farthest from Perling?'
Problem: Single-agent LLMs often struggle with fine-grained semantic grounding, leading to over-inclusive results. For the query 'Which church is the farthest from Perling?', a single agent might map 'church' to 'amenity=place_of_worship'.
Solution: Our multi-agent pipeline correctly grounds 'church' to 'building=church' using the Concept Retriever, ensuring the intended class constraint is preserved and yielding a semantically faithful top-1 result. This is crucial for precise geospatial reasoning.
