Query Symbolically or Retrieve Semantically? A Dataset and Method for Semi-Structured Question Answering
TL;DR
Retrieval-Augmented Generation (RAG) systems—which fetch relevant documents to answer questions—rely on semantic similarity matching, which fails on semi-structured data requiring exact filtering or aggregation across multiple records. Researchers built a dataset and hybrid method combining symbolic query execution with semantic retrieval to handle both unstructured text and structured attributes.
✦ Why It Matters
Engineers building QA systems can now choose between or combine symbolic and semantic retrieval based on data structure, improving accuracy on mixed-format corpora.
Key Takeaways
- Utilize DualGraph for improved accuracy in question answering tasks.
- Leverage both semantic and symbolic querying for complex datasets.
- Explore the SpecsQA benchmark for testing retrieval systems.
- Integrate Textual and Symbolic Knowledge Graphs in your applications.
How It Works
DualGraph operates by representing documents through two complementary structures: a Textual Knowledge Graph that captures semantic relationships for retrieval and a Symbolic Knowledge Graph that allows for precise querying of structured data. This dual representation enables the system to effectively combine the strengths of both semantic and symbolic approaches, allowing for more accurate and contextually relevant answers to complex queries.
