Data Characteristics
Medical insurance settlement quality documents originate from various sources. These include policy documents, payment standards, service agreements, and operational guidelines published by medical insurance bureaus. They also include internal settlement process guidelines and audit reports from medical institutions. Updates typically occur quarterly or annually, with ad-hoc updates for policy changes. Documents are often in PDF format with diverse structures, including directories, chapter titles, tables, and appendices. Content frequently contains medical terminology, administrative division codes, disease diagnostic codes (e.g., ICD-10), surgical procedure codes (e.g., ICD-9-CM-3), generic drug names, medical service item codes, and numerical information like amounts and percentages. Units include CNY, percentages, person-times, and days.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
The diverse sources and complex structure of medical insurance settlement documents require parsers to handle various formats like PDF and DOCX effectively. Accurate identification of chapters, titles, lists, and tables is crucial for logical and complete chunking. Frequent policy updates necessitate incremental updates and version management in the knowledge base. Chunking must preserve sufficient context to differentiate between old and new policies. The abundance of specialized codes and numerical information means simple text chunking can lead to semantic loss. Chunking must therefore focus on the association between codes and their meanings, ensuring numerical information and related descriptions are retained together to prevent key information from being isolated. Parsing non-public data sources, such as internal Confluence pages, requires flexible connectivity and access control.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Chunk Length) | 800–1200 characters | Medical insurance policy clauses are often long, requiring sufficient context to understand complex rules and conditions. |
Chunk Overlap Length (Chunk Overlap Length) | 100–200 characters | Ensures sufficient overlap between adjacent chunks to maintain semantic coherence, especially where rule clauses intersect. |
File Parsing Timeout | 600 seconds | Parsing large PDF documents can be time-consuming; this avoids frequent timeouts for complex documents. |
Parsing Strategy | Chunk by Title | Medical insurance documents often use a chapter-title structure; chunking by title helps maintain logical integrity. |
Max File Size | 500 MB | Accounts for potentially large medical insurance audit reports or regional policy compilations. |
Enable Table Extraction | Yes | A large amount of information, such as medical insurance payment standards and service item lists, is presented in tabular form. |
Common Pitfalls
- After document parsing, codes or numerical values in some policy clauses become disconnected from their descriptions. This happens when chunking fails to adequately consider the semantic relationship between codes and text, leading to key information being split.
- When dealing with non-public resources like internal Confluence, the system may fail to parse content or return empty data. This is due to insufficient network configuration or authentication, preventing the parser from accessing the target page.
- When importing large PDF files, the parsing process might hang or error out, potentially showing a
PARSE_FILE_TIMEOUT_SECONDSerror. This occurs because the file size or content complexity exceeds the default parsing time limit.
How to Verify Correct Configuration
- Randomly select multiple medical insurance settlement documents from different sources and formats. Check the completeness and logical coherence of the parsed chunks, especially for sections containing policy clauses, codes, and monetary values.
- For medical insurance payment standard documents, verify that table data is accurately extracted and structured, ensuring numerical values are not separated from their corresponding item descriptions.
- Attempt to import policy documents from different years. Confirm the system can identify and process document version differences and display their content correctly.
- Select documents with complex nested structures or numerous charts. Check that the parsed chunks accurately reflect the original structure, ensuring no critical information is lost.
