What the data for this category looks like
The entities involved in this category include civil affairs bureau assistance sections, subdistrict and township civil affairs offices, community committees, and verification centers. Daily processed documents include minimum living security application forms, family economic status verification reports, household survey forms, democratic appraisal records, public notice materials, and assistance approval forms. Data mainly comes from low-income population dynamic monitoring platforms, resident family economic status verification systems, and shared data from public security, human resources and social security, medical insurance, housing construction, and tax authorities. The update frequency is monthly. Documents contain structured fields and unstructured content. Some documents include embedded image resources such as household photos and public notice screenshots. Fields cover dimensions including family population, income, property, and member relationships.
What constraints do these characteristics impose on the "document parsing and chunking" link
Monthly updated data sources require the parsing process to support incremental synchronization and batch processing, to avoid repeated parsing of full datasets. Cross-department shared data has inconsistent formats, including Excel spreadsheets, PDF forms, structured documents and other types. Some Excel files contain embedded images, so multi-format parsing support is required. Documents take the family as the core unit. Splitting must avoid breaking complete logical blocks such as family economic status and member relationships. Embedded image resources must be correctly extracted and associated with corresponding text. Otherwise, the large model cannot be provided with complete policy and basis evidence. At the same time, the accuracy of parsing results directly affects subsequent assistance qualification review, so parsing confidence must be ensured.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the typical length of family-related paragraphs in civil affairs documents, avoiding splitting complete descriptions of family economic status or member relationships |
chunkSplitter | Split by family unit + paragraph | Matches the family-centric structure of documents in this category, ensuring each chunk after splitting contains complete family-related policy basis |
customPdfParse | Enabled | Supports extracting embedded images from various document types and associating household photos, public notice materials and other images with corresponding text chunks |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to parsing time required for batch processing cross-department shared data, preventing parsing interruptions caused by large data volumes |
UPLOAD_FILE_MAX_SIZE | 500 MB | Supports batch uploading of bulk documents such as monthly updated verification reports and public notice materials |
chunkSettingMode | Custom | Allows adjusting chunking rules for the special structure of civil affairs documents, adapting to business requirements of this category |
Three common mistakes
- Issue: After parsing an Excel document containing embedded images, the images are not correctly extracted or associated with corresponding text. Cause: The configuration for embedded image parsing is not enabled, resulting in lost image resources.
- Issue: Parsing tasks time out and fail when uploading monthly verification reports in bulk. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default duration cannot cover the parsing time required for bulk data. - Issue: Chunking results split complete paragraphs containing family income and member relationships. Cause:
chunkSplitteris not set to split by family unit; splitting only by regular paragraphs leads to logical breaks.
How to confirm the configuration is correct
- Upload a test minimum living security application form PDF document, check if the embedded household photos are retained in the parsing results and associated with corresponding household survey text chunks.
- Upload an Excel family economic status verification report containing embedded images, check if image resources are extracted and displayed in the parsing results.
- Review the chunked text content, confirm that each chunk contains complete family-related policy basis and does not split core logical paragraphs.
- Check the parsing task time logs, confirm that the time does not exceed the duration set by
PARSE_FILE_TIMEOUT_SECONDS.
