Policy and Regulatory Basis Q&A for Petition Matter Handling: Document Parsing and Chunking

Policy and Regulatory Basis Q&A for Petition Matter Handling: Document Parsing and Chunking

What the data for this category looks like

The data for this category comes from the national petition information system, local petition systems, the 12345 citizen hotline platform, grassroots governance platforms, and historical petition archives. The update frequency is daily. Commonly processed documents include petition registration forms, acceptance notices, transfer and assignment letters, handling opinions, review and re-examination applications, resolution plans, and more. Structured documents are mostly multi-column tables or fixed-format government documents, with fields including request number, requestor information, request content, handling progress, policy basis, and others. There is no unified fixed unit field; specific fields vary based on business scenarios.

The data sources for this category include multi-column structured tables and fixed-format government documents. The parsing link must fully identify multi-column content to avoid losing business fields. The requirement for daily high-frequency batch uploads means the parsing link must adapt to timeout limits for large-capacity files and batch tasks. Fixed-format policy and handling-related documents require the chunking link to retain semantic context, avoiding splitting bound content between policy basis and handling requirements. Most historical archives are in outdated formats or scanned documents, so the parsing link must support non-standard document formats.

How to set the configurations

Reference only; verify against the target FastGPT release and deployment documentation.

Configuration ItemRecommended ValueRationale
chunkSize800–1200 charactersThe single-section policy basis and handling requirements in petition policy documents are moderately sized. Chunking within this range balances retrieval accuracy and contextual integrity
chunkSplitterBy paragraph + semantic boundaryPetition documents are mostly structured government statements. Chunking by semantic boundaries preserves the associated logic between policy basis and handling procedures
customPdfParseEnabledAdapts to the multi-column layout of standard government PDF forms for petition matters, fully identifying all field content from the original document
PARSE_FILE_TIMEOUT_SECONDS120–180 secondsAdapts to large-capacity petition archive files uploaded in daily batches, preventing parsing tasks from failing due to insufficient default duration
chunkSettingModeManual configurationAdjust chunking rules separately for multi-column Excel tables and fixed-format documents, adapting to the special structure of business data for this category

Three common mistakes

  • Phenomenon: When uploading a multi-column petition registration form Excel file, only the first two columns of content are identified. Cause: The customPdfParse configuration is not enabled, and the default parsing rules cannot adapt to the multi-column layout of government tables.
  • Phenomenon: Frequent timeout errors occur when submitting batch daily update petition archive parsing tasks. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter is not adjusted, and the default timeout duration is insufficient for processing large-capacity batch files.
  • Phenomenon: Complete handling-related content cannot be obtained when searching for policy basis. Cause: Chunking is only done by fixed character length, and semantic boundary splitting is not enabled, causing policy basis and handling requirements to be split into different chunks.

How to confirm the configuration is correct

  • A single multi-column petition Excel table should be uploaded, and the parsed data fields checked to confirm they cover all columns of the original table.
  • A standard-format petition acceptance notice PDF should be uploaded, and the parsed text checked to confirm it retains the paragraph and format associations of the original document.
  • A single large-capacity petition archive parsing task should be submitted, and confirmation made that the task does not trigger a timeout error within 120 seconds.
  • Policy basis keywords should be entered for retrieval, and confirmation made that the returned result chunks contain complete policy content and associated handling requirements.
