The document parsing and chunking features in FastGPT v4.17.0 adapt to the government and enterprise IT service ledger summary and report generation scenario. Below are specific configurations and considerations.
What Data in This Category Looks Like
Government and enterprise IT service ledger data mainly comes from state-owned enterprise and enterprise communication operation work order ledgers, customer service ledgers, network equipment operation ledgers, and similar sources. Data updates run on a natural day or weekly basis. A single document usually includes two parts: structured tables and unstructured notes. Core fields include ledger number, associated equipment ID, processing period, fault classification, disposal result, handling personnel, and similar items. Units involve business-specific measurement standards such as hours, units, and times.
What Constraints Do These Characteristics Impose on the Document Parsing and Chunking Link
The high proportion of structured tables requires the parsing link to retain row and column association relationships for tables. This avoids splitting that breaks field correspondence. The daily or weekly update rhythm requires the chunking link to support batch parsing scheduling for batch documents. This adapts to timed synchronization business processes. The presence of business-specific fields and units requires retaining field context during chunking. This prevents splitting associated information into different chunks. The presence of long-text notes requires the chunking strategy to balance content integrity and semantic coherence. This stops business logic from being split across chunks.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the field association length of ledger documents, avoids splitting core business fields |
chunkSplitter | Paragraph + semantic splitting | Adapts to the mixed document structure of structured tables and unstructured notes, retains content coherence |
customPdfParse | Enabled | Adapts to standard PDF documents commonly used for government and enterprise ledgers, retains table and layout information |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to storage and parsing requirements for single batch ledger documents, avoids parsing failure of large files |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to parsing time for long ledger documents, prevents timeout interruptions |
chunkSettingMode | Manual configuration | Adapts to business-specific field association requirements, flexibly adjusts chunking parameters |
Three Common Misconfigurations
- Phenomenon: PDF parsing returns timeout or format error prompts, and table content is lost after parsing. Cause:
customPdfParsefor standard PDF documents is not enabled, or the value ofPARSE_FILE_TIMEOUT_SECONDSis insufficient, leading to parsing interruption of long ledger documents. - Phenomenon: Parsing results of batch uploaded ledger documents have no source identifier, making it impossible to distinguish chunked content of individual documents. Cause: Metadata of the original file is not bound in the chunking configuration, resulting in chunked results that do not carry file identifier fields.
- Phenomenon: Knowledge base search tests fail to hit target ledger content. Cause: The
chunkSizevalue is too large, splitting core business fields into different chunks, or thechunkSplitterconfiguration does not retain field association context.
How to Confirm Configuration Is Correct
- Upload a single standard PDF ledger document. Check whether the table structure in the parsing result is complete to confirm the configuration takes effect.
- Batch upload multiple ledger documents. Check whether chunked results carry the unique identifier of the original file to confirm metadata binding configuration is correct.
- Adjust chunking parameters. Verify whether chunked content retains the association relationship of core business fields to confirm the chunking strategy adapts to the document structure.
- Trigger a parsing task. Confirm that parsing time does not exceed the preset timeout configuration value, with no timeout errors.
