What the data for this category looks like
Industrial park marketing documents mainly come from investment prospectuses, industrial policy compendiums, resident enterprise directories, event invitation letters, and monthly operation reports compiled by park operation teams. The update rhythm is flexibly adjusted according to investment progress, policy adjustments, and changes in resident enterprises. Major policy updates have no fixed cycle, while routine monthly operation reports are updated monthly. Documents contain fixed fields: planned construction area of the park (unit: square meters), plot ratio, industry classification of resident enterprises, policy redemption application cycle (unit: working days), and per mu contribution reference value (unit: ten thousand yuan / mu). Document lengths range from single-page event notice short documents to dozens-of-page annual investment white paper long documents.
What constraints do these characteristics impose on the "document parsing and chunking" link
The multiple sources and format differences of industrial park marketing documents require the parsing module to support batch parsing of PDF, Word, Excel, and image formats, and avoid incorrect splitting of structured fields such as per mu contribution value and their units. Long documents such as annual investment white papers contain repeated basic park information. Context association must be retained during chunking to avoid semantic fragmentation caused by independent splitting. The resident enterprise directory is structured tabular data, which needs to be split by individual enterprise entries. Cutting by natural paragraphs will destroy the integrity of single enterprise information. The flexible update rhythm requires the parsing process to support incremental synchronization to avoid repeated parsing of full documents. Long policy text needs to be split by clause nodes to ensure complete semantics after chunking.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Industrial park annual investment white papers usually exceed 50 pages, with long parsing time, requiring adaptation to long document parsing duration |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Support batch uploading of multiple large documents such as park resident directories and policy compendiums |
maxChunkSize | 800–1200 characters | Industrial park documents contain structured fields and long policy texts. This range can retain semantic integrity |
chunkOverlap | 100–150 characters | Avoid truncation of context from policy clauses and enterprise directories after chunking |
PARSE_TABLE_MODE | Split by row | The resident enterprise directory is tabular data. Splitting by row can ensure the integrity of single enterprise information |
ENABLE_INCREMENTAL_PARSE | Enabled | Adapt to the flexible update rhythm of park documents, only parse modified document content |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: When the local deployment version is 4.8.22, the file parsing function is unresponsive or returns a parsing failure error. Cause: The built-in parsing plugin dependencies of this version are not loaded correctly, or the local port mapping configuration is incorrect.
- Phenomenon: JSON parsing errors are returned when parsing park policy documents. Cause: The document contains non-standard nested tables or special characters, causing the parsing module to fail to generate a compliant JSON structure.
- Phenomenon: When uploading a park investment prospectus with more than 50 pages, the parsing task times out and fails after continuous waiting. Cause: No parsing task queue is configured, and the single-task timeout threshold is set too short, so long document parsing cannot be completed within the limited time.
How to Confirm the Configuration is Correct
- An annual park investment white paper may be uploaded, the parsing task duration checked, and
PARSE_FILE_TIMEOUT_SECONDSadjusted to a value matching the actual duration. - An Excel directory containing resident enterprises may be uploaded, the parsed chunks verified to be split by individual enterprise entries, and the
PARSE_TABLE_MODEparameter adjusted. - A modified park policy document may be uploaded, verified to only re-parse modified content, and the
ENABLE_INCREMENTAL_PARSEconfiguration confirmed to take effect. - Parsing logs may be checked to confirm structured fields such as per mu contribution value and their units are not split, and the configuration effects of
maxChunkSizeandchunkOverlapverified.
