What the Data for This Category Looks Like
Chemical raw material financing daily report data primarily comes from public financing filing information released by local financial supervision bureaus, project announcement channels of chemical park management committees, and dynamic updates from third-party industry information aggregation platforms. Data is updated daily, covering chemical raw material-related financing projects that completed filing or disbursement on the same day. Each single document includes standardized fields: financing entity name, financing amount (unit: ten thousand RMB), financing term (unit: month or natural day), fund usage, disbursing institution, filing date, affiliated administrative region. Documents are released as structured tables or plain text entries. Some parks include project filing numbers and specific raw material category details.
What Constraints Do These Characteristics Impose on Knowledge Base Retrieval and Recall?
The data characteristics of this category impose multiple constraints on the retrieval and recall link. First, multi-source heterogeneous release formats require the preprocessing step to support both table and plain text formats, to avoid field extraction bias. Second, the daily update frequency requires an incremental sync strategy that only pulls newly added data each day, reducing resource consumption from full indexing. Third, the fixed unit rule for financing amount (ten thousand RMB) requires automatic unit prefix matching during retrieval, to avoid unit confusion for amount values. Fourth, specific chemical raw material categories bound to fund usage require precise entity recognition, to ensure recall results exactly match the raw material types in user queries.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Chemical raw material financing daily reports are mostly structured table documents. Single-document parsing time is longer than general text. 300 seconds covers parsing needs for most single documents. |
Recall count | Top 8–12 entries | Single entries in this category's daily reports have concentrated fields. Too many recall results cause redundancy. 8-12 entries cover common user needs for same-day or recent 3-day financing information. |
Similarity threshold | 0.72–0.80 | Chemical raw material category names have synonymous expressions such as "polyethylene" and "PE". Too low a threshold introduces irrelevant results. This range balances precision and recall rate. |
Chunk size | 600–800 characters | The total structured information for a single financing daily report entry is approximately 500-700 characters. Segment length covers complete single entries, avoiding semantic split breaks. |
UPLOAD_FILE_MAX_SIZE | 20 MB | Batch-uploaded park announcement summary files usually do not exceed 20 MB. This value supports conventional bulk import needs. |
Scheduled Sync Task Interval | Daily at 02:00 | Financing and filing data for daily reports is mostly published before 18:00 on the same day. Daily early morning sync ensures same-day data can be retrieved the next day. |
The parameter values provided on this page are common starting points 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: Retrieval results do not display source document metadata such as filing institution and loan date. Cause: The knowledge base's "retain source file metadata" configuration item is not enabled, so retrieval results cannot carry document source information.
- Phenomenon: Batch-uploaded monthly park financing summary files fail to parse and return a
504 Gateway Timeoutstatus code. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is set below 300 seconds, which cannot cover the full parsing time of structured tables. - Phenomenon: Searching for "soda ash financing" recalls financing projects from some glass manufacturing enterprises. Cause: The similarity threshold is set below 0.7, failing to filter results with low relevance to chemical raw material categories.
How to Verify Proper Configuration
- Upload a single chemical raw material financing daily report document. Check if parsed fields fully include preset fields such as financing entity, amount and usage, to confirm parsing configuration is active.
- Initiate a search for a specific chemical raw material category. Verify that the number of recall results falls within the preset recall range, to confirm retrieval parameter configuration is correct.
- Check scheduled sync task logs. Confirm that newly added financing daily report data from the current day has been incrementally synced to the knowledge base, with no delays or omissions.
- Check the metadata display area of retrieval results. Confirm that the filing date and publishing institution of the source document are displayed, to confirm the source retention configuration is enabled.
