What the data for this category looks like
Data for gas financing daily reports originates from internal financing ledgers of gas enterprises, filing information from local public utility supervision platforms, and supply chain financial transaction records. The update schedule covers daily publication of all financing transaction records from the previous day. Each entry is a structured item including fields such as transaction ID, upstream gas supply entity name, downstream gas user entity name, financing amount, financing term, fund cost rate, transaction date, and filing voucher number. Financing amount is measured in ten thousand RMB. Financing term is measured in natural days or natural months. Fund cost rate is expressed as a decimal.
What constraints these characteristics impose on the knowledge base retrieval and recall link
Standardize fields before retrieval to address format differences across multiple data sources, avoiding matching errors caused by abbreviated entity names or inconsistent amount units. Use a precise synchronization trigger configuration to match the daily incremental update rhythm, preventing resource waste from full re-scans. Enable multi-condition combined filtering for retrieval, leveraging the structured nature of multiple fields. Relying solely on single keyword matching cannot accurately target financing records. Automatically filter expired data during recall to account for the strong timeliness feature, reducing invalid results that occupy context resources.
Configuration settings
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
RECALL_TOP_N | Top 10 entries | The number of daily transaction entries for gas financing daily reports is usually within 10. Excessive recall increases context processing pressure |
SIMILARITY_THRESHOLD | 0.75-0.85 | Structured field matching requires a relatively high similarity threshold to avoid recalling financing records of unrelated entities |
PARSE_INCREMENTAL_SYNC_INTERVAL | 86400 seconds | Data is updated once daily. Synchronizing once per day covers the latest financing daily report data |
FIELD_MATCH_WEIGHT | Transaction entity:0.3, Transaction amount:0.2, Transaction term:0.2, Transaction date:0.3 | Entity and date are core filtering conditions in financing daily report retrieval, so higher weights should be assigned |
DOCUMENT_EXPIRE_DAYS | 30 days | Financing daily report data only retains valid records from the past 30 days. Expired data is automatically filtered out without retrieval |
PARSE_FILE_MAX_SIZE | 100 MB | The structured import file for a single gas financing daily report usually does not exceed this size, avoiding import timeouts |
The parameter values provided on this page are conventional recommendations used to determine the starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common errors
- Phenomenon: Empty results are returned during knowledge base search testing, or the interface prompts "No matching content found". Cause: No field matching weight is configured for the structured fields of gas financing daily reports, and only global keyword matching is relied on, which cannot accurately target core retrieval conditions such as entities and amounts.
- Phenomenon: An error
invalid configuration parameter name "hnsw.iter"is returned when starting a knowledge base retrieval task. Cause: Internal debugging parameters of the indexing engine are incorrectly filled into the FastGPT global configuration form, and the standardized parameter configuration items provided by the platform are not used. - Phenomenon: Non-bound enterprise accounts can view and retrieve the gas financing daily report data uploaded by the enterprise. Cause: Enterprise-level permission isolation configuration is not enabled, and the knowledge base is not bound and mapped to the corresponding enterprise account.
How to confirm the configuration is correct
- Upload a single test file of gas financing daily report, perform a retrieval test, and check whether the fields of the returned results are consistent with the uploaded data.
- View the synchronization log on the knowledge base configuration page to confirm that the incremental synchronization task is automatically executed according to the preset interval.
- Verify the permission isolation configuration, use a non-bound enterprise account to attempt retrieval, and confirm that the corresponding knowledge base cannot be accessed.
- Adjust the similarity threshold, observe the change in the matching accuracy of retrieval results, and confirm that the configuration meets business needs.
