What the Data for This Category Looks Like
Refractory materials-related financial report data primarily comes from periodic reports of publicly traded refractory material manufacturers and industry operation bulletins published by industry associations. Update cycles follow enterprise financial report schedules: annual reports are updated once per year, quarterly reports once per quarter, and industry bulletins are mostly updated monthly or quarterly. Document structures include modules such as revenue composition of the enterprise's refractory materials business, production capacity and utilization rate, raw material procurement and costs, R&D investment, and proportion of downstream application fields. Fields include refractory materials revenue (unit: 10,000 RMB), refractory product sales volume (unit: tons), unit product production cost (unit: yuan/ton), design production capacity (unit: tons/year), and some documents include separate revenue data for sub-categories such as refractory bricks and castable materials.
Constraints on Retrieval and Recall
Several characteristics of refractory materials financial report data impose clear constraints on the retrieval and recall link. Different data sources have large differences in update cycles, so recall filtering rules for corresponding time ranges must be configured to avoid recalling outdated industry bulletins or old financial reports. Revenue data for sub-categories such as refractory bricks and castable materials is scattered across different paragraphs, so entity association matching must be enabled to accurately retrieve refractory-related passages. Fields have dedicated units, so unit-bound retrieval rules must be configured to avoid confusing "tons" with weight units of other building material categories. Document lengths are generally long, so segment length must be adjusted to adapt to retrieval accuracy, and sorting issues for homogeneous content within the same industry must be addressed.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | Top 8–12 results | The stock of professional content related to refractory materials is limited; excessive recall will introduce irrelevant building material fragments |
similarity threshold | 0.75–0.82 | Refractory materials terminology is highly specialized; a threshold that is too low will recall general building material content unrelated to the business |
segment length | 800–1200 characters | Financial report documents have long lengths; overly long segments will destroy the contextual association of professional terms, while overly short segments will split complete business descriptions |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | A single complete financial report collection usually contains multi-page segmented data; the default parsing timeout cannot complete full parsing |
DATE_WEIGHT_BOOST | Increase weight of documents from the last 3 months by 1.2x, sort in reverse chronological order | Refractory materials financial report update cycles are clear; users need priority access to the latest data, and homogeneous content must be sorted by date |
UPLOAD_FILE_MAX_SIZE | 500 MB | Bulk-uploaded industry bulletin collections and enterprise financial report archives have large file sizes; this setting adapts to bulk import requirements |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing.
Three Common Errors
- Symptom: After performing a bulk reindex operation, some uploaded refractory materials financial report documents do not have updated content. Cause: Rules for triggering reindexing based on document metadata update time are not configured, and parsing is only completed during the initial upload.
- Symptom: When retrieving homogeneous refractory materials procurement cost passages, earlier published documents appear first. Cause: The date weight boost configuration is not enabled, or the weight coefficient is not matched to the financial report update cycle.
- Symptom: When parsing a financial report collection exceeding 200 pages, the task times out and returns a
504 Gateway Timeouterror. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted to a sufficient duration; the default timeout is not enough to complete parsing of large documents.
How to Verify Correct Configuration
- Upload a newly released refractory materials quarterly report document, perform a retrieval with the specified keyword, and verify that the arrangement position of this document in the recall results meets expectations.
- Import two homogeneous refractory materials cost analysis documents, retrieve content, and verify that the arrangement order of the documents follows the reverse chronological date rule.
- Upload a financial report collection exceeding 100 pages, and check whether the parsing task completes within the preset timeout period.
- Retrieve keywords including sub-categories such as "refractory bricks" and "castable materials", and verify that the recall results only include refractory materials-related content and do not include fragments from other building material categories.
