What this category of data looks like
Carbon steel research report data mainly comes from monthly supply and demand reports from domestic steel industry associations, daily market briefings from major commodity trading platforms, and weekly production and operation reports from leading steel mills. Individual document lengths vary widely, from short market updates of a few hundred words to in-depth industry analyses of tens of thousands of words. Core fields include carbon steel grades such as Q235, HRB400, ex-factory prices, market inventory, and weekly output, with units mostly being yuan/ton, ten thousand tons, and thousand tons. Update frequencies cover daily, weekly, and monthly categories; some high-frequency market data is updated in real time alongside trading sessions.
Constraints imposed by these characteristics on citation source and traceability
The multi-update frequency feature of carbon steel research reports requires the traceability system to distinguish update timeliness tags for different documents, to avoid recalling outdated monthly reports for daily market queries. Segmentation of long documents must retain contextual associations of core fields, otherwise the traceability process cannot locate the specific grade or price range corresponding to the data. Data from multiple sources must be uniformly labeled with source institutions and release times, otherwise data credibility cannot be verified. The short text structure of some real-time market research reports requires that citation links or reference fragments can accurately match market snapshots from specific trading sessions, and only display relevant content from that period.
Configuration Settings
| Configuration Item | Recommended Value | Rationale for This Setting |
|---|---|---|
chunkSize | 800–1200 characters | Carbon steel research reports include both short market updates and long in-depth analyses. This range retains contextual associations of core fields such as grades and prices, avoiding loss of critical information during traceability |
recallTopK | Top 6–8 results | Carbon steel research reports have multiple segmentation dimensions such as production origin and grade. Too many recalled results will introduce irrelevant data, while too few will fail to cover all relevant reports |
similarityThreshold | 0.72–0.80 | Semantic similarity of carbon steel price data is relatively high. This threshold filters low-relevance historical reports while retaining comparative data for the same grade across different periods |
sourceDisplayFormat | Full source + release time | Source institutions and release times of carbon steel research reports are core basis for users to verify data credibility. Full display is required; only displaying file names cannot meet verification needs |
parseFileTimeout | 900 seconds | Some in-depth carbon steel research reports have large file sizes, requiring sufficient time to complete parsing and segmentation to avoid parsing timeouts |
enableCitation | Enabled | The professional nature of carbon steel research reports requires clear citation sources to meet compliance and data traceability requirements |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test against your own samples before finalizing.
Three Common Configuration Mistakes
- Symptom: An empty citation list appears after some queries, with the interface displaying "No relevant knowledge base documents matched". Cause: No timeliness filtering rules configured for the multi-update frequency of carbon steel research reports, causing the recall logic to fail to filter valid data from the current day or current week.
- Symptom: A large number of unparsed
|symbols appear in the context reference area, and the table structure in the research report cannot be displayed normally. Cause: ThechunkSizeparameter was not adjusted to fit the long text segmentation of carbon steel research reports, resulting in original Markdown table separators being retained and not cleaned up correctly during segmentation. - Symptom: Only file names are displayed for citation sources, with no release institution or time labeled. Cause: The
sourceDisplayFormatparameter was incorrectly configured to only return the file name field, without adding source institution and release time.
How to Verify Proper Configuration
- Upload a test document of a carbon steel research report, trigger a search, and check the citation list to confirm that the displayed sources include file names, release institutions, and relevant information.
- Enter a query containing a carbon steel grade such as Q235, verify the matching degree between the recalled reference documents and the query, and confirm that the recall logic meets business expectations.
- Upload a long in-depth research report, and check whether the segmented reference fragments retain contextual associations of core fields such as prices and grades.
- Check the system operation logs to confirm that no timeout errors are triggered when parsing carbon steel research reports.
