What the Data for This Category Looks Like
Plastics and rubber research report data primarily comes from public reports issued by industry associations, market data from commodity futures exchanges, research reports from basic chemical research teams at top securities firms, and customs import and export statistics. Spot data is updated daily. Industry monthly analysis reports are released monthly. Securities firm research reports are produced irregularly alongside industry events. Document structures typically include core market sections, industrial chain supply and demand analysis, policy interpretations, and future outlook. Structured fields cover spot prices, port inventories, monthly output, and other metrics, with units standardized to universal commodity measurement standards.
Constraints on the Knowledge Base Retrieval and Reranking Workflow
Differences in update rhythms across multiple data sources require the retrieval pipeline to adjust weights based on data timeliness, prioritizing recall of same-day spot data and recently released industry reports. Coexistence of structured fields and unstructured analysis content in document structures requires support for both keyword matching of structured fields and semantic recall of analysis paragraphs, to avoid missing key information with a single retrieval method. Significant variation in report length—from hundreds of words of industry briefs to tens of thousands of words of in-depth analysis—requires paragraph splitting to balance logical completeness and retrieval accuracy. Additionally, the high volume of industry-specific terminology requires the retrieval model to accurately match professional expressions for segmented product categories, preventing irrelevant content from appearing in recall results.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 12 entries | Plastics and rubber research reports contain multi-dimensional structured and unstructured data. A sufficient candidate set must first be recalled to cover information across different dimensions |
Similarity threshold | 0.72–0.78 | Balance semantic matching accuracy for industry terminology and recall coverage for niche segmented research reports, avoid missing segmented category data due to an overly high threshold |
Chunk size | 800–1200 characters | Adapt to long industrial chain analysis paragraphs in plastics and rubber research reports, avoid breaking logical connections by splitting segments too short |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Some large industry research reports have significant length, so sufficient time must be reserved for text parsing |
Rerank result count | Top 6 entries | After semantic reranking of the recalled candidate set, output the most relevant results for model invocation |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Adapt to the need for batch uploading industry database research reports, prevent large documents from being blocked during upload |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: An error "No available channel for model gpt-4o-mini under current group default" is returned during search. Cause: An independent model group is not configured for the exclusive plastics and rubber research report retrieval task, and no corresponding model channel is bound when using the default group.
- Issue: When referencing knowledge base documents in configuration variables, the required parameter content cannot be determined. Cause: The corresponding relationship between structured fields and document metadata of plastics and rubber research reports is not sorted out in advance, and parameter mapping rules are not clearly defined in the configuration.
- Issue: After local deployment, research report files are uploaded, and the data processing step returns empty content. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted to match the parsing duration of large research report documents, leading to parsing timeout and interruption.
How to Verify Successful Configuration
- Upload 1 to 2 typical plastics and rubber research reports. Confirm parsed segmented content retains core structured fields and analysis paragraphs, to validate the
Chunk sizeandPARSE_FILE_TIMEOUT_SECONDSconfigurations. - Input industry-specific terminology. Verify the number of recall results matches the configured
Recall count, and that similarity scores fall within the preset range. - Test variable reference configuration. Input preset parameters, confirm recall results only include documents matching the corresponding fields, to validate parameter mapping rule effectiveness.
- Upload research report attachments containing images. Check if complete image URLs are extracted in retrieval results, to validate image link processing configuration.
